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.
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.

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. 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- Jackedvehicle
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.

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 normally would. The
stopping distance, however, 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
necessary to maintain steering con-
trol on slippery surfaces.Wet brakes may impair the vehicle’s
ability to safely slow down; the vehi-
cle may also pull to one side 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 fash-
ion after driving through deep water.
To dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
BRAKE SYSTEM
WARNING- Steep hill
braking
Avoid continuous application of
the brakes when descending a
long or steep hill by shifting to a
lower gear. Continuous brake
application will cause the brakes
to overheat and could result in a
temporary loss of braking per-
formance.
CAUTION- Brake Pedal
Do not drive with your foot rest- ing on the brake pedal. This willcreate abnormally high braketemperatures which can causeexcessive brake lining and padwear.

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) (if equipped)
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.

Prerequisite for activation
The AEB will activate when the AEB
is selected on the LCD display, and
when the following prerequisites are
satisfied:
- The ESC (Electronic Stability
Control) is activated.
- The driving speed is over 6 mph. (The AEB only works within a cer-
tain range of vehicle speeds)
- When the AEB recognizes a vehi- cle or the pedestrian in front. (The
AEB may not recognize every
obstacle or provide warnings and
braking in every situation, so do
not rely on the AEB to stop the
vehicle in instances where the driv-
er sees an obstacle and has the
ability to apply the brakes) The AEB automatically activates
when you turn the vehicle on.
The driver can deactivate the AEB
by canceling it the system setting on
the LCD display.
Even when the Autonomous Emergency Braking (AEB) may be
set to "Use AEB" setting, if the
Traction Control System (TCS) or
Electronic Stability Control (ESC)
features are deselected, AEB func-
tion will be turned off automatically.
In this case, the AEB feature can-
not be turned on manually as well.
AEB warning message and
system control
Warning text may appear or warning
sound may sound when the vehicle in
front brakes suddenly or the distance
with the vehicle in front is short. Also,
the brake system will control the
brakes depending on the collision
possibility.
Depending on the vehicle condition
and traffic conditions in front of the
vehicle, some warning features may
activate or not activate at all.
WARNING
Set or cancel AEB with control-
ling switches on steering wheel
after stopping the vehicle in the
safe place for your safety.
Do not attempt to set or cancel
the AEB while your vehicle is
moving.

Brake operation
In an urgent situation, the braking
system enters into the ready status
for prompt reaction against the dri-
ver’s depressing the brake pedal.
The AEB provides additional brak- ing power for optimum braking per-
formance, when the driver
depresses the brake pedal.
The braking control is automatical- ly deactivated, when the driver
sharply depresses the brake pedal,
or when the driver abruptly turns
the steering wheel.
The braking control is automatical- ly canceled, when risk factors dis-
appear.
The driver should always exercise
caution when operating the vehicle,
even though there is no warning
message or warning alarm.
✽ ✽ NOTICE
The AEB operates in accordance
with the risk levels, such as the dis-
tance from the vehicle/passer-by in
front, the speed of the vehicle/pass-
er-by in front, and the driver's vehi-
cle operation. Do not drive danger-
ously in order to activate to system.
Sensor to detect the distance
from the vehicle in front
(front radar)
The sensor cannot maintain proper
distance from the vehicle in front
when the sensor lens is obscured by
foreign substances, such as snow
and rain, which will adversely affect
performance. It may even temporarily
cancel the AEB. Always keep the sen-
sor clean.
WARNING
The AEB cannot avoid all colli-
sions. The AEB might not com-
pletely stop the vehicle before
collision, due to ambient weath-
er and road conditions. The
driver has the responsibility to
drive safely and control the
vehicle.

Vehicle recognition
Some vehicles ahead in your lane
cannot be recognized by the sensor
as follows:
- Narrow vehicles such as motorcy-
cles or bicycles
- Vehicles offset to one side
- Slow-moving vehicles or sudden- decelerating vehicles
- Stopped vehicles
- Vehicles with small rear profile such as trailers with no loads A vehicle ahead cannot be recog-
nized correctly by the sensor if any of
following occurs:
- When the vehicle is pointing
upwards due to overloading in the
trunk
- While making turns by steering
- When driving to one side of the lane
- When driving on narrow lanes or on curves
Adjust your vehicle speed by
depressing the brake pedal accord-
ing to the road condition ahead and
driving condition. When vehicles are at a standstill
and the vehicle in front of you
changes to the next lane, be care-
ful when your vehicle starts to
move because it may not recog-
nize the stopped vehicle in front of
you.
