Maintenance BRAKE/CLUTCH FLUID Changing the coolant WARNING The cooling fan is controlled by engine coolant temperature and may sometimes operate even when the engine is not running. Use extreme caution when working near the blades of the coolant fan so that you are not injured by a rotating fan blade. As the engine coolant temperature decreases, the fan will automatically shut off. This is a normal condition. Have coolant changed by an authorized HYUNDAI dealer according to the Maintenance Schedule at the beginning of this section. CAUTION Put a thick cloth or fabric around the radiator cap before refilling the coolant in order to prevent the coolant from overflowing into engine parts such as generator. OYF079007N WARNING - Coolant • Do not use radiator coolant or antifreeze in the washer fluid reservoir. • Radiator coolant can severely obscure visibility when sprayed on the windshield and may cause loss of vehicle control or damage to paint and body trim. Checking the brake/clutch fluid level Check the fluid level in the reservoir periodically. The fluid level should be between MAX and MIN marks on the side of the reservoir. Before removing the reservoir cap and adding brake/clutch fluid, clean the area around the reservoir cap thoroughly to prevent brake/clutch fluid contamination. If the level is low, add fluid to the MAX level. The level will fall with accumulated mileage. This is a normal condition associated with the wear of the brake linings. If the fluid level is excessively low, have the brake system or clutch (if equipped) checked by an authorized HYUNDAI dealer. 7 26
