ENGINE OIL
WARNING - 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.
CAUTION
Do not overfill with engine oil.
Engine damage may result.
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 temperature.
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. 5. Pull the dipstick out again and check
the level. The level should be between
F and L.
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 components.
Use only the specified engine oil. (Refer to “Recommended lubricants and capaci- ties” in section 8.)

Maintenance
Changing the engine oil and filter
Have engine oil and filter changed by an
authorized HYUNDAI dealer according to
the Maintenance Schedule at the begin-
ning of this section.
CALIFORNIA PROPOSI-
TION 65 WARNING
Engine oil contains chemicals
known to the State of California to
cause cancer, birth defects, and
reproductive harm.
Used engine oil may cause irrita-
tion or cancer of the skin if left in
contact with the skin for prolonged
periods of time. Used engine oil
contains chemicals that have
caused cancer in laboratory ani-
mals. Always protect your skin by
washing your hands thoroughly
with soap and warm water as soon
as possible after handling used oil.

BRAKE FLUID
Checking the brake fluid level
Check the fluid level in the reservoir peri-
odically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir. To check the brake
fluid exactly, after stopping the vehicle,
apply the brake pedal a few times and
then check the fluid level.
Before removing the reservoir cap and
adding brake fluid, clean the area around
the reservoir cap thoroughly to prevent
brake fluid contamination.
If the level is low, add fluid to the MAX
level. The level will fall with accumulated
mileage. This is a normal condition asso-
ciated with the wear of the brake linings.
If the fluid level is excessively low, have
the brake system checked by an author-
ized HYUNDAI dealer.
Use only the specified brake fluid. (Referto “Recommended lubricants or capaci-ties” in section 8.)
Never mix different types of fluid.
WARNING - Brake fluid
When changing and adding brake
fluid, handle it carefully. Do not let it
come in contact with your eyes. If
brake fluid should come in contact
with your eyes, immediately flush
them with a large quantity of fresh
tap water. Have your eyes examined
by a doctor as soon as possible.
WARNING - Loss of brake
fluid
In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized HYUNDAI dealer.CAUTION
Do not allow brake fluid to contactthe vehicle's body paint, as paintdamage will result. Brake fluid,which has been exposed to open air for an extended time should neverbe used as its quality cannot be guaranteed. It should be disposedof properly. Don't put in the wrongkind of fluid. A few drops of miner- al-based oil, such as engine oil, inyour brake system can damage brake system parts.
CAUTION
Do not overfill the brake fluid. Brakesystem damage may occur if thebrake fluid level exceeds the Max fill level.

Clock (See section 4)
Audio (See section 4)WARNING
Before performing maintenance or recharging the 12V battery,
turn off all accessories and stop
the engine.
The negative battery cable must be removed first and installed
last when the 12V battery is dis-
connected.
Operation related to the 12V bat- tery should be done in an author-
ized HYUNDAI dealer.
WARNING- Recharging12V battery
When recharging the battery,
observe the following precautions:
The battery must be removed
from the vehicle and placed in an
area with good ventilation.
Do not allow cigarettes, sparks, or flame near the battery.
Watch the battery during charg- ing, and stop or reduce the charg-
ing rate if the battery cells begin
gassing (boiling) violently or if
the temperature of the electrolyte
of any cell exceeds 120°F (49°C).
Wear eye protection when check- ing the battery during charging.
Disconnect the battery charger in the following order.
1. Turn off the battery charger main switch.
2. Unhook the negative clamp from the negative battery terminal.
3. Unhook the positive clamp from the positive battery terminal.

Cold Tire Pressure: The amount of
air pressure in a tire, measured in
pounds per square inch (psi) or kilo-
pascals (kPa) before a tire has built
up heat from driving.
Curb Weight: This means the weight
of a motor vehicle with standard and
optional equipment including the
maximum capacity of fuel, oil and
coolant, but without passengers and
cargo.
DOT Markings: A code molded into
the sidewall of a tire signifying that
the tire is in compliance with the U.S.
Department of Transportation motor
vehicle safety standards. The DOT
code includes the Tire Identification
Number (TIN), an alphanumeric des-
ignator which can also identify the
tire manufacturer, production plant,
brand and date of production.

air pressure.
Load Index: An assigned number
ranging from 1 to 279 that corre-
sponds to the load carrying capacity

Maintenance
FUSES
A vehicle’s electrical system is protected
from electrical overload damage by fuses.
This vehicle has 2 fuse panels, one locat-
ed in the driver’s side panel bolster, the
other in the engine compartment.
If any of your vehicle’s lights, accessories,
or controls do not work, check the appro-
priate circuit fuse. If a fuse has blown, the
element inside the fuse will be melted.
If the electrical system does not work,
first check the driver’s side fuse panel.Always replace a blown fuse with one of
the same rating.
If the replacement fuse blows, this indi-
cates an electrical problem. Avoid using
the system involved and immediately
consult an authorized HYUNDAI dealer.
Three kinds of fuses are used: blade type
for lower amperage rating, cartridge type,and multi fuse for higher amperage ratings.
✽ ✽ NOTICE
The actual fuse/relay panel label may
differ from equipped items.
WARNING - Fuse
replacement
Never replace a fuse with anything
but another fuse of the same rat-
ing.
A higher capacity fuse could cause damage and possibly a fire.
Never install a wire or aluminum foil instead of the proper fuse -
even as a temporary repair. It may
cause extensive wiring damage
and a possible fire.
CAUTION
Do not use a screwdriver or anyother metal object to remove fusesbecause it may cause a short circuit and damage the system.
CAUTION
When replacing a blown fuse or relay with a new one, make surethe new fuse or relay fits tightly into the clips. The incomplete fas-tening fuse or relay may cause the vehicle wiring and electric sys-tems damage and a possible fire.
Do not remove fuses, relays and terminals fastened with bolts ornuts. The fuses, relays and termi-nals may be fastened incomplete- ly, and it may cause a possiblefire. If fuses, relays and terminals fastened with bolts or nuts areblown, consult with an authorized HYUNDAI dealer.
Do not input any other objects except fuses or relays intofuse/relay terminals such as a driv-er or wiring. It may cause contact failure and system malfunction.
