Driving On Grades Parking on Hills You really should not park your vehicle, with a trailer attached, on a hill. If somethinggoes wrong, your rig could start to move. Peoplecan be injured, and both your vehicleand the trailer can be damaged. But if you ever have to park your rig on a here's hill, how to do it: 1. Apply your regular brakes, but don't shift into PARK (P) yet. NOTICE: Do not tow on steep, continuous grades exceeding 6 miles (9.6 km). Extended, higher than normal engine and transaxle temperatures may result and damage your vehicle. Frequent stops are very important to allow the engine and transaxle to cool. Reduce speed and shift a lower gear before you start to down a long or steep downgrade. If you don't shift down, you might have use your brakesso much that to they would get hot and longer work well. no 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. Pay particular attentionto the engine coolant gage. the If indicator is in the redarea, turn off theair conditioning (if you havethis option) to reduce engine load(see "Engine Overheating" inthe Index). 2. Have someone place chocks under the trailer wheels. 3. When the wheel chocksare in place, release the regular brakes until the chocks absorb the load. 4. Reapply the regular brakes. Then apply your parking brake, and then shift PARK (P). to 5. Release the regular brakes.
