MANUALLY SHIFTING GEARS
SHIFTING USING THE BUTTONS
ON THE SELECTOR LEVER
Pressing the manual (M) button on the
shifter allows you to select the gear you
prefer. Only the current gear displays. Press
the
+
button to upshift or the
–
button to
downshift. Return the transmission to a
different gearshift position to deactivate
manual control or press manual (M).
Your vehicle has a SelectShift Automatic
transmission gearshift lever. This gives you
the ability to change gears up or down,
without a clutch, as preferred.
Note:
To prevent the engine from running
at too low an RPM, which could cause it to
stall, SelectShift still makes some
downshifts if it determines that you have
not downshifted in time. Although
SelectShift makes some downshifts for you,
it still allows you to downshift at any time
if it determines that damage to the engine
from over-revving does not occur.
Note:
SelectShift does not automatically
upshift, even if the engine is approaching
the RPM limit. Shift manually by pressing
the
+
button.
Note:
Engine damage could occur if you
maintain excessive engine revving without
shifting.

POWER TAKE-OFF
(IF EQUIPPED)
HOW DOES THE POWER TAKE-
OFF WORK
Auxiliary equipment called power take-off,
or PTO, is often added to the engine or
transmission to operate utility equipment.
Examples include a wheel-lift for tow
trucks, cranes, tools for construction or tire
service, and pumping fluids. PTO
applications draw auxiliary horsepower
from the powertrain, often while the
vehicle is stationary. In this condition, there
is limited cooling air flow through the
radiator and around the vehicle that
normally occurs when a vehicle is moving.
The aftermarket PTO system installer,
having the most knowledge of the final
application, is responsible for determining
whether additional chassis heat protection
or powertrain cooling is required, and
alerting the user to the safe and proper
operation.
Note:
Use of auxiliary equipment that
exceeds the maximum Power Take-Off
(PTO) load specified in our Truck Body
Builders Layout Book can adversely affect
the performance of the powertrain system.
Refer to the Body Builders Layout Book for
instructions about the appropriate
installation of additional equipment.
For additional information, visit
WHAT IS THE SPLIT SHAFT
CAPABILITY
Split shaft capability is when the output
gear connects directly with the engine to
power your power takeoff (PTO), anytime
the engine is running.
This feature is approved as a stationary
mobile power source, within the limits and
operating guidelines detailed in our Truck
Body Builders Layout Book. For additional

HOW DOES FOUR-WHEEL
DRIVE WORK
Using the Electronic Shift On the
Fly System
(If Equipped)
This four-wheel drive system utilizes a
2-speed Electronic Shift On the Fly (ESOF)
transfer case which is also known as a
part-time system. This system offers the
driver two-wheel drive high, four-wheel
drive high, and four-wheel drive low as
available modes of operation. When you
select either four-wheel drive high or
four-wheel drive low, the system provides
mechanically locked four-wheel drive
power to both the front and rear wheels
for use in off-road or slippery conditions
such as deep snow, sand or mud. When
you select four-wheel drive low, the system
provides additional gearing for increased
torque multiplication for conditions like
deep sand, steep slopes, or pulling heavy
objects. Additionally, the system is capable
of recreational flat towing by putting the
transfer case into a neutral position. See

