STARTING AND OPERATING
ENGINE EXHAUST GAS CAUTION
(CARBON MONOXIDE)
CAUTION:-Do not breathe exhaust gas because it contains carbon monoxide, which by itself has no color crador. Carbon monoxide is a
dangerous gas. It can cause unconsciousness and can be lethal.
If at any time you think exhaust fumes are entering the vehicle, have the cause
determined and corrected as soon as possible. If you must drive under these conditions, drive only with ALL windows lully OPEN.
Protect against carbon monoxide entry into the vehicle body. The best way is
to keep the engine exhaust system,
vehicle body and body ventilation system
properly maintained. We recommend that the exhaust system and body be
inspected by a competent technician:
• each time the vehicle is raised for an oil change;
• whenever a change is noticed in the sound, of the exhaust system;
• whenever the exhaust system, underbody or rear of the vehicle is damaged
or becomes corroded.
See your Maintenance Schedule folder for parts requiring inspection.
To allow proper operation of your vehicle's ventilation system, keep the air inlet
grille in front of the windshield clear of snow, leaves or other obstructions at all
times.
DO NOT PARK WITH THE ENGINE RUNNING OR IDLE THIS VEHICLE FOR
MORE
THAN 10 MINUTES WITH THE VENTILATION SYSTEM CONTROL
SWITCH
IN THE "OFF" POSITION. EVEN WITH THE VENTILATION SYSTEM ON, RUNNING THE ENGINE WHILE PARKED OR STOPPED FOR LONGER
PERIODS OF TIME IS NOT
RECOMMENDED. ENTRY OF CARBON
MONOXIDE INTO THE CAR BODY IS POSSiBlE WITH A POORLY REPAIRED, DAMAGED, OR CORRODED EXHAUST SYSTEM OR BODY.
Do not run the engine in CONFINED areas (such as garages or next to a
building) any more than needed to move the vehicle. When the
vehicle has to
be stopped
in an UNCONFINED area with the engine running for any more
than a few minutes, take the following steps:
A. Adjust the heating or cooling system to force outside air into the vehicle as
follows:
1. On vehicles not equipped with air conditioning, set the fan to
intermediate or high speed and the upper control lever to any position.
2. On vehicles equipped with air conditioning, set the fan to an
intermediate or high speed and the upper control lever to any position
except
"OFF" or "MAX."
B. Keep the exhaust tailpipe area clear of snow and other material to help
reduce the buildup of exhaust gases under the vehicle. This is particularly
important when parked in blizzard conditions.

VENTILATION SYSTEM
Your vehicle has a flow through ventilation system that provides a supply of outside "ram" air into the vehicle ' when it is moving . When the vehicle is not in
motion you can get a steady flow of outside air into the car when the heater or
air conditioning blower is running.
With the side
windOws closed, the flow lIYough ventilation system provides
outside air flow into the front air inlet grilles, through the vehicle and out the
rear air exhaust valves. (See illustration .)

with a small amount delivered to the windshield (defroster outlets). The air
temperature
Is controlled by the TEMPERATURE LEVER while the air
quantity
is controlled by the FAN LEVER. This position is used for most winter driving.
• BLEND -- The AIR SELECTOR LEVER may be adjusted between HEATER
and DEFROST positions to obtain a variable distribution of air between the
floor air outlet and the windsh ield defroster air outlets.
• Side window defogger air outlets direct air to the side windows whenever
the fan is operating.
•
DEFROST - -In this poSition, most of the air is delivered to the windshield
(defroster outlets) with a small amount
to the floor air outlet.
The windshield defrosting and defogging system assists in providing
good visibility through designated areas of the windshield under most inclement
weather conditions . For immediate operation of the vehicle, the windshield
should be scraped clear.
Operate system for 30 seconds before switching to DEFROST . This will
remove humid air from the system
and minimize rapid fogging of the glass
which can occur if humid air Is blown onto a cOol windshield .
AIR CONOmONING SYSTEM
This system combines heating and cOOling capabilities for comfort in all weather conditions.
During some air conditioning operating conditions, slight increases and
decreases of engine speed/power may be noticed . This
should be considered
normal, as the system is designed to cycle the compressor
ON and OFF to
maintain desired cooling. The reduced compressor operation should
benef~ fuel economy.
Fan Lever
The fan lever (LO-HI) provides speed control of the blower fan in all Air
Selector Lever positions except
OFF.
Temperature Control Lever
The femperature control lever regulates the temperature of the air entering the passenger compartment in All Air Selector Lever positions .
Air Selector Lever
The air selector lever regulates air flow from the heater, defroster and air
conditioning outlets.

outlets . This position. with the temperature
lever in full COLD. is used for
maximum cooling under conditions of high temperature and humidity .
• NORM (AIR COND) --Outside air is conditioned as ~ passes through the
system and is discharged from the upper outlets. This position is used for most air conditioning situations.
• BI-LEVEL (AIR COND) --Outside air is conditioned and directed out the
upper outlets PLUS the heater outlet. This position provides comfort and
keeps the windshield clear under low fogging conditions .
• VENT (ECONOMY) --Outside air is discharged from the upper outlet s. This position is provided for cool to moderate weather operation when
refrigeration is not required. The refrigeration compressor is turned off.
Operating Information -The engine cooling fan is automatically engaged in all air conditioning modes and defrost mode (with high air conditioning pressure).

• DEFROST c_ Outs ide air is cond~ioned and delivered from the defroster
outlets w i1h a small amount from the heater outlet. This position is
recommended for conditions of severe fogging and icing
only.
Operating Tip
For satisfactory operation of the air conditioning system. windows should always be closed, except for the first two or three minutes to remove hot air if
the car has been closed. This provides a fast cool-down in normal air
conditioning mode.
ELECTRO-CLEAR REAR WINDOW DEFOGGER
The optional defogger consists of a heating element bonded to the inside
surface
of the rear glass . The unit is operated by a switch on the instrument panel and functions only in the ON position. When activated an indicator light
will illuminate.
