1996 CHEVROLET SUBURBAN Owners Manual

Run your engine only as long as you must. This saves fuel. When you run
the engine, make it
go a little faster than just idle. That is, push the
accelerator slightly. This uses less fuel for the heat
that you get and it keeps
the battery (or batteries) charged. You will need a well-charged battery
(or
batteries) to restart the vehicle, and possibly for signaling later on with your
headlights. Let the heater
run for awhile.
If you have a diesel engine, you may have
to run it at a higher speed to get
enough heat. Then, shut the engine off and close the window almost all the
way to preserve the heat. Start the engine again and repeat
this only when
you feel really uncomfortable from the cold. But do it as little as possible.
Preserve the fuel
as long as you can. To help keep warm, you can get out of
the vehicle and do some fairly vigorous exercises every half
hour or so until
help
comes.
Power Winches
If you wish to use a power winch on your vehicle, only use it when your
vehicle
is stationary or anchored.
I NOTICE:
Using a power winch with the transmission in gear may damage
the transmission. When operating a power winch, always leave
the transmission in NEUTRAL
(N).
Use the regular brakes, set the parking brake, or block the wheels to keep
your vehicle from rolling.

Power Take-Off (PTO)
NOTICE:
If you have a PTO that will exceed 35 horsepower installed on
your vehicle, it could damage the transfer case or transmission.
When having a PTO installed on your vehicle, make sure that it
will not exceed
35 horsepower.
Before using a power take-off, refer to the manufacturer’s or installer’s
instructions.
NOTICE:
Using a PTO while operating in one place before the vehicle has
reached normal operating temperature can damage the transfer
case or transmission.
If you will be using the PTO while
operating in one place, drive and warm up the vehicle before
using the PTO.
To engage a power take-off
1. Set the parking brake.
2. Shift the transmission into NEUTRAL (N).
3. Hold the clutch pedal down and engage the power take-off.
NOTICE:
Using a PTO for more than four hours without driving your
vehicle can damage the transfer case or transmission.
If using a
PTO for more than four hours without driving your vehicle,
drive your vehicle for
a while to allow the transfer case and
transmission to cool.
If you are going to drive the vehicle, shift the transmission into the gear
you want. Then shift the transfer case into the range you want
(if you
have four-wheel drive), apply the regular brakes and release the
parking brake.
4. Release the clutch (and the regular brakes) as you normally would.
When
you release the clutch, the power take-off will start.

Loading Your Vehicle
I
PSI/KPA (COLD)
~ SEE OWNER'S MANUAL FOR ADDITIONAL INFORMATION
The CertificatiodTire 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 Certificatiodl'ire 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 GAWR for either the front
or rear axle.
And, if you do have a heavy load, you should spread it out.
.Using heavier suspension components to get added durability might not
change your weight ratings. Ask your dealer to help you load your vehicle
the right way.
If your vehicle is equipped for front-end equipment (a snow plow, for
example), the front suspension may have been adjusted (raised) to level the
vehicle when the equipment was installed. If the front suspension was
adjusted, you must re-adjust the front suspension after the equipment is
removed to avoid possible front suspension damage. Adjust the front
suspension
to original design specifications for your particular model.

I NOTICE:
Your warranty does not cover parts or components that fail
because of overloading.
If you put things inside your vehicle-like suitcases, tools, packages, or
anything else-they go as fast as the vehicle goes. If you have to stop
or
turn quickly, or if there is a crash, they’ll keep going.
There’s also important loading information for off-road driving in this
manual. See “Loading Your Vehicle”
in the Index.

Towing a Trailer
NOTICE:
Pulling a trailer improperly can damage your vehicle and result
in costly repairs not covered by your warranty.
To pull a trailer
correctly, follow the advice in this part, and see your
GM dealer
for important information about towing a trailer with your
vehicle.
Most vehicles are ready for some trailer towing. If yours was built with
trailering options, as many are, it’s ready for heavier trailers. But trailering
is different than just driving your vehicle by itself. Trailering means changes
in handling, durability, and fuel economy. Successful, safe trailering takes
correct equipment, and
it has to be used properly.
That’s the reason for this part.
In it are many time-tested, important
trailering tips and safety rules. Many of these are important for your safety
and that of your passengers.
So please read this section carefully before you
pull a trailer.

There are many different laws, including speed limit restrictions,
having to do
with trailering. Make sure your rig will be legal, not only
where you live but also where you’ll be driving.
A good source for this
information can be state or provincial police.
Consider using a sway control
if your trailer will weigh 3,000 pounds
(1 362 kg) or less for a utility vehicle or, for a Suburban, 4,000 pounds
(1 800 kg) or less. You should always use a sway control if your trailer
will weigh more than
3,000 pounds (1 362 kg) for a utility vehicle or
4,000 pounds (1 800 kg) for a Suburban. You can ask a hitch dealer
about sway controls.
Don’t tow a trailer at all during the first
500 miles (800 km) your new
vehicle is driven. Your engine, axle or other parts could be damaged.
Then, during
the first 500 miles (800 km) that you tow a trailer, don’t
drive over
50 mph (80 km/h) and don’t make starts at full throttle. This
helps your engine and other parts of your vehicle wear in at the heavier
loads.
If you have
an automatic transmission, you should use DRIVE (3) (or, as
you need to, a lower gear) when towing
a trailer. Operating your vehicle
in DRIVE (3) when towing a trailer will minimize heat build-up and
extend the life of your transmission.
If you have a manual transmission
and you are towing a trailer, it’s better not to use
FIFTH (5) gear. Just
drive in FOURTH (4) gear (or. as vou need to. a lower pearl

Three important considerations have to do with weight:
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

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).
