Parking on Hills But if you ever have to park your rig on a hill, here is how to do it: 1. Apply your regular brakes, but do not shift into PARK (P) for an automatic transaxle, or into gear for a manual transaxle. When parking uphill, turn your wheels away from the curb. When parking downhill, turn your wheels into the curb. 2. Have someone place chocks under the trailer wheels. 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 shift into PARK (P) for an automatic transaxle or REVERSE (R) for a manual transaxle. 5. Release the regular brakes. {CAUTION: 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. 4-43
