Mode Buttons
OUTSIDE AIR: Press this button (the light
will glow) to send outside air into your vehicle.
Using this setting while trying to defrost or defog the
windows will help clear the vents of moisture. Press the
RECIRCULATION button (the light on the OUTSIDE
AIR button will go off) to limit outside air entering the
vehicle. When the LOWER, DEFOG or DEFROST
setting is selected, the system will automatically go to
OUTSIDE AIR mode.
RECIRCULATION: Press this button (the light
will glow) to limit the amount of outside air entering
your vehicle by recirculating much of the air inside your
vehicle. You may use this setting to limit odors entering
your vehicle. Press the OUTSIDE AIR button (the light
on the RECIRCULATION button will go off) to let
outside air circulate into the vehicle.
Operating the Heating/Ventilation/Air Conditioning
(HVAC) system in the RECIRCULATION mode
may cause fogging of the vehicle’s windows when the
weather is cold and damp. To clear the fog, switch the
HVAC system to either the DEFOG or DEFROST mode
and increase the fan speed. To avoid re
- fogging of the
windows, operate the HVAC system in the OUTSIDE
AIR mode.
Air Conditioning
On very hot days, your vehicle will cool down more
quickly and economically if you open the windows
long enough to let hot, inside air escape. For all
settings, adjust the temperature knob and fan speed
as desired.
To get maximum cooling or a quick cool - down on very
hot days, press the A/C and RECIRCULATION buttons
(the lights will glow) and move the temperature lever
down (toward the blue area). Adjust the mode knob to
direct the air to the desired location. This setting should
not be used for long periods of time because the air may
become too cold and dry. Push the A/C button again
(the light will go off) to turn off the air conditioning.
When the air conditioner compressor is on, you may
sometimes notice slight changes in your vehicle’s engine
performance and power. This is normal. The system is
designed to help fuel economy while it maintains the
desired cooling level.
The air conditioner removes moisture from the air, so
you may sometimes notice water dripping from under
your vehicle’s engine compartment when it is idling or
after it has been turned off. This is normal.
