Checking the Parking Brake
Check whether the stroke is within
specification when the parking brake
pedal is depressed with 44 lb (20 kg,
196 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 HYUNDAI dealer.
Stroke : 4~5 notch
Filter Replacement
The air cleaner filter can be cleaned
for inspection using compressed air.
Do not attempt to wash or to rinse it,
as water will damage the filter.
If soiled, the air cleaner filter must be
replaced. 1. Loosen the air cleaner cover
attaching clips and open the
cover.

more frequently and replaced earlier.
When you replace the climate control
air filter, replace it performing the fol-
lowing procedure, and be careful to
avoid damaging other components.

Blade Inspection
Contamination of either the wind-
shield or the wiper blades with for-
eign matter can reduce the effective-
ness of the windshield wiper func-
tionality. Common sources of con-
tamination are insects, tree sap, and
hot wax treatments used by some
commercial car washes. If the blades
are not wiping properly, clean both
the window and the blades with a
clean cloth dampened with washer
fluid. To prevent damage to the wiper
blades, arms or other compo-
nents, do not:
Use gasoline, kerosene, paint
thinner, or other solvents on or
near them.
Attempt to move the wipers manually.
Use non-specified wiper blades.
Information
Commercial hot waxes applied by
automatic car washes have been
known to make the windshield diffi-
cult to clean.
Blade Replacement
When the wipers no longer clean
adequately, 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 manu-
ally.
The use of a non-specified wiper
blade could result in wiper mal-
function and failure.

wash the area. If you feel pain or
a burning sensation, get med-
ical attention immediately.
