driving maneuvers. It cannot prevent wheel lift due to
other factors, such as road conditions, leaving the road-
way, or striking objects or other vehicles.

WARNING!

Many factors, such as vehicle loading, road condi-
tions, and driving conditions, influence the chance
that wheel lift or rollover may occur. ERM cannot
prevent all wheel lift or rollovers, especially those
that involve leaving the roadway or striking objects
or other vehicles. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of an
ERM-equipped vehicle must never be exploited in a
reckless or dangerous manner, which could jeopar-
dize the user’s safety or the safety of others.

Electronic Stability Program (ESP)

This system enhances directional control and stability of
the vehicle under various driving conditions. ESP cor-
rects for over-steering and under-steering the vehicle by
applying the brake of the appropriate wheel. Engine
power may also be reduced to help the vehicle maintain
the desired path.

The ESP uses sensors in the vehicle to determine the path
that the driver intends to steer the vehicle and compares
it to the actual path of the vehicle. When the actual path
does not match the intended path, the ESP applies the
brake of the appropriate wheel to assist in counteracting
the condition of over-steer or under-steer.

• 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.
