With the vehicle stationary, the instrument
panel is turned on when the door is opened
and various vehicle-related information is
displayed. The engaged gear is however not
displayed. The C 510 AMT gearboxes pump is
activated to pressurise the circuit and allow
the system to be activated when there is a
starting request.
Measures Before Key On:
With key-Off (vehicle is stationary with elec-
trical services turned off), you can press the
gearbox panel buttons with or without brake
pedal pressed. The system will not carry out
any activation after pressing; therefore the
gear engaged before the key off remains un-
changed.
Key On (+15):
With the vehicle stationary and the ignition
key in the ignition position (ignition-operated
electrical services activated), the instrument
panel should display the gear engaged, give
an indication of the operating mode (auto-
matic = AUTO or manual = NO DISPLAY) (the
vehicle always starts up in last mode).
With the brake pedal pressed
, it is possible
to engage First, Neutral and Reverse gears.
Without pressing the brake pedal
, any gear
change request made is not implemented by
the system.
