12 V battery
The Stop & Start system requires a
12 V battery of specific technology and
specification.
All work must be carried out only by a
PEUGEOT
dealer or a qualified workshop
Tyre under-inflation detection
This system alerts the driver if one or more tyres
suffer a drop in pressure.
The alert is raised when the vehicle is moving,
not when stationary.
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.
It takes into account the last values stored
during the reinitialisation request. It is therefore
essential that the tyre pressure is correct during
the operation. This operation is the driver’s
responsibility.
The tyre under-inflation detection cannot, in any circumstances, 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.
Checking tyre pressures
This check should be done monthly
when the tyres are "cold" (vehicle stopped for
1 hour or after a journey of less than 6 miles
(10

km) at moderate speeds).
Otherwise, add 0.3 bar to the pressures
shown on the label.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Under-inflation alert
This is signalled by the fixed illumination of this warning lamp, accompanied by an
audible signal and, depending on equipment, the
display of a message.
►

Reduce speed immediately
, avoid excessive
steering movements and avoid sudden braking.
►

Stop the vehicle as soon as it is safe to do
so.
The loss of pressure detected may not always cause visible deformation of the
tyre.
Do not rely on just a visual check.
►

Using a compressor
, such as the one in
the temporary puncture repair kit, check the
pressures of all four tyres when cold.
►

If it is not possible to carry out this check
immediately

, drive carefully at reduced speed.
►

In the event of a puncture, use the
temporary puncture repair kit or the spare wheel
(depending on equipment).
Driving too slowly may not ensure
optimum monitoring.
The alert is not immediately triggered in the
event of a sudden loss of pressure or tyre
blow-out. This is because analysis of the
values read by the wheel's speed sensors
can take several minutes.
The alert may be delayed at speeds below
25 mph (40 km/h), or when adopting a sporty
driving mode.
The alert is kept active until the system is reinitialised.
Reinitialisation
► The system must be reinitialised after any
adjustment to the pressure of one or more tyres,
and after changing one or more wheels.
Before reinitialising the system, make
sure that the pressures of the four tyres
are correct for the conditions of use of the
vehicle and conform to the values written on
the tyre pressure label.
Check the pressures of the four tyres before
performing the reinitialisation.
The system does not advise if a pressure is
incorrect at the time of reinitialisation.
With the vehicle stationary, the
system is reinitialised via
the Driving/Vehicle touch screen menu.
Malfunction
In the event of a malfunction, these
warning lamps light up on the
instrument panel.

Event data recorders
Event data recorders
Electronic control units are installed in your
vehicle. Control units process data which is
received by vehicle sensors, for example, or
which they generate themselves or exchange
amongst themselves. Some control units are
necessary for the safe functioning of your
vehicle, others assist you while you drive (driver
assistance systems), while others provide
comfort or infotainment functions.
The following contains general information about
data processing in the vehicle. You will find
additional information as to which specific data is
uploaded, stored and passed on to third parties
and for what purpose in your vehicle under
the key word Data Protection closely linked
to the references for the affected functional
characteristics in the relevant owner's manual
or in the general terms of sale. These are also
available online.
Operating data in the
vehicle
Control units process data for operation of the
vehicle.
This data includes, for example:
–
vehicle status information (e.g. speed,
movement delay

, lateral acceleration, wheel
rotation rate, "seat belts fastened" display)
–

ambient conditions (e.g. temperature, rain
sensor

, distance sensor) As a rule such data is transient and is not stored
for longer than an operational cycle, and only
processed on board the vehicle itself. Often
control units include data storage (including the
vehicle key). This is used to allow information
to be documented temporarily or permanently
on vehicle condition, component stress,
maintenance requirements and technical events
and errors.
Depending on technical equipment levels, the
data stored is as follows:
–

system component operating states (e.g. fill
level, tyre pressure, battery status)
–

faults and defects in important system
components (e.g. lights, brakes)
–

system reactions in special driving situations
(e.g. triggering of an airbag, actuation of the
stability control systems)
–

information on events damaging the vehicle
–

for electric vehicles the amount of charge in
the high-voltage battery
, estimated range
In special cases (e.g. if the vehicle has detected
a malfunction), it may be necessary to save data
that would otherwise just be volatile.
When you use services (e.g. repairs,
maintenance), the operating data saved can
be read together with the vehicle identification
number and used where necessary. Staff
working for the service network (e.g. garages,
manufacturers) or third parties (e.g. breakdown
services) can read the data from the vehicle.
The same applies to warranty work and quality
assurance measures. Data is generally read via the OBD (On-Board
Diagnostics) port prescribed by law in the
vehicle. The operating data read documents the
technical condition of the vehicle or individual
components and assists with fault diagnosis,
compliance with warranty obligations and quality
improvement. This data, in particular information
on component stress, technical events, operator
errors and other faults, is transmitted to the
manufacturer where appropriate, together
with the vehicle identification number. The
manufacturer is also subject to product liability.
The manufacturer potentially also uses operating
data from vehicles for product recalls. This data
can also be used to check customer warranty
and guarantee claims.
Fault memories in the vehicle can be reset by a
service company when carrying out servicing or
repairs or at your request.
Comfort and infotainment
functions
Comfort settings and custom settings can be
stored in the vehicle and changed or reset at any
time.
Depending on the equipment level in question,
these include
–

seat and steering wheel position settings
–


chassis and air conditioning settings
–


custom settings such as interior lighting
You can input your own data in the infotainment
functions for your vehicle as part of the selected
features.
Depending on the equipment level in question,
these include
– multimedia data such as music, videos or
photos for playback in an integrated multimedia
system
– address book data for use with an integrated
hands-free system or an integrated navigation
system
– input destinations
– data on the use of online services
This data for comfort and infotainment functions
can be stored locally in the vehicle or be kept on
a device that you have connected to the vehicle
(e.g. a smartphone, USB stick or MP3 player).
Data that you have input yourself can be deleted
at any time.
This data can only be transmitted out of the
vehicle at your request, particularly when using
online services in accordance with the settings
selected by you.
Smartphone integration,
e.g. Android Auto or Apple
CarPlay
If your vehicle is equipped accordingly, you can
connect your smartphone or another mobile
device to the vehicle so that you can control it
via the controls integrated in the vehicle. The
smartphone image and sound can be output
