Removing-refitting
- Disconnect the negative battery lead, then
remove the sound insulation shield follow­
ing the instructions in the previous para­
graphs.
1. Disconnect the electrical connections (1)
at the fuel filter and the supply and return
pipes (2) at the reservoir and the supply
pipe to the pump, then loosen the nuts (3)
fixing the fuel filter mounting. Lift up the
filter and disconnect the electrical connec­
tion (4) for the water in the diesel sensor.
- Release the power assisted steering fluid
supply pipe from the reservoir to the pump
from the retaining band.
2. Disconnect the pipe (1) connected to the
vacuum reservoir and the pipe (2) con­
nected to the vacuum intake pipe from the
solenoid valve. Disconnect the electrical
connector (3), then undo the fixing bolts
(4) and remove the solenoid valve.
VACUUM RESERVOIR
Removing-refitting
- Disconnect the negative battery lead, then
remove the sound insulation shield and the
fuel filter, following the instructions in the
previous paragraphs.
- Release the power assisted steering fluid
supply pipe from the reservoir to the pump
from the retaining band.
3. Disconnect the pipe (1) connected to the
vacuum reservoir and the pipe (2) con­
nected to the vacuum intake pipe from the
solenoid valve. Disconnect the electrical
connector (3), then undo the fixing bolts
(4) and remove the bracket, complete with
solenoid valve, for the throttle casing

PROTECTION AND SAFETY DEVICES
All the vehicle supply lines were designed taking into account the most up-to-date directives in terms of
safety and protection, especially to prevent fires.
There are 2 types of protection:
- active protection, aims to reduce the causes of faults "at source"
- passive protection, aims to limit the effects of a fault as much as possible
The first category includes a carefully designed wiring layout with wires positioned and carefully anchored
on tracks that are repaired and protected if necessary.
The cables connected to the alternator and the motor were modified for this reason by adding protective
caps etc. A strengthened sheath was also introduced for some of the more exposed sections of wiring.
The passive protection includes all interventions to reduce faults due to high current (overload, short cir­
cuit).
All system fuses were rated based on the nominal absorbtion of the loads activated at the same time, to
ensure intervention in cases of a clear short circuit.
The introduction of a box containing 4 maxifuses with other fuses connected on the outside means all
the supplies can be protected except for the cable that connects the battery to the starter motor and the
cable that connects the starter motor to the recharging alternator. These cables are therefore protected by a
strengthened supplementary sheath.

WARNINGS
Anti-theft protection
The radio comes with a theft protection system comprising of a segret 4 digit code.
The protection system makes the rdaio inoperable if it is removed from the facia as a result of a theft. See
the following pages to activate the antitheft device
CODE card
The radio identity document shows the model, serial number and secret code.
The serial number is the same as the number stamped on the set frame
If the set is lost, the CODE card facilitates search investigations and speeds up claim settlement by insurers
due to the ownership document.

A

If the antitheft protection is active and the radio is disconnected from the car battery, the radio is
still protected electronically
It may only be operated again by entering a special code.
Display
If the set is disconnected from the voltage supply, the display figures flash when it is reconnected.
The flashing figures are a reminder that the clock must be reset as described below.
Extended function field (EXP key)
The EXPERT control level allows the user to use a range of functions beginning with the base control yet
without losing an overall view.
Operation with mobile phone (PHONE)
The radio is designed for connection to a mobile phone handsfree system (using the PHONE IN input).
The radio sound is deactivated while the mobile phone is in operation.
PHONE appears on the display.
