This section describes the warning lights and gages that may be on your
vehicle. The pictures will help you locate them.
Warning lights and gages can signal that something is wrong before it
becomes serious enough to cause an expensive repair or replacement.
Paying attention
to your warning lights and gages could also save you or
others from injury.
Warning lights go on when there may be or is a problem with
one of your
vehicle’s functions.
As you will see in the details on the next few pages,
some warning lights come on briefly when
you turn the ignition key just to
let you know they’re working. If you are familiar with this section, you
should not be alarmed when this happens.
Gages can indicate when there may be or
is a problem with one of your
vehicle’s functions. Often gages and warning lights work together to let you
know when there’s a problem with your vehicle.
When one of the warning lights comes
on and stays on when you are
driving, or when one
of the gages shows there may be a problem, check the
section that tells you what
to do about it. Please follow the manual’s advice.
Waiting to do repairs can be costly
- and even dangerous. So please get to
know your warning lights and gages. They’re a big help.
Brake System Warning Light
Standard Cluster Digital Cluster
Your
vehicle’s hydraulic brake system is divided into two parts. If one part
isn’t working,
the other part can still work and stop you. For good braking,
though,
you need both parts working well.

Downloaded from www.Manualslib.com manuals search engine If the light stays on, or comes on when you’re driving, your vehicle needs
service. If the regular brake system warning light isn’t
on, you still have
brakes, but you don’t have anti-lock brakes. If the regular brake system
warning light is also on,
you don’t have anti-lock brakes and there’s a
problem with your regular brakes. See “Brake System Warning Light”
earlier in this part.
Air Bag System Light
There is an air bag
readiness light
on the
instrument panel,
which shows
AIR
BAG. The system
checks for electrical
malfunctions, and the
light tells
you if there
is a problem.
You will
see this light flash for a few seconds when you turn your ignition
to
RUN or START. Then the light should go out, which means the system is
ready.
Remember, if the air bag readiness light doesn’t come
on when you start
your vehicle, or stays
on, or comes on when you are driving, your air bag
system may not work properly. Have your vehicle serviced right \
away.
Indicator Lights
Indicator lights go on when you use your turn signals, change from low
beam headlights to high beams, or when
you use your hazard flashers. The
next few pages will also tell you about the indicator lights on your vehicle
and help
you locate them.

A computer monitors operation of your fuel, ignition and emission \
control
systems. This light should come on when the ignition is on, but the engine is
not running, as a check to show you it is working. If it does not come
on at
all, have it fixed right away. If it stays on, or it comes on while you
are
driving, the computer is indicating that you have a problem. You should
take your vehicle in for service soon.
NOTICE:
If you keep driving your vehicle with this light on, after a whi\
le
the emission controls won’t work
as well, your fuel economy
won’t be as good and your engine may not run
as smoothly. This
could lead to costly repairs not covered by your warranty.

on, but the engine is not running, as a check to show you the light is
working. Then
it should go out once the engine is running. If it stays on, or
comes on while you are driving, you may have a problem with the electrical
charging system. It could indicate that you have a loose accessory drive belt,
or another electrical problem. Have it checked right away. Driving while
this light
is on could drain your battery.
The charging system light is on the left bottom corner of your standard
cluster. It is part
of the digital cluster voltmeter.
If you must drive a short distance with the light on, be certain to turn off all
your accessories, such as the radio and heatedair conditioner.

luggage carrier, you
can load things on
top
of your vehicle. The
luggage carrier has
slats attached to the
roof, side rails, and
tiedowns.
I NOTICE:
Loading cargo that weighs more than 200 pounds (91 kg) on the

Handle discs carefully. Store them in their original cases or other protective
cases and away from direct sunlight and dust. If the surface of a disc is
soiled, dampen a clean, soft cloth in a mild, neutral detergent solution and
clean it, wiping from the center to the edge.
Be sure never to touch the signal surface when handling discs. Pick up discs
by grasping the outer edges or the edge of the hole and the outer edge.
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes without being
damaged. If the mast should ever become slightly bent, you can straighten it
out by hand. If the mast is badly bent, as it might be by vandals, you should
replace it.
Check every once in
a while to be sure the mast is still tightened to the
fender.

