The transmission is controlled using a rotary

electronic gear selector located on the instrument

panel. The transmission gear range (PRND) is

displayed both above the gear selector and in the

instrument cluster. To select a gear range, simply

rotate the gear selector. You must press the brake

pedal to shift the transmission out of PARK (or

NEUTRAL, when the vehicle is stopped or moving at

low speeds). To shift past multiple gear ranges at

once (such as PARK to DRIVE), simply rotate the

gear selector to the appropriate detent. Select the

DRIVE range for normal driving.

NOTE:

In the event of a mismatch between the gear

selector position and the actual transmission gear

(for example, driver selects PARK while driving),

the position indicator will blink continuously until

the selector is returned to the proper position, or

the requested shift can be completed.
The electronically-controlled transmission adapts

its shift schedule based on driver inputs, along

with environmental and road conditions. The

transmission electronics are self-calibrating;

therefore, the first few shifts on a new vehicle may

be somewhat abrupt. This is a normal condition,

and precision shifts will develop within a few

hundred miles (kilometers).
Only shift from DRIVE to PARK or REVERSE when

the accelerator pedal is released and the vehicle is

stopped. Be sure to keep your foot on the brake

pedal when shifting between these gears.
The transmission gear selector has only PARK,

REVERSE, NEUTRAL, and DRIVE positions. Manual

downshifts can be made using the Electronic

Range Select (ERS) shift control. Pressing the

GEAR -/GEAR + switches (on the steering wheel)

while in the DRIVE position will select the highest

available transmission gear, and will display that

gear limit in the instrument cluster as 1, 2, 3, etc

Ú

page 125. Some models will display both the

selected gear limit, and the actual current gear,

while in ERS mode.

Gear Ranges

Do not press the accelerator pedal when shifting

from PARK or NEUTRAL into another gear range.

NOTE:

After selecting any gear range, wait a moment to

allow the selected gear to engage before acceler

-

ating. This is especially important when the engine

is cold.
PARK (P)
This range supplements the parking brake by

locking the transmission. The engine can be

started in this range. Never attempt to use PARK

while the vehicle is in motion. Apply the parking

brake when exiting the vehicle in this range.

STARTING AND OPERATING

123

(Continued)

(Continued)

When parking on a hill, apply the parking brake

before shifting the transmission to PARK. As an

added precaution, turn the front wheels toward the

curb on a downhill grade and away from the curb

on an uphill grade.

NOTE:

On four-wheel drive vehicles be sure that the

transfer case is in a drive position.
When exiting the vehicle, always:



Apply the parking brake.



Shift the transmission into PARK.



Turn the engine off.



Remove the key fob.

WARNING!



Never use the PARK position as a substitute

for the parking brake. Always apply the

parking brake fully when exiting the vehicle to

guard against vehicle movement and possible

injury or damage.



Your vehicle could move and injure you and

others if it is not in PARK. Check by trying to

move the transmission gear selector out of

PARK with the brake pedal released. Make

sure the transmission is in PARK before

exiting the vehicle.



The transmission may not engage PARK if the

vehicle is moving. Always bring the vehicle to a

complete stop before shifting to PARK, and

verify that the transmission gear position indi

-

cator solidly indicates PARK (P) without

blinking. Ensure that the vehicle is completely

stopped, and the PARK position is properly

indicated, before exiting the vehicle.



It is dangerous to shift out of PARK or

NEUTRAL if the engine speed is higher than

idle speed. If your foot is not firmly pressing

the brake pedal, the vehicle could accelerate

quickly forward or in reverse. You could lose

control of the vehicle and hit someone or

something. Only shift into gear when the

engine is idling normally and your foot is firmly

pressing the brake pedal.



Unintended movement of a vehicle could

injure those in or near the vehicle. As with all

vehicles, you should never exit a vehicle while

the engine is running. Before exiting a vehicle,

always come to a complete stop, then apply

the parking brake, shift the transmission into

PARK, and turn the ignition OFF. When the

ignition is in the OFF mode, the transmission

is locked in PARK, securing the vehicle against

unwanted movement.

WARNING!



When exiting the vehicle, always make sure

the ignition is in the OFF mode, remove the

key fob from the vehicle, and lock the vehicle.



Never leave children alone in a vehicle, or with

access to an unlocked vehicle. Allowing chil

-

dren to be in a vehicle unattended is

dangerous for a number of reasons. A child or

others could be seriously or fatally injured.

