3) Sub key
Similar to the master key, this key
will only function in the ignition and
the door locks, but it will not operate
the trunk and the glove box.
One side of the key has the Kia logo
and the other side has the “S”
symbol.
IMMOBILIZER SYSTEMYour vehicle is equipped with an
electronic engine immobilizer system to
reduce the risk of unauthorized vehicle
use.
Your immobilizer system is comprised
of a small transponder in the ignition
key, and antenna coil in the key cylinder
and IU (Immobilizer Unit) in the
instrument panel.
With this system, whenever you insert
your ignition key into the ignition switch
and turn it to ON, the antenna coil in the
ignition switch receives a signal from the
transponder in the ignition key and then
sends the signal to the IU (Immobilizer
Unit).
The IU (Immobilizer Unit) checks the
signal and determines whether the
ignition key is valid.
If the key is determined to be valid, the
engine will start.
If the key is determined to be invalid, the
engine will not start.To deactivate the immobilizer system:
Insert the ignition key into the key
cylinder and turn it to the ON position.
To activate the immobilizer system:
Turn the ignition key to the OFF
position. The immobilizer system
activates automatically. Without a valid
ignition key for your vehicle, the engine
will not start.

CAUTION
Don’t lose your ID key or forget the
password.
Always keep your ID key in a place
where you remember and record
your password. If you don’t have
both the password and ID key,
consult your authorized Kia dealer.
✻
NOTICE
When starting the engine, do not
use the key with other immobilizer
keys around. Otherwise the engine
may not start or may stop soon
after it starts. Keep each key
separately not to have any
malfunction after you receive your
new vehicle.

AIR BAG WARNING LIGHTThe purpose of the air bag warning light
in your instrument panel is to alert you of
a potential problem with your Air Bag -
Supplemental Restraint System (SRS).
Have the system checked if:
• The light does not illuminate when
you turn the ignition ON.
• The light stays ON after the engine
starts.
• The light comes ON or flashes while
you are driving.
SUPPLEMENTAL RESTRAINT
SYSTEM SERVICEYour 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 of a problem, have the air
bag system checked as soon as
possible. Otherwise, your air bag
might not inflate when you need it.
The entire SRS system must be inspected
by an authorized Kia dealer 10 years
after the vehicle manufacture date.
AIR BAG WARNING LIGHT
AIR
BAG
AS2B03035
 Do not use excessive force
on the side of the seat.
 Do not place any objects
over the airbag or between
the airbag and yourself.
 Do not place any objects (an
umbrella, bag,etc.) between
the front door and the front
seat. Such objects may
become dangerous projectiles
and cause injury if the side air
bag inflates.
 To prevent unexpected
deploy-ment of the side air
bag that may result in
personal injury, avoid impact
to the side airbag sensor
when the ignition key is
“ON”.

• To remove the cap, turn it coun
terclockwise.
• To install the cap, turn it clock wise
until it “clicks”.
This indicates that the cap is securely
tightened.The fuel filler neck is designed to
prevent filling the fuel tank with
anything but unleaded fuel.
Always insure that the
engine is OFF before and
during refueling. Once
refueling is complete, check
to make sure the fuel filler
cap and door are securely
closed, before starting the
engine.
 Do not light any fire around a
gas station. DO NOT use
matches or a lighter and DO
NOT SMOKE or leave a lit
cigarette in your vehicle while
at a gas station especially
during refueling. Automotive
fuel is highly flammable and
can, when ignited, result in
explosion by flames.
 If a fire breaks out during
refueling, leave the vicinity of
the vehicle, and immediately
contact the manager of the
gas station or contact the
police and local fire
department. Follow any
safety instructions they
provide.
✻
NOTICE
A loose fuel filler cap may cause the
OBD-II Malfunction Indicator
Light ( ) light in the instrument
panel to illuminate unnecessarily.
Always ensure that the fuel filler
cap is tight.
CHECK
✻
NOTICE
If the fuel filler cap requires
replacement, use only a genuine
Kia cap. An incorrect fuel filler cap
can result in a serious malfunction
of the fuel system or emission
control system. Correct
replacement caps are available at
Authorized Kia Dealers.

STARTTurn the ignition key to the START
position to start the engine. The engine
will crank until you release the key, then
it returns to the ON position. Also, the
brake warning indicator illuminates to
check the bulb in this position.
Difficulty in turning the ignition key to
the START position can be caused by
pressure on the switch from the steering
column. To allow the ignition key to turn,
move the steering wheel right or left to
release the tension and then turn the key.
AUTOMATIC TRANSAXLEWhen turning the ignition switch to the
LOCK position, the shift lever must be
in the P (Park) position.MANUAL TRANSAXLEWhen turning the ignition switch to the
LOCK position, push the key inward at
the ACC position and turn the key
toward the LOCK position.

MOVING UP A STEEP GRADE
FROM A STANDING STARTTo move up a steep grade from a
standing 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
tendency to roll backwards. Shifting
the shift lever into 2 (Second Gear)
while in Sports mode will help prevent
the vehicle from rolling backwards.
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
key to the ON position.
3. Depress the lock release button and
move the shift lever.
When the ignition switch is in the ACC
or LOCK position, the transaxle cannot
be shifted from P (Park).
If the brake pedal is repeatedly depressed
and released with the shift lever in the P
(Park) position, a chattering noise near
the shift lever may be heard.
This is a normal condition.
Note that the 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.
4-11
CAUTION
 Shift into the “R” and “P” posi-
tion only when the vehicle has
completely stopped.
 Do not accelerate the engine in
reverse or any of the forward
positions with the brakes applied.
 Always apply the footbrake when
shifting from “P” or “N”, to “R”
or “D” position.
 Do not use the “P” (Park) posi-
tion in place of the parking
brake. Always set the parking
brake, shift the transaxle into
“P” (Park) position and turn off
the ignition when you leave the
vehicle, even momentarily.
Never leave the vehicle unat-
tended while the engine is run-
ning.
 Check the automatic transaxle
fluid level regularly, and add
fluid as necessary.

Check the brake warning light each time
you start the engine. The light is located
in the instrument panel. This warning
light will be illuminated when the engine
is running and the parking brake is set.
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
system. Immediate attention is
necessary.
If at all possible, cease driving the
vehicle immediately. If that is not
possible, use extreme caution in
operating the vehicle and only drive it
until you reach the first safe location or a
repair shop.

CAUTION
When stopped, do not use the
gearshift lever in place of the park-
ing brake. Always set the parking
brake fully AND make sure the
gearshift lever is securely positioned
in P (Park) with an automatic
transaxle or in 1st (First) or R
(Reverse) gear with a manual
transaxle.

POWER STEERING Power steering uses energy from the
engine to assist you in steering the
vehicle. If the engine is off or if the
power steering system becomes
inoperative, the vehicle may still be
steered, but it will require increased
steering effort.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power
steering system checked by an
Authorized Kia Dealer.
TILT STEERINGA tilt steering wheel allows you to adjust
the steering wheel before you drive. You
can also raise it to the highest level to
give your legs more room when you exit
and enter the vehicle.
To tilt the wheel, hold the steering wheel
and pull the lock release lever.
Move the steering wheel to a comfortable
level.

If the power steering drive belt
breaks or if the power steering
pump malfunctions, the steering
effort will become greatly
increased.
