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 two available operating modes.
Full On
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” for
specific reasons as noted below.
Partial Off
This mode is entered by momentarily pressing the “ESC
Off” switch. 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.
NOTE:
To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the “Partial Off”
mode by pressing the “ESC Off” switch. Once the situa-
