Passing More passing distance is needed up ahead when towing a trailer. And, because the vehicle and trailer are a good deal longer, distances between any vehicles that are passed must be greater, before returning to the proper lane. Turn Signals When Towing a Trailer When towing a trailer, the vehicle may need a different turn signal flasher and/or extra wiring. Check with your dealer. The arrows on the instrument panel will flash whenever signaling a turn or lane change. Properly hooked up, the trailer lamps will also flash, telling other drivers the vehicle and trailer are about to turn, change lanes, or stop. When towing a trailer, the arrows on the instrument panel will flash for turns even if the bulbs on the trailer are burned out. You may think drivers behind you are seeing the turn signal when they are not. It is important to check occasionally to be sure the trailer bulbs are still working. The vehicle has bulb warning lights. When a trailer lighting system is plugged into the vehicle's lighting system, its bulb warning lights may not indicate if one of the lamps goes out. So, when a trailer lighting system is plugged in, be sure to check the vehicle and trailer lamps from time to time to be sure they are all working. Once the trailer lamps have been disconnected, the bulb warning lights can once again indicate if one of the vehicle lamps is out. Backing Up Hold the bottom of the steering wheel with one hand. Then, to move the trailer to the left, move that hand to the left. To move the trailer to the right, move that hand to the right. Always back up slowly and, if possible, have someone guide you. Making Turns Notice: Making very sharp turns while trailering could cause the trailer to come in contact with the vehicle. Your vehicle could be damaged. Avoid making very sharp turns while trailering. When turning with a trailer, make wider turns than normal. Do this so the trailer will not strike soft shoulders, curbs, road signs, trees, or other objects. Avoid jerky or sudden maneuvers. Signal well in advance. 329
