1994 CHEVROLET ASTRO PASSENGER brake light

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.

. The vehicle you just passed may seem to be farther away from you than
it
really is.)
Try not to pass more than one vehicle at a time on two-lane roads.
Reconsider before passing the
next vehicle.
Don’t overtake a slowly moving vehicle too rapidly. Even though the
brake lights are not flashing, it may be slowing down or starting to turn.
If you’re being passed, make it easy for the following driver to get
ahead of you. Perhaps you can ease a little to the right.
Loss of Control
Let’s review what driving experts say about what happens when the three
control systems (brakes, steering and acceleration) don’t have enough
friction where the tires meet the road to do what the driver has asked.
In any emergency, don’t give up. Keep
trying to steer and const tly seek an
escape route or area of less danger.
Skidding
In a skid, a driver can lose control of the vehicle. Defensive drivers avoid
most skids by taking reasonable care suited to existing conditions, and by
not “overdriving” those conditions. But skids are always possible.
The three types of skids correspond to your Vehicle’s three control systems.
In the braking skid your wheels aren’t rolling. In the steering or cornering
skid, too much speed or steering in a curve causes tires to slip and lose
cornering force. And in the acceleration skid too much throttle causes the
driving wheels to spin.
A cornering skid and an acceleration skid are best handled by easing your
foot off the accelerator pedal.
If your vehicle starts to slide, ease your foot off the accelerator pedal and
quickly steer the
way you want the vehicle to go. If you start steering
quickly enough, your vehicle may straighten out. Always be ready for a
second skid if it occurs.
Of course, traction
is reduced when water, snow, ice, gravel, or other
material is on the road. For safety, you’ll
want to slow down and adjust your
driving to these conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and vehicle control more
limited.

trailer brake system must not be used with your vehicle.
If everything checks out this far, then make the brake fluid tap at the
port
on the master cylinder that sends fluid to the rear brakes. But don’t
use copper tubing for this.
If you do, it will bend and finally break off.
Use steel brake tubing.
Driving with a Trailer
Towing a trailer requires a certain amount of experience. Before setting out
for the open road, you’ll want to get to know your rig. Acquaint yourself
with the feel
of handling and braking with the added weight of the trailer.
And always keep in mind that the vehicle you are driving is now a good
deal longer and not nearly
so responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform, safety chains,
electrical connector, lights, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving and then apply t\
he
trailer brake controller by hand to be sure the brakes are working. This lets
you check your electrical connection at the same time.
During your trip, check occasionally to be sure that the load is secure, and
that the lights and any trailer brakes are still working.

Downloaded from www.Manualslib.com manuals search engine Following Distance
Stay at least twice as far behind the vehicle ahead as you would when
driving your vehicle without a trailer. This can help you avoid situations that
require heavy braking and sudden turns.
Passing
You’ll need more passing distance up ahead when you’re towing a trailer.
And, because you’re a good deal longer, you’ll need to go much farther
beyond the passed vehicle before you can return to your lane. \
Backing Up
Hold the bottom of the steering wheel with one hand. Then, to move the
trailer to the left, just move that hand to the left.
To move the trailer to the
right, move your hand to the right. Always back up slowly and, if possible,
have someone guide you.
Making Turns
When you’re turning with a trailer, make wider turns than normal. Do this
so your trailer won’t strike soft shoulders, curbs, road signs, trees, or other
objects. Avoid jerky or sudden maneuvers. Signal well
in advance.
Turn Signals When Towing a Trailer
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, shift down and reduce your speed to around
45 mph
(70 km/h) to reduce the possibility of engine and transmission overheating.

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.
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.
4. Reapply the regular brakes. Then apply your parking brake, and shift to
5. Release the regular brakes.
“P” (Park).
When You Are Ready to Leave After Parking on a Hill
1. Apply your regular brakes and hold the pedal down while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re pulling a trailer. See
the Maintenance Schedule for more on this. Thin.gs that are especially
important in trailer operation are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belt, cooling system, and brake
adjustment. Each of these
is covered in this manual, and the Index will help
you find them quickly. If you’re trailering, it’s a good idea to review these
sections before you start your trip.
Check periodically
to see that all hitch nuts and bolts are tight.
Trailer Light Wiring

sure the vehicles aren’t touching each other. If they are, it could cause a
ground connection you don’t want. You wouldn’t be able to start your
vehicle, and the bad grounding could damage the electrical systems.
You could be injured if the vehicles roll. Set the parking brake firmly

Downloaded from www.Manualslib.com manuals search engine Brake Wear
Your vehicle has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make a high-pitched
warning sound when the brake pads are worn and new pads are needed. The
sound may come and go or be heard all the time your vehicle is moving
(except when you are pushing on the brake pedal firmly).
NOTICE:
Continuing to drive with worn-out brake pads could result in
costly brake repair.
Some driving conditions or climates may cause a brake squeal when the
brakes are first applied or lightly applied. This does not mean something is
wrong with your brakes.
Your rear drum brakes don't have wear indicators, but
if you ever hear a
rear brake rubbing noise, have the rear brake linings inspected. Also,
the
rear brake drums should be removed and inspected each time the tires are
removed for rotation or changing. When you have the front brakes replaced,
have the rear brakes inspected, too.
Brake linings should always be replaced as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not return to normal height, or if
there is a rapid increase in pedal travel. This could be a sign of brake
trouble.
Brake Adjustment
Every time you make a brake stop, your disc brakes adjust for wear.
If your brake pedal goes down farther than normal, your rear drum brakes
may need adjustment. Adjust them by backing
up and firmly applying the
brakes a few times.
