up dimly.
Before you change lanes after setting the turn
signal, the system issues a warning in the sit‐
uations described above.
The lamp in the housing of the exterior mirror
flashes and the steering wheel vibrates.
Hints Personal responsibility
The system does not serve as a substi‐
tute for the driver's personal judgment of the
traffic situation.
Be aware of the traffic situation and the vehi‐
cle's surroundings at all times, otherwise an
accident is still possible despite all warnings.◀

Driving comfortVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
Active Cruise Control with Stop & Go function, ACC
The conceptThis system can be used to select a desired
speed that the vehicle will maintain automati‐
cally 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, the
system is able to detect this within the given
system limits. If the vehicle ahead of your
drives away again from a halt, your vehicle is
able to accelerate if operated accordingly.
Even if some time passes before the vehicle
ahead of you drives away again, your own vehi‐
cle can still be accelerated automatically and
simply.
As soon as the road is clear, it accelerates to
the desired speed.The speed is also maintained on downhill gra‐
dients, but may not be maintained on uphill
slopes if engine power is insufficient.
General information
Depending on the set driving program, the
characteristics of the cruise control can
change in certain areas.
Hints Personal responsibility
Even an active system does not release
the driver from personal responsibility for the
driving process, especially for lane tracking,
adaptation of speed, distance and driving style
to the traffic conditions.
Because of technical system limits, the system
cannot independently react appropriately in all
traffic situations.
Monitor the driving process, the surrounding
area and what is occurring in traffic continu‐
ously and attentively and actively intervene as
required, e.g., by braking, steering or making an evasive maneuver.◀
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 events. Intervene actively when
necessary, e.g., by braking, steering or making
an evasive maneuver, otherwise, there is dan‐
ger of an accident.◀Seite 119Driving comfortControls119
Online Edition for Part no. 01 40 2 925 743 - II/14
Comply with the legal speed limit in every sit‐
uation when using the system.
Detection range
The detection capacity of the system and the
automatic braking capacity are limited.
Two-wheeled vehicles driving ahead of you
for instance might not be detected.
Limited detection capacity
Because of the limits to the detection ca‐
pacity, you should be alert at all times so that
you can intervene if necessary; otherwise,
there is the danger of an accident occurring.◀
Deceleration
The system does not decelerate when a sta‐
tionary obstacle is located in the same lane,
e.g., a vehicle at a red traffic light or at the end
of traffic congestion.
The system also does not respond to:
▷Pedestrians or similar slow-moving road
users.▷Red traffic lights.▷Stationary objects.▷Cross traffic.▷Oncoming traffic.
No warnings
A warning may not be issued when ap‐
proaching a stationary or very slow-moving ob‐
stacle. You must react yourself; otherwise,
there is the danger of an accident occurring.◀
Swerving vehicles
A vehicle driving in front of you is not detected
until it is completely within the same lane as
your vehicle.
Swerving vehicles
If a vehicle driving ahead of you suddenly
swerves into your lane, the system may not be
able to automatically restore the selected dis‐
tance. This also applies to major speed differ‐
ences to vehicles driving ahead of you, e.g.,
when rapidly approaching a truck. When a ve‐
hicle driving ahead of you is reliably detected,
the system requests that the driver intervene
by braking and carrying out evasive maneu‐
vers, if necessary. You must react yourself;
otherwise, there is the danger of an accident
occurring.◀
Unexpected lane change
If a vehicle ahead of you unexpectedly moves
into another lane from behind a stopped vehi‐
cle, you yourself must react, as the system
does not react to stopped vehicles.

rior rearview mirror buttons.
Special feature of the alternating-
code wireless system
If you are unable to operate the system after
repeated programming, please check if the
system to be controlled features an alternat‐
ing-code system.
Read the system's operating manual, or press
the programmed button on the interior rear‐
view mirror longer. If the LED on the interior
rearview mirror starts flashing rapidly and then
stays lit constantly for 2 seconds, the system
features an alternating-code system. Flashing
and continuous illumination of the LED will re‐
peat for approximately 20 seconds.
For systems with an alternating-code system,
the universal garage door opener and the sys‐
tem also have to be synchronized.
Please read the operating manual of the sys‐
tem being set up for information on how to
synchronize the system.

Danger of burns
Only change bulbs when they are cool;
otherwise, there is the danger of getting
burned.◀
Working on the lighting system
When working on the lighting system,
you should always switch off the lights af‐
fected to prevent short circuits.
To avoid possible injury or equipment damage
when replacing bulbs, observe any instructions
provided by the bulb manufacturer.◀
Do not perform work/bulb replacement
on xenon headlamps
Have any work on the xenon lighting system,
including bulb replacement, performed only by
a service center. Due to the high voltage
present in the system, there is the danger of
fatal injuries if work is carried out improperly.◀
Do not touch the bulbs
Do not touch the glass of new bulbs with
your bare hands, as even minute amounts of
contamination will burn into the bulb's surface
and reduce its service life.
Use a clean tissue, cloth or something similar,
or hold the bulb by its base.◀
Light-emitting diodes (LEDs)
Some items of equipment use light-emitting
diodes installed behind a cover as a light
source.
These light-emitting diodes, which are related
to conventional lasers, are officially designated as Class 1 light-emitting diodes.
Do not remove the covers
Do not remove the covers, and never
stare into the unfiltered light for several hours;
otherwise, irritation of the retina could result.◀Headlamp glass
Condensation can form on the inside of the ex‐
ternal lamps in cool or humid weather. When
driving with the light switched on, the conden‐
sation evaporates after a short time. The head‐
lamp glasses do not need to be changed.
If the headlamps do not dim despite driving
with the light switched on, increasing humidity
forms, e. g. water droplets in the light, have the
service center check this.
Headlamp setting
The headlamp adjustments can be affected by
changing lamps and bulbs. Therefore after a
change, have the headlamp setting checked
and corrected by Service.
