Dual Automatic Climate Control System - Pontiac Grand Prix 2007 Owner's Manual

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.
