Maintaining speed, storing speed,
and accelerating
Press lever to resistance point, arrow 1:
The speed currently being driven is maintained
and stored. The display1 in the speedometer,
see below, indicates this regulated speed.
Every time you press the lever, the vehicle's
speed increases by roughly 1 mph/1 km/h.
Press lever to resistance point for a longer time:
The vehicle accelerates without pressure on
the accelerator pedal. The system maintains
and stores your current speed as soon as you
release the lever.
Press the lever beyond the resistance point:
increase speed by 5 mph/10 km/h.
If, on a downhill grade, the engine's braking
effect is not sufficient, the controlled speed can
be exceeded. Speed can drop on uphill grades if
the engine output is insufficient.
Maintaining speed, storing speed, and
decelerating
Pull the lever, arrow2:
Functions are the same as1, only the vehicle
speed is reduced.
Interrupting cruise control
Press the lever up or down, arrow3.
In addition, cruise control is automatically deac-
tivated:
>When the brakes are applied
>When the clutch pedal is depressed or the
automatic transmission/SMG is shifted into
the N position
>When the DSC comes on
Resuming stored speed
Press button4:
The stored speed is resumed and maintained.
Deactivating system
When the ignition is switched off, the system is
deactivated and the stored speed is deleted.

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 technologically
advanced over the familiar cruise control and is
a welcome relief from the constant adjustment
of speed that can accompany driving in traffic
on freeways or other high-speed thorough-

Driving
66 fares. Especially 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 you 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. You can vary the distance, which
is additionally speed-dependent. Based on
your selected distance setting, the system
automatically decreases the throttle setting and
lightly applies the brakes if necessary. The vehi-
cle brake lamps will automatically illuminate to
signal a following driver to take action. In addi-
tion, 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 vehicle will acceler-
ate to the speed you have selected by increas-
ing the throttle setting and shifting gears auto-
matically or by the driver as needed. Your
selected speed will be held when driving down-
hill, too.
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 begin-
ning on page69.<
Navigation system Professional*
If a navigation DVD is in the drive, refer to
page124, the system adjusts the accelerating
and braking behavior of the vehicle to the road
you are driving on.
When the vehicle position is unknown, e.g.
when you leave the map area, this influence of
the navigation system is not available.
Manual transmission
You can shift with the cruise control activated.
Shifting information is provided or the system
deactivates itself if you drive at very high or very
low engine speeds for a longer period.
SMG
In the Sequential mode, shifting information is
provided or the system deactivates itself if you
drive at very high engine speeds for a longer
period.
In the Drive mode the SMG acts similarly to an
automatic transmission in the D position.

The speed currently being driven is stored and
maintained. It is indicated on the speedometer
and briefly in the instrument cluster.
The controlled speed can drop on uphill grades
if the engine output is insufficient. If the engine
braking effect is not sufficient on a downhill
grade, the system lightly brakes the vehicle.
Setting desired speed
Adjust your desired speed to the traffic
conditions and remain ready to brake at
all times, otherwise accidents can occur. Great
differences in speed to the vehicle ahead, e. g.
when quickly approaching a truck or when
another vehicle swerves into your lane, cannot
be compensated for by the system.<
Increasing in steps
Briefly press the lever repeatedly up to the
pressure point or past the pressure point,
arrow1, until the desired speed is displayed.
>Each time the lever is briefly pressed up to
the pressure point, the desired speed
increases by approx. 1 mph or 1 km/h.
>Each time the lever is briefly pressed
beyond the pressure point, the desired
speed is increased by a maximum of 5 mph
or 10 km/h until the maximum speed of
110mph or 180km/h is reached.
The speed then displayed is stored and
reached on clear roads.
Increasing steplessly
Press the lever up to the pressure point or past
the pressure point, arrow1, until the desired
speed is reached.
The speed then displayed is stored and
reached on clear roads.
Decreasing steplessly
Pull the lever up to the pressure point or past
the pressure point, arrow2, until the desired
speed is displayed.
>Each time the lever is pulled up to the pres-
sure point, the desired speed decreases by
approx. 1 mph or 1 km/h.
>Each time the lever is pulled beyond the
pressure point, the desired speed is
decreased by a maximum of 5 mph or
10 km/h until the minimum speed of
20 mph or 30 km/h is reached.
The speed then displayed is stored and
reached on clear roads.

Warning lamps
The display2 flashes red and a sig-
nal sounds.
The system requests that you
intervene by braking or with an
evasive maneuver. The active
cruise control cannot automatically restore the
distance to the vehicle driving ahead.
However, this display cannot relieve the driver
of the responsibility for adjusting the desired
speed and driving style to the traffic conditions.
The display 2 flashes yellow.
Automatic intervention by ABS or
DSC. The active cruise control
intervenes by braking until you
take over actively.
Radar sensor
Heavy rain, dirt, snow or ice can restrict the
detection of vehicles driving ahead. If neces-
sary, clean the front radar sensor under the
bumper. Exercise particular care when remov-
ing snow and ice.
If the sensor is not aligned properly, the active
cruise control cannot be activated.
Things to know about active cruise control
As with conventional cruise control sys-
tems, active cruise control in no way
diminishes or substitutes for the driver's own
personal responsibility, alertness and aware-
ness in adjusting speed, braking or otherwise
controlling the vehicle. The driver should
decide when to use the system on the basis of
road, traffic, visibility, and weather conditions.
Active cruise control is intended for use on
highway-type roadways where traffic is moving
relatively smoothly. Do not use this system in
city driving; heavy traffic such as during rush
hour; on curvy, winding roads, slippery roads or
roads with sharp curves such as highway off-
ramps; during inclement weather such as snow, strong rain or fog; or when entering inter-
changes, service/parking areas or toll booths.
It is also important to regulate your vehicle's
speed and distance setting within applicable
legal limits. Always be ready to take action or
apply the brakes if necessary, especially when
the system is actively following a vehicle in front
of you.<
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

In approaching a curve, it is possible that active
cruise control would react briefly to a vehicle in
the adjacent lane. In addition, 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.
Driver interventions
Anytime the driver presses down on the
accelerator pedal, any automatic braking
action by the system is interrupted until the
pedal is fully released. After doing this, release
the accelerator and the system again controls
your cruising speed and distance setting. While
driving with activated system, resting your foot
on the accelerator pedal will cause the system
not to brake even if necessary. Be certain that
floor mats or other objects on the vehicle floor
do not interfere with movement of the accelera-
tor pedal.<
While active cruise control 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 capacity 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.<
