BRAKE FLUID
Checking the brake fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX (Maximum) and MIN
(Minimum) marks on the side of the
reservoir.
Before removing the reservoir cap
and adding brake fluid, clean the
area around the reservoir cap thor-
oughly to prevent brake fluid contam-
ination.If the level is low, add fluid to the
MAX (Maximum) level. The level will
fall with accumulated mileage. This is
a normal condition associated with
the wear of brake linings. If the fluid
level is excessively low, have the
brake system checked by an author-
ized Kia dealer.
Use only the specified brake fluid.
(Refer to “Recommended lubricantsor capacities” in chapter 8.)
Never mix different types of fluid.
In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized Kia dealer.
When changing and adding brake
fluid, 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.
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
disposed of properly.

WASHER FLUID
Checking the washer fluid
level
The reservoir is translucent so that
you can check the level with a quick
visual inspection. Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary. Plain water may be used if
washer fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.

WARNING- Flammable
Fluid
Do not allow the washer fluid to
come in contact with open
flames or sparks. The windshield
washer fluid reservoir is flamma-
ble under certain circumstances.
This can result in a fire.
WARNING- Coolant
Do not use radiator coolant or antifreeze in the washer fluid
reservoir.
Radiator coolant can severely obscure visibility when
sprayed on the windshield
and may cause loss of vehicle
control.
WARNING- Windshield
fluid
Do not drink the windshield
washer fluid. The windshield
washer fluid is poisonous to
humans and animals.

Maintenance
Checking the parking brake
Check whether the stroke is within
specification when the parking brake
pedal is depressed with 30 kg (66 lb,
294 N) of force. Also, the parking
brake alone should securely hold the
vehicle on a fairly steep grade. If the
stroke is more or less than specified,
have the parking brake adjusted by
an authorized Kia dealer.
Stroke : 8~9 notch

air filter, replace it performing the fol-
lowing procedure, and be careful to
avoid damaging other components.
