Indicator and warning lamps
The concept
Indicator and warning lamps can light up in a 
variety of combinations and colors.
Some lamps are checked for proper functioning 
and thus come on briefly when the engine is 
started or the ignition is switched on.
Explanatory text messages
Text messages at the lower edge of the Control 
Display explain the meaning of the displayed 
indicator and warning lamps.
You can call up more information, e.g. on the 
cause of a malfunction and on how to respond, 
via Check Control, refer to page83.
In urgent cases, this information will be shown 
as soon as the corresponding lamp comes on.

Deactivating cruise control
Tap the lever upwards or downwards, arrow3. 
The displays on the speedometer disappear.
In addition, the system is automatically deacti-
vated:
>When you brake the vehicle
>When you switch gears very slowly or shift 
to idle in cars with manual transmission
>When you select the automatic transmis-
sion's neutral position N
>When you activate DTC or deactivate DSC
>When DSC or ABS is intervening
Cruise control is not deactivated by depressing 
the accelerator pedal. Once the accelerator 
pedal is released, the stored speed is achieved 
again and maintained.
Warning lamp
The warning lamp comes on when 
cruise control has been deactivated 
by applying the parking brake or as a 
result of DSC intervention. A message appears 
on the Control Display.
Resuming a speed stored beforehand
Press the button, arrow4. The last stored 
speed is resumed and maintained.
In the following instances, the stored speed is 
deleted and can no longer be resumed:
>When driving stability control systems are 
intervening
>In ca rs  with manua l transmiss ion: when you 
shift gears very slowly or shift to idle posi-
tion
>In cars with automatic transmission: when 
you engage selector lever position N
>When the ignition is switched off

If --- mph or --- km/h temporarily appears 
in the instrument cluster display, it is pos-
sible that the system prerequisites for operation 
are currently not met. 
Calling up Check Control messages, refer to 
page84.<
Malfunction
The warning lamp comes on when 
the system has failed. A message 
appears on the Control Display. You 
can find more information starting on page83. 
Active cruise control*
The concept
With active cruise control, you can select a 
desired speed which is not only automatically 
maintained when driving on open roadways, but 
also varied to maintain a selected distance set-
ting as slower traffic is encountered.
Active cruise control is a technological advance 
over the familiar cruise control and is a welcome 
relief from the constant adjustment of speed 
that can accompany driving in traffic on high-
ways or other high-speed thoroughfares. Espe-
cially on longer trips, the system can reduce 
fatigue and tension, while increasing your 
enjoyment of driving. Please use it safely and 
responsibly.
Within the limits of its capability, the system 
automatically adapts the car's speed to that of a 
slower vehicle in front of you. You can specify

are currently not met. Calling up Check Control 
messages, refer to page84.<
Warning lamps
The indicator2 flashes in red; a 
signal sounds. 
The system indicates that you 
must brake and/or maneuver the 
vehicle yourself. Active cruise con-
trol cannot automatically restore the distance to 
the vehicle ahead. 
This indicator does not release you from your 
responsibility to adapt your desired speed and 
driving style to prevailing driving conditions.
The indicator 2 flashes in yellow. 
The prerequisites for operating 
active cruise control are not met, 
e.g. as a result of ABS or DSC 
interventions. Active cruise control 
is deactivated. You can reactivate the system, if 
desired, by tapping or pulling the lever when 
road and traffic conditions permit. It is not pos-
sible to resume a stored speed.
Radar sensor
The sensor's ability to detect vehicles ahead 
may be restricted as a result of heavy rain, dirt, 
snow or ice. If necessary, clean the radar sensor 
located in the front bumper, see arrow. Be sure 
to use particular care when removing any layers 
of snow or ice from the sensor.
When the radar sensor is not properly posi-
tioned, active cruise control cannot be activated 
at all.
Malfunction
The warning lamp comes on when 
the system has failed. A message 
appears on the Control Display. You 
can find more information starting on page83. 
System limitations
Always remember that the range and abil-
ity of the system does have physical limi-
tations. It will not apply the brakes or decelerate 
your vehicle when there is a slow-moving vehi-
cle, stopped vehicle or stationary object ahead 
of you, as for example, at a traffic light or a 
parked vehicle. Also, the system does not react 
to oncoming traffic, pedestrians or other types 
of potential traffic such as a rider on horseback. 
It is also possible that the system may not detect smaller moving objects such as motor-
cycles or bicycles. Be especially alert when 
encountering any of these situations as the sys-
tem will neither automatically brake, nor provide 
a warning to you. Also, be aware that every 
decrease in the distance setting allows your 
vehicle to come closer to a vehicle in front of 
you and requires a heightened amount of alert-
ness.< 

Everything under control
84  indicates that Check Control messages have 
been stored. You can view the Check Control 
messages whenever it is convenient for you.
Explanatory text messages
Text messages at the lower edge of the Control 
Display explain the meaning of the displayed
