Electronic Range Select (ERS) Operation
Six-Speed Transmission
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the trans-
mission is in DRIVE. For example, if you set the transmis-
sion gear limit to 4 (fourth gear), the transmission will not
shift above fourth gear, but will shift through the lower
gears normally.
Use of ERS (or TOW/HAUL mode) also enables an addi-
tional underdrive gear which is not normally used during
through-gear accelerations. This additional gear can im-
prove vehicle performance and cooling capability when
towing a trailer on certain grades. In ERS mode, gears 1
though 3 are underdrive gears, and ERS 4 is direct drive.
ERS 5 and 6 (Overdrive gears) are the same as the normal
fourth and fifth gears.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the gear selector is in the DRIVE
position, the transmission will operate automatically, shift-
ing between all available gears. Tapping the ERS (-) switch
(column shift) or tapping the gear selector to the left (-)
(console shift) will activate ERS mode, display the current
gear in the instrument cluster, and set that gear as the top
available gear. For example, if you are in DRIVE and are in
third (direct) gear, when you tap the gear selector/switch
one time in the (-) direction, the display will show 4 (ERS
4 is direct gear). Another tap down (-) will shift the
transmission down to ERS 3 (the added underdrive gear).
Once in ERS mode, tapping (-) or (+) will change the top
available gear.
