o If battery fluid is on your skin, flush
the affected areas with water for at least 15 minutes and then seek medi- cal assistance.
o If battery fluid is in your eyes, rinse out your eyes with water and getmedical assistance as soon as pos- sible. While you are being driven toget medical assistance, continue to rinse your eyes by using a sponge or soft cloth saturated with water.
o If you swallow battery fluid, drink a large quantity of water or milk fol-lowed by milk of magnesia, eat a rawegg or drink vegetable oil. Get medi- cal assistance as soon as possible.
While batteries are being charged (ei-ther by a battery charger or by the vehicle's alternator), they produce ex-plosive gases. Always observe these warnings to prevent injuries from oc- curring:
o Charge batteries only in a well ven- tilated area.
o Do not permit flames, sparks or smoking in the area.
o Keep children away from the area.G210B01HR-GET Checking the Battery Keep the battery clean. Any evidence of corrosion around the battery posts orterminals should be removed using a solution of household baking soda and warm water. After the battery terminalsare dry, cover them with a light coating of grease.
WARNING:Always read the following instructions carefully when handling a battery. Keep lighted cigarettes andall other flames or sparks away from the battery. Hydrogen, which is a highlycombustible gas, is always present in battery cells and may explode if ignited.Keep batteries out of the reach of children because batteries contain highly cor-rosive SULFURIC ACID. Do not allow battery acid to con- tact your skin, eyes, cloth-ing or paint finish. If any electrolyte gets intoyour eyes, flush your eyes with clean water for at least 15 minutes and get immedi-ate medical attention. If pos- sible, continue to apply water with a sponge or clothuntil medical attention is re- ceived. If electrolyte gets on yourskin, thoroughly wash the contacted area. If you feel a pain or a burn-ing sensation, get medical attention immediately. Wear eye protection whencharging or working near a battery.

26POWER STEERING FLUID LEVEL
G230A03A-GAT The power steering fluid level should be checked regularly. To check the power steering fluid level, be sure the ignition is "OFF", thencheck to make certain that the power steering fluid level is between the "MAX" and "MIN" level markings on the fluidreservoir. NOTE: Grinding noise from the power steer- ing pump may be heard immediatelyafter the engine is started in extremely cold conditions (below - 20°C). If the noise stops during warm up, there isno abnormal function in the system. HHR5014CHECKING ELECTRIC COOLING FANS
!
G220B01A-AAT Checking Engine Cooling Fan The engine cooling fan should come on automatically if the engine coolant tem- perature is high. G220C01TB-GAT Checking Condenser Cooling Fan When the air conditioning is in opera- tion, the condenser cooling fan comeson automatically to be controlled by ECU.
G220A01A-AAT
WARNING:
The cooling fan is controlled by en- gine coolant temperature and may sometimes operate even when the engine is not running. Use extremecaution when working near the blades of the cooling fan, so that you are not injured by a rotating fanblade. As the engine coolant temper- ature decreases the fan will automat- ically shut off. This is a normal con-dition.
o When lifting a plastic-cased bat- tery, excessive pressure on the case may cause battery acid toleak, resulting in personal injury. Lift with a battery carrier or with your hands on opposite corners.
o Never attempt to charge the bat- tery when the battery cables areconnected.
o The electrical ignition system works with high voltage.Never touch these componentswith the engine running or the ignition switched on.

G350B01HR-GAT BLEEDING THE FUEL SYSTEM
The fuel system should be bled to remove air as described in the illustra-tion if the fuel supply is exhausted during travel, when the fuel filter is replaced, or if the vehicle is not used fora long time.
1. Loosen the air plug at the upper part of the fuel filter.
NOTE: The fuel filter is located under the driver's seat. To bleed the fuel sys- tem, first tilt the driver's seatback forward. (Refer to "To Inspect theEngine Compartment Under the Driver's Seat." on page 1-12.) HHR4046
2. Pump the hand pump until there are
no more bubbles in the fuel coming out of the air plug. When doing this,place a cloth around the air plug to prevent the escaping fuel from spew- ing about.
3. Tighten the air plug when there are no more bubbles in the fuel.
4. Continue pumping until the hand
pump becomes stiff.
5. Finally, check to be sure that there is
no leakage of fuel.If in doubt, consult your nearest au- thorized HYUNDAI dealer. HHR4047
FUEL FILTER
G240A01A-AAT POWER STEERING HOSES It is suggested that you check the power steering hose connections for fluid leakage at regular intervals. The power steering hoses should be re-placed if there is severe surface crack- ing, scuffing or worn spots. Deteriora- tion of the hose could cause prema-ture failure.
It is due to a power steering fluidcharacteristic in extremely cold con-ditions. Recommended Fluid Use PSF-3 type fluid NOTE: Do not start the engine when the power steering oil reservoir is empty.

30REPLACEMENT OF LIGHT BULBS
If the vehicle has had front body repair and the headlight assembly has been replaced, an headlight aiming should be checked using an aiming screen asshown in the illustration. Turn on the headlight switch. (Low Beam Position)
1. Adjust headlights so that main axis of light is parallel to center line of the body and is aligned with point "P"shown in the illustration.
2. Dotted lines in the illustration show
the center of headlights. SPECIFICATIONS: "H" Horizontal center line of headlights from ground.Low Deck: 815 mm (32.1 in.) High Deck: 820 mm (32.3 in.) "W" Distance between each headlight center : 1,330 mm (52.4 in.) "L" Distance between the headlightsand the wall that the lights are tested against. : 3,000 mm (118 in.). G260A03A-AAT Before attempting to replace a light bulb, be sure the switch is turned to the "OFF" position. The next paragraph shows how to reachthe light bulbs so they may be changed. Be sure to replace the burned-out bulb with one of the same number and watt-age rating. See page 6-37 for the wattage descrip- tions.
CAUTION:
o Keep the lamps out of contact with petroleum products, such as oil,gasoline, etc.
o After heavy, driving rain or wash- ing, headlight and taillight lensescould appear frosty. This condi-tion is caused by the temperature difference between the lamp in- side and outside. This is similar tothe condensation on your win- dows inside your vehicle during the rain and doesn’t indicate aproblem with your vehicle. If the water leaks into the lamp bulb circuitry, have the vehicle checkedby an Authorized Hyundai Dealer.
