Moving up a steep grade from a
standing startTo move up a steep grade from a stand-
ing start, depress the brake pedal, shift
the shift lever to D (Drive). Select the
appropriate gear depending on load
weight and steepness of the grade, and
release the parking brake. Depress the
accelerator gradually while releasing the
service brakes.
When accelerating from a stop on a
steep hill, the vehicle may have a ten-
dency to roll backwards. Shifting the
shift lever into 2 (Second Gear) while
in Sport mode will help prevent the
vehicle from rolling backwards.Ignition key interlock systemThe ignition key cannot be removed
unless the shift lever is in the P (Park)
position. If the ignition switch is in any
other position, the key cannot be
removed.
Shift lock systemFor your safety, the Automatic Transaxle
has a shift lock system which prevents
shifting the transaxle out of P (Park)
unless the brake pedal is depressed.
To shift the transaxle out of P (Park):
1. Depress and hold the brake pedal.
2. Start the engine or turn the ignition tothe ON position.
3. Move the shift lever.
If the brake pedal is repeatedly
depressed and released with the shift
lever in the P (Park) position, a chattering
sound near the shift lever may be heard.
This is a normal condition.
Shift-lock overrideIf the shift lever should fail to move from
the P (Park) position with the brake pedal
depressed, continue depressing the
brake, then do the following:
1. Carefully remove the cap covering the S/Lock override access hole which is
located on the right side of the shift
lever.
2. Insert the screwdriver into the access hole and press down on the key.
3. Depress the lock release button and move the shift lever.
4. Have your vehicle inspected by an authorized Kia dealership immediately.

pitched warning sound from your front
brakes or rear brakes (if equipped). You
may hear this sound come and go or it
may occur whenever you depress the
brake pedal.
Please remember that some driving
conditions or climates may cause a
brake squeal when you first apply (or
lightly apply) the brakes. This is nor-
mal and does not indicate a problem
with your brakes.
✽ ✽NOTICETo avoid costly brake repairs, do not
continue to drive with worn brake pads.

and brake pedals, turn the ignition key to
the “ON” position with the selector lever
in the "P" position and push the switch.
If you push the “” portion of the switch,
the pedals move rearward.
If you push the “” portion of the switch,
the pedals move forward.

means your vehicle needs service.
If you ignore this audible warning,
you will eventually lose braking per-
formance, which could lead to a
serious accident.
CAUTION
Always replace brake pads as com-
plete front or rear axle sets toensure smooth brake performance.

tem. Immediate attention is necessary.

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

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

✽
✽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.

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.
ESC operationESC ON condition
 When the ignition is turnedON, ESC and ESC OFF indi-
cator lights illuminate for
approximately 3 seconds,
then ESC is turned on.
 Press the ESC OFF button for at least half a second after
turning the ignition ON to turn
ESC off. (ESC OFF indicator
will illuminate). To turn the
ESC on, press the ESC OFF
button (ESC OFF indicator
light will go off).
 When starting the engine, you may hear a slight ticking
sound. This is the ESC per-
forming an automatic system
self-check and does not indi-
cate a problem.
When operating
When the ESC is in operation,
ESC indicator light blinks.
 When the Electronic StabilityControl is operating properly,
you can feel a slight pulsation
in the vehicle. This is only the
effect of brake control and
indicates nothing unusual.
 When moving out of the mud or slippery road, pressing the
accelerator pedal may not
cause the engine rpm (revo-
lutions per minute) to
increase.
