3. Turn the ignition off.
WARNING: Do not park your vehicle in Neutral, it may move
unexpectedly and injure someone. Use 1 (First) gear and set
the parking brake fully.
Removing the key
Turn the ignition off, push the
release lever (located above the
ignition), then turn the key toward
you and remove the key.
If your vehicle gets stuck in mud or snow
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.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED)
WARNING: For important information regarding safe operation
of this type of vehicle, see Preparing to drive your vehicle in
this chapter.
Four–wheel drive (4WD) supplies power to all four wheels. 4WD should
not be operated on dry pavement; driveline damage may occur.
If equipped with the Electronic Shift 4WD System, and 4WD Low
is selected while the vehicle is moving above 3 mph (5 km/h), the
4WD system will not engage. This is normal and should be no
reason for concern.Refer toShifting to/from 4WD Lowfor proper
operation.

If your vehicle goes off the edge of the pavement
•If your vehicle goes off the edge of the pavement, slow down, but
avoid severe brake application, ease the vehicle back onto the
pavement only after reducing your speed. Do not turn the steering
wheel too sharply while returning to the road surface.
•It may be safer to stay on the apron or shoulder of the road and slow
down gradually before returning to the pavement. You may lose
control if you do not slow down or if you turn the steering wheel too
sharply or abruptly.
•It often may be less risky to strike small objects, such as highway
reflectors, with minor damage to your vehicle rather than attempt a
sudden return to the pavement which could cause the vehicle to slide
sideways out of control or roll over. Remember, your safety and the
safety of others should be your primary concern.
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.
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 if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a few minutes or damage
to the transmission and tires may occur or the engine may
overheat.
WARNING: Do not spin the wheels at over 35 mph (56 km/h).
The tires may fail and injure a passenger or bystander.

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 the 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.
Driving through deep water where the transmission vent tube is
submerged may allow water into the transmission and cause
internal transmission damage.
Replace rear axle lubricant any time the axle has been submerged in
water. The rear axle does not normally require a lubricant change for the
life of the vehicle. Rear axle lubricant quantities are not to be checked or
changed unless a leak is suspected or repair is required.
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.
If vehicle speed drops more than 10 mph (16 km/h), 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 30 mph
[50 km/h]).
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.
When braking, apply the brakes as you normally would. In order to allow
the anti-lock brake system (ABS) to operate properly, keep steady
pressure on the brake pedal.
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.
DRIVING THROUGH WATER
If driving through deep or standing
water is unavoidable, proceed very
slowly especially when the depth is
not known. Never drive through
water that is higher than the bottom
of the wheel rims (for cars) or the
bottom of the hubs (for trucks).
When driving through water, traction or brake capability may be limited.
Also, water may enter your engine’s air intake and severely damage your
engine or your vehicle may stall.Driving through deep water where
the transmission vent tube is submerged may allow water into the
transmission and cause internal transmission damage.
Once through the water, always dry the brakes by moving your
vehicle slowly while applying light pressure on the brake pedal.
Wet brakes do not stop the vehicle as quickly as dry brakes.

HAZARD FLASHER CONTROL
The hazard flasher is located on the
steering column, just behind the
steering wheel. The hazard flashers
will operate when the ignition is in
any position or if the key is not in
the ignition.
Push in the flasher control and all
front and rear direction signals will
flash. Press the flasher control again
to turn them off. Use it when your
vehicle is disabled and is creating a
safety hazard for other motorists.
Note:With extended use, the flasher may run down your battery.
FUEL PUMP SHUT-OFF SWITCH
This device stops the electric fuel pump from sending fuel to the engine
when your vehicle has had a substantial jolt.
After an accident, if the engine cranks but does not start, this switch
may have been activated.
