{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. For all wheel types, find the jacking location using the diagram above and the corresponding hoisting notches located on the bottom side of the plastic molding. The notches in the plastic molding are marked with a triangle shape to help you find them. The front location is about 7.0 inches (17.7 cm) from the rear edge of the front wheel well. The rear location is about 4.5 inches (11.4 cm) from the rear edge of the wheel well. 4. 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.
