Remote Start and Personalization

WARNING: This page is about a different car, the 2008 Cadillac STS. However, it is still accessible from the selected car via links, so may be relevant.

If the remote start personalization feature for climate control is selected through radio, the HVAC control module will receive information that defines the current driver of the vehicle from the Ezkey module through GMLAN communication. This information shall be stored inside the HVAC control module memory. When a different key fob is selected, the HVAC control module will recall the appropriate driver settings. The full auto mode and previous set temp will be commanded if ambient air temperature is above 0°C (32°F). Defrost mode will be commanded when the ambient air temperature is below 0°C (32°F). Upon a battery reset, the HVAC control module shall also set the driver ID to Driver#1. The HVAC system will memorize the following system configurations for up to 2 unique drivers:

Driver set temperature
Passenger set temperature
Mode
Blower motor speed
A/C compressor request, auto ON or A/C OFF

If the remote start personalization feature for heated and vented seat control is selected through radio, if the inside air temperature is below 12°C (54°F) the heated seat will be commanded to high. If the inside air temperature is above 26°C (80°F) and the ambient air temperature is above 21°C (70°F) the vented seat will be commanded to high. When the HVAC control module is first turned On or key On, the last stored settings for the current driver will be activated, heat/vented seat control is carried over from remote start.
