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 ESP OFF switch. Once the situation
requiring ESP to be switched to the “Partial Off” mode is
overcome, turn ESP on by momentarily depressing the
ESP OFF switch. This may be done with the vehicle in
motion.
4WD LOW Range
Partial Off
This is the normal operating mode for ESP in 4WD LOW.
Whenever the vehicle is started in 4WD LOW or the
transfer case (if equipped) is shifted from 4WD LOCK or
NEUTRAL to 4WD LOW, the ESP system will be in this
mode. In 4WD LOW, 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 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 wheels to lock at lower speeds if gravel is detected
to shorten stopping distances.
NOTE: When the vehicle is in 4WD LOW, 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.
