ESC On
This mode is the normal operating mode for ESC on
two-wheel drive vehicles. Whenever the vehicle is
started, the ESC system will be in this mode. This mode
should be used for most driving situations. ESC should
only be turned off for specific reasons as noted below.
ESC Partial Off
This mode is entered by momentarily pressing the “ESC
Off” switch.
When in the “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. When in the “Partial Off”
mode, ESC will operate without engine torque manage-
ment. 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 press the
“ESC Off” switch. This will restore the normal “ESC On”
mode of operation.
WARNING!
• When in ؆Partial Off؆ mode, the TCS functionality
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 sys-
tem is reduced.
• Trailer Sway Control (TSC) is disabled when the
ESC system is in the ؆Partial Off؆ mode.
