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 the specified brake/clutch fluid to the MAX level. The level will fall with accumulated mileage. This is a normal condition associated with the wear of the brake/clutch linings. If the fluid level is excessively low, have the brake/ clutch system checked by an authorized HYUNDAI dealer.
WARNING
If the brake system requires frequent additions of fluid this could indicate a leak in the brake system. Have the vehicle inspected by an authorized HYUNDAI dealer.
WARNING
Do not allow brake/clutch fluid to come in contact with your eyes. If brake/clutch fluid comes in contact with your eyes, flush your eyes with clean water for at least 15 minutes and get immediate medical attention.
NOTICE
Information
Use only the specified brake/clutch fluid (refer to "Recommended Lubricants and Capacities" in chapter 8).
