Intelligent Auto Start Stop
function
Depending on the equipment version and coun‐
try version, the vehicle has various sensors to re‐
cord the traffic situation. This enables the intelli‐
gent Auto Start Stop function to adapt to various
traffic situations and, where necessary, behave in
an anticipatory manner.
For example, in the following situations:
▷ If a situation is detected in which the duration
of the stop is likely to be very short, the en‐
gine is not stopped automatically. Depending
on the situation, a message is shown on the
Control Display.
▷ If a situation is detected in which the vehicle
should drive off immediately, the stopped en‐
gine is started automatically.
The function may be limited if the navigation data
is invalid, outdated or not available, for example.
