system is an aid to driving which
does not replace the vigilance or
responsibility of the driver. Puncture
The service warning lamp
comes on in the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function screen locating
the wheel concerned.
Check the tyre pressures as soon as
possible. This check must be carried
out when the tyres are cold. The
STOP warning lamp
comes on in the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function screen locating
the wheel concerned.
Stop immediately, avoiding any sud-
den movement of the steering wheel
and the brakes.
Change the damaged wheel (punctured
o r v e r y d e fl a t e d t y r e ) , a n d h a v e t h e t y r e
pressure checked as soon as possible.
S e n s o r ( s ) n o t d e t e c t e d o r f a u l t y
The service warning lamp
comes on in the instrument
panel, accompanied by an
audible signal and a mes-
sage on the multifunction
screen locating the wheel
or wheels which are not detected or
indicating a fault in the system.
Have the faulty sensor(s) checked by
a CITROËN dealer. All repairs and changing of tyres
o n a w h e e l fi t t e d w i t h t h i s s y s t e m
must be carried out by a CITROËN
dealer.
If, when changing a tyre, you in-
stall a wheel which is not detected
b y y o u r v e h i c l e ( e x a m p l e : fi t t i n g
of snow tyres), you must have the
system reinitialised by a CITROËN
dealer.
This system does not avoid the
need to have the tyre pressures
checked regularly (refer to the
" T e c h n i c a l d a t a - § I d e n t i fi c a t i o n
markings" section) to ensure that
the optimum dynamic perform-
ance of the vehicle is maintained
and prevent premature wear of the
tyres, particularly in arduous driv-
ing conditions (heavy load, high
speed).
The tyre pressures must be
checked cold, at least once a
month. Remember to check the
pressure of the spare wheel.

netic signals on a frequency close

This message is also displayed
when one of the wheels is away
from the vehicle (being repaired) or
when one or more wheels without a

AIRBAGS

safety of the occupants (with the
e x c e p t i o n o f t h e r e a r c e n t r e p a s -
senger) in the event of violent col-
lisions. It supplements the action of
the force-limiting seat belts.
If a collision occurs, the electronic
detectors record and analyse the
front and side impacts sustained in
the impact detection zones:
- in the case of a serious impact,
the airbags are triggered instant-
ly and protect the occupants of
t h e v e h i c l e ( w i t h t h e e x c e p t i o n o f
the rear centre passenger); im-
mediately after the impact, the

e x i t o f t h e o c c u p a n t s ,
- in the case of a minor or rear impact or in certain roll-over
conditions, the airbags will not
be triggered; the seat belt alone
i s s u f fi c i e n t t o p r o v i d e o p t i m u m
protection in these situations.
The airbags do not operate when
the ignition is switched off.
This equipment will only operate
once. If a second impact occurs
(during the same or a subsequent
accident), the airbag will not operate.
Impact detection zones
A. Front impact zone.
B. Side impact zone.
Triggering of the airbag(s) is ac-
companied by a slight emission of
harmless smoke and a noise, due to
the activation of the pyrotechnic car-
tridge incorporated in the system.
This smoke is not harmful, but sen-
s i t i v e i n d i v i d u a l s m a y e x p e r i e n c e
slight irritation.
The noise of the detonation may
result in a slight loss of hearing for
a short time. Front airbags
System which protects the head and
chest of the driver and front passenger
in the event of a front impact.
The driver's airbag is incorporated
in the centre of the steering wheel;
the front passenger's airbag is incor-
porated in the dashboard above the
g l o v e b o x .
Activation
The airbags are triggered simultane-
ously, unless the passenger's front
airbag is deactivated, 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 di-
rected from the front to the rear of
the vehicle.

movement.

CHECKS
Unless otherwise indicated, check
these components in accordance
with the Warranty and Maintenance
Record and according to your engine.
Otherwise, have them checked by a
CITROËN dealer.
Battery The battery does not re-
quire any maintenance.
However, check that the
terminals are clean and
correctly tightened, particu-
larly in summer and winter.
When carrying out work on the bat-
tery, refer to the "Practical infor-
mation" section for details of the
precautions to be taken before dis-
connecting the battery and following
its reconnection.
Air filter and passenger compartment filter
Refer to the Warranty and
Maintenance Record for
details of the replacement
intervals for these compo-
nents.
Depending on the environment (e.g.
dusty atmosphere) and the use of
the vehicle (e.g. city driving), replace
them twice as often if necessary
(refer to the "Engines" section).

Complementary to the catalytic

tive contribution to the preservation
of air quality by the retaining of the
unburnt pollutant particles. Black
exhaust fumes are thus no longer
emitted.
After prolonged idling or driving at very
low speeds, you may occasionally no-
tice water vapour being emitted from
the exhaust when accelerating. This is
of no consequence to the running of
the vehicle or to the environment.
If there is risk of clogging, a message
appears on the multifunction screen,
accompanied by an audible signal
and lighting of the service warning
lamp.
This alert tells you that the particle
