Driving On Grades Reduce speed and shift to a lower gear before you start down a long or steep downgrade. If you do not shift down, you might have to use your brakes so much that they would get hot and no longer work well. If you are towing a trailer that weighs more than 1,000 lbs. (450 kg), drive in THIRD (3) instead of AUTOMATIC OVERDRIVE (D) (or as you need to, a lower gear). This will minimize heat build-up and extend the life of your transaxle. But if you ever have to park your rig on a hill, do the following: 1. Apply your regular brakes, but do not shift into PARK (P) yet. 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 then shift to PARK (P). 5. Release the regular brakes. Parking on Hills {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. When You Are Ready to Leave After Parking on a Hill 1. Apply your regular brakes and hold the pedal down while you: • Start your engine. • Shift into a gear. • Release the parking brake. 2. Let up on the brake pedal. 3. Drive slowly until the trailer is clear of the chocks. 4. Stop and have someone pick up and store the chocks. 4-49
