you only have two tire chains,
install them on the rear tires. In
this situation, do not drive more
than a short distance to prevent
damage to the AWD system.
• If tire chains must be used, use an AutoSock (fabric snow chain) and
install the tire chain after review-
ing the instructions provided with
the tire chains.
❈ ❈ For more information on Snow
Tires and Tire Chains, refer to

Driving up or down hills
Driving uphill
- Before starting off, check if it ispossible to drive uphill.
- Drive as straight as possible.
Driving downhill - Do not change gear while drivingdownhill. Select gear before driv-
ing downhill.
- Drive slowly using engine braking while driving downhill.
- Drive as straight as possible.Emergency precautions
Tires
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.
In case of emergency such as tire
puncture, repair it using the TMK
(Tire Mobility Kit) for temporary use.
Afterwards, have the tire be inspect-
ed by an authorized K900 Kia dealer.WARNING
Exercise extreme caution driv-
ing up or down steep hills. The
vehicle's tires could lose trac-
tion depending on the grade,
terrain and water/mud condi-
tions.
WARNING
Do not use tires and wheels of a
different size and type than the
ones originally installed on your
vehicle. It can affect the safety
and performance of your vehi-
cle, which could lead to
increased steering difficulty or
rollover, causing serious injury.

wheel lift and dollies or flatbed equip-
ment with all the wheels off the
ground. For more information, refer
to “Towing” in chapter 6.
Vehicle inspection
When the vehicle is on a car lift, donot operate the front and rear
wheels separately. All four wheels
should be operated.
Never engage the parking brake while running the engine on a car
lift. This may damage the AWD
system.WARNING
Never start or run the engine
while an AWD vehicle is raised
on a jack. The vehicle can slip or
roll of the jack, causing serious
injury or death to you or those
nearby.

Dynamometer testing
An AWD vehicle must be tested on a
special four wheel chassis
dynamometer.
An AWD vehicle should not be tested
on a 2WD roll tester. If a 2WD roll
tester must be used, perform the fol-
lowing procedure: 1. Check the tire pressures recom-
mended for your vehicle.
2. Place the rear wheels on the roll tester for a speedometer test as
shown in the illustration.
3. Release the parking brake.
4. Place the front wheels on the tem- porary free roller as shown in the
illustration.
WARNING
Keep away from the front of the
vehicle while the vehicle is in
gear on the dynamometer. The
vehicle can jump forward and
cause serious injury or death.

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 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 to allow 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.
Even with the anti-lock brake sys-
tem, your vehicle still requires suf-
ficient 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
prevent accidents resulting from
excessive speeds.
On loose or uneven road surfaces, operation of the anti-lock brake
system may result in a longer stop-
ping distance than for vehicles
equipped with a conventional
brake system. The ABS warning light will stay on for
approximately 3 seconds after the
ignition switch is ON. During that
time, the ABS will go through self-
diagnosis and the light will go off if
everything is normal. If the light stays
on, you may have a problem with
your ABS. Contact an authorized
K900 Kia dealer as soon as possible.

Driving your vehicle
When you drive on a road havingpoor traction, such as an icy road,
and have operated your brakes
continuously, the ABS will be active
continuously and the ABS warning
light may illuminate. Pull your vehi-
cle over to a safe place and stop
the engine.
Restart the engine. If the ABS warning light goes off, then your
ABS system is normal. Otherwise,
you may have a problem with the
ABS. Contact an authorized K900
Kia dealer as soon as possible.
✽ ✽ 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 battery voltage. It does not
mean your ABS has malfunctioned.
• Do not pump your brakes!
• Have the battery recharged before
driving the vehicle.
Electronic Stability Control
(ESC) system
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 on
individual wheels and intervenes
with the engine management system
to stabilize the vehicle. Electronic Stability Control (ESC)
system 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 conditions.
WARNING
For maximum protection, always
wear your seat belt. No system,
no matter how advanced, can
compensate for all driver error
and/or driving conditions.
Always drive responsibly.

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 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.

Driving your vehicle
✽ ✽NOTICE
• When operating the vehicle on a
dynamometer, ensure that the
ESC is turned off (ESC OFF light
illuminated). If the ESC is left on,
it may prevent the vehicle speed
from increasing, and result in false
diagnosis.
• Turning the ESC off does not affect ABS or brake system operation.
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 the right
wheels and left wheels when brak-
ing.
VSM operation
When the VSM is in operation, the
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- Electronic Power Steering).
This is only the effect of brake and
EPS control and indicates nothing
unusual.
The VSM does not operate when:
Driving on a sloping road such as a
gradient or incline
Driving in reverse
ESC OFF indicator light ( ) remains on the instrument cluster
EPS indicator light remains on the instrument cluster
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 system.

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
will turn off.
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 K900 Kia dealer and have
the system checked.
✽ ✽
NOTICE
• The VSM is designed to function
above approximately 13 mph (22
km/h) on curves.
• The VSM is designed to function above approximately 6 mph (10
km/h) when a vehicle is braking on
a split-mu surface. A split-mu sur-
face is made of two surfaces which
have different friction forces.
The Vehicle Stability Management
system is not a substitute for safe
driving practices but a ssupple-
mental function only. It is the
responsibility 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 fol-
low all the normal precautions for
driving at safe speeds for the condi-
tions - including driving in inclement
weather and on a slippery road.
WARNING
For maximum protection, always
wear your seat belt. No system,
no matter how advanced, can
compensate for all driver error
and/or driving conditions.
Always drive responsibly.
WARNING- Vehicle stabili-
ty management
Drive carefully even though your
vehicle has Vehicle stability man-
agement. It can only assist you in
maintaining control under cer-
tain circumstances.

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 Transmission, 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 transmission). If your vehicle
is facing downhill, turn the front
wheels into the curb to help keep
the vehicle from rolling. If your vehicle 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, chock
the wheels.
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
transmission) and chock the rear
wheels so the vehicle cannot roll.
Then release the parking brake.
Do not hold the vehicle on an incline with the accelerator pedal.
This can cause the transmission to
overheat. Always use the brake
pedal or parking brake.Electronic Control Suspension
(ECS) (if equipped)
The Electronic Control Suspension
(ECS) controls the vehicle suspen-
sion automatically to maximize driv-
ing comfort by taking into account
the driving conditions such as speed,
surface of the road, cornering, stop-
ping requirements and acceleration.
If the ECS warning message “Check
ECS” comes on, you may have a
problem with the ECS system. If this
occurs, have the vehicle inspected
by an authorized K900 Kia dealer
immediately.
