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 (0.315inches). If the belt is too loose, have it adjustedby your Hyundai dealer. A/C

Checking the Air Conditioning Opera- tion
1. Start the engine and let it run at 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.
G130B02A-AAT
To Replace the Fluid
Recommended brake fluid conforming to DOT
3 or DOT 4 specification should be used. Thereservoir cap must be fully tightened to avoidcontamination from foreign matter or moisture.
NOTE: Do not allow any other liquids to contami-
nate the brake fluid. Seal damage will result.
WARNING:Use caution when handling brake fluid. It
can damage your vision if you get it in your eyes. It will also damage your vehicle's paintif spilled on it and not removed immediately.
G140A01A-AAT
AIR CONDITIONING CARE Keeping the Condenser Clean
The air conditioning condenser (and engine
radiator) should be checked periodically for accumulation of dirt, dead insects, leaves, etc.These can interfere with maximum cooling effi-ciency. When removing such accumulations,brush or hose them away carefully to avoidbending the cooling fans.

POWER STEERING HOSES It is suggested that you check the power steer-
ing hose connections for fluid leakage daily. The power steering hoses should be replaced ifthere is severe surface cracking, pulling, scuff-ing or worn spots. Deterioration of the hosecould cause premature failure. G250A01A-AAT
FOR MORE INFORMATION ABOUT YOUR HYUNDAI
If you desire additional information about main- taining and servicing your Hyundai, you maypurchase a factory Shop Manual at your Hyundaidealer's parts department. This is the samemanual used by dealership technicians andwhile it is highly technical it can be useful inobtaining a better understanding of your carand how it works.
G230A03A-GAT
POWER STEERING FLUID LEVEL
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.
NOTE: Grinding noise from the power steering
pump may be heard immediately after the engine is started in extremely cold condi-tions (below - 20°F). If the noise stops dur-

Checking Condenser Cooling Fan
The condenser coolant fan should come on
automatically whenever the air conditioning is in operation. 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.
G210B01A-AAT
Checking the Battery Keep the battery clean. Any evidence of corro-
sion around the battery posts or terminals shouldbe removed using a solution of household bak-ing soda and warm water. After the batteryterminals are dry, cover them with a light coat-ing of grease.
G220A01A-AAT
CHECKING ELECTRIC COOLING FANS WARNING: The cooling fan is controlled by engine cool-
ant temperature and may sometimes oper- ate even when the engine is not running.Use extreme caution when working near theblades of the coolant fan, so that you are notinjured by a rotating fan blade. As the cool-ant temperature decreases the fan will auto-matically shut off. This is a normal condi-tion.
G220B01A-AAT
Checking Engine Cooling Fan The engine coolant fan should come on auto-
matically if the engine coolant temperature ishigh.
o Charge batteries only in a well ventilated
area.
o Do not permit flames, sparks or smoking in the area.
o Keep children away from the area.

SB215B1-E ENGINE COOLANT TEMPERATURE GAUGE engine is hot may cause hot water and steam to be ejected from the radiator resulting inburns and scalding. The radiator cap mustonly be removed when the engine has cooled.Do not add cold water to a hot engine to avoidthe possibility of engine damage. The use ofplain water in the cooling system is not rec-ommended since the aluminium componentsof the cooling system require the use of acorrosion inhibitor found in the recommendedEthylene Glycol type anti freeze solutions.
The engine coolant temperature gauge indicatesthe engine coolant temperature and will, undernormal circumstances, give an indication in the"Normal" or centre portion of the scale. Shouldthe indication move into the upper or "Hot" por-tion of the scale, engine overheating is indicated.Under these circumstances, the vehicle shouldbe brought to rest as soon as is safe to do so andthe engine turned off. Once the engine has cooledsomewhat, the coolant level and the condition ofthe generator/water pump drive belt should bechecked. If the cause of the overheating cannotbe readily established, the assistance of aHyundai dealer should be sought. WARNING: The engine cooling system is pressurizedand removal of the radiator cap when the The tachometer registers the speed of the enginein revolutions per minute (R.P.M.). CAUTION: The maximum safe engine operating speed isindicated by the white zone of the tachometerscale. The engine should not be operatedbeyond the beginning of this zone or seriousengine damage may result.

o To direct all intake air to the dashboard vents, set the airflow control to "Face".
o Adjust the fan speed control to the desired speed.
o Set the temperature control between "Cool" and "Warm".
B710C01S-AAT SIDE VENTILATORThe side ventilators are located on each side of dashboard. To change the direction of the airflow, move the knob in the center of the vent up-and-down and side-to-side. The side vent knobscontrol the amount of outside air entering thevehicle through the side vents. The vents areopened when the vent knob is moved to the upposition. The vents are closed when the ventknob is moved to the down position. Keep thesevents clear of any obstructions.

B690A01S-AAT HEATING CONTROLSFor normal heating operation, set the air intake control to the "Fresh" position and the air flowcontrol to "Floor". For faster heating, the air intake control should be in the "Recirculation" position. If the windows fog up, move the air flow control to the "Def" (defroster) position. (The A/C will be onautomatically and it will be changed to "Fresh"mode.) For maximum heat, move the temperature con- trol to "Warm".
B730A01FC-EAT Operation Tips
o To keep dust or unpleasant fumes from enter-
ing the car through the ventilation system, temporarily set the air intake control at "Recir-culation". Be sure to return the control to"Fresh" when the irritation has passed tokeep fresh air in the vehicle. This will helpkeep the driver alert and comfortable.
o Air for the heating/cooling system is drawn in through the grilles just ahead of the wind-screen. Care should be taken that these arenot blocked by leaves, snow, ice or otherobstructions.
o To prevent interior fog on the windscreen, set the air intake control to the fresh air ( )position and fan speed to the desi-red posi-tion.
NOTE:When the A/C is operated continuously onthe floor-defrost level (
) or defrost level
(), it may cause fog to form on the exterior
windscreen by the temperature differential. At this time set the air flow control to the facelevel position (
)and fan speed control to the
low position.
Use the heating/ventilation system to defrost or defog the windscreen: To remove the interior fog on the windscreen;
o Set the air flow control to the defrost (
)
position. (The A/C will be on automatically and it will be changed to "Fresh" mode.)
o Set the temperature control at the desired position.
o Set the fan speed control between "1" and "4" position.
To remove the frost or exterior fog on thewindscreen;
o Set the air flow control to the defrost (
)
position. (The A/C will be on automatically and it will be changed to "Fresh" mode.)
o Set the temperature control to the warm.
o Set the fan speed control to position "3" or "4". B720A01FC-EAT DEFROSTING/DEFOGGING
