CAUTION: Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack, you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack. 4. Put the jack into a notch in the frame which is located near each wheel well. The front notch is eight inches (20 cm) back from the front wheel well. The rear notch is three inches (8 cm) forward from the rear wheel well. The notches are accessible through openings in the plastic trim at the bottom of the vehicle. Position the jack and raise the jack head until it fits firmly on the ridge in the vehicle's frame nearest the flat tire. Do not raise the vehicle yet. Put the compact spare tire near you. CAUTION: Raising your vehicle with the jack improperly positioned can damage the vehicle and even make the vehicle fall. To help avoid personal injury and vehicle damage, be sure to fit the jack lift head into the proper location before raising the vehicle. 5-24
