Warning lamp
The warning lamp lights up when
Active Cruise Co ntrol has been
automatically deactivated, for exam-
ple due to a driving speed below 20 mph or
30 km/h or a DSC intervention. A message
appears on the Control Display.
Resuming stored desired speed and
distance
Briefly press th e button, arrow 4 .
The stored speed and distance are regained
and maintained.
In the following instance s, 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 neutral.
> In cars with automati c transmission: when
you engage selector lever position N.
> In cars with Sport automatic transmission
with double clutch: when you engage selec-
tor lever position N.
> When the ignition is switched off.

The indicator lights up as soon as the sys-
tem is activated.

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 page 93.<
Warning lamps
The indicator 2 flashes in red; a
signal sounds.
The system indicates that you
must brake and/or maneuver the
vehicle yourself. Active Cruise
Control cannot automati cally restore the dis-
tance 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 Con-
trol is deactivated. Yo u can reactivate the sys-
tem, if desired, by briefly pressing 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,

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, for example at a traffic light or when
approaching a parked vehicle. Also, the system
does not react to oncoming traffic, pedestrians
or other types of potentia l traffic such as a rider
on horseback. The system may also not detect
smaller moving objects such as motorcycles or
bicycles. Be especially alert when encountering
any of these situations as the system will nei-
ther 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 alertness. <
Active Cruise Control is not and must not
be used as a collisio n avoidance/warning
system. <
If while your vehicle is actively following a vehi-
cle in front of you and the vehicle ahead speeds
up or the lane ahead becomes clear, then your
vehicle will accelerate to the speed you have
selected. Be aware that changing to a clear,
unobstructed lane will also result in your vehicle
accelerating.
Be certain to deactiva te the system when
you pull into an exit lane for a highway off-
ramp. < Also, vehicles travelin
g in a staggered manner
on a highway may cause a delay in the system's
reaction to a vehicle in front of you or may cause
the system to react to a vehicle actually in the
lane next to you. Always be ready to take action
or apply the brakes if necessary.
While Active Cruise Co ntrol is capable of
braking your vehicle automatically when
you approach a slower vehicle ahead, it is
important to be aware that the ability of the sys-
tem to apply the brakes is also limited, e.g.
when you reduce your desired speed sharply.
The system cannot stop your vehicle. It uses
only a portion of braking system capacity and
does not utilize the full ca pacity of the vehicle
braking system. Therefore, the system cannot
decrease your speed for large differences in
speed between your vehicle and the vehicle
ahead. Examples: when you approach a vehicle
traveling at a much lower speed than your own
speed such as approaching a toll booth or when
a much slower vehicle cuts in front of you at
close range. <
Active Cruise Control ca n only decelerate the
vehicle to approx. 20 mph or 30 km/h.

Driving
Controls
Swerving vehicles
When a vehicle moves from an adjacent lane
into your lane, Active
Cruise Control will not
recognize this vehicle until it is fully in your lane
ahead of your vehicle.
When a vehicle ahead suddenly swerves
into your lane, the sy stem may not be able
to maintain the selected distance automatically.
This also applies to gr eat differences in speed
between you and vehicles ahead, e.g. when
quickly approaching a truck. There is a risk of
collision. Once the system has established that
a vehicle is indeed in fron t of you, it will indicate
that you must brake and/or maneuver the vehi-
cle yourself. Take action yourself; otherwise,
there is a risk of an accident. <
Behavior in curves
Because of the limited range of the system, it is
possible that in curves or on the peaks and val-
leys of hilly roads, a vehicle ahead may be rec-
ognized late, or not at all. Therefore, it is up to
the driver to select a speed that is prudent in
view of the curves and terrain of the roadway. In approaching a curve, it is possible that Active
Cruise Control would react briefly to a vehicle in
the adjacent lane. In ad
dition, the system can
sense if your vehicle is in a curve and may not
accelerate. If your vehicle decelerates in either
case, you can choose to overcome the deceler-
ation by briefly pressing the accelerator pedal.
Your responsibility
Your actions have priority at all times. When you
press the accelerator pedal while driving with
Active Cruise Control, the automatic braking
function will be temporar ily interrupted. Once
you release the accelera tor pedal, the desired
speed or the selected distance to the vehicle
ahead is achieved again.
Do not leave your foot on the accelerator
pedal and make sure that no objects such
as floor mats are lying on the accelerator pedal.
Otherwise, the system may not be able to brake
the vehicle. <

Outside temperature warning
When the displayed temperature sinks to
approx. +37 7/+3 6, a signal sounds and a
warning lamp lights up. There is an increased
risk of black ice.
Black ice can also form at temperatures
above +37 7/+3 6. You should there-
fore drive carefully on bridges and shaded
roads, for example; otherwise, there is an
increased risk of an accident. <

Cruising range
Displays the estimated cruising range available
with the remaining fuel. The range is calculated
on the basis of the way the car has been driven
over the last 18 miles/30 km and the amount of
fuel currently in the tank.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km; otherwise, engine functions are not
ensured and damage can occur. <
Average speed
Periods with the vehicle parked and the engine
switched off are not includ ed in the calculations
of average speed.
With the trip comp uter, refer to page85, you
can have the average speed for another trip dis-
played.
To reset average speed: press the button in the
turn signal/high beam lever for approx.
2seconds.
Average fuel consumption
The average fuel consumption is calculated for
the time during which the engine is running.
You can have the average consumption for
another trip displayed, re fer to Displays on the
Control Display below.
To reset average fuel consumption: press the
button in the turn sign al/high beam lever for
approx. 2 seconds.
Current fuel consumption
Displays the current fu el consumption. This
allows you to see whether your current driving
style is conducive to fuel economy with mini-

message includes indica tor and warning lamps
in the instrument cluster and, in some cases, an
acoustic signal and text messages at the top of
the Control Display.
Indicator and warning lamps
Indicator and warning lamps can light up in a
variety of combinations and colors.
Several of the lamps ar e checked for proper
functioning and light up temporarily when the
engine is started or the ignition is switched on.
Indicates that Check Control messages have
been stored. These Check Control messages
can be viewed again later, refer to page 93.
Text messages
Text messages at the upper edge of the Control
Display explain the meaning of the displayed
indicator and warning lamps.
Supplemental text messages
