Maintenance
Vapour hose and fuel filler cap
The vapour hose and fuel filler cap
should be inspected at those intervals
specified in the maintenance schedule.
Make sure that a new vapour hose or fuel
filler cap is correctly 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 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.
Air cleaner filter
A Genuine HYUNDAI air cleaner filter is
recommended when the filter is
replaced.
Spark plugs (for petrol engine)
Make sure to install new spark plugs of
the correct heat range.
Valve clearance (if equipped)
Inspect for excessive valve noise and/or
engine vibration and adjust if necessary.
A HYUNDAI authorised repairer 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.
Manual transaxle fluid
(if equipped)
Inspect the manual transaxle fluid
according to the maintenance schedule.

Maintenance
WASHER FLUID
Checking the washer fluid level
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.
Checking the parking brake
Check the stroke of the parking brake by
counting the number of “clicks’’ heard
whilst 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 a HYUNDAI autho-
rised repairer.
Stroke :6~8 “clicks’’ at a force of
44 lbs (20 kg, 196 N).
PARKING BRAKE
WARNING -Coolant
• Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
• Radiator coolant can severely
obscure visibility when sprayed
on the windscreen and may
cause loss of vehicle control or
damage to the paint and body
trim.
• Windscreen washer fluid agents
contain some amounts of alcohol
and can be flammable under cer-
tain circumstances. Do not allow
sparks or flame come in contact
with the washer fluid or the wash-
er fluid reservoir. Damage to the
vehicle or occupants could
occur.
• Windscreen washer fluid is poi-
sonous to humans and animals.
Do not drink and avoid coming in
contact with the windscreen
washer fluid. Serious injury or
death could occur.

tery cables.
WARNING- Battery
dangers
Always read the following
instructions carefully when

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.
If any electrolyte gets into
your eyes, flush your eyes
with clean water for at least
15 minutes and get immedi-
ate medical attention.
(Continued)
(Continued)
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 dis-
posed battery can be harm-
ful to the environment and
human health.
Dispose the battery accord-
ing to your local law(s) or
regulation.
