Air Condioning
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 counterclockwise.
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
counterclockwise.
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.
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.
