Radio/cassette player 
with DIN fittings

Removal

1 Disconnect the battery negative lead.
2 Carefully prise out and remove the small
plastic trim panels at each side of the
radio/cassette player (see illustration).
3 Insert the removal tools into the holes
provided at each side of the unit, until they
lock into position. This will release the
securing clips (see illustration).
4 Using the tools, pull the unit forwards from
the housing, and disconnect the wiring
connectors and the aerial lead (see
illustration).

5 Withdraw the unit from the facia.
6 Note that some units may have a bracket
and rubber buffer fitted to the rear panel. If a
new unit is being fitted, transfer these
components to the new unit. The buffer sets
the depth of the unit in the housing, and
prevents the security cover fouling the
cassette during insertion and ejection. These
parts are available from dealers if they are not
fitted.

Refitting

7 To refit the unit, reconnect the wiring plugs
and the aerial lead, and push the unit into
position until the securing clips lock. Ensure
that the wiring harness and aerial lead are
routed so that they cannot rub against the unit
casing.
8 Refit the plastic covers to each side of the
unit, and reconnect the battery negative lead.
9 Where applicable, to activate the unit, enter
the security code in accordance with the
manufacturer’s instructions.

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.

Precautions

General precautions

4 The following precautions must

be

observed when carrying out work on a vehicle
equipped with an air bag.

a) Do not disconnect the battery with the

engine running.

b) Before carrying out any work in the vacinity

of the air bag, removal of any of the air bag
components, or any welding work on the
vehicle, de-activate the system as
described in the following sub-Section.

c) Do not attempt to test any of the air bag

system circuits using test meters or any
other test equipment.

d) If the air bag warning light comes on, or

any fault in the system is suspected,
consult a Peugeot dealer without delay.

diagnosis, or any dismantling of the
components.

Precautions to be taken when
handling an air bag

a) Transport the air bag by itself, bag

upward.

b) Do not put your arms around the air bag.
c) Carry the air bag close to the body, bag

outward.

d) Do not drop the air bag or expose it to

impacts.

e) Do not try to dismantle the air bag unit.
f) Do not connect any form of electrical

equipment to any part of the air bag circuit.

Precautions to be taken when storing
an air bag unit

a) Store the unit in a cupboard with the air

bag upward.

b) Do not expose the air bag to

temperatures above 80ºC.

c) Do not expose the air bag to flames.
d) Do not attempt to dispose of the air bag -

consult a Peugeot dealer.

e) Never refit an air bag which is known to

be faulty or damaged.

De-activation of air bag system

5 The system must be de-activated before
carrying out any work on the air bag
components or surrounding area.

a) Switch off the ignition.
b) Remove the ignition key.
c) Switch off all electrical equipment.
