AWD AUTO
(AWD LOCK is deactivated) AWD Auto is used when driving on roads in normal conditions, roads in
urban areas, and on highways.
All wheels are in operation when a vehicle travels at a constant speed. Required tractions applying on front and rear wheels vary depending on
road driving conditions and driving conditions, which will be automatically
controlled by the computing system.
When the cluster's AWD Auto display mode is selected, the cluster displays the status of how four wheels’ traction forces are distributed.
AWD LOCK
The main goal of AWD Lock mode is to allow a driver to maximize the vehi- cle’s traction under extreme driving conditions such as unpaved off-road,
sandy roads, and muddy roads.
AWD Lock mode is in operation only when a vehicle travels at 40km/h or less. When travelling at 40km/h or faster, the mode will switch to AWD Auto.
When travelling at 30 km/h or less, the mode will switch back to AWD Lock.
When AWD Lock mode illuminates, the cluster does not display the front/rear wheel traction force distribution status.
Press the AWD Lock mode switch again to switch back to AWD Auto.

✽ ✽NOTICE - Normal road conditions
• Maintain AWD Auto mode when driving on roads in normal conditions.
• When driving under normal road conditions (especially when cornering) in AWD Lock mode, a driver may find
minor mechanical vibration or noise, which is extremely normal phenomenon, not a malfunction. When AWD
Lock mode is released, such noise or vibration will be immediately gone.

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 5 mph (8 km/h).
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.
OUM058053L
WARNING- AWD
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.

525
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
vehicle
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.

539
Driving your vehicle
If there is a malfunction with the dri-
ver’s door, engine hood or trunk open
detection system, the Auto Hold may
not work properly.
Take your vehicle to an authorized Kia
dealer and have the system checked.
✽ ✽NOTICE
A click or electric brake motor
whine sound may be heard while
operating or releasing the EPB, but
these conditions are normal and
indicate that the EPB is functioning
properly.
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.WARNING
To reduce the risk of an acci-
dent, do not activate Auto Hold
while driving downhill, backing
up or parking your vehicle.

541
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 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 mal-
functioned.
• 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 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.

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 opera-
tion.
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
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
goes out.
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 two surface road. The two sur-
face road is made of surfaces
which have different 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.
