What is this part and why does it matter?

This button disables the engine start-stop system, which automatically switches the engine off at idle (e.g. at traffic lights) and restarts it when needed, if the driver prefers the engine to keep running continuously.

Frequently asked questions

Some drivers prefer the engine to keep running continuously for consistent air conditioning, in very short stop-start traffic where cycling is excessive, or simply personal preference — this button gives that choice each drive.
