Checking the Air Conditioning Operation
1. Start the engine and let it run at a fast idle for
several minutes with the air conditioning set at the maximum cold setting.
2. If the air coming out of the in-dash vents is not cold, have the air conditioning systeminspected by your Hyundai dealer.
CAUTION: Running the air conditioning system for extended periods of time with a low refriger-ant level may damage the compressor. G140C01A-AAT
Lubrication To lubricate the compressor and the seals in the system, the air conditioning should be runfor at least 10 minutes each week. This isparticularly important during cool weather whenthe air conditioning system is not otherwise inuse.
G150A01A-GAT
CHECKING STEERING WHEEL FREEPLAY
To check the steering wheel freeplay, stop the
car with the wheels pointed straight ahead and gently move the steering wheel back and forth.Use very light finger pressure and be sensitiveto changes in resistance that mark the limits ofthe freeplay. If the freeplay is greater thanspecified, have it inspected by your Hyundaidealer and adjusted or repaired if necessary.

G140D01S-GAT
Checking the Compressor Drive Belt
When the air conditioning is being used regular- ly, the compressor drive belt tension should bechecked at least once a month. To check the drive belt tension, press down on the belt halfway between the engine crankshaftand compressor pulleys. Pressing with yourfinger, you should not be able to deflect this beltanymore than 8.0 mm. If you have the instru-ments to check it with a force of 98N (22 lb.),the deflection should be approx. 8.0 mm (0.315in.). If the belt is too loose, have it adjusted byyour Hyundai dealer.

POWER STEERING HOSES
It is suggested that you check the power steer-
ing hose connections for fluid leakage at regular intervals. The power steering hoses should bereplaced if there is severe surface cracking,scuffing or worn spots. Deterioration of thehose could cause premature failure. NOTE: Grinding noise from the power steering
pump may be heard immediately after the engine is started in extremely cold condi-tions (below - 20°C). If the noise stops dur-ing warm up, there is no abnormal functionin the system. It is due to a power steeringfluid characteristic in extremely cold condi-tions.
Recommended Fluid Use PSF-3 type fluid NOTE: Do not start the engine when the power
steering oil reservoir is empty. G300A01B-GAT
REMOVAL OF WATER FROM THE FUEL FILTER (DIESEL ENGINE)
If the fuel filter warning light illuminates during driving, it indicates that water has accumulatedin the fuel filter. If this occurs, remove the wateras described below.

POWER STEERING FLUID LEVEL
HFC5004
Gasoline engine
The power steering fluid level should be checked
regularly.
To check the power steering fluid level, be sure
the ignition is "OFF", then check to make cer- tain that the power steering fluid level is be-tween the "MAX" and "MIN" level markings onthe fluid reservoir.

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 largeamounts of unburned gasoline may cause it tooverheat and create a fire hazard. This can beavoided 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 your run out of gasoline, it could cause theengine to misfire and result in excessiveloading 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 thecatalytic 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 converterand could cause a fire. o Do not touch the catalytic converter or any
other part of the exhaust system while theengine is running as it is very hot and couldresult in burns.
o Remember that your Hyundai dealer is your best source of assistance.
H020D01S-GAT
CATALYTIC CONVERTER ; For a diesel engine
All Hyundai vehicles are equipped with oxida- tion type catalytic converter to reduce the car-bon monoxide, hydrocarbons and particulatecontained in the exhaust gas.
H020C01S-GAT
EGR SYSTEM ; For a diesel engine
This system helps control oxides of nitrogen by recirculating a part of the exhaust gas into theengine.

CONTROLS AND EQUIPMENT
from jerry cans or by means of a funnel that the fuel being used is unleaded.The use of leaded fuel in this vehicle will result in irreversible pollution of the catalyst ele- ment. Such pollution will prevent correct op- eration of the catalyst and give rise to in- creased operating temperatures leading to the catalyst element melting and restricting the exhaust flow along with an increase in exhaust emission levels. CAUTION: The vehicle warranty will not extend to damage arising from the use of incorrect fuels. Use Diesel Diesel fuel of 52 to 54 cetane is the correct rating to use in Hyundai vehicle. If two types of diesel fuel are available, use summer or winter fuel properly according to the following temperature conditions.
o Above 23°F (-5°C) ... Summer type diesel fuel.
o Below 23°F (-5°C) ... Winter type diesel fuel. Watch the fuel level in the tank very carefully: If the engine stops through fuel failure, thecircuits must be completely purged to permit restarting.

B010A02O-EAT FUEL RECOMMENDATIONSTHIS VEHICLE MUST ONLY BE OPERATED WITH UNLEADED FUEL.SERIOUS DAMAGE WILL RESULT FROM THE USE OF LEADED FUEL.
UNLEADED FUEL ONLY
Unleaded fuel with a Research Octane Num-ber (RON) of 91 or higher must be used in this vehicle. To prevent accidental charging of the fueltank with leaded fuel, a small diameter filler neck along with a restrictor flap are fitted to ensure that only unleaded fuel pump nozzles may enter the filler neck. However, care must be exercised when refuelling the vehicle tank SB010E1-A GASOLINES FOR CLEANER AIRTo help contribute to cleaner air, Hyundai recommends that you use gasolines treated with detergent additives, which help to pre- vent deposit formation in the engine. These gasolines will help the engines run cleaner and the Emission Control System performance.
CAUTION:Do not let any gasoline or water enter thetank. If this happens, the tank should be completely drained and the fuel lines should all be cleaned out. This will stop the fuel pump from becoming contami- nated. Overseas Operation: When the vehicle is to be operated overseas, the vehicle operator should establish that a suitable fuel for satisfactory operation of the vehicle is available.
