System limitations
The system may not operate properly
when:
● vehicle speed is below 60 km/h● driving on winding or hilly roads
● driving in the dark
● weather limits visibility, such as fog, rain, or snow
● the camera is blocked by snow, ice, slush, mud, dirt, windscreen
damage or affected by foreign
items, e.g. stickers
● the sun is shining directly into the
camera lens
● close vehicles ahead
● banked roads
● road edges
● roads with poor lane markings
● sudden lighting changes
Driver alert
The driver alert system monitores the driving time and the vigilance of the
driver. Monitoring the vigilance of the
202Driving and operatingdriver 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 2 hours. Do
not take the steering wheel when
feeling tired.
Activation or Deactivation
The system can be activated or
deactivated in the vehicle
personalisation 3 124.
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 Y 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 65 km/h. The
alert is repeated hourly until the
vehicle is stopped, no matter how
vehicle speed evolves.
The counting of driving time alert is
reset if one of the following conditions
is met:
● The vehicle has been stationary for more than 15 minutes with theengine running.
● The ignition has been switched off for a few minutes.
● The driver's seat belt has been unfastened and the driver's door
is open.
Note
If the vehicle speed drops below 65 km/h, the system is paused. The
driving time is counted again once
the speed is above 65 km/h.
Driver drowsiness detection
The system monitors the driver's level
of vigilance. A camera at the top of the
windscreen detects variations in
trajectory compared to the lane
markings. This system is particularly
suited to fast roads (speed higher
than 65 km/h).If the trajectory of the vehicle
suggests a certain level of
drowsiness or inattention by the
driver, the system triggers the first
level of alert. The driver is notified by
a message and an audible signal is
given.
After three first level alerts, the
system triggers a new alert with a
message, accompanied by a more
pronounced audible signal.
In certain driving conditions (poor
road surface or strong winds), the
system may give alerts independent of the driver's level of vigilance.
The driver drowsiness detection is
reinitialised when the ignition has
been switched off for a few minutes or the speed remains below 65 km/h for
a few minutes.
System limitationsIn the following situations, the system
may not operate properly or even not
operate at all:
● poor visibility caused by inadequate lighting of the
roadway, falling snow, heavy
rain, dense fog etc.
Driving and operating203● dazzle caused by headlamps ofoncoming vehicles, low sun,
reflections on damp roads,
leaving a tunnel, alternating
shade and light etc.
● windscreen area in front of the camera covered by dirt, snow,
stickers etc.
● no lane markings detected or multiple lane markings due to
roadworks
● close vehicles ahead
● winding roads or narrow roadsFuel
Fuel for diesel engines The Diesel engines are compatible
with bio-fuels that conform to current and future European standards and
and can be obtained from filling
stations:
Diesel fuel that meets standard
EN590 mixed with a biofuel that
meets standard EN14214 (possibly
containing up to 7% Fatty Acid Methyl
Ester)
Diesel fuel that meets standard
EN16734 mixed with a biofuel that
meets standard EN14214 (possibly
containing up to 10% Fatty Acid
Methyl Ester)
Paraffinic Diesel fuel that meets
standard EN15940 mixed with a
biofuel that meets standard
EN14214 (possibly containing up to
7% Fatty Acid Methyl Ester).
The use of B20 or B30 fuel meeting standard EN16709 is possible.
However, this use, even occasional, requires strict application of the
special servicing conditions referred
to as "Arduous conditions".
Driving and operating205version, release the fuel filler flap by
pushing the flap or pulling at the right bottom corner.
Depending on the version, place the
key in the lock and unlock the cap.
To open, turn the cap slowly
anticlockwise.
The fuel filler cap can be attached to
the hook on the fuel filler flap.
Place the nozzle in straight position to the filler neck and press with slight
force to insert.
To refuel, switch on pump nozzle.
After the automatic cut-off, the tank can be topped up by operating the
pump nozzle a maximum of two more
times.Caution
Wipe off any overflowing fuel
immediately.
To close, turn the fuel filler cap
clockwise until it clicks.
Close the flap and allow it to engage.
Fuel filler cap
Only use genuine fuel filler caps.
Diesel-engined vehicles have special fuel filler caps.
Trailer hitch
General information
Only use towing equipment that has
been approved for the 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.
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.
206Driving and operatingFor 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.
If the outside temperature exceeds
37 °C, reduce the load on the trailer
to protect the engine of the vehicle.
At high outside temperatures it is
recommended to leave the engine
running for one or two minutes after
having stopped the vehicle in order to
faciliate cooling.
Adjust tyre pressure to the value
specified for full load 3 271.
Towing a trailer increases the braking
distance of the vehicle. To limit the
heating of the brakes, it is
recommended to use the braking
effect of the engine.By driving uphill, the temperature of
the coolant is increased. To reduce
heating, drive at a reduced speed and
pay attention to the coolant
temperature. If the control indicator
2 of the engine coolant temperature
gauge illuminates, stop the vehicle
and switch off engine as soon as
possible.
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 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 airbecoming 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
3 264.
When distributing the loads in the trailer, heavy objects should be
placed as close as possible to the
axle.
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 is specified on the
towing equipment identification plate
and in the vehicle documents.
