Parking on Hills

{

CAUTION:

Parking the vehicle on a hill with the trailer
attached can be dangerous. If something goes
wrong, the rig could start to move. People can be
injured, and both the vehicle and the trailer can be
damaged. When possible, always park the rig on a
flat surface.

If parking the rig on a hill:

1. Press the brake pedal, but do not shift the

transmission into P (Park) yet. Turn the wheels into
the curb if facing downhill or into traffic if facing
uphill.

2. Have someone place chocks under the trailer

wheels.

3. When the wheel chocks are in place, release the

brake pedal until the chocks absorb the load.

4. Reapply the brake pedal. Then apply the parking

brake and shift into P (Park).

5. Release the brake pedal.

Leaving After Parking on a Hill

1. Apply and hold the brake pedal while you:

start the engine,

shift into a gear, and

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.

Maintenance When Trailer Towing

The vehicle needs service more often when pulling a
trailer. See this manual’s Maintenance Schedule
or Index for more information. Things that are especially
important in trailer operation are automatic transmission
fluid, engine oil, axle lubricant, belts, cooling system
and brake system. It is a good idea to inspect
these before and during the trip.

Check periodically to see that all hitch nuts and bolts
are tight.
