Run the air conditioning at least once
a week during the cold weather
months. Run it f or at least ten
minutes while you are driving at a
steady speed with the engine at
normal operating temperature. This
circulates the lubricating oil con-
tained in the ref rigerant.If the air conditioning does not get as
cold as before, have your dealer
check the system. Recharge the
system with Ref rigerant HFC-134a
(R-134a). (See Specif ications on page
.)
Your car’s air conditioning is a sealed
system. Any major maintenance,
such as recharging, should be done
by a qualif ied mechanic. You can do
a couple of things to make sure the
air conditioning works ef f iciently.
Periodically check the engine’s
radiator and air conditioning
condenser f or leaves, insects, and
dirt stuck to the f ront surf ace. These
block the air f low and reduce cooling
ef f iciency. Use a light spray f rom a
hose or a sof t brush to remove them. 334

Whenever you have the air conditioning
system serviced, make sure the service
f acility uses a ref rigerant recycling
system. This system captures the
ref rigerant f or reuse. Releasing
ref rigerant into the atmosphere can
damage the environment.
The condenser and radiator f ins bend
easily. Only use a low-pressure spray
or sof t-bristle brush to clean them.

Check the operation of your car’s
exterior lights at least once a month.
A burned out bulb can create an
unsaf e condition by reducing your
car’s visibility and the ability to
signal your intentions to other
drivers.

The low beam headlight bulbs are a
type of high voltage discharge tube.
High voltage can remain in the
circuit even with the light switch of f
and the key removed. Because of
this, you should not attempt to
examine or change a low beam
headlight bulb yourself . If a low
beam headlight bulb fails, take the

regularly carry heavy items in the
