POWER STEERING FLUID
Checking the power steering fluid
level
With the vehicle on level ground, check
the fluid level in the power steering reser-
voir periodically. The fluid should be
between MAX and MIN marks on the
side of the gauge at the normal tempera-
ture. Before adding power steering fluid, thor-oughly clean the area around the reser-
voir cap to prevent power steering fluidcontamination.
If the level is low, add fluid to the MAX
level.
In the event the power steering system requires frequent addition of fluid, the
vehicle should be inspected by an
authorized HYUNDAI dealer.
Use only the specified power steering
fluid. (Refer to "Recommended lubricants
or capacities" in section 8.)
Checking the power steering hose
Check the connections for oil leaks, dam-
age and twists in the power steering
hose before driving.
CAUTION
To avoid damage to the power steering water pump unit, do not
operate the vehicle for prolonged periods with a low power steeringfluid level.
Never start the engine when the reservoir tank is empty.
When adding fluid, be careful that dirt does not get into the tank.
Too little fluid can result in increased steering effort and/ornoise from the power steering
system.
The use of the non-specified fluid could reduce the effectiveness ofthe power steering system andcause damage to it.

Checking the washer fluid level
The reservoir is translucent so that you
can check the level with a quick visualinspection.
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.
WASHER FLUID
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 or damage
to paint and body trim.
Windshield Washer fluid agents contain some amounts of alcohol
and can be flammable under cer-
tain circumstances. Do not allowsparks or flame to contact thewasher fluid or the washer fluid
reservoir. Damage to the vehicle
or occupants could occur.
Windshield washer fluid is poi- sonous to humans and animals.
Do not drink and avoid contacting
windshield washer fluid. Serious
injury or death could occur.

Filter inspection The climate control air filter should be replaced according to the Maintenance
Schedule. If the vehicle is operated in
severely air-polluted cities or on dusty
rough roads for a long period, it shouldbe inspected more frequently and
replaced earlier. When you replace the
climate control air filter, replace it per-
forming the following procedure, and be
careful to avoid damaging other compo-
nents.

filter, install it properly. Otherwise, the
system may produce noise and the effec-

Blade inspection
✽✽ NOTICE
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.
OBH078017 WIPER BLADESCAUTION
To prevent damage to the wiper
blades, do not use gasoline,kerosene, paint thinner, or other
solvents on or near them.
