load capacity CHEVROLET ASTRO PASSENGER 1994 1.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine Here are things some owners ask about. None of these indicate a problem
with your fuel gage:
0 At the gas station, the gas pump shuts off before the gage r\
eads full.
The fuel tank will take either a little more or a little less fuel to fill up
than the gage shows.
The gage moves a little when you turn a corner or speed up.
The gage doesn’t go back to empty when you turn off the ignition.
For your fuel tank capacity, see the Index under “Fluid Capacities.”
Oil Pressure Gage
Standard Cluster Digital Cluster
The oil pressure gage shows the engine oil pressure in psi (pounds pe\
r
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 dangerous\
ly low oil
level or other problems causing low oil pressure.
On the digital cluster, a box around the oil pressure symbol \
will begin to
flash when the oil pressure
is low.

If you have the
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
luggage carrier may damage your vehicle. When you carry large
things, never let them hang over the rear or the sides of your
vehicle. Load your cargo
so that it rests on the slats and does not
scratch or damage the vehicle. Put the cargo against the side
rails and fasten it securely to the luggage carrier. Put the main
weight as far forward as you can.
Don’t exceed the maximum vehicle capacity when loading your vehicle. For
more information on vehicle capacity and loading, see “Loading Your
Vehicle”
in the Index.
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.

Downloaded from www.Manualslib.com manuals search engine Weight of the Trailer
How heavy can a trailer safely be?
It depends on how you plan to use your rig. For example, speed, altitude,
road grades, outside temperature and how much your vehicle is used to pull
a trailer are all important. And,
it can also depend on any special equipment
that you have on your vehicle.
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 Booklet.
In Canada, write to General Motors of Canada Limited, Customer
Assistance Center,
1908 Colonel Sam Drive, Oshawa, Ontario LlH 8P7.
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. And if you will
tow a trailer, you must add the tongue load to the
GVW because your
vehicle will be carrying that weight, too. See “Loading Your Vehicle”
in the
Index for more information about your vehicle’s maximum load capacity.
A B
If you’re using a “dead-weight” hitch, the trailer tongue (A) should weigh
10% of the total loaded trailer weight (B). If you have a
“weight-distributing” hitch, the trailer tongue (A) should weigh
12% of the
total loaded trailer weight (B).
After you’ve loaded your trailer, weigh the trailer and then the tongue,
separately, to see if the weights are proper. If they aren’t, you may be able to
get them right simply by moving some items around
in the trailer.

Pull out the dipstick and clean it with a paper towel or cloth, then push it
back in all the way. Remove it again, keeping
the tip lower.
I
When to Add Oil
If the oil is at or below the ADD line, then you’ll need to add some oil. But
you must use the right kind. This section explains what kind of oil to use.
For crankcase capacity, see “Capacities and Specifications” \
in the Index.
L
NOTICE:
Don’t add too much oil. If your engine has so much oil that the
oil level gets above the cross-hatched area that shows the pro\
per
operating range, your engine could be damaged.

(SERVICE ENGINE SOON )
This light on your instrument cluster lets you know when your emission
system needs service. The light will come on briefly when you start your
engine to let you know that the system is working. If it does not come on
when you start your engine, or if it comes
on and stays on while you’re
driving, your system may need service. Your vehicle should still be
driveable, but you should have your system serviced right away.
Loading Your Vehicle
The Certificationire
label is found on the
rear edge of the
driver’s door. The
label shows the size of
your original tires and
the inflation pressures
needed to obtain the
gross weight capacity
of your vehicle.
This is called the GVWR (Gross Vehicle Weight Rating). The GVWR
includes the weight of the vehicle, all occupants, fuel and cargo.
The CertificatiodTire label
also tells you the maximum weights for the
front and rear axles, called Gross Axle Weight Rating (GAWR). To find out
the actual loads on your front and rear axles, you need
to go to a weigh
station and weigh your vehicle. Your dealer can help you with this. Be sure
to spread out your load equally on both sides of the centerline.
Never exceed
the GVWR for your vehicle, or the Gross Axle Weight Rating
(GAWR) for either the front or rear axle.

Downloaded from www.Manualslib.com manuals search engine Payload
The Payload Capacity is shown on the CertificationRire 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
If your vehicle comes with the Trailering Package, there is also 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 figure the weight of the people inside as
part of your load.
Your dealer can help
you determine your GCWR.

Downloaded from www.Manualslib.com manuals search engine Each new wheel should have the same load carrying capacity, diameter,
width, offset, and be mounted the same way as the
one it replaces.
If you need to replace any of your wheels, wheel bolts, or wheel nuts,
replace them only with new
GM original equipment parts. This way, you
will be sure to have the right wheel, wheel bolts, and wheel nuts
for your
GM model.
NOTICE:
The wrong wheel can also cause problems with bearing life,
brake cooling, speedometer/odometer calibration, headlight aim,
bumper height, vehicle ground clearance, and tire or tire chain\

clearance to the body and chassis.

Not all air conditioning refrigerants are the same. If the air conditioning
system in your vehicle needs refrigerant, be sure the proper refrigerant is
used. If you’re not sure, ask your
