Turn Signals When Towing a ’Railer
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, use the highest
gear possible. If you cannot maintain
posted speeds, driving at a lower speed
may help avoid overheating your engine
and transaxle.
If you have a manual transaxle with
fifth
gear, it’s better not to use fifth gear. Just
drive in fourth gear (or, as you need to,
a lower gear).
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
P (Park) yet, or into gear
for a manual transaxle.
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.

Add-on Electrical Equbment Fuses & Circuit Breakers
The wiring circuits in your vehicle are
protected from short circuits by a
combination of fuses and circuit
breakers.
The main fuse panel is located on the
left side
of the instrument panel. To
access the fuses, open the fuse panel
door,
Look at the silver-colored band inside
the fuse.
If the band is broken or
melted, replace the fuse. Be sure you
replace
a bad fuse with a new one of the
correct
size.

Headlight Wiring
The headlight wiring is protected by a
circuit breaker in the fuse block. An
electrical overload will cause the lights
to go on and off or, in some cases, to
remain
off. If this happens, have your
headlight system checked right away.
Windshield Wipers
The windshield wiper motor is protected
by a circuit breaker and a fuse.
If the
motor overheats due to heavy snow, etc.,
the wiper will stop until the motor cools.
If the overload is caused by some
electrical problem, have it fixed.
Power Windows and Other
Power Options
Circuit breakers in the fuse panel protect
the power windows and other power accessories. When the current load is
too heavy, the circuit breaker opens and
closes, protecting the circuit until the
problem is
fixed.
