Driving

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 Co󰀨ee 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 rst alert level, the driver is warned by
the message "Caution!", accompanied by an
audible signal.
After three rst-level alerts, the system triggers
a further alert with the message "Driving at
risk: Take a break", 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 following situations may interfere
with the operation of the system or
prevent it from working:
– lane markings absent, worn, hidden (snow,
mud) or multiple (roadworks);
– close to the vehicle ahead (lane markings
not detected);
– roads that are narrow, winding, etc.
Parking sensors
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids.
This system detects and signals the proximity of
obstacles (e.g. pedestrian, vehicle, tree, barrier)
using sensors located in the bumper.
Rear parking sensors
► Engage reverse gear to start the system
(conrmed by an audible signal).
The system is switched o󰀨 when reverse gear is
disengaged.
Audible assistance
The system signals the presence of obstacles
which are both within the sensors’ detection zone
and in the vehicle path dened by the direction of
the steering wheel.
The proximity information is given by an
intermittent audible signal, the frequency of
which increases as the vehicle approaches the
obstacle.
When the distance between the vehicle and
the obstacle becomes less than about thirty
centimetres, the audible signal becomes
continuous.
The sound emitted by the speaker (right or
left) indicates the side on which the obstacle is
located.
