GEARBOX
TRANSMISSION
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.

RECOMMENDATIONS PRECAUTIONS: AL4 AUTOMATIC GEARBOX
Engines: KFV NFU RFN RHZ
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.

BRAKESBLEEDING THE BRAKESXSARA PICASSO
Tools.Bleeding equipment of type «LURO» or similar.IMPERATIVE: For bleeding the secondary circuit, use ELIT, LEXIA or PROXIA diagnostic tools.
Draining.
Drain the brake fluid reservoir as empty as possible using a syringe.
Disconnect the brake fluid warning lamp connector.Retrieve the brake fluid reservoir from its supply pipes by pulling upwards.
Finish emptying the reservoir of brake fluid.
Clean the brake fluid reservoir.
Refit the brake fluid reservoir.
Reconnect the brake fluid warning lamp connector.
Filling.Refill the reservoir with brake fluid.WARNING:Use only the recommended hydraulic fluids.
Bleeding.
NOTE:Two technicians are required.
IMPERATIVE:During bleed operations, ensure that the level of brake fluid is maintained in the
reservoir and top it up, use only new brake fluid.
Bleed each wheel cylinder, proceeding in the following order:
Rear right hand wheel.
Front left hand wheel.
Rear left hand wheel.
Front right hand wheel.

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.
