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.▷Operating readiness 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.
Some electronic systems/power consumers
remain ready for operation.
The radio-ready state is switched off automati‐
cally:
▷After approx. 8 minutes.▷When the vehicle is locked using the cen‐
tral locking system.▷Shortly before the battery is discharged
completely, so that drive readiness is
maintained.
The radio-ready state remains active if, e.g.,
the operating readiness is automatically
switched off for the following reasons:
▷Opening or closing the driver's door.▷Unfastening of the driver's safety belt.▷When automatically switching from low
beams to parking lights.
Operating readiness on
The switched on operating readiness corre‐
sponds to the switched on ignition for conven‐
tional vehicles.
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 operating readiness and any unnec‐
essary electronic systems/power consumers.
Operating readiness is switched off automati‐
cally in the following situations:
▷When locking the vehicle, even if the low
beams are activated.▷Shortly before the battery is discharged
completely, so that drive readiness is
maintained.
Note
If the engine is switched off and operating
readiness is switched on, the system automati‐
cally switches to the radio-ready state when
the door is opened if the lights are turned off
or, if correspondingly equipped, the daytime
running lights are activated.

serve instructions for going into an automatic
car wash, refer to page 187.
Electric driving: ePOWER
Note Awareness of vehicle reduced when
driven in electric mode
When driving in electric mode, note that, due
to the lack of engine noise, pedestrians and
other traffic might pay less attention to the ve‐
hicle due to missing engine noises. Please
take special care when parking or leaving a
parking space.◀
General information
In ePOWER, the vehicle is driven exclusively
electrically. ePOWER works automatically.
Depending on the charging state of the high-
voltage battery, maximum speed and range
achieved can vary.
For electrical driving, certain Conditions, refer
to page 64, must be satisfied.
Displays of the hybrid system, refer to
page 77.
Requirements▷State of charge and temperature of the
high-voltage battery is sufficient.▷Selector lever position D or R engaged.▷The accelerator pedal is only slightly de‐
pressed.▷The possible maximum speed for electric
driving is not exceeded.▷The driver's door is closed.Auto eDRIVE
General information
With each starting operation, Auto eDRIVE is
activated using the Start/Stop button.
In Auto eDRIVE, the vehicle is driven in hybrid
mode corresponding to the various driving sit‐
uations, i.e. the drive combines combustion
engine and electric motor. The respectively
most effective drive type is preferred.

If Auto eDrive, refer to page 64, is activated,
the combustion engine starts first.
▷Shift up: briefly pull right shift paddle.▷Shift down: briefly pull left shift paddle.
Gears will only be shifted at appropriate engine
and road speeds, for example downshifting is
not possible if the engine speed is too high.
The selected gear is briefly displayed in the in‐
strument cluster, followed by the current gear.
If the shift paddles on the steering wheel are
used to shift gears in automatic mode, the
transmission temporarily switches to manual
mode.
In the manual mode, if there has been no ac‐
celeration or shifting of the shift paddles within
a certain amount of time, the transmission
switches back to automatic mode.
