RECOMMENDATIONS PRECAUTIONS: MA PILOTED MANUAL GEARBOX
Operations on electrical components.Do not disconnect:
The battery when the engine is running.
The ECU with the ignition switched on.
The clutch and gearbox actuators with the ignition switched on.
When carrying out electrical checks: The battery must be correctly charged.
Never use a voltage source higher than 16V.
Never use a lamp to supply an actuator directly.
Before disconnecting connector, check: The condition of the various contacts (for deformation, corrosion, etc).
The presence and the status of the mechanical unlocking.
Driving the vehicle.
IMPERATIVE:
Never move the vehicle with the ignition switched off.
Never push the vehicle to attempt to start it
(impossible with a piloted
manual gearbox).
Towing.
Conditions for towing.
It is necessary to lift the front of the vehicle to tow it, after having
positioned the gear lever in neutral. If there is a gearbox fault or
malfunction, the vehicle can remain immobilised depending on theseriousness of the fault.
If a gear is engaged,the conditions for immobilisation of the
vehicle are:
Combustion engine stopped (the engine should not be started).
The clutch is open (clutched).
In these conditions are met, you can lift the front of the vehicle to tow it.
If it should not be possibe to lift the front of the vehicle, there are
ways to unblock it:
Engage «N», using a diagnostic tool.
Engage «N», without using a diagnostic tool.

Precautions to be taken.
Towing.
The front of the vehicle must be raised in order to be towed.
If the front of the vehicle cannot be raised:
IMPERATIVE: Put gear lever in position «N».
Do not add any oil.
Do not exceed
30 mphover a distance of 30 milesof maximum.
Driving.
Never drive with the ignition switched off.
Never push the vehicle to try to start it
(impossible with an automatic gearbox).
NOTE:The automatic gearbox is only lubricated when the engine is
running.
Repairs on electrical components.
Do not disconnect:
The battery when the engine is running.
The ECU when the ignition is switched on.
Before reconnecting a switch,check: The condition of the various contacts (for deformation, corrosion etc).
The presence and condition of the mechanical locking.
When performing electrical checks: The battery should be correctly charged.
Never use a voltage source higher than 16V.
Never use a test lamp.

In passenger compartment (continued).
The information is transmitted to the gearbox ECU.
NOTE:The vehicle is equipped with the «shift lock»«P».
Two switches placed on the gear control gate permit the driver to choose one of the following
three driving programmes:

Normal programme: Operates as the default programme (eco law, autoadaptive mode).
Sport programme (a): Permits a more dynamic, sporty performance.
Snow programme (b): Facilitates starting and adhesion on slippery surfaces.
To return to the normal programme, press a second time on the sport switch or snow switch.

ELECTRICAL
SYSTEM
CHARGING CIRCUIT ALTERNATOR WITH MONOFUNCTION REGULATOR
Checking the alternator output.
Connect as shown in the diagram opposite, using an ammeter (A), a voltmeter (V),
and a rheostat
(R)or a Volt/Ammeter/Rheostat combination.
Referring to the vehicle’s equipment specification
(see table opposite), adjust the
engine speed and rheostat charge to obtain
U = 13.5 V.
Reminder:The excitation energising current will flow through the warning lamp;
check that the warning lamp comes on when the ignition is switched on. It shouldgo out when the engine has started
(accelerate slightly).
Checking the voltage regulator.
Set the rheostat to zero and disconnect all the electrical consumers.
Display
3000alternator rpm. If U alternator is > 14.7 V, the regulator is faulty.
Note:These tests should be performed with the engine hot and the battery fully
charged.
Method of reading the alternator speed.
Fit a reflecting shim on the pulley of the alternator.
Adjust a stroboscope to the frequency equivalent to the control speed.
(e.g. 2000 rpm = 2000/60 = 83 Hz).
Adjust the engine speed so that the shim appears fixed.

AIRCONAIRCON
AIR CONDITIONING SYSTEM R 134.a
Testing procedure
Conditions inside the vehicle.
Positions of the air conditioning controls:
Maximum cold.
Maximum blower power.
Air distribution on
«ventilation»with the air vents open.
Position the air inlet flap to outside air.
WARNING:For RFTA (1), disconnect the air inlet motor connector, first
ensuring that it is in the outside air position.
(1) RFTA= Fully automatic air conditioning.
Test procedure.When all these conditions are met, proceed in the following order:
Measure the temperature in the workshop approx. one metre in front of
the vehicle’s air inlet grille.
Start the engine
(without the air conditioning, or the blower, operating)and wait for the cooling fan slow speed to trigger (should the engine tem
perature not rise sufficiently, it is permissable to increase the engine
speed to 2000 rpm)
.
Once it is sufficiently hot in the engine compartment, return the engine
to idle and commence the test.Switch on the air conditioning and adjust the engine speed to
2500 rpm.
In an ambient temperature of 40°C, the engine speed will be brought
down to 2000 rpm, in order for the pressure safety threshold to cut off the
compressor.
For further temperatures/pressures: see Tables and Graphs on following
pages
221, 222 and 226.
After
3 minutesof operation, note down the following 3 parameters:
The temperature of the blown air coming out of the 2 central air vents
(take the average).
The high pressure, via the intermediary of the clickfit union (at the
pressure reducer inlet).
The low pressure, via the intermediary of the clickfit union (at the pressure
reducer outlet).NOTE:The low and high pressures are absolute pressures.
When measuring the blown air temperatures, avoid any contact between
the thermocouple and the air vents.
