Immobilizer system (if equipped)
Your vehicle is equipped with an elec-
tronic 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 electronic devices inside the vehicle.
With the immobilizer system, whenever
you insert your ignition key into the igni-
tion switch and turn it to ON, it checks
and determines and verifies that the igni-
tion 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 sys-tem:
Insert the ignition key into the key cylin-
der and turn it to the ON position.
To activate the immobilizer system:
Turn the ignition key to the OFF position.
The immobilizer system activates auto-
matically. Without a valid ignition key for
your vehicle, the engine will not start.
✽ ✽ 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 separate in order to avoid a starting
malfunction.
WARNING
In order to prevent theft of your
vehicle, do not leave spare keys
anywhere in your vehicle. Your
Immobilizer password is a cus-
tomer unique password and should
be kept confidential. Do not leave
this number anywhere in your vehi-
cle.

"Limp Home" Mode and RelatedProcedures
If the immobilizer warning indicator blinks
for five seconds when the ignition key is
turned to the "ON" position, this indicates
the immobilizer system requires service.
The engine cannot be started without
using the procedure below.
The following procedure describes how
to start the engine using the limp home
function (0, 1, 2, 3 as a sample pass-
word).
✽ ✽ NOTICE
You can get a limp home password when
the vehicle is first delivered to you. If
you do not have a password, consult
your authorized KIA dealer.
1. To activate the password, turn the igni-
tion key "ON" and "OFF" according to
the digit numbers. The immobilizer indi-
cator will blink along with the operation
of the ignition key. For example, turn
the ignition key once for digit number
"1", and twice for "2", and so on. For
the digit number "0", you must cycle
the ignition key 10 times.
2. Wait for 3~10 seconds. 3. You may set the remaining number of
digits by following steps 1 and 2.
4. If all of the four password digits have been successfully entered, turn the
ignition key "ON" and check that the
immobilizer indicator illuminates. From
this time, you have to start your engine
within 30 seconds. If you try to start
your engine after 30 seconds, your
engine will not start.
✽ ✽ NOTICE
If the engine stalls while driving in the
"limp home" mode, you can start your
engine within 3 seconds without re-
entering the password.
If the immobilizer indicator blinks for five
seconds, you must re-enter the password
(steps 1~4).
After performing the limp home activation
procedure, consult with your authorized
KIA dealer as soon as possible.
CAUTION
If the password is entered incor-
rectly three consecutive times,wait for about one hour to per- form the limp home activationprocedure again.
If you cannot start your engine using the limp home activationprocedure, have your vehicletowed by an authorized KIA deal- er.

FUEL FILLER LID
WARNING - Refueling
If pressurized fuel sprays out, itcan cover your clothes or skin
and thus subject you to the risk
of fire and burns. Always remove
the fuel cap carefully and slowly.
If the cap is venting fuel or if you
hear a hissing sound, wait until
the condition stops before com-
pletely removing the cap.
Do not "top off" after the nozzle automatically shuts off when
refueling.
Tighten the cap until it clicks, oth- erwise the Malfunction Indicator
Light will illuminate.
Always check that the fuel cap is installed securely to prevent fuel
spillage in the event of an acci-
dent.OMG035066OMG035067

(Continued)Use only approved portable plas-
tic fuel containers designed to
carry and store gasoline.
Do not use cellular phones while refueling. Electric current and/or
electronic interference from cel-
lular phones can potentially
ignite fuel vapors causing a fire.
When refueling, always shut the engine off. Sparks produced by
electrical components related to
the engine can ignite fuel vapors
causing a fire. Once refueling is
complete, check to make sure the
filler cap and filler door are
securely closed, before starting
the engine.
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 fire.
(Continued)(Continued)
Do not get back into a vehicleonce you have begun refueling
since you can generate static
electricity by touching, rubbing
or sliding against any item or fab-
ric (polyester, satin, nylon, etc.)
capable of producing static elec-
tricity. Static electricity discharge
can ignite fuel vapors resulting in
rapid burning. If you must re-
enter the vehicle, you should
once again eliminate potentially
dangerous static electricity dis-
charge by touching a metal part
of the vehicle, away from the fuel
filler neck, nozzle or other gaso-
line source.
When using an approved 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.
(Continued)WARNING - Refueling dan-
gers
Automotive fuels are flammable
materials. When refueling, please
note the following guidelines care-
fully. Failure to follow these guide-
lines may result in severe personal
injury, severe burns or death by fire
or explosion.
Read and follow all warningsposted at the gas station facility.
Before refueling, note the loca- tion of the Emergency Gasoline
Shut-Off, if available, at the gas
station facility.
Before touching the fuel nozzle, you should eliminate potentially
dangerous static electricity dis-
charge by touching another metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas source.

Power steering
Power steering uses energy from the
engine to assist you in steering the vehi-
cle. 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 steer-
ing checked by an authorized KIA dealer.
✽ ✽
NOTICE
If the power steering drive belt breaks
or if the power steering pump malfunc-
tions, the steering effort will greatly
increase.
✽ ✽NOTICE
If the vehicle is parked for extended
periods outside in cold weather (below -
10°C/14°F), the power steering may
require increased effort when the engine
is first started. This is caused by
increased fluid viscosity due to the cold
weather and does not indicate a mal-
function.
When this happens, increase the engine
RPM by depressing accelerator until the
RPM reaches 1,500 rpm then release or
let the engine idle for two or three min-
utes to warm up the fluid.
D130300AFD
Tilt steering
Tilt steering allows you to adjust the
steering wheel before you drive. You can
also raise it to give your legs more room
when you exit and enter the vehicle.
The steering wheel should be positioned
so that it is comfortable for you to drive,
while permitting you to see the instru-
ment panel warning lights and gauges.
STEERING WHEEL
CAUTION
Never hold the steering wheel
against a stop (extreme right or leftturn) for more than 5 seconds withthe engine running. Holding the steering wheel for more than 5 sec-onds in either position may causedamage to the power steeringpump.
WARNING
Never adjust the angle of the steering wheel while driving. You
may lose steering control and
cause severe personal injury,
death or accidents.
After adjusting, push the steering wheel both up and down to be
certain it is locked in position.
