2FUEL RECOMMENDATIONS
B010A01MC-GAT Use Unleaded Gasoline If leaded gasoline is used, it will cause the catalytic converter to become inef-fective and the emission control sys- tem to malfunction. This can also result in increased maintenance expense. Toavoid accidental use of leaded fuel, the large nozzle used with leaded gasoline at service stations can not be insertedinto fuel tank opening of Hyundai ve- hicle. NOTE:
o For some countries, Hyundai ve-
hicles are designed to use leaded gasoline. When you are going touse leaded gasoline, ask to Hyundai dealer whether leaded gasoline in your vehicle is avail-able or not.
o Octane Rating of leaded gasoline
is same with unleaded one.
Use Diesel Diesel fuel of 52 to 54 cetane is used in Hyundai vehicle. If two types of diesel fuel are available, use summer or winterfuel properly according to the following temperature conditions.
For Europe
– For the optimal vehicle
performance, we recommend you touse unleaded gasoline with an octane rating of RON (Research Octane Num-ber) 95 /AKI (Anti Knock Index) 91 or higher. You may use unleaded gasoline with anoctane rating of RON 91~94/AKI 87~90 but it may result in slight performance reduction of the vehicle. Except Europe – Unleaded gasoline
with a Pump Octane Rating of 87 (Re- search Octane Number 91) or higher must be used in Hyundai vehicle. CAUTION:
o Do not let any gasoline or water enter the tank. This would make it necessary to drain it out and tobleed the lines to avoid jamming the injection pump and damaging the engine.
o In winter, in order to cut down incidents due to freezing, paraffinoil may be added to the fuel if thetemperature drops to below -10°C. Never use more than 20% paraffin oil.
!
B010A01MC o Above -5°C (23°F) ... Summer type
diesel fuel.
o Below -5°C (23°F) ... Winter type diesel fuel.
Watch the fuel level in the tank very carefully : If the engine stops throughfuel failure, the circuits must be com- pletely purged to permit restarting.

B260J01S-GAT Charging System Warning Light
The charging system warning light should come on when the ignition isturned on, then go out when the engine is running. If the light stays on while the engine is running, there is a malfunctionin the electrical charging system. If the light comes on while you are driving, stop, turn off the engine and checkunder the hood. First, make certain the generator drive belt is in place. If it is, check the tension of the belt.And then, have the system checked by your Hyundai dealer.
CAUTION:
If the drive belt (generator belt) is loosen, broken, or mission while the vehicle is driving, there may be a serious malfunction, engine couldoverheat because this belt also drives the water pump.! B260M01A-AAT
Low Fuel Level Warning Light
The low fuel level warning light comes on when the fuel tank is approachingempty. When it comes on, you should add fuel as soon as possible. Driving with the fuel level warning light on orwith the fuel level below "E" can cause the engine to misfire and damage the catalytic converter.

Engine Coolant Tempera-
ture Indicator Light
(If Installed)
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 untilthe engine is cool before removing the radiator cap.
!
These indicator lights show the tem- perature of the engine coolant when the ignition switch is ON. Red indicator light illuminates if the temperature of theengine coolant is above 123±3°C (253.4±37.4°F). Blue indicator light Illu- minates if the temperature of the enginecoolant is below 55±3°C (131±37.4°F). If the red indicator light illuminates, pull over and stop as soon as possible andturn off the engine. Then open the hood and check the coolant level (See "If the engine overheats" on the page 3-4.) andthe water pump drive belt. If you sus- pect cooling system trouble, have your cooling system checked by a Hyundaidealer as soon as possible.
If the Emission Control SystemMalfunction Indicator Light beginsto flash ON and OFF, potential catalytic converter damage is pos- sible which could result in loss ofengine power. Have the Engine Control System inspected as soon as possible by an authorizedHyundai dealer (Gasoline Engine).
o In case the injection quantity ad-
justment related error occurred,the Emission Control System Mal- function Indicator Light begins to flash ON and OFF. Continuousdriving with this status could re- sult in abnormal engine power loss (or power increase), combus-tion noise and poor emission. If this occurs, have your vehicle checked by an authorized Hyundaidealer (Diesel Engine).
B260N01MC-GAT Malfunction Indicator Light (If Installed)
This light illuminates when there is a malfunction of an exhaust gas relatedcomponent, and the system is not func- tioning properly so that the exha ust gas
regulation values are not satisfied. This light will also illuminate when the ignition
key is turned to the "ON" position, and then it will go out in a few seconds after
the engine is started. If it illuminates
while driving, or does not illuminate whenthe ignition key is turned to the "ON"position, take your car to your nearest authorized Hyundai dealer and have the system checked.
CAUTION:
o Prolonged driving with the Emis- sion Control System Malfunction Indicator Light illuminated may cause damage to the emission control systems which could ef-fect drivability or fuel economy.!

CATALYTIC CONVERTER
H020A01A-GAT
(If Installed) ; For a gasoline engine
H020A01MC
The catalytic converter is part of the exhaust emission control system. Itspurpose is to remove certain engine emission products from the engine's exhaust. It looks something like amuffler and is located underneath the car in the exhaust system.
Catalytic Converter H020B01A-GAT
About the Catalytic Converter
Exhaust gases passing through the
catalytic converter cause it to operate at very high temperatures. As a re- sult, the introduction of large amountsof unburned gasoline may cause it to overheat and create a fire hazard. This can be avoided by observing thefollowing:
WARNING:
o Use unleaded fuel only.
o Maintain your engine in good condition. Extremely high con-verter temperatures can result from improper operation of the electrical, ignition or fuel injec-tion systems.
o If your engine stalls, pings, knocks, or is hard to start, takeyour car to your Hyundai dealer as soon as possible and have the difficulty corrected.
o Avoid driving with a very low fuel
level. If your run out of gasoline, it could cause the engine to mis- fire and result in excessive load- ing of the catalytic converter.
o Avoid idling the engine for peri-
ods longer than 10 minutes.
o Your Hyundai should not be ei- ther pushed or pulled to get itstarted. This can cause the cata-lytic converter to overload.
o Take care not to stop your Hyundai over any combustible material such as grass, paper, leaves or rags. As these materials couldcome in contact with the catalytic converter and could cause a fire.
o Do not touch the catalytic con- verter or any other part of theexhaust system while the en- gine is running as it is very hotand could result in burns.
o Remember that your Hyundai dealer is your best source of assistance.

; For a diesel engine
This system helps control oxides of nitrogen by recirculating a part of the exhaust gas into the engine.
H020D01S-GAT
CATALYTIC CONVERTER ; For a diesel engine
All Hyundai vehicles are equipped
with oxidation type catalytic converter to reduce the carbon monoxide, hy- drocarbons and particulate containedin the exhaust gas.
