Personal responsibility
The indicator and warning lamps do not
relieve the driver of the responsibility to adapt
his or her desired driving speed and style to the
traffic conditions.◀
Depending on how the vehicle is equip‐
ped, the indicator lamp in the instrument
cluster indicates whether the system is
switched on.

brakes until you actively assume control by
pressing on the brake pedal or accelerator.
The vehicle symbol flashes red and an
acoustic signal sounds:
You are requested to intervene by brak‐
ing or making an evasive maneuver.
System limits
Speed range
Best results are achieved when using the sys‐
tem on well-developed roads and highways.
The desired speed can be selected between
20 mph/30 km/h to 110 mph/180 km/h.
The system can also be activated when station‐
ary.
Comply with the legal speed limit in every situa‐
tion when using the system.Seite 108ControlsDriving comfort108

Switching the warning function on/off
Press the button
▷On: the LED lights up.▷Off: the LED goes out.
The state is stored for the remote control cur‐
rently in use.
Configuring the warning time
After the warning function is switched on, the
warning time can be set via the iDrive.
These settings have no effect on the time of the
warning from the Active Cruise Control that
prompts the driver to intervene or brake.
The selected channel is stored for the remote
control currently in use.
Display in the instrument cluster
The collision warning can be issued in the in‐
strument cluster, in the Head-up Display, and
acoustically.

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
The detection capacity of the radar sensor and
the collision warning has limitations.
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.▷Pedestrians.Seite 112ControlsDriving comfort112

Functional limitations
The system may not be fully functional in the
following situations:▷In heavy fog, rain, sprayed water or snowfall.▷In tight curves.▷If the radar sensor is dirty or covered.
Prewarning sensitivity
Depending on the set prewarning time, 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.▷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.◀

Things to remember when drivingVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
Breaking-in period
General information
Moving parts need to be broken in to adjust to
each other.
The following instructions will help achieve a
long vehicle life and good economy.
Engine and differential
Always obey the official speed limit.
Up to 1,200 miles/2,000 km
Do not exceed the maximum engine and road
speed:▷For gasoline engine, 4,500 rpm and
100 mph/160 km/h.
Avoid full-throttle operation and use of the
transmission's kickdown mode for the initial
miles.
From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac‐
tion potential until after an initial breaking-in pe‐
riod.
Drive conservatively for the first
200 miles/300 km.
Brake system
Brakes require an initial break-in period of ap‐
prox. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and discs. Drive moderately during this break-in
period.
Following part replacement
The same breaking in procedures should be ob‐
served if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
General driving notes
Closing the trunk lid Drive with the trunk lid closed
Only drive with the tailgate closed; other‐
wise, in the event of an accident or braking or
evasive maneuvers, passengers or other road
users may be injured or the vehicle may be dam‐
aged. In addition, exhaust fumes may enter the
passenger compartment.◀
If driving with the tailgate open cannot be
avoided:▷Close all windows and the glass sunroof.▷Greatly increase the blower speed.▷Drive moderately.
Hot exhaust system
Hot exhaust system
High temperatures are generated in the
exhaust system.
