2004 Hyundai Elantra air condition

4CORROSION PREVENTION AND APPEARANCE CARE
3WASHING AND WAXING
o When cleaning lower door panels, rocker
panels and frame members, be sure that
drain holes are kept open so that moisture
can escape and not be trapped inside to ac-
celerate corrosion.E020E01A-AAT
Don't Neglect the Interior
Moisture can collect under the floor mats and
carpeting to cause corrosion. Check under the
mats periodically to be sure the carpeting is dry.
Use particular care if you carry fertilizers, clean-
ing materials or chemicals in the car.
These should be carried only in proper contain-
ers and any spills or leaks should be cleaned up,
flushed with clear water and thoroughly dried.
E020D01A-AATKeep Paint and Trim in Good Condition
Scratches or chips in the finish should be
covered with "touch-up" paint as soon as pos-
sible to reduce the possibility of corrosion. If
bare metal is showing through, the attention of
a qualified body and paint shop is recommended.
E020C01A-AATKeep Your Garage Dry
Don't park your car in a damp, poorly ventilated
garage. This creates a favorable environment
for corrosion. This is particularly true if you
wash your car in the garage or drive it into the
garage when it is still wet or covered with snow,
ice or mud. Even a heated garage can contrib-
ute to corrosion unless it is well ventilated so
moisture is dispersed.
E030A01A-AAT
Washing Your Hyundai
Never wash your car when the surface is hot
from being in the sun. Always wash your car in
the shade.
Wash your car frequently. Dirt is abrasive and
can scratch the paint if it is not removed. Air
pollution or acid rain may damage the paint and
trim through chemical action if pollutants are
allowed to remain in contact with the surface. If
you live near the ocean or in an area where road
salts or dust control chemicals are used, you
should pay particular attention to the underside
of the car. Start by rinsing the car to remove dust
and loose dirt. In winter, or if you have driven
through mud or muddy water, be sure to thor-
oughly clean the underside as well. Use a hard
direct stream of water to remove accumulations
of mud or corrosive materials. Use a good
quality car-washing solution and follow the
manufacturer's directions on the package.
These are available at your Hyundai dealer or
auto parts outlet. Don't use strong household
detergents, gasoline, strong solvents or abra-
sive cleaning powders as these may damage
the finish.
Use a clean sponge or cloth, rinse it frequently
and don't damage the finish by rubbing too hard.
For stubborn spots, dampen them frequently
and remove them a little at a time.

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.

17AIR CONDITIONING CARE
G140A01A-AAT
Keeping the Condenser Clean
The air conditioning condenser (and engine
radiator) should be checked periodically for
accumulation of dirt, dead insects, leaves, etc.
These can interfere with maximum cooling ef-
ficiency. When removing such accumulations,
brush or hose them away carefully to avoid
bending the cooling fans.
!
G140C01A-AAT
Lubrication
To lubricate the compressor and the seals in the
system, the air conditioning should be run for at
least 10 minutes each week. This is particularly
important during cool weather when the air
conditioning system is not otherwise in use.
G140B01A-AAT
Checking the Air Conditioning
Operation
1. Start the engine and let it run at a fast idle for
several minutes with the air conditioning set
at the maximum cold setting.
2. If the air coming out of the in-dash vents is
not cold, have the air conditioning system
inspected by your Hyundai dealer.
CAUTION:Running the air conditioning system for
extended periods of time with a low refrig-
erant level may damage the compressor.!
G130B02A-AAT
To Replace the Fluid
Recommended brake fluid conforming to DOT
3 or DOT 4 specification should be used. The
reservoir cap must be fully tightened to avoid
contamination from foreign matter or moisture.
NOTE:Do not allow any other liquids to contami-
nate the brake fluid. Seal damage will result.
WARNING:Use caution when handling brake fluid. It
can damage your vision if you get it in your
eyes. It will also damage your vehicle's
paint if spilled on it and not removed imme-
diately.
