Multi collision brake (MCB)Read and observe
on page 101 first.
MCB helps to decrease speed after a collision by means of automatic braking
interventions and to stabilise the vehicle. This reduces the risk of a subse-
quent crash due to uncontrolled vehicle movement.
The automatic brake interventions can take place only if the following condi-
tions are met.
There was a front, side and rear-end collision of a certain severity.
The impact speed was greater than approx. 10 km/h.
The brakes, the ESL and other required electrical systems remain function-
al after impact.
The accelerator pedal is not actuated.

The parking aid (hereinafter referred to as "system") draws attention to obsta-
cles in the vicinity of the vehicle via acoustic signals or on the Infotainment
display when manoeuvring.
WARNING■ The general information relating to the use of assistance systems must
be observed » page 100, in section Introduction .■
Moving persons or objects may not be recognised by the system sensors.
■
Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the system signals. There is a danger that such ob-
jects or people may not be recognised by the system sensors.
WARNING (Continued)■ External noise sources may affect the signals of the system sensors.
There is a danger that obstacles may not be recognised by the system sen-
sors.■
Before reversing, you should satisfy yourself that there are no small ob-
stacle, such as a rock, thin post etc., in front or behind your vehicle. Such
obstacles may not be recognised by the system sensors.
CAUTION
■ Keep the system sensors » Fig. 127 on page 103 clean, snow-and ice-free
and do not cover with any objects of any kind, otherwise the system function-
ing may be impaired.■
In adverse weather conditions (heavy rain, water vapour, very low or high
temperatures, etc.), the functioning of the system may be impaired - “incorrect
recognition of obstacles”.
■
Accessories additionally installed on the vehicle rear, such as bicycle carriers,
can impair the system function.

Read and observe and on page 103 first.
Activation
The activation of the system is initiated when the reverse gear is engaged, or
vehicles with the variant 2, also by pressing the button
» Fig. 130 .
When activating, an alarm sounds and the symbol illuminates in the button.
Deactivation
On vehicles with Version 1, the system can be deactivated by moving out of re-
verse gear.
For vehicles with variant 2, the system is automatically deactivated by pressing
the button or at a speed above 15 km/h (the
symbol in the button goes
out).
Displaying an error
If a warning signal sounds for 3 seconds after activating the system and there
is no obstacle close to your car, this indicates a system fault. The fault is also
indicated by the symbol flashing in the button. Seek help from a specialist
garage.
Note
The system can only be activated with the button at a speed of below 15
km/h.Automatic system activation when moving forwardFig. 131

Operation description

The Cruise Control System (CCS) maintains a set speed without you having to
actuate the accelerator pedal. The status where the CCS maintains the speed
is referred to hereinafter as the control.
ABC WARNING■
The general information relating to the use of assistance systems must
be observed » page 100, in section Introduction .■
After pressing the clutch pedal, no interrupted control occurs! For exam-
ple, if a different gear is engaged and the clutch pedal is released, control is
continued.

Basic requirements for starting the controlThe CCS is activated.
On vehicles with a manual transmission , the second gear or higher is en-
gaged.
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 20 km/h.
This, however, is only possible to the extent permitted by the engine output
and braking power of the vehicle.WARNINGIf the engine output or engine braking effect is insufficient to maintain the
set speed, the driver must assume control of the accelerator and brake
pedals!

▶ The brake pedal is operated.
▶ When one of the brake assist systems (e.g. ESC) intervenes.
▶ Through an airbag deployment.
▶ By pressing the button D

WARNING■ Always deactivate the cruise control system after use to prevent the sys-
tem being enabled unintentionally.■
Control may only be resumed if the set speed is not too high for the cur-
rent traffic conditions.
Note
■ During 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.■

Introduction
This chapter contains information on the following subjects:
Operation
109
Description of operation

The Speed Limiter limits the maximum driving speed to the set speed limit.
This limit can only be exceeded by depressing the accelerator pedal fully.
The condition in which the Speed Limiter monitors a potential set speed limit
excess is referred to as Regulation.

If no speed limit is set, the current speed is set as the speed limit.
After starting the system, the current speed is set as the speed limit, the
warning light lights up in the instrument cluster.
Exceeding the speed limit during the regulation
If, during the setting, it is necessary to exceed the speed limit (e.g. to over-
take), the accelerator pedal must be pressed fully.
When exceeding the speed limit (e.g. driving down a hill), an acoustic signal
sounds and the warning light flashes in the instrument cluster.
The regulation is resumed once the speed has fallen below the set limit.

The Adaptive Cruise 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 100.
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 100, in section Introduction .■
The driver must always be ready to take over the operation of the accel-
erator and brake pedal.
■
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).
■
Driving into “sharp” corners or in steep gradients / on steep inclines.
■
When driving through places where metal objects (such as metal build-
ings, railway 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.
