Abstract
A control device is provided for a motor vehicle having an electronically controllable automatic transmission, an electronic transmission selector lever and an electronic control unit. The control unit, which may be the transmission control unit, has a car wash functional module such that, after activation of the car wash functional module, the following steps are permitted at least once and/or at least for a predefined limited time, in each case without activation of the brake pedal: shutting down of the engine in the transmission selector lever position “N”; a subsequent restart of the engine in the transmission selector lever position “N”; and a changeover from the transmission selector lever position “N” to “D”. The car wash functional module can be activated or deactivated by the driver at his discretion via a display operator control element.
