VEHICLE MAINTENANCE REQUIREMENTS2
F010C01A-AATSpecified Scheduled ProceduresThese are the procedures such as inspections,
adjustments and replacements that are listed in
the maintenance charts starting on page 5-4.
These procedures must be performed at the
intervals shown in the maintenance schedule to
assure that your warranty remains in effect.
Although it is strongly recommended that they
be performed by the trained technicians at your
Hyundai dealer, these procedures may be per-
formed at any qualified service facility.
It is suggested that genuine Hyundai service
parts be used for any required repairs or re-
placements. Other parts of equivalent quality
such as engine oil, engine coolant, manual or
auto transaxle oil, brake fluid and so on which
are not supplied by Hyundai Motor Company or
its distributor may be used without affecting
your warranty coverage but you should always
be sure these are equivalent to the quality of the
original Hyundai parts. Your Owner's Hand-
book provides further information about your
warranty coverage.
F010A01A-AATService RequirementsTo ensure that you receive the greatest number
of miles of satisfying operation from your Hyundai,
certain maintenance procedures must be per-
formed. Although careful design and engineer-
ing have reduced these to a minimum, those that
are required are of the utmost importance.
It is your responsibility to have these mainte-
nance procedures performed to comply with
the terms of the warranties covering your new
Hyundai. The Owner's Handbook supplied with
your new vehicle provides further information
about these warranties.
F010B01A-AATMaintenance RequirementsThe maintenance required for your Hyundai
can be divided into three main areas:
o Specified scheduled procedures
o General checks
o Do-it-yourself maintenance

SCHEDULED MAINTENANCE
REQUIREMENTSF020A02Y-AATo Inspection should be performed any time a
malfunction is experienced or suspected.
o Receipts for all emission control system
services should be retained to demonstrate
compliance with conditions of the emissions
system warranty.
o After 120 months or 150,000 miles (240,000
km), continue to follow the prescribed main-
tenance intervals.
o For severe usage maintenance require-
ments, see page 5-6 of this section.
F010D02A-AATGeneral ChecksThese are the regular checks you should per-
form when you drive your Hyundai or you fill the
fuel tank. A list of these items will be found on
page 6-4.F010E01A-AATDo-It-Yourself MaintenanceIf you are mechanically inclined, own a few tools
that are required and want to take the time to do
so, you can inspect and service a number of
items. For more information about doing it your-
self, see Section 6.
F010F01A-AATA Few Tipso Whenever you have your Hyundai serviced,
keep copies of the service records in your
glove box. This will help ensure that you can
document that the required procedures have
been performed to keep your warranties in
effect. This is especially important when
service is not performed by an authorized
Hyundai dealer.
o If you choose to do your own maintenance
and repairs, you may find it helpful to have
an official Hyundai Shop Manual. A copy of
this publication may be purchased at your
Hyundai dealer's parts department.

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

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.
