Indicator and warning lamps
The concept
Indicator and warning lamps and their combina-
tions appear in the indicator area1 and in the
display2. For better differentiation of malfunc-
tions, different symbols can appear in the dis-
play 2.
Some lamps in the indicator area1 are checked
for proper operation when the engine is started
or the ignition is switched on and light up briefly
in the process.
Confirmation of active functions
The following indicator lamps in the indicator
area1 indicate that certain functions are active:
Required action in case of a
malfunction
All warning lamps and indicator lamps not pre-
viously listed are also accompanied by text
messages at the bottom of the Control Display.
These may contain detailed information on the
cause of a malfunction and the corresponding
action required.
Sometimes warning lamps are also accompa-
nied by additional text messages on the Control
Display which are displayed immediately. Text
messages which do not appear immediately are
stored and can be displayed at a later time. For
details on displaying these messages later,
refer to Check Control on page71. Turn signals60

tion to stop the movement.
After switching off ignition
You can still operate the sunroof:
>for approx. 15 minutes when the ignition
key is in position 1.
>for approx. 1 minute in position 0 or with the
ignition key removed, as long as a door has
not been opened.For information on using the convenience oper-
ation mode at the door lock or with the remote
control, refer to page30 or31.
Anti-trapping mechanism
If the glass sunroof encounters resistance when
closing, the closing action is interrupted and the
glass sunroof opens.
If the sliding panel encounters resistance when
closing within the last approx. 8 in/20 cm, the
closing action is interrupted and the sliding
panel opens again slightly.
Despite the anti-trapping mechanism,
you should inspect the sunroof's travel
range prior to closing it, as the safety feature
might fail to detect certain kinds of obstruc-
tions, such as very thin objects, and the sunroof
would continue closing.
Pressing the switch beyond the resistance
point and holding it deactivates the anti-trap-
ping mechanism.<
Following interruptions in electrical
power supply
After an interruption in the power supply the

Cleaning windshield and headlamps
The system sprays washer fluid against the
windshield and activates the wipers for a brief
period.
When the vehicle lighting system is switched
on, the headlamps are also cleaned at regular
and appropriate intervals.
Do not use the washers if there is any
danger that the fluid will freeze on the
windshield. If you do so, your vision could be
obscured. To avoid freezing, use a washer fluid
antifreeze, refer to Washer fluid.
Do not use washers when the washer fluid res-
ervoir is empty, as otherwise the washer pump
will be damaged.<
Windshield washer nozzles
The windshield washer nozzles are automati-
cally heated in ignition key position 2.
Washer fluid
Washer fluid antifreeze is flammable.
Always keep it well away from sparks and
open flames, and store it in tightly closed con-
tainers well out of the reach of children. Always
observe the instructions for use provided on the
containers.<
Washer fluid reservoir
Capacity approx. 5.3 US quarts/5 liters
Fill with water and – if required – with a washer
antifreeze, according to manufacturer's recom-
mendations.
In order maintain the mixture ratio, mix
the washer fluid before filling.<
Cruise control
The concept
The cruise control is available for use at speeds
of approx. 20 mph/30 km/h and higher. The
vehicle maintains and stores the speed that you
set using the lever mounted on the steering col-
umn.
Do not use the cruise control under driv-
ing conditions that do not permit a con-
stant speed, e.g.when driving on winding roads,
in heavy traffic or in poor road conditions such
as snow, rain, ice, and loose road surface.<

cially on longer trips, the system can reduce
fatigue and tension, while increasing your
enjoyment of driving. Please use it safely and
responsibly.
In addition to holding a steady cruising speed, if
you encounter slower vehicles ahead, active
cruise control will, within the scope of given
possibilities, adjust your vehicle's speed auto-
matically so that one can flow with the traffic
without having to make constant adjustments.
If, for example, while cruising at the selected
speed, you begin to approach a slower vehicle
ahead of you in the same lane, the system will
reduce your vehicle's speed to the same as that
of the vehicle ahead to maintain your selected
distance setting between your vehicle and the
vehicle ahead. There are four settings for dis-
tance, which are additionally speed-dependent.
Based on your selected distance setting, the
system automatically decreases the throttle
setting and lightly applies the brakes if neces-
sary. The vehicle brake lamps will automatically
illuminate to signal 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 transmission your vehicle is
equipped with, to maintain the distance setting
selected. If the vehicle ahead speeds up or
when the lane ahead becomes clear, your vehi-
cle will accelerate to the speed you have
selected by increasing the throttle setting and
shifting gears automatically or by the driver as
needed.
Active cruise control is not and must not
be used as a collision avoidance/warning
system.<
Since this active cruise control system is
a new technology and operates differ-
ently from conventional cruise control systems
which you may be accustomed to, you are
strongly urged to read all of the pages relating
to this system before use. Pay special attention
to the information contained in the Things to
know about active cruise control section in this
manual beginning on page66. You can use the system in the 2nd to 6th gear
within a normal engine speed range and also
change gears. Continuous operation at very
high or very low engine speeds is not possible.
In this case the driver is asked to shift or the
system deactivates itself.
Vehicles with SMG
Continuous operation at very high engine
speeds is not possible in the Sequential mode.
In this case the driver is asked to shift or the
system deactivates itself.
In the Drive mode the SMG acts similarly to the
automatic transmission in the D position.

2Activate system, store and decrease

3Deactivate system
4Recall the stored speed and distance or
increase desired speed by 1 mph/1 km/h
with each press of the button
5Select distance to vehicle driving ahead.
You can choose from four available distance
settings. You will find more detailed infor-
mation on page65.
Adjust your desired speed to the traffic
conditions and remain ready to brake at
all times. Great differences in speed to the vehi-
cles driving ahead, e. g. when quickly approach-
ing a truck or when another vehicle swerves into
your lane, cannot be compensated for by the
system.<
