Dual Automatic Climate Control
System
With this system you can control the heating, cooling,
and ventilation for your vehicle.
Automatic Operation
AUTO (Automatic): Turn both the fan and mode knob to
AUTO for automatic control of the inside temperature, the
air delivery mode and the fan speed. You may notice a
delay of two to three minutes before the fan comes on
when the automatic operation is used in cold weather.
For the automatic system to function, the temperature
must be set between 60°F (15°C) and 90°F (32°C).
1. Adjust the temperature to a comfortable setting.
2. Press the PASS button to turn the passenger
climate control system on and off. When the
passenger system is off, the driver’s temperature
setting is also used for the passenger and the
passenger display is off.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system will
start out blowing air at the floor but may change
modes automatically as the vehicle warms up
to maintain the chosen temperature setting. The
length of time needed for the air to warm up
will depend on the outside temperature and the
length of time that has elapsed since your vehicle
was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature,
if necessary.
Do not cover the solar sensor located in the center
of the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensors” later
in this section.