Children should be warned not to touch the

parking brake, brake pedal or the transmis

-

sion gear selector.



Do not leave the key fob in or near the vehicle

(or in a location accessible to children), and do

not leave the ignition in the ACC or ON/RUN

mode. A child could operate power windows,

other controls, or move the vehicle.

CAUTION!



DO NOT race the engine when shifting from

PARK or NEUTRAL into another gear range, as

this can damage the drivetrain.



Before moving the transmission gear selector

out of PARK, you must start the engine, and

also press the brake pedal. Otherwise,

damage to the gear selector could result.

WARNING!

124

STARTING AND OPERATING

The following indicators should be used to ensure

that you have properly engaged the transmission

into the PARK position:



Look at the transmission gear position display

and verify that it indicates the PARK position (P),

and is not blinking.



With brake pedal released, verify that the gear

selector will not move out of PARK.

REVERSE (R)
This range is for moving the vehicle backward.

Shift into REVERSE only after the vehicle has come

to a complete stop.
NEUTRAL (N)
Use this range when the vehicle is standing for

prolonged periods with the engine running. Apply

the parking brake and shift the transmission into

PARK if you must exit the vehicle.

DRIVE (D)
This range should be used for most city and

highway driving. It provides the smoothest upshifts

and downshifts, and the best fuel economy. The

transmission automatically upshifts through all

forward gears.
When frequent transmission shifting occurs (such

as when operating the vehicle under heavy loading

conditions, in hilly terrain, traveling into strong

head winds, or while towing a heavy trailer), select

TOW/HAUL mode or use the Electronic Range

Select (ERS) shift control to select a lower gear

range

Ú

page 125. Under these conditions, using

a lower gear range will improve performance and

extend transmission life by reducing excessive

shifting and heat build-up.
During extremely cold temperatures (-22°F [-30°C]

or below), transmission operation may be modified

depending on engine and transmission

temperature as well as vehicle speed. Normal

operation will resume once the transmission

temperature has risen to a suitable level.

Transmission Limp Home Mode

Transmission function is monitored electronically

for abnormal conditions. If a condition is detected

that could result in transmission damage,

Transmission Limp Home Mode is activated. In this

mode, the transmission may operate only in

certain gears, or may not shift at all. Vehicle

performance may be severely degraded and the

engine may stall. In some situations, the

transmission may not re-engage if the engine is

turned off and restarted. The Malfunction Indicator

Light (MIL) may be illuminated. A message in the

instrument cluster will inform the driver of the

more serious conditions, and indicate what actions

may be necessary.
In the event of a momentary problem, the

transmission can be reset to regain all forward

gears by performing the following steps:

NOTE:

In cases where the instrument cluster message

indicates the transmission may not re-engage after

engine shutdown, perform this procedure only in a

desired location (preferably, at an authorized

dealer).
1. Stop the vehicle.
2. Shift the transmission into PARK, if possible. If

not, shift the transmission to NEUTRAL.

WARNING!

Do not coast in NEUTRAL and never turn off the

ignition to coast down a hill. These are unsafe

practices that limit your response to changing

traffic or road conditions. You might lose control

of the vehicle and have a collision.

CAUTION!

Towing the vehicle, coasting, or driving for any

other reason with the transmission in NEUTRAL

can cause severe transmission damage.

3. Push and hold the ignition switch until the

engine turns off.

4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the

problem is no longer detected, the

transmission will return to normal operation.

NOTE:

Even if the transmission can be reset, we

recommend that you visit an authorized dealer at

your earliest possible convenience. An authorized

dealer has diagnostic equipment to assess the

condition of your transmission.
If the transmission cannot be reset, authorized

dealer service is required.

Electronic Range Select (ERS) Operation

The ERS shift control allows the driver to limit the

highest available gear when the transmission is in

DRIVE. For example, if you set the transmission

gear limit to FOURTH gear, the transmission will

not shift above FOURTH gear (except to prevent

engine overspeed), but will shift through the lower

gears normally.
You can switch between DRIVE and ERS mode at

any vehicle speed. When the transmission gear

selector is in DRIVE, the transmission will operate

automatically, shifting between all available gears.

Tapping the GEAR “–” switch (on the steering

wheel) will activate ERS mode, display the current

gear in the instrument cluster, and set that gear as

the top available gear. Once in ERS mode, tapping

the GEAR “–” or GEAR “+” switch will change the

top available gear.

