Driving and operating165Activation or DeactivationThe system can be activated or
deactivated in the vehicle
personalisation 3 96.
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.
The counting of driving time alert is
reset when the ignition has been
switched off for a few minutes.
Driver drowsiness detection The system monitors the driver's level
of vigilance. A camera in the
windscreen detects variations in
trajectory compared to the lanemarkings. This system is particularly
suited for a speed higher than
40 mph.
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 40 mph for
a few minutes.System limitations
The system may not operate properly
when:
● dazzle caused by headlights of an oncoming vehicles, low sun,
reflections on damp roads
● driving on winding, hilly or narrow
roads
● driving in the dark
● weather limits visibility, such as fog, rain, or snow
● the camera is blocked by snow, ice, slush, mud, dirt
● the windscreen is damaged 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
● multiple lane markings due to roadworks
● sudden lighting changes

Driving and operating167
The use of B20 or B30 fuel meetingstandard EN16709 is possible.
However, this use, even occasional, requires strict application of the
special servicing conditions referred
to as "arduous conditions".
For further information, contact a
workshop.
Caution
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).
Notice
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 may
affect 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.

168Driving and operating9Danger
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.
The fuel filler flap can only be opened
if the vehicle is unlocked. Release the
fuel filler flap by pushing the flap.
Petrol and diesel refuelling 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.

Performing work9 Warning
Only perform engine compartment
checks when the ignition is off.
The cooling fan may start
operating even if the ignition is off.
9 Danger
The ignition system uses
extremely high voltage. Do not
touch.
Bonnet
Opening
Open the driver's door.
Pull the lever and return it to its
original position.
Move the safety catch sideways to the
left vehicle side and open the bonnet.
Secure the bonnet support.
Closing
Before closing the bonnet, press the
support into the holder.
Lower the bonnet and let it fall into the latch from a low height (20-25 cm).
Check that the bonnet is engaged.
Caution
Do not press the bonnet into the
latch to avoid dents.

Vehicle care179Caution
Only washer fluid with a sufficient
antifreeze concentration provides
protection at low temperatures or
a sudden drop in temperature.
Washer fluid 3 219.
Brakes In the event of minimum thickness of
the brake lining, a squealing noise
sounds during braking.
Continued driving is possible but
have the brake lining replaced as
soon as possible.
Once new brake linings are installed,
do not brake unnecessarily hard for
the first few journeys.
Brake fluid
9 Warning
Brake fluid is poisonous and
corrosive. Avoid contact with eyes,
skin, fabrics and painted surfaces.
The brake fluid level must be betweenthe MIN and MAX marks.
If fluid level is below MIN seek the
assistance of a workshop.
Brake fluid 3 219.
Vehicle battery
The vehicle battery is maintenance-
free provided that the driving profile
allows sufficient charging of the
battery. Short-distance-driving and
frequent engine starts can discharge
the battery. Avoid the use of
unnecessary electrical consumers.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
Laying up the vehicle for more than
four weeks can lead to battery
discharge. Disconnect the clamp from the negative terminal of the vehicle
battery.
Ensure the ignition is switched off
before connecting or disconnecting
the vehicle battery.

Replacing the vehicle battery Notice
Any deviation from the instructions
given in this section may lead to temporary deactivation or
disturbance of the stop-start system.

Vehicle care181● See the Owner's Manual forfurther information.
● Explosive gas may be present in the vicinity of the vehicle battery.
Power saving mode
This mode deactivates electrical
consumers to avoid excessive
discharging of the vehicle battery.
These consumers, such as the
infotainment system, windscreen
wipers, low beam headlights,
courtesy light, etc. can be used for a
total maximum time of about
40 minutes after ignition is switched
off.
Deactivating power saving mode
Power saving mode is deactivated
automatically when the engine is
restarted. Run the engine for a
sufficient charge:
● for less than 10 minutes to use the consumers for approx.
5 minutes
● for more than 10 minutes to use the consumers for up to approx.
30 minutesDiesel fuel system bleeding
If the tank has been run dry, the diesel fuel system must be bled. Switch on
the ignition three times for
15 seconds at a time. Then crank the
engine for a maximum of
40 seconds. Repeat this process after
no less than 5 seconds. If the engine fails to start, seek the assistance of a
workshop.
