Electronic Stability Program (ESP)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESP cor-
rects for over/under steering of the vehicle by applying
the brake of the appropriate wheel to assist in counter-
acting the over/under steer condition. Engine power
may also be reduced to help the vehicle maintain the
desired path.
ESP 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, ESP applies the brake of the appropri-
ate wheel to assist in counteracting the oversteer or
understeer condition.
• 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.
ESP ON
This is the normal operating mode for ESP on 2WD
vehicles. Whenever the vehicle is started, the ESP system
will be in this mode. This mode should be used for most
driving situations. ESP should only be turned off for
specific reasons as noted below.
ESP Partial OFF
This mode is entered by momentarily depressing the ESP
OFF switch (located in the center switch bank, next to the
hazard flasher switch).
When in Partial OFF mode, the TCS portion of
ESP, except for the “limited slip” feature de-
scribed in the TCS section, has been disabled
and the ESP/TCS Indicator Light will be illu-
minated. All other stability features of the ESP function
normally. This mode is intended to be used if the vehicle
is in deep snow, sand or gravel conditions and more
wheel spin than ESP would normally allow is required to
