DrivingVehicle features and options
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
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Start/Stop button, drive readiness
The concept The following ready states can
be attained by pressing the
Start/Stop button:▷Radio ready state on/off.▷Ignition on/off.▷Activating/deactivating drive readiness.
To activate drive readiness, press the brake
pedal.
Switching radio-ready state on/off
The radio-ready state is activated by pressing
the Start/Stop button in the following situa‐
tions:
▷When the engine is running.▷When drive readiness is activated.▷When the engine is switched off automati‐
cally using the Auto Start/Stop function
and the brake is not applied.
Some electronic systems/power consumers
remain ready for operation.
Radio ready state is switched off automatically:
▷After approx. 8 minutes.▷When the vehicle is locked using the cen‐
tral locking system.▷Shortly before the battery is discharged
completely, so that the engine can still be
started.
If the engine is switched off and the ignition is
switched on, the system automatically
switches to the radio-ready state if the lights
are turned off or, if correspondingly equipped,
the daytime running lights are activated.
Ignition on 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 offPress the Start/Stop button again without
stepping on the brake.
All indicator lights in the instrument cluster go
out.
To save battery power when the engine is off,
switch off the ignition and any unnecessary
electronic systems/power consumers.
Information When switching off the ignition, the selector
lever position P is selected automatically if the
selector lever position D or R is selected.
The ignition is switched off automatically in the
following situations while the vehicle is station‐
ary and the engine is off:
▷When locking the vehicle, and when the
low beams are activated.Seite 75DrivingControls75
Online Edition for Part no. 01 40 2 963 694 - VI/15
▷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 after
approx. 15 minutes of no use.
When the ignition is switched off automatically
by opening or closing the driver's door, un‐
buckling the driver's safety belt or by the auto‐
matic switching of the low beams to parking
lights, the radio-ready state remains active.
Drive readiness
When drive readiness is activated, the vehicle
is operational. Activated drive readiness is the
equivalent of a running engine in conventional
vehicles. Deactivated engine readiness is
equivalent to switching the ignition off.
Drive readiness in detail
The concept
The following are the different drive readiness
variants:
▷Electric drive readiness, Silent Start, refer
to page 77
The vehicle is powered by the electric mo‐
tor.▷Starting the combustion engine, refer to
page 77
The vehicle is powered by the combustion
engine.Information
WARNING
When driving in electric mode, pedes‐
trians and other traffic might pay less attention
to the vehicle due to missing engine noise.
There is risk of an accident. Adjust the driving
style to the traffic conditions. Watch traffic
closely and actively interfere in the respective
situations.◀
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.

move the vehicle and endanger themselves
and traffic, e.g. with the following actions:
▷Pressing the Start/Stop button.▷Releasing the parking brake.▷Opening and closing of doors or windows.▷Shifting the selector lever into neutral.▷Using vehicle equipment.
There is risk of accidents or injuries. Do not
