4L (4X4 LOW)
Uses extra gearing to provide maximum
power to all four wheels at reduced
speeds. Intended only for off-road
applications such as deep sand, steep
grades, or pulling heavy objects. 4L (4x4
low) will not engage while the vehicle is
moving above 3 mph (5 km/h); this is
normal and should be no reason for
concern. Refer to Shifting to or from 4L
(4x4 low) for proper operation.
Note:
Do not use 4L (4X4 LOW) on dry,
hard surfaced roads. Doing so can produce
excessive noise and increased tire wear. 4L
(4X4 LOW) is only intended for consistently
slippery or loose surfaces. Use of 4L (4X4
LOW) on these surfaces may produce some
noise (such as occasional clunks), but will
not damage drive components.
Note: The AdvanceTrac system has the
ability to take over control of the transfer
case clutch and disable it during driving
maneuvers when necessary.
Shifting between system modes
Note: Momentarily releasing the accelerator
pedal while performing a shift will improve
engagement/disengagement times.
Note: Do not perform this operation if the
rear wheels are slipping.
Note: Some noise may be heard as the
system shifts or engages; this is normal.
Note: 4X4 high mode is not intended for
use on dry pavement.
You can move the control from 2H or 4H
at a stop or while driving. The information
display may display a message indicating
a 4X4 shift is in progress. Once the shift is
complete the message center will then
display the system mode selected.
Shifting to or from 4L (4X4 low)

How Your Vehicle Differs From
Other Vehicles WARNING
Vehicles with a higher center of
gravity such as utility and four-wheel
drive vehicles handle differently than
vehicles with a lower center of gravity.
Utility and four-wheel drive vehicles are
not designed for cornering at speeds as
high as passenger cars any more than
low-slung sports cars are designed to
perform satisfactorily under off-road
conditions. Avoid sharp turns, excessive
speed and abrupt maneuvers in these
vehicles. Failure to drive cautiously could
result in an increased risk of loss of vehicle
control, vehicle rollover, personal injury and
death. Truck and utility vehicles can differ from
some other vehicles. Your vehicle may be
higher to allow it to travel over rough
terrain without getting hung up or
damaging underbody components. The differences that make your vehicle so
versatile also make it handle differently
than an ordinary passenger car.
Maintain steering wheel control at all
times, 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.
You should either know the terrain or
examine maps of the area before driving.
Map out your route before driving in the
area. To maintain steering and braking
control of your vehicle, you must have all
four wheels on the ground and they must
be rolling, not sliding or spinning.
Driving Off-Road With Truck and
Utility Vehicles
Note:
On some models, the initial shift from
two-wheel drive to four-wheel drive while
the vehicle is moving can cause some
momentary clunk and ratcheting sounds.
This is the front drivetrain coming up to
speed and the automatic locking hubs
engaging and is not cause for concern.
Note: Your vehicle may be equipped with
a front air dam that can become damaged
(due to reduced ground clearance) when
taking your vehicle off-road. This air dam
can be taken off by removing two bolts.
Four-wheel drive vehicles are specially
equipped for driving on sand, snow, mud
and rough terrain and have operating
characteristics that are somewhat
different from conventional vehicles, both
on and off the road.

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.
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 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. Note:
Excessive tire slippage can cause
transmission damage.
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 will not 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 Hints on Driving With
Anti-Lock Brakes (page 163).
If Your Vehicle Gets Stuck In Mud or
Snow WARNING
Do not spin the wheels at over 35
mph (56 km/h). The tires may fail
and injure a passenger or bystander.
If your vehicle gets stuck in mud or snow,
it may be rocked out by shifting between
forward and reverse gears, stopping
between shifts in a steady pattern. Press
lightly on the accelerator in each gear.
Note:
Do not rock your vehicle if the engine
is not at normal operating temperature,
damage to the transmission may occur.
Note: Do not rock your vehicle for more
than a minute, damage to the transmission
and tires may occur or the engine may
overheat.
Parking WARNINGS
If the parking brake is fully released,
but the brake warning lamp remains
illuminated, the brakes may not be
working properly. See your authorized
dealer.

