Driving your vehicle
For safe all wheel drive opera-
tion
Do not try to drive in deep standingwater or mud since such conditions
can stall your engine and clog your
exhaust pipes. Do not drive down
steep hills since it requires extreme
skill to maintain control of the vehi-
cle.
When you are driving up or downhills; drive as straight as possible.
Use extreme caution going up or
down steep hills, the grade, terrain
and water/mud conditions may
cause the vehicle to flip.
HILL1HILL2
WARNING-Hills
Proceed with extreme caution
when driving down steep hills.
A slight change in the wheel
angle can destabilize the vehi-
cle. This can cause your vehicle
to suddenly roll without warn-
ing and without time for you to
regain control of your vehicle.

You must consciously take the
effort to learn how to corner in a
AWD vehicle. Do not rely on your
experience in conventional FWD
vehicles in choosing a safe corner-
ing speed in AWD mode. For
starters, you must drive more slow-
ly in AWD.
Drive carefully off-road because your vehicle may be damaged by
rocks or roots of trees. Become
familiar with the off-road conditions
where you are going to drive
before you begin driving. Always hold the steering wheel
firmly when you are driving off-
road.
Make sure all passengers are wearing seat belts.
If you need to drive in the water, stop your vehicle, set your transfer
to the AWD LOCK mode and drive
at less than 8 km/h (5 mph).
WARNING- Steering
wheel
Do not grab the inside of the
steering wheel when you are
driving off-road. You may hurt
your arm by a sudden steering
maneuver or from steering
wheel rebound due to impact
with objects on the ground.
WARNING-Wind danger
Drive slowly in heavy winds.
The vehicle's higher center of
gravity decreases your steering
control capacity.
WARNING -AW D
Reduce speed when you turn
corners. The center of gravity of
AWD vehicles is higher than
that of conventional FWD vehi-
cles, making them more likely to
roll over when you turn corners
too fast.

Driving your vehicle
✽ ✽NOTICE
• 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 section
7). Always wash your vehicle thor-
oughly after off-road use, especial-
ly cleaning the bottom of the vehi-
cle.
• A full time all 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.
Do not use a tire and wheel package
with a different size and type from
the one originally installed on your
vehicle. It can affect the safety and
performance of your vehicle, which
could lead to steering failure or
rollover causing 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 equip your vehicle with any
tire/wheel combination not recom-
mended by Kia for off-road driving,
ou should not use thesetires for high
way driving.
CAUTION - Mud or snow
Do not run the engine continu-
ously at high RPMs to free thevehicle from snow or mud. Doingso could damage the AWD sys-tem in your vehicle.
WARNING- AWD driving
Do not attempt quick steering
maneuvers or sharp turns in
AWD mode. Such maneuvers
increase the risk of rollover
accidents. Rollover accidents
are extremely violent and
unpredictable.WARNING -Driving
through water
Drive slowly. If you are driving
too fast in water, the water can
get into the engine compartment
and wet the ignition system,
causing your vehicle to sudden-
ly stop. If this happens and your
vehicle is in a tilted position,
your vehicle may roll over.

Full-time AWD vehicles must be
tested on a special four wheel
chassis dynamometer.
A full-time AWD vehicle should not be tested on a FWD roll tester. If a
FWD roll tester must be used, per-
form the following: 1. Check the tire pressures recom-
mended 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 tem- porary free roller as shown in the
illustration.
WARNING- Jacked vehi-
cle
While the full-time AWD vehicle
is being raised on a jack, never
start the engine or cause the
tires to rotate.
There is the danger that rotating
tires touching the ground could
cause the vehicle to go off the
jack and to jump forward.

WARNING- Replacement Tires
When replacing tires and
wheels, be sure all four tires are
the same size, type, tread and
have the same load-carrying
capacity as the original equip-
ment tires. Installing replace-
ment tires that vary from the
original equipment tires can
negatively effect vehicle han-
dling and can increase the risk
of an accident.

Anti-lock brake system (ABS)
ABS (or ESC) will not prevent acci-
dents due to improper or dangerous
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 vehicle
should be driven at reduced speeds
in the following circumstances:
When driving on rough, gravel or
snow-covered roads.
When driving on roads where the road surface is pitted or has differ-
ent surface heights.
Driving in these conditions increase
the stopping distance for your vehi-
cle. The ABS continuously senses the
speed of the wheels. If the wheels
are going to lock, the ABS system
repeatedly modulates the hydraulic
brake pressure to the wheels.
When you apply your brakes under
conditions which may lock the
wheels, you may hear a “tik-tik’’
sound from the brakes, or feel a cor-
responding sensation in the brake
pedal. This is normal and it means
your ABS is active.
In order to obtain the maximum ben-
efit from your ABS 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 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 vehi-
cle begins to move after the engine is
started. These conditions are normal
and indicate that the anti-lock brake
system is functioning properly.

Electronic stability control
(ESC)
The Electronic Stability control
(ESC) system is designed to stabi-
lize the vehicle during cornering
maneuvers. ESC checks where you
are steering and where the vehicle is
actually going. ESC applies the
brakes on individual wheels and
intervenes with the engine manage-
ment system to stabilize the vehicle. Electronic stability control (ESC) will
not prevent accidents. Excessive
speed in turns, abrupt maneuvers
and hydroplaning 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 traction. Even with ESC
installed, always follow all the normal
precautions for driving - including
driving at safe speeds for the condi-
tions.
The Electronic Stability Control (ESC)
system is an electronic system
designed to help the driver maintain
vehicle control under adverse condi-
tions. It is not a substitute for safe driv-
ing 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
conditions which may lock the wheels,
you may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensa-
tion 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 vehi-
cle begins to move after the engine is
started. These conditions are normal
and indicate that the Electronic
Stability Control System is function-
ing properly.

