Turn Signal and Lane Change Indicator
The turn signal has two upward (for Right) and two
downward (for Left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the lever all the way up or down.
When the turn is finished, the lever will return
automatically.
A green arrow on the
instrument panel will flash
in the direction of the turn
or lane change.
To signal a lane change,
just raise or lower the lever
until the green arrow
starts
to flash. Hold it there until
you complete your lane
change. The lever will
return by itself when you
release it.
As you signal a turn or a lane change, if the arrows don’t
flash but just
stay on, a signal bulb may be burned out
and other drivers won’t
see your turn signal.
If a bulb
is burned out, replace it to help avoid an
accident. If the green arrows don’t go on at all when you
signal a turn, check the
fuse (see “Fuses 8z Circuit
Breakers” in the Index) and for burned-out bulbs.
Turn Signal Reminder
If your turn signal is left on for more than % of a mile, a
chime will sound.
To turn off the chime, move the turn
signal lever to the off position.

Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want to get t\
o
know your rig. Acquaint yourself with the
feel of
handling and braking with the added weight of the trailer.
And always keep in mind that the vehicle you
are driving
is now a good deal longer and not nearly
so responsive as
your vehicle is by itself.
Before you
start, check the trailer hitch and platform, safety
chains, electrical connector, lights, tires and mirror
adjustment. If the trailer has electric brakes,
start your vehicle
and trailer moving and then apply the trailer brake controller \
by hand to be sure the brakes
are working. This lets you
check your electrical connection at the same time. During
your trip, check occasionally
to be sure that the load is secure,
and that the lights and any trailer brakes are still working.
Following Distance
Stay at least twice as fit, behind the vehicle ahead as you
would when driving your vehicle without a trailer. This
can help you avoid situations that require heavy braking
and sudden turns.
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 nrns
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 Mler
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.
