Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects 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 condi-
tion. Engine power may also be reduced to help the
vehicle maintain the desired 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 position.
•
Under-steer - when the vehicle is turning less than
appropriate for the steering wheel position.
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 system 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 Indicator Light” will be illumi-
nated. This mode is intended to be used if the vehicle is
