G ! Vehicles with factory-mounted running-boards*: Your vehicle is equipped with a scissors-type jack (located under the cargo compartment floor) designed for use with factory-mounted running boards. Only use this jack when jacking up vehicles with factory-mounted running boards as otherwise the vehicle's underbody can be damaged. See separate instructions for scissors-type jack. The jack is designed exclusively for jacking up the vehicle at the jack take-up brackets built into both sides of the vehicle. To help avoid personal injury, use the jack only to lift the vehicle during a wheel change. Never get beneath the vehicle while it is supported by the jack. Keep hands and feet away from the area under the lifted vehicle. Always firmly set parking brake and block wheels before raising vehicle with jack. Do not disengage parking brake while the vehicle is raised. Be certain that the jack is always vertical (plumb line) when in use, especially on hills. Always try to use the jack on level surface. Make sure that the jack arm is fully seated in the jack take-up bracket. Always lower the vehicle onto sufficient capacity jackstands before working under the vehicle. 524
