2004 Hyundai Elantra maintenance

2DRIVING YOUR HYUNDAI
14SMOOTH CORNERING
o Remember, your Hyundai does not require
extended warm-up. As soon as the engine
is running smoothly, you can drive away. In
very cold weather, however, give your en-
gine a slightly longer warm-up period.
o Don't "lug" or "over-rev" the engine. Lugging
is driving too slowly in too high a gear result-
ing in the engine bucking. If this happens,
shift to a lower gear. Over-revving is racing
the engine beyond its safe limit. This can be
avoided by shifting at the recommended
speeds.
o Use your air conditioning sparingly. The air
conditioning system is operated by engine
power so your fuel economy is reduced
when you use it.C150A01A-AAT
Avoid braking or gear changing in corners,
especially when roads are wet. Ideally, corners
should always be taken under gentle accelera-
tion. If you follow these suggestions, tire wear
will be held to a minimum. o Be sure that the wheels are aligned cor-
rectly. Improper alignment can result from
hitting curbs or driving too fast over irregular
surfaces. Poor alignment causes faster tire
wear and may also result in other problems
as well as greater fuel consumption.
o Keep your car in good condition. For better
fuel economy and reduced maintenance
costs, maintain your car in accordance with
the maintenance schedule in Section 5. If
you drive your car in severe conditions,
more frequent maintenance is required (see
Section 5 for details).
o Keep your car clean. For maximum service,
your Hyundai should be kept clean and free
of corrosive materials. It is especially impor-
tant that mud, dirt, ice, etc. not be allowed to
accumulate on the underside of the car. This
extra weight can result in increased fuel
consumption and also contribute to corro-
sion.
o Travel lightly. Don't carry unnecessary
weight in your car. Weight reduces fuel
economy.
o Don't let the engine idle longer than neces-
sary. If you are waiting (and not in traffic),
turn off your engine and restart only when
you're ready to go.

17TRAILER OR VEHICLE TOWING
C190A02S-AAT
If you are considering towing with your car, you
should first check with your State's Department
of Motor Vehicles to determine their legal re-
quirements.
Since laws vary from State to State, the require-
ments for towing trailers, cars, other types of
vehicles, or apparatus may differ. Ask your
Hyundai dealer for further details before towing.
CAUTION:Do not do any towing with your car during
its first 1,200 miles (2,000 km) in order to
allow the engine to properly break in. Fail-
ure to heed this caution may result in seri-
ous engine or transaxle damage.
!
C190B01S-AAT
Trailer Hitches
Select the proper hitch and ball combination,
making sure that it's location is compatible with
that of the trailer or vehicle being towed.
Use a quality non-equalizing hitch which distrib-
utes the tongue load uniformly throughout the
chassis.
The hitch should be bolted securely to the car
and installed by a qualified technician. DO NOT
USE A HITCH DESIGNED FOR TEMPORARY
INSTALLATION AND NEVER USE ONE THAT
ATTACHES ONLY TO THE BUMPER.
C190C03S-AATTrailer Brakes
If your trailer is equipped with a braking system,
make sure it conforms to federal and/or local
regulations and that it is properly installed and
operating correctly.
NOTE:If you tow a trailer or vehicle, your car will
require more frequent maintenance due to
the additional load. See "Maintenance Un-
der Severe Usage Conditions" on page 5-6.
C190D01S-AAT
Safety Chains
Should the hitch connection between your car
and the trailer or vehicle you are towing fail, the
trailer or vehicle could wander dangerously
across other lanes of traffic and ultimately leave
the roadway. To eliminate this potentially dan-
gerous situation, safety chains, attached be-
tween your car and the trailer or towed vehicle,
are required in most states.
!CAUTION:o Never connect a trailer brake system
directly to the vehicle brake system.
o When towing a trailer on steep grades (in
excess of 12%) pay close attention to the
engine coolant temperature gauge to
ensure the engine does not overheat. If
the needle of the coolant temperature
gauge moves across the dial towards
"H" (HOT), pull over and stop as soon as
it is safe to do so, and allow the engine
to idle until it cools down. You may
proceed once the engine has cooled
sufficiently.

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.
