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
air flow selector in the O (OFF) or (in cold weather) MAX A/C
position.
• Under normal weather conditions, do not leave the air flow selector in
MAX A/C or O (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 in
the MAX A/C position, 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.
