Engine power can be delivered to all
front and rear wheels for maximum
traction. AWD is useful when extra
traction is required, 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-
highway that the driver carefully
reduces the speed to a level that
does not exceed the safe operating
speed for those conditions. In gener-
al, off-road conditions provide less
traction and braking effectiveness
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 con-
sidered when driving off-road.
Keeping the vehicle in contact with
the driving surface and under control
in these conditions is always the dri-
ver's responsibility for the safety of
him/herself and his or her passen-
gers.

This mode is used for climbing or descending sharp grades,
off-road driving, driving on sandy and muddy roads, etc., to
maximize traction.
This mode automatically begins to deactivate at speeds above 30 km/h (19 mph) and is shifted to AWD AUTO mode
at speeds above 40 km/h (25 mph). If the vehicle decelerates
to speeds below approximate 40 km/h (25 mph), however,
the transfer mode is shifted into AWD LOCK mode again.

not illuminated)
All Wheel Drive (AWD) transfer mode selection
Transfer mode Selection button Indicator light Description
When driving in AWD AUTO mode, the vehicle operates sim-
ilar to conventional FWD vehicles under normal operating
conditions. However, if the system determines that there is a
need for the AWD mode, the engine’s driving power is dis-
tributed to all four wheels automatically without driver inter-
vention.
When driving on normal roads and pavement, the vehicle moves similar to conventional FWD vehicles.
AWD LOCK (Indicator light isilluminated)
When the AWD LOCK mode is deactivated, a shock may be felt as the drive power is delivered entirely to the front
wheels. This shock is not a mechanical failure.
CAUTION- Normal road conditions
Do not drive on normal roads for prolonged periods of time with your vehicle locked in the AWD mode.Driving on normal road with AWD LOCK Mode (especially, when cornering) may cause mechanical noise orvibration which may damage your power train.

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.

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) (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.

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.

The AEB system is to reduce or to
avoid accident risk. It recognizes the
distance from the vehicle ahead or
the pedestrian through the sensors
(i.e. radar and camera), and, if nec-
essary, warns the driver of accident
risk with the warning message or the
warning alarms.✽ ✽
NOTICE
Take the following precautions when
using the Autonomous Emergency
Braking (AEB):
• This system is only a supplemental
system and it is not intended to,
nor does it replace the need for
extreme care and attention of the
driver. The sensing range and
objects detectable by the sensors
are limited. Pay attention to the
road conditions at all times.
• NEVER drive too fast in accor- dance with the road conditions or
while cornering.
• Always drive cautiously to prevent unexpected and sudden situations
from occurring. AEB does not stop
the vehicle completely and does
not avoid collisions.
System setting and activation
System setting
The driver can activate the AEB by
placing the ignition switch to the ON
position and by selecting 'User
Settings', 'Driving Assist', and 'Assist
Braking System'. The AEB deacti-
vates, when the driver cancels the
system setting.
WARNING
- Autonomous Emergency
Braking (AEB) Limitations
The AEB system is a supple-
mental system and is not a sub-
stitute for safe driving prac-
tices. It is the responsibility of
the driver to always check the
speed and distance to the vehi-
cle ahead to ensure it is safety
to use the AEB system.

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.

The AEB warning message may
appear along with the illumination
of the ESC warning light. The AEB may unnecessarily pro-
duce warning messages and warn-
ing alarms. Due to the sensing lim-
itation, the AEB may not produce
warning messages or warning
alarm at all.
When there is a malfunction with the AEB, the braking control does
not operate upon detecting a colli-
sion risk even with other braking
systems normally operating.
The AEB only operates when it identifies a vehicle/pedestrian in
front of the vehicle while driving
forward. It does not operate when
the vehicle is driving in reverse.
The AEB can not recognize cross- traffic or parked vehicles present-
ing a side-profile.Limitation of the system
The AEB assists the driver in reduc-
ing a specific risk, it does not take
responsibility away from the driver to
control the vehicle in a safe manner.
The AEB monitors the driving situa-
tions through the radar and the cam-
era sensor. For any vehicle activity
occurring outside the sensor range,
the AEB may not function. The driver
should exercise caution in the follow-
ing situations, as the AEB operation
may be limited:
WARNING
The AEB is only a supplemental
system for the driver’s conven-
ience.
The driver still maintains
responsibility to control the
vehicle. Do not solely depend
on the AEB system. Rather,
maintain a safe braking dis-
tance, and, if necessary,
depress the brake pedal to
lower the driving speed.
