vehicle immediately. If that is not pos-
sible, use extreme caution while
operating the vehicle and only contin-
ue to drive the vehicle until you can

✽ ✽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)
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.
ODEP051016N
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 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.

Good braking practices
Check to be sure the parking brakeis not engaged and the parking
brake indicator light is out before
driving away.
Driving through water may get the brakes wet. They can also get wet
when the vehicle is washed. Wet
brakes can be dangerous! Your
vehicle will not stop as quickly if the
brakes are wet. Wet brakes may
cause the vehicle to pull to one side.
To dry the brakes, apply the brakes
lightly until the braking action
returns to normal, taking care to
keep the vehicle under control at all
times. If the braking action does not
return to normal, stop as soon as it
is safe to do so and call an author-
ized Kia dealer for assistance.
Don't coast down hills with the vehicle out of gear. This is extreme-
ly hazardous. Keep the vehicle in
gear at all times, use the brakes to
slow down, then shift to a lower
gear so that engine braking will
help you maintain a safe speed. 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 a dual clutch 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 (Dual
clutch 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, block
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 (Dual clutch
transmission) and block 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 transaxle to
overheat. Always use the brake
pedal or parking brake.
