NORMAL MAINTENANCE SCHEDULE
The following maintenance services must be performed to ensure good emission control and performance. Keep
receipts for all vehicle emission services to protect your warranty. Where both mileage and time are shown, the fre-
quency of service is determined by whichever occurs first.
*
1: Check the engine oil level and leak every 350 miles(500 km) or before starting a long trip.
*
2: The drive belt should be replaced when cracks occur or tension is reduced excessively.
*
3: If TOP TIER Detergent Gasoline is not available, one bottle of additive is recommended. Additives are
available from your authorized HYUNDAI dealer
along with information on how to use them. Do not
mix other additives.
*
4: Rear differential oil should be changed anytime they have been submerged in water.
*
5: Fuel filter & Fuel tank air filter are considered to be maintenance free but periodic inspection is recom-
mended for this maintenance schedule depends on
fuel quality. If there are some important safety matters
like fuel flow restriction, surging, loss of power, hard
starting problem etc, replace the fuel filter immediately
regardless of maintenance schedule and consult an
authorized HYUNDAI dealer for details. *
6: When adding coolant, use only deionized water or
soft water for your vehicle and never mix hard water
in the coolant filled at the factory. An improper coolant
mixture can result in serious malfunction or engine
damage.
*

EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the car
is being driven in severe conditions,
more frequent oil and filter changes
are required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Fuel filter
A clogged filter can limit the speed at
which the vehicle may be driven,
damage the emission system and
cause multiple issues such as hard
starting. If an excessive amount of
foreign matter accumulates in the
fuel tank, the filter may require
replacement more frequently.
After installing a new filter, run the
engine for several minutes, and
check for leaks at the connections.
Fuel filters should be installed by an
authorized HYUNDAI dealer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. Have an authorized HYUNDAI
dealer replace any damaged or leak-
ing parts immediately.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure that a new
vapor hose or fuel filler cap is cor-
rectly replaced.
Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. 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 con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.

Filter inspection
The climate control air filter should
be replaced according to the
Maintenance Schedule. If the vehicle
is operated in severely air-polluted
cities or on dusty rough roads for a
long period, it should be inspected
more frequently and replaced earlier.

air filter, replace it performing the fol-
lowing procedure, and be careful to
avoid damaging other components.
Filter replacement
1. Open the glove box and removethe support rod (1).
