WARNING - Fuel Filling
Fuel may be under pressure.
Always remove the fuel cap
carefully and slowly. If the cap is
venting fuel or if a hissing sound
is heard, wait until the condition
stops before completely
removing the cap. If these
precautions are not followed,
fuel may spray out and cause
serious personal injury.
WARNING
Automotive fuels are flammable/
explosive materials. When
refueling, please note the
following guidelines carefully.
Failure to follow these
guidelines may result in severe
personal injury, severe burns or
death by fire or explosion.
 Before refueling always note
the location of the Emergency
Gasoline Shut-Off, if available,
at the gas station facility.
 Before touching the fuel
nozzle or fuel filler cap, you
should eliminate potentially
dangerous static electricity
discharge by touching
another metal part of the front
of the vehicle, a safe distance
away from the fuel filler neck,
nozzle, or other gas source.
 Do not get back into a vehicle
once you have begun
refueling. Do not touch, rub
or slide against any item or
fabric (polyester, satin, nylon,
etc.) capable of producing
static electricity. Static
electricity discharge can
ignite fuel vapors resulting in
explosion. If you must re-
enter the vehicle, you should
once again eliminate
potentially dangerous static
electricity discharge by
touching a metal part of the
vehicle, away from the fuel
filler neck, nozzle or other
gasoline source.
 When using a portable fuel
container be sure to place the
container on the ground prior
to refueling. Static electricity
discharge from the container
can ignite fuel vapors
causing a fire. Once refueling
has begun, contact with the
vehicle should be maintained
until the filling is complete.
Use only portable fuel
containers designed to carry
and store gasoline.
 Do not use cellular phones
around a gas station or while
refueling any vehicle. Electric
current and/or electronic
interference from cellular
phones can potentially ignite
fuel vapors causing a fire. If
you must use your cellular
phone, use it in a place away
from the gas station.
 When refueling always shut
the engine off. Sparks
produced by electrical
components related to the
engine can ignite fuel vapors
causing a fire.

• 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.

IGNITION SWITCH ILLUMINATED IGNITION
SWITCHWhenever a door is opened, the ignition
switch will be illuminated for your
convenience, provided the ignition
switch is not in the “ON” position. The
light will go off approximately 10
seconds after closing the door or when
the ignition switch is turned on.
IGNITION SWITCH AND
ANTITHEFT STEERING
COLUMN LOCK IGNITION SWITCH POSITIONLOCKThe steering wheel is locked to protect
against theft. The ignition key can be
removed only in the LOCK position. For
vehicles equipped with an automatic
transaxle, it also locks the gear shift lever
in the P (Park) position.
ACC (ACCESSORY)Turning the ignition switch to this
position unlocks the steering wheel and
will allow some of your vehicle’s
electrical accessories such as the radio to
operate when the engine is OFF.ONTurning the ignition switch to this
position allows you to test your vehicle’s
warning lights (except the brake system
warning light) to make sure they work
before you start the engine. The ignition
key returns to the ON position once the
engine is started and remains in this
position while the engine is running.
Do not leave the ignition switch in the
ON position for extended periods with
the engine OFF because the battery will
discharge.

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.

✻
NOTICE
For safety, the engine will not start
if the clutch pedal is not depressed
fully on manual transaxle equipped
models.
WARNING
• Never turn the ignition switch
to LOCK or ACC while the
vehicle is moving. This could
result in loss of directional
control and braking function,
which could cause an
immediate accident.
 Never reach for the ignition
switch, or any other controls,
through the steering wheel
while the vehicle is in motion.
Failure to observe this
warning can result in loss of
vehicle steering and braking
control, which may result in
an accident.

STARTING THE ENGINE1. Make sure the parking brake is applied.
2.Manual Transaxle- Depress the
clutch pedal fully and shift the
transaxle into NEUTRAL. Keep the
clutch pedal depressed while
cranking the engine.
(For safety, the engine will not start if
the clutch pedal is not depressed fully
on manual transaxle equipped
models.)
Automatic Transaxle- Place the
transaxle shift lever in P (Park).

warm up without depressing the
accelerator.
Whether the engine is cold or warm, it
should be started without depressing the
accelerator.If the engine fails to start using this
procedure, attempt the following.
The engine fails to start when the engine
is cold (engine coolant temperature is
below 32ºF/0ºC):
A no start condition may be caused by an
engine that has become flooded (has
excessive fuel in the cylinders). If this is
the case, follow the starting procedure
below.
1. Make sure the parking brake is applied.
2.Manual Transaxle- Depress the
clutch pedal fully and shift the
transaxle into N (Neutral). Keep the
clutch pedal depressed while
cranking the engine.

for about 10 seconds before driving.In some models, the starter may not
operate if:
• In an automatic transaxle, the shift lever
is NOT in P (Park) or N (Neutral).
• In a manual transaxle, the clutch
pedal is not fully depressed.
Excessive engine noise (from valve
tappets) may occur if the engine has not
been operated for an extended period.
