Range Change Procedure (Automatic Vehicles Only)

Neutral must be selected on the main transmission before requesting a range change and then select the appropriate gear following completion of the range change. During the range change the main transmission will be locked in neutral.

If neutral is not selected when a range change is requested then the request is denied and the driver will be advised to select neutral via the instrument cluster message center (if fitted).

The range change process can take up to one second to complete following a request being accepted.

There is a limit set on the maximum speed at which a range change can be achieved. The maximum speed for a high to low range change is 25 mph (40 km/h) for vehicles with automatic transmission, and 12 mph (20 km/h) for vehicles with manual transmission. The maximum speed for a low to high range change is 37 mph (60 km/h). If the vehicle speed is over the limit when a range change is selected then the request is denied and the instrument cluster message center (if fitted) will display a 'SLOW DOWN' message.
