If your vehicle has an optional air cOnditioner , use the "Economy;' (" Vent" or
"Heater") position s whenever possible, The air conditioner compr essor is not on in these positions and the reduced engine load can improve fuel eco nomy.
Engine Maintenance
An engine that is properly maintained wjJl provide better fuel economy than .one
thai is not . One misfirin g spa rk plu g will cut fuel economy quite a bit , and will
make a difference in the amount of pollution _emitted fro m your vehicle .
Excess Weight
Fuel economy is related to the work the engine must do. The heavier the load,
the more fuel
it takes to run your vehicle. Keep weight to a minimum by taking o~t any luggage or cargo when it is not needed. .
Tire Inflation
Underinflation not only causes needLess wear of the tires, but can also waste fuel. It's a good idea to check tire pressures often and, for the best fuel econ omy, keep
your tires inflated to the highest
pr~suresshown on the Tire Placard on'the left
front doo r of your car.
Wheel Alignment
Improper toe alignment will cause the tires to roll at an angle, which will result
in faster tire wear.
It takes power to ove rcome this improper alignment which,
in tum, wastes fuel.

Two control handles lOCated beneath the steering column open and close the tower
air vents. To compliment this system there is a power upper vent in the instrument
panel which is operated from the heater
control. The amount of air coming from the lower cutlets ~epends -on vehicle speed and the upper outJet~ depend on fan
'poed.
HEATER SYSTEM
I" .. ill A. HI
The windshield defrosting and defogging system assists in providing good visibility through designated areas of the windshield under most inclement weather
Conditions. For immedia_te operation of the vehicle. the windshield should be scraped clear.
Adjust
TEMPERATURE lever as required to giv_c -the desired degree afheat. Full
down position provides'maximum heat.
Move the ·
controllever down to-Defroster when windshield defrosting is needed.
Full down position diverts most of the air (low to the defroster outlets. This control
lever may
be adjusted between Heater and Defroster to obtain a partial distribution
of air between the heater and defroster outlets or the heater and vent outlets.
Operate system for 30 seconds before switching to-DEF. This will remove humid
air from tht system and minimize rapid fogging of-the glass which can occur if humid air is blown onto a cool windshield.
ELECTRO-CLEAR REAR WINDOW DEFOGGER
The optional ,defogger may be turned on after the engine is running by.placing
the switch (on the instrument panel) in the ON position. Power is indicated by
agr~n light. After the defogger has operated for a short time. the system _will
automatically
shut ofT. If further defrosting or defogging is desired. simply actuate the switch again. .
_
The defogger will not function if the ignition is turned off.
Refrain from removing decals
or other material from the inside of rear window
with a
razor or other sharp instrument since this may damage the heating element.

Air Outlets
The twin barrel vertical type center outlets maybe rotated or vanes turned to direct
air flow in direction desired. The outlets at each end of the instrument panel-may
be rotated or vanes adjusted as desired.
AIR CONDITIONING SYSTEM
This system combines heating and cooling capabilities for comfort in all weather
conditions.
During some air conditioning operation 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 benefit fuel economy.

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. A small amount of air also flows from
the defroster outlets. This position provides comfort
and keeps the windshield
clear under low fogging conditions.
• VENT (ECONOMY)-- Outside air is discharged from the upper outlets. This
position is used in cool to moderate weather when refrigeration is not
required. The refrigeration compressor
is turned off.
• HEATER (ECONOMY) --Outside air is delivered from the heater outlet
with a small amount from the defroster outlets. This position is used for most
winter driving. The compressor
is turned off.
