Maintenance
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 (MAX) and L (MIN) 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 (MAX), but do not overfill.
If frequent additions are required, we
recommend that the system be
inspected by an authorized HYUNDAI
dealer. 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.
The electric motor (cooling fan)
may operate until you discon-
nect the negative battery cable.

nect the battery cables.
Information
The battery, which is originally
installed in your vehicle, is mainte-
nance free. However, your vehicle is
equipped with a battery marked with
LOWER and UPPER on the side, you
should check the electrolyte level.
The electrolyte level should be
between the LOWER and the
UPPER. When the electrolyte level is
low, add distilled (or de-mineralized)
water. (Never add sulfuric acids or
other electrolyte).
Be careful not to spill distilled (or de-
mineralized) water over the battery
surface or other adjacent components.
Also, do not overfill the battery cells.
If not, it may corrode the battery or
other components. Finally, securely

Your vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes discharged
in a short time (because, for exam-
ple, the headlights or interior lights
were left on while the vehicle was
not in use), recharge it by slow
charging (trickle) for 10 hours.
• If the battery gradually discharges
because of high electric load while
the vehicle is being used, recharge
it at 20-30A for two hours.

FUSES
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.
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 bat-
tery 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 immedi-
ately consult an authorized HYUNDAI
dealer.Information
Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type and multi fuse for higher
amperage ratings.
