ESC Partial Off
This mode is entered by momentarily pushing the ESC
OFF switch. When in ESC Partial Off mode, the TCS
portion 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.
This mode is intended to be used if the vehicle is in deep
snow, sand, or gravel conditions and more wheel spin than
ESC would normally allow is required to gain traction. To
turn ESC on again, momentarily push the ESC OFF switch.
This will restore the normal “ESC On” mode of operation.
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 ESC Partial Off
mode by pushing the ESC OFF switch. Once the situation
requiring ESC to be switched to the ESC Partial Off mode
is overcome, turn ESC back on by momentarily pushing the
ESC OFF switch. This may be done while the vehicle is in
motion.
WARNING!
When in ESC Partial Off mode, the TCS function-
ality 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 ESC 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 ESC Partial Off mode.
ESC Full Off
This mode is entered by pushing and holding the ESC OFF
switch for five seconds.
In the ESC Full Off mode, the engine torque reduction
and stability features are disabled. Therefore, the enhanced
vehicle stability offered by ESC is unavailable. In an
emergency evasive maneuver, the ESC system will not
engage to assist in maintaining stability. “ESC Full Off”
mode is intended for off-highway or off-road use only.
