Knowing your vehicle
CAUTION -
Air bag/Pre-
tensioner dust
When the air bags and pre-tension-
ers are activated, a loud noise maybe heard and fine dust, which mayappear to be smoke, may be visible in the passenger compartment. Thisdust is not toxic. The dust maycause skin irritation and should not be breathed for prolonged periods.Ventilate the vehicle after impactand wash your hands and face thor- oughly after an accident.
WARNING
- Air bag/pre-
tensioner warning light
If the SRS air bag warning light
does not illuminate when the igni-
tion key is turned to “ON”, or if it
remains illuminated after approxi-
mately 6 seconds, or if it illuminates
while the vehicle is being driven,
please have an authorized Kia deal-
er inspect the pre-tensioner and air
bag system as soon as possible.
WARNING
- Safety belt adjustment
To obtain maximum benefit from a
pre-tensioner seat belt:
 The safety belt must be worn cor-
rectly.
 The safety belt must be adjusted to the correct position.
WARNING
- Replacing
used pre-tensioners
 Pre-tensioners are designed to
operate once. After activation,
pre-tensioner seat belts must be
replaced. All seat belts, of any
type, should always be replaced
after they have been worn during
a collision.
 Do not attempt to replace the pre- tensioners yourself. This must be
done by an authorized Kia dealer.
CAUTION -
Hot parts
The pre-tensioner assembies mech-anism becomes hot during activa- tion. Do not touch the pre-tensionerseat belt assembly for several min-utes after they have been activated.
WARNING
- Damaging the
pre-tensioners
 Do not hit or strike the pre-ten-
sioner assemblies, especially
with a tool or heavy object.
 Do not attempt to service or repair the pre-tensioners.

331
Knowing your vehicle
Safety belts provide the best restraint
when:
The seatback is upright.
 The occupant is sitting upright (not
slouched).
 The lap belt is snug across the hips.
 The shoulder belt is snug across the
chest.
 The knees are straight forward.
WARNING
- After a collision
 Lap/shoulder belt assemblies
may be stretched or damaged
when subjected to the stress and
forces of a collision.
 The entire restraint system should be inspected following
any collision. All belts, retractors,
anchors and hardware damaged
by a collision should be replaced
before the vehicle is operated
again.
WARNING -
Cargo area
(if equipped)
Passengers should never be
allowed to ride in the cargo area of
a vehicle. No safety belts are pro-
vided for the cargo area. Persons
riding in the vehicle without a fas-
tened safety belt are much more
likely to suffer serious bodily injury
or death during an accident.
WARNING
- Twisted belts
A twisted or jammed safety belt
cannot restrain you properly. If you
cannot untwist or unjam the safety
belt, have an authorized Kia dealer
service it immediately. Never drive
or ride with a twisted or jammed
safety belt.
WARNING
- Belt use
Safety belts must be used correctly
to work properly in an accident.
Each seating position in your vehi-
cle has a specific safety belt assem-
bly that includes a buckle and
tongue designed to be used togeth-
er. (Continued)
(Continued)
Failure to heed these warnings and
follow these instructions will
increase the risk and severity of
injuries and the likelihood of death
in an accident.
 Use the shoulder portion of thesafety belt on the outside shoul-
der only.
 Never wear the shoulder portion of the safety belt under the out-
side arm or behind the back.
 Never swing the safety belt around your neck to fit over the
inside shoulder.
 Never wear the shoulder portion of the safety belt across the neck
or face.
 Wear the lap portion as low as possible. Be sure that the lap belt
fits snugly around the hips.
Never wear a lap portion of a
lap/shoulder belt over your waist;
it should always go over the
stronger area of your hips.
 Never use a single safety belt for more than one person.
 The front seatbacks should always remain in a comfortable,
upright position when the vehicle
is moving.

Knowing your vehicle
Air bag warning lightThe purpose of air bag warning light in
your instrument panel is to alert you of a
potential problem with your air bag -
Supplemental Restraint System (SRS).
When the ignition switch is turned ON,
the indicator light should blink or illumi-
nate for approximately 6 seconds, then
go off.
Have the system checked if:
The light does not turn on briefly when
you turn the ignition ON.
 The light stays on after the engine
starts.
 The light comes on while the vehicle is
in motion.
Air bag (Supplemental Restraint
System) service Your Supplemental Restraint System is
virtually maintenance-free. There are no
parts which you can service.
You must have the system serviced
under the following circumstances:
If an air bag ever inflates, the air bag
must be replaced. Do not try to remove
or discard the air bag by yourself. This
must be done by an authorized Kia
dealer.
 If the air bag warning indicator light
alerts you to a problem, have the air
bag system checked as soon as possi-
ble. Otherwise, your air bag system
may be ineffective.
WARNING
- Children
 Never put a child in the front pas-
senger seat, even if they are in a
child restraint. If the front passen-
ger air bag inflates, it may cause
severe or fatal injuries.
 When children are seated in the rear outboard seats in which cur-
tain air bags are equipped, be
sure to put the child restraint sys-
tem as far away from the door
side as possible, and secure the
child restraint system to be
locked in position.
AIR
BAG
CAUTION
- No modification
Do not modify any part of the air
bag system. Modification couldmake the air bag system ineffective or could cause unnecessarydeployment.

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.

Driving your vehicle
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.