A
E339076
For proper operation, make sure that each
hub is fully engaged and that both hub
locks are set to the same position (both
set to lock or both set to auto). To engage
lock, turn the hub locks completely
clockwise. To engage auto, turn the hub
locks completely counterclockwise.
The ESOF four-wheel drive system:
•
Provides 4x4 High engagement and
disengagement while the vehicle is
moving.
•
Operates by a rotary control located
on the instrument panel that allows
you select 4x2, 4x4 High or 4x4 Low
operation.
•
Uses auto-manual hub locks that can
be engaged and disengaged
automatically based on the 4x4 mode
you select.
•
Increases fuel economy when used in
the hub lock's recommended auto
mode.
Note:
Auto-manual hub locks manually
lock by rotating the hub lock control from
auto to lock.
FOUR-WHEEL DRIVE
PRECAUTIONS
WARNING:
Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death.
228
Four-Wheel Drive
(If Equipped)
WARNING:
If the parking brake is
fully released, but the brake warning
lamp remains illuminated, the brakes
may not be working properly. Have your
vehicle checked as soon as possible.
WARNING:
Do not become
overconfident in the ability of four-wheel
drive vehicles. Although a four-wheel
drive vehicle may accelerate better than
a two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive
at a safe speed.
Truck and utility vehicles can differ from
some other vehicles. Your vehicle could be
higher to allow it to travel over rough
terrain without getting stuck or damaging
underbody components. The differences
that make your vehicle so versatile also
make it handle differently than an ordinary
passenger car. Always maintain steering
wheel control, especially in rough terrain.
Since sudden changes in terrain can result
in abrupt steering wheel motion, make sure
you grip the steering wheel from the
outside. Do not grip the spokes. Drive
cautiously to avoid vehicle damage from
concealed objects such as rocks and
stumps. Drive slower in strong crosswinds
which can affect the normal steering
characteristics of your vehicle. Be
extremely careful when driving on
pavement made slippery by loose sand,
water, gravel, snow or ice.
Note:
Do not use four-wheel drive high or
four-wheel drive low mode on dry, hard
surfaced roads. Doing so can produce
excessive noise, increase tire wear and can
damage drive components. Four-wheel
drive high or four-wheel drive low modes
are for consistently slippery or loose
surfaces. Use of four-wheel drive low mode
on these surfaces could produce some
noise, such as occasional clunks, but should
not damage drive components. When
transitioning from consistently loose or
slippery surfaces, be sure the four-wheel
drive systems not mechanically blocked
once on dry, hard surfaced roads in
two-wheel drive high.
Parking
WARNING:
If the parking brake is
fully released, but the brake warning
lamp remains illuminated, the brakes
may not be working properly. Have your
vehicle checked as soon as possible.
WARNING:
Apply the parking
brake, shift into park (P), switch the
ignition off and remove the key before
you leave your vehicle. Failure to follow
this instruction could result in personal
injury or death.
On some four-wheel drive vehicles, when
the transfer case is in the neutral (N)
position, the engine and transmission
disconnects from the rest of the driveline.
Therefore, the vehicle is free to roll even if
the automatic transmission is in park (P)
or the manual transmission is in gear. Do
not leave the vehicle unattended with the
transfer case in the neutral (N) position.
Always set the parking brake fully and turn
off the ignition when leaving the vehicle.
229
Four-Wheel Drive
(If Equipped)
FOUR-WHEEL DRIVE
LIMITATIONS
Do not use four-wheel drive high or
four-wheel drive low mode on dry, hard
surfaced roads. Doing so can produce
excessive noise, increase tire wear and can
damage drive components. four-wheel
drive high or four-wheel drive low modes
intended for consistently slippery or loose
surfaces. Use of four low mode on these
surfaces could produce some noise, such
as occasional clunks, but should not
damage drive components. When
transitioning from consistently loose or
slippery surfaces, be sure the four-wheel
drive systems not mechanically blocked
once on dry, hard surfaced roads in
two-wheel drive high.
Operating Four-Wheel Drive with
a Spare or Mismatched tires
On four-wheel drive vehicles, the size of
the spare tire can affect the four-wheel
drive system. If there is a significant
difference between the size of the spare
tire and the remaining tires, you could have
limited four-wheel drive functionality.
When driving with the full-size dissimilar
spare wheel and tire assembly, do not:
•
Exceed 50 mph (80 km/h) with a
four-wheel drive mode turned on.
•
Turn on a four-wheel drive mode
unless the vehicle is stationary.
•
Use a four-wheel drive mode on dry
pavement.
When driving with the full-size dissimilar
spare wheel and tire assembly, four-wheel
drive functionality is limited, especially
when driving in a mechanically locked
four-wheel drive mode. You can experience
the following:
•
Additional noise from the transfer case
or other drive components.
•
Difficulty shifting out of a mechanically
locked four-wheel drive mode.
Use of a dissimilar spare wheel and tire
assembly can lead to impairment of the
following:
•
Comfort and noise.
•
Winter weather driving capability.
•
Wet driving capability.
•
Four-wheel drive capability.

