The owner's manual does not correctly specify the certain conditions under which the automatic parking function (Auto-P) operates.

Manufacturer remedy

TMC will notify owners, and a Mercedes Benz dealer will supplement the Operator's Manual with a correct description of the Auto-P function equipped in the vehicle. This recall began June 25, 2020. Owners may contact TMC customer service at 1-877-855-2867. TMC's number for this recall is RC000190.
