2014.5 Citroen C ZERO wheel

58
Under-inflation detection
System which continuously and automatically
checks the pressures of the four tyres after
switching on the ignition.
A pressure sensor is located in the valve of
each tyre.
The system triggers an alert if a drop in
pressure is detected in one or more tyres,
compared to the reference pressure registered
in the system. This reference pressure must be
reinitialised every time the tyre pressures are
adjusted or a wheel changed.
The system operates on condition that sensor
identifiers have first been memorised in the
system by a CITROËN dealer or a qualified
workshop.
You can memorise two sets of tyres
(for example: wheels with "standard" tyres and
wheels with "winter" tyres).The tyre under-inflation detection
system is an aid to driving which does
not replace the need for vigilance on
the part of the driver. This system does not avoid the need to
check the tyre pressures regularly and
before a long journey.
Driving with under-inflated tyres
adversely affects road holding,
extends braking distances and causes
premature tyre wear, particularly under
arduous conditions (vehicle loaded,
high speed, long journey).
Driving with under-inflated tyres
increases fuel consumption. The tyre pressures for your vehicle can
be found on the tyre pressure label (see
the "Identification markings" section).
The tyre pressures must be checked
when the tyres cold (vehicle stopped
for 1 hour or after driving for less then
6 miles (10 km) at moderate speed).
Other wise, add 0.3 bar to the values
indicated on the label.

Before reinitialising the system, ensure
that the pressures in the four tyres are
suitable for the conditions of use of the
vehicle and as specified on the tyre
pressure label.
The under-inflation detection system
cannot warn of an incorrect pressure at
the time of reinitialisation.
The loss of pressure detected does not
always lead to visible deformation of the
tyre. Do not rely on just a visual check.
The alert is maintained until the
reference pressure is reinitialised after
the inflation, repair or replacement of
the tyres concerned. In the event of
the repair or replacement of tyres, the
sensor identifiers must be registered in
the system by a CITROËN dealer or a
qualified workshop.

dealer or a qualified workshop. Any tyre repair or replacement on a
wheel fitted with this system must be
carried out by a CITROËN dealer or a
qualified workshop.
If you fit the second set of tyres
memorised in the system, a fault will
be signalled until the second set is
selected in the configuration menu.

Managing sets of wheels
and tyres
Selection of the other set of wheels and tyres
is is done via the instrument panel screen, with
the ignition on and the vehicle stationary.
After fitting the new set of wheels and
tyres, you should check and adjust the
tyre pressures to the values specified
on the tyre pressure label (see the
"Identification markings" section). The system automatically reinitialises
the reference pressure based on the
pressure in the new set (the under-
inflation detection warning lamp flashes
during the operation).
If you have had a second set of wheels and
tyres registered by a CITROËN dealer or a
qualified workshop, every time you change the
set of wheels (fitting a set of winter tyres, for
example), you must select the set you have just
fitted in the configuration menu.

The symbol going off in the instrument panel
indicates the reactivation of the ASR and ESP
systems.
The anti-slip regulation (also known as Traction
Control) optimises traction to limit wheel spin,
by acting on the brakes of the driving wheels
and on the engine.
The electronic stability programme acts on the
brake of one or more wheels and on the engine
to keep the vehicle on the trajectory required
by the driver, within the limits of the laws of
physics.
This is indicated by flashing of this
symbol in the instrument panel. The ASR /ESP systems offer should not
encourage the driver to take extra risks
or drive at high speed.
The correct functioning of these
systems depends on observation of
the manufacturer's recommendations
regarding the wheels (tyres and rims),
the braking components, the electronic
components and the assembly
and repair procedures used by the
CITROËN dealer network.
After an impact, have these systems
checked by a CITROËN dealer or a
qualified workshop.
Operating fault
The display of this message in
the instrument panel indicates
a malfunction of these
systems.
Contact a CITROËN dealer or a qualified
workshop to have the ASR /ESP systems checked.
Excessive wheel spin may damage your

Airbags
The airbags have been designed to contribute
towards improving the safety of the occupants
in the event of violent collisions. They
supplement the action of the force-limiting seat
belts.
In this case, the electronic detectors record and
analyse the front and side impacts suffered in
the impact detection zones:
-
i
n the event of a serious impact, the
airbags are deployed instantaneously
and contribute towards protecting the
occupants of the vehicle; immediately after
the impact, the airbags deflate rapidly
so that they do not hinder the visibility of
the occupants or their possible exit from
the


vehicle,
-

i
n the event of a minor impact or rear
impact and in certain roll-over conditions,
the airbags may not be deployed; the seat
belt alone contributes towards providing
your protection in these situations.
The airbags do not operate when the
ignition is off.
This equipment only operates once. If a
second impact occurs (during the same
or a subsequent accident), the airbag
will not be deployed again. The deployment of one or more airbags
is accompanied by a slight discharge
of smoke and a noise, due to the
activation of the pyrotechnic cartridge
incorporated in the system.
This smoke is not harmful, but sensitive
individuals may experience some
irritation.
The noise of the detonation related to
the deployment of one or more airbags
may result in a slight loss of hearing for
a short time.

in the event of a serious front impact applied
to all or part of the front impact zone A , in
the longitudinal centreline of the vehicle on a
horizontal plane and directed from the front to
the rear of the vehicle.
The front airbag inflates between the front
occupant of the vehicle and the dashboard to
cushion their for ward movement. System which protects the head and chest of
the driver and front passenger in the event of a
