Gear Shift Position
The highlighted letter shown in the instrument panel indicates the gear shift position; D for drive, N for neutral, and R for reverse. See Fig., item 12. If none of the positions are highlighted, a failure mode has occurred and could be due to a communication problem with the transmission.

Drive Modes
When standard automatic transmission mode is used, the current gear position appears next to the D indicator, as shown in Fig.. When manual transmission mode is used, the indicator changes to M with the target gear position next to it; for example M5 5. To the right of the manual indicator, the actual gear position appears in blue.
When the transmission mode is changed by the driver on the transmission multifunction control, a message appears briefly in the tachometer. The message reads either 'performance' or 'economy.' See Fig..

Engine Brake
During engine braking, the gear position indicator changes to 2, representing the target gear. The actual gear position appears to the right in blue. See Fig..
When the engine brake is active, a white indicator activates in the instrument panel with the requested level of braking (low, medium, or high) in text to the right. The additional braking level text is only visible on vehicles equipped with varying brake levels.
When the engine brake engages, the indicator and text turn green. See Fig.. While the engine brake is engaged, the driver can adjust the engine brake level using the transmission multifunction control on the right of the steering wheel.
