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.

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.
