Air Conditioning System

Your car's air conditioning is a sealed system. Any major maintenance,such as recharging, should be done
by a qualified mechanic. You can do a couple of things to make sure the
air conditioning works efficiently.
Periodically check the engine's
radiator and air conditioning
condenser for leaves, insects, anddirt stuck to the front surface. These
block the air flow and reduce cooling efficiency. Use a light spray from a
hose or a soft brush to remove them.

The condenser and radiator fins bend
easily. Only use a low-pressure spray
or soft-bristle brush to clean them.
Run the air conditioning at least once
a week during the cold weather
months. Run it for at least ten
minutes while you are driving at asteady speed with the engine at
normal operating temperature. This
circulates the lubricating oil con-
tained in the refrigerant. If the air conditioning does not get as
cold as before, have your dealer
check the system. Recharge the
system with Refrigerant HFC-134a (R-134a). (See Specifications on page 302.)
Whenever you have the air conditioning
system serviced, make sure the service
facility uses a refrigerant recycling
system. This system captures the
refrigerant for reuse. Releasingrefrigerant into the atmosphere can
damage the environment.

AIR CONDITIONING CONDENSER

If Your Engine Won't Start

Turn the ignition switch to ON (II).
Turn on the headlights and check
their brightness. If the headlights
are very dim or don't light at all,
the battery is discharged. See

Jump Starting on page 280 .
Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the fuses. If
the fuses are OK, there is proba-
bly something wrong with the electrical circuit for the ignition
switch or starter motor. You will
need a qualified technician to
determine the problem. (See

Emergency Towing on page 296 .)
If the headlights dim noticeably or
go out when you try to start the engine, either the battery is dis-
charged or the connections are
corroded. Check the condition of
the battery and terminal connec-
tions (see page 236). You can
then try jump starting the car from a booster battery (see page 280).
The Starter Operates Normally In this case, the starter motor'sspeed sounds normal, or even faster
than normal, when you turn the ignition switch to START (III), but
the engine does not run. Are you using the proper starting
procedure? Refer to Starting the
Engine on page 181. Do you have fuel? Turn the
ignition switch to ON (II) for a
minute and watch the fuel gauge.
The low fuel level warning light may not be working, so you were
not reminded to fill the tank. There may be an electrical
problem, such as no power to the
fuel pump. Check all the fuses
(see page 292).

If you find nothing wrong, you will
need a qualified technician to find
the problem. See Emergency
Towing on page 296 .

Taking Care of the Unexpected

Low Oil Pressure Indicator

This indicator should light when the ignition switch is ON (II), and go outafter the engine starts. It should
never come on when the engine is
running. If it starts flashing, it
indicates that the oil pressure dropped very low for a moment, then
recovered. If the indicator stays on
with the engine running, it shows that the engine has lost oil pressureand serious engine damage is
possible. In either case, you should
take immediate action.
Running the engine with low oil
pressure can cause serious mechanical damage almost immediately. Turn offthe engine as soon as you can safely get
the car stopped.

1. Safely pull off the road and shut off the engine. Turn on the hazard
warning indicators.
2. Let the car sit for a minute. Open the hood and check the oil level
(see page 171). Although oil leveland oil pressure are not directly
connected, an engine that is very
low on oil can lose pressure during cornering and other driving

maneuvers.

3. If necessary, add oil to bring the level back to the full mark on thedipstick (see page 217 ). 4. Start the engine and watch the oil
pressure indicator. If the lightdoes not go out within ten seconds,
turn off the engine. There is a mechanical problem that needs to
be repaired before you can continue driving. (See Emergency
Towing on page 296 .)
