1998 CHEVROLET ASTRO service

Downloaded from www.Manualslib.com manuals search engine NOTICE:
If your key seems stuck in LOCK and you can’t
turn it, be sure you are using the correct key;
if
so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. But turn the key only with your hand.
Using
a tool to force it could break the key or the
ignition switch.
If none of this works, then your
vehicle needs service.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won’t start in any other position -- that’s a
safety feature.
To restart when you’re already moving,
use NEUTRAL (N) only.
NOTICE:
Don’t try to shift to PARK (P) if your vehicle is
moving.
If you do, you could damage the
transmission. Shift to PARK
(P) only when your
vehicle is stopped.
1. Without pushing the accelerator pedal, turn your
ignition key
to START. When the engine starts, let
go of the key. The idle speed will go
down as your
engine gets warm.
NOTICE:
Holding your key in START for longer than
15 seconds at a time will cause your battery to be
drained much sooner. And the excessive heat can
damage your starter motor.
2. If it doesn’t start right away, hold your key in
START. If it doesn’t start in 10 seconds, push the
accelerator pedal all the way down for five more
seconds, unless
it starts sooner.

channel, proceed to Step
2. Otherwise, hold down
the two outside buttons on the universal transmitter
until
the red light begins to flash rapidly
(approximately 20 seconds). Then release the
buttons. This procedure initializes the memory and
erases any previous settings for all three channels.

Downloaded from www.Manualslib.com manuals search engine 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 this 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.
Safety Belt Reminder Light
When the key is turned to RUN or START, a tone will
come
on for about eight seconds to remind people to
fasten their
safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light
will
also come on and stay on
for about 20 seconds,
then it will flash for about
55 seconds.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG. The system checks the
air bag’s electrical system for malfunctions. The light
tells
you if there is an electrical problem. The system
check includes
the air bag sensors, the air bag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the air bag system, see “Air
Bag”
in the Index.
AIR
This light will come on
when you start your engine,
and
it will flash for a few
seconds. Then the light
should go
out. This means
the system is ready.
If the air bag readiness light stays on after you start the
engine or comes
on when you are driving, your air bag
system may
not work properly. Have your vehicle
serviced right away.
The air bag readiness light should flash for a few
seconds when
you turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready
to warn you if there is a problem. If the driver’s belt is already buckled, neither the tone
nor the light will come on.
2-58

Downloaded from www.Manualslib.com manuals search engine You can only drive for a short time with the readings in
either warning
zone. If you must drive, turn off all
unnecessary accessories.
Readings in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.
Brake System Warning Light
When the ignition is on, the brake system warning light
will come
on when you set your parking brake. The light
will stay on if your parking brake doesn’t release
fully.
If it stays on after your parking brake is fully released, it
means
you have a brake problem.
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.
If the warning light comes on, there could be a brake
problem. Have
your brake system inspected right away.
BRAKE
This light should come on
briefly when
you turn the
ignition key to
RUN. If it
doesn’t come
on then, have
it fixed so it will be ready to
warn
you if there’s
a problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer
to the floor.
It may take longer to stop. If the light is still on, have the
vehicle towed for service. (See “Towing Your Vehicle”
in the Index.)
A CAUi iON:
-
Your brake system may not be working prop( y
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light
is still on after you’ve
pulled off the road and stopped carefully, have
the vehicle towed for service.

Downloaded from www.Manualslib.com manuals search engine Anti-Lock Brake System Warning Light
ANTI -
LOCK
With the anti-lock brake
system, this light will come
on when
you start your
engine and may stay
on for
several seconds.
That’s normal.
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 section.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn’t come on then, have
it fixed so it will be
ready to warn
you if there is a problem.
Engine Coolant Temperature Gage
If the gage pointer moves to
the red area, your engine
is
too hot!
It means that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions,
you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
The “Problems on the Road” section of this manual
shows
you what to do. See “Engine Overheating” in
the Index.

Your vehicle is equipped
with a computer which
monitors operation
of the
fuel, ignition and emission SERVICE
ENGINE
SOON
control systems.
This system is called OBD
I1 (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the life
of the vehicle, helping to produce a cleaner
environment. The SERVICE ENGINE
SOON light
comes on to indicate that there is a problem and service
is required. Malfunctions often will be indicated by the
system before any problem is apparent. This may
prevent more serious damage
to your vehicle. This
system
is also designed to assist your service technician
in correctly diagnosing any malfunction.

NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work
as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is
on and the engine is not
running.
If the light doesn’t come on, have it repaired.
This light will also come
on during a malfunction in one
of two ways:
Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system
on your
vehicle. Dealer or qualified service center diagnosis
and service may be required.
Light On Steady -- An emission control system
malfunction has been detected
on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.

Downloaded from www.Manualslib.com manuals search engine If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
0 Reducing vehicle speed.
0 Avoiding hard accelerations.
Avoiding steep uphill grades.
0 If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady, see “If
the Light Is
On Steady” following.
If the light continues to flash, when it is safe to do
so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart the
engine. If the light remains
on steady, see “If the Light
Is On Steady” following. If the light is still flashing,
follow
the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did
you recently put fuel into your vehicle?
If
so, reinstall the fuel cap, making sure to fully install
the cap. The diagnostic system can determine if the fuel
cap has been left off or improperly installed. A loose or
missing
fuel cap will allow fuel to evaporate into the
atmosphere. A few driving trips with the cap properly
installed should turn the light
off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off.
Have you recently changed brands of fuel?
2-63

Downloaded from www.Manualslib.com manuals search engine If so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation
on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If
you experience one or more of these conditions,
change
the fuel brand you use. It will require at least one
full tank of the proper fuel to turn the light off.
If none of
the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.
Oil Pressure Gage
The oil pressure gage shows
the engine oil pressure in
psi (pounds per square inch)
when the engine
is running.
Canadian vehicles indicate pressure
in kPa (kilopascals).
Oil pressure may vary with engine speed, outside
temperature and
oil viscosity, but readings above the
low pressure zone indicate
the normal operating range.
A reading in the low pressure zone may be caused by a
dangerously low oil level or other problems causing
low
oil pressure.
