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
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
Connections
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 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.

Checking the Engine Oil Level
1. Follow all of the oil manufacturer’s
precautions.
2. Be sure the vehicle is on level ground in P (Park) with the parking
brake set and the wheels blocked.
3. Turn the engine on and allow the engine to reach normal operating
temperature.
4. Turn the engine off and wait about five minutes for the oil to return to
the oil pan.
5. Pull the dipstick out, wipe it clean, and re-insert it fully. 6. Pull the dipstick out again and
check the level. The level should
be between F and L.
7. If it is near or at L, add enough oil to bring the level to F.

Maintenance
To prevent damage to your
engine:
Do not overfill with engine oil.Add oil in small quantities and
recheck level to ensure engine
is not overfilled.
Do not spill engine oil when adding or changing engine oil.
Use a funnel to help prevent oil
from being spilled on engine
components. Wipe off spilled oil
immediately
Use only the specified engine oil
(refer to "Recommended Lubricants
and Capacities" in chapter 8).

WARNING
Engine oil contains chemicals
known to the State of California
to cause cancer, birth defects
and reproductive harm. Used
engine oil may cause irritation
or cancer of the skin if left in
contact with the skin for pro-
longed periods of time. Always
protect your skin by washing
your hands thoroughly with
soap and warm water as soon
as possible after handling used
oil.

Checking the Brake Fluid Level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap
and adding brake fluid, clean the
area around the reservoir cap thor-
oughly to prevent brake fluid contam-
ination. If the level is low, add the specified
brake fluid to the MAX level. The level
will fall with accumulated mileage.
This is a normal condition associated
with the wear of the brake linings. If
the fluid level is excessively low, have
the brake system checked by an
authorized HYUNDAI dealer.
Do not allow brake fluid to con-
tact the vehicle’s body paint, as
paint damage will result.
Brake fluid, which has been exposed to open air for an
extended time should NEVER be
used as its quality cannot be
guaranteed. It should be dis-
posed of properly.
Do not use the wrong kind of brake fluid. A few drops of miner-
al based oil, such as engine oil, in
your brake system can damage
brake system parts.
Information
Use only the specified brake fluid
(refer to "Recommended Lubricants
and Capacities" in chapter 8).
i
NOTICE
If the brake system requires fre-
quent additions of fluid this
could indicate a leak in the
brake system. Have the vehicle
inspected by an authorized
HYUNDAI dealer.
WARNING
Do not allow brake fluid to come
in contact with your eyes. If
brake fluid comes in contact
with your eyes, flush your eyes
with clean water for at least 15
minutes and get immediate
medical attention.

A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver's side panel
bolster, the other in the engine com-
partment near the battery.
If any of your vehicle's lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse. If a fuse
has blown, the element inside the
fuse will be melted or broken.
If the electrical system does not
work, first check the driver's side
fuse panel. Before replacing a blown
fuse, turn the engine and all switches
off, and then disconnect the negative
battery cable. Always replace a
blown fuse with one of the same rat-
ing.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized
HYUNDAI dealer.Information
Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and fusible link for higher
amperage ratings.

Do not use a screwdriver or any
other metal object to remove
fuses because it may cause a
short circuit and damage the
system.
CAUTION
NEVER replace a fuse with any-
thing but another fuse of the
same rating.
A higher capacity fuse could
cause damage and possibly
cause a fire.
Do not install a wire or alu-
minum foil instead of the
proper fuse - even as a tem-
porary repair. It may cause
extensive wiring damage and
possibly a fire.

Maintenance
Waxing
A good coat of wax is a barrier
between your paint and contaminate.
Keeping a good coat of wax on your
vehicle will help protect it.
Wax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle
before waxing. Use a good quality
liquid or paste wax, and follow the
manufacturer’s instructions. Wax all
metal trim to protect it and to main-
tain its luster.
Removing oil, tar, and similar materi-
als with a spot remover will usually
strip the wax from the finish. Be sure
to re-wax these areas even if the rest
of the vehicle does not yet need wax-
ing.
OLMB073082
Water washing in the engine
compartment including high
pressure water washing may
cause the failure of electrical
circuits located in the engine
compartment.
Never allow water or other liq-
uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as
this may damage them.
CAUTION
Do not use strong soap,
chemical detergents or hot
water, and do not wash the
vehicle in direct sunlight or
when the body of the vehicle
is warm.
Be careful when washing the
side windows of your vehicle.
Especially, with high-pressure
water, water may leak through
the windows and wet the inte-
rior.
To prevent damage to the
plastic parts, do not clean
with chemical solvents or
strong detergents.
CAUTION

*2Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel econo my by reducing
the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure in everyday driving, but in a year’s
time, they can offer significant cost and energy savings.

Recommended SAE viscosity
number
Engine oil viscosity (thickness) has
an effect on fuel economy and cold
weather operating (engine start and
engine oil flowability). Lower viscosi-
ty engine oils can provide better fuel
economy and cold weather perform-
ance, however, higher viscosity
engine oils are required for satisfac-
tory lubrication in hot weather. Using
oils of any viscosity other than those
recommended could result in engine
damage.Always be sure to clean the area
around any filler plug, drain
plug, or dipstick before check-
ing or draining any lubricant.
This is especially important in
dusty or sandy areas and when
the vehicle is used on unpaved
roads. Cleaning the plug and
dipstick areas will prevent dirt
and grit from entering the
engine and other mechanisms
that could be damaged.
CAUTION
When choosing an oil, consider the range of temperature your vehicle will be
operated in before the next oil change. Proceed to select the recommended
oil viscosity from the chart.
