Displays of the hybrid
system
Displays in the instrument cluster
The concept The following functions of the hybrid system
are displayed:▷High-voltage battery charge indicator, refer
to page 77.▷Max eDrive, refer to page 64▷Maintaining charging state, refer to
page 78.▷Electric driving: ePOWER, refer to
page 77.▷Acceleration boost: eBOOST, refer to
page 78.▷Energy recovery: CHARGE, refer to
page 78.▷Drive readiness: READY, refer to
page 77.
The display depends on the system's operat‐
ing condition.
High-voltage battery charge indicator
High voltage
Even if no fill level bars are displayed next
to the battery symbol, the high-voltage system
is still under high voltage.◀
The fill level bars indicate the available charg‐
ing state of the high-voltage battery when op‐
erating readiness and drive readiness are
switched on.
In addition, the range for electric driving is dis‐
played.
Drive readiness: READY READY indicates drive readi‐
ness. For further information,
please refer to Drive readiness
in detail, refer to page 62.
Electric driving: ePOWER
The inner narrow blue stripe, arrow 1, marks
the range for electric driving.
If a white mark is located in the range after the
stripe, arrow 2, the combustion engine is
switched on.
In COMFORT and ECO PRO driving mode, the
specified power of the electric motor and the
internal combustion engine is indicated by a
white mark, arrow 3.
In ECO PRO mode, the range for efficient driv‐
ing style is colored blue, arrow 4.
For further information, please refer to Electric
driving: eDRIVE, refer to page 64.

Energy recovery: CHARGE
The energy recovered is indicated in the COM‐
FORT and ECO PRO modes by four bars in the
CHARGE range. The high-voltage battery is
being charged. Depending on the available
output of the high-voltage battery, more or
less eBOOST could be recovered. If the high-
voltage battery is completely charged, no en‐
ergy can be recovered. The four bars are
grayed-out.
For further information, please refer to Energy
recovery CHARGE, refer to page 66.
Acceleration boost: eBOOST
Five bars indicate the available output of the
electric motor for the eBOOST, refer to
page 31, acceleration boost. Depending on the
available output of the high-voltage battery,
there could be more or less eBOOST available.
If the high-voltage battery is completely dis‐
charged, all five bars are grayed-out.
Maintaining charging state
In the Maintaining charging state mode, the
arrow indicates the charging state of the high-
voltage battery that should be conserved for a
later point in the trip.
▷Gray arrow: maintaining charging state
mode deactivated.▷Orange arrow: maintaining charging state
mode activated.
Activating/deactivating the Maintaining charg‐
ing state mode, refer to page 64.

in the monitored systems.
A Check Control message is displayed as a
combination of indicator or warning lights and
text messages in the instrument cluster and in
the Head-up Display.
In addition, an acoustic signal may sound and a text message may appear on the Control Dis‐
play.
Indicator/warning lights
General information
The indicator and warning lights in the instru‐
ment cluster can light up in a variety of combi‐

Driving stability control systemsVehicle features and optionsThis 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.
Antilock Brake System ABS ABS prevents locking of the wheels during
braking.
The vehicle contains its steering power even
during full brake applications, thus increasing
active safety.
ABS is ready when car is ready to drive.
Brake assistant When you apply the brakes rapidly, this system
automatically produces the greatest possible
braking force boost. It reduces the braking dis‐
tance to a minimum during emergency stop.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the emergency stop.
DSC Dynamic Stability Control
The concept DSC prevents traction loss in the power
wheels when driving off and accelerating.DSC also recognizes unstable vehicle condi‐
tions such as fishtailing or nose-diving. Within
the physical limits DSC helps to keep the vehi‐
cle on a steady course by reducing engine
speed and by applying brakes to the individual
wheels.
A change in the drive type, refer to page 32,
can be made to improve traction.
Note Adjust your driving style to the situationAn appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, not
even with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Do not deactivate DSC when driving with
roof load
Do not deactivate Dynamic Stability Control DSC when driving with roof load, e.g. roof-
mounted luggage rack.
Otherwise, driving safety is not given in driv‐
ing-critical situation due to the elevated center
of gravity.◀
