Storing current speed
Briefly press the lever, arrow 1, or briefly pull it,
arrow 2, at a driving speed of more than approx.
20 mph or 30 km/h.
The car's current speed is stored. It is displayed
on the speedometer and briefly in the instru-
ment cluster.
Increasing desired speed
Press or tap the lever to the resistance point or
beyond, arrow1, until the desired speed is dis-
played.
>Each time the lever is tapped to the resis-
tance point, the desired speed is increased
by approx. 1 mph or 1 km/h.
>Each time the lever is tapped beyond the
resistance point, the desired speed is
increased by up to 5 mph or 10 km/h until the maximum speed of 110 mph or
180 km/h is achieved.
The speed then displayed is stored and
achieved on a clear road.
Decreasing desired speed
Pull the lever, arrow 2, until the desired speed is
displayed.
The other functions work analogously to those
described under Increasing desired speed.
Selecting distance
>Press downward:
Increase distance.
>Press upward:
Decrease distance.
The selected distance is displayed in the instru-
ment cluster.
Distance 1
Distance 2
Distance 3
Distance 4
This is always the preset dis-
tance when you use the system
for the first time after starting the
engine.

Use good judgment to select the appro-
priate following distance given road con-
ditions, traffic, applicable laws and driving rec-
ommendations for safe following distance.
Otherwise, an accident risk could result.<
Deactivating cruise control
Press the lever upward or downward, arrow3.
The displays on the speedometer disappear.
In addition, the system is automatically deacti-
vated:
>When you brake the vehicle
>When the speed is reduced to below
20 mph or 30 km/h due to a traffic situation
>When you switch gears very slowly or shift
to neutral in cars with manual transmission
>When you select the automatic transmis-
sion's neutral position N
>When you activate the Dynamic Traction
Control DTC
>When you deactivate the Dynamic Stability
Control DSC
>When DSC or ABS is intervening
>When the system does not recognize any
objects for a longer period of time, e.g. on
infrequently traveled roads without a shoul-
der or guard rails, or if the radar sensor is
covered with dirt, refer to page58
>When you apply the parking brake
When the system is deactivated, you
must brake the vehicle yourself and/or
maneuver as necessary; otherwise, there is a
risk of accidents.<
Warning lamp
The warning lamp comes on when
active cruise control has been auto-
matically deactivated, for example
due to a driving speed below 20 mph or
30 km/h or a DSC intervention.
Resuming stored desired speed and
distance
Briefly press the button, arrow 4.
The stored speed and distance are regained
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 neutral
>In cars with automatic transmission: when
you engage selector lever position N
>When the ignition is switched off

in the instrument cluster display, it is pos-

are currently not met. Calling up Check Control
messages, refer to page68.<
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.
The system cannot be activated if the sensor is
incorrectly aligned.
For US owners only
The transmitter and receiver units comply with
part 15 of the FCC/Federal Communications
Commission regulations. Operation is gov-
erned by the following:

Outside temperature warning
When the displayed temperature sinks to
approx. +377/+36, 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 +377/+36. You should there-
fore drive carefully on bridges and shaded roads, for example; otherwise, there is an
increased risk of an accident.<

Coolant temperature
A warning lamp will come on if the coolant, and
therefore the engine, becomes too hot.
Check coolant level, refer to page140.
Energy Control*
Displays the current fuel consumption. This
allows you to see whether your current driving
style is conducive to fuel economy with mini-
mum exhaust emissions.
Engine oil temperature*
When the engine is at normal operating temper-
ature, the engine oil temperature is between
approx. 2107/1006 and approx. 3007/
1506.
If the engine oil temperature is too high, a warn-
ing lamp comes on in the instrument cluster.
Fuel gauge
Fuel tank capacity: approx. 16.1 gallons/
61 liters.
You can find information on refueling on
page115.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Reserve
Once the fuel level has fallen to the reserve
zone of approx. 2.1 US gallons/8 liters for gaso-
line engines and approx. 1.7 US gallons/
6.5 liters for diesel engines, the indicator lamp
and the cruising range for the remaining
amount of fuel are displayed briefly. The indica-
tor lamp remains permanently on when the
remaining range is less than approx. 30 miles/
50 km.
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.<

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 included in the calculations
of average speed.
To reset average speed: press the button in the
turn indicator lever for approx. 2 seconds.
Average fuel consumption
The average fuel consumption is calculated for
the time during which the engine is running.
To reset average fuel consumption: press the
button in the turn indicator lever for approx.
2seconds.
Current fuel consumption*
Displays the current fuel consumption. This
allows you to see whether your current driving
style is conducive to fuel economy with mini-
mum exhaust emissions.
