Lane departure warning
The lane departure warning system
observes the lane markings between
which the vehicle is driving via a front camera located at the top of thewindscreen. The system warns the
driver in the event of an unintendend
lane departure via visual and acoustic signals.
There is no lane departure warning
when the turn lights are operated and during 20 seconds after turn lights
have been switched off.9 Warning
This system is a driving aid that
cannot, in any circumstances,
replace the need for vigilance on
the part of the driver.
Activation
After ignition is switched on, the lane
departure warning system is
activated. If the system is activated,
the LED in the button ½ is not
illuminated. To activate the system
when the system is deactivated,
press ½.
The system is only operable at
vehicle speeds above 37 mph and if
lane markings are available.
When the system recognises an
unintended lane departure, the
control indicator ) flashes yellow.
Simultaneously a chime sound is
activated.
Deactivation
To deactivate the system, press andhold ½. The LED in the button is
illuminated and ½ illuminates yellow in
the instrument cluster.
Driving and operating193● winding or hilly roads
● road edges
● sudden lighting changes
● adverse environmental conditions, e.g. heavy rain or
snow
● vehicle modifications, e.g. tyres
Switch off the system if the system is
disturbed by tar marks, shadows,
road cracks, temporary or
construction lane markings, or other
road imperfections.9 Warning
Always keep your attention on the
road and maintain proper vehicle
position within the lane, otherwise
vehicle damage, injury or death
could occur.
Lane keep assist does not
continuously steer the vehicle.
The system may not keep the
vehicle in the lane or give an alert,
even if a lane marking is detected.
The steering of the lane keep
assist may not be sufficient to
avoid a lane departure.
The system may not detect hands-
off driving due to external
influences like road condition and
surface and weather. The driver has full responsibility to control the vehicle and is always required to
keep the hands on the steering
wheel while driving.
Using the system while towing a
trailer or on slippery roads could
cause loss of control of the vehicle
and a crash. Switch the system off.
Driver alert
The driver alert system monitores the driving time and the vigilance of the
driver. Monitoring the vigilance of the
driver is based on the trajectory
variations of the vehicle compared to
the lane markings.
9 Warning
The system cannot replace the
need for vigilance on the part of
the driver. Taking a break is
recommended as soon as feeling tired or at least every two hours.
Do not take the steering wheel
when feeling tired.
Activation or Deactivation
The system can be activated or
deactivated in the vehicle
personalisation 3 107.
The state of the system stays in
memory when the ignition is switched
off.
Driving time alert The driver gets notified by a pop-up
reminder symbol € in the Driver
Information Centre simultaneously with an acoustic alert if the driver has
not taken a break after 2 hours of
driving at a speed above 40 mph. The alert is repeated hourly until the
vehicle is stopped, no matter how
vehicle speed evolves.
Driving and operating205Trailer hitch
General information
Only use towing equipment that has
been approved for your vehicle. If
using non-factory fitted towing
equipment, deactivation of the hands- free tailgate operation may be
required 3 29.
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 light outage
when only a single 5 W light remains
or none remain.
Trailers equipped with LED lights are
not suitable for the wiring harness of
this trailer hitch.
Fitting of towing equipment could
cover the opening of the towing eye.
If this is the case use the coupling ballbar for towing. Always keep the
coupling ball bar in the vehicle to have it on hand if needed.
Driving characteristics and towing tips
Before attaching a trailer, lubricatethe 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 3 266.
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 inclines 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 m of altitude. The
gross train weight does not have to be
206Driving and operatingreduced 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
3 256.
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 (70 kg) is specified on
the towing equipment identification
plate and in the vehicle documents.
Always aim for the maximum vertical
coupling 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.
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 operating207Checking the tensioning of the
coupling ball bar
● Red marking on rotary knob must
point towards green marking on
coupling ball bar.
● The gap between the rotary knob
and the coupling ball bar must be approx. 6 mm.
● Remove the cover from the lock of the rotary knob and verify
whether the rotary knob is
locked. If the rotary knob cannot be turned, it is locked.
Otherwise, the coupling ball bar must be tensioned before being inserted:
● Unlock coupling ball bar by turning key to position c.● Pull out rotary knob and turn
clockwise as far as it will go.
Inserting the coupling ball bar
208Driving and operatingInsert 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. Fold away socket.
Trailer stability assist
If the system detects snaking
movements, engine power is reduced
and the vehicle / trailer combination is
