164Driving and operating● 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.If the driver is active, no warning will
be issued.
Activation
The lane departure warning system isactivated by pressing  ½. The system
is switched on when the LED in the
button is not illuminated.
The system is only operable at
vehicle speeds above 37 mph and if
lane markings are available.
When the system recognises an
unintended lane change, the control
indicator  ) flashes yellow.
Simultaneously a chime sound is
activated.
Deactivation
The system is deactivated by
pressing  ½, the LED in the button
illuminates.
At speeds below 37 mph the system
is inoperable.
Fault
In the event of a fault,  F
appears in the instrument panel,
accompanied by a display message.
Contact a dealer or a qualified
workshop to have the system
checked.
The lane departure warning system
may not operate properly when:
● The windscreen is not clean.
● There are adverse environmental
conditions like heavy rain, snow,
direct sunlight or shadows. 

Driving and operating169715/2007 (in the version respectively
applicable), taking into consideration
the vehicle weight in running order, as
specified by the regulation.
The figures are provided only for the
purpose of comparison between different vehicle variants and mustnot be taken as a guarantee for the
actual fuel consumption of a
particular vehicle. Additional
equipment may result in higher
results than the stated consumption and CO 2 figures. Furthermore, fuel
consumption is dependent on personal driving style as well as road
and traffic conditions.Trailer 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 onlydetects 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 the
coupling ball, is being used to reduce snaking movements.
During trailer towing do not exceed a speed of 50 mph. A maximum speed
of 60 mph 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  3 228. 

170Driving and operatingTrailer towingTrailer 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 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).The permissible gross train weight
must not be exceeded. This weight is
specified on the identification plate
3  217.
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
60 mph 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. 

172Driving and operatingInserting the coupling ball bar
Insert the tensioned coupling ball bar
in the opening and push firmly
upwards until it audibly engages.
The rotary handle snaps back into its
original position resting against the
coupling ball bar without a gap.
9 Warning
Do not touch rotary handle during
insertion.
Lock the coupling ball bar by turning
the key to position  e. Remove the key
and close the protective flap.
Eye 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.

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.
