OWNER MAINTENANCE
The following lists are vehicle checks and
inspections that should be performed by
the owner or an authorized HYUNDAI
dealer at the frequencies indicated to
help ensure safe, dependable operation
of your vehicle.
Any adverse conditions should be
brought to the attention of your dealer as
soon as possible.
These Owner Maintenance Checks are
generally not covered by warranties and
you may be charged for labor, parts and
lubricants used.Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check coolant level in coolant reser-
voirs (engine and inverter).
Check the windshield washer fluid
level.
Look for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound of the
exhaust or any smell of exhaust fumes
in the vehicle.
Check for vibrations in the steering
wheel. Notice any increased steering
effort or looseness in the steering
wheel, or change in its straight-ahead
position.
Notice if your vehicle constantly turns
slightly or “pulls” to one side when trav-
eling on smooth, level road.
When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
If any slipping or changes in the oper-
ation of your transaxle occurs, check
the transaxle fluid level.
Check automatic transaxle P (Park)
function.
Check parking brake.
Check for fluid leaks under your vehicle
(water dripping from the air condition-
ing system during or after use is nor-
mal).
Check inverter coolant.
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot coolant
and steam may blow out under
pressure. This could cause burns
or other serious injury.

At least monthly:
Check coolant level in the engine
coolant reservoir and inverter coolant.
Check the operation of all exterior
lights, including the stoplights, turn sig-
nals and hazard warning flashers.

tires including the spare.
At least twice a year
(i.e., every Spring and Fall):
Check radiator, heater and air condi-
tioning hoses for leaks or damage.
Check windshield washer spray and
wiper operation. Clean wiper blades
with clean cloth dampened with wash-
er fluid.
Check headlight alignment.
Check muffler, exhaust pipes, shields
and clamps.
Check the lap/shoulder belts for wear
and function.
Check for worn tires and loose wheel
lug nuts.
At least once a year:
Clean body and door drain holes.
Lubricate door hinges and checks, and
hood hinges.
Lubricate door and hood locks and
latches.
Lubricate door rubber weatherstrips.
Check the air conditioning system.
