Transmission

Electronic Range Select (ERS) Mode

ERS mode allows you to choose the top-gear limit of the transmission and the vehicle's speed while driving downhill or towing a trailer.

The vehicle has an electronic shift position indicator within the instrument panel cluster. When using the ERS mode a number will display next to the L, indicating the current gear that has been selected.

To use this feature:

1. Move the shift lever to L (Low).

2. Press the plus/minus button located on the shift lever, to increase or decrease the gear range available.

See Manual Mode on page 9‑25.
