Check the battery terminals for
corrosion (a white or yellowish
powder). To remove it, cover the
terminals with a solution of baking
soda and water. It will bubble up and
turn brown. When this stops, wash it
of f with plain water. Dry of f the
battery with a cloth or paper towel.
Coat the terminals with grease to
help prevent f uture corrosion.
Check the battery condition by
looking at the test indicator window
on the battery.
The label on the battery explains the
test indicator’s colors. Battery posts,
terminals and related accessories
contain lead and lead compounds.

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.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
.)
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.
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.

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.
