Driving On Grades Reduce speed and shift to a lower gearbefore you start down a longor 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, use the highest gear possible. If you cannot maintain posted speeds, driving at a lower speed may help avoid overheating your engine and transaxle. If you have a manual transaxle with fifth gear, it's better not to use fifthgear. Just drive in fourth gear (or, as you need to, a lower gear). Parking on Hills You really should not park your vehicle, with a trailer attached, on a hill. If something goes wrong, your rig could start to move. People can be injured, and both your vehicle and the trailer can be damaged. But if you ever have to park your rig on a hill, here's how to do it: 1 . Apply your regularbrakes, but don't shift into manual transaxle. PARK (P) yet, or into gear for a under the trailerwheels. 2. Have someone place chocks 3. When the wheel chocks are 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 to PARK (P), or REVERSE(R) for a manual transaxle. 5. Release theregular brakes. 4-37
