A resistance point can be felt when
moving the lever.
Constant flashing is activated when
the lever is being moved beyond the
resistance point. It is deactivated
when the steering wheel is moved in
the opposite direction or lever is
manually moved back to its neutral
position.
Activate temporary flashing by
holding the lever just before the
resistance point. Turning lights will
flash until lever is being released.
To activate three flashes, tap the
lever briefly without passing the
resistance point.
With a trailer connected, turn signal
flashes six times and tone frequency
changes when pressing the lever until
resistance is felt and then releasing.
Move the lever to the resistance point and hold for flashing until lever is
released.

Fault
Fault messages are displayed with a 9 on the top line of the Info Display.
The rear view camera may not
operate properly when:
● The surrounding is dark.
● The sun or the beam of headlights is shining directly into
the camera lens.
● Ice, snow, mud, or anything else covers the camera lens. Clean
the lens, rinse it with water, and
wipe it with a soft cloth.
● The vehicle is towing a trailer.● The vehicle had a rear end accident.
● There are extreme temperature changes.
Traffic sign assistant
Functionality
The traffic sign assistant system
detects designated traffic signs via a
front camera and displays them in the
Driver Information Centre.
Traffic signs which will be detected
are:
Driving and operating165Limit and no passing signs● speed limit
● no passing
● end of speed limit
● end of no passingRoad signs
Beginning and end of:
● city regions (country specific)
● motorways
● A-roads
● play streetsAdd-on signs ● additional hints to traffic signs
● restriction of trailer towing
● tractor constraints
● wet warning
● ice warning
● direction arrows
Speed limit signs are displayed in the
Driver Information Centre until the
next speed limit sign or end of speed
limit is detected or up to a defined sign
timeout.
Combinations of multiple signs in the
display are possible.
An exclamation mark in a frame
indicates that there is an additional
sign detected which is not recognised
by the system.
The system operates without loss of
performance up to a speed of
200 km/h depending on the lighting
conditions. At night the system is
active up to a speed of 160 km/h.
Display indication
Information about the currently valid
traffic signs is available on the
designated traffic sign assistant page in the Driver Information Centre.
Additionally, the currently valid speed
limit is displayed permanently in the
lower line of the Driver Information
Centre. In case a speed limit with
addon is available, a + symbol is
displayed in this area.
176Driving and operatingTrailer hitch
General information
Only use towing equipment that has
been approved for your vehicle.
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
The bulb outage detection function for trailer brake light cannot detect a
partial bulb outage. E.g. in case of
four bulbs with a power of 5 W each,
the function only detects lamp outage
when only a single 5 W lamp remains
or none remain.
Fitting of towing equipment could
cover the opening of the towing eye.
If this is the case, use the coupling ball bar for towing. Always keep the
coupling ball bar in the vehicle when
not in use.Driving characteristics and
towing tips
Before attaching a trailer, lubricate
the coupling ball. However, do not do
so if a stabiliser, which acts on the coupling ball, is being used to reduce
snaking movements.
For trailers with low driving stability
and caravan trailers with a permitted
gross vehicle weight of more than
1000 kg, a speed of 80 km/h must not be exceeded. The use of a stabiliser
is recommended.
If the trailer starts snaking, drive more slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 236.Trailer towing
Trailer loadsThe permissible trailer loads are
vehicle and engine-dependent
maximum values which must not be exceeded. The actual trailer load is
the difference between the actual
gross weight of the trailer and the
actual coupling socket load with the
trailer coupled.
The permissible trailer loads are
specified in the vehicle documents. In general, they are valid for gradients
up to max. 12%.
The permitted trailer loads apply up to
the specified incline and up to an
altitude of 1000 m above sea level.
Since engine power decreases as
altitude increases due to the air
becoming thinner, therefore reducing
climbing ability, the permissible gross train weight also decreases by 10%
for every 1000 m of additional
altitude. The gross train weight does
not have to be reduced when driving
on roads with slight inclines (less than
8%, e.g. motorways).
Driving and operating177The permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3 225.
Vertical coupling load
The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.
The maximum permissible vertical
coupling load (75 kg) is specified on
the towing equipment identification
plate and in the vehicle documents.
Always aim for the maximum load,
especially in the case of heavy
trailers. The vertical coupling load
should never fall below 25 kg.
Rear axle load
The permissible axle loads (see
identification plate or vehicle
documents) must not be exceeded.Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.
Stowage of coupling ball bar
The bag with the coupling ball bar is
stowed in the rear stowage
compartment on the floor.
Place the strap through the lashing
eye, wrap around twice and tighten
the strap to secure the bag.
Fitting the coupling ball bar
Disengage and fold down the socket. Remove the sealing plug from the
opening for the coupling ball bar and
stow it.
Driving and operating179Attach breakaway stopping cable to
eye.
Check that the coupling ball bar is
correctly installed
● Green marking on rotary knob must point towards green
marking on coupling ball bar.
● There must be no gap between the rotary handle and the
coupling ball bar.
● The coupling ball bar must be firmly engaged in the opening.
● The coupling ball bar must be locked and the key removed.9Warning
Towing a trailer is permitted only
when a coupling ball bar is fitted correctly. If the coupling ball bardoes not engage correctly, seekthe assistance of a workshop.
Dismounting the coupling ball bar
Open the protective flap and turn the
key to position c to unlock the
coupling ball bar.
Pull out rotary handle and turn
clockwise as far as it will go. Pull out coupling ball bar downwards.
Insert sealing plug in opening. Fold away socket.
