als to the front most position by push-
ing the “▼” portion of the switch.
3. Adjust the seat position and the steer-
ing wheel angle properly.
4. Move the pedals toward you until you
can fully depress the brake pedal by
pushing the “▲” portion of the switch.
5. Depress the pedals a few times to get

Parking brake To engage the parking brake, first apply
the foot brake and then without pressing
the release button in, pull the parking
brake lever up as far as possible. In addi-
tion it is recommended that when parking
the vehicle on a gtadient, the shift lever
should be positioned in the appropriate
low gear on manual transaxle vehicles or
in the P(Park) position on automatic
transaxle vehicles.✽ ✽
NOTICEDriving with the parking brake applied
will cause excessive brake pad and
brake rotor wear.
WARNING
- Pedal adjust-
ment
Adjust the pedals after parking
the vehicle on level ground. Never
attempt to adjust the pedals while
the vehicle is moving.
Never adjust the pedals with your
foot on the accelerator pedal as
this may result in increasing the
engine speed and acceleration.
Make sure that you can fully
depress the brake pedal before
driving. Otherwise, you may not
be able to hold down the brake
pedal firmly in an emergency
stop.

Driving your vehicle
To release the parking brake, first apply
the foot brake and pull the parking lever
slightly.
Secondly, depress the release button
and lower the parking brake lever while
holding the button.Check the brake warning light by turning
the ignition switch ON (do not start the
engine). This light will be illuminated
when the parking brake is applied with
the ignition switch 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, there
may be a malfunction in the brake sys-
tem. Immediate attention is necessary.
If at all possible, cease driving the vehi-
cle immediately. If that is not possible,
use extreme caution while operating the
vehicle and only continue to drive the
vehicle until you can reach a safe loca-
tion or repair shop.
WARNING
- Parking brake
To prevent unintentional move-
ment when stopped and leaving
the vehicle, do not use the
gearshift lever in place of the
parking brake. Set the parking
brake AND make sure the
gearshift lever is securely posi-
tioned in 1st (First) gear or R
(Reverse) for manual transaxle
equipped vehicles and in P (Park)
for automatic transaxle equipped
vehicles.
Never allow a person who is unfa-
miliar with the vehicle or children
to touch the parking brake. If the
parking brake is released unin-
tentionally, serious injury may
occur.

Driving your vehicle14 4Parking on curbed streets When parking your vehicle on an uphill
grade, park as close to the curb as
possible and turn the front wheels
away from the curb so that the front
wheels will contact the curb if the vehi-
cle moves backward.
When parking your vehicle on a down-
hill grade, park as close to the curb as
possible and turn the front wheels
toward the curb so that the front
wheels will contact the curb if the vehi-
cle moves forward.
Anti-lock brake system (ABS)
(if equipped)
The ABS continuously senses the speed
of the wheels. If the wheels are going to
lock, the ABS repeatedly modulates the
hydraulic brake pressure to the wheels.
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 ABS is active.
In order to obtain the maximum benefit
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
warrants and allow the ABS to control the
force being delivered to the brakes.
Even with the anti-lock brake system,
your vehicle still requires sufficient
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 pre-
vent accidents resulting from exces-
sive speeds.
On loose or uneven road surfaces,
operation of the anti-lock brake system
may result in a longer stopping dis-
tance than for vehicles equipped with a
conventional brake system.
WARNING
- ABS Brakes
Your ABS is not a substitute for
good driving judgement. You can
still have an accident. In fact, your
ABS will probably not be able to
prevent an accident in the following
driving conditions:
Dangerous driving, such as
neglecting safety precautions,
speeding, or driving too close to
the vehicle in front of you.
Driving at high speed in situa-
tions providing considerably less
traction, such as wet conditions
where hydroplaning could occur.
Driving too fast on poor road sur-
faces. The ABS is designed to
improve maximum braking effec-
tiveness on typical highways and
roads in good condition. On poor
road surfaces, the ABS may actu-
ally reduce braking effectiveness.

Driving your vehicle
✽ ✽
NOTICE• If the ABS warning light is on and
stays on, you may have a problem
with the ABS. In this case, however,
your regular brakes will work nor-
mally.
• The ABS warning light will stay on for
approximately 3 seconds after the
ignition switch 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. Contact an authorized Kia deal-
er as soon as possible.
✽ ✽
NOTICE• When you drive on a road having
poor traction, such as an icy road, and
operate your brakes continuously, the
ABS will be active continuously and
the ABS warning light may illuminate.
Pull your car over to a safe place and
stop the engine.
• Restart the engine. If the ABS warn-
ing light is off, then your ABS is nor-
mal. Otherwise, you may have a prob-
lem with the ABS. Contact an author-
ized Kia dealer as soon as possible.✽ ✽
NOTICEWhen 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 is malfunctioning.
• Do not pump your brakes!
• Have the battery recharged before
driving the vehicle.

tion, press the RES/ACCEL switch locat-
ed on your steering wheel. You will return

The Electronic Stability Control (ESC)
monitors information from various vehicle
sensors and then compares the driver's
commands with the actual behavior of the
vehicle. If an unstable condition occurs - a
sudden evasive movement for example -
ESC intervenes within fractions of a
second via the engine computer and
brake system and attempts to stabilize
the vehicle.

cator lights illuminate for

ESC OFF usageWhen driving It’s a good idea to keep the ESC turned
on for daily driving whenever possible.
To turn ESC off while driving, press the
ESC OFF button while driving on a flat
road surface.
Never press ESC OFF button while ESC
is operating (ESC indicator light blinks).
If ESC is turned off while ESC is operat-
ing, the vehicle may slip out of control.✽ ✽
NOTICE• When measuring the vehicle speed
with a Chassis dynamo-meter, make
sure the ESC is turned off (ESC OFF
light illuminated). If the ESC is left
on, it may prevent the vehicle speed
from increasing, and cause a false
diagnosis of a faulty speedometer.
• Turning the ESC off does not affect
ABS or brake system operation.
• When attempting to free an ESC-
equipped vehicle that is stuck in snow,
sand, or mud, use the ESC OFF but-
ton to temporarily deactivate the ESC
system.
WARNING
- ESC
Never press the ESC OFF button
while ESC may be operating, such
as on slippery or winding roads. If
the ESC is turned off while ESC is
operating, the vehicle may slip out
of control. To turn ESC off while
driving, press the ESC OFF button
while driving on a flat, straight, dry
road surface.

If the light stays on, you may have a
problem with your ABS. Contact an
authorized Kia dealer as soon as possi-
ble.
Electronic brake force
