Following Distance
Stay at least twice as far behind the vehicle ahead
as when driving the vehicle without a trailer.
This can help avoid situations that require heavy
braking and sudden turns.
Passing
More passing distance is needed up ahead when
towing a trailer. And, because the vehicle is a
good deal longer with the trailer, you will need to
go much farther beyond the vehicle you have
passed before you can return to the proper lane.
Backing Up
Hold the bottom of the steering wheel with one
hand. Then, to move the trailer to the left,
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
Notice: Making very sharp turns while
trailering could cause the trailer to come in
contact with the vehicle. Your vehicle could be
damaged. Avoid making very sharp turns while
trailering.
When turning with a trailer, make wider turns than
normal. Do this so the trailer will not 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 towing a trailer, the vehicle may need a
different turn signal flasher and/or extra wiring.
Check with your dealer. The arrows on the
instrument panel will flash whenever signaling 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 the instrument
panel will flash for turns even if the bulbs on the
trailer are burned out. 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.
