B010A01A-GAT FUEL RECOMMENDATIONS Use Unleaded Gasoline Unleaded gasoline with a Pump Octane Rating of 87 (Research Octane Number 91) or highermust be used in Hyundai vehicle. If leaded gaso-line is used, it will cause the catalytic converter tobecome ineffective and the emission controlsystem to malfunction.This can also result in increased maintenanceexpense. To avoid accidental use of leaded fuel,the larger nozzle used with leaded gasoline atservice stations can not be inserted into fuel tankopening of Hyundai vehicle. NOTE:
o For some countries, Hyundai vehicles are
designed to use leaded gasoline. Whenyou are going to use leaded gasoline, askto Hyundai dealer whether leaded gaso-line in your vehicle is available or not.
o Octane Rating of leaded gasoline is same with unleaded one.
B010B01A-AAT What About Gasohol? Gasohol (a mixture of 90% unleaded gasoline and 10% ethanol or grain alcohol) may be usedin your Hyundai. However, if your engine devel-ops drive ability problems, the use of 100%unleaded gasoline is recommended. Fuels withunspecified quantities of alcohol, or alcoholsother than ethanol, should not be used. B010D01S-AAT Do not Use Methanol Fuels containing methanol (wood alcohol) should
not be used in your Hyundai. This type of fuel canreduce vehicle performance and damage com-ponents of the fuel system. CAUTION: Your Hyundai's New Vehicle Limited War-ranty may not cover damage to the fuel sys-tem and performance problems that arecaused by the use of methanol or fuels con-taining methanol. B010E01A-AAT Gasolines for Cleaner AirTo help contribute to cleaner air, Hyundai recom- mends that you use gasolines treated with deter-gent additives, which help prevent deposit for-mation in the engine. These gasolines will helpthe engine run cleaner and the Emission ControlSystem performance. B010F01A-AAT Operation in Foreign Countries If you are going to drive your Hyundai in another country, be sure to:
o Observe all regulations regarding registra-
tion and insurance.
o Determine that acceptable fuel is available. B020A01X-GAT BREAKING IN YOUR NEW HYUNDAI During the First 2,000 km (1,200 Miles) No formal "break-in" procedure is required with your new Hyundai. However, you can contributeto the economical operation and durability of yourHyundai by observing the following recommen-
dations during the first 2,000 km (1,200 miles).
o Don't drive faster than 88 km/h (55 mph).
o While driving, keep your engine speed (rpm,
or revolutions per minute) between 2000 and4000 rpm.

B030B01A-AAT Record Your Key Number
AS10040A
A code number is stamped on the number plate that came with the keys to your Hyundai. Thiskey number plate should not be left with the keysbut kept in a safe place, not in the vehicle. Thekey number should also be recorded in a placewhere it can be found in an emergency.If you need additional keys, or if you should loseyour keys, your authorized Hyundai dealer canmake new keys if you can supply the key num-ber.
o For the first 300 km (200 miles), try to avoid
hard stops.
o Don't lug the engine (in other words, don't drive so slowly in too high a gear that the
engine "bucks" shift to a lower gear).
o Whether going fast or slow, vary your speed from time to time.
o Don't let the engine idle longer than 3 minutes for a catalytic converter-equipped engine.
B030A01A-AAT KEYS For greater convenience, the same key operates all the locks in your Hyundai. However, becausethe doors can be locked without a key, carryinga spare key is recommended in case you acci-dentally lock one key inside the car.
AS10030A
B880B03A-GAT Keys All of the locks fitted to the vehicle are operated by the same key. However, since it is possible tolock the doors without the use of the key, careshould be exercised to ensure that the key doesnot become locked inside the vehicle by mistake. NOTE: If you make your own duplicate key, you willnot be able to cancel the system or start theengine.

TROL SYSTEMS
H010A01A-GAT
EMISSION CONTROL SYSTEM (If Installed)
Your Hyundai is equipped with an emission
control system to meet all requirements of the Emission prohibition rules of your province. 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 main-tained by an authorized Hyundai dealer in ac-cordance with the maintenance schedule in thismanual. the crankcase through the air intake hose.Inside the crankcase, the fresh air mixes withblow-by gases, which then pass through thePCV valve and into the induction system.
H010C02A-GAT
2. Evaporative Emission Control
System (If installed)
The Evaporative Emission Control System is
designed to prevent fuel vapors from escapinginto the atmosphere. Canister
While the engine is inoperative, fuel vapors
generated inside the fuel tank are absorbed and stored in the onboard canister. When the en-gine is running, the fuel vapors absorbed in thecanister are drawn into the induction systemthrough
the purge control solenoid valve.
Purge Control Solenoid Valve The purge control solenoid valve is controlled
by the ECM; when the engine coolant temper-ature is low, and during idling, it closes, so thatevaporated fuel is not taken into the engine.After engine warm-up, during ordinary driving, itopens so as to introduce evaporated fuel to theengine.
H010B01A-AAT
1. Crankcase Emission Control Sys-
tem
The Positive Crankcase Ventilation System is
employed to prevent air pollution caused byblow-by gases being emitted from the crank-case. This system supplies fresh filtered air to H010D01A-AAT
3. Exhaust Emission Control System
The exhaust emission control system is a high-
ly effective system which controls exhaust emis-sion while maintaining good vehicle perfor-mance.
H020A01A-GAT
CATALYTIC CONVERTER (If Installed)
The catalytic converter is part of the exhaust
emission control system. It's purpose is to re-move certain engine emission products from
the engine's exhaust. It looks something like amuffler and is located underneath the car in theexhaust system. Catalytic Converter

EMISSION CONTROL SYSTEMS
7-2 o Do not touch the catalytic converter or any
other part of the exhaust system while the engine is running as it is very hot and couldresult in burns.
o Remember that your Hyundai dealer is your best source of assistance.
H020B01A-GAT
About the Catalytic Converter
Exhaust gases passing through the catalytic
converter cause it to operate at very high tem-peratures. As a result, the introduction of large
amounts of unburned gasoline may cause it to
overheat and create a fire hazard.
This can be avoided by observing the following:
o Use unleaded fuel only.
o Maintain your engine in good condition. Ex- tremely high converter temperatures can result from improper operation of the electri-cal, ignition or fuel injection systems.
o If your engine stalls, pings, knocks, or is hard to start, take your car to your Hyundaidealer as soon as possible and have thedifficulty corrected.
o Avoid driving with a very low fuel level. If you run out of gasoline, it could cause the engineto misfire and result in excessive loading of
the catalytic converter.
o Avoid idling the engine for periods longer than 10 minutes.
o Your Hyundai should not be either pushed or pulled to get it started.This can cause the catalytic converter tooverload.
o Take care not to stop your Hyundai over any combustible material such as grass, paper,leaves or rags. As these materials could
come in contact with the catalytic converterand could cause a fire.
