Partial Off
The “Partial Off” mode is intended for times when a more
spirited driving experience is desired. This mode may
modify TCS and ESC thresholds for activation, which allows
for more wheel spin than normally allowed. This mode may
be useful if the vehicle becomes stuck.
To enter the “Partial Off” mode, momentarily push the “ESC
Off” switch and the “ESC Off Indicator Light” will illumi-
nate. To turn the ESC on again, momentarily push the “ESC
Off” switch and the “ESC Off Indicator Light” will turn off.
NOTE:
For vehicles with multiple partial ESC modes a momentary
button push will toggle the ESC mode. Multiple momentary
button pushed may be required to return to ESC On.
Full Off — If Equipped
This mode is intended for off-highway or off-road use 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” switch 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” switch.
NOTE:
System may switch from ESC “Full Off” to “Partial Off”
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 so
equipped.
WARNING!
When in “Partial Off” mode, the TCS functionality 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 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.