ERS Control

To exit ERS mode, simply push and hold the GEAR

“+” switch until the gear limit display disappears

from the instrument cluster.

When to Use TOW/HAUL Mode

When driving in hilly areas, towing a trailer, carrying

a heavy load, etc., and frequent transmission

shifting occurs, push the TOW/HAUL switch to

activate TOW/HAUL mode. This will improve

performance and reduce the potential for

transmission overheating or failure due to

excessive shifting.

TOW/HAUL Switch

The “TOW/HAUL Indicator Light” will illuminate in

the instrument cluster to indicate that TOW/HAUL

mode has been activated. Pushing the switch a

second time restores normal operation. Normal

operation is always the default at engine start-up.

If TOW/HAUL mode is desired, the switch must be

pushed each time the engine is started.

1 — GEAR “+” Switch
2 — GEAR “–” Switch

WARNING!

Do not downshift for additional engine braking

on a slippery surface. The drive wheels could

lose their grip and the vehicle could skid,

causing a collision or personal injury.

Shift the transmission into PARK.



Turn the engine off.



Remove the key fob.

WARNING!

Do not use the TOW/HAUL feature when driving

in icy or slippery conditions. The increased

engine braking can cause the rear wheels to

slide, and the vehicle to swing around with the

possible loss of vehicle control, which may

cause an accident possibly resulting in personal

injury or death.

WARNING!

(Continued)

(Continued)

The following indicators should be used to ensure

that you have properly engaged the transmission

into the PARK position:



When shifting into PARK, pull the gear selector

toward you and move it all the way counterclock

-

wise until it stops.



Release the gear selector and make sure it is

fully seated in the PARK gate.



Look at the transmission gear position display

and verify that it indicates the PARK position (P).



With brake pedal released, verify that the gear

selector will not move out of PARK.

REVERSE (R)
This range is for moving the vehicle backward.

Shift into REVERSE only after the vehicle has come

to a complete stop.
NEUTRAL (N)
Use this range when the vehicle is standing for

prolonged periods with the engine running. The

engine may be started in this range. Apply the

parking brake and shift the transmission into PARK

if you must exit the vehicle.



Your vehicle could move and injure you and

others if it is not in PARK. Check by trying to

move the gear selector out of PARK with the

brake pedal released. Make sure the trans

-

mission is in PARK before exiting the vehicle.



It is dangerous to shift out of PARK or

NEUTRAL if the engine speed is higher than

idle speed. If your foot is not firmly pressing

the brake pedal, the vehicle could accelerate

quickly forward or in reverse. You could lose

control of the vehicle and hit someone or

something. Only shift into gear when the

engine is idling normally and your foot is firmly

Unintended movement of a vehicle could

injure those in or near the vehicle. As with all

vehicles, you should never exit a vehicle while

the engine is running. Before exiting a vehicle,

always come to a complete stop, then apply

the parking brake, shift the transmission into

PARK, turn the engine OFF, and remove the

key fob. When the ignition is in the LOCK/OFF

(key removal) position (or, with Keyless Enter

‘n Go™, when the ignition is in the OFF mode),

the transmission is locked in PARK, securing

the vehicle against unwanted movement.

WARNING!



When leaving the vehicle, always make sure

the ignition is in the OFF mode, remove the

key fob from the vehicle, and lock the vehicle.



Never leave children alone in a vehicle, or with

access to an unlocked vehicle. Allowing chil

STARTING AND OPERATING

DRIVE (D)
This range should be used for most city and

highway driving. It provides the smoothest upshifts

and downshifts, and the best fuel economy. The

transmission automatically upshifts through all

forward gears.
When frequent transmission shifting occurs (such

as when operating the vehicle under heavy loading

conditions, in hilly terrain, traveling into strong

head winds, or while towing a heavy trailer), select

TOW/HAUL mode or use the Electronic Range

Select (ERS) shift control to select a lower gear

range

Ú

page 129. Under these conditions, using

a lower gear range will improve performance and

extend transmission life by reducing excessive

shifting and heat buildup.
If the transmission temperature exceeds normal

operating limits, the powertrain controller will

modify the transmission shift schedule and expand

the range of torque converter clutch engagement.

This is done to prevent transmission damage due

to overheating.
If the transmission becomes extremely hot or is in

danger of overheating, the “Transmission

Temperature Warning Light” may illuminate and

the transmission may operate differently until the

transmission cools down.

