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.

From the diagnostic tool menus, select:
«DIAGNOSIS»
MA type piloted manual gearbox.
Actuator test.
Gearbox actuator test.

Engaging of «N», without using a diagnostic tool.
In this configuration, the gearbox actuator is blocked, gear engaged.
NOTE:This recovery solution is to be used solely in a case where the
attempt to make the gearbox actuator engage b via the diagnostic toolhas failed.

(supplier:SIEMENS). A gearbox actuator with two electric motors (supplier:SACHS).
A clutch actuator with one electric motor (supplier:SACHS).
A gearbox input speed sensor.
The piloted manual gearbox has no gear control cable and no clutch cable.Changes of gear and clutching/declutching are activated by the gearbox
actuator and the clutch actuator.
Lubrication.
Oil capacity : 2 ± 0,15 litres.
Checking of oil level : No oil level check.(*)Lubrication intervals : Lubricated «for life».
(*)= Only a visual check of the sealing at each engine oil change interval.
