If you have a rear heater (without rear air conditioning),
the control switch is located on the instrument panel.
To increase and decrease the flow of heated air to the
rear floor vents, move the switch marked

The knob has three speed positions.
To increase the flow
of heated air, move the switch toward HIGH. To turn the

Air Conditioning Heating
Before using your vehicle’s air conditioning, open the
windows to clear the vehicle of hot air. This reduces the
time it takes for your vehicle to cool down. Then keep
your windows closed for the air conditioner to work at
its best.
You can use
MAX A/C with the temperature knob in the
blue area, when it’s really hot outside and you need to
cool the inside air quickly.
MAX A/C lets in only a little
air from
the outside.
If you first use
MAX A/C, you can then use A/C with
the temperature knob in the blue area, as soon as the
vehicle has cooled down,
so outside air will be going
through your vehicle.
If your vehicle has rear air conditioning, setting it on
LO may enhance front A/C performance by allowing
trapped refrigerant in rear lines
to circulate.
When the air conditioning, DEFROST
or BLEND is on,
you may notice
a slight increase or decrease in engine
speed, due to compressor operation. This
is normal
because the system is designed
to cycle the compressor
on and off to keep the desired temperature. On cold
days, use
HEATER with the temperature knob
in the red area. Outside air will be brought in through
the
floor outlets. The heater works best if you keep your
windows closed while using it.
If you use the optional engine coolant heater before
starting your engine, your heating system will produce
warmer air faster to heat the passenger compartment in
cold weather. See “Engine Coolant Heater” in the Index.
Ventilation Tips
Keep the hood and front air inlet free of ice, snow,
or any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of your windows.
When you enter a vehicle in cold weather, turn the
blower fan to
HI for a few moments before driving
off. This helps clear the intake ducts of snow and
moisture, and reduces the chance of fogging the
inside of your windows.
