Recommended Fluid
Your Hyundai automatic transaxle is specially
designed to operate with HYUNDAI GENUINE
ATF or DIAMOND ATF SP-III or SK ATF SP-III.
Damage caused by a nonspecified fluid is not
covered by your new vehicle limited warranty.
G110A01A-AAT
CHECKING THE TRANSAXLE FLUID
(AUTOMATIC)
Transaxle fluid in the automatic transaxle should
be checked at those intervals specified in the
vehicle maintenance schedule in Section 5.

Level
G100A03Y-AATCHECKING THE TRANSAXLE OIL
(MANUAL)
Transaxle lubricant in the manual transaxle
should be checked at those intervals specified
in the vehicle maintenance schedule in Section
5.
Recommended Oil
Use only HYUNDAI GENUINE PARTS MTF
75W/90 (API GL-4) or equivalent in the manual
transaxle.
Manual Transaxle Oil Capacity
The oil capacity of the manual transaxle is 2.2
U.S. quarts (2.1 liters).Park the car on level ground with the engine off.
1. Using a wrench of the correct size, loosen
the oil filler plug by turning it counterclock-
wise and remove it with your fingers.2. Use your finger or suitable tool to feel inside
the hole. The oil level should be at its bottom
edge. If it is not, check for leaks before
adding oil. To refill the transaxle or bring the
oil level up,add oil slowly until it reaches the
proper level. Do not overfill.
3. Replace the plug and washer, screw it in with
your fingers and then tighten securely with
the wrench.
WARNING:It is always better to check the transaxle oil
level when the engine is cool or cold. If the
engine is hot, you should exercise great
caution to avoid burning yourself on hot
engine or exhaust parts.

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.
2. Open the instrument panel junction box and
examine each fuse. Remove each fuse by
pulling it toward you (a small "fuse puller" tool
is contained in the fuse box to simplify this
operation).
3. Be sure to check all other fuses even if you
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.

G210A01A-AATCHECKING THE BATTERY
WARNING:
Batteries can be dangerous! When working
with batteries, carefully observe the follow-
ing precautions to avoid serious injuries.
The fluid in the battery contains a strong solution
of sulfuric acid, which is poisonous and highly
corrosive. Be careful not to spill it on yourself or
the car. If you do spill battery fluid on yourself,
immediately do the following:
o If battery fluid is on your skin, flush the
affected areas with water for at least 15
minutes and then seek medical assistance.
o If battery fluid is in your eyes, rinse out your
eyes with water and get medical assistance
as soon as possible. While you are being
driven to get medical assistance, continue to
rinse your eyes by using a sponge or soft
cloth saturated with water.
o If you swallow battery fluid, drink a large
quantity of water or milk followed by milk of
magnesia, eat a raw egg or drink vegetable
oil. Get medical assistance as soon as
possible. 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.
CAUTION: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 6-29 for the junction box descrip-
tions.

G250A01A-AATFOR MORE INFORMATION ABOUT
YOUR HYUNDAI
If you desire additional information about main-
taining and servicing your Hyundai, you may
purchase a factory Shop Manual at your Hyundai
dealer's parts department. This is the same
manual used by dealership technicians and
while it is highly technical it can be useful in
obtaining a better understanding of your car and
how it works.
G240A01A-AATPOWER STEERING HOSES
It is suggested that you check the power steer-
ing hose connections for fluid leakage at regular
intervals. The power steering hoses should be
replaced if there is severe surface cracking,
scuffing or worn spots. Deterioration of the hose
could cause premature failure. Recommended Fluid
Use PSF-3 type fluid
NOTE:Do not start the engine when the power
steering oil reservoir is empty.
G260A02A-AATREPLACING HEADLIGHT BULBS
Before attempting to replace a headlight bulb, be
sure the switch is turned to the "OFF" position.
The next paragraph shows how to reach head-
light bulbs so they may be changed. Be sure to
replace the burned-out bulb with one of the
same number and wattage rating.
!CAUTION:Keep the lamps out of contact with petro-
leum products such as oil, gasoline etc.
