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.

GEARBOX
TRANSMISSION
AL4 AUTOMATIC GEARBOX
In passenger compartment.The gear selector is guided by the shape of the stepped gate and by a retaining spring which
pulls it to the left hand side.
The gear selector control has
5 positions:
Position
«P»: Park (locking and immobilisation of the vehicle).
Position «R»:Reverse gear.
Position «N»: Neutral.
Position «D»: Drive (use of the 4 gears in their autoadaptive automatic function).
Position «M»: Manual (this position lets the driver select his own gears in sequential mode
by pulling the gear selector to «M-»or pushing it to «M+»).
NOTE:Only the positions «P»or «N»authorise the starting of the engine.
In position
«M», selection is by an electronic sensor located close to the gear lever.
The variation of flux necessary to the movement of the sensor cells is obtained by a magnet
located on the lever itself. This enables the change of status.
