SAFETY 275
ESC Operating Modes
Depending upon model and mode of operation, the
ESC system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC.
Wh
enever the vehicle is started, the ESC system
will be in this mode. This mode should be used for
most driving conditions. Alternate ESC modes
should only be used for specific reasons as noted
in the following paragraphs.
Partial Off
This mode may be useful if the vehicle becomes
st
uck. This mode may modify TCS and ESC
thresholds for activation, which allows for more
wheel spin than normally allowed.
To enter the “Partial Off” mode, momentarily push
the ESC OFF button and the ESC OFF Indicator
Light will illuminate. To turn the ESC on again,
momentarily push the ESC OFF button and the ESC
OFF Indicator Light will turn off.
NOTE:
For vehicles with multiple partial ESC modes, the
pu
sh and release of the button will toggle the ESC
modes. Multiple attempts may be required to
return to "ESC On" mode.
Full Off — If Equipped
This mode is intended for off-highway or off-road
u
s
e only and should not be used on any public
roadways. In this mode, TCS and ESC features are
turned off. To enter the “Full Off” mode, push and
hold the ESC OFF button for five seconds while the
vehicle is stopped with the engine running. After
five seconds, a chime will sound, the ESC OFF
Indicator Light will illuminate, and the “ESC OFF”
message will display in the instrument cluster. To
turn ESC on again, momentarily push the ESC OFF
button.
NOTE:
System may switch from ESC “Full Off” to “Partial
Of
f” mode when vehicle exceeds a predetermined
speed. When the vehicle speed slows below the
predetermined speed the system will return to ESC
“Full Off”.
ESC modes may also be affected by drive modes (if
eq
uipped).
WARNING!
When in “Partial Off” mode, the TCS function-
ality of ESC, except for the limited slip feature
de
scribed 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 enhanced 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.
WARNING!
In the ESC “Full Off” mode, the engine torque
reduction and stability features are disabled.
Therefore, enhanced vehicle stability offered
by the ESC system is unavailable. In an emer
-
gency evasive maneuver, the ESC system will
n
ot engage to assist in maintaining stability.
ESC “Full Off” mode is intended for
off-highway or off-road use only.
The Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase the
traction afforded by prevailing road condi
-
tions. ESC cannot prevent all accidents,
i
ncluding those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot
prevent collisions.
