Other fuels
Using fuels such as,- Silicone (Si) contained fuel,
- Ferrocene (Fe) contained fuel, and - Other metallic additives contained fuels,
may cause vehicle and engine dam-
age. Also the Malfunction Indicator
Lamp (MIL) may illuminate or cause
plugging, misfiring, poor accelera-
tion, engine stalling, catalyst melting,
abnormal corrosion, life cycle reduc-
tion, etc.
✽ ✽ NOTICE
Damage to the fuel system or per-
formance problem caused by the use
of these fuels may not be covered by
your New Vehicle Limited
Warrenty.
Gasoline containing MMT
Some gasoline contains harmful man-
ganese-based fuel additives such as
MMT (Methylcyclopentadienyl Man-
ganese 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.
Do not use methanol
Fuels containing methanol (wood
alcohol) should not be used in your
vehicle. This type of fuel can reduce
vehicle performance and damage
components of the fuel system,
engine control system and emission
control system.
Fuel Additives
HYUNDAI 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 per-
formance of the Emission Control
System. For more information on TOP
TIER Detergent Gasoline, please go
to the website (www.toptiergas.com).
For customers who do not use TOP
Tier Detergent Gasoline regularly,
and have problems starting or the
engine does not run smoothly, addi-
tives that you can buy separately
may be added to the gasoline. If TOP
TIER Detergent Gasoline is not avail-
able, one bottle of additive added to
the fuel tank at every 7,500 miles or
every engine oil change is recom-
mended. Additives are available from
your authorized HYUNDAI dealer
along with information on how to use
them. Do not mix other additives.
CAUTION
Your New Vehicle Limited
Warranty may not cover damageto the fuel system and any per-formance problems that arecaused by the use of fuels con-taining methanol.

Maintenance
Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in
the canister are drawn into the surge
tank through the purge control sole-
noid valve.
Purge Control Solenoid Valve(PCSV)
The purge control solenoid valve is
controlled by the Engine Control
Module (ECM); when the engine
coolant temperature is low during
idling, the PCSV closes so that evap-
orated fuel is not taken into the
engine. After the engine warms-up
during ordinary driving, the PCSV
opens to introduce evaporated fuel to
the engine.
3. Exhaust emission control system
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
while maintaining good vehicle per-
formance.
When the engine starts or fails to
start, excessive attempts to restart
the engine may cause damage to the
emission system.
Vehicle modifications
This vehicle should not be modi-
fied. Modification of your vehicle
could affect its performance, safety
or durability and may even violate
governmental safety and emis-
sions regulations.
In addition, damage or performance
problems resulting from any modifi-
cation may not be covered under
warranty.
If you use unauthorized electronic devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic devices.
Engine exhaust (carbon monox-
ide) precautions
Carbon monoxide can be present with other exhaust fumes. If you
smell exhaust fumes of any kind in
your vehicle, drive with all the win-
dows fully open. Have your vehicle
checked and repaired immediately.
WARNING
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
on this page to avoid CO poi-
soning.
