B740D01Y-AATOperation Tipso If the interior of the car is hot when you first
get in, open the windows for a few minutes
to expel the hot air.
o When you are using the air conditioning
system, keep all windows closed to keep hot
air out.
o When moving slowly, as in heavy traffic, shift
to a lower gear. This increases engine speed,
which in turn increases the speed of the air
conditioning compressor.
o On steep grades, turn the air conditioning off
to avoid the possibility of the engine over-
heating.
o During winter months or in periods when the
air conditioning is not used regularly, run the
air conditioning once every month for a few
minutes. This will help circulate the lubri-
cants and keep your system in peak oper-
ating condition.
!
CAUTION:
o Replace the filter every 12,000 miles
(20,000 km) or once a year.
If the car is being driven in severe condi-
tions such as dusty, rough roads, more
frequent air conditioner filter inspec-
tions and changes are required.
o When the air flow rate is decreased, it
must be checked at an authorized
Hyundai dealer.
o If your vehicle is not equipped with this
filter, it can be installed by your dealer.
Check with your dealer for details.

AIR CONDITIONING CARE
G140D02A-AATChecking the Compressor Drive BeltWhen the air conditioning is being used regu-
larly, 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 the belt is too
loose, have it adjusted by your Hyundai dealer.

G140A01A-AATKeeping the Condenser CleanThe 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.
G140B01A-AATChecking the Air Conditioning Opera-
tion1. 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.
!
G140C01A-AATLubricationTo 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.
