Parking on Hills
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 to do it:
1. Apply your regular brakes, but don't shift into "P7'
(Park)
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 "P" (Park).
5. Release the regular brakes.
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; and
0
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
Your vehicle will need service more often when you're
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don't overfill),
engine oil, belts, cooling system, and brake adjustment.
Each of these is covered in this manual, and the Index
will help you find them quickly. If you're trailering, it's
a good idea to review these sections before you start
your trip.
Check periodically to see that all hitch nuts and bolts are
tight.
