F010D01A-AAT
General Checks
These 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 6-3.
F010C01A-AAT
Specified Scheduled Procedures
These 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-AAT
Service Requirements
To 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 Requirements
The maintenance required for your Hyundai
can be divided into three main areas:
o Specified scheduled procedures
o General checks
o Do-it-yourself maintenance
F010E01A-AATDo-It-Yourself Maintenance
If 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.

F020A02S-AAT
SCHEDULED MAINTENANCE
REQUIREMENTS
o 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 requi-
rements, see page 5-6 of this section.
F010F01A-AAT
A Few Tips
o Whenever you have your Hyundai serviced,
keep copies of the service records in your
glovebox. This will help assure you can docu-
ment the required procedures being performed
to keep your warranties in effect. This is espe-
cially 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.

MAINTENANCE ITEMS
F060F01A-AATo Vacuum, Crankcase
Ventilation Hoses
Inspect the surface of hoses for evidence of
heat and/or mechanical damage. Hard and
brittle rubber, cracking, tears, cuts, abrasions,
and excessive swelling indicate deterioration.
Particular attention should be paid to examine
those hose surfaces nearest to high heat
sources, such as the exhaust manifold.
Inspect the hose routing to assure that the
hoses do not come in contact with any heat
source, sharp edges or moving component
which might cause heat damage or mechanical
wear. Inspect all hose connections, such as
clamps and couplings, to make sure they are
secure, and that no leaks are present. Hoses
should be replaced immediately if there is any
evidence of deterioration or damage.
F060D01A-AAT
o Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and connec-
tions for leakage and damage. Have a trained
technician replace any damaged or leaking

intervals specified in the maintenance sched-
ule. If the car is being driven in severe condi-
tions, more frequent oil and filter changes are
required.
F060C01A-AAT
o Fuel Filter
A clogged filter can limit the speed at which the
vehicle may be driven, damage the emission
system and cause hard starting. If an exces-
sive amount of foreign matter accumulates in
the fuel tank, the filter may require replacement
more frequently.
After installing a new filter, run the engine for
several minutes, and check for leaks at the
connections. Fuel filters should be installed by
trained technicians.
F060G01A-AAT
o Vapor Hose and Fuel Filler Cap
The vapor hose and fuel filler cap should be
inspected at those intervals specified in the
