Control active (in the colour display the digits of the speed limits are high-
lighted).
No speed set.
System fault - seek assistance from a specialist garage immediately.
Basic requirements for start of control The CCS is activated.
On vehicles with manual transmission , second gear or higher is engaged.
On vehicles with an automatic transmission , the selector lever is in the
D/S position or in the Tiptronic position.
The current speed is higher than approx. 20 km/h.
This is only possible within the range which is permitted by the power output
and braking power of the engine.
WARNINGIf the engine power or engine braking effect is insufficient to maintain the
set speed, the driver must take control of vehicle operation.Operating DescriptionFig. 168

If no speed is set, the current speed is used.
At the start of the control process, the CCS regulates the vehicle to the current
speed, and this speed is shown on the instrument cluster display. The warning
light illuminates in the instrument cluster.
Automatic control interruption
Automatic control interruption occurs if any of the following conditions are met. ▶ The brake pedal is operated.
▶ When one of the brake assist systems (e.g. ESC) intervenes.
▶ Through an airbag deployment.
WARNING■ Always deactivate the cruise control system after use to prevent uninten-
tional switching on of the system.■
Control may only be resumed if the set speed is not too high for the cur-
rent traffic conditions.

NoteDuring control, speed can be increased by pressing the accelerator pedal. Re-
leasing the accelerator pedal will cause the speed to drop again to the set
speed.

The automatic distance control (hereinafter referred to as ACC) maintains the
set speed or the distance to the vehicle ahead without the accelerator or
brake pedal being pressed.
The front of the vehicle and the distance to the vehicle ahead is monitored by
a radar sensor » page 135.
The state in which the ACC maintains the speed or the proximity is described
as control from here on.
WARNING■
The general information relating to the use of assistance systems must
be observed » page 135, in section Introduction .■
The driver must always be ready to take over steering of the vehicle him-
self (accelerate or brake).
■
The ACC does not react when approaching a stationary obstacle, such as
traffic jams, vehicle breakdowns or vehicles waiting at a traffic light.
■
The ACC does not respond to crossing or oncoming objects.
■
If the ACC does not decelerate fast enough, immediately apply the vehi-
cle's foot brake.
WARNINGFor safety reasons, do not use the ACC under the following conditions.■When driving in turning lanes, motorway exits or construction sites, to
avoid an unwanted acceleration to the stored speed.■
When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
■
When road conditions are poor (e.g. ice, slippery road, gravel, dirt road).
■
When driving around “sharp” bends.
■
When riding on a steep gradient / high slope.
■
When driving through places where metal objects (such as metal build-
ings, railroad tracks, etc.) can be found.
■
When driving through very divided and enclosed spaces (such as large-ca-
pacity garages, car ferries, tunnels and the like.).
Note
■ The ACC is designed primarily for use on motorways.■The ACC reduces the speed by automatically releasing the accelerator or by
means of a braking procedure as appropriate. If the brakes are used for an au-
tomatic speed reduction at any moments, then the brake light illuminates.■
In case of failure of more than one brake light on the vehicle or on the con-
nected trailer, the ACC becomes unavailable.
■
The control automatically cancels the engagement of the brake supportive
assistance systems (e.g. ESC) or when the maximum permitted engine speed is
exceeded.

Engine / drive
The vehicle acceleration is more dynamic than in Normal
mode.

The driving force distribution between the front wheels is adapted to the spor-
ty driving style.
Adaptive Cruise Control (ACC)
The acceleration is quicker than in
Normal
mode with distance control

ProActive passenger protection
The first level of protection is deactivated » page 160.
Engine noise
The engine noise is noticeable in the interior more intensely than in
Normal
mode.
Eco
mode
Read and observe
on page 157 first.
This mode is suitable for a relaxed style of driving and helps to save fuel.
Selecting this mode primarily affects the function of the following systems.
Engine / drive
Vehicle acceleration is more relaxed than in
Normal
mode.
The recommended gear is controlled such to achieve the lowest possible fuel
consumption » page 41.
When the START-STOP system was deactivated manually » page 124, it is au-
tomatically activated.
The automatic gearbox is set automatically to mode E » page 129 .
Adaptive Cruise Control (ACC)
Acceleration occurs more relaxed than in
Normal
» page 150 mode with distance
control.
Xenon headlight
The system is in economic mode » page 70. The headlamps are in basic setting
and do not adapt to the direction of travel.
Air conditioning (Climatronic)
The air conditioning is controlled so as to save energy. For this reason, for ex-
ample, it may take longer to reach the desired interior temperature in modeNormal
.
Note
■ The mode Eco is not available when towing a trailer or when another acces-
sory is connected to the trailer socket. If the vehicle is in drive mode Eco
and a
trailer is hitched up or another accessory is connected, the vehicle is automati-
cally set to the driving mode
Normal
.
■
The maximum vehicle acceleration (kick down function) is possible also in
driving mode
