transmission will downshift to 4th gear and the display
will show 4. Another tap to the left (-) will shift the
transmission into 3rd gear.
4.7L and 5.7L Engine
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. 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 downshift). For example, if you are
in DRIVE and are in 3rd (direct) gear, when you tap the
shift lever one time to the left (-), the display will show 4
(ERS 4 is direct gear). Another tap to the left (-) will shift
the transmission down to ERS 3 (the added underdrive
gear). When in the DRIVE position in 5th gear, the first
tap to the left (-) will downshift the transmission and
display 5 (ERS 5 is the same as normal 4th gear). Another
tap to the left (-) will shift the transmission down to ERS
4 (direct 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.
