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 and reduce your speed to around 45 mph (70 km/h) to reduce the possibility of engine and transmission overheating. When towing at high altitude on steep uphill grades, consider the following: Engine coolantwill boil at a lowertemperature than at normalaltitudes. If you turn your engine off immediately after towing at high altitude on steep uphill grades, your vehicle may show signs similar to engine overheating. To avoid this, let the enginerun while parked (preferably on level ground) with the automatictransmission in PARK (P) (or the manual transmission out of gear and the parking brake applied) fora few minutes before turning the engineoff. If you do get the overheat warning, see "Engine Overheating" in the Index. Parking on Hi//s 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 todo it: 1. Apply your regular brakes,but don't shift into PARK (P) yet, or into gear for a manual transmission. 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 absorbthe load. 4. Reapply the regularbrakes. Then apply your parking brake, and then shift into PARK (P), or REVERSE (R) for amanual transmission. 5. If you have a four-wheeldrive vehicle with a manual transfer case shift lever, be sure the transfer case is in a drive gear not in NEUTRAL (N). 6. Release the parking brake. 4-48
