Introduction
Your new KIA vehicle is designed to use
only unleaded fuel having a pump octane
number ((R+M)/2) of 87 (Research
Octane Number 91) or higher.
Your new vehicle is designed to obtain
maximum performance with UNLEADED
FUEL, as well as minimize exhaust emis-
sions and spark plug fouling.Gasoline containing alcohol andmethanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alcohol),
and gasoline or gasohol containing
methanol (also known as wood alcohol)
are being marketed along with or instead
of leaded or unleaded gasoline.
Do not use gasohol containing more than
10% ethanol, and do not use gasoline or
gasohol containing any methanol. Either
of these fuels may cause drivability prob-
lems and damage to the fuel system.
Discontinue using gasohol of any kind if
drivability problems occur.
Vehicle damage or drivability problems
may not be covered by the manufactur-
er’s warranty if they result from the use
of:
1. Gasohol containing more than 10% ethanol.
2. Gasoline or gasohol containing methanol.
3. Leaded fuel or leaded gasohol. "E85" fuel is an alternative fuel com-
prised of 85 percent ethanol and 15 per-
cent gasoline, and is manufactured
exclusively for use in Flexible Fuel
Vehicles. “E85” is not compatible with
your vehicle. Use of “E85” may result in
poor engine performance and damage to
your vehicle's engine and fuel system.
KIA recommends that customers do not
use fuel with an ethanol content exceed-
ing 10 percent.
FUEL REQUIREMENTS
CAUTION

Features of your vehicle
Immobilizer system (if equipped)
Your vehicle may be 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 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 if the ignition
key is valid or not.
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 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.
To deactivate the immobilizer sys-tem:
Insert the ignition key into the key cylin-
der and turn it to the ON position.
✽ ✽ 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.
✽ ✽NOTICE
If you need additional keys or lose your
keys, consult an authorized KIA dealer.
WARNING
Use only KIA original parts for the
ignition key in your vehicle. If an
aftermarket key is used, the ignition
switch may not return to ON after
START. If this happens, the starter
will continue to operate causing
damage to the starter motor and
possible fire due to excessive cur-
rent in the wiring.
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.
CAUTION
Do not put metal accessories near
the ignition switch. Metal acces- sories may interrupt the transpon-der signal and may prevent the engine from being started.
CAUTION
The transponder in your ignitionkey is an important part of theimmobilizer system. It is designedto give years of trouble-free service, however you should avoid expo-sure to moisture, static electricity and rough handling. Immobilizersystem malfunction could occur.

Features of your vehicle
(Continued)
If a fire breaks out during refuel-ing, leave the vicinity of the vehi-
cle, and immediately contact the
manager of the gas station and
then contact the local fire depart-
ment. Follow any safety instruc-
tions they provide.(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)CAUTION
Make sure to refuel your vehicleaccording to the "Fuel require-ments" suggested in section 1.
If the fuel filler cap requires replacement, use only a genuineKIA cap or the equivalent speci-fied for your vehicle. An incorrect fuel filler cap can result in a seri-ous malfunction of the fuel sys- tem or emission control system.
Do not spill fuel on the exterior surfaces of the vehicle. Any typeof fuel spilled on painted surfacesmay damage the paint.
After refueling, make sure the fuel cap is installed securely to pre-vent fuel spillage in the event ofan accident.

Electric power steering
Power steering uses the motor 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.
The motor driven power steering is con-
trolled by the power steering control unit
which senses the steering wheel torque
and vehicle speed to command the
motor.
The steering wheel becomes heavier as
the vehicle’s speed increases and
becomes lighter as the vehicle’s speed
decreases for better control of the steer-
ing wheel.
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
The following symptoms may occur dur-
ing normal vehicle operation:
• The EPS warning light does not illumi-
nate.
• The steering effort is high immediately after turning the ignition switch on.
This happens as the system performs
the EPS system diagnostics. When the
diagnostics is completed, the steering
wheel will return to its normal condi-
tion.
• A click noise may be heard from the EPS relay after the ignition switch is
turned to the ON or LOCK position.
• Motor noise may be heard when the vehicle is at a stop or at a low driving
speed.
• If the Electric Power Steering System does not operate normally, the warn-
ing light will illuminate on the instru-
ment cluster. The steering wheel may
become difficult to control or operate
abnormally. Take your vehicle to an
authorized Kia dealer and have the
vehicle checked as soon as possible.
• The steering effort increases if the steering wheel is rotated continuously
when the vehicle is not in motion.
However, after a few minutes, it will
return to its normal conditions. • When you operate the steering wheel
in low temperature, abnormal noise
could occur. If temperature rises, the
noise will disappear. This is a normal
condition.

system may not work normally. Have the
vehicle checked by an authorized KIA
dealer as soon as possible.
WARNING
If both ABS and Brake warning
lights are on and stay on, your vehi-
cle’s brake system will not work
normally during sudden braking. In
this case, avoid high speed driving
and abrupt braking. Have your vehi-
cle checked by an authorized KIA
dealer as soon as possible.
