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,
check
for burned-out bulbs and
then
check
the
fuse.

Oil
Pressure
Light
If
you
have a problem with
your oil, this light may stay
on after you start your
engine, or come
on
when
you
are driving.
This
indicates
that oil is not going through your engine
quickly
enough to keep
it
lubricated. The engine
could be low on oil or could have
some other
oil
problem.
Have it fixed right away.
The
oil
light could also come
on in the following
situations:
The
light
will
come
on briefly when
you turn on the
ignition to show
you that it is working properly.
If
it
doesn’t
come
on
with the ignition on,
you
may
have
a
problem
with
the fuse or bulb.
Have it fixed
right
away.
e
Sometimes
when
the engine
is
idling at
a stop,
the light may
blink
on
and
off.
This is normal.
Do..
.
keep
driving
if
the
oil
pressure
is
low.
If
you do, your
engine
can
become
so
hot
that
it
catches
fire. You or
others
could
be
burned.
Check
your
oil
as
soon as possible
and
have
your
vehicle
serviced.

It’s
a
good idea to check
your engine oil every time you
get fuel. In order to get an accurate reading, the
oil
must be warm and the vehicle must be
on level ground.
The engine

the yellow loop
located near the front
of the engine. See

The
tire
inflation
monitor system detects differences in
tire
rotation
speeds
that are caused by changes
in
tire pressure.
The
system can alert you about
a
low
tire
-
but
it
doesn't
replace normal tire maintenance.
See
Tires
on
page
5-57.
When
the
LOW
TIRE
light comes on, you should stop
as
soon
as
you
can
and check all your tires for
damage.
(If
a
tire is
flat,
see
If
a Tire Goes Flat
on
page
5-66.)
Also
check the tire pressure
in
all four tires
as
soon
as
you
can.
See
lnflation
--
Tire Pressure
on page
5-57.
The
LOW
TIRE
light
will
also be displayed (while the
ignition is on)
until
you
reset (calibrate) the system.
Don't
reset
the
tire inflation monitor system
without
first
correcting
the
cause of the problem and checking
and
adjusting
the
pressure in all four tires. If you reset
the
system
when
the
tire pressures are incorrect,
the
system
will
not
work properly and may
not alert you
when
a
tire is
low.
9ny time
you
adjust
a
tire's pressure, rotate your tires,
need
to
reset
(calibrate) the tire inflation monitor
system.
You'll
also
need
to
reset the system whenever you
buy
new
tires
and
whenever the vehicle's battery has
been
disconnected.

To reset (calibrate) the system:
1. Turn the ignition to RUN.
2. Locate the red RESET
button inside of your
instrument panel fuse
block.
The fuse block is located under the cover labeled
FUSES,
which is at the end of the instrument
panel on the passenger's
side of the vehicle.
The RESET button is the first button
in
the top
row of the fuse block.
3.
Press and hold the RESET
button
for about
five seconds.
The LOW TIRE light will
come on and
flash
three times. Then
it
will go
off.
If the light doesn't
go
off, see your
dealer
for
service.
-.
I
ne system compietes the calibration process auring
driving.
The system normally takes 15 to 20 minutes of driving
in each of three speed ranges
to
"learn" tire pressures.
The speed ranges are 15 to
40 mph (25 to
65
km/h),
40
to
65
mph
(65
to 105 km/h) and above
65 mph
will alert you after two to eight
minutes
if
a tire is
12 psi
(83
kPa) different from the other three tires.
Detection thresholds may be higher and detection
times may be longer on rough
roads, curves and at
high speeds. The system
is not
capable of detection
(1
05
km!h).

Electrical
System
Add-on Electrical
Equipment
Notice:
Don’t add anything electrical to your
vehicle unless you check
with
your
dealer first.
Some
electrical
equipment
can damage your vehicle
and the damage wouldn’t be covered by
your
warranty.
Some add-on electrical equipment
can
keep
other components from working as they
should.
Your
vehicle
has an air bag system. Before attempting
to add anything electrical to your vehicle, see

Headlamp
Wiring
The
headlamp wiring is protected by a circuit breaker in
the underhood fuse block. An electrical overload will
cause the lamps to go
on and
off,
or in some
cases to
remain
off.
If this happens,
have your headlamp
system
checked right away.
Windshield
Wiper
Fuses
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 instrument panel fuse
block
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 in the
fuse
block wiring itself. This greatly reduces
the
chance of fires caused by electrical problems.
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.
