Jeep 2009 Liberty - Owner Manual - Manual (Page 336)

Depending upon model and mode of operation, the ESP
system has up to three operating modes: “ESP On”
“Partial Off,” and “Full Off.”
ESP On — Two-Wheel Drive Vehicles and Four-Wheel
Drive Vehicles in 2WD and 4WD High Range
This is the normal operating mode for ESP when operat-
ing 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 ESP system will be in “ESP 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. ESP 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 ESP activation, which allows for more wheel
spin than what ESP normally allows.
The “ESP OFF” button is located in the lower switch bank
below the climate control. To enter the “Partial Off”
mode, momentarily depress the “ESP OFF” button and
the
ЉESP/TCS Indicator Light” will illuminate. To turn
the ESP on again, momentarily depress the ЉESP OFFЉ
button and the ЉESP/TCS Indicator Light” will turn off.
This will restore the normal “ESP On” mode of operation.
