The ESC system has two available operating modes in

4WD HIGH range and two-wheel drive vehicles, and one

operating mode in 4WD LOW range.
High Range (Four-Wheel Drive Models) Or
Two-Wheel Drive Models
On

This is the normal operating mode for ESC in 4WD HIGH

range and in two-wheel drive vehicles. Whenever the

vehicle is started or the transfer case (if equipped) is

shifted from 4WD LOW range or NEUTRAL back to

4WD HIGH range, the ESC system will be in this “On”

mode. This mode should be used for most driving

situations. ESC should only be turned to “Partial Off”

mode for specific reasons as noted below.
Partial Off

This mode is entered by momentarily pressing the “ESC

OFF” switch. When in “Partial Off” mode, the TCS

portion of ESC, except for the BLD 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 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”

mode by pressing the “ESC OFF” switch. Once the

situation requiring ESC to be switched to the “Partial

Off” 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.
