ENGINE COOLANT
The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at
the beginning of the winter season,
and before traveling to a colder cli-
mate.
Checking the coolant level
(Continued)
Turn the engine off and waituntil it cools down. Use
extreme care when removing
the radiator cap. Wrap a thick
towel around it, and turn it
counterclockwise slowly to
the first stop. Step back while
the pressure is released from
the cooling system. When you
are sure all the pressure has
been released, press down on
the cap, using a thick towel,
and continue turning counter-
clockwise to remove it.
Even if the engine is not oper- ating, do not remove the radia-
tor cap or the drain plug while
the engine and radiator are
hot. Hot coolant and steam
may still blow out under pres-
sure, causing serious injury.WARNING
The electric motor
(cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure
and vehicle speed. It may some-
times operate even when the
engine is not running. Use
extreme caution when working
near the blades of the cooling
fan so that you are not injured
by a rotating fan blades. As the
engine coolant temperature
decreases, the electric motor
will automatically shut off. This
is a normal condition.
WARNING
Removing radiator
cap
Never attempt to remove the radiator cap while the engine
is operating or hot. Doing so
might lead to cooling system
and engine damage and could
result in serious personal
injury from escaping hot
coolant or steam.

Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between F and L marks on the side
of the coolant reservoir when the
engine is cool.
If the coolant level is low, add enough
distilled (deionized) water. Bring the
level to F, but do not overfill. If fre-
quent additions are required, see an
authorized HYUNDAI dealer for a
cooling system inspection.
Recommended engine coolant
When adding coolant, use only
deionized water or soft water for
your vehicle and never mix hard
water in the coolant filled at the fac-
tory. An improper coolant mixture
can result in serious malfunction or
engine damage.
The engine in your vehicle has alu- minum engine parts and must be
protected by an ethylene-glycol
with phosphate based coolant to
prevent corrosion and freezing.
DO NOT USE alcohol or methanol coolant or mix them with the spec-
ified coolant.
Do not use a solution that contains more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of the
solution. For mixture percentage, refer to the
following table.

BRAKE/CLUTCH FLUID
Checking the brake/clutch
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/clutch fluid, clean
the area around the reservoir cap
thoroughly to prevent brake/clutch
fluid contamination. If the level is low, add fluid to the MAX
level. The level will fall with accumu-
lated mileage. This is a normal condi-
tion associated with the wear of the
brake linings. If the fluid level is
excessively low, have the brake sys-
tem or clutch (if equipped) checked
by an authorized HYUNDAI dealer.
Use only the specified brake fluid.
(Refer to “Recommended lubricantsor capacities” in section 8.)
Never mix different types of fluid.
WARNING - Brake/clutch
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/
clutch 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 con- tact the vehicle's body paint, aspaint damage will result. Brakefluid, which has been exposedto open air for an extended timeshould never be used as itsquality cannot be guaranteed. Itshould be disposed of properly.Don't put in the wrong kind offluid. A few drops of mineral-based oil, such as engine oil, inyour brake system can damagebrake system parts.

FUSES
The electrical system is protected by
fuses.
This vehicle has 2 fuse panels, one
located in the driver’s side panel bol-
ster, the other in the engine compart-
ment.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse.
If the electrical system does not work,
first check the driver’s side fuse panel.
Always replace an open fuse with
one of the same rating.
Before replacing an open fuse, dis-
connect the negative battery cable.
If the replacement fuse opens, this
indicates an electrical malfunction.
Avoid using the system involved and
immediately consult an authorized
HYUNDAI dealer.
Three kinds of fuses are used: bladetype for lower amperage rating, car-tridge type, and multi fuse for higheramperage ratings.
WARNING - Fuse
replacement
Never replace a fuse with any- thing but another fuse of the
same rating.
A higher capacity fuse could cause damage and possibly a
fire.
Never 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
a possible fire.
CAUTION
Do not use a screwdriver or anyother metal object to removefuses because it may cause ashort circuit and damage thesystem.
