RAM 2015 1500, Operating Information Manual, Page: 327 / 998

When the actual path does not match the
intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting the
oversteer or understeer condition.
•
Oversteer - when the vehicle is turning more
than appropriate for the steering wheel posi-
tion.
•
Understeer - when the vehicle is turning less
than appropriate for the steering wheel posi-
tion.
WARNING!
Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase the
traction afforded by prevailing road condi-
tions. ESC cannot prevent accidents, includ-
ing those resulting from excessive speed in
turns, driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent ac-
cidents resulting from loss of vehicle control
due to inappropriate driver input for the con-

ditions. Only a safe, attentive, and skillful
driver can prevent accidents. The capabili-
ties of an ESC equipped vehicle must never
be exploited in a reckless or dangerous
manner which could jeopardize the user’s
safety or the safety of others.
All Two-Wheel Drive Vehicles And
Four-Wheel Drive Vehicles In 2WD, 4WD
AUTO, Or 4WD LOCK Modes Can Choose
The Following ESC Operating Modes:
ESC On
This is the normal operating mode for ESC in
2WD/4WD AUTO/4WD LOCK modes and in
2WD vehicles. Whenever the vehicle is started
or the transfer case (if equipped) is shifted from
4WD LOW or Neutral, back to 4WD LOCK or
4WD AUTO, the ESC system will be in this
mode. This mode should be used for almost all
driving situations. ESC should only be turned to
" ESC Partial Off " or “ESC Full Off” for specific
reasons as noted below.
ESC Partial Off
This mode is entered by momentarily pressing
the “ESC Partial Off” switch. When in
" Partial
Off " mode, the TCS portion of ESC, except for
the “limited slip” feature described in the TCS
section, has been disabled and the
" ESC Off
Indicator Light " will be illuminated. All other
stability features of ESC function normally. This
mode is intended to be used if the vehicle is in
deep snow, sand, or gravel conditions and more
wheel spin than TCS would normally allow is
required to gain traction. To turn ESC on again,
momentarily press the “ESC Off” switch. This
will restore the normal “ESC On” mode of
operation.
