118 SAFETY
(Continued)
Oversteer — when the vehicle is turning more than
appropriate for the steering wheel position.
Understeer — when the vehicle is turning less than
appropriate for the steering wheel position.
The “ESC Activation/Malfunction Indicator Light” located
in the instrument cluster will start to flash as soon as the
ESC system becomes active. The “ESC Activation/
Malfunction Indicator Light” also flashes when the 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.
ESC Operating Modes
NOTE:
Depending upon model and mode of operation, the ESC
system may have multiple operating modes.
ESC On
“ESC On” is the normal operating mode for the ESC.
Whenever 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
The “Partial Off” mode is intended for times when a more
spirited driving experience is desired. This mode may
modify TCS and ESC thresholds for activation, which
allows for more wheel spin than normally allowed. This
mode may be useful if the vehicle becomes stuck.
To enter the “Partial Off” mode, momentarily push the
“ESC OFF” switch and the “ESC OFF Indicator Light” will
illuminate. To turn the ESC on again, momentarily push
the “ESC OFF” switch and the “ESC OFF Indicator Light”
will turn off.
NOTE:
For vehicles with multiple partial ESC modes, a
momentary button push will toggle the ESC mode. Multiple
momentary button pushes may be required to return to
“ESC On” mode.
Full Off — If Equipped
The “Full Off” 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”
switch 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” switch.
WARNING!
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 conditions. ESC cannot prevent accidents,
including those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. ESC also cannot prevent accidents resulting
from loss of vehicle control due to inappropriate
driver input for the conditions. Only a safe, attentive,
and skillful driver can prevent accidents. The capabil-
ities of an ESC equipped vehicle must never be
exploited in a reckless or dangerous manner which
could jeopardize the user’s safety or the safety of
others.
Vehicle modifications, or failure to properly maintain
your vehicle, may change the handling characteris-
tics of your vehicle, and may negatively affect the
performance of the ESC system. Changes to the
steering system, suspension, braking system, tire
type and size or wheel size may adversely affect ESC
performance. Improperly inflated and unevenly worn
tires may also degrade ESC performance. Any vehicle
modification or poor vehicle maintenance that
reduces the effectiveness of the ESC system can
increase the risk of loss of vehicle control, vehicle
rollover, personal injury and death.
WARNING!
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.
