Park Assist Off

WARNING: This page is about a different car, the 2007 GMC Sierra and 2007 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.

The PARK ASSIST OFF message is displayed in the DIC when the object alarm system is disabled due to conditions that disable or inhibit the system. The red LED in the rear display, as well as, the telltale in the switch will be lit, notifying the driver the PARK ASSIST system is disabled. The object alarm module requests the DIC via the serial data circuit to display PARK ASSIST OFF when it detects that one of the following conditions is true:

Object alarm system disabled through DIC vehicle customization feature. Refer to the Owners Manual for more information.
Automatic Object induced disable feature such as towing a trailer, bicycle rack, hitch receiver still attached to the vehicle.
The park brake is not fully released.
An object is hanging out of the endgate.
The system receives vibrations from a large nearby vehicle or from a heavy equipment such as a jackhammer.

In the case of towing a trailer, the PARK ASSIST OFF message will continue to be displayed until the trailer hitch receiver is removed and the vehicle is driven forward above 24 km/h (15 mph).
