PEUGEOT 508 Handbook page 177

This driving aid system is designed to
improve safety when driving and is in no
circumstances a substitute for the use
of the interior rear view mirror and door
mirrors. It is the driver's responsibility to
constantly check the traffic, to assess the
relative distances and speeds of other
vehicles and to anticipate their movements
before deciding whether to change lane.
This system is a driving aid which cannot,
in any circumstances, replace the need for
vigilance on the part of the driver.
Activation/Deactivation
The function is activated and
deactivated in the Driving/Vehicle
menu of the touch screen.
The state of the system is memorised when
switching off the ignition.
The system is automatically deactivated
when towing with a towing device
approved by PEUGEOT.
Operation
Sensors fitted in the front and rear bumpers
monitor the blind spots.
The alert is given by an orange warning lamp
coming on in the relevant door mirror, as soon
as a vehicle – car, lorry, bicycle – is detected.
The following conditions must be met for this:

- the speed of the vehicle must be between
19 and 87 mph (30 and 140 km/h) (versions
with Park Assist or Full Park Assist),
- you overtake a vehicle with a speed
difference of less than 6 mph (10 km/h),
- a vehicle overtakes you with a speed
difference of less than 16 mph (25 km/h),
- the traffic is flowing normally,
- overtaking a vehicle over a certain period
of time and the vehicle being overtaken

curved road,
