limited. The distance of the image that
appears on the display differs from
the actual distance.
Guide lines
The vertical lines represent the
general direction of the vehicle and
the distance between the vertical
lines corresponds to the width of your vehicle without mirrors. The first
horizontal line represents a distance
of about 30 cm beyond the edge of
vehicle's rear bumper. The upper
horizontal lines represent distances
of about 1 and 2 metres beyond the
edge of your vehicle's rear bumper.
The crossing curves represent the
maximum turning circle.

Switching off
The camera is switched off when a
certain forward speed is exceeded or
if reverse gear is disengaged for
approx. 10 seconds.
System limitationsThe rear view camera may not
operate properly when:
● The surrounding is dark.
● The beam of headlights is shining
directly into the camera lenses.
● During nighttime driving.
● Weather limits visibility, such as fog, rain, or snow.● The camera lenses are blockedby snow, ice, slush, mud, dirt.Clean the lense, rinse with water,
and wipe with a soft cloth.
● The tailgate will be opened.
● The vehicle is towing an electrically connected trailer.
● The vehicle had a rear end accident.
● There are extreme temperature changes.
Lane departure warning
The lane departure warning system
observes the lane markings between
which the vehicle is driving via a front camera. The system detects lane
changes and warns the driver in the
event of an unintended lane change
via visual and acoustic signals.
Criteria for the detection of an
unintended lane change are:
● No operation of turn signals.
● No brake pedal operation.
● No active accelerator operation or speeding-up.
Driving and operating181Trailer hitch
General information
The factory-fitted towing equipment is
folded up under the rear bumper
fascia.
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. Only use
towing equipment that has been
approved for your vehicle.
To avoid vehicle damage, the power
tailgate cannot be operated with the
radio remote control when a trailer is
electrically connected.
The bulb outage detection function for trailer brake light cannot detect a
partial bulb outage, e.g. in case of four
times five watt bulbs, the function only detects lamp outage when only a
single five Watt 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.Driving characteristics and
towing tips
Before attaching a trailer, lubricate the coupling ball. However, do not do so if a stabiliser, which acts on thecoupling ball, is being used to reduce
snaking movements.
During trailer towing do not exceed a
speed of 80 km/h. A maximum speed
of 100 km/h is only appropriate if an
oscillation damper is used and the
permissible gross trailer weight does
not exceed the vehicle’s curb weight.
For trailers with low driving stability
and caravan trailers, the use of an
oscillation damper is strongly
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 3 239.Trailer towing
Trailer loads The 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 12%.
The permissible trailer load applies
up to the specified incline and at 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 metres of altitude. The gross train weight does not have to be reduced when driving on roads with
slight inclines (less than 8%, e.g.
motorways).
182Driving and operatingThe permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3 228.
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 of 60 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
When the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) may be exceeded by 60 kg , the gross vehicle weight rating
must not be exceeded. If the
permissible rear axle load is
exceeded, a maximum speed of
100 km/h applies.
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 on the rear floor cover in the
load compartment.
Place the strap through the rear right
lashing eye, wrap around twice and
tighten the strap to secure the bag.
Fitting the coupling ball bar
184Driving and operatingEye for break-away stopping cable
Attach 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.
Swivel the connecting socket
upwards.
Stow the coupling ball bar in the bag
and secure by fixing the strap through the rear right lashing eye. Wrap
around twice and tighten the strap to
secure the bag.

Service information In order to ensure economical and
safe vehicle operation and to
maintain the value of your vehicle, it
is of vital importance that all
maintenance work is carried out at the proper intervals as specified.
The detailed, up-to-date service
schedule for your vehicle is available
at the workshop.
Severe operating conditions exist if one or more of the following
circumstances occur frequently: Cold
starting, stop and go operation, e.g.
for taxis and police vehicles, trailer
operation, mountain driving, driving
on poor and sandy road surfaces,
increased air pollution, presence of
airborne sand and high dust content,
driving at high altitude and large
variations of temperature.
Under these severe operating
conditions, certain service work may
be required more frequently than the
regular service interval indicated inthe service display. Contact a
workshop for customised service
schedules.
