DO-IT-YOURSELF MAINTENANCE
6-16 G140B01A-AAT 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 LubricationTo 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.

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.
The clutch fluid level in the master cylinder
should be checked when performing other un- der hood services. The system should bechecked for leakage at the same time. Check tomake certain that the clutch fluid level is always

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 en-gine coolant temperature decreases the fanwill automatically shut off. This is a normalcondition.
G220B01A-AAT
Checking Engine Cooling Fan The engine coolant fan should come on auto-
matically if the engine coolant temperature ishigh.
G220C01A-AAT
Checking Condenser Cooling Fan The condenser coolant fan should come on
automatically whenever the air conditioning isin operation. G230A03A-GAT

Checking the Battery Keep the battery clean. Any evidence of corro-
sion around the battery posts or terminals should be 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.
o If you swallow battery fluid, drink a large
quantity of water or milk followed by milk ofmagnesia, eat a raw egg or drink vegetableoil. Get medical assistance as soon aspossible.
While batteries are being charged (either by abattery charger or by the vehicle’s alternator),they produce explosive gases. Always observethese warnings to prevent injuries from occur-ring:
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.
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.

The fuel gauge indicates the quantity of fuel remaining in the fuel tank. NOTE: The fuel gauge is not intended to giveother than an approximate indication ofthe fuel level and is unsuitable for thepurposes of calculating fuel consumptionfigures. SB215B1-E
ENGINE COOLANT TEMPERATURE GAUGE
The engine coolant temperature gauge indi-
cates the engine coolant temperature and will, under normal circumstances, give an indica-tion in the "Normal" or centre portion of thescale. Should the indication move into theupper or "Hot" portion of the scale, engineoverheating is indicated. Under these circum-stances, the vehicle should be brought to restas soon as is safe to do so and the engineturned off. Once the engine has cooled some-what, the coolant level and the condition ofthe generator/water pump drive belt should bechecked. If the cause of the overheating can-not be readily established, the assistance of aHyundai dealer should be sought.

WARNING: The engine cooling system is pressurized
and removal of the radiator cap when the engine is hot may cause hot water andsteam to be ejected from the radiator re-sulting in burns and scalding. The radiatorcap must only be removed when the en-gine has cooled. Do not add cold water toa hot engine to avoid the possibility ofengine damage. The use of plain water inthe cooling system is not recommendedsince the aluminium components of thecooling system require the use of a corro-sion inhibitor found in the recommendedEthylene Glycol type anti freeze solutions.

o Air for the heating/cooling system is drawn in through the grilles just ahead of thewindscreen. Care should be taken thatthese are not blocked by leaves, snow, iceor other obstructions.
o To prevent interior fog on the windscreen, set the air intake control to the fresh air(
) position and fan speed to the desired
position.
NOTE: When the A/C is operated continuously on the floor-defrost level (
) or defrost level
(), it may cause fog to form on the exte-
rior windscreen. If this occurs, set the air flow control to the face level position (

o Set the air flow control to the desired position.
o Adjust the fan control to the desired speed.
o For more rapid action, set the fan at one of the higher speeds.
o Adjust the temperature control to provide the desired amount of warmth. B740D01A-AAT Operation Tips
o If the interior of the car is hot when you first
get in, open the windows for a few minutes to expel the hot air.
o When you are using the air conditioning system, keep all windows closed to keephot air out.
o When moving slowly, as in heavy traffic, shift to a lower gear. This increases enginespeed, which in turn increases the speedof the air conditioning compressor.
o On steep grades, turn the air conditioning off to avoid the possibility of the engineover-heating.
o During winter months or in periods when the air conditioning is not used regularly,run the air conditioning once every monthfor a few minutes. This will help circulatethe lubricants and keep your system inpeak operating condition.
