RAM 2015 1500, Operating Information Manual, Page: 328 / 998

NOTE:
To improve the vehicle’s traction when driv-
ing with snow chains or starting off in deep
snow, sand or gravel, it may be desirable to
switch to the “ESC Partial Off” mode by
pressing the “ESC Off” switch. Once the
situation requiring ESC to be switched to the
“ESC Partial Off” mode is overcome, turn
ESC back on by momentarily pressing the
“ESC Off” switch. This may be done while
the vehicle is in motion.
WARNING!
•
When in “ESC Partial Off” mode, the TCS
functionality of ESC, (except for the limited
slip feature described in the TCS section),
has been disabled and the “ESC Off Indi-
cator Light” will be illuminated. When in
“ESC Partial Off” mode, the engine power
reduction feature of TCS is disabled, and
the enhanced vehicle stability offered by
the ESC system is reduced.

WARNING! (Continued)
•
Trailer Sway Control (TSC) is disabled
when the ESC system is in the
" ESC
Partial Off " mode.
All Four-Wheel Drive Vehicles In 4WD
AUTO And 4WD LOCK Modes Can Also
Choose The Following ESC Operating
Mode. This Is The Only Selectable ESC
Operating Mode in 4WD LOW:
ESC Full Off
This mode is intended for off-road use when
ESC stability features could inhibit vehicle ma-
neuverability due to trail conditions. This mode
is entered by pressing and holding the “ESC
Off” switch for five seconds when the vehicle is
stopped and the engine is running. After five
seconds, the “ESC Off Indicator Light” will illu-
minate. Press and release the trip odometer
button located on the instrument cluster to clear
this message.
NOTE:
The “ESC OFF” message will display and
the audible chime will sound when the shift
lever is placed into the PARK position from
any other position and then moved out of
the PARK position. This will occur even if
the message was previously cleared.
In this mode, ESC and TCS except for the
“limited slip” feature described in the TCS sec-
tion are turned off until the vehicle reaches a
speed of 40 mph (64 km/h). At 40 mph (64 km/h)
the system returns to “ESC Partial Off” mode,
described above. When the vehicle speed
drops below 35 mph (56 km/h) the ESC system
reverts back to
" ESC Full Off " . ESC is off at low
vehicle speeds so that it will not interfere with
off-road driving but ESC function returns to
provide the stability feature at speeds above
40 mph (64 km/h). The “ESC Off Indicator Light”
will always be illuminated when ESC is in
" ESC
Partial Off " and " ESC Full Off " . To turn ESC on
again, momentarily press the “ESC Off” switch.
This will restore the normal “ESC On” mode of
operation.
