Air Conditioning

#
(Air Conditioner): Press this button on the climate
control panel to turn the air-conditioning system on
or off. When A/C is pressed, an indicator light to the right
of the button will come on to let you know that A/C is
active. The instrument brightness control may have to be
adjusted to the highest setting during the daytime in
order to see the indicator lamp.
On hot days during initial start-up, open the windows to
let hot inside air escape; then close them. This helps
to reduce the time it takes for your vehicle to cool down.
It also helps the system to operate more efficiently.
For quicker cool down on hot days, do the following:
1. Select the vent/outside air mode.
2. Select the recirculation mode.
3. Select the air conditioner.
4. Select the coolest temperature.
5. Select the highest fan speed.
Using these settings together for long periods of time
may cause the air inside your vehicle to become too dry.
To prevent this from happening, select the vent mode
once the interior of the vehicle is cooled.
The air-conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.
