AIR CONDITIONING CARE
G140A01A-AAT Keeping the Condenser Clean The air conditioning condenser (and engine radiator) should be checkedperiodically for accumulation of dirt, dead insects, leaves, etc. These can interfere with maximum cooling effi-ciency. When removing such accumu- lations, brush or hose them away care- fully to avoid bending the cooling fans. 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 condi-tioning system inspected by yourHyundai dealer.
G140C01A-AAT Lubrication To lubricate the compressor and the seals in the system, the air conditioning should be run for at least 10 minuteseach week. This is particularly important during cool weather when the air condi- tioning system is not otherwise in use.
! CAUTION:
Running the air conditioning sys- tem for extended periods of time with a low refrigerant level may damage the compressor.
G130B02A-AAT To Replace the Fluid Recommended brake fluid conforming to DOT 3 or DOT 4 specification shouldbe used. The reservoir cap must be fully tightened to avoid contamination from foreign matter or moisture. NOTE: Do not allow any other liquids to contaminate the brake fluid. Sealdamage will result.
WARNING:
Use caution when handling brake fluid. It can damage your vision if you get it in your eyes. It will alsodamage your vehicles paint if spilled on it and not removed immediately.

You need a helper to check the brake pedal clearance. With the engine run- ning, have your helper press down on the brake pedal several times and thenhold it down with a force of about 490 N (50 Kg, 110 lbs). The brake pedal clearance is the distance from the topsurface of the brake pedal to the as- phalt sheeting under the floor mat. If the brake pedal clearance is notwithin the limits specified in the illustra- tion, have it inspected by your Hyundai dealer and adjusted or repaired if nec-essary. HTB186

3 ~ 8 mm (0.12 ~ 0.31 in.)
With the engine off, press down on the brake pedal several times to reduce the vacuum in the brake booster.Then, using your hand, press down slowly on the brake pedal until you feel a change in resistance. This is thebrake pedal freeplay. The freeplay should be within the limits specified in the illustration. If it is not,have it inspected by your Hyundai dealer and adjusted or repaired if nec- essary. Drive belts should be checked periodi- cally for proper tension and adjusted if necessary. At the same time, beltsshould be examined for cracks, wear, fraying or other evidence of deteriora- tion and replaced if necessary.Belt routing should also be checked to be sure there is no interference be- tween the belts and other parts of theengine. After a belt is replaced, the new belt should be adjusted again after two or three weeks to eliminateslack resulting from initial stretching after use.

28CHECKING AND REPLACING FUSES
CAUTION:
When replacing a fusible link, never use anything but a new fusible link with the same or lower amperagerating. Never use a piece of wire or a higher-rated fusible link. This could result in serious damage andcreate a fire hazard.!

At the scheduled maintenance inspec- tion, belts should be examined for cracks, wear, fraying or other evidenceof deterioration and replaced if neces- sary. Belt routing should also be checked tobe sure there is no interference be- tween the belts and other parts of the engine. A fusible link will melt if the electricalcircuits from the battery are ever over- loaded, thus preventing damage to the entire wiring harness. (This could becaused by a short in the system draw- ing too much current.) If this ever happens, have a Hyundai dealer de-termine the cause, repair the system and replace the fusible link. The fusible links are located in a fuse box for easyinspection.

G210B01A-AAT Checking the Battery Keep the battery clean. Any evidence of corrosion around the battery postsor terminals should be removed using a solution of household baking soda and warm water. After the battery ter-minals are dry, cover them with a light coating of grease.
Keep batteries out of the reach of children because batteries contain highly cor- rosive SULFURIC ACID. Donot allow battery acid to con- tact your skin, eyes, cloth- ing or paint finish.If any electrolyte gets into your eyes, flush your eyes with clean water for at least15 minutes and get immedi- ate medical attention. If pos- sible, continue to applywater with a sponge or cloth until medical attention is re- ceived.If electrolyte gets on your skin, thoroughly wash the contacted area.If you feel a pain or a burn- ing sensation, get medical attention immediately.Wear eye protection when charging or working near a battery.Always provide ventilation when working in an en- closed space.
WARNING: Always read the following instructions carefully when handling a battery.Keep lighted cigarettes and all other flames or sparks away from the battery.Hydrogen, which is a highly combustible gas, is always present in battery cells andmay explode if ignited.!
o When lifting a plastic-cased bat- tery, excessive pressure on the case may cause battery acid to leak, resulting in personal injury. Lift with a battery carrier or withyour 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 components with the engine running or the ignition switched on.

32POWER 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. HLC5006
CHECKING 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 comes on 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.

G300B01A G300A01A
G240A01A-AAT POWER STEERING HOSES It is suggested that you check the power steering hose connections forfluid 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. G300A02B-GAT (DIESEL ENGINE) If the fuel filter warning light illuminates during driving, it indicates that waterhas accumulated in the fuel filter. If this occurs, remove the water as described below.
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.
!WARNING:
Be sure to carefully wipe away any water drained out in this manner, because the fuel mixed in the water might be ignited and result in a fire.
