RAM 2015 1500, Operating Information Manual, Page: 269 / 998

Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control
allows the driver to limit the highest available
gear when the transmission is in DRIVE. For
example, if you shift the transmission into 4
(fourth gear), the transmission will not shift
above fourth gear, but will shift through the
lower gears normally.
You can switch between DRIVE and ERS mode
at any vehicle speed. When the shift lever is in
the DRIVE position, the transmission will oper-
ate automatically, shifting between all available
gears. Tapping the ERS (-) switch will activate
ERS mode, display the current gear in the
instrument cluster, and maintain that gear as
the top available gear. Once in ERS mode,
tapping (-) or (+) will change the top available
gear.
To exit ERS mode, simply press and hold the
ERS (+) switch until “D” is once again displayed
in the instrument cluster.
WARNING!
Do not downshift for additional engine brak-
ing on a slippery surface. The drive wheels
could lose their grip and the vehicle could
skid, causing a collision or personal injury.
NOTE:
To select the proper gear position for maxi-
mum deceleration (engine braking), simply
press and hold the ERS (-) switch. The
transmission will shift to the range from
which the vehicle can best be slowed down.
CAUTION!
When using ERS for engine braking while
descending steep grades, be careful not to
overspeed the engine. Apply the brakes as
needed to prevent engine overspeed.
Overdrive Operation
The automatic transmission includes an elec-
tronically controlled Overdrive (fifth and sixth
gears). The transmission will automatically shift
into Overdrive if the following conditions are
present:
•
The shift lever is in the DRIVE position.
•
The transmission fluid has reached an ad-
equate temperature.
