mode is overcome, turn ESP on by momentarily depress-

4WD Low Range
Partial Off
This is the normal operating mode for ESP in 4WD low
range. Whenever the vehicle is started in 4WD low range
or the transfer case (if equipped) is shifted from 4WD
high range or neutral to 4WD low range, the ESP system
will be in this mode. In 4WD low range, ESP function is
desensitized until the vehicle reaches a speed of 30 mph
(48 km/h). At 30 mph (48 km/h) the normal ESP stability
function returns and the ESP/TCS Indicator Light” turns
off. When the vehicle speed drops below 25 mph (40
km/h) the ESP system goes back to Partial Off. ESP is
desensitized at low vehicle speeds in 4WD low range so
that it will not interfere with off road driving but ESP
function returns to provide the stability feature at speeds
above 30 mph (48 km/h). The ABS is in a special
Off-Road mode that allows too look wheels at lower
speed if gravel is detected to gain stopping distance.
NOTE: When the vehicle is in 4WD low range, a feature
of the ESP system remains active whether the ESP is on or
off. This feature functions similar to a limited slip differ-
ential and controls the wheel spin across an axle. If one
wheel on an axle is spinning faster than the other, the
system will apply the brake of the spinning wheel and
allow more engine torque to be applied to the wheel that
is not spinning.
