Allow the clutch pedal to come back up to its high position.
Fill the brake fluid reservoir to the maximum of its capacity.
Open the bleed screw at «c».
Action the clutch pedal manually through its entire travel: 7 times
rapidly down and up.
The last time, keep the clutch pedal fully down.
Reclose the bleed screw, at «c».
If necessary, repeat the operation.
Top up the brake fluid to the MAX.level of the brake fluid reservoir.
Work the clutch vigorously 40 times
.
Start the engine.
Apply the handbrake.
Engage a gear.
Check that the clutch starts to engage at a dimension (X)greater than or equal to 45 mm
(the dimension (X)is
given as a guide).

GEARBOX
TRANSMISSION
AL4 GEARBOX CONTROLS
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 gearsin 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.

STEERING
CHECKING THE POWER STEERING ASSISTANCE PRESSURE
Preliminary operation.
Move aside the high pressure pipe (1).
Do up:
- The union [6]on the power steering electropump.
- The union [7]on the high pressure pipe (1).
- Tighten all the unions.
Fill the power steering reservoir 10 mmabove the max. level.
IMPERATIVE: Use new power steering fluid for both filling and topping-up the circuit.
Open the tap [5].
Start the engine and allow it to run for 5 seconds.
Stop the engine.
Move the steering several timesin each direction.
Check the steering fluid level and make sure that there are no leaks.
Checking the electropump pressure.
Start the engine.
Close the tap [5]for 5 seconds.
Open the tap [5].
Stop the engine.
At accelerated idle
(1200 to 1500rpm), the pressure should be 105 ± 5 bars.
If the electropump pressure is correct, check the valve sealing.

BRAKESBLEEDING AND FILLING THE BRAKING SYSTEM
Bleeding the braking circuit without the bleed apparatus.
NOTE:Two operators are necessary.
For each brake circuit:
- Apply the brake pedal to place the circuit under pressure.
- Couple a transparent tube on the bleed screw.
- Submerge the other end of the tube in a clean container.
- Open the bleed screw.
- Wait until the fluid flows out without air bubbles.
- Close the bleed screw.
NOTE:Recommence the process a second timeif that is necessary.
Check the level of the brake fluid
(between the «DANGER»level and
the «MAXI»level).
Fill if necessary with the the approved and recommended synthetic
brake fluid.Bleeding the secondary braking circuit.
WARNING: During the bleed operations: take care to maintain the
level of the brake fluid in the reservoir, keep it topped up.
NOTE:The bleed apparatus [1]is still connected on the brake fluid
reservoir (4).
Use the diagnostic tools [2]or [3].
Select the menu corresponding to the vehicle:
- ABSmenu
(according to equipment).- ESPmenu (according to equipment).
Follow the instructions of the diagnostic tool.
At the end of the bleed programme, check the level of the brake fluid,
top up if necessary.
Check the travel of the brake pedal: it must not be excessive. If it is,
restart the bleed procedure.
