{ CAUTION: Changing a tire can be dangerous. The vehicle can slip off the jack and roll over or fall on you or other people. You and they could be badly injured or even killed. Find a level place to change your tire. To help prevent the vehicle from moving: 1. Set the parking brake firmly. 2. Put an automatic transmission shift lever in P (Park), or shift a manual transmission to 1 (First) or R (Reverse). 3. If you have a four-wheel-drive vehicle, be sure the transfer case is in a drive gear - not in Neutral. 4. Turn off the engine and do not restart while the vehicle is raised. 5. Do not allow passengers to remain in the vehicle. To be even more certain the vehicle will not move, put blocks at the front and rear of the tire farthest away from the one being changed.

When the vehicle has a flat tire (B), use the following example as a guide to assist you in the placement of wheel blocks (A). A. Wheel Block B.
