Electronic Stability Control (ESC)

This system enhances directional control and
stability of the vehicle under various driving
conditions. ESC corrects for over-steering or
under-steering of the vehicle by applying the
brake of the appropriate wheel to assist in
counteracting the over-steering or under-
steering condition. Engine power may also be
reduced to help the vehicle maintain the de-
sired path. ESC uses sensors in the vehicle to
determine the vehicle path intended by the
driver and compares it to the actual path of the
vehicle. When the actual path does not match
the intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting the
over-steer or under-steer condition
• Over-steer - when the vehicle is turning more
than appropriate for the steering wheel po-
sition.
• Under-steer - when the vehicle is turning less
than appropriate for the steering wheel po-
sition.
ESC Operating Modes
The ESC system has three available operating
modes for four-wheel drive equipped vehicles
and two available operating modes for two-
wheel drive equipped vehicles.
Full On (Four-Wheel Drive Models) or On
(Two-Wheel Drive Models)
This is the normal operating mode for ESC.
Whenever the vehicle is started the ESC sys-
tem will be in this "On" mode. This mode should
be used for most driving situations. ESC should
only be turned to "Partial Off" or "ESC Off" for
specific reasons as noted below.
Partial Off (Four-Wheel Drive Models) or
On (Two-Wheel Drive Models)
This mode is entered by momentarily pressing
the "ESC Off" switch. When in "Partial Off"
mode, the "ESC Activation/Malfunction Indica-
tor Light" will be illuminated. This mode is
intended to be used if the vehicle is in deep
snow, sand or gravel conditions and more
wheel spin than ESC would normally allow is
required to gain traction.
To turn ESC on again, momentarily press the
"ESC Off" switch. This will restore the normal
"ESC On" mode of operation.
