ately. In this case, please contact the man‐

Collision warning with
braking function
The concept
The system issues a two-phase warning of a
danger of collision at speeds above approx.
10 mph/15 km/h. The time of these warnings
may vary depending on the current driving sit‐
uation.
The collision warning is available even if cruise
control has been deactivated.
It responds to stationary or moving objects that
are within the detection range of the radar sys‐
tem.
When the vehicle is intentionally brought into
contact with a vehicle, the collision warning is
delayed to avoid false warnings.
Warning stages
Prewarning
This warning is issued, for example, when there
is the impending danger of a collision or the dis‐
tance to the vehicle ahead is too small.
Acute warning with braking function
Warning of the imminent danger of a collision
when the vehicle approaches another object at
a relatively high differential speed.
The acute warning prompts the driver to inter‐
vene and, if there is the danger of a collision, is
accompanied by a braking intervention.
The braking intervention is executed with lim‐
ited braking force and for a brief period only. The
intervention cannot bring the vehicle to a com‐
plete standstill.
The braking intervention is executed only if DSC
Dynamic Stability Control, refer to page 107, is
switched on.
Adapting your speed and driving style
The acute warning does not relieve the
driver of the responsibility to adapt his or her
driving speed and style to the traffic condi‐
tions.◀
The braking intervention can be interrupted by
pressing on the accelerator or by actively mov‐
ing the steering wheel.
When towing or tow-starting the vehicle, switch
off the collision warning with braking function to
prevent undesired interventions.
The braking function is deactivated if the DSC
Dynamic Stability Control or DTC Dynamic
Traction Control is deactivated.
Switching the warning function on/off
Press the button
▷On: the LED lights up.Seite 120ControlsDriving comfort120
Online Edition for Part no. 01 40 2 607 879 - 09 11 490
▷Off: the LED goes out.
The state is stored for the remote control cur‐
rently in use.
Configuring the prewarning
After the warning function is switched on, the
following can be set via the iDrive:
▷The prewarning can be switched on/off.▷The time of the prewarning can be set.
These settings have no effect on the time of the
warning from the Active Cruise Control that
prompts the driver to intervene or brake.
Display in the instrument cluster
The collision warning can be issued in the in‐
strument cluster, in the Head-up Display, and
acoustically.
Warning stages
SymbolMeasureThe vehicle lights up in red: prewarn‐
ing.
Increase distance.The vehicle flashes red and an
acoustic signal sounds: acute warn‐
ing.
You are requested to intervene by
braking or making an evasive maneu‐
ver.
Adapting your speed and driving style
The display does not relieve the driver of
the responsibility to adapt his or her driving
speed and style to the traffic conditions.◀
System limits Be alert
Due to system limitations, warnings may
be not be issued at all, or may be issued late or
improperly. Therefore, always be alert and ready
to intervene; otherwise, there is the danger of an
accident occurring.◀
Detection range
This may result in the warning not being issued
or being issued late.
For example, the following situations may not be
detected:▷Slow moving vehicles when you approach
them at high speed.▷Vehicles that suddenly swerve in front of you
or sharply decelerating vehicles.▷Vehicles with an unusual rear appearance.▷Two-wheeled vehicles ahead of you.
Functional limitations
The system may not be fully functional in the
following situations:
▷In heavy fog, rain, sprayed water or snowfall.▷In tight curves.
Prewarning sensitivity
Each time after the prewarning time is set, this
may result in increased false warnings.
Cruise control
The concept
The system is functional at speeds beginning at
approx. 20 mph/30 km/h.
It maintains the speed that was set using the
control elements on the steering wheel.
The system brakes on downhill gradients if en‐
gine braking action is insufficient.
Unfavorable conditions
Do not use the system if unfavorable con‐
ditions make it impossible to drive at a constant
speed, for instance:
▷On curvy roads.▷In heavy traffic.Seite 121Driving comfortControls121
Online Edition for Part no. 01 40 2 607 879 - 09 11 490
▷On slippery roads, in fog, snow or rain, or on
a loose road surface.
Otherwise, you could lose control of the vehicle
and cause an accident.◀
Controls
At a glance
Switching on Press the button on the steering wheel.
The marking in the speedometer is set to the
current speed.
Cruise control can be used.
Switching off Deactivated or interrupted system
If the system is deactivated or interrupted,
actively intervene by braking and, if necessary,
with evasive maneuvers; otherwise, there is the
danger of an accident occurring.◀
Press the button.
▷If active: press twice.▷If interrupted: press once.
The displays go out. The stored desired speed
is deleted.
Interrupting When active, press the button.
The system is automatically interrupted if:
▷The brakes are applied.▷The clutch pedal is depressed.▷Transmission position D is disengaged.▷DTC Dynamic Traction Control is activated
or DSC is deactivated.▷DSC is actively controlling stability.▷HDC is activated.Maintaining/storing the current speed
Press the rocker switch while the system is in‐
terrupted.
When the system is switched on, the current
speed is maintained and stored as the desired
speed.
It is displayed in the speedometer and briefly
displayed in the instrument cluster, Displays in
the speedometer, refer to page 123.
When cruise control is maintained or stored,
DSC Dynamic Stability Control is switched on, if
necessary.
Change, maintain speed
The rocker switch can be pressed while inter‐
rupted to maintain and store the current speed.
Adapting the desired speed
Adapt the desired speed to the road con‐
ditions and be ready to brake at all times; other‐
wise, there is the danger of an accident occur‐
ring.◀
Press the rocker switch up or down repeatedly
until the desired speed is set.

to display a precise image.
A film in the windshield prevents double images
from being displayed.
Therefore, have the special windshield replaced
by a service center only.
