Under-inflation detection
This system automatically checks the tyre pressures while driving.
It compares the information given by the wheel
speed sensors with reference values, which
must be reinitialised every time the tyre
pressures are adjusted or a wheel changed.
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one or
more tyres.
Under-inflation detection does not
replace the need for vigilance on the part
of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel), especially before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high
speed, long journey):
–

worsens road-holding.
–


lengthens braking distances.
–


causes premature wear of the tyres.
–


increases energy consumption.
The inflation pressures defined for the vehicle can be found on the tyre pressure
label.
For more information on the Identification
markings, refer to the corresponding section.

–

dazzle (headlamps of an oncoming vehicle,
low sun, reflections on a damp road, leaving a
tunnel, alternating shade and light, etc.),
–


radar obstructed (mud, frost, snow
,
condensation, etc.).
In these situations, detection performance
may be reduced.
Malfunction
In the event of a cruise control
malfunction, dashes are displayed instead
of the cruise control speed setting.
This warning lamp comes on, accompanied by a warning message and
an audible signal, to indicate a system
malfunction.
Have the system checked by a PEUGEOT
dealer or a qualified workshop.

Active Safety Brake with Distance Alert and
Intelligent emergency
braking assistance
Refer to the General recommendations on the
use of driving and manoeuvring aids .


This system:
–
warns the driver that their vehicle is at risk of
collision with the vehicle in front.
–

reduces the vehicle's speed to avoid a
collision or limit its severity

.
This system is comprised of three functions:
–

Distance Alert.
–


Intelligent emergency braking assistance.
–


Active Safety Brake (automatic emergency
braking).


The vehicle has a multifunction camera located
at the top of the windscreen and, depending on
version, a radar located in the front bumper.
This system does not avoid the need for vigilance on the part of the driver.
This system is designed to assist the driver
and improve road safety.
It is the driver's responsibility to continuously
monitor traffic conditions in accordance with
applicable driving regulations.
As soon as the system detects a potential obstacle, it prepares the braking
circuit in case automatic braking is needed.
This may cause a slight noise and a slight
sensation of deceleration.
Deactivation / Activation
By default, the system is automatically activated
at every engine start.