Vehicle stability management
(VSM)
This system provides further
enhancements to vehicle stability
and steering responses when a vehi-
cle is driving on a slippery road or a
vehicle detects changes in coeffi-
cient of friction between right wheels
and left wheels when braking.
VSM operation
When the VSM is in operation, ESC
indicator light ( ) blinks.
When the vehicle stability manage-
ment is operating properly, you can
feel a slight pulsation in the vehicle
and/or abnormal steering responses
(EPS). This is only the effect of brake
and EPS control and indicates noth-
ing unusual.
The VSM does not operate when:
Driving on bank road such as gra-
dient or incline
Driving in reverse
ESC OFF indicator light ( ) remains on the instrument cluster
EPS indicator light remains on the instrument cluster
VSM operation off
If you press the ESC OFF button to
turn off the ESC, the VSM will also
cancel and the ESC OFF indicator
light ( ) illuminates.
To turn on the VSM, press the button
again. The ESC OFF indicator light
goes out.
WARNING- Tire/
Wheel size
When replacing tires and
wheels, make sure they are the
same size as the original tires
and wheels installed. Driving
with varying tire or wheel sizes
may diminish any supplemental
safety benefits of the VSM sys-
tem.

Driving your vehicle
Malfunction indicator
The VSM can be deactivated even if
you don’t cancel the VSM operation
by pressing the ESC OFF button. It
indicates that a malfunction has
been detected somewhere in the
Electric Power Steering system or
VSM system. If the ESC indicator
light ( ) or EPS warning light
remains on, take your vehicle to an
authorized Kia dealer and have the
system checked.
✽ ✽NOTICE
• The VSM is designed to function
above approximately 22 km/h (13
mph) on curves.
• The VSM is designed to function above approximately 10 km/h (6
mph) when a vehicle is braking on
a split-mu road. The split-mu road
is made of surfaces which have dif-
ferent friction forces.
The Vehicle Stability Management
system is not a substitute for safe
driving practices but a supplemen-
tary function only. It is the respon-
sibility of the driver to always check
the speed and the distance to the
vehicle ahead. Always hold the
steering wheel firmly while driving.
Your vehicle is designed to activate according to the driver’s intention,
even with installed VSM. Always
follow all the normal precautions
for driving at safe speeds for the
conditions – including driving in
clement weather and on a slippery
road.Hill-start assist control (HAC)
A vehicle has the tendency to roll
back on a steep hill when it starts to
go after stopping. The Hill-start
Assist Control (HAC) prevents the
vehicle from rolling back by applying
the brakes automatically for about 2
seconds. The brakes are released
when the accelerator pedal is
depressed or after about 2 seconds.
The HAC is activated only for about 2
seconds, so when the vehicle is
starting off always depress the accel-
erator pedal.
WARNING- Maintaining
Brake Pressure on Incline
HAC does not replace the need
to apply brakes while stopped
on an incline. While stopped,
make sure you maintain brake
pressure sufficient to prevent
your vehicle from rolling back-
ward and causing an accident.
Don’t release the brake pedal
until you are ready to accelerate
forward.

Good braking practices
Check to be sure the parking brake
is not engaged and the parking
brake indicator light is out before
driving away.
Driving through water may get the brakes wet. They can also get wet
when the vehicle is washed. Wet
brakes can be dangerous! 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 call an
authorized Kia dealer for assis-
tance. Don't coast down hills with the
vehicle out of gear. This is extreme-
ly hazardous. Keep the vehicle in
gear at all times, use the brakes to
slow down, then shift to a lower
gear so that engine braking will
help you maintain a safe speed.
Don't "ride" the brake pedal. Resting your foot on the brake
pedal while driving can be danger-
ous because the brakes might
overheat and lose their effective-
ness. It also increases the wear of
the brake components.
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 place. If your vehicle is equipped with an
automatic transaxle, don't let your
vehicle creep forward. To avoid
creeping forward, keep your foot
firmly on the brake pedal when the
vehicle is stopped.
Be cautious when parking on a hill. Firmly engage the parking brake
and place the shift lever in P (auto-
matic transaxle). If your vehicle is
facing downhill, turn the front
wheels into the curb to help keep
the vehicle from rolling. If your vehi-
cle is facing uphill, turn the front
wheels away from the curb to help
keep the vehicle from rolling. If
there is no curb or if it is required
by other conditions to keep the
vehicle from rolling, block the
wheels.

549
Driving your vehicle
Under some conditions your park-ing brake can freeze in the
engaged position. This is most like-
ly to happen when there is an
accumulation of snow or ice
around or near the rear brakes or if
the brakes are wet. If there is a risk
that the parking brake may freeze,
apply it only temporarily while you
put the shift lever in P (automatic
transaxle) and block the rear
wheels so the vehicle cannot roll.
Then release the parking brake.
Do not hold the vehicle on the upgrade with the accelerator
pedal. This can cause the transaxle
to overheat. Always use the brake
pedal or parking brake.
