Driving your vehicle
✽✽NOTICE
 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. Press the
brake pedal several times as you move
slowly until you feel normal braking
forces return.
 Shorten your scheduled maintenance interval if you drive in off-road condi-
tions such as sand, mud or water (see
“Maintenance under severe usage
conditions” in section 7). Always wash
your vehicle thoroughly after off road
use, especially cleaning the bottom of
the vehicle.
 Since the driving torque is always
applied to the 4 wheels the perform-
ance of the AWD vehicle is greatly
affected by the condition of the tires.
Be sure to equip the vehicle with four
tires of the same size and type.
 A full time four wheel drive vehicle cannot be towed by an ordinary tow
truck. Make sure that the vehicle is
placed on a flat bed truck for moving.Reducing the risk of a rollover
This multi-purpose passenger vehicle is
defined as a Sports Utility Vehicle (SUV).
SUV’s have higher ground clearance and
a narrower track to make them capable
of performing in a wide variety of off-road
applications. Specific design characteris-
tics give them a higher center of gravity
than ordinary vehicles. An advantage of
the higher ground clearance is a better
view of the road, which allows you to
anticipate problems. They are not
designed for cornering at the same
speeds as conventional passenger vehi-
cles, any more than low-slung sports
cars are designed to perform satisfactori-
ly in off-road conditions. Due to this risk,
driver and passengers are strongly rec-
ommended to buckle their seat belts. In
a rollover crash, an unbelted person is
more likely to die than a person wearing
a seat belt. There are steps that a driver
can make to reduce the risk of a rollover.
If at all possible, avoid sharp turns or
abrupt maneuvers, do not load your roof
rack with heavy cargo, and never modify
your vehicle in any way.
CAUTION - Mud or snow
If one of the front or rear wheels
begins to spin in mud, snow, etc.the vehicle can sometimes be driv-
en out by depressing the accelera-tor pedal further; however avoid
running the engine continuously athigh rpm because doing so could
damage the AWD system.
WARNING - AWD driving
Avoid high cornering speed.
Do not make quick steering wheel movements, such as sharp
lane changes or fast, sharp turns.
The risk of rollover is greatly increased if you lose control of
your vehicle at high speed.
In a collision, an unbelted person is significantly more likely to die
compared to a person wearing a seat belt.
Loss of control often occurs if two or more wheels drop off the
roadway and the driver over
steers to re-enter the roadway. In
the event your vehicle leaves the
roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.

523
Driving your vehicle
Full-time AWD vehicles must be testedon a special four wheel chassis
dynamometer.
✽✽ NOTICE
Never engage the parking brake while
performing these tests.
A full-time AWD vehicle should not be tested on a 2WD roll tester. If a 2WD
roll tester must be used, perform the
following: 1. Check the tire pressures recommend-
ed for your vehicle.
2. Place the front wheels on the roll tester for a speedometer test as shown
in the illustration.
3. Release the parking brake.
4. Place the rear wheels on the tempo- rary free roller as shown in the illustra- tion.
WARNING - Dynamometer testing
Keep away from the front of the
vehicle while the vehicle is in gear
on the dynamometer. This is very
dangerous as the vehicle can jump
forward and cause serious injury ordeath.
OCM051044LRoll tester (speedometer)Temporary free roller
CAUTION
When lifting up the vehicle, do not
operate front and rear wheel sep-arately. All four wheels should be
operated.
If you need to operate the front wheel and rear wheel when lifting
up the vehicle, you should release the parking brake.

Power brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
In the event that the power-assisted
brakes lose power because of a stalled
engine or some other reason, you can
still stop your vehicle by applying greater
force to the brake pedal than you nor-
mally would. The stopping distance, how-
ever, will be longer.
When the engine is not running, the
reserve brake power is partially depleted
each time the brake pedal is applied. Do
not pump the brake pedal when the
power assist has been interrupted.
Pump the brake pedal only when neces-
sary to maintain steering control on slip-
pery surfaces. BRAKE SYSTEM WARNING
- Brakes
Do not drive with your foot rest-
ing on the brake pedal. This will create abnormal high brake tem-
peratures, excessive brake lining
and pad wear, and increasedstopping distances.
When descending a long or steep hill, shift to a lower gear and
avoid continuous application of
the brakes. Continuous brake application will cause the brakes
to overheat and could result in a
temporary loss of braking per-
formance.
Wet brakes may impair the vehi- cle’s ability to safely slow down;
the vehicle may also pull to one side when the brakes are applied.
Applying the brakes lightly will
indicate whether they have been
affected in this way. Always test
your brakes in this fashion after
driving through deep water. To
dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance returns to normal.
(Continued)
(Continued)
Always, confirm the position ofthe brake and accelerator pedal
before driving. If you don't checkthe position of the accelerator
and brake pedal before driving,
you may depress the accelerator
instead of the brake pedal. It maycause a serious accident.

