Speed limit detection
The concept
Speed limit detection
Speed limit detection shows the current maxi‐
mum permitted speed in the instrument clus‐
ter. The camera at the base of the interior rear‐
view mirror detects traffic signs at the edge of
the road as well as variable overhead sign
posts. Traffic signs with extra symbols for wet
road conditions, etc. are also detected and
compared with the vehicle's onboard data,
such as for the rain sensor, and will be dis‐
played depending on the situation.
With the navigation system, the system takes
into account the information stored in the navi‐
gation data and also displays speed limits
present on routes without signs.
Without a navigation system, the system is sub‐
ject to limitations imposed by technology.
Speed limits with extra text characters are al‐
ways displayed.
Information
Speed limits when towing a trailer are not
shown.
WARNING
The system does not relieve from the per‐
sonal responsibility to correctly assess visibility
and traffic situation. There is risk of an accident.
Adjust the driving style to the traffic conditions.

participants early on and automatically
switches the high beams on or off depending
on the traffic situation. The assistant ensures
that the high beams are switched on, whenever
the traffic situation allows. In the low speed
range, the high beams are not switched on by
the system.
General information
The system responds to light from oncoming
traffic and traffic driving ahead of you, and to
adequate illumination, e.g., in towns and cities.
The driver can intervene at any time and switch
the high beams on and off as usual.

tem checked, repaired, dismantled and scrap‐
ped by a dealer’s service center or another
qualified service center or repair shop.◀
Correct function
When the ignition is switched on, the
warning lamp in the instrument cluster
lights up briefly and thereby indicates
the operational readiness of the entire airbag
system and the belt tensioner.

Automatic deactivation of the front-
seat passenger airbags
The concept
The system reads if the front passenger seat is
occupied by measuring the human body's re‐
sistance.
Front, knee and side airbag on the front pas‐
senger's side are either activated or deacti‐
vated.
Information
Before transporting a child on the front passen‐
ger seat, refer to the safety notes and instruc‐
tions for children on the front passenger seat,
see Children.
WARNING
The ensure the front-seat passenger air‐
bag function, it must be detected, whether a
person occupies the front passenger seat. The
entire seat cushion area must be used for this
purpose. There is risk of injuries or danger to
life. Make sure that the front passenger keeps
his or her feet in the floor area.◀
Malfunction of the automatic
deactivation system
When transporting older children and adults,
the front-seat passenger airbags may be deac‐
tivated in certain sitting positions. In this case,
the indicator lamp for the front-seat passenger
airbags lights up.
In this case, change the sitting position so that
the front-seat passenger airbags are activated
and the indicator lamp goes out.
If it is not possible to activate the airbags, have
the person sit in the rear.
To enable correct recognition of the occupied
seat cushion.
▷Do not attach covers, cushions, ball mats or
other items to the front passenger seat un‐
less they are specifically determined to be
safe for use on the front passenger seat.
▷Do not place any electronic devices on the
passenger seat if a child restraint system is
to be installed on it.
▷Do not place objects under the seat that
could press against the seat from below.
▷No moisture in or on the seat.
