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.

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.
▷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.

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.◀

DSC OFF button
Indicator/warning lights The indicator lamp flashes: DSC con‐
trols the drive and braking forces.
The indicator lamp lights up: DSC has
failed.
Deactivating DSC: DSC OFF Automatic switching of the drive type
Depending on the operating state of the
high-voltage system, the drive of the vehicle
automatically switches between front-wheel,
rear-wheel and four-wheel drive.
If DSC is deactivated, this may result in auto‐
matic change of the drive type for unstable driving situations.
To increase vehicle stability, activate DSC
again as soon as possible.◀
When DSC is deactivated, driving stability is
reduced during acceleration and when driving
in curves.
To increase vehicle stability, activate DSC
again as soon as possible.
Deactivating DSC Press and hold this button but not lon‐
ger than approx. 10 seconds, until the
indicator lamp for DSC OFF lights up in the in‐
strument cluster and displays DSC OFF.
The DSC system is switched off.
The steering and, depending on the equip‐
ment, suspension are tuned for sporty driving.
Activating DSC Press button.
DSC OFF and the DSC OFF indicator
lamp go out.Indicator/warning lights
When DSC is deactivated, DSC OFF is dis‐
played in the instrument cluster.
The indicator lamp lights up: DSC is
deactivated.
Automatic activation When DSC is deactivated, automatic activation
occurs in the following situations:▷The high-voltage battery has an insuffi‐
cient charge.▷The vehicle has a flat tire.▷When activating cruise control in TRAC‐
TION or DSC OFF mode.
DTC Dynamic Traction
Control
The concept The DTC system is a version of the DSC where
forward momentum is optimized.
The system ensures maximum headway on
special road conditions or loose road surfaces,
e.g., unplowed snowy roads, but with some‐
what limited driving stability.
Activating the Dynamic Traction Control DTC
provides maximum traction. Driving stability is
limited during acceleration and when driving in
curves.
Therefore drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
▷When driving in slush or on uncleared,
snow-covered roads.▷When freeing vehicle from deep snow or
driving off from loose grounds.▷When driving with snow chains.Seite 110ControlsDriving stability control systems110

TRACTION and the DSC OFF indica‐
tor lamp go out.
Performance Control Performance Control enhances the agility of
the vehicle.
To increase maneuverability, with a corre‐
spondingly sporty driving style, wheels are
braked individually. The resulting braking
power is simultaneously largely compensated
by an engine intervention.
Due to the variable drive configuration, this in‐
tervention can be done either on the front axle,
the rear axle or on both axles simultaneously.
Driving Dynamics Control The conceptThe Driving Dynamics Control helps to fine-
tune the vehicle's settings and features. Vari‐
ous programs can be selected for this purpose.
Note
Pressing the Driving Dynamics Control deacti‐
vates the Sport program, refer to page 72, of
the vehicle. The selector lever automatically
switches out of the Sport program in selector
lever position D. Use the Driving DynamicsControl to select the COMFORT or ECO PRO
programs.
