Making Turns Turn Signals WhenTowing a Trailer When you tow a trailer, your vehicle may need a different turn signal flasher and/or extra wiring. Check with your Buick dealer. The greenarrows 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 driversyou're about to turn, change lanes or stop. When towing a trailer, the green arrows on your instrument panelwill flash for turns even if the bulbs on the trailer are burned out. Thus, you may think drivers behind you are seeing your signal when they are not. It's important to check occasionally to be sure trailer the bulbs are still working. I NOTICE: Making very sharp turns while trailering could cause the trailer to come contact with the in vehicle. Your vehicle could be 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 W e u v e r s . Signal well in advance. Driving On Grades Reduce speed and shift to a lower gear before you start down a long or steep downgrade. If you don't shift down, you might have to use your brakes so much that they would get hot and no longer work well. On a long uphill grade, shift down and reduce your speed to around 45 mph (70 km/h) to reduce the possibility of engine and transaxle overheating. 4-36
