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.
Active 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.
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.
Information WARNING
The system does not relieve from the
personal responsibility to correctly assess the
traffic situation. Based on the limits of the sys‐
tem, it cannot independently react to all traffic
situations. There is risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic closely and actively interfere in the re‐
spective situations.◀
WARNING
An unsecured vehicle can put itself into
motion and roll away. There is risk of an acci‐
dent. Before exiting, secure the vehicle against
rolling.
In order to ensure that the vehicle is secured
against rolling away, observe the following:▷Set the parking brake.▷On uphill grades or on a slope, turn the
front wheels in the direction of the curb.▷On uphill grades or on a slope, also secure
the vehicle, e.g. with a wheel chock.◀Seite 146ControlsDriving comfort146

ton or rocker switch.
Indicator/warning lights
Symbol lights up orange:
A vehicle has been detected ahead of
you.
Symbol flashes orange:
The conditions are not adequate for
the system to work.
The system was deactivated but applies the
brakes until you actively resume control by
pressing on the brake pedal or accelerator
pedal.
Symbol flashes red and a signal
sounds:
You are requested to intervene by
braking or make an evasive maneuver.
Displays in the Head-up Display Some system information can also be dis‐
played in the Head-up Display.
Distance information The symbol is displayed when the dis‐
tance from the vehicle traveling ahead
is too short.
The distance information is active under the
following circumstances:▷Active Cruise Control switched off.▷Display in the Head-up Display selected,
refer to page 105.▷Distance too short.▷Speed greater than approx.
40 mph/70 km/h.
System limits
Speed range The system is best used on well-constructedroads.
The minimum speed that can be set is
20 mph/30 km/h. The maximum speed that
can be set depends on the vehicle.
The system can also be activated when sta‐

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.
Weather
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 recogni‐
tion of vehicles as well as short-term interrup‐
tions for vehicles that are already detected. Drive attentively, and react to the current trafficsituation. If necessary, intervene actively, e.g.
by braking, steering or evading.
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.
The function for detecting and responding
when approaching stationary vehicles may be limited in the following situations:
▷During calibration of the camera immedi‐
ately after vehicle delivery.▷If the camera is malfunctioning or dirty. A
Check Control message is displayed.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.
Information WARNING
The use of the system can lead to an in‐
creased risk of accidents in the following situa‐
tions:▷On winding roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
There is risk of accidents or risk of property
damage. Only use the system if driving at con‐
stant speed is possible.◀
