Steering Wheel Controls
WARNING: This page is about a different car, the 2007 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.
The HVAC control module receives GMLAN messages from the radio interface that the driver has activated a steering wheel control switch. The steering wheel control buttons can be reconfigured to control the following functions:
- Fan speed increase
- Fan speed decrease
- Driver set temperature increase
- Driver set temperature decrease
In order to configure the steering wheel controls, refer to Radio/Audio System Description and Operation . The HVAC system interprets the fan and set temperature switches on the steering wheel as if the driver had activated the same switch function on the HVAC control module.
