Driving your vehicle
If you need to drive in water, stop yourvehicle, set your transfer knob to 4LO
or LOW and drive at less than 8 km/h
(5 mph). Do not drive in water if the level is high-
er than the bottom of the wheel hubs.
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 off-road in condi-
tions such as sand, mud or water (see
“Scheduled Maintenance’’ in the
Index). Always wash your car thor-
oughly.
The full time four wheel drive vehicle cannot be towed by an ordinarily tow
truck. Make sure that the vehicle is
towed with its four wheels raised off the
ground.
Since the driving torque is always applied to the 4 wheels the perform-
ance of the 4WD vehicle is greatly
affected by the condition of the tires.
Be sure to equip them with all four tires
with same size and type.
WARNING
If you are driving in heavy wind, the
vehicle’s higher center of gravity
decreases your steering control.
Drive more slowly than you would
in calm conditions.
WARNING
- Drivingthrough water
If you are driving too fast in water,
the water spray can get into the
engine compartment and wet the
ignition system, causing your vehi-
cle to suddenly stop. If this hap-
pens and your vehicle is in a tilted
position, your vehicle may roll over.
WARNING
Your vehicle is equipped with tires
designed to provide for safe ride
and handling capability.
Do not use a size and type of tire
and wheel that is different from the
one that is originally installed on
your vehicle. It can affect the safety
and performance of your vehicle,
which could lead to handling failure
or rollover and serious injury.
When replacing the tires, be sure to
equip all four tires with the tire and
wheel of the same size, type, tread,
brand and load-carrying capacity. If
you nevertheless decide to equip
your vehicle with any tire/wheel
combination not recommended by
Kia for off road driving, you should
not use these tires for highway driv-
ing.

4 For speedometer test or inspection/
maintenance (I/M) program of full-time
4WD vehicle, use a four wheel chassis
dynamometer. A 4WD vehicle should not be tested on
a 2WD drive roll tester. If a 2WD roll
tester must be used, perform the fol-
lowing:
1. Check the tire pressures recommend- ed for your vehicle.
2. Place the rear wheels on the roll tester for speedometer test as shown in the
illustration.
3. Release the parking brake.
4. Place the front wheels on the tempo- rary free roller as shown in the illustra-
tion.
E5BLA401
Roll tester (speedometer) Temporary free roller
CAUTION
Never engage the parking brake
while performing these tests.
CAUTION
While the full-time 4WD vehicle isbeing raised on a jack, never start the engine or cause the tires torotate.
There is the danger that rotatingtires touching the ground couldcause the vehicle to go off the jack and to jump forward.
If one of the front or rear wheelsbegins to spin in mud, snow, etc.the vehicle can sometimes be driv-en out by depressing the accelera- tor pedal further; however avoidrunning the engine continuously at high rpm because doing so coulddamage the 4WD system.
WARNING
Keep away from the front of the
vehicle while inspecting. This is
very dangerous as the vehicle can
jump forward and cause serious
injury or death.

419
Driving your vehicle
A limited slip differential if equipped, is for
the rear wheel differential only. The fea-
tures of this limited slip differential are
described below;
Just as with conventional differential, the
wheel on one side is allowed to turn at a
different speed from the wheel on the
other side when the vehicle is cornering.
The difference between the limited slip
differential and a conventional differential
is that if the wheel on one side of the
vehicle loses traction, a greater amount
of torque is applied to the rear wheel on
the other side to improve traction.
WARNING
To avoid injury, never run the
engine with one wheel off the
ground, such as when changing a
tire.
WARNING
Avoid high cornering speed.
Do not make quick steering wheelmovements, 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 speeds.
In a collision crash, 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.
LIMITED SLIP DIFFERENTIAL (IF EQUIPPED)

Driving your vehicle20
4Power 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 somewhat 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.
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.
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 increased
stopping 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 result in the vehi- cle not slowing down at the usual
rate and pulling to one side when
the brakes are applied. After
going through water, apply the
brakes lightly to regain smooth
braking performance.
WARNING
- Parking brake
Operating the parking brake while
the vehicle is moving at normal
speeds can cause a sudden loss of
control of the vehicle. If you must
use the parking brake to stop the
vehicle, use great caution in apply-
ing the brake.

