FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED)
When Four–wheel drive (4WD) is engaged, power is supplied to all four
wheels through a transfer case. 4WD power can be selected when
additional driving power is desired.
If equipped with the Electronic Shift 4WD System, and the
instrument panel control is moved to 4WD Low while the vehicle
is moving, the system will not engage and no damage will occur to
the 4WD system.
All utility-type vehicles and 4WD vehicles have special design and
equipment features to make them capable of performing in a wide
variety of off-road applications. Specific design characteristics give them
higher centers of gravity than ordinary passenger cars.
Utility and four-wheel drive vehicles arenotdesigned 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 or abrupt maneuvers in these
vehicles.
4WD operation is not recommended on dry pavement. Doing so could
result in difficult disengagement of the transfer case, increased tire wear
and decreased fuel economy.
Electronic shift on the fly (ESOF) 4x4 system (if equipped)
The 4WD system:
•provides 4x4 High engagement and disengagement while the vehicle is
moving.
•is operated by a rotary control located on the instrument panel that
allows you select 2WD, 4x4 High or 4x4 Low operation.
•uses hub locks that can be engaged and disengaged automatically by
using a rotary control located on the instrument panel.

4. Move the 4WD control to the 4x4
HIGH or 4x4 LOW position.
Driving off-road with 4WD
Your vehicle is specially equipped for driving on sand, snow, mud and
rough terrain and has operating characteristics that are somewhat
different from conventional vehicles, both on and off the road.
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. For more
information on driving off-road, read the “Four Wheeling” supplement in
your owner’s portfolio.
If your vehicle gets stuck
If the vehicle is stuck it may be rocked out by shifting from forward and
reverse gears, stopping between shifts, in a steady pattern. Press lightly
on the accelerator in each gear.
Do not rock the vehicle for more than a few minutes. The
transmission and tires may be damaged or the engine can
overheat.
Do not spin the wheels at over 56 km/h (35 mph). The tires may
fail and injure a passenger or bystander.

Sand
When driving over sand, try to keep all four wheels on the most solid
area of the trail. Do not reduce the tire pressures but shift to a lower
gear and drive steadily through the terrain. Apply the accelerator slowly
and avoid spinning the wheels.
Mud and water
If you must drive through high water, drive slowly. Traction or brake
capability may be limited.
When driving through water, determine the depth; avoid water higher
than the bottom of the hubs (if possible) and proceed slowly. If the
ignition system gets wet, the vehicle may stall.
Once through water, always try the brakes. Wet brakes do not stop the
vehicle as effectively as dry brakes. Drying can be improved by moving
your vehicle slowly while applying light pressure on the brake pedal.
After driving through mud, clean off residue stuck to rotating driveshafts
and tires. Excess mud stuck on tires and rotating driveshafts causes an
imbalance that could damage drive components.
If the transmission, transfer case or front axle are submerged in water,
their fluids should be checked and changed, if necessary.
Water intrusion into the transmission may damage the
transmission.
If the front or rear axle is submerged in water, the axle lubricant should
be replaced.
Driving on hilly or sloping terrain
When driving on a hill, avoid driving crosswise or turning on steep
slopes. You could lose traction and slip sideways. Drive straight up,
straight down or avoid the hill completely. Know the conditions on the
other side of a hill before driving over the crest.
When climbing a steep 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.
When descending a steep hill, avoid sudden braking. Shift to a lower gear
when added engine braking is desired.
When speed control is on and you are driving uphill, your vehicle speed
may drop considerably, especially if you are carrying a heavy load.
Driving
131

If vehicle speed drops more than 16 km/h (10 mph), the speed control
will cancel automatically. Resume speed with accelerator pedal.
If speed control cancels after climbing the hill, reset speed by pressing
and holding the SET ACCEL button to resume speeds over 50 km/h
(30 mph).
Automatic transmissions may shift frequently while driving up steep
grades. Eliminate frequent shifting by shifting out of
(Overdrive) into
a lower gear.
Driving on snow and ice
A 4WD vehicle has advantages over 2WD vehicles in snow and ice but
can skid like any other vehicle.
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.
If your vehicle is equipped with a Rear Anti-lock Brake System (RABS),
you should be careful when braking. Front brake lock-up, on any surface,
causes loss of steering control.
If your vehicle is equipped with a Four Wheel Anti-lock Brake System
(ABS), apply the brakes as you normally would. In order to allow the
ABS to operate properly, keep steady pressure on the brake pedal.
When driving on snow or ice with either braking system, allow more
stopping distance and drive slower than usual. Consider using one of the
lower gears.
VEHICLE LOADING
Before loading a vehicle, familiarize yourself with the following terms:
•Base Curb Weight: Weight of the vehicle including any standard
equipment, fluids, lubricants, etc. It does not include passengers or
aftermarket equipment.
•Payload: Combined maximum allowable weight of cargo, passengers
and optional equipment. The payload equals the gross vehicle weight
rating minus base curb weight.
•GVW (Gross Vehicle Weight): Base curb weight plus payload
weight. The GVW is not a limit or a specification.

5. The following steps are required to secure the support bracket (if
equipped) under the spare tire:
•Move the support bracket over the spare tire.
•Slide the support bracket over the eyebolt into the slot on the support
bracket.
•Tighten the eyebolt with tapered end of lug wrench leaving it
positioned at a right angle of the slot on the support bracket.
Tire change procedure
1. Park on a level surface, activate
hazard flashers and set the parking
brake.
•Automatic transmission: Place
gearshift lever in P (Park).
•Manual transmission: Place
gearshift lever in R (Reverse).
•Electronic Shift On the Fly four
wheel drive: Place transfer case
in 2WD, 4x4 HIGH or 4x4 LOW.
•Manual shift transfer case four
wheel drive: Place transfer case
in 2H, 4H or 4L.
To prevent the vehicle from
moving when you change a
tire, be sure the parking brake is
set, then block (in both
directions) the wheel that is
diagonally opposite (other side
and end of the vehicle) to the tire
being changed.
2. Turn engine OFF and block the diagonally opposite wheel (block not
provided).
3. Remove the jack, jack handle, lug wrench and spare tire from the
stowage locations.
4. Use the tip of the lug wrench to remove any wheel trim.
Roadside emergencies
155

•Resting your foot on the brake pedal while driving may reduce fuel
economy.
•Combine errands and minimize stop-and-go driving.
Maintenance
•Keep tires properly inflated and use only recommended size.
•Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
•Use recommended engine oil. Refer toLubricant Specifications.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle Scheduled Maintenance Guide.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
2 km/h [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
•Adding certain accessories to your vehicle (for example bug
deflectors, rollover/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•Using fuel blended with alcohol may lower fuel economy.
•Fuel economy may decrease with lower temperatures during the first
12–16 km (8–10 miles) of driving.
•Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
•Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
•Close windows for high speed driving.
EPA window sticker
Every new vehicle should have the EPA window sticker. Contact your
dealer if the window sticker is not supplied with your vehicle. The EPA
window sticker should be your guide for the fuel economy comparisons
with other vehicles.
