Maintenance
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler cap iscorrectly replaced.
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 movingcomponent 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.Air cleaner filter
A Genuine HYUNDAI air cleaner filter is recommended when the filter isreplaced. Spark plugs
Make sure to install new spark plugs of
the correct heat range.
Valve clearance (3.8L)
Inspect excessive valve noise and/or
engine vibration and adjust if necessary.
An authorized HYUNDAI dealer should
perform the operation. Cooling system
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Coolant The coolant should be changed at the
intervals specified in the maintenance
schedule. Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately. Brake fluid
Check brake fluid level in the brake fluid
reservoir. The level should be between
“MIN” and “MAX” marks on the side of
the reservoir. Use only hydraulic brake
fluid conforming to DOT 3 or DOT 4specification.

dangers
Always read the following
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 whencharging 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.
When lifting a plastic-cased bat- tery, excessive pressure on the
case may cause battery acid to
leak, resulting in personal injury.
Lift with a battery carrier or with
your hands on opposite corners.
