If the level is low, add fluid to the MAX level. The level will fall with accumulated mileage.

If the fluid level is excessively low, have the brake/clutch* system checked by an authorized Kia dealer.

Use only the specified brake/clutch* fluid. (Refer to “Recommended lubricants and capacities” in section 8.)
