CAUTION:
o Radiator antifreeze (engine coolant)
should not be used in the washer system
because it will damage the car's finish.
o The washer lever should not be pulled
and the washer should not be operated
if the washer reservoir is empty. This can
damage the washer fluid pump.
!
A good quality washer fluid should be used to fill
the washer reservoir. The fluid level should be
checked more frequently during bad weather or
whenever the washer system is in more fre-
quent use.
The capacity of the washer reservoir is 3.2 U.S.
quarts (4.0 liters).
!
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.

CHECKING THE TRANSAXLE
FLUID (AUTOMATIC)G110A01E-AATTransaxle fluid in the automatic transaxle should
be checked at those intervals specified in the
vehicle maintenance schedule in Section 5.NOTE:Automatic transaxle fluid is basically red in
color. As driving distance increases, the
fluid color turns darkish red gradually. It is
a normal condition and you should not
judge the need to replace based upon the
changing color.
You must replace the automatic transaxle
fluid in accordance with intervals specified
in the vehicle maintenance schedule in
section 5.
!
G110B05A-AATRecommended FluidYour Hyundai automatic transaxle is specially
designed to operate with HYUNDAI GENUINE
ATF SP III, DIAMOND ATF SP III, SK ATF SP
III or other brands meeting the SP III specifica-
tion approved by Hyundai Motor Co.. Damage
caused by a nonspecified fluid is not covered by
your new vehicle limited warranty.
CAUTION:
Use of aftermarket ATF additives may cause
damage to the automatic transaxle.
Only use HYUNDAI GENUINE ATF SP III,
DIAMOND ATF SP III, SK ATF SP III or other
brands meeting the SP III specification ap-
proved by Hyundai Motor Co.. If you are
having your vehicle serviced at a facility
other than a Hyundai dealer, verify that the
correct ATF is used for your vehicle.
G100B02A-AATTo Check the Manual Transaxle
Fluid Level
G100B01L
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 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.

G240A01A-AATPOWER STEERING HOSESIt is suggested that you check the power steer-
ing hose connections for fluid leakage at those
intervals specified in the vehicle maintenance
schedule in Section 5.
The power steering hoses should be replaced
if there is severe surface cracking, pulling,
scuffing or worn spots. Deterioration of the hose
could cause premature failure.
POWER STEERING FLUID LEVELG230A03A-AAT
to make certain that the power steering fluid
level is between the "MAX" and "MIN" level
markings on the fluid reservoir.NOTE:Grinding noise from the power steering
pump may be heard immediately after the
engine is started in extremely cold condi-
tions (below - 4°F). If the noise stops during
warm up, there is no abnormal function in
the system. It is due to a power steering
fluid characteristic in extremely cold condi-
tions.
Recommended Fluid
Use PSF-3 type fluidNOTE:Do not start the engine when the power
steering oil reservoir is empty.

obtaining a better understanding of your car and
how it works.

regularly. To check the power steering fluid
level, be sure the engine is "OFF", then check
