PARKING BRAKE
Checking the parking brake
Type A
Check whether the stroke is within
specification when the parking brake
pedal is depressed with 20 kg (44 lb,
196N) 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,
we recommend that the system be
serviced by an authorized HYUNDAI
dealer.
Stroke : 3 notch
Type B
Check the stroke of the parking
brake by counting the number of
“clicks’’ heard while fully applying it
from the released position. Also, the
parking brake alone should securely
hold the vehicle on a fairly steep
grade. If the stroke is more or less
than specified, we recommend that
the system be serviced by an author-
ized HYUNDAI dealer.
Stroke : 5~6 “clicks’’ at a force of
20 kg (44 lbs, 196 N).

CLIMATE CONTROL AIR FILTER
Filter inspection

Maintenance
Do not allow the wiper arm to fall
against the windshield, since it
may chip or crack the windshield.
CAUTION
WIPER BLADES
Blade inspection
Information
Commercial hot waxes applied by
automatic car washes have been
known to make the windshield dif-
ficult to clean.
Contamination of either the wind-
shield or the wiper blades with for-
eign matter can reduce the effective-
ness of the windshield wipers.
Common sources of contamination
are insects, tree sap, and hot wax
treatments used by some commer-
cial car washes. If the blades are not
wiping properly, clean both the win-
dow and the blades with a good
cleaner or mild detergent, and rinse
thoroughly with clean water.
To prevent damage to the wiper
blades, do not use gasoline,
kerosene, paint thinner, or other
solvents on or near them.
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.

BATTERY
For best battery service
•Keep the battery securely mounted.
•Keep the battery top clean and dry.
•Keep the terminals and connec-
tions clean, 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, discon-
nect the battery cables.
Information
Basically equipped battery is
maintenance free type. If your
vehicle is equipped with the bat-
tery marked with LOWER and
UPPER on the side, you can check
the electrolyte level. The elec-
trolyte level should be between
LOWER and UPPER. If the elec-
trolyte level is low, it needs to add
distilled (demineralized) water
(Never add sulfuric acid or other
electrolyte). When refill, be careful
not to splash the battery and adja-
cent components. And do not
overfill the battery cells. It can
cause corrosion on other parts.
After then ensure that tighten the
cell caps. We recommend that you
contact an authorized HYUNDAI
dealer.
i
Battery dangers
Always read the follow-
ing instructions carefully
when handling a battery.
Keep lighted cigarettes
and all other flames or
sparks away from the
battery.
Hydrogen, a highly com-
bustible gas, is always
present in battery cells
and may explode if ignit-
ed.
Keep batteries out of the
reach of children because
batteries contain highly
corrosive SULFURIC
ACID. Do not allow bat-
tery acid to contact your
skin, eyes, clothing or
paint finish.

Maintenance
(Continued)
If any electrolyte gets
into your eyes, flush
your eyes with clean
water for at least 15 min-
utes and get immediate
medical attention. If elec-
trolyte gets on your skin,
thoroughly wash the
contacted area. If you
feel a pain or a burning
sensation, get medical
attention immediately.
Wear eye protection
when charging or work-
ing near a battery.
Always provide ventila-
tion when working in an
enclosed space.
An inappropriately dis-
posed battery can be
harmful to the environ-
ment and human health.
Dispose the battery
according to your local
law(s) or regulation.
(Continued)
(Continued)
•When lifting a plastic-cased
battery, excessive pressure
on the case may cause battery
acid to leak, resulting in per-
sonal injury. Lift with a battery
carrier or with your hands on
opposite corners.
•Never attempt to recharge the
battery when the battery
cables are connected.
•The electrical ignition system
works with high voltage.
Never touch these compo-
nents with the engine running
or the ignition switch is in the
on position.
Failure to follow the above
warnings can result in serious
bodily injury or death.
If you connect unauthorized
electronic devices to the bat-
tery, the battery may be dis-
charged. Never use unautho-
rized devices.
