2004 CHEVROLET ASTRO load capacity

Luggage Carrier
If you have a luggage carrier, you can load things on
top of your vehicle.
The luggage carrier has side rails and crossrails
attached to the roof to secure cargo.
Be sure the cargo is properly loaded. Follow these
guidelines:
·Carrying small, heavy loads on the roof is not
recommended.
·Tie the load to the side rails. Use the crossrails only
to keep the load from sliding.
·If you need to carry long items, tie the load to the
side rails. Also tie the load to the bumpers. Do
not tie the load so tightly that the crossrails or side
rails are damaged.
·After moving the crossrails, be sure to tighten all
the slider screws.
·For the purpose of wind noise reduction, locate the
front and rear crossrails in line with the two center
supports.
Notice:Loading cargo on the luggage carrier that
weighs more than 200 lbs. (918 kg) or hangs
over the rear or sides of the vehicle may damage
your vehicle. Load cargo so that it rests on the slats
as far forward as possible and against the side
rails, making sure to fasten it securely.
Don't exceed the maximum vehicle capacity when
loading your vehicle. For more information on vehicle
capacity and loading, see
Loading Your Vehicle on
page 4-30.
To prevent damage or loss of cargo as you're driving,
check now and then to make sure the luggage
carrier and cargo are still securely fastened.
Convenience Net
You may have a convenience net in the rear of your
vehicle to help keep small items in place during sharp
turns or quick stops and starts.
The net is not designed for larger, heavier items.
You can unhook the net so that it will lie ¯at when you're
not using it.

Loading Your Vehicle
It is very important to know how much weight your
vehicle can carry. This weight is called the vehicle
capacity weight and includes the weight of all occupants,
cargo and all nonfactory-installed options. Two labels
on your vehicle show how much weight it may properly
carry, the Tire and Loading Information label and the
Certi®cation/Tire label.
{CAUTION:
Do not load your vehicle any heavier than the
GVWR, or either the maximum front or rear
GAWR. If you do, parts on your vehicle can
break, and it can change the way your vehicle
handles. These could cause you to lose
control and crash. Also, overloading can
shorten the life of your vehicle.
Tire and Loading Information Label
A. Vehicle Capacity Weight
The Tire and Loading Information label is attached to
the center pillar, near the driver's door latch. Vehicles
without a center pillar will have the Tire and Loading
Information label attached to the driver's door edge. This
label lists the number of people that can be in your
vehicle and the total weight it can carry. This weight is
called the vehicle capacity weight.
4-30

The Tire and Loading Information label also tells you
the size and recommended in¯ation pressure for
the original equipment tires on your vehicle. For more
information on tires and in¯ation see
Tires on page 5-52andIn¯ation - Tire Pressure on page 5-61.
If your vehicle does not have the Tire and Loading
Information label, the Certi®cation/Tire label shows the
tire size and recommended in¯ation pressures
needed to obtain the Gross Vehicle Weight Rating
(GVWR) and the Gross Axle Weight Rating (GAWR) for
the front and rear axles. See ªCerti®cation/Tire Labelº
later in this section.
Steps for Determining Correct Load Limit
1. Locate the statement ªThe combined weight of
occupants and cargo should never exceed XXX
poundsº on your vehicle placard.
2. Determine the combined weight of the driver and
passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and
passengers from XXX kilograms or XXX pounds.4. The resulting ®gure equals the available amount of
cargo and luggage load capacity. For example, if
the ªXXXº amount equals 1400 lbs. and there will be
®ve 150 lb. passengers in your vehicle, the
amount of available cargo and luggage load
capacity is 650 lbs. (1400-750 (5 x 150) =
650 lbs.).
5. Determine the combined weight of luggage and
cargo being loaded on the vehicle. That weight
may not safely exceed the available cargo
and luggage load capacity calculated in Step 4.
6. If your vehicle will be towing a trailer, the load from
your trailer will be transferred to your vehicle.
Consult this manual to determine how this reduces
the available cargo and luggage load capacity of
your vehicle. See
Towing a Trailer on page 4-35for
important information on towing a trailer, towing
safety rules and trailering tips.

Refer to your vehicle's tire and loading information label
for speci®c information about your vehicle's capacity
weight and seating positions. The combined weight of
the driver, passengers and cargo should never
exceed your vehicle's capacity weight.
Certi®cation/Tire Label
The Certi®cation/Tire label in your vehicle will look
similar to this example.
The Certi®cation/Tire label is found on the rear edge of
the driver's door. The label shows the size of your
original tires and the in¯ation pressures needed to obtain
the gross weight capacity of your vehicle.
This is called the Gross Vehicle Weight Rating (GVWR).
The GVWR includes the weight of the vehicle, all
occupants, fuel, cargo and tongue weight, if pulling a
trailer. Example 3
4-33

Payload
The Payload Capacity is shown on the Certi®cation/Tire
label. This is the maximum load capacity that your
vehicle can carry. Be sure to include the weight of the
people inside as part of your load. If you added any
accessories or equipment after your vehicle left
the factory, remember to subtract the weight of these
things from the payload. Your dealer can help you
with this.
Trailering Package
There is a load rating which includes the weight of the
vehicle and the trailer it tows. This rating is called
the Gross Combination Weight Rating (GCWR).
When you weigh your trailer, be sure to include the
weight of everything you put in it. And, remember
to ®gure the weight of the people inside the vehicle as
part of your load.
Add-On Equipment
When you carry removable items, you may need to put
a limit on how many people you carry inside your
vehicle. Be sure to weigh your vehicle before you buy
and install the new equipment.
Towing a Trailer
{CAUTION:
If you do not use the correct equipment and
drive properly, you can lose control when you
pull a trailer. For example, if the trailer is too
heavy, the brakes may not work well Ð or even
at all. You and your passengers could be
seriously injured. Pull a trailer only if you have
followed all the steps in this section. Ask your
dealer for advice and information about towing
a trailer with your vehicle.
Notice:Pulling a trailer improperly can damage
your vehicle and result in costly repairs that would
not be covered by your warranty. Always follow
the instructions in this section and check with your
dealer for more information about towing a trailer
with your vehicle.
To identify the trailering capacity of your vehicle, you
should read the information in ªWeight of the Trailerº that
appears later in this section.
4-35

The Gross Combined Weight Rating (GCWR) is the
total allowable weight of the completely loaded vehicle
and trailer including any passengers, cargo equipment
and conversion. The GCWR for your vehicle should not
be exceeded.
You can ask your dealer for our trailering information or
advice, or you can write us at the address listed in
your Warranty and Owner Assistance Information

Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important weight
to measure because it affects the total or gross weight
of your vehicle. The Gross Vehicle Weight (GVW)
includes the curb weight of the vehicle, any cargo you
may carry in it, and the people who will be riding in
the vehicle. If you have a lot of options, equipment,
passengers or cargo in your vehicle, it will reduce the
tongue weight your vehicle can carry, which will
also reduce the trailer weight your vehicle can tow. And
if you will tow a trailer, you must add the tongue load
to the GVW because your vehicle will be carryingthat weight, too. See
Loading Your Vehicle on page 4-30for more information about your vehicle's maximum
load capacity.
The trailer tongue weight (A) should be 10 percent to
15 percent of the total loaded trailer weight, up to
a maximum of 200 lbs (92 kg) with a weight carrying
hitch. The trailer tongue weight (A) should be 10 percent
to 15 percent of the total loaded trailer weight, up to
a maximum of 750 lbs (341 kg) with a weight
distributing hitch.
