WARNING:
It is recommended that the engine be cool
or cold when changing the spark plugs. If
the engine is hot, you could burn yourself
on the insulated connector, the spark plug
or the engine itself. 6. Remove the mounting bolt (3) of the ignition
coil with a socket wrench.
7. Pull straight up on the ignition coil (4).

8. When preparing to remove the spark plug,
guide the socket down over the spark plug,
being careful not to damage the ceramic
insulator.
9. To remove the spark plug, turn the wrench
handle in a counterclockwise direction. (3)

2. Open the fuse box and examine each fuse.
Remove each fuse by pulling it toward you
(a small "fuse puller" tool is contained in the
relay and fuse box of the engine room to
simplify this operation).
3. Be sure to check all other fuses even if you
G200B02NF
find one that appears to have burned out.
4. Replace the blown fuse by pressing a new
fuse of the same rating into place. The fuse
should be a snug fit. If it is not, have the fuse
clip repaired or replaced by a Hyundai dealer.
If you do not have a spare fuse, you may be
able to borrow a fuse of the same or lower
rating from an accessory you can tempo-
rarily get along without (the radio or cigarette
lighter, for example). Always remember to
replace the borrowed fuse.

G200B02L
GoodBurned outCAUTION:
A burned-out fuse indicates that there is a
problem in the electrical circuit. If you re-
place a fuse and it blows as soon as the
accessory is turned on, the problem is
serious and should be referred to a Hyundai
dealer for diagnosis and repair. Never re-
place a fuse with anything except a fuse
with the same or a lower amperage rating.
A higher capacity fuse could cause damage
and create a fire hazard.NOTE:See page 6-39 for the fuse panel descrip-
tions.
G200B01NF-GATReplacing Accessory Fuse
G200B01NF-A
The fuse box for the lights and other electrical
accessories will be found on the left side of the
instrument panel. Inside the box you will find a
list showing the circuits protected by each fuse.
If any of your car's lights or other electrical
accessories stop working, a blown fuse could
be the reason. If the fuse has burned out, you
will see that the metal strip inside the fuse has
burned through. If you suspect a blown fuse,
follow this procedure:
1. Turn off the ignition and all other switches.

WARNING:Always read the following in-
structions carefully when han-
dling a battery.
Keep lighted cigarettes and all
other flames or sparks away from
the battery.
Hydrogen, which is a highly com-
bustible gas, is always present in
battery cells and may explode if
ignited.
Keep batteries out of the reach of
children because batteries con-
tain highly corrosive SULFURIC
ACID. Do not allow battery acid
to contact your skin, eyes, cloth-
ing or paint finish.
If any electrolyte gets into your
eyes, flush your eyes with clean
water for at least 15 minutes and
get immediate medical attention.
If possible, continue to apply
water with a sponge or cloth until
medical attention is received.If electrolyte gets on your skin,
thoroughly wash the contacted
area.
If you feel a pain or a burning
sensation, get medical attention
immediately.
Wear eye protection when charg-
ing or working near a battery.
Always provide ventilation when
working in an enclosed space.
o When lifting a plastic-cased battery, ex-
cessive pressure on the case may cause
battery acid to leak, resulting in personal
injury. Lift with a battery carrier or with
your hands on opposite corners.
o Never attempt to charge the battery when
the battery cables are connected.
o The electrical ignition system works with
high voltage.
Never touch these components with the
engine running or the ignition switched
on.
WARNING:
CHECKING ELECTRIC COOLING
FANS!
G220A01A-AAT
WARNING:
The cooling fan is controlled by engine
coolant temperature and may sometimes
operate even when the engine is not run-
ning. Use extreme caution when working
near the blades of the cooling fan, so that
you are not injured by a rotating fan blade.
As the engine coolant temperature de-
creases the fan will automatically shut off.
This is a normal condition.G220B01NF-GATChecking Engine Cooling FanThe engine cooling fan should come on auto-
matically if the engine coolant temperature is
high or whenever the air conditioning is in
operation.
