STARTING AND OPERATING 437 Electronic Roll Mitigation (ERM) This system anticipates the potential for wheel lift by monitoring the driver's steering wheel input and the speed of the vehicle. When ERM determines that the rate of change of the steering wheel angle and vehicle speed are sufficient to potentially cause wheel lift, it then applies the brake of the appropriate wheel and may also reduce engine power to lessen the chance that wheel lift will occur. ERM will only intervene during very severe or evasive driving maneuvers. WARNING! Many factors, such as vehicle loading, road conditions 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. The capabilities of an ERMequipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the user's safety or the safety of others. 5 ERM can only reduce the chance of wheel lift occurring during severe or evasive driving maneuvers. It cannot Electronic Stability Control (ESC) prevent wheel lift due to other factors such as road conditions, leaving the roadway or striking objects or This system enhances directional control and stability of other vehicles. the vehicle under various driving conditions. ESC corrects for oversteering or understeering of the vehicle by applying the brake of the appropriate wheel to assist in
