2004 Chevrolet Astro Owner ManualM

Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell what to do to help avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
There are also warning labels on the vehicle.
They use the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along
with the text describing the operation or information
relating to a specic component, control, message,
gage, or indicator.
If you need help guring out a specic name of
a component, gage, or indicator, reference the
following topics:

Safety Belts
Safety Belts: They Are for Everyone
This part of the manual tells you how to use safety
belts properly. It also tells you some things you should
not do with safety belts.
{CAUTION:
Do not let anyone ride where he or she can
not wear a safety belt properly. If you are in a
crash and you are not wearing a safety belt,
your injuries can be much worse. You can hit
things inside the vehicle or be ejected from it.
You can be seriously injured or killed. In the
same crash, you might not be, if you are
buckled up. Always fasten your safety belt,
and check that your passengers’ belts are
fastened properly too.
{CAUTION:
It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision,
people riding in these areas are more likely to
be seriously injured or killed. Do not allow
people to ride in any area of your vehicle that
is not equipped with seats and safety belts.
Be sure everyone in your vehicle is in a seat
and using a safety belt properly.
Your vehicle has a light
that comes on as a
reminder to buckle up.
SeeSafety Belt Reminder
Light on page 3-24.
In most states and in all Canadian provinces, the law
says to wear safety belts. Here’s why:They work.
1-13

Rear Seat Passengers
It is very important for rear seat passengers to buckle
up! Accident statistics show that unbelted people in
the rear seat are hurt more often in crashes than those
who are wearing safety belts.
Rear passengers who are not safety belted can be
thrown out of the vehicle in a crash. And they can strike
others in the vehicle who are wearing safety belts.
Rear Seat Outside Passenger PositionsLap-Shoulder Belt
These positions have lap-shoulder belts. Here is how to
wear one properly.
1. Pick up the latch plate and pull the belt across you.
Do not let it get twisted.
The shoulder belt may lock if you pull the belt
across you very quickly. If this happens, let the belt
go back slightly to unlock it. Then pull the belt
across you more slowly.
1-29

{CAUTION:
Anyone who is up against, or very close to,
any air bag when it inates can be seriously
injured or killed. Air bags plus lap-shoulder
belts offer the best protection for adults, but
not for young children and infants. Neither the
vehicle’s safety belt system nor its air bag
system is designed for them. Young children
and infants need the protection that a child
restraint system can provide. Always secure
children properly in your vehicle. To read how,
seeOlder Children on page 1-35andInfants
and Young Children on page 1-38.There is an air bag readiness light on the instrument
panel, which shows AIR BAG or the air bag symbol.
The system checks the air bag electrical system
for malfunctions. The light tells you if there is an
electrical problem. SeeAir Bag Readiness Light on
page 3-25for more information. United States
Canada

Adding Equipment to Your
Air Bag-Equipped Vehicle
Q:Is there anything I might add to the front of
the vehicle that could keep the air bags from
working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, front end sheet metal or
height, they may keep the air bag system from
working properly. Also, the air bag system may
not work properly if you relocate any of the air bag
sensors. If you have any questions about this,
you should contact Customer Assistance before
you modify your vehicle. The phone numbers
and addresses for Customer Assistance are in
Step Two of theCustomer Satisfaction Procedure
on page 7-2.
Restraint System Check
Checking Your Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors and
anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired.
Torn or frayed safety belts may not protect you in a
crash. They can rip apart under impact forces. If a belt
is torn or frayed, get a new one right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)

Power Windows
If you have power windows, the controls are located on
each of the front doors. The driver’s door also has a
switch for the front passenger window. Your power
windows will not work unless the ignition is in RUN or
ACCESSORY, or unless retained accessory power
is active. See “Retained Accessory Power” under
Ignition Positions on page 2-18.
Express-Down Window
The driver’s window switch also has an express-down
feature that allows you to lower the window without
holding the switch. Press the down arrow on the driver’s
window switch marked AUTO briey to activate the
express-down feature. The express-down feature can
be interrupted at any time by pressing the up arrow end
of the switch. Lightly tap the switch to open the
window slightly.
Sun Visors
To block out glare, you can swing down the visors.
You can also swing them from side to side. Your visors
may have an extension that can be pulled out for
additional glare protection.
Visor Vanity Mirror
Some visors have mirrors built in, with or without lamps.
Just lift the mirror cover on each visor to turn the
lamps on.
