WARNING
If your vehicle becomes stuck in
snow, mud, sand, etc., then you
may attempt to rock the vehicle
free by moving it forward and
backward. Do not attempt this
procedure if people or objects
are anywhere near the vehicle.
During the rocking operation,
the vehicle may suddenly move
forward or backward as it
becomes unstuck, causing
injury or damage to nearby peo-
ple or objects.
Moving up a steep grade from a
standing start
To move up a steep grade from a
standing start, depress the brake
pedal, release the parking brake,
and shift the shift lever to D (Drive).
Select the appropriate gear depend-
ing on load weight and steepness of
the grade, and release the parking
brake. Depress the accelerator grad-
ually while releasing the service
brakes.
When accelerating from a stop on a
steep hill, the vehicle may have a
tendency to roll backwards.
Shifting the shift lever into 2
(Second Gear) will help prevent the
vehicle from rolling backwards.

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 aroud
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 (Intelligent
Variable Transmission) and chock
the rear wheels so the vehicle can-
not 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. Check the brake warning light by
turning the ignition switch or
ENGINE START/STOP button ON
(do not start the engine). This light
will illuminate when the parking
brake is applied with the ignition
switch or ENGINE START/STOP but-
ton in the START or ON position.
Before driving, be sure the parking
brake is fully released and the brake
warning light is off.
If the brake warning light remains on
after the parking brake is released
while the engine is running, there
may be a malfunction in the brake
system. Immediate attention is nec-
essary. If at all possible, stop driving the
vehicle immediately. If that is not pos-
sible, use extreme caution while
operating the vehicle and only con-
tinue to drive the vehicle until you
can reach a safe location or repair
shop.

Anti-lock Brake System (ABS)
ABS (or ESC) will not prevent acci-
dents due to improper or dangerous
driving maneuvers. Even though
ABS (or ESC) helps improve vehicle
control during emergency braking,
always maintain a safe distance
between you and objects ahead.
Vehicle speeds should always be
reduced during extreme road condi-
tions.
The vehicle should be driven at
reduced speeds in the following cir-
cumstances:
 When driving on rough, gravel or
snow-covered roads
 When driving with tire chains installed
 When driving on roads where the road surface is pitted or has differ-
ent surface heights.
Driving in these conditions increases
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 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.
 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.

Driving your vehicle
The ABS warning light will stay on for
approximately 3 seconds after the
ignition switch or ENGINE
START/STOP button 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 but your regular
brakes will work normally. Contact an
authorized Kia dealer as soon as
possible. When you drive on a road with
poor 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 the 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.

When operatingWhen the ESC is in opera-
tion, ESC indicator light
blinks.
 When the ElectronicStability Control is operat-
ing properly, you can feel a
slight pulsation in the vehi-
cle. This is only the effect
of brake control and indi-
cates nothing unusual.
 When moving out of the mud or slippery road,
pressing the accelerator
pedal may not cause the
engine rpm (revolutions
per minute) to increase.ESC operation off

ESC OFF usage
When driving
 It’s a good idea to keep the ESCturned on for daily driving whenev-
er possible.
 To turn ESC off while driving, press the ESC OFF button while driving
on a flat road surface.
Hill-start Assist Control (HAC)
The Hill-start Assist Control (HAC) is
designed to prevent 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- Operating
ESC
Never press the ESC OFF but-
ton while ESC is operating.
If the ESC is turned off while
ESC is operating, the vehicle
may go out of control.
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 pres-
sure sufficient to prevent your
vehicle from rolling backward
and causing an accident. Don’t
release the brake pedal until you
are ready to accelerate forward.
CAUTION
 The HAC does not operate when the transmission shiftlever is in the P (Park) or N(Neutral) position.
 The HAC activates even though the ESC is off but itdoes not activate when theESC has malfunctioned.