Driving your vehicle
In the event of brake failure
If service brakes fail to operate while the
vehicle is in motion, you can make an
emergency stop with the parking brake.
The stopping distance, however, will be
much greater than normal.
Disc brakes wear indicator
Your vehicle has disc brakes.
When your brake pads are worn and new
pads are required, you will hear a high-
pitched warning sound from your front
brakes or rear brakes. You may hear this
sound come and go or it may occur
whenever you depress the brake pedal.
Please remember that some driving con-
ditions or climates may cause a brake
squeal when you first apply (or lightly
apply) the brakes. This is normal and does
not indicate a problem with your brakes.
Parking brake
Applying the parking brake
■■Foot type
To engage the parking brake, first apply
the foot brake and then depress the park-
ing brake pedal down as far as possible.
WARNING- Brake wear
This brake wear warning sound
means your vehicle needs service.
If you ignore this audible warning,
you will eventually lose braking
performance, which could lead to a serious accident.
CAUTION
To avoid costly brake repairs, do not continue to drive with wornbrake pads.
Always replace the front or rear brake pads as pairs.
OLM059014
WARNING- Parking brake
Applying the parking brake while
the vehicle is moving at normal
speeds can cause a sudden loss of
control of the vehicle. If you mustuse the parking brake to stop the
vehicle, use great caution in apply-
ing the brake.

■■Hand type
To engage the parking brake, first apply
the foot brake and then pull up the park-
ing brake lever as far as possible. In addition it is recommended that when
parking the vehicle on an incline, the shift
lever should be in the P (Park) position
for Automatic transaxle, or Reverse for
manual transaxle.Releasing the parking brake
■■Foot type
To release the parking brake, depress
the parking brake pedal a second time
while applying the foot brake. The pedal
will automatically extend to the fully released position.
■■Hand type
To release the parking brake, first apply
the foot brake and pull up the parking
brake lever slightly. Secondly depress the
release button (1) and lower the parking
brake lever (2) while holding the button.
If the parking brake does not release or
does not release all the way, have the
system checked by an authorized
HYUNDAI dealer.

Driving your vehicle
Check the brake warning light by turning
the ignition switch ON (do not start the
engine). This light will be illuminated when
the parking brake is applied with the igni-
tion switch in the START or ON position.
Before driving, be sure the parking brake
is fully released and the brake warning
light is off.
If the brake warning light remains on after
the parking brake is released while the
engine is running, there may be a mal-
function in the brake system. Immediate
attention is necessary.
If at all possible, cease driving the vehi-
cle immediately. If that is not possible,
use extreme caution while operating the
vehicle and only continue to drive the
vehicle until you can reach a safe loca-
tion or repair shop.
Anti-lock brake system (ABS)
W-75
WARNING
To prevent unintentional move- ment when stopped and leaving
the vehicle, do not use the shift
lever in place of the parking
brake. Set the parking brake AND
make sure the shift lever is
securely positioned in P (Park).
Never allow anyone who is unfa- miliar with the vehicle to touch
the parking brake. If the parking
brake is released unintentionally,
serious injury may occur.
All vehicles should always have the parking brake fully engaged
when parking to avoid inadver-
tent movement of the vehicle
which can injure occupants orpedestrians.
WARNING
ABS (or ESC) will not prevent acci-
dents due to improper or danger-
ous driving maneuvers. Even
though vehicle control is improved
during emergency braking, always
maintain a safe distance between
you and objects ahead. Vehicle
speeds should always be reduced
during extreme road conditions.
The braking distance for vehicles
equipped with an anti-lock braking
system (or Electronic Stability
Control System) may be longer
than for those without it in the fol-
lowing road conditions.
During these conditions the vehicle should be driven at reduced speeds:
Rough, gravel or snow-covered roads.
With tire chains installed.
(Continued)
CAUTION
Driving with the parking brakeapplied will cause excessive
brake pad and brake rotor wear.
Do not operate the parking brake while the vehicle is moving exceptin an emergency situation. It coulddamage the vehicle system and make endanger driving safety.

