labels or other objects; they may hamper
correct operation of the system.
Distraction detection
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids.
Depending on version, the function consists of
either the "Coffee Break Alert" system alone or
combined with the "Driver Attention Warning"
system.
These systems are in no way designed
to keep the driver awake or to prevent
the driver from falling asleep at the wheel.
It is the driver's responsibility to stop if feeling
tired.
Take a break if you are feeling tired or at least
every 2 hours.
Activation/Deactivation
The settings are changed via the
Driving/Vehicle touch screen
menu.
The status of the function is saved when the
ignition is switched off.
Coffee Break Alert
The system triggers an alert when it
detects that the driver has not taken a
160
break after two hours of driving at a speed above
43 mph (70 km/h).
This alert is issued via the display of a message
encouraging the driver to take a break,
accompanied by an audible signal.
If the driver does not follow this advice, the alert
is repeated hourly until the vehicle is stopped.
The system resets itself if one of the following
conditions is met:
– With the engine running, the vehicle has been
stationary for more than 15 minutes.
– The ignition has been switched off for a few
minutes.
– The driver's seat belt is unfastened and their
door is opened.

As soon as the speed of the vehicle
drops below 43 mph (70 km/h), the
system goes into standby.
Driving time starts being counted again once
the speed reaches above 43 mph (70 km/h).
Driver Attention Warning
Depending on version, the Coffee Break Alert
system may be combined with the Driver
Attention Warning system.
The system assesses the driver's level of
alertness, fatigue and distraction by
identifying trajectory changes in relation to the
lane markings.
To do this, the system uses a camera, placed on
the upper part of the windscreen.
This system is particularly suited to fast roads
(speed higher than 43 mph (70 km/h)).
At a first alert level, the driver is warned by the
message "Be vigilant!", accompanied by an
audible signal.
After three first-level alerts, the system triggers
a further alert with the message "Dangerous
driving: take a break", accompanied by a more
pronounced audible signal.
The following situations may interfere
with the operation of the system or
prevent it from working:
– poor visibility conditions (e.g. insufficient
road lighting, snowfall, heavy rain, dense fog).
– dazzle (e.g. headlamps of an oncoming
vehicle, low sun, reflections on a wet road
