2002 Pontiac Firebird Owner's Manual - Page 204

If you put things inside your vehicle -- like suitcases, tools, packages or anything else -- they will go as fast as the vehicle goes. If you have to stop or turn quickly, or if there is a crash, they'll keep going. Towing a Trailer CAUTION: If you don't use the correct equipment and drive properly, you can lose control when you pull a trailer. For example, if the trailer is too heavy, the brakes may not work well -- or even at all. You and your passengers could be seriously injured. You may also damage your vehicle; the resulting repairs would not be covered by your warranty. Pull a trailer only if you have followed all the steps in this section. Ask your dealer for advice and information about towing a trailer with your vehicle. CAUTION: Things you put inside your vehicle can strike and injure people in a sudden stop or turn, or in a crash. D Put things in the rear area of your vehicle. Try to spread the weight evenly. D Never stack heavier things, like suitcases, inside the vehicle so that some of them are above the tops of the seats. D Don't leave an unsecured child restraint in your vehicle. D When you carry something inside the vehicle, secure it whenever you can. D Don't leave a seat folded down unless you need to. 4-32
