Driving On Grades

Reduce speed and shift to a lower gear before starting

down a long hill or steep downgrade. If the vehicle

is not shifted down, the brakes might have to be

used so much that they would get hot and no longer

work well.

On a long uphill grade, shift down and reduce the

vehicle’s speed to around 45 mph (70 km/h) to reduce

the possibility of engine and transaxle overheating.

If towing a trailer, you may want to drive in THIRD (3)

instead of AUTOMATIC OVERDRIVE (D). Shift to

a lower gear as needed.

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.

But if the rig ever has to be parked on a hill, here is

how to do it:

1. Apply the regular brakes, but do not shift into

PARK (P) yet.

2. Have someone place chocks under the

trailer’s 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 the parking

brake, and shift to PARK (P).

5. Release the regular brakes.
