Pontiac 2005 Grand Prix - Manual (Page 136)

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 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.

fan speed and counterclockwise to decrease the fan
speed. Turning the fan knob cancels the automatic fan
operation and places the system in manual. Turn the

the passenger compartment air filter, if equipped, may
need to be replaced. See Passenger Compartment Air
Filter on page 3-33 for additional information.

controller completely off. Only the rear defog and heated
