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 do not 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. Your vehicle can tow a trailer if it is equipped with the proper trailer towing equipment. To identify what the vehicle trailering capacity is for your vehicle, you should read the information in "Weight of the Trailer" that appears later in this section. But trailering is different than just driving your vehicle by itself. Trailering means changes in handling, durability and fuel economy. Successful, safe trailering takes correct equipment, and it has to be used properly. {CAUTION: Things you put inside your vehicle can strike and injure people in a sudden stop or turn, or in a crash. • Put things in the trunk of your vehicle. In a trunk, put them as far forward as you can. Try to spread the weight evenly. • Never stack heavier things, like suitcases, inside the vehicle so that some of them are above the tops of the seats. • Do not leave an unsecured child restraint in your vehicle. • When you carry something inside the vehicle, secure it whenever you can. • Do not leave a seat folded down unless you need to. 4-38
