control and audio systems offered with your vehicle. Be
sure to read about the particular systems supplied with
your vehicle.

Air Conditioning
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 perfor~nance 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.
Heating
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.
