Fluid level should be within "HOT" range
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 the blades of the cooling fan, so that you are not injured by a rotating fan blade. As the en- gine coolant temperature decreases, the fan will automatically shut off. This is a normal condition. WARNING (Diesel only): Never work on injection system with enginerunning or within 30 seconds after shutting off engine. High pressure pump, rail, injec- tors and high pressure pipes are subjected to high pressure even after the engine has been switched off. The fuel jet produced by fuel leaks may cause serious injury, if it contacts with the body. People using pace- makers should not move closer than 30cm to the ECU or wiring harness within the
Park the car on level ground with the parking brake engaged. When the transmission fluid level is checked, the transmission fluid should be at normal operating temperature and the engine idling.
While the engine is idling, apply the brakes and move the gear selector lever from "P" to each of its other positions — "R", "N", "D", "2", "L" — and then return to "N" or "P". With the engine still idling:
1. Open the hood, being careful to keep hands,
long hair and clothing clear of any moving parts.
2. Remove the transmission dipstick, wipe it clean, reinsert the dipstick as far as it will go,then remove it again. Now check the fluid level on the dipstick. It should be in the "HOT" range on the dipstick.
3. If the transmission fluid level is low, use a funnel to add transmission fluid through thedipstick tube until the level reaches the "HOT" range. Do not overfill.

G130A01HP
The clutch fluid level in the master cylinder should be checked when performing other un- der hood services. The system should be checked for leakage at the same time. Check to make certain that the clutch fluid level is always between the "MAX" and "MIN" level markings on the fluid reservoir. Fill as required. Fluid loss indicates a leak in the clutch system which should be inspected and repaired immediately. Consult your Hyundai dealer.
G120E02A-AAT Adding Brake Fluid
WARNING: Handle brake fluid carefully. It can damage your vision if it gets into your eyes. Use only DOT 3 or DOT 4 specification fluid from a sealed container. Do not allow the fluid can or reservoir to remain open any longer than required. This will prevent entry of dirt and moisture which can damage the brake sys- tem and cause improper operation.
G120E01HP
G120D01A-AAT To Check the Fluid LevelThe fluid level in the brake fluid reservoir should be checked periodically. The level should be between the "MIN" and "MAX" marks on the side of the reservoir. If the level is at or below the "MIN" mark, carefully add fluid to bring it up to "MAX". Do not overfill.
To add brake fluid, first wipe away any dirt then
unscrew the fluid reservoir cap. Slowly pour therecommended fluid into the reservoir. Do not overfill. Carefully replace the cap on the reser- voir and tighten.
G120A01A-AAT CHECKING THE BRAKESCAUTION: Because brakes are essential to the safe operation of the car, it is suggested that they be checked and inspected by your Hyundai dealer. The brakes should be checked and inspected for wear at those intervals specified in the vehicle mainte- nance schedule in Section 5. G120B02A-AAT Checking the Brake Fluid Level WARNING: Use caution when handling brake fluid. It can damage your vision if it gets into your eyes. It will also damage your vehicle’s paint if 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 avoid bending the cooling fans.
G130B02A-AAT To Replace the FluidRecommended brake fluid conforming to DOT 3 or DOT 4 specification should be used. The reservoir cap must be fully tightened to avoid contamination 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. Itcan damage your vision if you get it in your eyes. It will also damage your vehicle’s paint if spilled on it and not removed immediately.
When the air conditioning is being used regular-
ly, the compressor drive belt tension should be checked at least once a month. To check the drive belt tension, press down on

3. Be sure to check all other fuses even if you find one that appears to have burned out.
4. Replace the blown fuse by pressing a new
fuse of the same rating into place. The fuse should be a snug fit. If it is not, have the fuse clip repaired or replaced by a Hyundai dealer. If you do not have a spare fuse, you may be able to borrow a fuse of the same or lower rating from an accessory you can tempo- rarily get along without (the radio or cigarette lighter, for example). Always remember to replace the borrowed fuse.
1. Turn off the ignition and all other switches.
2. Open the fuse box and examine each fuse.
Remove each fuse by pulling it toward you (a small "fuse puller" tool is contained in the relay box to simplify this operation).

G200B03YBurned out
CAUTION: A burned-out fuse indicates that there is a
problem in the electrical circuit. If you re-place a fuse and it blows as soon as the accessory is turned on, the problem is seri- ous and should be referred to a Hyundai dealer for diagnosis and repair. Never re- place a fuse with anything except a fuse with the same or a lower amperage rating. A higher capacity fuse could cause damage and create a fire hazard.

G200B01HP
The fuse box for the lights and other electrical accessories will be found under the dashboard on the driver’s side. Inside the box you will find a list showing the circuits protected by each fuse.If any of your car’s lights or other electrical accessories stop working, a blown fuse could be the reason. If the fuse has burned out, you will see that the metal strip inside the fuse has burned through. If you suspect a blown fuse, follow this procedure:
CAUTION: When replacing a fusible link, never useanything but a new fusible link with the same or lower amperage rating. Never use a piece of wire or a higher-rated fusible link. This could result in serious damage and create a fire hazard.

G210A01A-AAT CHECKING THE BATTERYWARNING: Batteries can be dangerous! When working with batteries, carefully observe the follow- ing precautions to avoid serious injuries. The fluid in the battery contains a strong solu- tion of sulfuric acid, which is poisonous and highly corrosive. Be careful not to spill it on yourself or the car. If you do spill battery fluid on yourself, immediately do the following:
o If battery fluid is on your skin, flush the
affected areas with water for at least 15 minutes and then seek medical assistance.
o If battery fluid is in your eyes, rinse out your eyes with water and get medical assistanceas soon as possible. While you are being driven to get 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 followed by milk ofmagnesia, eat a raw egg or drink vegetable oil. Get medical assistance as soon as possible.
While batteries are being charged (either by a battery charger or by the vehicle’s alternator), they produce explosive gases. Always observe these warnings to prevent injuries from occur- ring:
