Checking the brake/clutch fluid
level
OBC3090016R
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the left
or right 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 a HYUNDAI authorised
repairer.
