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.
SELECTING A FOUR-WHEEL
DRIVE MODE The four-wheel drive mode control is on
the instrument panel.
To select a four-wheel drive mode, rotate
the four-wheel drive mode control to
switch to the desired mode. You can select
two-wheel drive high (2H), or four-wheel
drive high (4H), at a stop or while driving.
Once the shift is complete, the information
display then displays the selected
four-wheel drive mode. While shifts are in
progress, you could see messages in the
information display indicating that a shift
is in progress or to release the accelerator
pedal to improve shift performance.

FOUR-WHEEL DRIVE MODES
TWO-WHEEL DRIVE HIGH
Two-wheel drive high is for general
on-road driving. Power's sent to the rear
wheels only.
FOUR-WHEEL DRIVE HIGH
Four-wheel drive high provides
electronically or mechanically locked
four-wheel drive power to both the front
and rear wheels for use in off-road or
winter conditions such as deep snow, sand
or mud. This mode is not for use on dry
pavement.
FOUR-WHEEL DRIVE LOW
Four-wheel drive low provides
electronically or mechanically locked
four-wheel drive power to both the front
and rear wheels for use on low traction
surfaces, but does so with additional
gearing for increased torque multiplication.
This mode is only for off-road conditions
such as deep sand, steep slopes, or pulling
heavy objects.

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

(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 Anti-Lock Braking System
Limitations (page 240). Note:
Excessive tire slippage can cause
transmission damage.

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.
