Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear. For example, if
you shift the transmission into 4 (fourth gear), the
transmission will not shift above fourth gear, but will
shift through the lower gears normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the shift lever is in the DRIVE
position, the transmission will operate automatically,
shifting between all available gears. Moving the shift
lever to the ERS position (beside DRIVE) will activate
ERS mode, display the current gear in the instrument
cluster, and maintain that gear as the top available gear.
Once in ERS mode, moving the shift lever forward (-) or
rearward (+) will change the top available gear.
To exit ERS mode, simply return the shift lever to the
DRIVE position.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing a collision or
personal injury.
