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,

we recommend that the system be checked by an authorized HYUNDAI dealer.

If the brake/clutch system requires frequent additions of fluid this could indicate a leak in the brake/clutch system. We recommend that the vehicle be inspected by an authorized HYUNDAI dealer.

Do not let brake/clutch fluid enter into your eyes. If brake/clutch fluid gets in your eyes, flush your eyes with clean water for at least 15 minutes and get immediate medical attention.

  • Do not allow brake/clutch fluid to contact the vehicle's body paint, as it will result in paint damage.

  • NEVER use brake/clutch fluid which has been exposed to open air for an extended time, as its quality cannot be guaranteed. It should be disposed of properly.

  • Don't put in the wrong type of fluid. A few drops of mineral-based oil, such as engine oil in your brake/clutch system can damage system parts.

Use only the specified brake/clutch fluid. Refer to "Recommended lubricants and capacities" in chapter 2.

Before removing the brake/clutch filler cap, read the warning on the cap.

Clean the filler cap before removing. Use only DOT4 brake/clutch fluid from a sealed container.