FOUR-WHEEL DRIVE DRIVING
HINTS
EMERGENCY MANEUVERS
In an unavoidable emergency situation
where a sudden sharp turn must be made,
remember to avoid over-driving your
vehicle (i.e. turn the steering wheel only as
rapidly and as far as required to avoid the
emergency). Excessive steering can result
in loss of vehicle control. Apply smooth
pressure to the accelerator pedal or brake
pedal when changes in vehicle speed are
required. Avoid abrupt steering,
acceleration and braking. This could result
in an increased risk of vehicle roll over, loss
of vehicle control and personal injury. Use
all available road surface to bring your
vehicle to a safe direction of travel.
In the event of an emergency stop, avoid
skidding the tires and do not attempt any
sharp steering wheel movements.
If your vehicle goes from one type of
surface to another (i.e. from concrete to
gravel) there can be a change in the way
your vehicle responds to a maneuver, i.e.
steering, acceleration or braking.
DRIVING IN SAND
When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Avoid reducing the tire pressures but shift
to a lower gear and drive steadily through
the terrain. Apply the accelerator slowly
and avoid excessive wheel slip.
When driving at slow speeds in deep sand
under high outside temperatures, use a low
gear when possible. Low gear operation
can maximize the engine and transmission
cooling capability.
Avoid driving at excessive speed. This
causes vehicle momentum to work against
you and your vehicle could become stuck
to the point that assistance may be
required from another vehicle. Remember,
you may be able to back out the way you
came if you proceed with caution.
DRIVING THROUGH MUD AND
WATER
WARNING:
Do not spin the wheels
at over 34 mph (55 km/h). The tires may
fail and injure a passenger or bystander.
232
Four-Wheel Drive
(If Equipped)
Mud
Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even four-wheel drive vehicles can
lose traction in slick mud. If your vehicle
does slide, steer in the direction of the slide
until you regain control of your vehicle.
After driving through mud, clean off residue
stuck to rotating driveshafts and tires.
Excess mud stuck on tires and rotating
driveshafts can cause an imbalance that
could damage drive components.
Water
If you must drive through high water, drive
slowly. Traction or brake capability may
be limited. When driving through water,
determine the depth and avoid water
higher than the bottom of the hubs. If the
ignition system gets wet, your vehicle may
stall. Once through water, test the brakes.
Wet brakes do not stop your vehicle as
effectively as dry brakes. Drying improves
by applying light pressure to the brake
pedal while moving slowly.
Note:
Driving through deep water may
damage the transmission. If the front or rear
axle is submerged in water, the axle
lubricant and power transfer unit lubricant
should be checked and changed if
necessary.
DRIVING ON HILLY OR SLOPING
TERRAIN
Although natural obstacles may make it
necessary to travel diagonally up or down
a hill or steep incline, you should try to drive
straight up or straight down.
Note:
Avoid turning on steep slopes or hills.
A danger lies in losing traction, slipping
sideways and possible vehicle roll over.
Whenever driving on a hill, determine
beforehand the route you can use. Do not
drive over the crest of a hill without seeing
what conditions are on the other side. Do
not drive in reverse over a hill without the
aid of an observer.
When climbing a steep slope or hill, start
in a lower gear rather than downshifting to
a lower gear from a higher gear once the
ascent has started. This reduces strain on
the engine and the possibility of stalling.
If your vehicle stalls, do not try to
turnaround because this could cause
vehicle roll over. It is better to reverse back
to a safe location.
Apply just enough power to the wheels to
climb the hill. Too much power can cause
the tires to slip, spin or lose traction,
resulting in loss of vehicle control.
Descend a hill in the same gear you would
use to climb up the hill to avoid excessive
brake application and brake overheating.
Do not descend in neutral. Disengage
overdrive or move the transmission
selector lever to a lower gear. When
descending a steep hill, avoid sudden hard
braking as you could lose control. The front
wheels have to be turning in order to steer
your vehicle.
Note:
If your vehicle has anti-lock brakes,
apply the brakes steadily. Do not pump the
brakes.
DRIVING ON SNOW AND ICE
WARNING:
If you are driving in
slippery conditions that require tire
chains or cables, then it is critical that
you drive cautiously. Keep speeds down,
allow for longer stopping distances and
avoid aggressive steering to reduce the
233
Four-Wheel Drive
(If Equipped)
chances of a loss of vehicle control
which can lead to serious injury or death.
If the rear end of your vehicle slides while
cornering, steer in the direction of the
slide until you regain control of your
vehicle.
Four-wheel drive vehicles have advantages
over two-wheel drive vehicles in snow and
ice but can skid like any other vehicle.
Should you start to slide while driving on
snowy or icy roads, turn the steering wheel
in the direction of the slide until you regain
control.
Avoid sudden applications of power and
quick changes of direction on snow and
ice. Apply the accelerator slowly and
steadily when starting from a full stop.
Avoid sudden braking. Although a
four-wheel drive vehicle may accelerate
better than a two-wheel drive vehicle in
snow and ice, it cannot stop any faster as
braking occurs at all four wheels. Do not
become overconfident as to road
conditions.
Make sure you allow sufficient distance
between you and other vehicles for
stopping. Drive slower than usual and
consider using one of the lower gears. In
emergency stopping situations, apply the
brake steadily. Do not pump the brake
pedal. See
Note:
Excessive tire slippage can cause
transmission damage.

BRAKE PRECAUTIONS
WARNING:
Driving your vehicle
with the warning lamp on is dangerous.
A significant decrease in braking
performance may occur. It may take you
longer to stop your vehicle. Have your
vehicle checked as soon as possible.
Driving extended distances with the
parking brake engaged can cause brake
failure and the risk of personal injury.
Wet brakes result in reduced braking

ANTI-LOCK BRAKING SYSTEM
ANTI-LOCK BRAKING SYSTEM
LIMITATIONS
The anti-lock braking system does not
eliminate the risk of crash when:
•
You drive too closely to the vehicle in
front of you.
•
Your vehicle is hydroplaning.
•
You take corners too fast.
•
The road surface is poor.
Note:
If the system activates, the brake
pedal could pulse and could travel further.
Maintain pressure on the brake pedal.
BRAKE OVER ACCELERATOR
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Move the transmission to park (P),
switch the engine off and apply the parking
brake. Inspect the accelerator pedal for
any interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
