• Clear snow and ice from the hood and air inlet in front of the windshield . This helps the heater and defroster work better and reduces the chance 01 fogging the inside 01 the windshield .
•
Run the blower on "HI" for a few moments belore driving off. This helps
clear the intake ducts of snow and moisture and reduces the chance of
logging on the inside
01 the windows.
• Always keep the front inlet grilles clear of obstructions (leaves, ice, snow ,
etc .) .
• Always keep the underseat air path clear of objeCts .
Lower Air Vents
Two control handles located beneath the center instrument panel open (pull)
and close (full in ) the lower "ram " air vents. The amount of air discharged at these lower ·outlets increases with vehicle speed. Maximum airflow can be
obtained by opening any of the .side door windows approximately six inches. If so equipped, the rear quarter swing-out windows will"optimize lower vent
performance and provide maximum airflow without opening a side door glass . In this condition, minimum air buffeting and road noise is incurred.
HEATER SYSTEM (NON-AIR CONOmONEO SYSTEM)
Fan lever
The fan lever (OFF-HI) provides speed control of the blower fan in all Air Selector Lever pOSitions.
Temperature Control lever
The temperature control lever regulates the temperature 01 the air entering the
passenger compartment in
"HEA TEA" and " DEF " Air Selector Lever
positions . Full right position (HOT ) provides maximum heat air and full left position (COLD) provides minimum heat (ambient air temperature) air.
AIR Selector lever
• VENT --In this position, ambient outside ventilation air is discharged from the upper air outlets . Air quantity is controlled by the FAN LEVER.
• BLEND --The AIR SELECTOR LEVER may be adjusted between VENT and HEATER to obtain a variable distribution of air between the upper air outlets and the floor air outlet.

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).
• HEATER (ECONOMY) --Outside air is delivered from the heater outlet with
a small amount from the defroster outlets and the side window . defogger outlets. This position is used for most winter driving. The air conditioning compressor is turned off.
• 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.
After the defogger has operated for a short time. the system will
automatically shut off. If further defrosting or defogging is desired . simply actuate the switch again.

Downloaded from www.Manualslib.com manuals search engine NOTICE: H you need to replace the fuel cap, use only a cap specified for your model. An incorrect fuel cap can result in a serious maHunction of the fuel system or emission control system. You can get a correct replacement cap from your dealer.
CATALYTIC CONVERTER
The catalytic converter is an emission control device added to the exhaust system to reduce exhaust gas pollutants. The converter contains
a ceramic material coated with noble metal catalysts. To prevent contamination
and loss of effectiveness of the catalysts. unleaded gasoline must be used.
Unleaded
gasoline also reduces spark plug fouling, exhaust system corrosion and engine oil deterioration. Leaded gasoline will also damage the oxygen
sensor
in the Computer Command Control system which could affect emission
control.
To help prevent damage:
1. Keep your engine properly maintained. Engine malfunctions involving the
electrical, carburetion, electronic fuel injection or ignition systems may
result in unusually high catalytic converter and exhaust system
temperatures which, under extreme malfunctioning conditions, may ignite
interior floor ·covering materials above the converter. Do not keep driving
your vehicle if you detect engine misfire, noticeable loss of
performance, or other unusual operating conditions. Instead, have it
serviced promptly. See the Maintenance Schedule folder for information on inspecting and maintaining the engine, exhaust system, and other
components.
2. Do not push or tow this vehicle to start it. This may result in unusually
high catalytic converter
and exhaust system temperatures which under
extreme conditions may ignite interior floor-covering material above the
converter.
Disregarding these instructions
could damage the catalytic converter, the vehicle, or nearby property and affect warranty coverage.
COMPUTER COMMAND CONTROL SYSTEM
Most vehicles sold in the United States (and some vehicles sold in Canada)
have the Computer Command Control system.
The Computer Command Control system monitors the exhaust stream with
an oxygen sensor. Based on sensor signals, the electronic control module adjusts
the air-fuel ratio
as needed. It is very important to use only unleaded
gasoline in vehicles equipped with the Computer Command Control system.
Leaded gasoline will damage the oxygen sensor,
and may affect emission
control.
"Check Engine" Light
Most vehicles sold in the United States (and some vehicles sold in Canada)
have the Computer Command Control system.
Vehicles
.with the Computer Command Control system, include a "CHECK
ENGINE" light
on the instrument panel designed to indicate the need for
system service. It will come on during engine starting to let you know the bulb
is working. (The
light will stay on a short time aiter the engine starts.) Have the
system repaired if the "CHECK ENGINE" light does not come on during engine
starting.
If the light comes on, either intermittently or continuously while driving,
service to the Computer Command Control system is required. Although in

Downloaded from www.Manualslib.com manuals search engine FUSES AND CIRCUIT BREAKERS
The wiring circuits in your vehicle are protected tram short circuits by a combination of fuses, circuit breakers. and fusible
thermal links in the wiring itsel!. This greatly reduces the hazard
of electrically caused fires in the automobile. For access to fuses, grasp the handle of the fuseblock (located under the left
hand side of the instrument panel) and pull the fuseblock
downward . Swing the bottom of the fuseblock back up until it
latches when access is no longer desired.
The headlight wiring is protected by a circuit breaker in the light
switch .
An electrical overload will cause the lights to go on and off, or in some cases to remain off .. If this happens, have your
headlight wiring checked right away. The windshield wiper motor is protected by a circuit breaker in addition to a fuse . If the motor
overheats, due to overloading caused
by heavy snow, etc., the
wiper will remain stopped until the motor cools; 8e sure to have the cause of the overloading corrected.
Also, circuit breakers in the fuseblock protect the power win· dows and other power accessories. When the current load is too heavy, the circuit breaker opens and closes intermittently,
protecting the circuit until the cause is found and eliminated.
