›START STOP system The basic idea of the START-STOP system is to always turn the engine
off when it does not need to be running. This feature is particularly ad-
vantageous in city traffic, where this significantly reduces fuel con-
sumption and thereby also considerably reduces vehicle running
costs .
When stopping the vehicle, an automatic engine cut-off takes place,
the warning light appears in the instrument cluster.
When starting up, the automatic start procedure takes place again.
Automatic shutdown / startup on vehicles with manual
transmission
The engine is switched off as soon as the vehicle comes to a halt, the
shift lever is moved into neutral and the clutch pedal is released.
The engine is started as soon as the clutch pedal is depressed.
Automatic shutdown / startup on vehicles with automatic
transmission
The engine is switched off as soon as the vehicle comes to a halt and
the brake pedal is operated.
The motor is started as soon as the accelerator pedal is depressed or,
if the Auto Hold function is deactivated, when the brake pedal is re-
leased.
Functional prerequisites of the START-STOP system
So that an automatic engine shutdown takes place when stopping and
then an automatic start-up process during start-up, the following con-
ditions must be met.
The driver's door is closed.
The driver has fastened the seat belt.
The driving speed was higher than 4 km/h after the last stop.Other conditions cannot be influenced or detected, these are subject
to the state of various vehicle systems and weather conditions. For
this reason, the START-STOP system may react differently in situa-
tions which seem identical from the driver's perspective.
If the conditions for shutdown are not met when the vehicle stops,
then no engine shutdown takes place, the warning light appears in
the instrument cluster.
If, when an engine is in automatic shutdown, START-STOP system de-
tects that the engine running is essential (e.g. As in the event of an
overloaded vehicle battery), then a premature automatic startup takes
place.
Deactivation of the START-STOP system
The START-STOP system can be temporarily deactivated, by pressing
the button in the front centre console. After switching the ignition
off and on, re-activation of the START-STOP system always takes
place.
Special conditions
Under certain circumstances, the vehicle can react more slowly than
usual to sudden acceleration, e.g. If the accelerator pedal is depressed
at the time of the automatic engine shutdown.11

Some warning lights are displayed in colour or white, depending on the
type of display.
Depending on the importance, some warning lights illuminate together
with the warning light (danger) or
(warning)in the list with the
warning lights.
