Turn Signals When Towing a Trailer

When you tow a trailer, your vehicle has to have
extra wiring.
The arrows on your instrument panel will flash whenever
you signal a turn or lane change. Properly hooked up,
the trailer lamps will also flash, telling other drivers
you are about to turn, change lanes, or stop.
When towing a trailer, the arrows on your instrument
panel will flash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind
you are seeing your signal when they are not. It
is important to check occasionally to be sure the trailer
bulbs are still working.

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), you may prefer to drive in THIRD (3)
instead of DRIVE (D) or, as you need to, a lower
gear. This will minimize heat build-up and extend the life
of your transmission.

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.
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).
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 shift into PARK (P).
5. Release the regular brakes.
