● banked roads
● road edges
● roads with poor lane markings
● sudden lighting changes
Driver alert9 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.
Page 167 of 253

Driving and operating165Activation or DeactivationThe system can be activated or
deactivated in the vehicle
personalisation 3 95.
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 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 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
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 limitations
The system may not operate properly
when:
● dazzle caused by headlamps 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

166Driving 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.
Use fuel with the recommended
octane rating. A lower octane rating
can reduce engine power and torque
and slightly increases fuel
consumption.
Caution
Use of fuel with a lower octane
rating than the lowest possible
rating could lead to uncontrolled combustion and engine damage.
The engine-specific requirements
regarding octane rating are given in
the engine data overview 3 226. A
country-specific label at the fuel filler
flap can supersede the requirement.
Fuel for diesel engines The diesel engines are compatiblewith bio-fuels that conform to currentand future European standards 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).
