ESC Operating Modes
Depending upon model and mode of operation, the ESC
system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC. When-
ever the vehicle is started, the ESC system will be in
this mode. This mode should be used for most driving
conditions. Alternate ESC modes should only be used
for specific reasons as noted in the following
paragraphs.
Partial Off
This mode may be useful if the vehicle becomes stuck.
This mode may modify Traction Control System (TCS)
and ESC thresholds for activation, which allows for
more wheel spin than normally allowed.
To enter the “Partial Off” mode, momentarily push the
ESC OFF button and the ESC OFF Indicator Light will
illuminate. To turn the ESC on again, momentarily push
the ESC OFF button and the ESC OFF Indicator Light will
turn off.
NOTE:
For vehicles with multiple partial ESC modes, the push
and release of the button may toggle the ESC modes.
Multiple attempts may be required to return to "ESC On"
mode.
WARNING!
•
When in “Partial Off” mode, the TCS functionality
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.
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 run-
ning. If the ESC Activation/Malfunction Indicator Light
comes on continuously with the engine running, a mal-
function 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 autho-
rized dealer as soon as possible to have the problem
diagnosed and corrected.
The ESC Activation/Malfunction Indicator Light starts to
flash as soon as the tires lose traction and the ESC sys-
tem 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.
The ESC OFF Indicator Light indicates that
the Electronic Stability Control (ESC) is in a
reduced mode.
NOTE:
•
The ESC Activation/Malfunction Indicator Light and
the ESC OFF Indicator Light come on momentarily
each time the ignition placed in the ON position.
•
Each time the ignition is placed in the ON position,
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.
Hill Start Assist (HSA)
HSA is designed to mitigate roll back from a complete
stop while on an incline. If the driver releases the brake
while stopped on an incline, HSA will continue to hold
the brake pressure for a short period. If the driver does
not apply the throttle before this time expires, the sys-
tem will release brake pressure and the vehicle will roll
down the hill as normal.
The following conditions must be met in order for HSA
to activate:
•
The feature must be enabled.
•
The vehicle must be stopped.
•
The parking brake must be off.
