Driving your vehicle
Good braking practices Wet brakes can be dangerous! The
brakes may get wet if the vehicle is
driven through standing water or if it
is washed. Your vehicle will not stop
as quickly if the brakes are wet. Wet
brakes may cause the vehicle to pull
to one side.
To dry the brakes, apply the brakes
lightly until the braking action returns
to normal, taking care to keep the
vehicle under control at all times. If
the braking action does not return to
normal, stop as soon as it is safe to
do so and we recommend that you
call an authorized HYUNDAI dealer
for assistance.
DO NOT drive with your foot resting
on the brake pedal. Even light, butconstant pedal pressure can result in
the brakes overheating, brake wear,
and possibly even brake failure.If a tire goes flat while you are driv-
ing, apply the brakes gently and
keep the vehicle pointed straight
ahead while you slow down. When
you are moving slowly enough for it
to be safe to do so, pull off the road
and stop in a safe location.
Keep your foot firmly on the brake
pedal when the vehicle is stopped to
prevent the vehicle from rolling for-
ward.
Whenever leaving the vehicle or
parking, always come to a com-
plete stop and continue to
depress the brake pedal. Move
the shift lever into the P (Park)
position, then apply the parking
brake, and place the ignition
switch in the LOCK/OFF posi-tion.
Vehicles parked with the park- ing brake not applied or not
fully engaged may roll inadver-
tently and may cause injury to
the driver and others. ALWAYS
apply the parking brake before
exiting the vehicle.

The Four Wheel Drive (4WD)
System delivers engine power to all
front and rear wheels for maximum
traction. 4WD is useful when extra
traction is required on roads such
slippery, muddy, wet, or snow-cov-
ered roads. Occasional off-road use such as
established unpaved roads and trails
are OK. It is always important that
the driver carefully reduces the
speed to a level that does not exceed
the safe operating speed for those
conditions. Do not drive in water if the level
is higher than the bottom of the
vehicle.
Check your brake condition once you are out of mud or
water. Depress the brake pedal
several times as you move slow-
ly until you feel normal brakingreturn.
Shorten your scheduled mainte- nance interval if you drive in off-
road conditions such as sand,
mud or water (see "Maintenance
Under Severe Usage Conditions"
in chapter 7).
Always wash your vehicle thor- oughly after off road use, espe-
cially the bottom of the vehicle.
Be sure to equip the vehicle with four tires of the same size and
type.
Make sure that a full time 4WD vehicle is towed by a flat bed
tow truck.
NOTICE
FFOO UURR WW HHEEEELL DD RRIIVV EE (( 44 WW DD)) (( IIFF EE QQ UUIIPP PPEEDD ))
OOS057057 To reduce the risk of SERIOUS
INJURY or DEATH:
Do not drive in conditions that
exceed the vehicles intended
design such as challenging
off-road conditions.
Avoid high speeds when cor- nering or turning.
Do not make quick steering
wheel movements, such as
sharp lane changes or fast,sharp turns.
The risk of a rollover is great-
ly increased if you lose con-
trol of your vehicle at highwayspeeds.
Loss of control often occurs if
two or more wheels drop off
the roadway and the driver
over steers to reenter the
roadway.
In the event your vehicle
leaves the roadway, do not
steer sharply. Instead, slow
down before pulling back into
the travel lanes.

When the 4WD LOCK mode is
deactivated, a sensation may be
felt as the driving power is deliv-
ered entirely to the front wheels.
For safe 4WD operation
Before driving
Make sure all passengers arewearing seat belts.
Sit upright and closer to the steer- ing wheel than usual. Adjust the
steering wheel to a position com-
fortable for you to drive.
Driving on snow-covered or icy
roads
Start off slowly by applying theaccelerator pedal gently.
Use snow tires or tire chains.
Keep sufficient distance between your vehicle and the vehicle in front
of you.
Use engine braking during deceler- ation.
Avoid speeding, rapid acceleration, sudden brake applications, and
sharp turns to prevent skids.
Driving in sand or mud
Maintain slow and constant speed.
Use tire chains driving in mud ifnecessary.
Keep sufficient distance between your vehicle and the vehicle in front
of you.
Reduce vehicle speed and always check the road condition.
Avoid speeding, rapid acceleration, sudden brake applications, and
sharp turns to prevent getting
stuck.
NOTICE
When driving on normal roads,
deactivate the 4WD LOCK mode
by pushing the 4WD LOCK but-ton (4WD LOCK indicator light
goes off). Driving on normal
roads with the 4WD LOCK
mode, especially, when corner-
ing may cause mechanical
noise or vibration. The noiseand vibration will disappearwhen the 4WD LOCK mode is
deactivated. Prolong drivingwith the noise and vibration
may damage some parts of the
power train.
CAUTION
When the vehicle is stuck in
snow, sand or mud, place a non-slip material under the drive
wheels to provide traction OR
Slowly spin the wheels in for-
ward and reverse directions
which causes a rocking motion
that may free the vehicle.
However, avoid running the
engine continuously at high
rpm, doing so may damage the4WD system.

ground. For more information, refer
to "Towing" in chapter 6.
Dynamometer testing
A full-time 4WD vehicle must be test-
ed on a special four wheel chassis
dynamometer.A full-time 4WD vehicle should not
be tested on a 2WD roll tester. If a
2WD roll tester must be used, per-
form the following procedure:
1.Check the tire pressures recom-mended for your vehicle.
2.Place the front wheels on the roll tester for a speedometer test as
