ESC Operating Modes
The “ESC Off” switch is located in the center
switch bank, next to the hazard flasher switch.
ESC On
This mode is the normal operating mode for ESC
equipped 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 management. 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.
