PRECAUTIONS TO BE TAKEN : AM6 AUTOMATIC GEARBOX
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 70 km/h (45 mph)over a distance of 100 km (60 miles)
maximum.
Driving.
Never drive with the ignition switched off.
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.
Repairs on mechanical components.
Never place the gearbox on the ground without protection.
Do not use the unions on the gearbox as handles for moving the
gearbox.
It is imperative
that the converter retaining peg should be in place
when removing the gearbox.
It is imperativeto use the centring pegs to couple the gearbox on the
engine.
Remove the converter retaining peg before coupling the gearbox on
the engine.

GEARBOX
TRANSMISSION
AM6 GEARBOX CONTROLSNOTE:The vehicle is equipped with «shift lock». It is necessary to switch on the ignition and
press the brake pedal to release the selection lever from position "P".
The switch "a"positioned on the gear control panel allows the driver to choose one of the
following 3 driving programmes:
- Normal programme:The normal programme operates in the absence of any other selection
being made (auto-adaptive mode ; eco law).
- Sport programme:The sport programme permits a more dynamic driving style, with greater
performances and acceleration.
- Snow programme:The snow programme facilitates moving off and traction on ground that
has limited adhesion.
To revert to the normalprogramme, you have to press a second timeon the sportor snow
switch.

AM6 GEARBOX CONTROLS: «SHIFT LOCK» FUNCTIONIMPERATIVE: Respect the safety and cleanliness requirements, with reference to the brochure:
«Recommendations-Precautions».
The «shift lock»is a system that locks the gear selection lever in position «P».
Unlocking the «SHIFT LOCK»(normal operation).
Switch on the ignition.
Press the brake pedal and keep it pressed.
Move the gear selection lever out of position «P».
Unlocking the «SHIFT LOCK» (with an operating fault).
Should it be impossible to unlock the «shift lock»with the «Normal operation»method.
The fault may originate from one of the following components:
- «Shift lock».
- Gear lever position switch.
- Automatic gearbox ECU.
- Electrical harness.
- Battery voltage.
Operations to be performed.
Unclip the cover (1).
Unlock the «shift lock»by pressing at "a"with the aid of a screwdriver (screwdriver with a minimum length of
150 mm).
Move the gear selection lever out of position "P".
