Clutch, Gearbox, Transmission -> AM6 Gearbox Controls for Your Citroen C6 4 Door First Generation (2005-2012)

AM6 GEARBOX CONTROLS  
Engines: ES9A - DT17BTED4  
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 control has 5 positions:  
- Position "P": parking (locking and immobilisation of the vehicle).  
- Position "R": reverse gear.  
- Position "N": neutral.  
- Position "D" : drive (for use of the 6 gears in autoadaptive automatic operation).  
- Position "M": manual (this position allows the driver to select his gears in one-touch mode by  
pulling "M -" or pushing "M +" on the gear selector).  
NOTE: Only positions "P" or "N" authorise starting of the engine.  
In position "M", the selection is enabled by an electronic sensor located close to the gear  
selector:  
- The variation of flux necessary to affect the sensor cells is obtained by a magnet on the lever  
opposite the cells, provoking the changes of status.  
- The information on this is transmitted to the gearbox ECU.

NOTE: 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 normal programme, you have to press a second time on the sport or snow  
switch.
