Jeep 2015 Wrangler - Owner Manual - Manual (Page 479)

The ESC system has three available operating modes in
4H range. The system has one operating mode in 4L
range. Two-wheel drive vehicles and four-wheel drive
vehicles in 2H range have two operating modes.
4H Range (4WD Models)
ESC On
This is the normal operating mode for ESC in 4H range.
ESC Partial Off
This mode is entered by momentarily pressing the ESC
OFF switch. When in ЉESC Partial OffЉ mode, the TCS
portion of ESC (except for the limited slip feature de-
scribed in the TCS section), has been disabled and the
Љ
ESC Off Indicator LightЉ will be illuminated.
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 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.
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 ЉESC Partial
OffЉ mode by pressing the ESC OFF switch. Once the
situation requiring ESC to be switched to the ЉESC Partial
OffЉ mode is overcome, turn ESC back on by momen-
tarily pressing the ESC OFF switch. This may be done
while the vehicle is in motion.
