4.4.3 Display method
Basically the GEAR POSITION is shown by turning ON the LED that corresponds with the selected
position. In 1st gear, LED '1' is ON, in 2nd gear, LED '2' is on etc..
The selected direction is shown with the COLOUR of the LED :
RED
indicates
NEUTRAL
GREEN
indicates
FORWARD
YELLOW
indicates
REVERSE
Additionally LED 'N' (RED) is ON while the transmission is in neutral.
The position shown is ALWAYS the selected SHIFT LEVER position. Most of the time, the actual
transmission position will be the same as the shown one, and in that case that's all there is.
However if, because of an active protection or because of some internally generated delay, there is a
discrepancy between transmission position and shift lever position, a 2nd LED will indicate the
transmission position (colour indicates direction).
To let the driver know the difference between both indications, the transmission LED blinks while the
shift lever LED stays ON all the time.
While this may seem a bit confusing at first, it's very easy to understand the shown information in
reality.
example :
Driving in 4th gear forward at high speed
LED 4 - GREEN
⇒
When the driver is making a downshift, but
due to a too high speed the EGS will protect
the transmission and will not allow the
requested downshift. Thus the transmission
will stay in 4th gear forward, while the
shiftlever is in 3rd gear forward
LED 3 - GREEN &
⇒
LED 4 - blinking GREEN
