STARTING AND OPERATING

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

Ú

page 159.

The 4WD High and 4WD Low positions are

designed for loose, slippery road surfaces only.

Driving in the 4WD High and 4WD Low positions

on dry, hard surfaced roads may cause increased

tire wear and damage to the driveline

components.

NOTE:

The transfer case Neutral button is located in the

center of the four-wheel drive Control Switch and

is pushed by using a ballpoint pen or similar

object. The transfer case Neutral position is to be

used for recreational towing only

Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights

(4WD High and 4WD Low) are located in the

instrument cluster and indicate the current and

desired transfer case selection. When you

select a different transfer case position, the

indicator lights will do the following:
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

Ú

page 159.

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.



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 indicator solidly indicates PARK (P)

without blinking. Ensure that the vehicle is

completely stopped, and the PARK position

is properly indicated, before exiting the

vehicle.

WARNING!

(Continued)

STARTING AND OPERATING

155

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

indicator light for the previous position will

remain on and the newly selected position

indicator light will continue to flash until all

the requirements for the selected position

have been met.



If all the requirements to select a new

transfer case position have been met, the

current position indicator light will turn off,

the selected position indicator light will flash

until the transfer case completes the shift.

When the shift is complete, the position indi

-

cator 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 wheels are spinning (no traction). In this

situation, 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.

WARNING!

Always engage the parking brake when

powering down the vehicle if the “SVC 4WD

Warning Light” is illuminated. Not engaging

the parking brake may allow the vehicle to roll

which may cause personal injury or death.

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 posi

-

tion 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

indicator lights to be operable. If the ignition

page 159.

STARTING AND OPERATING

161

The 4H and 4L positions are intended for loose,

slippery road surfaces only. Driving in the 4H

and 4L positions on dry, hard surfaced roads

may cause increased tire wear and damage to

the driveline components.
The “Transfer Case Position Indicator Light” in

the instrument cluster will alert the driver that

the vehicle is in four-wheel drive and that the

front and rear driveshafts are locked together.

This light will illuminate when the transfer case

is shifted into either the 4H or 4L position. There

is no light for the 2H or N (Neutral) positions on

some models.
When operating your vehicle in 4L, the engine

speed is approximately three times that of the

4H or 4L 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

will adversely affect shifting and can cause

damage to the drivetrain.

NOTE:

Do not attempt to make a shift while only the

front or rear wheels are spinning, as this can

cause damage to driveline components.

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.

NOTE:

Delayed shifts out of four-wheel drive may be

experienced due to uneven tire wear, low or

uneven tire pressures, excessive vehicle

loading, or cold temperatures.

Shifting Procedure — Manually Shifted

Transfer Case

2H To 4H

Shifting between 2H and 4H can be made with

the vehicle stopped or in motion. If the vehicle

is in motion, shifts can be made up to 55 mph

(88 km/h). With the vehicle in motion, the

transfer case will engage/disengage faster if

you momentarily release the accelerator pedal

after completing the shift. Apply a constant

force when shifting the transfer case lever.

2WD High Or 4WD High To 4WD Low

NOTE:

When shifting into or out of 4L some gear noise

may be heard. This noise is normal and is not

detrimental to the vehicle or occupants.

With the vehicle rolling at 2 to 3 mph (3 to

5 km/h), shift the transmission into NEUTRAL.

While the vehicle is coasting at 2 to 3 mph (3 to

5 km/h), shift the transfer case lever firmly to

the desired position. Do not pause in transfer

case Neutral.

WARNING!

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 shafts from the powertrain

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.

162

STARTING AND OPERATING

NOTE:



Pausing in transfer case N (Neutral) in vehi

-

cles equipped with an automatic transmis

-

sion may require shutting the engine OFF to

avoid gear clash while completing the shift. If

difficulty occurs, shift the transmission into

Neutral, hold your foot on the brake, and turn

the engine OFF. Complete the range shift to

the desired mode.



Shifting into or out of 4L is possible with the

vehicle completely stopped, however difficulty

may occur due to the mating clutch teeth not

being properly aligned. Several attempts may

be required for clutch teeth alignment and

shift completion to occur. The preferred

method is with the vehicle rolling 2 to 3 mph

(3 to 5 km/h). Avoid attempting to engage or

disengage 4L with the vehicle moving faster

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



Do not attempt to shift into or out of 4L while

the transmission is in gear.

