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-voir.
 Check the windshield washer fluid level.
 Look for low or under-inflated tires.
WARNING
- Maintenance work
 Performing maintenance work on
a vehicle can be dangerous. You
can be seriously injured while
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, have it done by an
authorized HYUNDAI dealer.
 Working under the hood with the engine running is dangerous. It
becomes even more dangerous
when you wear jewelry or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine while work-
ing under the hood, make certain
that you remove all jewelry (espe-
cially rings, bracelets, watches,
and necklaces) and all neckties,
scarves, and similar loose cloth-
ing before getting near the
engine or cooling fans.
OWNER MAINTENANCE
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.

Maintenance67While operating your vehicle: Note any changes in the sound of theexhaust 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).
At least monthly: Check coolant level in the enginecoolant reservoir.
 Check the operation of all exterior lights, including the stoplights, turn sig-
nals and hazard warning flashers.
 Check the inflation pressures of all 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, andhood hinges.
 Lubricate door and hood locks and latches.
 Lubricate door rubber weatherstrips.
 Check the air conditioning system.
 Inspect and lubricate automatic transaxle linkage and controls.
 Clean battery and terminals.
 Check the brake fluid level.
