• Keep the exhaust pipe area clear
to help reduce the buildup of
exhaust gas under the vehicle.
• Check the drain tube of the fresh
air inlet for trapped water before
assuming that there is a leak in the
heating system.
Special Precautions
WARNING
Excessive heat may cause the pres-
surized components of the air condi-
tioning system to explode. Never weld,
solder, steam clean, or use a blow
torch near any part of the air condition-
ing system. Failure to comply may re-
sult in death, personal injury, equip-
ment or property damage.
WARNING
Air conditioning refrigerant can be haz-
ardous to your health. DO NOT ex-
pose yourself to leaking refrigerant for
prolonged periods near excessive
heat, open flames, or without proper
ventilation. Failure to do so may result
in death or personal injury.
If a refrigerant leak develops in the
presence of excessive heat or an open
flame, hazardous gases may be
generated. If you become aware of a
refrigerant leak on your vehicle have your
system serviced immediately and observe
the following precautions: Stay away from
the hot engine until the exhaust manifold
has cooled. Do not permit any open flame
in the area. Even a match or a cigarette
lighter may generate a hazardous quantity
of poisonous gas. Do not smoke in the
area. Inhaling gaseous refrigerant through
a cigarette may cause violent illness.
Heater
CAUTION
During extreme cold weather, DO NOT
blow hot defroster air onto cold wind-
shields. This could crack the glass.
Turn the Air Flow Control Dial to De-
frost and adjust the fan speed accord-
ingly while the engine warms. If the
engine is already warm, move the
Temperature Control Dial to "cool,"
then gradually increase the tempera-
ture when you see that the windshield
is starting to warm up. Failure to com-
ply may result in equipment damage.
• Check all heater controls for full-
range operation.
• Check hoses, connections, and
heater core for condition and leaks.
Air Conditioner
WARNING
The air conditioning system is under
pressure. If not handled properly dur-
ing servicing, it could explode. Any
servicing that requires depressurizing
and recharging the air conditioning
system must be conducted by a quali-
fied technician with the right facilities
to do the job. Failure to comply may
result in death, personal injury, equip-
ment or property damage.
