also the normal mode for operating a four-wheel
drive vehicle in 2WD or 4WD HIGH range. The
ESC system will be in “ESC On” mode when-
ever the vehicle is started or the power transfer
unit (if equipped) is shifted out of 4WD LOW
range. This mode should be used for most
driving situations. ESC should only be turned to
“Partial Off” or “Full Off” for specific reasons as
noted. Refer to “Partial Off” and to “Full Off” for
additional information.
Partial Off — Two-Wheel Drive Vehicles And
Four-Wheel Drive Vehicles In 2WD And 4WD
High Range
The “Partial Off” mode is intended for driving in
deep snow, sand, or gravel. This mode raises
the threshold for TCS and ESC activation,
which allows for more wheel spin than what
ESC normally allows.
The “ESC Off” button is located in the lower
switch bank above the climate control. To enter
the “Partial Off” mode, momentarily press the
“ESC Off” button and the
" ESC Off " indicator light
will illuminate. To turn the ESC on again, momen-
tarily press the
" ESC OFF " button and the " ESC
Off " indicator light will turn off. This will restore the
normal “ESC On” mode of operation.
WARNING!
•
When in “Partial Off” mode, the TCS func-
tionality of ESC, (except for the limited slip
feature described in the TCS section), has
been disabled and the “ESC Off Indicator
Light” will be illuminated. When in “Partial
Off” mode, the engine power reduction
feature of TCS is disabled, and the en-
hanced vehicle stability offered by the ESC
system is reduced.
•
Trailer Sway Control (TSC) is disabled
when the ESC system is in the
" Partial Off "
mode.
NOTE:
To improve the vehicle’s traction when driv-
ing with snow chains, or when starting off in
deep snow, sand, or gravel, it may be desir-
able to switch to the “Partial Off” mode by
momentarily pressing the “ESC Off” button.
Once the situation requiring “Partial Off”
mode is overcome, turn ESC back on by
momentarily pressing the “ESC Off” button.
This may be done while the vehicle is in
motion.
Full Off — Four-Wheel Drive Vehicles In 4WD
High And 4WD Low Range
The “Full Off” mode is intended for off-highway
and off-road use when ESC stability features
could inhibit vehicle maneuverability due to trail
conditions.
The “ESC Off” button is located in the lower
switch bank above the climate control panel. To
enter “Full Off” mode, press and hold the “ESC
Off” button for five seconds while the vehicle is
stopped with the engine running. After five
seconds, the
" ESC Off " indicator light will illumi-
nate and an “ESC Off” message will appear in
the odometer.
