Auto Start/Stop function
The concept
The Auto Start/Stop function helps save fuel.
The system switches off the engine during a
stop, e.g., in a traffic congestion or at traffic
lights. The ignition remains switched on. The
engine starts again automatically for driving off.
Certain vehicle components may experience
additional wear as a result of this system.
Automatic mode
The Auto Start/Stop function is operational after
each engine start.
This function is activated at speeds faster than
about 3 mph, approx. 5 km/h.
Engine stop
The engine is switched off automatically during
a stop under the following conditions:
Automatic transmission:▷The selector lever is in transmission position
D.▷The brake pedal remains pressed while the
vehicle is stationary or the vehicle is held by
Automatic Hold.▷The driver's safety belt is buckled or the
driver's door is closed.
The air flow of the air conditioner is reduced
when the engine is switched off.
Displays in the instrument cluster The display indicates that the
Auto Start/Stop function is ready
for an automatic engine start.
The display indicates that the
conditions for an automatic en‐
gine stop have not been satisfied.
Note
The engine is not switched off automatically in
the following situations:▷External temperature too low.▷The external temperature is high and auto‐
matic climate control is running.▷The passenger compartment has not yet
been heated or cooled to the required level.▷The engine is not yet at operating tempera‐
ture.▷The wheels are at a sharp angle or the steer‐
ing wheel is being turned.▷After driving in reverse.▷Fogging of the windows when the automatic
climate control is switched on.▷The vehicle battery charge is very low.▷The engine compartment lid is unlocked.▷HDC is activated.▷The parking assistant is activated.▷Stop-and-go traffic.▷The transmission selector lever is in position
N or M/S.

activated engine starts up automatically in the
following situations:▷Excessive warming of the passenger com‐
partment when the cooling function is
switched on.▷The steering wheel is turned.▷Automatic transmission: the transmission
position is changed from D to N, R, or M/S.▷Automatic transmission: the transmission
position is changed from P to N, D, R, or M/
S.▷Fogging of the windows when the automatic
climate control is switched on.▷The vehicle battery charge is very low.▷Excessive cooling of the passenger com‐
partment when the heating is switched on.
Preventing an automatic engine stop
with automatic transmission
The concept
To make it possible to drive away very quickly,
such as at an intersection, the automatic engine
stop can be actively prevented.
Preventing an engine stop using the
brake pedal
The engine stop can be actively prevented
within one second after the vehicle comes to a
standstill.
▷Immediately after the vehicle comes to a
standstill, briefly press the brake pedal
forcefully.▷Then press the brake pedal with normal
braking force.Activating/deactivating the system

automatic engine stop
During an automatic engine stop, the vehicle
can be switched off permanently, e.g., when
leaving it.
1.Press the Start/Stop button. The ignition is
switched off. The Auto Start/Stop function
is deactivated.
Transmission position P is engaged auto‐
