Driving and operating185Complete attention is always required
while driving, and you should be
ready to take action and apply the
brakes and / or steer the vehicle to
avoid crashes.
We recommend to deactivate the
system in the vehicle personalisation
in the following cases:
● when towing a trailer or caravan
● when carrying long objects on roof bars or a roof rack
● when the vehicle is being towed with the engine running
● when a spare wheel is fitted that is smaller than the other wheels
● before using an automatic car wash with the engine running
● before placing the vehicle on a rolling road in a workshop
● if the windscreen has been damaged close to the camera
● if the front bumper has been damaged
● if the brake lamps are not workingFault
In case the system requires a service, m is illuminated in the instrument
cluster, a message is displayed in the Driver Information Centre and an
audible signal is given.
If the system does not work as it
should do, vehicle messages are
displayed in the Driver Information
Centre.
Vehicle messages 3 117.
Front pedestrian protection Front pedestrian protection may help
to avoid or reduce the harm caused
by front-end crashes with pedestrians when driving forward.
The system uses the front camera in
the windscreen to detect a pedestrian
directly ahead in your path.
Front pedestrian protection can
detect and alert to pedestrians in a
forward gear at speeds between
5 km/h and 60 km/h.
During nighttime driving, system
performance is limited.9 Danger
Front pedestrian braking does not
provide an alert or automatically
brake the vehicle, unless it detects
a pedestrian.
The system may not detect
pedestrians, including children,
when the pedestrian is not directly ahead, not fully visible, not
standing upright, or when part of a
group.
Front pedestrian protection includes:
● detecting front pedestrian ahead● front pedestrian alert
Front pedestrian protection is
activated together with forward
collision alert.
Forward collision alert 3 181.
Detecting front pedestrian ahead
A pedestrian ahead up to a distance
of approx. 40 m is indicated by a
symbol in the instrument cluster.
Driving and operating193DeactivationThe current park assist manoeuvre is
cancelled via the button to return to
the previous screen in the Info
Display. To deactivate the system
completely, press ¼ in the centre
console.
The system is deactivated
automatically:
● if the ignition is switched off
● if stalling the engine
● if no manoeuvre is started within 5 minutes of selection of the type
of manoeuvre
● after a prolonged stop of the vehicle during a manoeuvre
● if the Electronic Stability Control is triggered
● if the speed of the vehicle exceeds the stated limit
● when the driver interrupts movement of the steering wheel
● after seven manoeuvres for entering a perpendicular parking
slot (a manoeuvre consists of
one rear move or one forward
move)● after ten manoeuvres for entering
or exiting a parallel parking slot
● on opening a door or the load compartment
● if one of the front wheels encounters an obstacle
● parking manoeuvre successfully ended
Deactivation by the driver or by the
system during manoeuvring will be
indicated on the display. Additionally,
an acoustic signal sounds.
The system is switched off
automatically when towing an
electrically connected trailer, bicycle
carrier, etc.
Contact your dealer to switch off the
system for a prolonged period.
Fault
In the event of a fault, a message is
displayed in the Colour Info Display, accompanied by an acoustic signal.
In the event of a fault in the power
steering, C illuminates and a
message is displayed in the Driver
Information Centre.9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Special attention must be paid to
low obstacles which can damage
the lower part of the bumper.
Caution
Performance of the system can be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
system can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles in the vicinity
(e.g. off-road vehicles, mini vans,
vans). Object identification and correct distance indication in the
upper part of these vehicles
cannot be guaranteed.
Driving and operating205The 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 thedriver, 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.● dazzle caused by headlamps of oncoming 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 roads
206Driving and operatingFuel
Fuel for petrol engines The petrol engines are compatible
with bio-fuels that conform to current
and future European standards and
and can be obtained from filling
stations:
Petrol that meets the EN228
standard, mixed with a biofuel
meeting the EN15376 standard.
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 meetingstandard EN16709 is possible in your
Diesel engines. However, this use,
even occasional, requires strict
application of the special servicing
conditions referred to as "Arduous
conditions".
For more information, contact a
dealer or a qualified workshop.
Driving and operating207Caution
The use of any other type of (bio)
fuel (vegetable or animal oils, pure
or diluted, domestic fuel etc.) is
strictly prohibited (risk of damage
to the engine and fuel system).
Note
The only Diesel additives authorised for use are those that meet the
B715000 standard.
Low temperature operation
At temperatures below 0 °C, some
diesel products with biodiesel blends may clog, freeze or gel, which mayaffect the fuel supply system. Starting
and engine operation may not work
properly. Make sure to fill winter
grade diesel fuel at ambient
temperatures below 0 °C.
Arctic grade diesel fuel can be used
in extreme cold temperatures below
-20 °C. Using this fuel grade in warm
or hot climates is not recommended
and may cause engine stalling, poor starting or damage on the fuel
injection system.
Refuelling9 Danger
Before refuelling, switch off
ignition and any external heaters
with combustion chambers.
Follow the operating and safety
instructions of the filling station
when refuelling.
9 Danger
Fuel is flammable and explosive.
No smoking. No naked flames or
sparks.
If you can smell fuel in your
vehicle, have the cause of this
remedied immediately by a
workshop.
A label with symbols at the fuel filler
flap is indicating the allowed fuel
types. In Europe the pump nozzles of the filling stations are marked with
these symbols. Refuel only the
allowed fuel type.
Caution
In case of misfuelling, do not
switch on ignition.
Fuel filler flap is located at left rear
side of vehicle.
If the vehicle is equipped with an
electronic key system, the fuel filler
flap can only be opened if the vehicle
is unlocked. Depending on the
version, release the fuel filler flap by
pushing the flap or pulling at the right bottom corner.
208Driving and operatingPetrol and diesel refuelling
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 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 to have
it on hand if needed.
Driving and operating209Driving 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 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 3 266.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 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
3 259.
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.
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
212Driving and operating1. Connect the trailer plug to thesocket and fasten the breakaway
stopping cable to the eye on the
carrier.
2. Attach the trailer.
Type C
1. Remove the safety splint.
2. Pull the lever and open the towing
ring.
3. Attach the trailer, close the towing
ring and fix the splint.
4. Connect the trailer plug to the socket and attach the breakaway
stopping cable to the eye on the
carrier.
Trailer stability assist If the system detects snaking
movements, engine power is reduced
and the vehicle / trailer combination is
selectively braked until the snaking
ceases. While system is working keep
steering wheel as still as possible.
Trailer stability assist is a function of
the Electronic Stability Control 3 166.
