Start/stop button

Together with the remote key, the START-STOP button is used to start the vehicle. The remote key contains an authorization code for the relevant vehicle.

Two hall effect sensors are installed in the START-STOP button. The hall effect sensors detect whether the START-STOP button is operated. When the CAS detects an authorized remote key, terminal 30B is switched on. Pressing the start/stop button initializes the engine start. In the process, the CAS control unit checks the following prerequisites:

With automatic transmission, selector lever position "P" or "N" and brake control
With manual gearbox, clutch control

When all the prerequisites have been met, the engine is started by the CAS control unit in that terminal 50 to the starter motor is activated. To stop the engine, press the START-STOP button once again. The engine is switched off; terminal R remains switched on. On vehicles with automatic gearboxes, the engine can only be stopped with the vehicle at a standstill when the parking lock is engaged.

The START-STOP unit is connected via a 14-pin plug connection to the CAS control unit.

NOTE: Emergency function during driving.

For safety reasons, the engine can be stopped during driving by pressing the START-STOP button. A renewed start in this case is possible without additional brake control or clutch control.
