1.Apply the brakes until the vehicle comes to
a stop.2.Press the Start/Stop button.
The engine is switched off.
The radio-ready state is switched on.3.Set the parking brake.
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 traffic congestion or at traffic lights. The ignition remains switched on. The
engine starts again automatically for driving
off.
Semi-automatic mode After every start of the engine using the Start/
Stop button, the Auto Start/Stop function is in
the last selected state, refer to page 72.
When the Auto Start/Stop function is active, it
is available when the vehicle is traveling faster
than about 3 mph, approx. 5 km/h.
Engine stop The engine is switched off automatically dur‐
ing a stop under the following conditions:
▷The selector lever is in selector lever posi‐
tion 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 from 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 met.
Functional limitations 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 car's interior has not yet been heated
or cooled to the required level.▷The engine is not yet at operating temper‐
ature.▷The wheels are at a sharp angle or the
steering wheel is being turned.▷After driving in reverse.▷Fogging of the windows when the auto‐
matic climate control is switched on.▷Vehicle battery is heavily discharged.▷At higher elevations.▷The engine compartment lid is unlocked.▷HDC Hill Descent Control is activated.Seite 71DrivingControls71

▷The parking assistant is activated.▷Stop-and-go traffic.▷Use of fuel with high ethanol content.
Starting the engineThe engine starts automatically under the fol‐
lowing conditions:
▷By releasing the brake pedal.
When Automatic Hold is activated: press
the accelerator pedal.
After the engine starts, accelerate as usual.
Safety mode
After the engine switches off automatically, it
will not start again automatically if any one of
the following conditions are met:
▷The driver's safety belt is unbuckled and
the driver's door is open.▷The hood was unlocked.
Some indicator lights light up for a varied
length of time.
The engine can only be started via the Start/
Stop button.
Functional limitations
Even if driving off was not intended, the deacti‐
vated engine starts up automatically in the fol‐
lowing situations:
▷Excessive warming of the car's interior
when the cooling function is switched on.▷The steering wheel is turned.▷Change from selector lever position D to N,
R or D/S.▷The accelerator and the brake are pressed
at the same time.▷Fogging of the windows when the auto‐
matic climate control is switched on.▷Vehicle battery is heavily discharged.▷Excessive cooling of the car's interior when
the heating is switched on.Preventing automatic engine stop
The concept To make it possible to drive off very quickly,
such as at an intersection, the automatic en‐
gine 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.
