Operating tips
•
To reduce fog build up on the windshield during humid weather, place
the air flow selector in the
position.
•
To reduce humidity build up inside the vehicle: do not drive with the
system off or with recirculated air
engaged.
•
Under normal weather conditions, do not leave the air flow selector in
A/C and recirculated air
or with the system off when the
vehicle is parked. This allows the vehicle to “breathe” using the
outside air inlet vents.
•
To improve the A/C cool down, drive with the windows slightly open
for 2-3 minutes after start up or until the vehicle has been “aired out”.
•
During extreme high ambient temperatures when idling stationary for
extended periods of time in gear, it is recommended to run the A/C
with recirculation mode
selected, turn off the rear A/C unit, reduce
blower fan speed from the highest setting and put the vehicle’s
transmission into the P (Park) position to continue to receive cool air
from your A/C system.
•
For maximum cooling performance, (MAX A/C):
In AUTO: Press AUTO control and set to desired temperature.
In Manual Override: Press the
(panel), A/C, and recirculated
air
, set the temperature to 60°F (16°C) and the fan to the highest
blower setting.
•
Do not put objects under the front seats that will interfere with the
airflow to the back seats.
•
Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
To aid in side window defogging/demisting in cold weather:
1. Select
.
2. Select A/C.
3. Adjust the temperature control to maintain comfort.
4. Set the fan speed to the highest setting.
5. Direct the outer instrument panel vents towards the side windows.
To increase airflow to the outer instrument panel vents, close the vents
located in the middle of the instrument panel.
