If equipped, Adaptive Cruise Control may be used when towing an attached trailer that is electrically connected and within GM-approved allowable size and weight limits.
When you turn on Adaptive Cruise Control while trailering and change the gap settings, an icon will appear in your Driver Information Centre (DIC) next to your gap setting display that indicates you have trailering functionality for Adaptive Cruise Control equipped.
When towing a trailer, Adaptive Cruise Control driving characteristics, such as following gap, acceleration rates and braking rates, may be modified to provide a better towing experience.
When towing a trailer with Adaptive Cruise Control, it is important to properly set the Trailer Gain. Check your Owner’s Manual for more information on setting Trailer Gain.
It is recommended you select Tow/Haul mode when driving down steep hills or mountain grades, or when hauling heavy loads.
If you turn on Adaptive Cruise Control and do not see the TRAILERING icon in the DIC when you try to change your gap settings, your vehicle is not properly equipped to use Adaptive Cruise Control while trailering. If this is the case, do not use Adaptive Cruise Control while trailering.
Adaptive Cruise Control should not be used while towing a trailer with an aftermarket trailer brake controller. Aftermarket trailer brake controllers may not function properly with the Adaptive Cruise Control system.
You should read your Owner’s Manual to learn more about the limitations of the system.