Transfer Case Position Indicator Light

The “Transfer Case Position Indicator Light” in

the instrument cluster is used to alert the driver

that the front axle is fully engaged and all four

wheels are driving.

LIMITED-SLIP DIFFERENTIAL

The limited-slip differential provides additional

traction on snow, ice, mud, sand and gravel,

particularly when there is a difference between

the traction characteristics of the surface under

the right and left rear wheels. During normal

driving and cornering, the limited-slip unit

performs similarly to a conventional differential.

On slippery surfaces, however, the differential

delivers more of the driving effort to the rear

wheel having the better traction.
The limited-slip differential is especially helpful

during slippery driving conditions. With both rear

wheels on a slippery surface, a slight application

of the accelerator will supply maximum traction.

When starting with only one rear wheel on an

excessively slippery surface, slight momentary

application of the parking brake may be

necessary to gain maximum traction.

Care should be taken to avoid sudden

accelerations when both rear wheels are on a

slippery surface. This could cause both rear

wheels to spin, and allow the vehicle to slide

sideways on the crowned surface of a road or in

a turn.

WARNING!

On vehicles equipped with a limited-slip

differential never run the engine with one rear

wheel off the ground since the vehicle may

drive through the rear wheel remaining on the

ground. You could lose control of the vehicle.

TEERING

The standard power steering system will give

you good vehicle response and increased ease

of maneuverability in tight spaces. The system

will provide mechanical steering capability if

power assist is lost.
If for some reason the power assist is interrupted,

it will still be possible to steer your vehicle. Under

these conditions, you will observe a substantial

increase in steering effort, especially at very low

vehicle speeds and during parking maneuvers.

NOTE:



Increased noise levels at the end of the

steering wheel travel are considered normal

and do not indicate that there is a problem

with the power steering system.



Upon initial start-up in cold weather, the

power steering pump may make noise for a

short amount of time. This is due to the cold,

thick fluid in the steering system. This noise

should be considered normal, and it does not

in any way damage the steering system.

Power Steering Fluid Check

Checking the power steering fluid level at a

defined service interval is not required. The fluid

should only be checked if a leak is suspected,

abnormal noises are apparent, and/or the

system is not functioning as anticipated. Check

fluid level when the engine is cold and off.

Coordinate inspection efforts through an

authorized dealer.

CAUTION!

Prolonged operation of the steering system

at the end of the steering wheel travel will

increase the steering fluid temperature and it

should be avoided when possible. Damage to

the power steering pump may occur.

WARNING!

Fluid level should be checked on a level

surface and with the engine off to prevent

injury from moving parts and to ensure

accurate fluid level reading. Do not overfill.

Use only manufacturer's recommended

power steering fluid.

Adaptive Cruise Control (ACC) increases the

driving convenience provided by Cruise Control

while traveling on highways and major roadways.

However, it is not a safety system and not

designed to prevent collisions. The Cruise Control

function performs differently if your vehicle is not

equipped with ACC

Ú

page 164.

ACC will allow you to keep Cruise Control

engaged in light to moderate traffic conditions

without the constant need to reset your speed.

ACC utilizes a radar sensor and a forward facing

camera designed to detect a vehicle directly

ahead of you to maintain a set speed.

NOTE:



If the ACC sensor detects a vehicle ahead,

ACC will apply limited braking or acceleration

(not to exceed the original set speed) auto

-

matically to maintain a preset following

distance, while matching the speed of the

vehicle ahead.



Any chassis/suspension or tire size modifica

-

tions to the vehicle will affect the perfor

-

mance of the Adaptive Cruise Control and

Forward Collision Warning system.



Fixed Speed Cruise Control alone (an ACC

distance not set) will not detect vehicles

directly ahead of you. Always be aware of the

mode selected.

WARNING!



Adaptive Cruise Control (ACC) is a conve

-

nience system. It is not a substitute for active

driver involvement. It is always the driver’s

responsibility to be attentive of road, traffic,

and weather conditions, vehicle speed,

distance to the vehicle ahead; and, most

importantly, brake operation to ensure safe

operation of the vehicle under all road condi

-

tions. Your complete attention is always

required while driving to maintain safe

control of your vehicle. Failure to follow these

warnings can result in a collision and death

or serious personal injury.



