Electronic stability control (ESC)
The Electronic Stability control (ESC)
system is designed to stabilize the vehicle
during cornering maneuvers. ESC checks
where you are steering and where the
vehicle is actually going. ESC applies the
brakes at individual wheels and
intervenes in the engine management
system to stabilize the vehicle.The Electronic Stability Control (ESC)
system is an electronic system designed
to help the driver maintain vehicle control
under adverse conditions. It is not a
substitute for safe driving 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 con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
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 vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the Electronic Stability
Control System is functioning properly.
WARNING
Never drive too fast for the road
conditions or too quickly when cor-
nering. Electronic stability control
(ESC) will not prevent accidents.
Excessive speed in turns, abrupt
maneuvers and hydroplaning on
wet surfaces can still result in seri-
ous accidents. Only a safe and
attentive driver can prevent acci-
dents by avoiding maneuvers that
cause the vehicle to lose traction.
Even with ESC installed, always fol-
low all the normal precautions for
driving - including driving at safe
speeds for the conditions.

Good braking practices
After parking the vehicle, check to be
sure the parking brake is not engaged
and that 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 car is washed. Wet brakes
can be dangerous! Your car will not
stop as quickly if the brakes are wet.
Wet brakes may cause the car 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 car
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 authorized KIA dealer for assis-
tance. Don't coast down hills with the car out
of gear. This is extremely hazardous.
Keep the car 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 driv-
ing can be dangerous because it can
result in the brakes overheating and
losing their effectiveness. It also
increases the wear of the brake com-
ponents.
If a tire goes flat while you are driving, apply the brakes gently and keep the
car 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.
WARNING
Whenever leaving vehicle orparking, always set the parking
brake as far as possible and fully
engage the vehicle's transaxle
into the park position. Vehicles
not fully engaged in park with the
parking brake set are at risk for
moving inadvertently and injur-
ing yourself or others.
All vehicles should always have the parking brake fully engaged
when parking to avoid inadver-
tent movement of the car which
can injure occupants or pedestri-
ans.

529
Driving your vehicle
If your car is equipped with an auto-matic transaxle, don't let your car
creep forward. To avoid creeping for-
ward, keep your foot firmly on the
brake pedal when the car is stopped.
Use caution when parking on a hill. Firmly engage the parking brake and
place the gear selector lever in P
(Park). If your car is facing downhill,
turn the front wheels into the curb to
help keep the car from rolling. If your
car is facing uphill, turn the front
wheels away from the curb to help
keep the car from rolling. If there is no
curb or if it is required by other condi-
tions to keep the car from rolling, block
the wheels. Under some conditions your parking
brake can freeze in the engaged posi-
tion. This is most likely 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 gear
selector lever in P (Park) (automatic
transaxle) and block the rear wheels so
the car cannot roll. Then release the
parking brake.
Do not hold the vehicle on the upgrade with the accelerator pedal. This can
cause the transaxle to overheat.
Always use the brake pedal or parking
brake.

ting a speed.
Use the cruise control system only when traveling on open
highways in good weather.
Do not use the cruise control when it may not be safe to keep
the car at a constant speed, for
instance, driving in heavy or
varying traffic, or on slippery
(rainy, icy or snow-covered) or
winding roads or over 6% up-hill
or down-hill roads.
