Brake Fluid/Clutch Fluid
Brake Fluid/Clutch Fluid Level Inspection

Check the fluid level in the reservoir periodically. The fluid level should be between the MAX and MIN marks on the side of the reservoir.
Before removing the reservoir cap and adding brake/clutch fluid, thoroughly clean the area around the reservoir cap to prevent contamination of the brake/clutch fluid.
If the level is low, add the specified brake/clutch fluid to the MAX level. The level will drop as mileage accumulates. This is normal and is related to brake/clutch pad wear. If the fluid level is too low, have the brake/clutch system checked by an authorized HYUNDAI dealer.
WARNING
If the brake system requires frequent fluid additions, this may indicate a leak in the brake system. Have the vehicle inspected at an authorized HYUNDAI dealer.
WARNING
Do not allow brake/clutch fluid to get into your eyes. If brake/clutch fluid gets into your eyes, flush your eyes with clean water for at least 15 minutes and seek medical attention immediately.
NOTICE
- Do not allow brake/clutch fluid to contact the vehicle body paint, as this will damage the paint.
- Brake/clutch fluid that has been exposed to air for a long time should NEVER be used, as its quality cannot be guaranteed. It must be disposed of properly.
- Do not use the wrong type of brake/clutch fluid. Even a few drops of mineral oil-based oil, such as engine oil, in the brake/clutch system can damage brake/clutch system components.
Information
Use only the specified brake/clutch fluid (see "Recommended Lubricants" section and capacities in Chapter 8).
