may think drivers behind you are seeing your signal when they are not. It's important to check occasionallyto besure the trailer bulbs are still working. Your vehicle has bulb warning lights. When you plugtrailer lights into your vehicle's lighting system,its bulb warning lights may not let you know if one of your lights goes out. So, when you have trailer lights plugged in, be sure to check your vehicle and trailer lights from time to time to be sure they're all working. Once you disconnect the trailerlights, the bulb warning lights again can tell you if one of your vehicle lights is out. 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 to "3" (Drive) and reduce your speed to 45 mph (70 km/h) to reduce the possibility of engine and transaxle overheating. Parking on Hills You really should not parkyour vehicle, with a trailer attached, on hill. a If something goes wrong, your rig could start to move. People can be injured, and both your vehicle and the trailercan be damaged. But if you ever have to parkyour rig on a hill, here's how to doit: 1. Apply your regular brakes, but don't shift into "P" (Park) yet. 2. Have someone place chocks under the trailerwheels. 3. When the wheel chocks are in place, release the regular brakes until the chocks absorb the load. 4. Reapply the regular brakes. Thenshift into "P" (Park) firmly and apply your parking brake. 5. Release the regular brakes. 222
