Specifications

The ESC/TCS button
is located on the
instrument panel.
The traction control system can be turned off
or back on by pressing the ESC/TCS button.
To disable both traction control and ESC, press
and hold the button briefly.
When the ESC system is turned off, the
TRACTION OFF and ESC OFF messages will
appear, and the ESC/TCS light will be on solid
to warn the driver that both traction control
and ESC are disabled.
It is recommended to leave the system on for
normal driving conditions, but it may be necessary
to turn the system off if your vehicle is stuck in
sand, mud, ice or snow, and you want to
“rock” your vehicle to attempt to free it. It may also
be necessary to turn off the system when driving
in extreme off-road conditions where high
wheel spin is required. See If Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow on page 224.
Also, see “Competitive Driving Mode” later in
this section.
ESC may also turn off automatically if it determines
that a problem exists with the system. The ESC
OFF and SERVICE ESC messages and the
ESC/TCS light will be on solid to warn the driver
that ESC is disabled and requires service. If
the problem does not clear after restarting the
vehicle, you should see your dealer for service.
