nated when ESC is off. To turn ESC on again,
momentarily press the “ESC Off” button. This
will restore the normal “ESC On” mode of
operation.
NOTE:
•
“Full Off” is the only operating mode for
ESC in 4WD LOW range. The ESC system
will be in this mode whenever the vehicle
is started in 4WD LOW range or the trans-
fer case is shifted into 4WD LOW range.
•
The “ESC OFF” message will display and
a chime will sound when the shift lever is
moved from any position to the PARK
position and then moved out of the PARK
position. This will occur even if the mes-
sage was cleared previously.
WARNING!
With the ESC switched off, 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. “Full Off” mode is only intended for
off-highway or off-road use.
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 igni-
tion switch is turned to the ON
position. 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 your 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 pos-
sible. Be sure to adapt your speed and driving
to the prevailing road conditions.
NOTE:
•
The “ESC Activation/Malfunction Indica-
tor Light” and the “ESC OFF Indicator
Light” come on momentarily each time
the ignition switch is turned ON.
•
Each time the ignition is turned ON, the
ESC system will be ON even if it was
turned off previously.
•
The ESC system will make buzzing or
clicking sounds when it is active. This is
normal; the sounds will stop when ESC
becomes inactive following the maneuver
that caused the ESC activation.
The “ESC OFF Indicator Light” in-
dicates the Electronic Stability
Control (ESC) is off.
