ESC Operating Modes
Depending upon model and mode of operation, the ESC
system has up to three operating modes: "ESC On"
"Partial Off," and "Full Off."
ESC On – Two-Wheel Drive Vehicles and Four-Wheel
Drive Vehicles in 2WD and 4WD High Range
This is the normal operating mode for ESC when oper-
ating a two-wheel drive vehicle. It is also the normal
mode for operating a four-wheel drive vehicle in 2WD or
4WD HIGH range. The ESC system will be in "ESC On"
mode whenever the vehicle is started or the transfer case
(if equipped) is shifted out of 4WD LOW range. This
mode should be used for most driving situations. ESC
should only be turned to "Partial Off" or "Full Off" for
specific reasons as noted. Refer to "Partial Off" and to
"Full Off" for additional information.
Partial Off – Two-Wheel Drive Vehicles and
Four-Wheel Drive Vehicles in 2WD and 4WD High
Range
The "Partial Off" mode is intended for driving in deep
snow, sand, or gravel. This mode raises the threshold for
TCS and ESC activation, which allows for more wheel
spin than what ESC normally allows.
The "ESC Off" button is located in the lower switch bank
below the climate control. To enter the "Partial Off"
mode, momentarily press the "ESC Off" button and the
ESC Activation/Malfunction Indicator Light" will illu-
minate. To turn the ESC on again, momentarily press the
ESC Off button and the ESC Activation/Malfunction
Indicator Light" will turn off. This will restore the normal
"ESC On" mode of operation.
NOTE: To improve the vehicle's traction when driving
with snow chains, or when starting off in deep snow,
sand, or gravel, it may be desirable to switch to the
