Cadillac 2008 STS Automobile User Manual


 
Under some conditions, the air quality sensor system
does not operate. In cold weather, the system might
not be active (even if AUTO is displayed) because
of concerns of fogging your windows, which may occur
by activating recirculation mode. Also, the air quality
sensor system does not remain in recirculation mode
for extended periods of time that could cause stuffy
or very dry conditions in the vehicle. Following a poorly
running vehicle for an extended period of time may
not keep recirculation active indefinitely.
The air quality sensor does not activate due to organic
odors, like skunk, and may not activate on many
chemical-related odors. If you wish to limit these types
of odors, manually select recirculation. Your vehicle
could also have a charcoal filter that can limit many
odors from being pulled into your vehicle. This
filter needs to be changed periodically. See Scheduled
Maintenance on page 6-4. The air quality sensor
system does not protect against carbon monoxide (CO),
which you cannot see or smell. See Engine Exhaust
on page 2-38.

Turning the passenger’s side power button off will not
shut off the climate control system for the passenger.
