Outlet Adjustment - Hummer H2 2009 Owner's Manual

Sensors
The solar sensor, located
in the defrost grille in the
middle of the instrument
panel, monitors the solar
heat. Do not cover the solar
sensor or the system will
not work properly.
The interior temperature
sensors located in the
headliner above the driver
side seat measures the
temperature of the
air inside the vehicle.
There is also an exterior temperature sensor located
behind the front grille. This sensor reads the outside
air temperature and helps maintain the temperature
inside the vehicle. Any cover on the front of the vehicle
could cause a false reading in the displayed temperature.
The climate control system uses the information from
these sensors to maintain your comfort setting by
adjusting the outlet temperature, fan speed, and the air
delivery mode. The system may also supply cooler air to
the side of the vehicle facing the sun. The recirculation
mode will also be used as needed to maintain cool outlet
temperatures.

Outlet Adjustment

The vehicle has adjustable air outlets that can control
the amount and direction of the airflow inside the vehicle.
Use the thumbwheels located beside the air outlets to
direct the airflow up and down. Use the thumbwheels
below the air outlets to direct the air left or right.