NOTE:

Use caution when operating a heavily loaded

vehicle at low speeds (such as towing a trailer up a

steep grade, or in stop-and-go traffic) during hot

weather. In these conditions, torque converter slip

can impose a significant additional heat load on

the cooling system. Downshifting the transmission

to the lowest possible gear (when climbing a

grade), or shifting to NEUTRAL (when stopped in

heavy traffic) can help to reduce this excess heat

generation.
During cold temperatures, transmission operation

may be modified depending on engine and

transmission temperature as well as vehicle

speed. This feature improves warm-up time of the

engine and transmission to achieve maximum

efficiency. Engagement of the torque converter

clutch is inhibited until the transmission fluid is

warm

Ú

page 130.

On trucks with AS66RC or AS69RC transmission,

FIFTH and SIXTH gears may be inhibited briefly on

cold starts below 41°F (5°C), and during very cold

temperatures (-4°F [-20°C] or below), operation

may briefly be limited to third gear only. During this

condition, the ability of the vehicle to accelerate

under heavily loaded conditions may be reduced.

In all cases, normal operation will resume once the

transmission temperature has risen to a suitable

level.

Transmission Limp Home Mode

Transmission function is monitored electronically

for abnormal conditions. If a condition is detected

that could result in transmission damage,

Transmission Limp Home Mode is activated. In this

mode, the transmission remains in THIRD gear

regardless of which forward gear is selected. If an

AS66RC/AS69RC equipped truck enters Limp

Home Mode at highway speeds, it will initially

engage FIFTH gear, until the vehicle slows to a

speed where THIRD gear can be engaged. PARK,

REVERSE, and NEUTRAL will continue to operate.

The Malfunction Indicator Light (MIL) may be

illuminated. Limp Home Mode allows the vehicle to

be driven to an authorized dealer for service

without damaging the transmission.

WARNING!

Do not coast in NEUTRAL and never turn off the

ignition to coast down a hill. These are unsafe

practices that limit your response to changing

traffic or road conditions. You might lose control

of the vehicle and have a collision.

CAUTION!

Towing the vehicle, coasting, or driving for any

other reason with the transmission in NEUTRAL

can cause severe transmission damage.

In the event of a momentary problem, the

transmission can be reset to regain all forward

gears by performing the following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the

problem is no longer detected, the

transmission will return to normal operation.

NOTE:

Even if the transmission can be reset, we

recommend that you visit an authorized dealer at

your earliest possible convenience. An authorized

dealer has diagnostic equipment to assess the

condition of your transmission.
If the transmission cannot be reset, authorized

dealer service is required.

Electronic Range Select (ERS) Operation

The ERS shift control allows the driver to limit the

highest available gear when the transmission is in

DRIVE. For example, if you set the transmission

gear limit to FOURTH gear, the transmission will

not shift above FOURTH gear, but will shift through

the lower gears normally.

You can switch between DRIVE and ERS mode at

any vehicle speed. When the gear selector is in the

DRIVE position, the transmission will operate

automatically, shifting between all available gears.

Tapping the ERS “-” switch will activate ERS mode,

display the current gear in the instrument cluster,

and set that gear as the top available gear. Once in

ERS mode, tapping “-” or “+” will change the top

available gear.

Electronic Range Select

To exit ERS mode, simply push and hold the ERS

“+” switch until the gear limit display disappears

from the instrument cluster.

NOTE:

To select the proper gear position for maximum

deceleration (engine braking), simply push and

hold the ERS “-” switch. The transmission will shift

to the range from which the vehicle can best be

slowed down.

1 — GEAR “+” Switch
2 — GEAR “–” Switch

WARNING!

Do not downshift for additional engine braking

on a slippery surface. The drive wheels could

lose their grip and the vehicle could skid,

causing a collision or personal injury.

CAUTION!

When using ERS for engine braking while

descending steep grades, be careful not to

overspeed the engine. Apply the brakes as

needed to prevent engine overspeed.

4

130

STARTING AND OPERATING

Overdrive Operation

The automatic transmission includes an

electronically controlled Overdrive (FIFTH and

SIXTH gears). The transmission will automatically

shift into Overdrive if the following conditions are

present:



The gear selector is in the DRIVE position.



The transmission fluid has reached an

adequate temperature.



The engine coolant has reached an adequate

temperature.



Vehicle speed is sufficiently high.



The TOW/HAUL switch has not been activated.



The driver is not heavily pressing the acceler

-

ator.

