Changing Engine Coolant
Have coolant changed by an authorized
HYUNDAI dealer according to the
Maintenance Schedule at the beginning
of this chapter.
To prevent damage to engine parts,
put a thick towel around the radiator
cap before refilling the coolant to pre-
vent the coolant from overflowing into
engine parts, such as the generator.
Checking the Brake/Clutch
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.
Before removing the reservoir cap and
adding brake/clutch fluid, clean the area
around the reservoir cap thoroughly to
prevent brake/clutch fluid contamination.
If the level is low, add the specified
brake/clutch fluid to the MAX level. The
level will fall with accumulated mileage.
This is a normal condition associated
with the wear of the brake/clutch linings.
If the fluid level is excessively low, have
the brake/clutch system checked by an
authorized HYUNDAI dealer.
NOTICE
Do not use engine coolant or
antifreeze in the washer fluid reser-
voir.
Engine coolant can severely
obscure visibility when sprayed on
the windshield and may cause loss
of vehicle control resulting in an
accident.
Engine coolant may also cause
damage to paint and body trim.
WARNING
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/clutch fluid to
come in contact with your eyes. If
brake/clutch fluid comes in contact
with your eyes, flush your eyes with
clean water for at least 15 minutes
and get immediate medical atten-
tion.

Do not allow brake/clutch fluid to
contact the vehicle's body paint, as
paint damage will result.
Brake/clutch 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 disposed of properly.
Do not use the wrong kind of brake/clutch fluid. A few drops of
mineral based oil, such as engine
oil, in your brake/clutch system can
damage brake/clutch system parts.
Information
Use only the specified brake/clutch fluid
(refer to "Recommended Lubricants and
Capacities" in chapter 8).
Checking the Washer Fluid
Level
Check the fluid level in the washer fluid
reservoir and add fluid if necessary. Plain
water may be used if washer fluid is not
available. However, use washer solvent
with antifreeze characteristics in cold cli-
mates to prevent freezing.i
NOTICE
OAD075011
To prevent serious injury or death,
take the following safety precau-
tions when using washer fluid:
Do not use engine coolant or
antifreeze in the washer fluid
reservoir.
Engine coolant can severely
obscure visibility when sprayed
on the windshield and may cause
loss of vehicle control resulting
in an accident or damage to paint
and body trim.
Do not allow sparks or flame to
contact the washer fluid or the
washer fluid reservoir. Washer
fluid may contain alcohol and can
be flammable.
Do not drink washer fluid and
avoid contact with skin. Washer
fluid is harmful to humans and
animals.
Keep washer fluid away from chil-
dren and animals.

A vehicle’s electrical system is protected
from electrical overload damage by
fuses.
This vehicle has 2 (or 3) fuse panels, one
located in the driver's side panel bolster,
the other in the engine compartment
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 dis-
connect the negative battery cable.
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.
Information
Four kinds of fuses are used : blade type
for lower amperage rating, cartridge type/
Multi fuse/Battery fuse terminal for high-
er amperage ratings. Do not use a screwdriver or any other
metal object to remove fuses because
it may cause a short circuit and dam-
age the system.
NOTICE
i
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 aluminum
foil instead of the proper fuse -
even as a temporary repair. It may
cause extensive wiring damage
and possibly a fire.

Instrument Panel Fuse
Replacement
1. Turn the engine off.
2. Turn all other switches OFF.
3. Open the fuse panel cover.
4. Refer to the label on the inside of thefuse panel cover to locate the sus-
pected fuse location. 5. Pull the suspected fuse straight out.
Use the removal tool provided in the
engine compartment fuse panel.
6. Check the removed fuse; replace it if it is blown. Spare fuses are provided in
the instrument panel fuse panels (or in
the engine compartment fuse panel).
7. Push in a new fuse of the same rating, and make sure it fits tightly in the clips.
If it fits loosely, consult an authorized
HYUNDAI dealer. In an emergency, if you do not have a
spare fuse, use a fuse of the same rating
from a circuit you may not need for oper-
ating the vehicle.
If the headlamps or other electrical com-
ponents do not work and the fuses are
OK, check the fuse panel in the engine
compartment. If a fuse is blown, it must
be replaced with the same rating.

Maintenance
Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in the
canister are drawn into the surge tank
through the purge control solenoid valve.
Purge Control Solenoid Valve(PCSV)
The purge control solenoid valve is con-
trolled by the Engine Control Module
(ECM); when the engine coolant temper-
ature is low during idling, the PCSV clos-
es so that evaporated fuel is not taken
into the engine. After the engine warms-
up during ordinary driving, the PCSV
opens to introduce evaporated fuel to the
engine.
3. Exhaust Emission Control System
The Exhaust Emission Control System is
a highly effective system which controls
exhaust emissions while maintaining
good vehicle performance.
When the engine starts or fails to start,
excessive attempts to restart the engine
may cause damage to the emission sys-
tem.
Engine exhaust (carbon monox-
ide) precautions
Carbon monoxide can be present with
other exhaust fumes. If you smell
exhaust fumes of any kind in your vehi-
cle, drive with all the windows fully
open. Have your vehicle checked and
repaired immediately.
Engine exhaust gases contain car-
bon monoxide (CO). Though color-
less and odorless, it is dangerous
and could be lethal if inhaled.
Follow the instructions on this
page to avoid CO poisoning.
WARNING
CALIFORNIA PROPOSITION 65

Specifications, Consumer information and Reporting safety defects
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 viscosity engine oils
can provide better fuel economy and cold
weather performance, however, higher
viscosity engine oils are required for sat-
isfactory lubrication in hot weather.Using oils of any viscosity other than
those recommended could result in
engine damage.
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.
Always be sure to clean the area
around any filler plug, drain plug, or
dipstick before checking or drain-
ing 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.
