Knowing your vehicle
✽
✽NOTICE• If luggage or other objects are placed
on the front passenger's seat or if the
temperature of the seat changes while
the seat is unoccupied, the "PASSEN-
GER AIR BAG OFF" indicator may
blink. These conditions do not indi-
cate a problem.
• Do not put heavy objects on the front passenger's seat. This may cause front
passenger air bag deployment in the
event of an accident, thus increasing
your repair costs.
(Continued)
 Kia does not endorse nor will it
support any changes to any part
or structure of the vehicle that
could affect the advanced air bag
system, including the occupant
classification system.
Specifically, the front passenger
seat, dashboard or door should
not be replaced except by an
authorized Kia dealer using origi-
nal Kia parts designed for this
vehicle and model. Any other
such replacement or modification
could adversely affect the opera-
tion of the occupant classification
system and your advanced air
bags.
For the same reason, do not
attach anything to the seat, dash-
board or door, even temporarily. If
the system is adversely affected,
it could cause severe personal
injuries or death in a collision.
(Continued)
(Continued)
 Do not place sharp objects on thefront passenger seat. These can
damage the occupant classifica-
tion system, if they puncture the
seat cushion.
 Do not install accessory seat cov- ers on the front seats, since these
will interfere with proper sensor
operation.
WARNING
 The front seat passenger’s air bagis much larger than the steering
wheel air bag and inflates with
considerably more force. It can
seriously hurt or kill a passenger
who is not in the proper position
and wearing the safety belt prop-
erly. The front passengers
should always move their seat as
far back as practical and sit back
in their seat.
 It is essential that the front pas- sengers always wear their safety
belts when vehicle is in motion,
even when the vehicle is moving
in a parking lot or up a driveway
into garage.
 If the driver brakes the vehicle heavily in urgent situations, occu-
pants will be thrown forward. If
front passengers are not wearing
the safety belts, they will be
directly in front of the air bags
when inflation occurs. In that sit-
uation, severe injury or death is
possible.

Driving your vehicle
✽
✽NOTICE• To avoid damage to your transaxle, do
not accelerate the engine in R
(Reverse) or any forward gear posi-
tion with the brakes on.
• When stopped on an uphill grade, do not hold the vehicle stationary with
engine power. Use the service brake
or the parking brake.
• Do not shift from N (Neutral) or P (Park) into D (Drive), or R (Reverse)
when the engine is above idle speed.Transaxle rangesP (Park)This position locks the transaxle and pre-
vents the front wheels from rotating.
Always come to a complete stop before
shifting into this position.
✽ ✽ NOTICEThe transaxle may be damaged if you
shift into P (Park) while the vehicle is in
motion.
R (Reverse)Use this position to drive the vehicle
backward.✽ ✽NOTICEAlways come to a complete stop before
shifting into or out of R (Reverse); you
may damage the transaxle if you shift
into R while the vehicle is in motion.N (Neutral)With the gearshift in the N position, the
wheels and transaxle are not locked. The
vehicle will roll freely even on the slight-
est incline unless the parking brake or
service brakes are applied.D (Drive)This is the normal forward driving posi-
tion. The transaxle will automatically shift
through a 5-gear sequence, providing the
best fuel economy and power.
For extra power when passing another
vehicle or climbing grades, depress the
accelerator fully, at which time the
transaxle will automatically downshift to
the next lower gear.
(Continued)
 Do not use the P (Park) position in
place of the parking brake.
Always make sure the shift lever
is latched in the P (Park) position
AND set the parking brake fully.
 Before leaving the driver’s seat, always make sure the shift lever
is in the P (Park) position. Set the
parking brake fully, shut the
engine off and take the key with
you. Unexpected and sudden
vehicle movement can occur if
you do not follow these precau-
tions in the order specified.
 Never leave a child unattended in a vehicle.
WARNING
- Automatic
transaxle
 Shifting into P (Park) while thevehicle is in motion will cause the
drive wheels to lock which will
cause you to lose control of the
vehicle.

Driving your vehicle
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.

4Power brakes Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
In the event that the power-assisted
brakes lose power because of a stalled
engine or some other reason, you can
still stop your vehicle by applying greater
force to the brake pedal than you nor-
mally would. The stopping distance, how-
ever, will be longer.
When the engine is not running, the
reserve brake power is partially depleted
each time the brake pedal is applied. Do
not pump the brake pedal when the
power assist has been interrupted.
Pump the brake pedal only when neces-
sary to maintain steering control on slip-
pery surfaces.
In the event of brake failure If service brakes fail to operate while the
vehicle is in motion, you can make an
emergency stop with the parking brake.
The stopping distance, however, will be
much greater than normal.
BRAKE SYSTEM
WARNING
- Parking brake
Pulling the parking brake while the
vehicle is moving at normal speeds
can cause a sudden loss of control
of the vehicle. If you must use the
parking brake to stop the vehicle,
use great caution in applying the
brake.
WARNING -
Brakes
 Do not drive with your foot rest-
ing on the brake pedal. This will
create abnormal high brake tem-
peratures, excessive brake lining
and pad wear, and increased
stopping distances.
 When descending a long or steep hill, shift to a lower gear and
avoid continuous application of
the brakes. Continuous brake
application will cause the brakes
to overheat and could result in a
temporary loss of braking per-
formance.
 Wet brakes may result in the vehi- cle not slowing down at the usual
rate and pulling to one side when
the brakes are applied. After
going through water, apply the
brakes lightly to regain smooth
braking performance.

Disc brakes wear indicator Your vehicle has disc brakes.
When your brake pads are worn and it's
time for new pads, you will hear a high-
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.
Power adjustable pedals
(if equipped)To adjust the position of the accelerator
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.
WARNING
- Brake wear
This brake wear warning sound
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.

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 asneglecting 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.

✽
✽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.
