Indicator and warning lamps
The concept
Indicator and warning lamps can light up in var-
ious combinations and colors in both the indica-
tor area 1 and the display 2.
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 page79.In urgent cases, this information will be shown
immediately as soon as the corresponding lamp
comes on.

luggage compartment lid is closed, the luggage
compartment lid will reopen slightly. The hazard
warning flashers flash and an acoustic signal
*
sounds.<
Unlocking just the luggage
compartment lid
Press the button on the outside of the luggage
compartment lid. This corresponds to pressing
the button.
Switching on radio readiness
Radio readiness is switched on by pressing the
start/stop button, refer to page52.
Do not depress the brake or the clutch,
otherwise the engine will start immedi-
ately.<
Starting the engine
You can start the engine or switch on the igni-
tion when a remote control is inside the vehicle.
It is not necessary to insert a remote control into
the ignition switch, refer to page52.
Switching off the engine in vehicles
with automatic transmission
The engine can only be switched off when the
selector lever is in position P, refer to page54.
To switch the engine off when the selector lever
is in position N, the remote control must be in
the ignition switch.
Before driving a vehicle with automatic
transmission into a car wash
1.Insert remote control into ignition switch.
2.Depress the brake.
3.Move the selector lever to position N.
4.Switch off the engine.
The vehicle can roll.
Malfunction
Convenient access may malfunction due to
local radio waves. If this happens, open or close
the vehicle via the buttons on the remote con-
trol or using the integrated key. To start the
engine afterward, insert the remote control into
the ignition switch.
Warning lamps
The warning lamp in the instrument
cluster lights up when you attempt to
start the engine: the engine cannot
be started. The remote control is not inside the
vehicle or is malfunctioning. Take the remote
control with you inside the vehicle or have it
checked. If necessary, insert another remote
control into the ignition switch.
The warning lamp in the instrument
cluster lights up while the engine is
running: the remote control is no
longer inside the vehicle. After the engine is
switched off, the engine can only be restarted
within approx. 10 seconds.

to idle in cars with manual transmission
>When you select the automatic transmis-
sion's/SMG's neutral position N

>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 automatically
deactivated by engaging the hand-
brake or as a result of DSC intervening. A mes-
sage appears on the Control Display.
Resuming a speed stored beforehand
Briefly press the button, arrow 4. the 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 cars with manual transmission: when you
shift gears very slowly or shift to idle posi-
tion
>With automatic transmission/SMG: when
you engage selector lever position N

are currently not met.
Calling up Check Control messages, refer to

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 page79.
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
the distance to be maintained from the vehicle
in front in four stages. For safety reasons, the
distance is speed-dependent. Based on your
selected distance setting, the system automat-
ically decreases the throttle setting and lightly
applies the brakes if necessary. The vehicle
brake lamps will automatically illuminate to sig-
nal a following driver to take action. In addition,
it may be necessary for the vehicle or the driver
to downshift, depending on the kind of trans-
mission your vehicle is equipped with, to main-
tain the distance setting selected. If the vehicle
ahead speeds up or when the lane ahead

The indicator lights up as soon as the sys-
tem is activated.
4Selected desired speed is temporarily dis-
played
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 page80.<
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 deacti-
vated. You can reactivate the system, if desired,
by tapping or pulling the lever when road and
traffic conditions permit. It is not possible 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 page79.
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