Torque Converter Clutch

A feature designed to improve fuel economy has

been included in the automatic transmission on

your vehicle. A clutch within the torque converter

engages automatically at calibrated speeds. This

may result in a slightly different feeling or response

during normal operation in the upper gears. When

the vehicle speed drops or during some

accelerations, the clutch automatically

disengages.

NOTE:



The torque converter clutch will not engage,

until the transmission fluid and engine coolant

are warm (usually after 1 to 3 miles (2 to 5 km)

of driving). Because engine speed is higher

when the torque converter clutch is not

engaged, it may seem as if the transmission is

not shifting properly when cold; This is normal.

Using the Electronic Range Select (ERS) shift

control, when the transmission is sufficiently

warm, will demonstrate that the transmission is

able to shift into and out of Overdrive.



If the vehicle has not been driven for several

days, the first few seconds of operation after

shifting the transmission into gear may seem

sluggish. This is due to the fluid partially

draining from the torque converter into the

transmission. This condition is normal and will

not cause damage to the transmission. The

torque converter will refill within five seconds

after starting the engine.

When To Use TOW/HAUL Mode

When driving in hilly areas, towing a trailer, carrying

a heavy load, etc., and frequent transmission

shifting occurs, push the TOW/HAUL switch to

activate TOW/HAUL mode. This will improve

performance and reduce the potential for

transmission overheating or failure due to

excessive shifting. When operating in TOW/HAUL

mode, transmission upshifts are delayed, and the

transmission will automatically downshift (for

engine braking) when the throttle is closed and/or

during steady braking maneuvers.

TOW/HAUL Switch

The “TOW/HAUL Indicator Light” will illuminate in

the instrument cluster to indicate that TOW/HAUL

mode has been activated. Pushing the switch a

second time restores normal operation. Normal

operation is always the default at engine start-up.

If TOW/HAUL mode is desired, the switch must be

pushed each time the engine is started.

AUXILIARY SWITCHES — IF EQUIPPED

There can be up to six auxiliary switches located in

the lower switch bank of the instrument panel

which can be used to power various electronic

devices and Power Take Off (PTO). If equipped, it

will take the place of the sixth auxiliary switch.

Connections to the switches are found under the

hood in the connectors attached to the auxiliary

Power Distribution Center.
You have the ability to configure the functionality of

the auxiliary switches via the instrument cluster

display. All switches can now be configured for

setting the switch type operation to latching or

momentary, power source of either battery or

ignition, and ability to hold last state across key

cycles.

NOTE:

Holding last state conditions are met when switch

type is set to latching and power source is set to

information below:
2WD
Two-Wheel Drive High Range — This range is for

normal street and highway driving on dry, hard

surfaced roads.

WARNING!

Do not use the TOW/HAUL feature when driving

in icy or slippery conditions. The increased

engine braking can cause the rear wheels to

slide, and the vehicle to swing around with the

possible loss of vehicle control, which may

cause an accident possibly resulting in personal

injury or death.

132

STARTING AND OPERATING

4WD HIGH
Four-Wheel Drive High Range — This range

provides torque to the front driveshaft (engages

four-wheel drive) which allows front and rear

wheels to spin at the same speed. This provides

additional traction for loose, slippery road surfaces

only.
4WD LOW
Four-Wheel Drive Low Range — This range provides

low speed four-wheel drive. It maximizes torque

(increased torque over 4WD High) to the front

driveshaft, allowing front and rear wheels to rotate

at the same speed. This range provides additional

traction and maximum pulling power for loose,

slippery road surfaces only. Do not exceed 25 mph

(40 km/h) in this range.
N (Neutral)
N (Neutral) — This range disengages both the front

and rear driveshafts from the powertrain. To be

used for flat towing behind another vehicle

This electronically shifted transfer case is designed

to be driven in the two-wheel drive position (2WD)

for normal street and highway conditions on dry

hard surfaced roads. Driving the vehicle in

two-wheel drive will have greater fuel economy

benefits as the front axle is not engaged in

two-wheel drive.

When additional traction is required, the transfer

case 4WD High and 4WD Low positions can be

used to maximize torque to the front driveshaft,

forcing the front and rear wheels to rotate at the

same speed. This is accomplished by pushing the

desired position on the four-wheel drive control

switch.
For specific shifting instructions

You or others could be injured or killed if you

leave the vehicle unattended with the transfer

case in the N (NEUTRAL) position without first

fully engaging the parking brake. The transfer

case N (NEUTRAL) position disengages both

the front and rear drive shaft from the power

-

train, and will allow the vehicle to roll, even if

the transmission is in PARK. The parking

brake should always be applied when the

driver is not in the vehicle.



