Introduction
"E85" fuel is an alternative fuel com-
prised of 85 percent ethanol and 15
percent gasoline, and is manufac-
tured exclusively for use in Flexible
Fuel Vehicles. “E85” is not compati-
ble with your vehicle. Use of “E85”
may result in poor engine perform-
ance and damage to your vehicle’s
engine and fuel system. HYUNDAI
recommends that customers do not
use fuel with an ethanol content
exceeding 10 percent.
To prevent damage to your vehicle’s
engine and fuel system:
Never use gasohol which con- tains methanol.
Never use gasohol containing more than 10% ethanol.
Never use leaded fuel or leaded gasohol.
Never use "E85" fuel.
Your New Vehicle Limited
Warranty does not cover damage
to the fuel system or any perform-
ance problems caused by the use
of "E85" fuel.
Other fuels
Using fuels such as;
- Silicone (Si) contained fuel,
- Ferrocene (Fe) contained fuel, and
- Other metallic additives contained fuels,
may cause damage to the engine by
plugging, misfiring, poor accelera-
tion, engine stalling, catalyst melting,
abnormal corrosion, life cycle reduc-
tion.
- The Malfunction Indicator Lamp (MIL) may illuminate.
Damage to the fuel system or per-
formance problem caused by the
use of these fuels may not be cov-
ered by your New Vehicle Limited
Warranty.
Gasoline containing MMT
Some gasoline contains harmful
manganese-based fuel additives
such as
MMT (Methylcyclopentadienyl
Manganese Tricarbonyl
).
HYUNDAI does not recommend the
use of gasoline containing MMT.
This type of fuel can reduce vehicle
performance and affect your emis-
sion control system.
The malfunction indicator lamp on
the cluster may come on.
Fuel Additives
HYUNDAI recommends that you use
good quality gasolines treated with
detergent additives such as TOP TIER
Detergent Gasoline, which help pre-
vent deposit formation in the engine.
These gasolines will help the engine
run cleaner and enhance performance
of the Emission Control System. For
more information on TOP TIER
Detergent Gasoline, please go to the
website (www
.toptiergas.com).

Battery replacement
If the Smart Key is not working prop-
erly, try replacing the battery with a
new one.
Battery Type: CR2032
To replace the battery:
1. Pry open the rear cover of thesmart key.
2. Remove the old battery and insert the new battery.
3. Reinstall the rear cover of the smart key. If you suspect your smart key might
have sustained some damage, or
you feel your smart key is not work-
ing correctly, contact an authorized
HYUNDAI dealer.
Information
An inappropriately disposed
battery can be harmful to the
environment and human
health. Dispose the battery
according to your local law(s)
and regulation(s).
Immobilizer System
The immobilizer system protects your
vehicle from theft. If an improperly
coded key (or other device) is used,
the engine’s fuel system is disabled.
When the ignition switch is placed in
the ON position, the immobilizer sys-
tem indicator should come on briefly,
then go off. If the indicator starts to
blink, the system does not recognize
the coding of the key.
Place the ignition switch to the
LOCK/OFF position, then place the
ignition switch to the ON position again.
The system may not recognize your
key’s coding if another immobilizer
key or other metal object (i.e., key
chain) is near the key. The engine
may not start because the metal may
interrupt the transponder signal from
transmitting normally.
If the system repeatedly does not
recognize the coding of the key, it is
recommended that you contact your
HYUNDAI dealer.

Fuel Gauge
This gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.
Information
• The fuel tank capacity is given inchapter 8.
• The fuel gauge is supplemented by a low fuel warning light, which will
illuminate when the fuel tank is
nearly empty.
• On inclines or curves, the fuel gauge pointer may fluctuate or the low fuel
warning light may come on earlier
than usual due to the movement of
fuel in the tank.
Avoid driving with an extremely
low fuel level. Running out of fuel
could cause the engine to misfire,
damaging the catalytic converter.
Odometer
The odometer indicates the total dis-
tance that the vehicle has been driv-
en and should be used to determine
when periodic maintenance should
be performed.
- Odometer range : 0 ~ 999999 miles or kilometers.
