Automatic engine start-stop function (MSA)

When the vehicle is stopped, the engine will be switched off if the driver operates the brake with their foot. This function could be used for example when stopping at traffic lights or in traffic. When automatic engine start is used, quick and comfortable build-up of the power transmission is supported by the automatic transmission.

The automatic engine start-stop function (MSA) ensures that the engine is stopped only when this can be carried out without disadvantaging driver comfort or vehicle safety. When the vehicle is stopped, the engine therefore continues to run under the following preconditions:

• Engine not yet at operating temperature
• Temperature of passenger compartment not in target range
• Battery charge insufficient
• Steering wheel movements being made by driver
