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 back on by momentarily
pressing the “ESP OFF” switch. This may be done while
the vehicle is in motion.
Full Off (Four-Wheel Drive Models Only)
This mode is intended for off-highway or off-road use
when ESP stability features could inhibit vehicle maneu-
verability due to trail conditions. This mode is entered by
pressing and holding the “ESP OFF” switch for five
seconds when the vehicle is stopped and the engine is
running. After five seconds, the “ESP/TCS Indicator
Light” will illuminate, and the “ESP OFF” message will
appear in the Electronic Vehicle Information Center
(EVIC). Refer to “Electronic Vehicle Information Center
(EVIC)” in “Understanding Your Instrument Panel” for
further information.
In this mode, ESP 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 system returns to “Partial Off”
mode, described above. When the vehicle speed drops
below 35 mph (56 km/h), the ESP system shuts off. ESP
is deactivated at low vehicle speeds so that it will not
interfere with off-road driving, but ESP function returns
to provide the stability feature at speeds above 40 mph
(64 km/h). The “ESP/TCS Indicator Light” will always
be illuminated when ESP is off. To turn ESP on again,
momentarily press the “ESP OFF” switch. This will
restore the normal “ESP On” mode of operation.
NOTE: The “ESP OFF” message will display, and the
audible chime will sound, when the shift lever is placed
