Operation
Road signs detection system* 1)Fig. 78
On the instrument panel display: ex-
ampl es of speed limits or o v
ert aking pr
ohibi-
tions with their respective additional signs. The traffic sign detection system records the
st
andar
d traffic signs in fr
ont of the v

ehicle
with a camera located on the base of the in-
terior mirror and provides information about
speed limits and overtaking prohibitions. Within its limitations, the system also displays
additional signals, such as time-specific pro-
hibitions, signs for vehicl

es towing trailers

Braking and parking
Electronic differential lock (EDL)
When the EDL det ects wheel
spin, it brak
es
the spinning wheel and dir
ects the power to
the other driven wheel. This function is active
up to approximately 100 km/h (62 mph).
To prevent the disc brake of the braked wheel
from overheating, the EDL cuts out automati-
cally if subjected to excessive loads. The ve-
hicle can still be driven. The EDL will switch on
again automatically when the brake has
cooled down.
Tractor-trailer sway mitigation*
If the vehicle is pulling a trailer, it will control
the following: tractor-trailers tend to sway.
When the swaying of the trailer is felt by the
vehicle and detected by the ESC, it will auto-
matically brake the towing vehicle within the
limits of the system and mitigate the sway.
Tractor-trailer sway mitigation is not available
in all countries

We recommend taking the vehicle to a speci-
alised w orkshop t

Trailer mode On vehicles with a factory-fitted trailer hitch,
when the trailer is connected, the r
ear sen-
sors will not activ

ate when reverse gear is en-
gaged or button  is pressed. Therefore, any
objects behind or to the side of the vehicle
will not be indicated on the screen and no
audio signals will sound.
The screen will only display objects detected
at the front, and the vehicle

Intr oduction Take into account country-specific regula-
tions about driving with a trailer and the use
of a to wing br
acket.
The vehicle has been developed primarily for
carrying people, although it can also be used
to tow a trailer if fitted with the corresponding
technical equipment. This additional load has
an effect on the useful life, fuel consumption
and vehicle performance and in some cases
can reduce the service intervals.
Driving with a trailer requires more force from
the vehicle, and thus more concentration
from the driver.
In winter, winter tyres should be fitted on both
the vehicle and the trailer.

13 Earth for pin 9 Power socket for trailer
The vehicle is fitted with a 13-pol
e po
wer
socket for the connection between the trailer
and the vehicle. With the engine running,
electrical devices on the trailer receive power
from the electrical connection (pin 9 and pin
10 of the trailer power socket).
If the system detects that a trailer has been
connected, the consumers on the trailer will
receive electricity through this connection
(pins 9 and 10). Pin 9 has a permanent live.
This powers, for example, the trailer