The ABS continuously senses the speed
of the wheels. If the wheels are going to
lock, the ABS system repeatedly modu-
lates the hydraulic brake pressure to the
wheels.
When you apply your brakes under con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
in the brake pedal. This is normal and it
means your ABS is active.
In order to obtain the maximum benefit
from your ABS in an emergency situa-
tion, do not attempt to modulate your
brake pressure and do not try to pump
your brakes. Press your brake pedal as
hard as possible or as hard as the situa-
tion allows the ABS to control the force
being delivered to the brakes.✽✽
NOTICE
A click sound may be heard in the
engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the anti-lock brake system
is functioning properly.
Even with the anti-lock brake system, your vehicle still requires sufficient
stopping distance. Always maintain a
safe distance from the vehicle in front
of you.
Always slow down when cornering. The anti-lock brake system cannot pre-
vent accidents resulting from exces-
sive speeds.
On loose or uneven road surfaces, operation of the anti-lock brake system
may result in a longer stopping dis-
tance than for vehicles equipped with a
conventional brake system.
(Continued)
On roads where the road surfaceis pitted or has different surface height.
The safety features of an ABS (or
ESC) equipped vehicle should not
be tested by high speed driving or
cornering. This could endanger the
safety of yourself or others.

529
Driving your vehicle
✽✽NOTICE
When you jump start your vehicle
because of a drained battery, the engine
may not run as smoothly and the ABS
warning light may turn on at the same
time. This happens because of the low
battery voltage. It does not mean your
ABS is malfunctioning.
 Do not pump your brakes!
 Have the battery recharged before driving the vehicle.
Electronic stability control (ESC)
The Electronic Stability control (ESC)
system is designed to stabilize the vehicle
during cornering maneuvers. ESC checks
where you are steering and where the
vehicle is actually going. ESC applies the
brakes at individual wheels and
intervenes in the engine management
system to stabilize the vehicle.
W-78
CAUTION
If the ABS warning light is on and
stays on, you may have a problemwith the ABS. In this case, howev- er, your regular brakes will worknormally.
The ABS warning light will stay on for approximately 3 seconds after
the ignition switch is ON. Duringthat time, the ABS will go throughself-diagnosis and the light will gooff if everything is normal. If the light stays on, you may have aproblem with your ABS. Contactan authorized HYUNDAI dealer assoon as possible.
CAUTION
When you drive on a road having poor traction, such as an icy road,and have operated your brakes
continuously, the ABS will beactive continuously and the ABSwarning light may illuminate. Pullyour vehicle over to a safe place
and stop the engine.
Restart the engine. If the ABS warning light is off, then your
ABS system is normal. Otherwise, you may have a prob-lem with the ABS. Contact anauthorized HYUNDAI dealer as
soon as possible.

The Electronic Stability Control (ESC) system is an electronic system designed
to help the driver maintain vehicle control
under adverse conditions. It is not a
substitute for safe driving practices.
Factors including speed, road conditions
and driver steering input can all affect
whether ESC will be effective in
preventing a loss of control. It is still your
responsibility to drive and corner at
reasonable speeds and to leave a
sufficient margin of safety.
When you apply your brakes under con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
in the brake pedal. This is normal and it
means your ESC is active.
✽✽
NOTICE
A click sound may be heard in the
engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the Electronic Stability
Control System is functioning properly.

button (ESC OFF indicatorlight will go off).
you may hear a slight ticking
sound. This is the ESC per-
forming an automatic system
self-check and does not indi-
cate a problem.WARNING
Never drive too fast according to
the road conditions or too quickly
when cornering. Electronic stability
control (ESC) will not prevent acci-
dents. Excessive speed in turns,
abrupt maneuvers and hydroplan-ing on wet surfaces can still result
in serious accidents. Only a safe
and attentive driver can prevent
accidents by avoiding maneuvers
that cause the vehicle to lose trac-
tion. Even with ESC installed,
always follow all the normal precau-
tions for driving - including driving
at safe speeds for the conditions.
