Driving in detail: eDRIVE
Hints 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.◀
Cautiously remove your foot from the ac‐
celerator pedal
Cautiously remove your foot from the acceler‐
ator pedal because the braking effect of the
electric motor can be stronger than with a
combustion engine. Otherwise, abrupt braking
and slow-down may confuse other traffic.◀
Accelerator pedal positions1Deceleration2Coasting3Acceleration or constant speed: ePOWER
Deceleration
The deceleration depends on the position of
the accelerator pedal. The less the actuation of
the accelerator pedal, the greater the decelera‐
tion. In this way energy is recovered and the
high-voltage battery is charged.
Releasing the accelerator pedal causes decel‐
eration similar to cautious braking. Addition‐
ally, the brake lights will come on without hit‐
ting the brakes.
Energy recovery: CHARGE The high-voltage battery is recharged in part
through energy recovery. The electric motor
acts as a generator when decelerating and
converts the kinetic energy into electrical en‐
ergy.
Energy can be recovered if the following condi‐
tions are met:▷The vehicle is moving.▷Speed higher than approx.
12 mph/20 km/h.▷Selector lever position D or R is set.▷Gas pedal is not actuated or only pressed
down 1/3 of the way.
Energy cannot be recovered in the following
situations:
▷Selector lever position N is set.▷While drive stability control systems, e.g.
DTC, are active and control the vehicle,
even though this is not indicated by an in‐
dicator light.▷The high-voltage battery is fully charged.▷When temperature of the high-voltage bat‐
tery is very low or very high.
In winter it might be possible that the en‐
ergy recovery is temporarily unavailable af‐
ter startup.
Always be ready to apply the brake
Always be ready to apply the brake, be‐
cause without energy recovery there is also no
braking action through the electric drive unit.
The vehicle could roll further than anticipated.
This may constitute a danger for other traffic.◀
Exemplary traffic situations
If a deceleration operation is foreseeable while
driving, this can be used for energy recovery.

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.
Energy recovery In the event of danger, such as with locked
wheels, energy recovery is reduced in order to
prevent unstable driving situations.Always be ready to apply the brake
Always be ready to apply the brake, be‐
cause without energy recovery there is also no
braking action through the electric drive unit.
The vehicle could roll further than anticipated.
This may constitute a danger for other traffic.◀
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.
Note Adjust your driving style to the situation
An 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.◀Seite 107Driving stability control systemsControls107

Driving comfortVehicle 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.
Camera-based cruise control
with Stop & Go function, ACC
The concept Use this system to select a desired speed that
the vehicle will maintain automatically on clear
roads.
To the extent possible, the system automati‐
cally adjusts the speed to a slower vehicle
ahead of you.
A camera on the interior rear view mirror is
used to detect vehicles driving ahead.
The distance that the vehicle maintains to the
vehicle ahead of you can be varied.
For safety reasons, it depends on the speed.
To maintain a certain distance, the system au‐ tomatically reduces the speed, applies the
brakes lightly, or accelerates again if the vehi‐
cle ahead begins moving faster.
If the vehicle ahead of you brakes to a halt, and
then proceeds to drive again within a brief pe‐
riod, the system is able to detect this within the
given system limits. Your own vehicle will
brake automatically and then accelerate again.
If the vehicle ahead of you drives away again
after a prolonged period, briefly press the ac‐
celerator pedal or press the appropriate buttonto reactivate the system. The vehicle will auto‐
matically accelerate.
As soon as the road is clear, the vehicle accel‐
erates to the desired speed.
The speed is also maintained downhill, but
may not be maintained uphill if engine power is
insufficient.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.
Hints Personal responsibility
Even an active system holds the driver
responsible for his or her driving, particularly
for staying in your lane, adjusting your speed,
keeping your distance and for your driving
style all in relation to traffic.
Technically the system has its limits, it cannot
independently react to all traffic situations.
Monitor your driving, be on the alert, observe
the vehicle surroundings and other traffic and
react when needed, e.g. through braking,
steering or make evasive maneuvers - risk of
accident.◀
Unfavorable weather conditions
In the event of unfavorable weather and
light conditions, e. g. if there is rain, snowfall,
slush, fog or glare, this may result in poorer
recognition of vehicles as well as short-term
interruptions for vehicles that are already de‐
tected. Drive attentively, and react to the cur‐
rent traffic situation. Intervene actively when
necessary, e.g., by braking, steering or making
an evasive maneuver, otherwise, there is the
risk of an accident.◀Seite 110ControlsDriving comfort110

When you approach a curve the system may
briefly report vehicles in the next lane due to
the bend of the curve. If the system deceler‐
ates you may compensate it by briefly acceler‐
ating.
After releasing the gas pedal the system is re‐
activated and controls speed independently.
Driving away In some situations, the vehicle cannot drive off
automatically; for example:
▷On steep inclines.▷From behind bumps in the road.
In these cases, step on the accelerator pedal.
Malfunction
A Check Control message is displayed if the
system fails.
The system may not be fully functional in the
following situations:
▷When an object was not correctly de‐
tected.▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the camera viewing field or the front
windshield are dirty or covered.▷When driving toward bright lights.▷Up to 20 seconds after drive readiness is
switched on via the Start/Stop knob.▷During calibration of the camera immedi‐
ately after vehicle shipment.Cruise control
The concept The system maintains a preset speed via the
buttons on the steering wheel. The system
brakes on downhill gradients if engine braking
is insufficient.
General information
Depending on the driving settings, the features
of the cruise control can change in certain
areas.
Hints Unfavorable conditions
Do not use the system if unfavorable
conditions make it impossible to drive at a con‐
stant speed, e.g.:▷On winding roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
Otherwise, you could lose control of the vehi‐
cle and cause an accident.◀
