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 the selection
of the desired top gear. For example, if the driver shifts
the transmission into 3 (third gear), the transmission will
never shift above third gear, but can shift down to 2
(second) or 1 (first), when needed.
When in the DRIVE position, the first tap to the left (-),
will show the current gear. For example, if you are in
DRIVE and are in 3rd gear, when you tap the shift lever
one time to the left (-), the display will show 3. Another
tap to the left (-) will shift the transmission into 2nd gear.
If you are in DRIVE and are in 5th gear, the first tap to the
left (-) will display 5. Another tap to the left (-) will shift
the transmission into 4th gear.
On vehicles equipped with 4.7L or 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 im-
proves vehicle performance and cooling capability when
towing a trailer on certain grades. In ERS mode (on all
transmissions), 1st through 3rd gear are underdrive
gears, and 4th gear is direct drive. ERS 5th gear (Over-
drive) is the same as the normal 4th gear.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid.
