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
Recreationally Towing Your Vehicle
(page
384). 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.

WHAT IS THE ELECTRONIC
LOCKING DIFFERENTIAL
The electronic locking differential is a
device housed in the axles, and can provide
additional traction when needed.
HOW DOES THE ELECTRONIC
LOCKING DIFFERENTIAL
WORK
You can activate the differential
electronically and shift it on the fly within
the operating speed range. The electronic
differential will disengage when the vehicle
speed exceeds a set value and it will
reengage when the vehicle speed goes
below a set value. See Switching the
Electronic Locking Differential On and
Off
(page 237). The electronic locking
differential is for use in mud, rocks, sand,
or any off-road condition where you need
maximum traction.
Note: The electronic locking differential is
for off-road use only and is not for use on
dry pavement. Using the electronic locking
differential on dry pavement will result in
increased tire wear, noise and vibration. ELECTRONIC LOCKING
DIFFERENTIAL PRECAUTIONS
Operating the Electronic Locking
Differential with a Spare or
Mismatched Tires
On vehicles with an electronic locking
differential, the size of the spare tire can
affect performance of the system. If there
is a significant difference between the two
rear tires, you may have limited electronic
locking differential functionality. If the
system has difficulty disengaging, release
the accelerator pedal and turn the steering
wheel in the opposite direction when
rolling. We recommend engaging and
disengaging the electronic locking
differential at a stop when you mount a
spare on the rear axle.
SWITCHING THE ELECTRONIC
LOCKING DIFFERENTIAL ON
AND OFF - 4X4
Pull the electronic locking differential
switch towards you to turn on, to turn off
the electronic locking differential push the
knob back into the off position.

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
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes.
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.
LOCATING THE BRAKE FLUID
RESERVOIR
See
Under Hood Overview (page 397).
CHECKING THE BRAKE FLUID WARNING:
Do not use any fluid
other than the recommended brake fluid
as this will reduce brake efficiency. Use
of incorrect fluid could result in the loss
of vehicle control, serious personal injury
or death. WARNING:
Only use brake fluid
from a sealed container. Contamination
with dirt, water, petroleum products or
other materials may result in brake
system damage or failure. Failure to
adhere to this warning could result in the
loss of vehicle control, serious personal
injury or death. WARNING:
Do not allow the fluid
to touch your skin or eyes. If this
happens, rinse the affected areas
immediately with plenty of water and
contact your physician. WARNING:
The brake system
could be affected if the brake fluid level
is below the MIN mark or above the MAX
mark on the brake fluid reservoir.

DIESEL ENGINE EXHAUST
BRAKE – PRECAUTIONS
WARNING: Do not use tow/haul
when the road surface is slippery. Failure
to follow this instruction could result in
the loss of control of your vehicle. WARNING:
Do not use diesel
engine exhaust braking when the road
surface is slippery. Failure to follow this
instruction could result in the loss of
control of your vehicle.
USING THE DIESEL ENGINE
EXHAUST BRAKE
This feature increases engine braking at
higher engine speeds to provide better
grade descent control with less brake and
transmission wear and tear.
Note: Use this when driving downhill and
carrying heavy loads or trailering.
Benefits of engine braking are:
• Lower brake temperature.
• Reduced brake fade.
• Longer brake life.
• Improved driving and trailering control. Press the button on the switch
bank next to the audio unit to
switch the system on or off.
There are two engine brake modes, manual
and automatic.
Braking conditions must be met to use
exhaust brake:
• Your vehicle is in a forward gear.
• The engine speed is above 1500 RPM.
• Your foot is off the accelerator. You can use this feature with tow/haul, or
progressive range selection to provide
further increased engine braking. The
transmission upshifts to prevent the engine
from entering the red zone on the
tachometer.
Manual Engine Braking
1. Press the button to switch on manual
engine braking.
2. Release the accelerator pedal to maximize engine braking.
3. Apply the brakes. The transmission downshifts to lower gears.
Note: The engine braking feature only
functions when you release the accelerator.
Note: You can shift the transmission to
lower gears with progressive range selection
(PRS) or manual shifting independent of
pressing the brakes.
Note: You can also use manual engine
braking with cruise control to improve grade
descent control.
Note: If your vehicle has Adaptive Cruise
Control, the speed control system uses the
selected engine brake mode, transmission
gears, and brakes to maintain the set speed
and distance to the vehicle being followed.
Automatic Engine Braking
1. Press the button twice to switch on automatic engine braking.
2. Release the accelerator or brake pedal.
The system remembers your vehicle
speed.

HYDRAULIC POWER STEERING
ADAPTIVE STEERING
Note:
The adaptive steering system has
diagnostic checks that continuously monitor
the system. If the system detects a fault, a
message displays in the information display.
If a red warning message displays, stop your
vehicle as soon as it is safe to do so. The
message may clear if the fault is no longer
present. If an adaptive steering system
warning message appears each time you
start your vehicle, have the system checked
as soon as possible.
The adaptive steering system continually
changes the steering ratio with changes to
vehicle speed, optimizing the steering
response in all conditions. The system also
changes when you switch on the
transmission tow/haul feature. When you
select the tow/haul button, the adaptive
steering system reduces vehicle sensitivity
to steering inputs at higher vehicle speeds,
while maintaining the ease of parking and
maneuverability at low speeds.
Note: The adaptive steering system is
designed with a locking device. With the
lock engaged, the adaptive steering system
remains mechanically locked at a fixed
steering ratio. You may also notice a click
when you switch the vehicle on or after you
switch it off, as the lock disengages or
engages. Note:
If your vehicle loses electrical power
or detects a fault when you are driving, the
system automatically shuts down and you
retain normal steering function with a fixed
steering ratio. During this time, it is possible
that the steering wheel may not be straight
when the vehicle is driving straight ahead.
In addition, the driver may notice that the
steering wheel angle required to steer the
vehicle may be different.
Note: During parking maneuvers, the
adaptive steering system balances the driver
workload for various steering wheel inputs
and vehicle loading conditions. Under
extreme operating conditions the system
locking device may engage. This strategy
prevents overheating and permanent
damage to the adaptive steering system.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation.
