Dodge 2009 Ram 1500 - Manual (Page 323)

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, first
through third gear are underdrive gears, and fourth gear
is direct drive. ERS fifth gear (Overdrive) is the same as
the normal fourth gear.
When in the DRIVE position in first through fourth gear,
the first tap down (-), will display the ERS designation for
the current gear (the transmission will not downshift).
For example, if you are in DRIVE and are in third (direct)
gear, when you tap the shift lever/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). When in the DRIVE
position in fifth gear, the first tap down (-) will downshift
the transmission and display 5 (ERS 5 is the same as
normal fourth gear). Another tap down (-) will shift the
transmission down to ERS 4 (direct gear).

To exit ERS mode, press and hold the top of the switch (+)
until “D” is once again highlighted in the instrument
cluster display.
