DrivingVehicle features and op‐
tions
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and sys‐
tems. The respectively applicable country provi‐
sions must be observed when using the respec‐
tive features and systems.
Start/Stop button
The concept
Pressing the Start/Stop button
switches the ignition on or off
and starts the engine.
Steptronic transmission: the en‐
gine starts in selector lever posi‐
tion P or N with the brake pedal pressed when
you press the Start/Stop button.

clutch pedal pressed when the Start/Stop but‐
ton is pressed.
Ignition on
Manual transmission: press the Start/Stop but‐
ton without stepping on the clutch pedal.
Steptronic transmission: press the Start/Stop
button, and do not press on the brake pedal at
the same time.
All vehicle systems are ready for operation.
Most of the indicator and warning lights in the
instrument cluster light up for a varied length of
time.
To save battery power when the engine is off,
switch off the ignition and any unnecessary
electronic systems/power consumers.
Ignition off
Manual transmission: press the Start/Stop but‐
ton again without stepping on the clutch pedal.
Steptronic transmission: shift to selector lever
position P, press the Start/Stop button again
without stepping on the brake.
All indicator lights in the instrument cluster go

To save battery power when the engine is off,
switch off the ignition and any unnecessary
electronic systems/power consumers.
The ignition is switched off automatically in the
following situations while the vehicle is station‐
ary and the engine is off:
▷During locking, also with the low beams ac‐
tivated.
▷Shortly before the battery is discharged
completely, so that the engine can still be
started. This function is only available when
the low beams are turned off.
▷When opening and closing the driver door,
if the driver's safety belt is unbuckled and
the low beams are turned off.
▷While the driver's safety belt is unbuckled
with driver's door open and low beams off.
▷The low beams switch to parking lights af‐
ter approx. 15 minutes of no use.

Information
DANGER
If the exhaust pipe is blocked or ventila‐
tion is insufficient, harmful exhaust gases can
enter into the vehicle. The exhaust gases con‐
tain carbon monoxide, an odorless and color‐
less but highly toxic gas. In enclosed areas, ex‐
haust gases can also accumulate outside of the
vehicle. There is danger to life. Keep the ex‐
haust pipe free and ensure sufficient ventila‐
tion.◀
WARNING
An unsecured vehicle can put itself into
motion and roll away. There is risk of an acci‐
dent. Before exiting, secure the vehicle against
rolling.
In order to ensure that the vehicle is secured
against rolling away, observe the following:
▷Set the parking brake.▷On uphill grades or on a slope, turn the
front wheels in the direction of the curb.
▷On uphill grades or on a slope, also secure
the vehicle, for example with a wheel
chock.◀
CAUTION
In the case of repeated starting attempts
or repeated starting in quick succession, the
fuel is not burned or is inadequately burned.
The catalytic converter can overheat. There is
risk of property damage. Avoid repeated start‐
ing in quick succession.◀
