General

1 Some models in the range are fitted with an
anti-theft alarm system as standard equipment.
The alarm is automatically armed and disarmed
using the remote central locking transmitter
(where applicable). When the system is
activated, the alarm indicator light, located on
the facia, will flash continuously. In addition to
the alarm function, the system also
incorporates an engine immobiliser.
2 Additionally, certain petrol engine models
are fitted with a coded engine immobiliser
device, operated by a key pad in the centre
console.

Anti-theft alarm system

Early models

3 Note that if the doors are operated using
the key, the alarm will not be armed or
disarmed (as applicable). Locking the doors
with the central locking remote transmitter is
the only means of activating the alarm system.
4 The alarm system protects the doors and
boot or tailgate, as applicable.
5 Should the alarm system become faulty, the
vehicle should be taken to a Peugeot dealer
for examination.

Later models

6 Note that if the doors are operated using
the key, the alarm will not be armed or
disarmed (as applicable). If for some reason
the remote central locking transmitter fails
whilst the alarm is armed, the vehicle must be
unlocked using the key. In this case, the alarm
system will activate, and must be disarmed
using the master switch (see paragraph 8).
7 The alarm system has switches on the
bonnet, tailgate and each of the doors. It also
has ultrasonic sensing, which detects
movement inside the vehicle, via sensors
mounted on either side of the vehicle interior. If
required, the ultrasonic sensing facility can be
switched off, whilst retaining the switched side
of the system. To switch off the ultrasonic
sensing, with the ignition switch off, depress
the alarm switch (mounted on the right of the
steering column) until the alarm indicator light
on the facia is continuously lit. Now, when the
doors are locked using the remote central
locking transmitter, and the alarm is armed,
only the switched side of the alarm system is
operational (and the alarm indicator light will
revert to its flashing mode). This facility is
useful, as it allows you to leave the
windows/sunroof open, and still arm the alarm.
If the windows/sunroof are left open with the
ultrasonic sensing not switched off, the alarm
may be falsely triggered by a gust of wind.
8 To deactivate the complete alarm system, a
master switch is provided in the engine
compartment, behind the left-hand headlight.
The switch is operated by a dedicated key,
and is protected by a plastic cover.
9 Should the alarm system become faulty, the
vehicle should be taken to a Peugeot dealer
for examination.

Coded engine immobiliser

10 This device cuts out the engine
management system, and prevents the engine
from being started unless a confidential code
is keyed into the pad located in the centre
console.
11 The code can be chosen by the owner,
and full details are given in the vehicle
handbook.
12 When the ignition is turned on, if the green
light on the key pad is illuminated, the system
is not working, and the engine can be started
normally. If the red light is illuminated, the
system is working (the engine cannot be
started, and the alarm will sound if starting is
attempted).
13 To de-activate the system, enter the
correct code, which should be confirmed by
four flashes from the green light, and four
beeps. The red light should go out, and the
engine can them be started.
14 If the wrong code is entered, the red light
will stay on, and the engine cannot be started.

Disconnecting the battery

Early models

15 If the battery has been disconnected,
when it is reconnected, the alarm will be
activated.
16 The alarm must be de-activated using the
remote central locking transmitter.

Later models

17 The following precautions should be
observed when disconnecting and
reconnecting the battery leads on a vehicle
equipped with an alarm system.
18 Before disconnecting the battery, de-
activate the alarm siren, using the dedicated
key.
19 When reconnecting the battery, as soon
as the battery is connected, the alarm is
automatically activated. Use the remote
transmitter to turn off the alarm, then activate
the alarm siren using the dedicated key.

24 Air bag system - general

information, precautions and
system de-activation

General information

1 A driver’s side air bag is fitted as standard
equipment on later models, and is an option
on all other models. The air bag is fitted in the
steering wheel centre pad.
2 The system is armed only when the ignition
is switched on, however, a reserve power
source maintains a power supply to the
system in the event of a break in the main
electrical supply. The system is activated by a

“g” sensor (deceleration sensor), and is
controlled by an electronic control unit which
is integral with the steering wheel.
3 The air bag is inflated by a gas generator,
which forces the bag out from its location in
the steering wheel.

Refitting

18 Refitting is a reversal of removal, bearing
in mind the following points.
19 Before refitting the steering column
shrouds and the air bag unit, check that the
wiring harness is routed correctly by moving
the steering wheel to check that the wiring is
not trapped.
20 Refit the steering wheel (see Chapter 10).
21 Refit the air bag as described previously
in this Section, but do not activate the air bag
at this stage.
22 On completion, move the steering column
to its fully raised position, then check that the
clearance between the rear face of the
steering wheel and the front faces of the
steering column shrouds is 8.0 mm. If the
clearance is not as specified, proceed as
follows.

a) Working in the driver’s footwell, unclip the

carpet trim panel from under the facia for
access to the steering column pinch-bolt.

b) Loosen the pinch-bolt, then slide the

steering shaft as necessary to give the
specified clearance between the steering
wheel and the shrouds.

c) Tighten the pinch-bolt, and refit the trim

panel.
