1995 CHEVROLET SUBURBAN engine

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.

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

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have extra wiring (included in
the optional trailering package). The green arrows
on your instrument panel
will flash whenever
you signal a turn or lane change. Properly hooked up,
the trailer lamps will
also flash, telling other drivers you’re about to turn,
change lanes or stop.
When towing a trailer, the green arrows on your instrument panel will flash
for turns even if the bulbs
on the trailer are burned out. Thus, you may think
drivers behind you are seeing your signal when they are not. It’s important
to check occasionally to be sure the trailer bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start down a long or steep
downgrade. If
you don’t shift down, you might have to use your brakes so
much that they would get hot and no longer work well.
On
a long uphill grade, shift down and reduce your speed to around 45 mph
(70 kdh) to reduce the possibility of engine and transmission overheating.
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 you need
to,
a lower gear).
When towing at high altitude
on steep uphill grades, consider the following:
Engine coolant will boil at a lower temperature than at normal altitudes. If
you turn your engine off immediately after towing at high altitude on steep
uphill grades, your vehicle may show signs similar
to engine overheating.
To avoid this, let the engine run while parked (preferably on level ground)
with the automatic transmission
in PARK (P) (or the manual transmission
out of gear and the parking brake applied) for a few minutes before turning
the engine off.
If you do get the overheat warning, see “Engine
Overheating” in the Index.
Parking on Hills
You really should not park your vehicle, with a trailer attached, on a hill. If
something goes wrong, your rig could start to move. People can be injured,
and both your vehicle and
the trailer can be damaged.
But
if you ever have to park your rig on a hill, here’s how to do it:
1. Apply your regular brakes, but don’t shift into PARK (P) yet, or in gear
for a manual transmission.
ProCarManuals.com

2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the
chocks absorb the load.
4. Re-apply the regular brakes. Then apply your parking brake, and then
shift to
PARK (P), or REVERSE (R) for a manual transmission.
5. If you have a four-wheel-drive vehicle, be sure the transfer case is in a
drive gear-not
in NEUTRAL (N).
6. Release the regular brakes.
When You Are Ready to Leave After Parking on a Hill
1. Apply your regular brakes and hold the pedal down while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.

Maintenance When Trailer Towing
Your vehicle will need service more often when you’re pulling a trailer. See
the Maintenance Schedule for more on this. Things that are especially
important
in trailer operation are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belt, cooling system, an\
d brake
adjustment. Each
of these is covered in this manual, and the Index will help
you find them quickly. If you’re trailering, it’s a good idea to review these
sections before you start your trip.
Check periodically to see
that all hitch nuts and bolts are tight.

NOTICE:
Ignoring these steps could result in costly damage to your
vehicle that wouldn’t be covered by your vehicle warranty.
Trying to start your vehicle by pushing or pulling it could
damage your vehicle, even if you have a manual transmission.
And if you have an automatic transmission, it won’t start that
way.
To Jump Start Your Vehicle
Check the other vehicle. It must have a 12-volt battery with a negative
ground system.
NOTICE:
If the other system isn’t a 12-volt system with a negative
ground, both vehicles can be damaged.
If you have a diesel engine vehicle with two batteries (or more), you
should know before you begin that, especially
in cold weather, you may
not be able to get enough power from a single battery in another
vehicle
to start your diesel engine.
If your vehicle has more than one battery, use the battery that’s on the
passenger side
of the vehicle - this will reduce electrical resistance.
Get the vehicles close enough so the jumper cables can reach, but be
sure the vehicles aren’t touching each other. If they are, it could cause a
ground connection you don’t want. You wouldn’t be able to start your
vehicle, and the bad grounding could damage the electrical systems.
You could
be injured if the vehicles roll. Set the parking brake firmly on
each vehicle. Put
an automatic transmission in PARK (P) or a manual
transmission in NEUTRAL (N). If you have a four-wheel-drive vehicle, be
sure the transfer case is not in NEUTRAL (N).

Turn off the ignition on both vehicles. Turn off all lights that aren’t
needed, and radios. This will avoid sparks and help save both batteries.
And it could
save your radio!
I NOTICE:
If you leave your radio on, it could be badly damaged. The
repairs wouldn’t be covered by your warranty.
Open the hoods and locate the batteries. Find the positive (+) and
negative
(-) terminals on each battery.
Check that the jumper cables don’t have loose or missing insulation. If
they do, you could get a shock. The vehicles could be damaged, too.
Before
you connect the cables, here are some basic things you should
know. Positive
(+) will go to positive (+) and negative (-) will go to
negative (-) or a metal engine part. Don’t connect (+) to (-) or you’ll
get a short that would damage the battery and maybe other parts, too.

Good Battery (-) Heavy Metal Engine Part
Attach the cable at least 18 inches (45 cm) away from the dead battery,
but not near engine parts that move. The electrical connection is just as
good there, but the chance
of sparks getting back to the battery is much
less.
Now start the vehicle with the good battery and run the engine for
awhile.
0 Try to start the vehicle with the dead battery.
If it won’t start after a few tries, it probably needs service.
Remove Cables in this Order:
2 3 1. Heavy Metal
2. Good Battery (-)
