Downloaded from www.Manualslib.com manuals search engine Passing
You’ll need more passing distance up ahead when you’re towing a trailer.
And, because you’re a good deal longer, you’ll need
to go much farther
beyond the passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand. Then, to move the
trailer to the left, just move that hand to the left.
To move the trailer to
the right, move your hand to
the right. Always back up slowly and, if
possible, have someone guide you.
Making Turns
When you’re turning with a trailer, make wider turns than normal. Do
this so your trailer won’t strike soft shoulders, curbs, road signs, trees, or
other objects. Avoid jerky or sudden maneuvers. Signal well
in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have a different turn signal
flasher and extra wiring. The green arrows on your instrument panel will
flash whenever
you signal a turn or lane change. Properly hooked up, the
trailer lights will also flash, telling other drivers you’re about to turn,
change lanes or stop.
When towing a trailer, the green 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’s 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 don’t shift down, you might have to use your
brakes
so much that they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your speed to around
45
mph (70 km/h) or less to reduce the possibility of engine and transaxle
overheating.
