Spare Tire Your vehicle, when new, had a fully inflated spare tire. A spare tire may lose air over time, so check its inflation pressure regularly. See Inflation - Tire Pressure on page 5-61 and "Loading Your Vehicle" for information regarding proper tire inflation and loading your vehicle. For instruction on how to remove, install or store a spare tire, see Changing a Flat Tire on page 5-70. After installing the spare tire on your vehicle, you should stop as soon as possible and make sure the spare is correctly inflated. Have the damaged or flat road tire repaired or replaced as soon as you can and installed back onto your vehicle. This way, a spare tire will be available in case you need it again.

Some are toxic. Others can burst into flames if you strike a match or get them on a hot part of the vehicle. Some are dangerous if you breathe their fumes in a closed space. When you use anything from a container to clean your vehicle, be sure to follow the manufacturer's warnings and instructions. And always open your doors or windows when you are cleaning the inside. They can all be hazardous - some more than others - and they can all damage your vehicle, too. Do not use any of these unless this manual says you can.
