Windshield Wipers 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.

When the turn is finished, the lever will return
automatically.
0 Windshield Washer
Cruise Control (Option) instrument panel will flash
Turn Signal and Lane Change Indicator , ' in the direction of the turn
.-- A green arrow on the
I .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" in the Index)
and for burned-out bulbs.
If you have a trailer towing option with added wiring for
the .trailer lights, a different
turn signal flasher is used.
With this flasher installed, the signal indicator will flash
even if
a turn signal bulb is burned out. Check the front
and rear turn signal lights regularly to make sure they
are working.
Turn Signal Reminder
A chime will sound if your turn signal remains on after
having driven
1/2 mile, to remind you to turn off your
signal.
Operation of Lights
Although your vehicle's lighting system (headlamps,
parking lamps, fog lamps, side marker lamps and tail
lamps) meet all applicable Federal lighting
requirements, certain States and Provinces may apply their own lighting regulations that may require special
attention before you operate these lamps. For.example,
some jurisdictions may require that you operate your
lower beam lamps with fog lamps at -all times, or that
headlamps. be turned
on whenever you.must use your
windshield wipers. In addition, most jurisdictions
prohibit driving solely with parking lamps, especially at
dawn or dusk. It is recommended that you check with
you own State or Provincial highway authority. for
applicable lighting regulations.

signal lever all the way

Driving in Fog, Mist and Haze When you drive into a fog patch, your$sibility will be
reduced quickly. The biggest dangers
are striking the
vehicle ahead or being struck by the
one behind. Try to
‘‘read” the fog density down the road.
If the vehicle
ahead starts to become less clear
or, at night; if the
taillights are harder to see,
-the fog is probably
thickening. Slow down to give- traffic behind you. a
chance to slow down. Everybody then has a better chance.to avoid hitting the vehicle ahead.
A patch of derise fog may extend only for a few feet
(meters) or for miles (kilometers); you can’t really tell
while you’re
in it. You can only treat ‘the situation with
extreme tare.
One, common fog condition - sometimes called mist or
ground fog - can happen in weather that seems perfect,
especially at night or in the early
morning in valley and
low, marshy areas. You can be suddenly enveloped
in
thick, wet haze that may even coat ,your windshield. You
can often spot these fog patches .or mist layers with
your
headlights. But sometimes they can be waiting for you
as you come over a hill or dip into a. shallow valley.
Start your windshield wipers and washer, to help clear
accumulated road dirt. Slow down carefully.’
Fog can occur with high humidity or heavy frost. It can
be
so mild that- you can see through it for several
hundred feet (meters). Or-it might
he so thick .that you
can see only
a few feet (meters) ahead. It may come
suddenly
to an otherwise clear road. And it can be a
major hazard.

The fuse chart, below, shows how to tell a blown fuse
from a good fuse.

Headlights
The headlight wiring is protected by a circuit breaker in
the light switch. 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 wiring checked right
away.
Windshield Wipers.
The windsheld wiper motor is protected hy 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 and
not snow, etc., be sure to get 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 or goes
away.
Lumbar Power Seat Controls
If you have the lumbar controls for the power seat, there
is a
10 amp fuse under each seat 'wrapped in tape.
Should your
seat ever not work, this fuse should be
checked.
