the intended path, ESC applies the brake of the appro-
priate wheel to assist in counteracting the oversteer or
understeer condition.
• Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
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. When-
ever 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 “Partial
Off” or “ESP Off” for specific reasons as noted below.
ESC Partial Off
This mode is entered by momentarily pressing the “ESC
Off” switch. When in
ЉPartial OffЉ mode, the TCS portion
of ESC, except for the “limited slip” feature described in
the TCS section, has been disabled and the
ЉESC Off
Indicator Light Љ 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 ESC would nor-
mally 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.
NOTE: To improve the vehicle’s traction when driving
with snow chains or starting off in deep snow, sand or
gravel, it may be desirable to switch to the “Partial Off”
