4L Range (4WD Models)
ESC Off
This is the normal operating mode for ESC in 4L range.
Whenever the vehicle is started in 4L range, or the transfer
case (if equipped) is shifted from 4H range or NEUTRAL to
4L range, the ESC system will be in this mode. In 4L range,
ESC and TCS, except for the "limited slip" feature described
in the TCS section, are turned off until the vehicle reaches a
speed of 40 mph (64 km/h). At 40 mph (64 km/h), the
normal ESC stability function returns but TCS remains off.
When the vehicle speed drops below 35 mph (56 km/h), the
ESC system shuts off. The ESC is off at low vehicle speeds in
4L range so that it will not interfere with off-road driving,
but the ESC function returns to provide the stability feature
at speeds above 40 mph (64 km/h). The "ESC Activation/
Malfunction Indicator Light" will always be illuminated in
4L range when ESC is off.
NOTE: The "ESC OFF" message will display and the
audible chime will sound when the shift lever is placed in
the PARK position from any position other than PARK,
and then moved out of the PARK position. This will
occur even if the message was previously cleared.
WARNING!
With the ESC switched off in 4L, the enhanced
vehicle stability offered by ESC and ERM are un-
available.
2H Range (4WD Models) Or 2WD Models

This is the normal operating mode for ESC in 2H range
