384 STARTING AND OPERATING WARNING! With the ESP switched off, the enhanced vehicle stability offered by ESP and ERM are unavailable. In an emergency evasive maneuver, the ESP and ERM systems will not engage to assist in maintaining stability. The "Full Off" mode is intended for offroad use only. Disabling ESP for Modified Vehicles (4WD Models Only) Vehicles modified with larger tires and/or suspension lifts may experience early ESP activations as compared to a non-modified production vehicle depending on lift size, tire size, suspension changes and/or driving habits. If early ESP activations are experienced while driving a modified vehicle, the additional ability to permanently turn off ESP is available. A steering wheel/ESP button maneuver must be performed to permanently disable ESP and defeat the functionality of the ESP switch. Repeating the procedure will return the system to normal ESP operation and restore ESP switch functionality allowing ESP "Partial" or "Off" modes. WARNING! With ESP in the permanent disable mode, enhanced vehicle stability offered by the ESP and ERM systems is unavailable. In an emergency evasive maneuver, the ESP and ERM systems will not engage to assist in maintaining stability. This disabled mode is intended for off-highway or off-road use only. Vehicle modifications requiring the owner to configure the vehicle in the ESP disabled mode, will seriously affect the vehicle's roadworthiness and safety and may lead to loss of control and/or accident resulting in possible serious or fatal injuries.
