Introduction  
Fuel requirements  
Your new vehicle is designed to use only  
unleaded fuel having a pump octane  
number ((R+M)/2) of 87 (Research  
Octane Number 91) or higher. (Do not  
use methanol blended fuels.)  
Your new vehicle is designed to obtain  
maximum performance with UNLEADED  
FUEL, as well as minimize exhaust emis  
sions and spark plug fouling.  
Never add any fuel system cleaning  
agents to the fuel tank other than what  
has been specified. (Consult an autho  
rized Kia dealer for details.)

otherwise the Check Engine light will  
illuminate.  
Either of these fuels may cause drivabil

ity problems and damage to the fuel  
system, engine control system and emis

sion control system.  
Discontinue using gasohol of any kind if  
drivability problems occur.  
Vehicle damage or drivability problems  
may not be covered by the manufac

turer's warranty if they result from the  
use of:  
-
1. Gasoline or gasohol containing meth

2. Leaded fuel or leaded gasohol.  
3. Gasohol containing more than 15%  
ethanol.

WARNING  
Refueling  
僅 Do not "top off" after the nozzle auto  
matically shuts off. Attempts to force  
more fuel into the tank can cause fuel  
overflow onto you and the ground,  
causing a risk of fire.  
"E85" may result in poor engine perfor

tained fuel, and other metallic additives,  
may cause vehicle and engine damage  
or cause misfiring, poor acceleration,  
engine stalling, catalyst melting, clog  
ging, abnormal corrosion, life cycle

Also, the Malfunction Indicator Lamp  
(MIL) may illuminate.

Do not use methanol  
Fuels containing methanol (wood alco

hol) should not be used in your vehicle.  
This type of fuel can reduce vehicle per  
formance and damage components of  
the fuel system, engine control system  
and emission control system.

NOTICE  
Damage to the fuel system or perfor  
mance problems caused by the use of  
these other fuels may not be covered by  
your New Vehicle Limited Warranty.

Fuel Additives  
Kia recommends that you use good  
quality gasolines treated with detergent  
additives such as TOP TIER Detergent  
Gasoline, which help prevent deposit  
formation in the engine. These gasolines  
will help the engine run cleaner and  
enhance performance of the emission  
control system.  
Use of MTBE  
Kia recommends avoiding fuels contain  
ing MTBE (Methyl Tertiary Butyl Ether)  
over 15.0% vol. (Oxygen Content 2.7%  
weight) in your vehicle.  
-
Fuel containing MTBE over 15.0% vol.  
(Oxygen Content 2.7% weight) may  
reduce vehicle performance and pro  
duce vapor lock or hard starting.  
For more information on TOP TIER

Your New Vehicle Limited Warranty may  
not cover damage to the fuel system  
and any performance problems that are  
caused by the use of fuels containing  
methanol or fuels containing MTBE  
(Methyl Tertiary Butyl Ether) over 15.0%  
vol. (Oxygen Content 2.7% weight.)  
separately may be added to the gaso  
line.  
-
If TOP TIER Detergent Gasoline is not  
available, one bottle of additive should  
be added to the fuel tank at every  
13,000 km (8,000 miles) or every  
engine oil change is recommended.  
Additives are available from your autho  
rized Kia dealer along with information
