WARNING!
With the ESC switched off, the enhanced
vehicle stability offered by ESC and ERM are
unavailable. In an emergency evasive maneu-
ver, the ESC and ERM systems will not en-
gage to assist in maintaining stability. The
"Full Off" ESC mode is intended for off-road
use only.
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
206
driving, but the ESC function returns to provide
the stability feature at speeds above 40 mph
(64 km/h). The "ESC Activation/Malfunction In-
dicator 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.

"Full Off" mode is intended for off-road use
only.
Disabling ESC For Modified Vehicles (4WD
Models Only)
Vehicles modified with larger tires and/or sus-
pension lifts may experience early ESC activa-
tions as compared to a non-modified produc-
tion vehicle depending on lift size, tire size,
suspension changes and/or driving habits. If
early ESC activations are experienced while
driving a modified vehicle, the additional ability
to permanently turn off ESC is available. A
steering wheel/ESC button maneuver must be
performed to permanently disable ESC and
defeat the functionality of the ESC switch. Re-
peating the procedure will return the system to
normal ESC operation and restore ESC switch
functionality allowing ESC "Partial" or "Off"
modes.
