Operating readiness 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 operating readiness and any unnec‐
essary electronic systems/power consumers.
Operating readiness is switched off automati‐
cally in the following situations while the vehi‐
cle is stationary and the engine is off:▷When locking the vehicle, and when the
low beams are activated.▷Shortly before the battery is discharged
completely, so that drive readiness is
maintained. This function is only available
when the low beams are turned off.▷When opening or 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.
Selector lever position P is automatically en‐
gaged when operating readiness is switched
off. In order for the vehicle to be able to roll,
e.g. into a car wash, heed the information re‐
garding washing in automatic car washes, refer
to page 187.
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.
Selector lever position P is automatically en‐
gaged when drive readiness is switched off. In
order for the vehicle to be able to roll, e.g. into
a car wash, heed the information regarding
washing in automatic car washes, refer to
page 187.
Drive readiness in detail
The concept The following are the different drive readiness
variants:▷Electric drive readiness, Silent Start, refer
to page 63.
The vehicle is powered by the electric mo‐
tor.▷Starting the combustion engine, refer to
page 63.
The vehicle is powered by the combustion
engine.
Hints
Do not leave the vehicle unattended
Do not leave the vehicle unattended with
drive readiness active; otherwise, it may pose a
risk.◀
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 vehicle
due to missing engine noises. Please take spe‐
cial care when parking or leaving a parking
space.◀
Display on the Start/Stop buttonGeneral information Drive readiness is also displayed
through light indicators on the
Start/Stop button.
Lighting pulses orange
▷After unlocking and opening the door.▷After switching off drive readiness.
When the brake pedal is depressed, the light‐
ing becomes more intense.

Lighting lights up steady blue
After drive readiness is switched on, light turns
blue. The vehicle is ready to drive. The READY
indicator lights up in the instrument cluster. In
addition, a signal sounds.

Start or Start of the combustion engine.
Electric drive readiness, Silent Start
The vehicle is ready for driving without starting
the combustion engine.
Silent Start is possible if the requirements for
Electric driving, refer to page 64, are met.
Display READY indicates drive readi‐
ness.
Starting the combustion engine Enclosed areas
Do not let the engine run in enclosed
areas, since breathing in exhaust fumes may
lead to loss of consciousness and death. The
exhaust gases contain carbon monoxide, an
odorless and colorless but highly toxic gas.◀
Unattended vehicle
Do not leave the vehicle unattended with
engine running or drive readiness switched on;
otherwise, it may pose a risk.
Before leaving the vehicle, engage lever in po‐
sition P P, and set the parking brake; other‐
wise, the vehicle is not secured against rolling
away.◀
Repeated starting in quick succession
Avoid trying to start the vehicle repeat‐
edly and in quick succession. Otherwise, the
fuel is not burned or is inadequately burned,
posing a risk of overheating and damage to the
catalytic converter.◀
The combustion engine is started with Acti‐
vate drive, refer to page 63, readiness under
the following conditions:▷The temperature of the hybrid system is
too high.▷The charge level or temperature of the
high-voltage battery is too low.
Driving away
1.Activate drive readiness.2.Apply the brake and engage lever in posi‐
tion P D, SPORT or R.3.Release the parking brake.4.Drive away.
Deactivating drive readiness
After parking the vehicle, you may hear noises due to operation of the hybrid system, such as
for cooling of the high-voltage battery.
After stopping the vehicle:
1.Depress the brake pedal.2.Set the parking brake.3.Press the Start/Stop button.
The READY indicator goes out and a signal
sounds. In case of longer idle times, follow the
instructions in the Care chapter, refer to

Before driving into a car wash
So that the vehicle can roll into a car wash ob‐
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.
SAVE Battery, maintaining charging
state
Should it be necessary, e.g., to conserve the
electrical range for a later point in time on the
trip, the current charging state of the high-volt‐
age battery can be maintained with this func‐ tion.
The function is possible under the following
conditions:▷The fuel fill level is sufficient.▷Engaged selector lever position D▷Drive mode Auto eDrive

MAX eDRIVE
General information Max eDRIVE forces electric driv‐
ing.
With Max eDRIVE, a speed of
approx. 75 mph, approx.
120 km/h is possible.
In special situations, the speed limit can con‐
sciously be exceeded by applying the acceler‐
ator pedal beyond the full throttle point, kick‐
down. The combustion engine is automatically

mode.
Overview
Activating Max eDRIVE Press button.
▷LED lights up: max eDRIVE is activated.▷LED goes out: max eDRIVE is deactivated.
Acoustic pedestrian protection
Depending on the country-specific version, the
system generates a continuous driving noise
during electric driving up to approx.
20 mph/30 km/h.
A speaker system broadcasts the noise to the
surroundings.
As a result, other traffic participants, e.g. pe‐
destrians or cyclists, can better perceive the
vehicle.
Switching on/off
Depending on the country-specific version, the
system is automatically active after every driv‐
ing-off or the system can be set on the Control
Display.

engine: POWER
Depending on the operating state, the com‐
bustion engine is automatically switched on:▷Selector lever position Sport is set.▷Speed for electric driving is exceeded.▷The high-voltage battery has an insuffi‐
cient charge.▷High-voltage battery is completely
charged, e.g., when driving downhill.▷For improved traction, e.g., on slippery
roads.▷During intense accelerations or on inclines.▷System-related requirement for hybrid
components.▷Adapting to the course of the road when
destination guidance is activated.
When reducing speed, the combustion engine
is switched off when the conditions for electric
driving, refer to page 64, are met.
Assistance for the
combustion engine
Depending on the operating state, the electric
motor provides assistance with additional pro‐
pulsive power.
ASSIST
During normal vehicle operation, the electric
motor assists the combustion engine, depend‐
ing on the situation.
eBOOST Accelerating quickly, such as when passing,
requires the maximum available power from
the electric motor. To do this, apply extra force
to the accelerator pedal.

Shift paddles
The shift paddles on the steering wheel allow
you to shift gears quickly while keeping both
hands on the steering wheel.
The shift paddles can be used only when Driv‐
ing with the combustion engine, refer to
page 65.
If Auto eDrive, refer to page 64, is activated,
the combustion engine starts first.
