Windshield Wipers
Turn and Lane-Change Signals
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.
-
An arrow on
the instrument
panel cluster will flash in
the direction of the
turn or lane change.
To signal
a
lane change, just raise
or
lower the lever
until the 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 arrow
flashes faster than normal, 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 arrows don’t go
on
at all when you signal
a
turn,

in blown vehicle or adapter fuses.
If
you experience a
problem
see
your
dealer for additional information
on
accessory
power outlets.
Notice:
Adding
some
electrical
equipment to
your
vehicle
can damage it
or
keep
other
things
from
working as they
should.
This
wouldn’t
be
covered
by
your
warranty.
Check
with
your
dealer
before
adding
electrical
equipment,
and
never
use
anything
that
exceeds
the
amperage
rating.
When adding electrical equipment, be
sure
to follow the
proper installation instructions included with the
equipment.
Notice:
Power
outlets
are
designed
for

Accessory
Inflator
Your
vehicle
may
have
an air inflator. With it, you
can
inflate things like air mattresses and basketballs,
and
you
can also use it to bring your tires up to the
proper
pressure.
The
air inflator is located in the rear compartment
on
the
driver’s side. To
remove the cover, pull the tab
on
the cover and pull it
off.
L
This is the switch for the
air inflator.
There
may
be
an
air inflator kit stored in the glove box.
It
includes
a 20-foot
(6 m) hose
with
an
air pressure
gage
and
nozzle
adapters.
Inflating something too much
can make it
explode, and you or
others
could be injured.
Be sure to read the inflator
instructions, and
inflate any object
only
to its recommended
pressure.
To
use
your air inflator system, do the following:
1.
Turn the ignition to ACCESSORY
or
RUN.
2. Attach the appropriate nozzle adapter,
if
required,
to the end of the hose that has the pressure gage.
3.
Attach that end of the hose to the object you wish
to inflate.
4.
Remove the protective cap covering the outlet.
5. Attach the other end of the hose to the outlet.
6.
Press the accessory inflator switch. The light in
the
switch will come
on to show
the
system
is
working.
If
the air inflator system
does
not turn on or the
light does not come on, the fuse may
be
blown
or
installed incorrectly.

Fuses
and
Circuit Breakers

can damage your vehicle
and
the
damage
wouldn’t be covered by your

Headlamp
Wiring
The
headlamp wiring is protected by an internal circuit
breaker in the instrument panel fuse panel. An electrical
overload will cause the lamps to go
on

off,
or in
some
cases to remain
off.

Circuit breakers in the instrument panel 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.
Fuses
and
Circuit
Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links.
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 identical
size and rating.
If
you ever have
a
problem
on the road and don’t have
amperage or use
one of the spare fuses in the
underhood fuse block. Just pick some feature of your
vehicle that you can
get along without
-
like the radio or
cigarette lighter
-
and use its fuse,
if
it
is
the right
amperage.
Replace it
as soon as you can.
