WARNING
Performing maintenance work on a
vehicle can be dangerous. 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.
ALWAYS follow these precautions for
performing maintenance work:

[Park your vehicle on level ground,
move the shift lever into the P (Park)
position, place the ignition switch in
the LOCK/OFF position.

[ Block the tires (front and back) to
prevent the vehicle from moving.
Remove loose clothing or jewelry
that can become entangled in
moving parts.

[ If you must run the engine during
maintenance, do so in an outdoor
area or in an area with plenty of
ventilation.

[ Keep flames, sparks, or smoking
materials away from the battery and
fuel-related parts. 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 vehicle
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 coolant level in the engine
coolant reservoir.

[ Check the windshield washer fluid
level.

[ Check the for low or under-inflated
tires.

[ Check the radiator and condenser.

[ Check if the front of the radiator and
condenser are clean and not blocked
with leaves, dirt or insects etc. If any
of the above parts are extremely dirty
or you are not sure of their condition,
we recommend that you contact an
authorized HYUNDAI dealer.

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.
OWNER MAINTENANCE

Maintenance9-14
Engine Oil and Filter
The engine oil and filter should be
changed at the intervals specified in the
maintenance schedule. If the vehicle
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 periodically
for proper tension and adjusted as
necessary.
Fuel Filter
A clogged-up fuel filter may limit the
vehicle driving speed, damage the
emission system, and cause the hard
starting. When a considerable amount
of foreign substances are accumulated
in the fuel tank, the fuel filter should be
replaced.
Upon installing a new fuel filter, operate
the engine for several minutes, and
check the connections for any leakages.
Fuel filters should be installed by an
authorized HYUNDAI dealer.
HSG (Hybrid Starter & Generator)
Belt
The HSG belt should be changed at the
intervals specified in the maintenance
schedule.
Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and
connections for leakage and damage.
Have an authorized HYUNDAI dealer
replace any damaged or leaking parts
immediately.
Vapor Hose and Fuel Filler Cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
a new vapor hose or fuel filler cap is
correctly replaced.
Air Cleaner Filter
A genuine HYUNDAI air cleaner filter
is recommended when the filter is
replaced.
Spark Plugs
Make sure to install new spark plugs of
the correct heat range.
When assembling parts, be sure to
wipe out foreign substances inside
and outside of the boot bottom of the
ignition coil and the insulator of the
spark plug with a soft cloth to prevent
contamination of the spark plug
insulator.
Cooling System
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.

Maintenance9-54
Consult an authorized HYUNDAI dealer
to replace most vehicle light bulbs. It is
difficult to replace vehicle light bulbs
because other parts of the vehicle must
be removed before you can get to the
bulb. This is especially true for removing
the headlight assembly to get to the
bulb(s).
Removing/installing the headlight
assembly can result in damage to the
vehicle.
Information
The headlight and tail lamp lenses could
appear frosty if the vehicle is washed after
driving or the vehicle is driven at night in
wet weather. This condition is caused by
temperature difference between the lamp
inside and outside and does not indicate
a problem with your vehicle. When
moisture condenses in the lamp, it will be
removed after driving with the headlight
on. The removable level may differ
depending on lamp size, lamp position
and environmental condition. However, if
moisture is not removed, have the vehicle
inspected by an authorized HYUNDAI
dealer.
WARNING

[ Prior to replacing a lamp, depress the
foot brake, move the shift lever into P
(Park) apply the parking brake, place
the ignition switch to the LOCK/OFF
position, and take the key with you
when leaving the vehicle to avoid
sudden movement of the vehicle and
to prevent possible electric shock.

[ Be aware the bulbs may be hot and
may burn your fingers.

[ When the bulb is disconnected or the
lamp connector is removed while the
lamp is operating normally, the fuse
box electronics may recognize the
lamp as a malfunction. Therefore, a
fault record for the lamp may remain
in the Diagnostic Trouble Code (DTC)
recorded in the fuse box.
