Alarm



System which protects and provides a deterrent
against theft and break-ins.
It provides the following types of monitoring:
Exterior perimeter

The alarm is triggered if anyone tries to open a
door, the boot or the bonnet.
Interior volumetric
The system checks for any variation in volume in
the passenger compartment.
The alarm is triggered if anyone breaks a
window, enters the passenger compartment or
moves inside the vehicle.
For vehicles that are fitted with it, interior
volumetric monitoring is incompatible
with programmed thermal preconditioning.
Anti-tilt
(On GTi version.)
The system checks for any change in the attitude
of the vehicle.

Malfunctions
Depending on the vehicle’s equipment:In the event of a system malfunction, this
warning lamp flashes on the instrument

ART/STOP" button.
The Stop & Start system requires a 12 V battery of specific technology and
specification.
All work concerning the battery must be
carried out only by a PEUGEOT dealer or a
qualified workshop.
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.

markings, refer to the corresponding section.
