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.
Active Cruise Control withStop & 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.
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 button
to 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.◀
Before leaving the vehicle, secure it
against moving on its own.
Before leaving the vehicle with the engine run‐
ning: set the parking brake and ensure that theSeite 124ControlsDriving comfort124

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.
Radar sensor
For US owners only
The transmitter and receiver units comply with
part 15 of the FCC/Federal Communication
Commission regulations. Operation is gov‐
erned by the following:
FCC ID:
▷OAYARS3-A
Compliance statement:
This device complies with part 15 of the FCC
Rules. Operation is subject to the following
two conditions:
▷This device may not cause harmful inter‐
ference, and▷this device must accept any interference
received, including interference that may
cause undesired operation.Any unauthorized modifications or changes to
these devices could void the user's authority to
operate this equipment.
Malfunction
The system cannot be activated if the radar sensor is not aligned correctly. This may be
caused by damage incurred during parking,
e.g.
A Check Control message is displayed if the
system fails.
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.◀

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 - risk of accident.◀
Changes to the parking space
Changes to the parking space after it was
measured are not taken into account by the system.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the risk of an acci‐
dent.◀
Transporting cargo
Cargo that extends beyond the perimeter
of the vehicle is not taken into account by the
system during the parking procedure.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the risk of an acci‐
dent.◀
Curbs
The parking assistant may steer the vehi‐
cle over or onto curb if need be.
Therefore, always be alert and ready to inter‐
vene; otherwise, the wheels, tires, or the vehi‐
cle may become damaged.◀
An engine that has been switched off by the
Auto Start Stop function is restarted automati‐
cally when the parking assistant is activated.
Requirements
For measuring parking spaces▷Maximum speed while driving forward ap‐
prox. 22 mph/35 km/h.▷Maximum distance to row of parked vehi‐
cles: 5 ft/1.5 m.
Suitable parking space
▷Gap between two objects with a minimum
length of approx. 5 ft/1.5 m.▷Min. length of gap between two objects:
your vehicle's length plus approx.
4 ft/1.2 m.▷Minimum depth: approx. 5 ft/1.5 m.
