FUEL RECOMMENDATIONS
CAUTION:
Your Hyundai's New Vehicle Limited War-
ranty may not cover damage to the fuel
system and any performance problems
that are caused by the use of fuels con-
taining methanol or fuels containing
MTBE (Methyl Tertiary Butyl Ether) over
15.0% vol. (Oxygen Content 2.7% weight.)
B010B01A-AATWhat About Gasohol?Gasohol (a mixture of 90% unleaded
gasoline and 10% ethanol or grain alcohol)
may be used in your Hyundai. However, if
your engine develops driveability
problems, the use of 100% unleaded
gasoline is recommended. Fuels with
unspecified quantities of alcohol, or
alcohols other than ethanol, should not be
used.
B010A02NF-AATUse Unleaded GasolineUnleaded gasoline with a Pump Octane
Rating of 87 (Research Octane Number
91) or higher must be used in your
Hyundai.
B010C01A-AATUse of MTBEHyundai recommends that fuels
containing MTBE (Methyl Tertiary Butyl
Ether) over 15.0% vol. (Oxygen Content
2.7% weight) should not be used in your
Hyundai.
Fuel containing MTBE over 15.0% vol.
(Oxygen Content 2.7% weight) may reduce
vehicle performance and produce vapor
lock or hard starting.
B010D01A-AATDo Not Use MethanolFuels containing methanol (wood alcohol)
should not be used in your Hyundai. This
type of fuel can reduce vehicle
performance and damage components of
the fuel system.

B290A03A-AATENGINE COOLANT TEMPERATURE
GAUGE
WARNING:Never remove the radiator cap when the
engine is hot. The engine coolant is under
pressure and could erupt and cause
severe burns. Wait until the engine is
cool before adding coolant to the
reservoir.The normal range is approximately in the
middle between "H" and "C". If it moves
across the dial to "H" (HOT), pull over and
stop as soon as possible and turn off the
engine. Then open the hood and, after the
engine has cooled, check the coolant level
(See "If the engine overheats" on the page
3-4.) and the water pump drive belt. If you
suspect cooling system trouble, have your
cooling system checked by a Hyundai dealer
as soon as possible.

WARNING:
- When using a portable fuel container,
be sure to place the container on the
ground while refueling. Static elec-
tricity discharge from the container
can ignite fuel vapors causing a fire.
While starting refueling, contact
should be maintained until the filling
is complete.
- Do not use cellular phones around a
gas station. The electric current or
electronic interference from cellular
phones can ignite fuel vapors caus-
ing a fire.
- When refueling, always turn the en-
gine off. Sparks by engine compart-
ment electrical equipment can ignite
fuel vapors causing a fire. After re-
fueling, check to make sure the fuel
filler cap is securely closed, and
then start the engine.
- Do not smoke or try to light cigarettes
around a gas station. Automotive
fuels are flammable.
o After refueling, make sure the fuel
cap is installed securely to prevent
fuel spillage in the event of an accident
o Tighten the cap until it clicks, otherwise
the "
" light will illuminate
o If you open the fuel filler cap during
high ambient temperatures, a slight
"pressure sound" may be heard. This
is normal and not a cause for concern.
Whenever you open the fuel filler cap,
turn it slowly.
o Do not "top off" after the nozzle auto-
matically shuts off when refueling.
o Automotive fuels are flammable/ex-
plosive materials. When refueling,
please note the following guidelines
carefully.
- Before touching the fuel nozzle or
fuel filler cap, have one's hands in
contact with metal parts away from
the filler neck to discharge static
electricity.
- Do not get back in the vehicle while
refueling. Do not operate anything
that can produce static electricity.
Static electricity discharge can ignite
fuel vapors resulting in an explosion.

EMISSION CONTROL SYSTEMS2
EMISSION CONTROL
SYSTEMS
H010B01A-AAT1. Crankcase Emission Control Sys-
temThe positive crankcase ventilation system
is employed to prevent air pollution caused
by blow-by gases being emitted from the
crankcase. This system supplies fresh
filtered air to the crankcase through the air
intake hose. Inside the crankcase, the fresh
air mixes with blow-by gases, which then
pass through the PCV valve into the
induction system.
CanisterFuel 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 solenoid 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 evaporated 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.H010D01A-AAT3. Exhaust Emission Control
SystemThe Exhaust Emission Control System is a
highly effective system which controls
exhaust emissions while maintaining good
vehicle performance.
H010A01NF-AATYour Hyundai is equipped with an emission
control system to meet all emission
regulations.
There are three emission control systems
which are as follows.
(1) Crankcase emission control system
(2) Evaporative emission control system
(3) Exhaust emission control system
In order to assure the proper function of the
emission control systems, it is
recommended that you have your car
inspected and maintained by an authorized
Hyundai dealer in accordance with the
maintenance schedule in this manual.
Caution for the Inspection and Mainte-
nance Test With Electronic Stability
Control (ESC) system
o To prevent the vehicle from misfiring
during dynamometer testing, turn the
Electronic Stability Control (ESC) sys-
tem off by pressing the ESC switch.
o After dynamometer testing is com-
pleted, turn the ESC system back on
by pressing the ESC switch again.
H010C01S-AAT2. Evaporative Emission Control (In-
cluding ORVR: Onboard Refueling
Vapor Recovery) SystemThe Evaporative Emission Control System
is designed to prevent fuel vapors from
escaping into the atmosphere.
(The ORVR system is designed to allow
the vapors from the fuel tank to be loaded
into a canister while refueling at the gas
station, preventing the escape of fuel
vapors into the atmosphere.)
