INSTRUMENTS, DESCRIPTION AND OPERATION, Description.
Malfunction Indicator Lamp (MIL)
The MIL is located in the lower left hand corner of the instrument pack, below the fuel gauge. Transmission related
faults which may affect the vehicle emissions output will illuminate the MIL.
The MIL is illuminated by the ECM on receipt of a relevant fault message from the EAT ECU on the CAN. The nature
of the fault can be diagnosed using TestBook which reads fault codes stored in the ECU memory.
Transmission Status Display
The transmission status display is located on the right hand side of the instrument pack, below the tachometer. The
display shows the selector lever position and in the case of manual (Steptronic) mode, the selected gear. The selector
lever position and gear selected displays are illuminated in a green colour when active.
