Manual speed limiterPrinciple With the system, the speed can be restricted
from a value of 30 km/h/20 mph. There are no
restrictions below the set speed limit.
Exceeding the speed limit In particular situations the speed limit can be
deliberately exceeded by accelerating strongly.
The system gives a warning if the travelling
speed exceeds the set speed limit.
No brake intervention
If the set speed limit has been reached or unin‐
tentionally exceeded (for example driving
downhill) there is no brake intervention.
If you set a speed limit during the journey
which is below the current speed, the vehicle
rolls until the driving speed drops below the
speed limit.

Controls
Switching on Press the button on the steering
wheel.
The current speed is assumed as the speed
limit.
When switching on when at a standstill
30 km/h/20 mph is set as the speed limit.
The speedometer marker is set to the corre‐
sponding speed.
When activating the speed limit it is possible
that Dynamic Stability Control, DSC is activa‐
ted.
Switching off Press the button on the steering
wheel.
For example, the system is also deactivated in
the following situations:▷When engaging reverse gear.▷When switching the engine off.▷When switching on Cruise Control.
The indicators turn off.
Change speed limit
Press the rocker switch repeatedly upwards or
downwards until the desired speed limit is set.
▷Every time the rocker switch is pressed to
the resistance point, the speed limit is in‐
creased or decreased by approximately
1 km/h, approximately 1 mph.▷Each time the rocker switch is pressed be‐
yond the resistance point, the speed limit
is increased or decreased to the next multi‐
ple of 10 km/h on the speedometer display.
If you set a speed limit during the journey
which is below the current speed, the vehicle
rolls until the driving speed drops below the
speed limit.

Warning
Visual warning The indicator light in the instrument
cluster flashes if the set speed limit is
exceeded for as long as you exceed the
set speed limit.
Acoustic warning▷If you unintentionally exceed the set speed
limit, you will hear an acoustic warning af‐
ter approximately five seconds.▷If the speed limit is reduced to below the
current speed during the journey, the
warning sounds after approximately
30 seconds.▷If you intentionally exceed the speed limit
by fully depressing the accelerator pedal,
no warning is given.
Displays in the instrument cluster
Marking of the speed limit Display in the speedometer:
▷Marker illuminates green:

Attentiveness assistant
Principle The system can detect increasing inattentive‐
ness or tiring of the driver on long monotonous
drives, for example on motorways. In this situa‐
tion, it is recommended that you take a break.
Note WARNING
The system does not take your personal
responsibility from you when you are estimat‐
ing your physical condition. Increasing inatten‐
tion or fatigue might not be detected, or not in
good time. Danger of accidents. Make sure
that the drive is rested and alert. Adapt driving
style to the driving conditions.◀
Function The system is switched on every time the en‐
gine is started and cannot be switched off.
After the start of the drive, the system is adap‐
ted to the driver so that an increase in inatten‐
tion or fatigue can be detected.
This process considers the following criteria:▷Personal driving style, for example, steer‐
ing.▷Drive conditions, for example, time of day,
duration of drive.
The system is active from approxi‐
mately. 70 km/h, 43 mph and can display a rec‐
ommendation to take a break
Recommendation to take a break
With increasing inattention or tiredness of the
driver, an instruction is shown on the control
display with the recommendation to take a
break.
A recommendation to take a break will only be
displayed once during an uninterrupted trip.
After a break, at the earliest another break rec‐
ommendation may be displayed after approxi‐
mately 45 minutes.
System limits
The function may be restricted in situations
such as the following and no warning or a
wrong one is triggered:▷If the time is wrongly set.▷If the speed driven falls considerably below
70 km/h, 43 mph.▷For sporty driving style, for example, with
heavy acceleration or fast cornering.▷In active drive situations, for example, fre‐
quent lane change.▷With bad road conditions.▷With high side-wind.
PreCrash
Principle With the system from 30 km/h/20 mph critical
driving situations may occur, which could
cause an accident. In these situations, auto‐
matically preventative, protective measures
are taken to minimise the risk of accident.
Critical driving situations are, for example:
▷Full braking.▷Heavy understeering.▷Heavy oversteering.
When collision warning or front-end collision
warning with braking function is fitted, within
the limits of the system, threatened collisions
into vehicles in front or stationary vehicles are
detected.
Note WARNING
The system does not take your personal
responsibility from you. Critical situations can‐
not be detected reliably or in good time due to
limitations of the system. Danger of accidents.
Adapt driving style to the driving conditions.
Observe the traffic situation and intervene ac‐
tively if the situation warrants it.◀

Function
After fastening the belt, the front belts are au‐
tomatically pretensioned once when driving
away.
When driving in critical situations, the following
individual functions become active as required:▷The front belts are automatically preten‐
sioned.▷The windows are automatically closed.▷The Glass Roof automatically closes.
After a critical driving situation without acci‐
dent, the front belts are released again. All
other systems can be put back into the desired
setting.
If the belt tension does not loosen automati‐
cally, stop the vehicle and open the seat belt
using the red button in the lock section. Fasten
the seat belt again before continuing your jour‐
ney.
PostCrash The system can automatically bring the vehicle
to a standstill in certain accident situations
without the involvement of the driver. The risk
of a further collision and its consequences can
thereby be reduced.
By depressing the brake pedal, the vehicle can
be decelerated much faster. The automatic
braking is interrupted as a result. By pressing
the accelerator pedal, automatic braking is also
interrupted.
After reaching a standstill, the brake is auto‐
matically triggered. Then secure the vehicle
against rolling away.
