Driving your vehicle 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 operate efficiently. On a long uphill grade, shift down and reduce your speed to around 18.6 mph (30 km/h) to reduce the possibility of engine and transaxle overheating. If your trailer weighs more than the maximum trailer weight without trailer brakes and you have an automatic transaxle, you should drive in D (Drive) when towing a trailer. Operating your vehicle in D (Drive) when towing a trailer will minimize heat build up and extend the life of your transaxle. CAUTION • When towing a trailer on steep grades (in excess of 6%) pay close attention to the engine coolant temperature gauge to ensure the engine does not overheat. If the needle of the coolant temperature gauge moves across the dial towards "H" (HOT), pull over and stop as soon as it is safe to do so, and allow the engine to idle until it cools down. You may proceed once the engine has cooled sufficiently. • You must decide driving speed depending on trailer weight and uphill grade to reduce the possibility of engine and transaxle overheating. Parking on hills Generally, you should not park your vehicle, with a trailer attached, on a hill. People can be seriously or fatally injured, and both your vehicle and the trailer can be damaged if they begin a downhill trajectory. WARNING - Parking on a hill Parking your vehicle on a hill with a trailer attached could cause serious injury or death, should the trailer break lose. However, if you ever have to park your trailer on a hill, here's how to do it: 1. Apply your brakes, but don't shift into gear. 2. Have someone place chocks under the trailer wheels. 3. When the wheel chocks are in place, release the brakes until the chocks absorb the load. 4. Reapply the brakes. Apply your parking brake, and then shift to R (Reverse) for a manual transaxle or P (Park) for an automatic transaxle. 5. Release the brakes. 5 42
