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 immediately.

AIR CONDITIONING CARE

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 effi-
ciency. When removing such accumulations,
brush or hose them away carefully to avoid
bending the cooling fans.

Checking the Air Conditioning Opera-
tion
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 refriger-
ant level may damage the compressor.

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.

When the air conditioning is being used regular-
ly, the compressor drive belt tension should be
checked at least once a month with the engine
turned off.
To check the drive belt tension, press down on
the belt halfway between the engine crankshaft
and compressor pulleys. Pressing with your
finger, you should not be able to deflect this belt
anymore than 1/3 of an inch. If you have the
instruments to check it, with a force of 22 lb.
(98N), the deflection should be 0.315 inches
(approx 8.0 mm). If the belt is too loose, have it
adjusted by your Hyundai dealer.
