continued.
The "Start/Stop" symbol
in the instrument cluster goes out and
the time and temperature appear
(see "Display concept").
Conditions of an automatic engine stop
The Auto Start Stop function only stops or starts the engine if certain conditions are met.
Engine stop
The engine is switched off if:
-
The vehicle is stationary (speed <3 km/h)
-
The vehicle has been driven at > 5 km/h since the engine was last stopped
-
The vehicle has been driven at 5 km/h since the last change at terminal 15
-
The gearbox is in neutral
-
The clutch pedal is not pressed and the steering wheel not turned
-
The engine is virtually at idle speed.
Engine start (with action by the driver)
The engine can be restarted by the driver with the aid of the Auto Start Stop function if the
driver actively intervenes by pressing the clutch pedal down fully (or pressing the START-
STOP button).
Following this action by the driver, the engine will only start if the gearbox or transmission is
in neutral and the powertrain is not engaged.
Engine start (without action by the driver)
It may be necessary to start the engine without any active intervention by the driver.
(See also "Switch-on prompts")
The engine starts without any action on the driver's part if:
-
The vehicle starts to roll (forwards or backwards).
-
The brake pressure falls below a defined threshold value.
-
The battery charge falls below a particular threshold value.
-
The condensation sensor detects condensation on the windscreen (IHKA).
-
With the air conditioning compressor switched on, the evaporator temperature rises
above a particular threshold value.
Note:
The aforementioned criteria apply only for the Auto Start Stop function, in other
words not if the engine has been switched off at the SST (START-STOP button).
