{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. {CAUTION: 3. Near each wheel well is a notch in the frame which the jack head fits in. The front notch is 9 inches (23 cm) back from the front wheel well. The rear notch is 8 inches (20 cm) forward from the rear wheel well. As is shown in the diagram above, if your vehicle has flared side moldings, both front and rear notches are 18 inches (46 cm) from the wheel wells. Position the jack and raise the jack head until it fits firmly into the notch in the vehicle's frame nearest the flat tire. Put the compact spare tire near you. 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. 5-66