The ACC system:



Does not react to pedestrians,

oncoming vehicles, and stationary

objects (e.g., a stopped vehicle in a

traffic jam or a disabled vehicle).



Cannot take street, traffic, and weather

conditions into account, and may be

limited upon adverse sight distance

conditions.

STARTING AND OPERATING

(Continued)

Adaptive Cruise Control (ACC) Operation

The buttons on the right side of the steering

wheel operate the ACC system.

Adaptive Cruise Control Buttons



Does not always fully recognize

complex driving conditions, which can

result in wrong or missing distance

warnings.



Will bring the vehicle to a complete stop

while following a target vehicle and hold

the vehicle for approximately two seconds

in the stop position. At this point, there will

be an “ACC may cancel soon” chime and

warning to the driver. When ACC is

cancelled, the system will release the

brakes and the driver must take over

braking. The system can be resumed when

the target vehicle drives off by releasing

the brake and pushing the resume button

on the steering wheel.

WARNING!

(Continued)

You should switch off the ACC system:



When driving in fog, heavy rain, heavy

snow, sleet, heavy traffic, and complex

driving situations (i.e., in highway construc

-

tion zones).



When entering a turn lane or highway off

ramp; when driving on roads that are

winding, icy, snow-covered, slippery, or

have steep uphill or downhill slopes.



When towing a trailer up or down steep

slopes.



When circumstances do not allow safe

driving at a constant speed.

instrument cluster display.
The ACC screen may display once again if any of

the following ACC activity occurs:



System Cancel



Driver Override



System Off



ACC Proximity Warning



ACC Unavailable Warning

The instrument cluster display will return to the

last display selected after five seconds of no

ACC display activity.

Activating Adaptive Cruise Control (ACC)

The minimum set speed for the ACC system is

20 mph (32 km/h).
When the system is turned on and in the ready

state, the instrument cluster display will read

“ACC Ready.”
When the system is off, the instrument cluster

display will read “Adaptive Cruise Control (ACC)

Off.”

NOTE:

You cannot engage ACC under the following

conditions:



When in 4WD Low



When brakes are applied



When the parking brake is applied



When the automatic transmission is in PARK,

REVERSE or NEUTRAL



When the vehicle speed is below the

minimum speed range



When the brakes are overheated



To Set A Desired ACC Speed

When the vehicle reaches the speed

desired, push the SET (-) button and release.

The instrument cluster display will show the set

speed.

NOTE:

Fixed Speed Cruise Control can be used without

an ACC distance set. To change between the

different modes, push the ACC on/off button

which turns the ACC and the Fixed Speed Cruise

Control off. Pushing the Fixed Speed Cruise

Control on/off button will result in turning on

(changing to) Fixed Speed Cruise Control mode.

If ACC is set when the vehicle speed is below

20 mph (32 km/h), the set speed will default to

20 mph (20 km/h).

NOTE:

Fixed Speed Cruise Control cannot be set below

20 mph (32 km/h).

If either system is set when the vehicle speed is

above 20 mph (32 km/h), the set speed shall

be the current speed of the vehicle.

NOTE:



Keeping your foot on the accelerator pedal

can cause the vehicle to continue to accel

-

erate beyond the set speed. If this occurs, the

message “ACC DRIVER OVERRIDE” will

display in the instrument cluster display.



If you continue to accelerate beyond the set

speed while an ACC distance is also set, the

system will not be controlling the distance

between your vehicle and the vehicle ahead.

The vehicle speed will only be determined by

the position of the accelerator pedal.

To Cancel

The following conditions cancel the ACC or Fixed

Speed Cruise Control systems:



The brake pedal is applied.



The CANCEL button is pushed.



An Anti-Lock Brake System (ABS) event

occurs.

WARNING!

Leaving the Adaptive Cruise Control (ACC)

system on when not in use is dangerous.

You could accidentally set the system or

cause it to go faster than you want. You could

lose control and have a collision. Always leave

the system off when you are not using it.

WARNING!

In the Fixed Speed Cruise Control mode

(no ACC distance set), the system will not

react to vehicles ahead. In addition, the

proximity warning does not activate and no

alarm will sound even if you are too close to

the vehicle ahead since neither the presence

of the vehicle ahead nor the vehicle-to-vehicle

distance is detected. Be sure to maintain a

safe distance between your vehicle and the

vehicle ahead. Always be aware which mode

is selected.
