388 STARTING AND OPERATING
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the shift
lever is in the DRIVE position. For example, if you shift
the transmission into 3 (third gear), the transmission will
never shift above third gear, but will shift down into
second and first gear 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. Tapping the shift
lever to the left (-) (console shift) or the ERS (-) switch
Column Shift Lever

rent gear in the instrument cluster, and maintain that gear
as the top available gear. Once in ERS mode, tapping the
shift lever to the left (-) or right (+) (console shift) or the
ERS (-) or (+) switch (column shift) will change the top
available gear.
