Moving up a steep grade from a stand-
ing start
To move up a steep grade from a stand-
ing start, depress the brake pedal, shift
the shift lever to D (Drive). Select the
appropriate gear depending on load
weight and steepness of the grade, and
release the parking brake. Depress the
accelerator gradually while releasing the
service brakes.
When accelerating from a stop on a
steep hill, the vehicle may have a ten-
dency to roll backwards. Shifting the
shift lever into 2 (Second Gear) will
help prevent the vehicle from rolling
backwards.
WARNING
If your vehicle becomes stuck in
snow, mud, sand, etc., then you
may attempt to rock the vehicle free
by moving it forward and backward.
Do not attempt this procedure if
people or objects are anywhere
near the vehicle. During the rocking
operation the vehicle may suddenly
move forward of backward as it
becomes unstuck, causing injury
or damage to nearby people orobjects.WARNING
Always buckle-up! In a collision, an unbelted occupant is signifi-
cantly more likely to be seriously
injured or killed than a properlybelted occupant.
Avoid high speeds when corner- ing or turning.
Do not make quick steering wheel movements, such as sharp
lane changes or fast, sharp turns.
The risk of a rollover is greatly increased if you lose control of
your vehicle at highway speeds.
Losing control often occurs if two or more wheels drop off the road-
way and the driver oversteers 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.
Never exceed posted speed lim- its.

FOUR WHEEL DRIVE (4WD) (IF EQUIPPED)
Engine power can be delivered to all front
and rear wheels for maximum traction.
4WD is useful when extra traction is
required on road, such as, when driving
on slippery, muddy, wet, or snow-covered
roads. These vehicles are not designed
for challenging off-road use. Occasional
off-road use such as established
unpaved roads and trails are OK. It is
always important when traveling off-high-
way that the driver carefully reduces the
speed to a level that does not exceed the
safe operating speed for those condi-
tions. In general, off-road conditions pro-
vide less traction and braking effective-
ness than normal road conditions. The
driver must be especially alert to avoid
driving on slopes which tilt the vehicle to
either side.
These factors must be carefully consid-
ered when driving off-road. Keeping the
vehicle in contact with the driving surfaceand under control in these conditions is
always the driver's responsibility for the
safety of him/herself and his or her pas-
sengers. Tight corner brake effect
Tight corner brake effect is a unique
characteristic of four-wheel drive vehicles
caused by the difference in tire rotation at
the four wheels and the zero-degreealignment of the front wheels and sus-pension.
Sharp turns at low speeds should be car-
ried out with caution.
WARNING
- Off road driving
This vehicle is designed primarily
for on road use although it can oper-
ate effectively off road. However, it
was not designed to drive in chal-
lenging off-road conditions. Driving
in conditions that exceed the vehi-
cle's intended design or the driver's
experience level may result in
severe injury or death.
CAUTION - 4WD
When turning sharply on a paved
road at low speed while in four-wheel drive, steering control will be difficult.

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 4WD 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
vehicles are designed to perform satis-
factorily in off-road conditions. Due to this
risk, driver and passengers are strongly
recommended 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 at
high rpm because doing so coulddamage the 4WD system.
WARNING - 4WD 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 aseat 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.

529
Driving your vehicle
Full-time 4WD vehicles must be testedon a special four wheel chassis
dynamometer.
✽✽ NOTICE
Never engage the parking brake while
performing these tests.
A full-time 4WD 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.

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.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 increasedstopping distances.
When descending a long or steep hill, shift to a lower gear and
avoid continuous application of
the brakes. Continuous brakeapplication 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 oneside 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 performancereturns to normal.
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.

Disc brakes wear indicator
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 (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 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.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 a low gear on manual
transaxle vehicles or in the P (Park) posi-
tion on automatic transaxle vehicles.
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 aserious accident.
CAUTION
To avoid costly brake repairs, do not continue to drive with worn
brake pads.
Always replace the front or rear brake pads as pairs.
OXM059013OXM059015
CAUTION
Driving with the parking brake
applied will cause excessive brakepad and brake rotor wear.

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 fullyreleased 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 KIA
dealer.
WARNING
To prevent unintentional move- ment when stopped and leaving
the vehicle, do not use the shift
lever instead of the parking
brake. Set the parking brake AND
make sure the shift lever is
securely positioned in 1st (First)
gear or R (Reverse) for manual
transaxle equipped vehicles and
in P (Park) for automatic
transaxle equipped vehicles.
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.

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)
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.
WARNING
ABS (or ESP) 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 vehicle
equipped with an anti-lock braking
system (or Electronic Stability
Program System) may be longer
than for those without it in the fol-
lowing road conditions.
During these conditions the vehicle should be driven at reducedspeeds:
Rough, gravel or snow-covered roads.
With tire chains installed. (Continued)
(Continued)
On roads where the road surfaceis pitted or has different surface height.
The safety features of an ABS (or
ESP) equipped vehicle should not
be tested by high speed driving or
cornering. This could endanger the
safety of yourself or others.

✽✽
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.
✽✽ 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 low bat-
tery voltage. It does not mean your ABS
has malfunctioned.
 Do not pump your brakes!
 Have the battery recharged before driving 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 work normally.
The ABS warning light will stay on for approximately 3 seconds afterthe ignition switch is ON. Duringthat time, the ABS will go throughself-diagnosis and the light will go off if everything is normal. If thelight stays on, you may have aproblem with your ABS. Contactan authorized KIA dealer as soonas 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. Pull
your vehicle over to a safe placeand stop the engine.
Restart the engine. If the ABS warning light goes off, then your
ABS system is normal. Otherwise, you may have a prob-lem with the ABS. Contact an authorized KIA dealer as soon as
possible.

Driving your vehicle
Electronic stability program (ESP) (If equipped)
The Electronic Stability Program (ESP)
system is designed to stabilize the vehicle
during cornering maneuvers. ESP checks
where you are steering and where the
vehicle is actually going. ESP applies the
brakes on individual wheels and
intervenes with the engine management
system to stabilize the vehicle.The Electronic Stability Program (ESP)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 ESP 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 ESP 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
Program System is functioning proper-
ly.
WARNING
Never drive too fast according to
the road conditions or too quickly
when cornering. Electronic stability
program (ESP) 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 ESP installed,
always follow all the normal precau-
tions for driving - including driving
at safe speeds for the conditions.
