Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. Particular attention
should be paid to examine those hose
surfaces nearest to high heat sources,
such as the exhaust manifold.
Inspect the hose routing to assure that
the hoses do not come in contact with
any heat source, sharp edges or moving
component which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.
G050800AFD
Air cleaner filter
A Genuine HYUNDAI air cleaner filter is
recommended when the filter is replaced.
G050900AUN
Spark plugs
Make sure to install new spark plugs of
the correct heat range.
G051000AFD
Valve clearance
Inspect excessive valve noise and/or
engine vibration and adjust if necessary.
An authorized HYUNDAI dealer should
perform the operation.
G051100AUN
Cooling system
Check the cooling system parts, such as
radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
G051200AUN
Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
G051300AUN
Manual transaxle fluid
(if equipped)
Inspect the manual transaxle fluid
according to the maintenance schedule.
G051400AXM
Automatic transaxle fluid
(if equipped)
Automatic transaxle fluid should not be
checked under normal usage conditions.
But in severe conditions, the fluid should
be changed at an authorized HYUNDAI
dealer in accordance to the scheduled
maintenance at the beginning of this
chapter.
✽ ✽
NOTICE
Automatic transaxle fluid color is basi-
cally red.
As the vehicle is driven, the automatic
transaxle fluid will begin to look darker.
It is normal condition and you should
not judge the need to replace the fluid
based upon the changed color.

Maintenance
PARKING BRAKE
Checking the parking brake
Type A
Check whether the stroke is within spec-
ification when the parking brake pedal is
depressed with 66 lb (30 kg, 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 HYUNDAI dealer.
Stroke : 8~9 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 fair-
ly steep grade. If the stroke is more or
less than specified, have the parking
brake adjusted by an authorized
HYUNDAI dealer.
Stroke :5~6 “clicks’’ at a force of
44 lbs (20 kg, 196 N).

G190100BUN
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.

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 ignited.
Keep batteries out of the reach of children because
batteries contain highly
corrosive SULFURIC ACID.
Do not allow battery acid to
contact your skin, eyes,
clothing or paint finish.
(Continued)

(Continued)If any electrolyte gets intoyour eyes, flush your eyes
with clean water for at least
15 minutes and get immedi-
ate medical attention.
If electrolyte gets on your
skin, thoroughly wash the
contacted area. If you feel a
pain or a burning sensa-
tion, get medical attention
immediately.
Wear eye protection when charging or working near a
battery. Always provide
ventilation when working in
an enclosed space.
An inappropriately disposed battery can be harmful to
the environment and human
health. Dispose the battery
according to your local
law(s) or regulation.
