Owner maintenance schedule
When you stop for fuel:
•Check the engine oil level.
•Check coolant level in the engine
coolant reservoir.
•Check the windshield washer fluid
level.
•Check 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 if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead position.
•Notice if your vehicle constantly
turns slightly or “pulls” to one side
when traveling 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
operation of your transaxle occurs,
check the transaxle fluid level.
•Check the automatic transaxle
P (Park) function.
•Check the parking brake.
•Check for fluid leaks under your vehi-
cle (water dripping from the air con-
ditioning system during or after use
is normal).
At least monthly:
•Check coolant level in the engine
coolant reservoir.
•Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flashers.
•Check the inflation pressures of all
tires including the spare for tires
that are worn, show uneven wear,
or are damaged.
•Check for loose wheel lug nuts.
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.

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.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.
Fuel filter (cartridge)
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.
We recommend that the fuel filter be
replaced 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. We recommend that the fuel
lines, fuel hoses and connections be
replaced by an authorized HYUNDAI
dealer.
Va p o r h o s e a n d f u e l f i l l e r c a p
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.
When you are inspecting the
belt, place the ignition switch to
the LOCK/OFF or ACC position.

ENGINE OIL
Checking the engine oil level
1. Be sure the vehicle is on level
ground.
2. Start the engine and allow it to
reach normal operating tempera-
ture.
3. Turn the engine off and wait for a
few minutes (about 5 minutes) for
the oil to return to the oil pan.
4. Pull the dipstick out, wipe it clean,
and re-insert it fully.
Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as it may
be hot enough to burn you.

5. Pull the dipstick out again and
check the level. The level should
be between F and L.
•Do not overfill the engine oil.
It may damage the engine.
•Do not spill engine oil, when
adding or changing engine
oil. If you drop the engine oil
on the engine room, wipe it off
immediately.
•When you wipe the oil level
gauge, you should wipe it with
a clean cloth. When mixed
with debris, it can cause
engine damage.

If it is near or at L, add enough oil to bring the level to F.Do not overfill.
Use a funnel to help prevent oil from being spilled on engine compo-
nents.
Use only the specified engine oil. (Refer to “Recommended lubricants and
capacities” in section 8.)