Driving your vehicle
Disc brakes wear indicator Your vehicle has disc brakes.
When your brake pads are worn and it's
time for new pads, you will hear a high-
pitched warning sound from your front
brakes or rear brakes (if equipped). You
may hear this sound come and go or it
may occur whenever you depress the
brake pedal.
Please remember that some driving
conditions or climates may cause a
brake squeal when you first apply (or
lightly apply) the brakes. This is nor-
mal and does not indicate a problem
with your brakes.
✽ ✽NOTICETo avoid costly brake repairs, do not
continue to drive with worn brake pads.
Parking brake To apply the parking brake, pull the park-
ing brake handle fully and firmly upward
while applying the service brake.
WARNING
- Brake wear
This brake wear warning sound
means your vehicle needs service.
If you ignore this audible warning,
you will eventually lose braking per-
formance, which could lead to a
serious accident.
CAUTION
Always replace brake pads as com-
plete front or rear axle sets toensure smooth brake performance.
E2BLA416Z
CAUTION
Driving with the parking brakeapplied will cause excessive brake pad and brake rotor wear.

Driving your vehicle22
4To release the parking brake, pull the
handle up slightly and push the release
button, then lower the handle to the
released position while holding the but-
ton in. 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 ignition 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, there
may be a malfunction in the brake sys-
tem. 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.
WARNING
- Parking brake
To prevent unintentional move-
ment when stopped, do not use
just the gear shift lever to hold
the vehicle in position. Set the
parking brake AND make sure the
gearshift lever is securely posi-
tioned in 1st (First) gear or R
(Reverse) for manual transmis-
sion equipped vehicles and in P
(Park) for automatic transmission
equipped vehicles.
Never allow a person who is unfa- miliar with the vehicle or children
to touch the parking brake. If the
parking brake is released unin-
tentionally, serious injury may
occur.

423
Driving your vehicle
Parking on curbed streets When parking your vehicle on an uphillgrade, park as close to the curb as
possible and turn the front wheels
away from the curb so that the front
wheels will contact the curb if the vehi-
cle moves backward.
When parking your vehicle on a down- hill grade, park as close to the curb as
possible and turn the front wheels
toward the curb so that the front
wheels will contact the curb if the vehi-
cle moves forward.
Anti-lock brake system (ABS)
(if equipped)
The ABS system continuously senses
the speed of the wheels. If the wheels are
going to lock, the ABS system repeated-
ly modulates the hydraulic brake pres-
sure 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 system is active.
In order to obtain the maximum benefit
from your ABS system in an emergency
situation, 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 situation warrants and allow the ABS
system to control the force being deliv-
ered to the brakes.
WARNING
- ABS Brakes
Your ABS is not a substitute for
good driving judgement. You can
still have an accident. In fact, your
ABS system will not be able to pre-
vent an accident. You must espe-
cially avoid:
Dangerous driving, such asneglecting safety precautions,
speeding, or driving too close to
the vehicle in front of you.
Driving at high speed in situa- tions providing considerably less
traction, such as wet conditions
where hydroplaning could occur.
Driving too fast on poor road sur- faces. The ABS is designed to
improve maximum braking effec-
tiveness on typical highways and
roads in good condition. On poor
road surfaces, the ABS may actu-
ally reduce braking effectiveness.

Driving your vehicle24
4 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.
✽ ✽ NOTICEWhen 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.
ABS
W-78
CAUTION
If the ABS warning light is on and
stays on, you may have a problemwith the ABS system. In this case,however, your regular brakes will work normally.
The ABS warning light will stay on for approximately 3 secondsafter the ignition switch is ON. During that time, the ABS will gothrough self-diagnosis and the light will go off if everything isnormal. If the light stays on, you may have a problem with yourABS system. Contact an author-ized Kia dealer as soon as possi-ble.
CAUTION
When you drive on a road having poor traction, such as an icy road,and operate your brakes continu-ously, the ABS will be active con-tinuously and the ABS warning light may illuminate. Pull your carover to a safe place and stop theengine.
Restart the engine. If the ABS warning light is off, then yourABS system is normal. Otherwise, you may have a prob-lem with the ABS. Contact anauthorized Kia dealer as soon as possible.
