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.
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 arenot
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 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.
4WD system indicator lights

If your vehicle gets stuck
If the vehicle is stuck, shift the
transmission in a steady motion
between forward and reverse
gears. Allow the transmission to
engage, then press lightly on the
accelerator.
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 35 mph (55 km/h).
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.

on the following charts. This is the
maximum trailer weight your
vehicle can tow and must fall
below the maximum shown under
maximum trailer weight on the
chart.
DRIVING THROUGH WATER
Do not drive quickly through
standing water, especially if the
depth is unknown. Traction or
brake capability may be limited
and if the ignition system gets wet,
your engine may stall. Water may
also enter your engine's air intake
and severely damage your engine.
If driving through deep or standing
water is unavoidable, proceed very
slowly. Never drive through water
that is higher than the bottom of
the hubs (truck)/wheel rims (car).
Once through the 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.