LIMITED SLIP DIFFERENTIAL
(IF EQUIPPED)
This axle provides added traction on
slippery surfaces, particularly when one
wheel is on a poor traction surface. Under
normal conditions, the limited-slip axle
functions like a standard rear axle. The axle
may exhibit a slight noise or vibration
during tight turns with low vehicle speed.
This is normal behavior and indicates the
axle is working.
ELECTRONIC LOCKING
DIFFERENTIAL (IF EQUIPPED)
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.
The electronic locking differential is a
device housed in the rear axle that allows
both rear wheels to turn at the same
speed. The electronic locking differential
can provide additional traction should your
vehicle become stuck. You can activate
the differential electronically and shift it
on the fly within the differential operating
speed range. The differential is for use in
mud, rocks, sand, or any off-road condition
where you need maximum traction. It is
not for use on dry pavement.
The following conditions will affect the
electronic locking differential:
• The electronic locking differential will
not engage if your vehicle speed is
above 20 mph (32 km/h) in 4x2, 4x4
Auto, or 4x4 High modes
• The electronic locking differential will
not engage if your vehicle speed is
above or 56 mph (90 km/h) in 4X4
Low •
The electronic locking differential will
not engage if you press your
accelerator pedal beyond 50% during
an engagement attempt
• In 4x2, 4x4 Auto, and 4x4 High modes,
the electronic locking differential will
automatically disengage at speeds
above 25 mph (41 km/h) and will
automatically reengage at speeds
below 20 mph (32 km/h)
• In 4L (4X4 low), the electronic locking
differential will automatically
disengage at speeds above 62 mph
(100 km/h) and will automatically
reengage at speeds below 56 mph (90
km/h)
• The AdvanceTrac system has the
ability to take over control of the
electronic locking differential and
disable it during driving maneuvers
when necessary
When you switch the system on, if you do
not meet the required conditions for
electronic locking differential activation,
the instrument cluster will display the
appropriate information guiding you
through the proper activation process.
Activating the Electronic Locking
Differential
(If Equipped)
Note: Do not use electronic locking
differential on dry, hard surfaced roads.
Doing so will produce excessive noise,
vibration and increase tire wear.
Note: If the electronic locking differential
has difficulty disengaging, release the
accelerator pedal and turn the steering
wheel in the opposite direction while rolling.

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out. Have the
system checked by an authorized dealer. If
your vehicle has continuous vibration or
shudder in the steering wheel while braking,
have it checked by an authorized dealer.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Alloy
Wheels (page 264). See
Warning Lamps and
Indicators (page 82).
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.
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 selector lever
to position
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. Brake Assist
Brake assist detects when you brake
rapidly by measuring the rate at which you
press the brake pedal. It provides
maximum braking efficiency as long as you
press the pedal, and can reduce stopping
distances in critical situations.
Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking.
This lamp momentarily
illuminates when you turn the
ignition on. If the light does not
illuminate during start up, remains on or
flashes, the system may be disabled. Have
the system checked by an authorized
dealer. If the system is disabled, normal
braking is still effective. If the
brake warning lamp illuminates
when you release the parking brake, have
the system checked by an authorized
dealer.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
Note: When the system is operating, the
brake pedal will pulse and may travel
further. Maintain pressure on the brake
pedal. You may also hear a noise from the
system. This is normal.
The anti-lock braking system will not
eliminate the risks 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.

PARKING BRAKE
WARNING
Always set the parking brake fully
and make sure the transmission is
placed in park (P). Failure to set the
parking brake and engage park could result
in vehicle roll-away, property damage or
bodily injury. Turn the ignition to the lock
position and remove the key whenever you
leave your vehicle. Apply the parking brake whenever your
vehicle is parked. Press the pedal
downward to set the parking brake. The
brake warning lamp in the instrument
cluster will illuminate and remains
illuminated until the parking brake is
released.
To release, pull the brake release lever
located at the lower left side of the
instrument panel.
If you are parking your vehicle on a grade
or with a trailer, press and hold the brake
pedal down, then set the parking brake.
There may be a little vehicle movement as
the parking brake sets to hold the vehicle's
weight. This is normal and should be no
reason for concern. If needed, press and
hold the service brake pedal down, then
try reapplying the parking brake. Chock the
wheels if required. If the parking brake
cannot hold the weight of the vehicle, the
parking brake may need to be serviced or
the vehicle may be overloaded.
HILL START ASSIST
WARNINGS
The system does not replace the
parking brake. When you leave your
vehicle, always apply the parking
brake and put the transmission in park (P). WARNINGS
You must remain in your vehicle once
you have activated the system.
During all times, you are responsible
for controlling your vehicle,
supervising the system and
intervening, if required. If the engine is revved excessively, or
if a malfunction is detected, the
system will be deactivated.
The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake.
When the system is active, your vehicle will
remain stationary on the slope for two to
three seconds after you release the brake
pedal. This allows you time to move your
foot from the brake to the accelerator
pedal. The brakes are released
automatically once the engine has
developed sufficient drive to prevent your
vehicle from rolling down the slope. This
is an advantage when pulling away on a
slope, (for example from a car park ramp,
traffic lights or when reversing uphill into
a parking space).
The system will activate automatically on
any slope that will cause significant vehicle
rollback.
Using Hill Start Assist
1. Press the brake pedal to bring your
vehicle to a complete standstill. Keep
the brake pedal pressed.
2. If the sensors detect that your vehicle is on a slope, the system will activate
automatically.
3. When you remove your foot from the brake pedal, your vehicle will remain
on the slope without rolling away for
about two or three seconds. This hold
time will automatically be extended if
you are in the process of driving off.
