BRAKE/CLUTCH FLUID (IF EQUIPPED)
Checking the brake/clutch fluid
level
OJF075008
Check the fluid level in the reservoir pe‐
riodically. The fluid level should be be‐
tween 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 contamina‐
tion.
If the level is low, add fluid to the MAX
level. The level will fall with accumula‐
ted 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 Kia dealer.
Use only the specified brake fluid (Re‐
fer to Recommended lubricants and
capacities on page 9-15).
Never mix different types of fluid.
WARNING
n Loss of brake/clutch fluid
In the event the brake/clutch system
requires frequent additions of fluid,
we recommend that the system be
inspected by an authorized Kia deal‐
er.
WARNING
n Brake/clutch fluid
When changing and adding brake/
clutch fluid, handle it carefully. Do
not let it come in contact with your
eyes. If brake/clutch fluid should
come in contact with your eyes, im‐
mediately flush them with a large

quantity of fresh tap water. Have
your eyes examined by a doctor as
soon as possible.
CAUTION
Do not allow brake/clutch fluid to
contact the vehicle's body paint, as
paint damage will result. Brake/
clutch fluid which has been exposed
to open air for an extended time
should never be used as its quality
cannot be guaranteed. It should be
properly disposed. Don't put in the
wrong kind of fluid. A few drops of
mineral-based oil, such as engine oil,
in your brake/ clutch system can
damage brake/clutch system parts.
