Deactivation
This warning lamp comes on
in the instrument panel when
the ignition is on and until the
airbag is reactivated.
To guarantee the safety of your
child, it is imperative that the pas-
senger airbag is deactivated when
you install a "rearwards-facing" child
seat on the front passenger seat.
Otherwise, the child would risk be-
ing seriously injured or killed if the
airbag were triggered. Reactivation
When you remove the child seat,
turn switch
1 to the "ON" position to
reactivate the airbag and so guaran-
tee the safety of your front passen-
ger in the event of an impact.
Operating fault

If this warning lamp comes
on in the instrument panel,
accompanied by an audible
warning and a message on

"rearwards-facing" child seat on
the front passenger seat.
Have it checked by a CITROËN
dealer.
Only the front passenger's airbag
can be deactivated:

 with the ignition off , insert the
key in the passenger airbag de-
activation switch 1 ,

the passenger compartment. Operation
It is triggered at the same time as the
corresponding side airbag in the event
of a serious side impact applied to all or
part of the side impact zone
B , perpen-
dicular to the longitudinal centreline of
the vehicle on a horizontal plane and
directed from the outside towards the
inside of the vehicle.
The curtain airbag infl ates between
the front or rear occupant of the ve-
hicle and the windows.
In the event of a minor impact or
bump on the side of the vehicle or
if the vehicle rolls over, the airbag
may not be triggered.
The airbag is not triggered in the

Dynamic emergency braking
In the event of a failure of the ve-
hicle’s main braking system or in
an exceptional situation (e.g. driver
taken ill, under instruction, etc) a
continuous pull on control A will stop
the vehicle.
The electronic stability programme
(ESP) provides stability during dy-
namic emergency braking.
If the dynamic emergency braking
malfunctions, one of the following
messages will be displayed on the
multifunction screen:
- "Parking brake faulty".
- "Parking control faulty". If a failure of the ESP sys-
tem is signalled by the ligh-
ting of this warning lamp,
then braking stability is not
guaranteed. In this event, stability
must be assured by the driver by
repeating alternate "pull release" ac-
tions on control A .
The dynamic emergency
braking must only be used in
exceptional circumstances.
