Maintenance
The electric motor for the cooling fan
is controlled by engine coolant tem-
perature, refrigerant pressure and
vehicle speed. As the engine coolant
temperature decreases, the electric
motor will automatically shut off. This
is a normal condition. If your vehicle
is equipped with GDI, the electric
motor for the cooling fan may begin
to operate at any time and continue
to operate until you disconnect the
negative battery cable. Never remove the
engine coolant reser-
voir tank/radiator cap
or the drain plug
while the engine and
radiator are hot. Hot coolant
and steam may blow out under
pressure, causing serious
injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the engine coolant reservoir
tank/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 counterclock-
wise to remove it.
WARNING
The electric motor for
the cooling fan may
continue to operate
or start up when the
engine is not running
and can cause serious injury.
Keep hands, clothing and tools
away from the rotating fan
blades of the cooling fan.
WARNING
Make sure the coolant cap is
properly closed after refilling
coolant. Otherwise the engine
could be overheated while driv-
ing.
1. Check if the coolant cap label
is straight In front.

To prevent SERIOUS INJURY or
DEATH to you or bystanders,
always follow these precautions
when working near or handling
the battery:
Always read and follow
instructions carefully
when handling a battery.
Wear eye protection
designed to protect the
eyes from acid splashes.
Keep all flames, sparks,
or smoking materials
away from the battery.
Hydrogen is always pres-
ent in battery cells, is
highly combustible, and
may explode if ignited.
Keep batteries out of
reach of children.
WARNING Batteries contain sulfu-
ric acid which is highly
corrosive. Do not allow
acid to contact your
eyes, skin or clothing.
If acid gets into your eyes, flush
your eyes with clean water for at
least 15 minutes and get imme-
diate medical attention. If acid
gets on your skin, thoroughly
wash the area. If you feel pain or
a burning sensation, get med-
ical attention immediately.
When lifting a plastic-cased
battery, excessive pressure
on the case may cause battery
acid to leak. Lift with a battery
carrier or with your hands on
opposite corners.
Do not attempt to jump start
your vehicle if your battery is
frozen.
NEVER attempt to recharge
the battery when the vehicle’s
battery cables are connected
to the battery.
The electrical ignition system
works with high voltage.
NEVER touch these compo-
nents with the engine running
or when the ignition switch is
in the ON position.

Maintenance
When you do not use the vehicle
for a long time in a low tempera-
ture area, disconnect the battery
and keep it indoors.
Always charge the battery fully
to prevent battery case damage
in low temperature areas.
For Best Battery Service
Keep the battery securely mount-
ed.
Keep the battery top clean and dry.
Keep the terminals and connec-
tions clean, tight, and coated with
petroleum jelly or terminal grease.
Rinse any spilled acid from the bat-

Watch the battery during
charging, and stop or reduce
the charging rate if the battery
cells begin boiling violently.
The negative battery cable
must be removed first and
installed last when the battery
is disconnected. Disconnect
the battery charger in the fol-
lowing order:
(1) Turn off the battery charg-
er main switch.

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
Four kinds of fuses are used : blade
type For lower amperage rating, car-
tridge type/Multi fuse/Battery fuse
terminal 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 sys-
tem.
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 alu-
minum foil instead of the
proper fuse - even as a tem-
porary repair. It may cause
extensive wiring damage and
possibly a fire.
