BRAKE FLUID (IF EQUIPPED)
Checking the brake fluid level
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 fluid, clean the area
around the reservoir cap thoroughly to
prevent brake fluid contamination.
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.
9-30
If the fluid level is excessively low, we
recommend that the system
checked by an authorized Kia dealer.
Use only the specified brake fluid (Re‐
fer to Recommended lubricants or ca‐
pacities on page 10-11.)
Never mix different types of fluid.
WARNING
n Loss of brake fluid
In the event the brake system re‐
quires frequent additions of fluid, we
recommend that the system be in‐
spected by an authorized Kia dealer.
WARNING
n Brake fluid
When changing and adding brake flu‐
id, handle it carefully. Do not let it
come in contact with your eyes. If
brake fluid should come in contact
with your eyes, immediately flush
them with a large quantity of fresh
tap water. Have your eyes examined
by a doctor as soon as possible.
CAUTION
be
Do not allow brake fluid to contact
the vehicle's body paint, as paint
damage will result. Brake 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 system can damage brake
system parts.
