Driving
Front parking sensors
In addition to the rear parking sensors, the
front parking sensors are triggered when an
obstacle is detected in front and the speed of
the vehicle is still below 6 mph (10 km/h).
The front parking sensors are interrupted if
the vehicle stops for more than three seconds
in forward gear, if no further obstacles are
detected or when the speed of the vehicle
exceeds 6 mph (10 km/h).
The sound from the speakers (front or
rear) indicates whether the obstacle is
in front or behind.

Deactivation / Activation of the
front and rear parking sensors
The system is deactivated in the
" Driving assistance " menu of the
touch screen.
 Press this button. The indicator
lamp in the button comes on.
Pressing this button again reactivates the function.
The indicator lamp in the button goes off.
The system will be deactivated
automatically if a trailer is being towed
or a bicycle carrier is fitted (vehicle
fitted with a towbar or bicycle carrier
recommended by PEUGEOT).
Operating fault
In the event of a malfunction of
the system, when reverse gear
is engaged this warning lamp is
displayed in the instrument panel and/
or a message appears, accompanied
by an audible signal (short beep).
Contact a PEUGEOT dealer or a qualified
workshop.
In bad weather or in winter, ensure
that the sensors are not covered with
mud, ice or snow. When reverse gear is
engaged, an audible signal (long beep)
indicates that the sensors may be dirty.
Certain sound sources (motorcycle,
lorry, pneumatic drill, etc.) may trigger
the audible signals of the parking
sensor system.