Downloaded from www.Manualslib.com manuals search engine Passing
The driver of a vehicle about to pass another on a two-lane highway waits
for just the right moment, accelerates, moves around the vehicle ahead, then
goes back into the right lane again. A simple maneuver?
Not necessarily! Passing another vehicle on a two-lane highway is a
potentially dangerous move, since the passing vehicle occupies the same
lane as oncoming traffic for several seconds. A miscalculation, an error
in
judgment, or a brief surrender to frustration or anger can suddenly put the
passing driver face to face with the worst of all traffic accidents
- the
head-on collision.
So here are some tips for passing:
“Drive ahead.” Look down the road, to the sides, and to crossroads for
situations that might affect your passing patterns. If you have any doubt
whatsoever about making a successful pass, wait for
a better time.
0 Watch for traffic signs, pavement markings, and lines. If you can see a
sign up ahead that might indicate a
turn or an intersection, delay your
pass. A broken center line usually indicates it’s all right to pass \
(providing the road ahead is clear). Never cross a solid line on your side
of the lane or
a double solid line, even if the road seems empty of
approaching traffic.
0 Do not get too close to the vehicle you want to pass while you’re
awaiting an opportunity. For one thing, following too closely reduces
your area of vision, especially
if you’re following a larger vehicle.
Also, you won’t have adequate space if the vehicle ahead suddenly
slows
or stops. Keep back a reasonable distance.
0 When it looks like a chance to pass is coming up, start to accelerate but
stay in the right lane and don’t get too close. Time your move
so you
will be increasing speed as the time comes to move into the other lane.
If the way is clear to pass, you will have
a “running start” that more
than makes up for the distance you would lose by dropping back. And
if something happens to cause you to cancel your pass, you need only
slow down and drop back again and wait for another opportunity.
0 If other cars are lined up to pass a slow vehicle, wait your turn. But
take care that someone isn’t trying to pass you as you pull out to pass
the slow vehicle. Remember to glance over your shoulder and check
the blind spot.
0 Check your mirrors, glance over your shoulder, and start your \
left lane
change signal before moving out of the right lane to pass. Wh\
en you are
far enough ahead of the passed vehicle to see its front
in your inside
mirror, activate your right lane change signal and move back i\

No one can see as well at night as in the daytime. But as we get older these
differences increase.
A 50-year-old driver may require at least twice as
much light to see the same thing at night as a 20-year-old.
What you do in
the daytime can also affect your night vision. For example,
if you spend the day in bright sunshine you are wise to wear sunglasses.
Your eyes will have less trouble adjusting to night. But if you’re driving,
don’t wear sunglasses at night. They may cut down on glare from
headlights, but they also make a lot of things invisible.
You can be temporarily blinded by approaching lights. It can take a second
or two, or even several seconds, for your eyes to readjust to the dark. When
you are faced with severe glare (as from a driver who doesn’t lowe\
r the high
beams, or a vehicle with misaimed headlights), slow down a little. Avoid
staring directly into the approaching lights.
Keep your windshield and all the glass on your vehicle clean
- inside and
out. Glare at night is made much worse by dirt on the glass. Even the inside
of the glass can build up a film caused by dust. Dirty glass makes lights
dazzle and flash more than clean glass would, making the pupils of y\
our
eyes contract repeatedly.
Remember that your headlights light up far less
of a roadway when you are
in a turn or curve. Keep your eyes moving; that way, it’s easier to pick out
dimly lighted objects. Just as your headlights should be checke\
d regularly
for proper aim,
so should your eyes be examined regularly. Some drivers
suffer from night blindness
- the inability to see in dim light - and aren’t
even aware of
it.
Driving in the Rain
Rain and wet roads can mean driving trouble. On a wet road you can’t stop,
accelerate or turn as well because your tire-to-road traction isn’t as goo\
d as
on dry roads. And, if your tires don’t have much tread left, you’ll get even
