Following Distance Stay at least twice as far behind the vehicle ahead as you would when driving your vehicle without a trailer. This can help you avoid situations that require heavy braking and sudden turns, Passing You'll need more passing distance up ahead when you're towing a trailer. And, because you're a good deal longer, you'll need to go much farther beyond the passed vehicle before you can return to your lane. Backing Up Hold the bottom of the steering wheel with one hand. Then,to move the trailer to the left, just move that hand to the left. To move the trailer to the right, move your hand to the right. Always back up slowly and, if possible, have someone guide you. Making Turns I NOTICE: Making very sharp turns while trailering could cause the trailer to come in contact with vehicle. Your vehicle could be the damaged. Avoid making very sharp turns while trailering. When you're turning with a trailer, make wider turns than normal. Do this so your trailer won't strike soft shoulders, curbs,road signs, trees, or other objects. Avoid jerky or sudden maneuvers. Signal well in advance. Turn Signals When Towinga Trailer When you tow a trailer, your vehicle has to have extra wiring and a heavy-duty turn signal flasher (included in the optional trailering package). The green arrows on your instrument panel will flash whenever you signal a turn or lane change.Properly hooked up, the trailer lamps will also flash, telling other drivers you're about to turn, change lanes or stop. When towing a trailer, the green arrows on your instrument panel will flash for turns even if the bulbs on the trailer are burned out. Thus,you may think drivers behind you are seeing yoursignal when they are not. It's important to check occasionally to be sure the trailer bulbs are still working. 4-47
