What does the system do?
Start-stop can stop the combustion engine at a standstill and restart it when required. Battery condition, temperatures and other requirements affect activation.

Function, changes and requirements
What does the option mean?
The option concerns automatic stopping. Whether a supported solution disables it or remembers a state must be confirmed; memory behaviour is not assumed.
What do we check on your vehicle?
We check the original function and requested behaviour, separately from start authorisation, battery monitoring and the normal start button. The exact control unit, software version, fitted hardware and intended use determine the scope. A configurator entry does not replace this assessment.
Frequently asked questions
Does every vehicle support this function?
No. We check the vehicle, control unit and software against the actual supported function. Include existing faults and modifications. Transmission functions also require the exact gearbox version.
Does selecting an option approve its use?
No. Changes to emissions, noise or protection functions can affect legal use and operating safety. This page promises no road approval; diagnosis and a permissible repair are considered first.
