SAFETY 309
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 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 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 equipped).
ESC Activation/Malfunction Indicator Light
And ESC OFF Indicator Light
The ESC Activation/Malfunction
Indicator Light in the instrument
cluster will come on when the ignition
is placed in the ON/RUN mode. It
should go out with the engine running. If the
ESC Activation/Malfunction Indicator Light
comes on continuously with the engine running,
a malfunction has been detected in the ESC
system. If this light remains on after several
ignition cycles, and the vehicle has been driven
several miles (kilometers) at speeds greater
than 30 mph (48 km/h), see an authorized
dealer as soon as possible to have the problem
diagnosed and corrected.
The ESC Activation/Malfunction Indicator Light
(located in the instrument cluster) starts to
flash as soon as the tires lose traction and the
ESC system becomes active. The ESC
Activation/Malfunction Indicator Light also
flashes when TCS is active. If the ESC
Activation/Malfunction Indicator Light begins to
flash during acceleration, ease up on the
accelerator and apply as little throttle as
possible. Be sure to adapt your speed and
driving to the prevailing road conditions.
WARNING!
When in “Partial Off” mode, the TCS func-
tionality 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.
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
not 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,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot
prevent collisions.
