Electronic Range Select (ERS)Operation
The Electronic Range Select (ERS) shift control allows
you to move the shift lever left (-) or right (+) when the
shift lever is in the DRIVE position, allowing you to limit
the highest available gear. For example, if the driver
shifts the transmission into ERS 3 (third gear), the trans-
mission will never shift above third gear, but can shift
down to 2 (second) or 1 (first), when needed.
NOTE:
•
If you pull and hold (not tap) the shift lever to the left

When in the DRIVE position, the first tap to the left (-),
will shift down one gear and will display that gear. For

transmission will downshift to 4th gear and the display
will show 4. Another tap to the left (-) will shift the
transmission into 3rd gear.
5.7L Engine
On vehicles equipped with 5.7L engines, use of ERS (or
TOW/HAUL mode) also enables an additional underdrive
gear which is not normally used during through-gear
accelerations. This additional gear improves vehicle perfor-
mance and cooling capability when towing a trailer on
certain grades. ERS 1,2, and 3 are underdrive gears; ERS 4
is direct drive. ERS 5 (Overdrive) is the same as the normal
4th gear. When in the DRIVE position in 1st through 4th
gear, the first tap to the left (-), will display the ERS
designation for the current gear (the transmission will not
