becomes clear, your vehicle will accelerate to
the speed you have selected by increasing the
throttle setting and shifting gears automatically
or by the driver as needed. Your selected speed
will be held when driving downhill, too.
Since this active cruise control system is a new
technology and operates differently from con-
ventional 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 System
limitations section beginning on page66.
Braking sensation
The system's automatic brake operation results
in a braking sensation that is slightly different
from what you feel when you brake the vehicle
yourself in a similar situation. Possible noises
during automatic deceleration are normal.
Manual transmission/SMG
You can shift gears while cruise control is acti-
vated. An indicator lamp notifies you that you
should shift gears when you drive for an
extended period at very high or very low engine
speeds, or the system is deactivated.
In Drive mode, the SMG acts similarly to an
automatic transmission in position D.
Range of applications
The minimum desired speed is 20 mph or
30 km/h, and the maximum desired speed is
110 mph or 180 km/h.
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. Otherwise, driving conditions could
result which violate the law or pose a risk of
accident.<

Maintaining 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.

Driving
64 The car's current speed is stored and main-
tained. It is displayed in the speedometer and
briefly in the instrument cluster.
On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If the engine braking
effect is insufficient on downhill slopes, the sys-
tem will brake the vehicle slightly.
Adjusting desired speed
Adjust your desired speed to the traffic
conditions and remain ready to brake at
all times, otherwise there is a risk of accident.
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 increments
Repeatedly tap the lever to the resistance point
or beyond, arrow1, until the desired speed is
reached.
>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.
Increasing continuously
Repeatedly press the lever to the resistance
point or beyond, arrow1, until the desired
speed is reached.The speed then displayed is stored and
reached as soon as the road ahead of you is
clear.
Decreasing in increments
Repeatedly pull the lever to the resistance point
or beyond, arrow 2, until the desired speed is
reached.
>Each time the lever is pulled to the resis-
tance point, the desired speed is decreased
by approx. 1 mph or 1 km/h.
>Each time the lever is pulled beyond the
resistance point, the desired speed is
reduc ed by up to 5 mph o r 10 km/h until the
minimum speed of 20 mph or 30 km/h is
achieved.
The speed then displayed is stored and
achieved on a clear road.

Use good judgement to select the appro-
priate following distance given road con-
ditions, traffic, applicable laws and driving rec-
ommendations for safe following distance.
Otherwise, you may be in violation of the law or
an accident could result.<
Deactivating cruise control
Press the lever upward or downward, arrow3.
The displays in 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 idle in cars with manual transmission
>When you select the automatic transmis-
sion's/SMG'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 page66
>When you apply the handbrake
When the system is deactivated, you
must brake the vehicle yourself and/or
maneuver as necessary, otherwise there is a
risk of accident.<
Warning lamp
The warning lamp comes on when
active cruise control has been auto-
matically deactivated due to a driving
speed below 20 mph or 30km/h, an application
of the handbrake or a DSC intervention. A mes-
sage appears on the Control Display.
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 idle posi-
tion
>With automatic transmission/SMG: when
you engage selector lever position N
>When the ignition is switched off

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.
Fuel gauge
Fuel tank capacity: approx. 15.9 US gallons/
60 liters. You can find information on refueling
on page186.
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, a message briefly appears on the Control
Display and the cruising range for the remaining
amount of fuel is displayed on the computer.
Under a cruising range of approx. 30 miles/
50 km, the message remains in the Control Dis-
play.
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.<
