The rear pneumatic suspension enhances driving
comfort by maintaining a constant body height what-
ever the vehicle load.
OPERATION
- If there is an increase in vehicle load, a sinking of
the rear of the vehicle is detected and the pneumatic
springs inflate in order to compensate for the extra
weight.
- If there is an decrease in load, a rising of the rear of
the vehicle is detected and so the pneumatic springs
deflate to return the vehicle to its nominal height.
- If the vehicle has been unused for a long period, the
pneumatic springs may inflate if necessary when you
unlock or open a door, so as to return the vehicle to
its nominal height.
Note : If you do not reactivate the system manually,
the automatic correction will be activated as soon as
