Air Conditioning (If Equipped)
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
For quick cool-down on very hot days, use MAX A/C
with
the temperature knob turned to the left. This setting
should be used to keep odors and/or dust from entering
the vehicle. For normal cooling on hot days, use A/C
with the temperature knob turned to the left.
On cool but sunny days, use
BI-LEVEL A/C to
deliver
warm air to the floor and cooler air to the instrument
panel outlets.
If you have the "VORTEC
4300" engine, when the air
conditioner is on, you may sometimes notice slight
changes in your vehicle's engine speed and power. This
is normal because the system is designed to cycle the
compressor on and off to keep the desired temperature.
Heating
The heater works best if you keep your windows closed
while using
it.
On cold days, use HEATER with the
temperature knob turned to the right. BLEND is useful
in cool weather when you have fog or ice on the
windshield or side windows.
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.