The transmission may not engage PARK if the

vehicle is moving. Always bring the vehicle to a

complete stop before shifting to PARK, and

verify that the transmission gear position indi

-

cator solidly indicates PARK (P) without

blinking. Ensure that the vehicle is completely

stopped, and the PARK position is properly

indicated, before exiting the vehicle.

STARTING AND OPERATING

If All Of The Following Shift Conditions Are Met:
1. The current position indicator light will turn

off.

2. The selected position indicator light will flash

until the transfer case completes the shift.

3. When the shift is complete, the indicator light

for the selected position will stop flashing and

remain on.

If One Or More Of The Following Shift Conditions

Are Not Met:
1. The indicator light for the current position will

remain on.

2. The newly selected position indicator light will

continue to flash.

3. The transfer case will not shift.

NOTE:

Before retrying a selection, make certain that all

the necessary requirements for selecting a new

transfer case position have been met. To retry the

selection, push the current position, wait five

seconds, and retry selection

The “SVC 4WD Warning Light” monitors the

electronically shifted four-wheel drive system. If

this light remains on after engine start up or

illuminates during driving, it means that the

four-wheel drive system is not functioning properly

and that service is required.

NOTE:

Do not attempt to make a shift while only the front

or rear wheels are spinning. This could cause

damage to driveline components.
When operating your vehicle in 4WD Low, the

engine speed is approximately three times that of

the two-wheel drive or 4WD High positions at a

given road speed. Take care not to overspeed the

engine and do not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles

depends on tires of equal size, type and

circumference on each wheel. Any difference in

tire size can cause damage to the drivetrain.
Because four-wheel drive provides improved

traction, there is a tendency to exceed safe turning

and stopping speeds. Do not go faster than road

conditions permit.

Shifting Procedure

NOTE:



If any of the requirements to select a new

transfer case position have not been met, the

transfer case will not shift. The position indi

-

cator light for the previous position will remain

on and the newly selected position indicator

light will continue to flash until all the require

ments for the selected position have been met.



If all the requirements to select a new transfer

case position have been met, the current posi

tion indicator light will flash until the transfer

case completes the shift. When the shift is

complete, the position indicator light for the

selected position will stop flashing and remain

on.

2WD TO 4WD HIGH

Push the desired position on the four-wheel drive

control switch to shift the transfer case. Shifts

between two-wheel drive and 4WD High can be

done with the vehicle stopped or in motion. With

the vehicle in motion, the transfer case will

engage/disengage faster if you momentarily

release the accelerator pedal after turning the

control switch. If the vehicle is stopped, the ignition

switch must be in the ON position with the engine

either running or off. This shift cannot be

completed if the ignition switch is in the ACC

position.

NOTE:

The four-wheel drive system will not allow shifts

between 2WD/4WD High if the front and/or rear

the selected position indicator light will flash and

the original position indicator light will remain on.

At this time, reduce speed and stop spinning the

wheels to complete the shift.

2WD OR 4WD HIGH TO 4WD LOW

NOTE:

When shifting into or out of 4WD Low some gear

noise may be heard. This noise is normal and is not

detrimental to the vehicle or occupants.
Shifting can be performed with the vehicle rolling

2 to 3 mph (3 to 5 km/h) or completely stopped.

You can use either of the following procedures:
Preferred Procedure
1. With the engine running, slow the vehicle to

2 to 3 mph (3 to 5 km/h).

2. Shift the transmission into NEUTRAL.
3. While still rolling, push the desired position on

the transfer case control switch.

4. After the desired position indicator light is on

(not flashing), shift the transmission back into

gear.

Alternate Procedure
1. Bring the vehicle to a complete stop.
2. With the ignition switch in the ON position and

the engine running, shift the transmission into

NEUTRAL.

3. Push the desired position on the transfer case

control switch.

4. After the desired position indicator light is on

(not flashing), shift the transmission back into

gear.

NOTE:



If Steps 1 or 2 of either the Preferred or Alter

-

nate Procedure are not satisfied prior to

attempting the shift, then the desired position

indicator light will flash continuously while the

original position indicator light is on, until all

requirements have been met.



The ignition switch must be in the ON position

for a shift to take place and for the position indi

-

cator lights to be operable. If the ignition switch

is not in the ON position, the shift will not take

place and no position indicator lights will be on

or flashing.
