1995 GMC SIERRA check engine

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).
3. 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!
NOTICE:
If you leave your radio on, it could be badly damaged. The
repairs wouldn’t be covered by your warranty.
4. Open the hoods and locate the batteries. Find the positive (+) and
negative
(-) terminals on each battery.
A CAUTION:
Using a match near a battery can cause battery gas to explode.
People have been hurt doing this, and some have been blinded.
Use
a flashlight if you need more light.
Be sure the batteries have enough
water. You don’t need to add
water to the Delco Freedom@ battery (or batteries) installed in
every new
GM vehicle. But if a battery has filler caps, be sure
the right amount of fluid is there.
If it is low, add water to take
care
of that first. If you don’t, explosive gas could be present.
Battery fluid contains acid that can burn you. Don’t get
it on
you.
ff you accidentally get it in your eyes or on your skin, flush
the place with water and get medical help immediately.
5. 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.

Fuel Requirements
NOTICE:
Diesel fuel or fuel additives not recommended in this manual
could damage your fuel system and engine. Your warranty
wouldn’t cover this damage. And:
Diesel fuel that has been mixed with engine oil could damage
your engine and emission controls. Always check with your
service station operator to make sure his diesel fuel has not \
been mixed with engine oil.
If you ever run out of diesel fuel, it can be difficult to restart
your engine. “Running Out of Fuel,” later in this section, tells
you how to get it started again.
To avoid all this, try never to
let your tank get empty.
What Fuel to Use
For best results, use Number 2-D diesel fuel year-round (above and below
freezing conditionsj as oil companies blend Number
2-D fuel to address
climate differences. Number
1-D diesel fuel may be used in very cold
temperatures (when
it stays below 0°F or -18°C); however, it will produce
a power and fuel economy loss. The use of Number I-D diesel fuel in warm
or hot climates may result in stalling, poor starting when the engine is hot
and
may damage the fuel injection system.
Diesel fuel may foam when you
fill your tank. This can cause the automatic
pump nozzle to shut off, even though your tank isn’t
full. If this happens,
just wait for the foaming to stop and then continue to
fill your tank.
A CAUTION:
Heat coming from the engine may cause the fuel to expand and \
force the fuel out of your tank.
If something ignites the fuel, a
fire could start and people could be burned. To help avoid this,
fill your fuel tank only until the automatic nozzle shuts
off.
Don’t try to “top it off.”

let you know if you
ever do get water in
your fuel.
If you drive when this warning light is on, you can damage your
fuel injection system and your engine.
If the light comes on right
after you refuel,
it means water was pumped into your fuel tank.
Turn
off your engine immediately. Then, have the water drained
at once.

Fuels in Foreign Countries (Gasoline Engines)
If you plan on driving in another country outside the U.S. or Canada,
unleaded fuel may be hard to find.
Do not use leaded gasoline. If you use
even one tankful, your emission controls won’t work well or at all. With
continuous use, spark plugs can get fouled, the exhaust system can corrode,
and your engine
oil can deteriorate quickly. Your vehicle’s oxygen sensor
will be damaged.
All of that means costly repairs that wouldn’t be covered
by your warranty.
To check on fuel availability, ask an auto club, or contact a major oil
company that does business in the country where you’ll be driving.
You can also write
us at the following address for advice. Just tell us where
you’re going and give your Vehicle Identification Number
(VIN).

A CAUTION:
Gasoline vapor is highly flammable. It burns violently, and that
can cause very bad injuries. Don’t smoke
if you’re near gasoline
or refueling your vehicle. Keep sparks, flames, and smoking
materials away from gasoline.

Engine Oil (Gasoline Engines)
It’s a good idea to check your engine oil every time you get fuel. In order to
get an accurate reading, the oil must be warm and the vehicle must be on
level ground.
Turn
off the engine
and give the oil
a few
minutes to drain back
into the oil pan.
If you
don’t, the
oil dipstick
might not show the
actual level.
To Check Engine Oil
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 down.

Engine Coolant Heater
An engine coolant heater can be a big help if you have to park outside in
very cold weather, 0°F (-1 8OC) or colder. If your vehicle has this option,
see “Engine Coolant Heater’’ in the Index.
What to Do with Used Oil
Did you know that used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer? Don’t let used oil stay
on your skin for very long. Clean your skin and nails with soap and water,
or a good hand cleaner. Wash or properly throw away clothing or rags
containing used engine oil. (See the manufacturer‘s warnings about the use
and disposal of
oil products.)
Used oil can be a real threat to
the environment. If you change your own oil,
be sure to drain all free-flowing oil from the filter before disposal. Don’t
ever dispose
of oil by putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies
of water. Instead. recycle it by taking it to
a place that collects used oil. If you have a problem properly disposing of
your used oil, ask your dealer, a service station or a local recycling center
for help.
