CHECKING THE ENGINE OIL
Engine oil is essential to the performance andservice of the engine. It is suggested that youcheck the oil level at least once a week innormal use and more often if you are on a tripor driving in severe conditions. G030B02GK-GAT
Recommended Oil SH, SG or SG/CD (API) multi-grade and fuel efficient oil is recommended.

6-12 While the engine is idling, apply the brakes and move the gear selector lever from "P" to eachof its other positions — "R", "N", "D" — andthen return to "N" or "P". With the engine stillidling:
1. Open the hood, being careful to keep hands, long hair and clothing clear of any movingparts.
2. Remove the transaxle dipstick, wipe it clean, reinsert the dipstick as far as it will go, thenremove it again. Now check the fluid level onthe dipstick. It should be in the "HOT" rangeon the dipstick.
3. If the transaxle fluid level is low, use a funnel to add transaxle fluid through the dipsticktube until the level reaches the "HOT" range.Do not overfill. 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 cooling 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.Fluid level should be within this range

To Check the Transaxle Fluid Level

Park the car on level ground with the parking
brake engaged. When the transaxle fluid level is checked, the transaxle fluid should be atnormal operating temperature and the engineidling.

Transaxle Fluid Capacity
The fluid capacity of the automatic transaxle is
7.8 liters (8.2 U.S. quarts).
WARNING: The transaxle fluid level should be checked
when the engine is at normal operating tem- perature. This means that the engine, radia-tor, exhaust system etc., are very hot. Exer-cise great care not to burn yourself duringthis procedure.

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.

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.

4. Replace the air filter with a new one.
5. Installation is the reverse order of disassem-
bly.
CAUTION: Be sure to install the air filter in the directionof the arrow sign. Otherwise, it may causenoise or deterioration.

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.

A090A01A-AATResponsibilty For Maintenance
It is the responsibility of the vehicle owner/driver to ensure that all routine maintenance services are undertaken in line with the recommendations specifiedin Section 5 of this manual. In addition, in order to ensure continued validity of the new vehicle warranty and safe operation of the vehicle, non scheduled mainte- nance/running repairs should be undertaken at the earliest available opportunity.Under severe operating conditions, more frequent maintenance is required. Details of the maintenance schedule for such conditions are also given in section 5.It is recommended that all maintenance operations and repairs are entrusted to a franchised Hyundai dealer to ensure that the latest repair methods, specialized tooling and genuine Hyundai parts are used to ensure the continued reliability andsafety of the vehicle.
