BRAKE FLUID
Checking the brake fluid level
Check the fluid level in the reservoir peri-
odically. The fluid level should be
between 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 accumulated
mileage. This is a normal condition asso-
ciated with the wear of the brake linings
and/or clutch disc (if equipped). If the
fluid level is excessively low, have the
brake system checked by an authorized
Kia dealer.
Use only the specified brake fluid. (Refer
to “Recommended lubricants and capac-ities” in section 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.
CAUTION - Brake fluid
Do not allow brake fluid to contact
the vehicle's body paint, as paintdamage will result.
CAUTION - Proper fluid
Only use brake fluid in brake sys- tem. Small amounts of improper flu-ids (such as engine oil) can causedamage to the brake system.

Maintenance
Checking the washer fluid level
Check the fluid level in the washer fluid
reservoir and add fluid if necessary. 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.
Checking the parking brake
Check whether the stroke is within spec-
ification when the parking brake pedal is
depressed with 20 kg (44 lb, 196 N) of
force. Also, the parking brake alone
should securely hold the vehicle on a fair-
ly steep grade.
WARNING - Windshield
fluid
Do not drink the windshield washer
fluid. The windshield washer fluid is
poisonous to humans and animals.
WARNING - Flammable
fluid
Do not allow the washer fluid to
come in contact with open flames
or sparks. The windshield washer
fluid clan is flammable under cer-
tain circumstances. This can result
in a fire.

WIPER BLADES
Blade inspection
Commercial hot waxes applied by auto-
matic car washes have been known to
make the windshield difficult to clean.
Contamination of either the windshield or
the wiper blades with foreign matter can
reduce the effectiveness of the wind-
shield wipers. Common sources of con-
tamination are insects, tree sap, and hot
wax treatments used by some commer-
cial car washes. If the blades are not wip-
ing properly, clean both the window and
the blades with a good cleaner or mild
detergent, and rinse thoroughly with
clean water.
Blade replacement
When the wipers no longer clean ade-
quately, the blades may be worn or
cracked, and require replacement.
To prevent damage to the wiper arms or
other components, do not attempt to
move the wipers manually.
The use of a non-specified wiper blade
could result in wiper malfunction and fail-
ure.

1. Raise the wiper arm and turn the wiper
blade assembly to expose the plastic

BATTERY
For best battery service
Keep the battery securely mounted.
Keep the battery top clean and dry.
Keep the terminals and connectionsclean, tight, and coated with petroleum
jelly or terminal grease.
Rinse any spilled electrolyte from the battery immediately with a solution of
water and baking soda.
If the vehicle is not going to be used for an extended time, disconnect the bat-
tery cables.
WARNING - Risk of
explosion
Keep Lit cigarettes and all
other flames or sparks
away from the battery.
The battery contains hydro-
gen -- a highly combustible
gas, which will explode if it
comes in contact with a
flame or spark.
WARNING - Sulfuric acid
in batteries
Keep batteries out of the
reach of children because
batteries contain highly
corrosive SULFURIC ACID
and electrolytes. Do not
allow battery acid to con-
tact your skin, eyes, cloth-
ing or paint finish.
Wear eye protection when charging or working near a
battery. Always provide
ventilation when working in
an enclosed space.
