change the
fuel brand you use. It will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn
off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools
to fix any mechanical or electrical
problems that may have developed.
Oil Pressure Gage
The oil pressure gage shows
the engine oil pressure in
psi (pounds per 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
dangerously low oil level or other problems causing low
oil pressure.
I
Don’t keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire.
You or others could be burned.
Check your oil
as soon as possible and have your
vehicle serviced.

NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

Downloaded from www.Manualslib.com manuals search engine 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 km/h) to reduce the
possibility
of engine and transmission overheating.
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) for a few
minutes before turning
the engine off. If you do get the
overheat warning, see “Engine Overheating” in
the Index.

9. Remove any rust or dirt
from the wheel bolts, mounting surfaces and
spare wheel.
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could come
off and cause an accident. When you change a
wheel, remove any rust or dirt from the places
where the wheel attaches to the vehicle. In an
emergency, you can use
a cloth or a paper towel
to do this; but be sure to use a scraper or wire
brush later, if you need to, to get all the rust or
dirt off.
A CAI'TION:
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall
off, causing a serious accident.
10. Put on the spare tire. Put the nuts on by hand. Make
sure the cone-shaped end
is toward the wheel.
Tighten each
nut by hand until the wheel is held
against the hub.
If a nut can't be turned by hand,
use
the extension and see your dealer as soon
as possible.

Downloaded from www.Manualslib.com manuals search engine When to Add Oil
If the oil is at or below the ADD line, then you’ll need
to add at least one quart
of oil. But you must use the
right kind. This part explains what kind of oil to use. For
crankcase capacity, see “Capacities and Specifications’’
in the Index.
What Kind of Oil to Use
Oils recommended for your vehicle can be identified by
looking for the “Starburst” symbol. This symbol
indicates that the
oil has been certified by the American
Petroleum Institute (APT).
Do not use any oil which
does
not carry this Starburst symbol.
~ 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 proper
operating range,
your engine could be damaged.
Be sure to fill it enough to put the level somewhere in
the proper operating range. Push the dipstick all the way
back in when you’re through. If you
change your own oil,
be sure you use
oil that has
the Starburst symbol
on the
front
of the oil container.
If you have your oil changed for you, be sure the oil put
into your engine is American Petroleum Institute
certified for gasoline engines.
You should also use the proper viscosity oil for your
vehicle, as shown
in the following chart:

Downloaded from www.Manualslib.com manuals search engine Engine Oil Additives
Don’t add anything to your oil. Your GM dealer is ready
to advise if you think something should be added.
When to Change Engine Oil
If any one of these is true for you, use the short tripkity
maintenance schedule:
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrier on top of
your vehicle.
The vehicle is used for delivery service, police, taxi
or other commercial application.
Driving under these conditions causes engine oil
to
break down sooner. If any one of these is true for your
vehicle, then you need to change your oil and filter
every
3,000 miles (5 000 km) or 3 months -- whichever
occurs first. If
none
of them is true, use the long triphighway
maintenance schedule. Change the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
occurs first. Driving a vehicle with a
fully warmed
engine under highway conditions causes engine
oil to
break down slower.
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.

When to Check and Change
A good time to check your automatic transmission fluid
level is when
the engine oil is changed.
Change both the fluid and filter every
15,000 miles
(25 000 km) if the vehicle is mainly driven under one or
more
of these conditions:
0 In heavy city traffic where the outside temperature
In hilly or mountainous terrain.
0 When doing frequent trailer towing.
regularly reaches
90 OF (32 ” C) or
higher.
Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, change the fluid and filter every
30,000 miles
(50 000 km).
See “Scheduled Maintenance Services” in the Index.
How to Check
Because this operation can be a little difficult, you may
choose to have this done at your
GM dealership
Service Department.
If you do it yourself, be sure to follow all the instructions
here, or you could get
a false reading on the dipstick.
NOTICE:
Too much or too little fluid can damage your
transmission.
Too much can mean that some of
the fluid could come out and fall on hot engine
parts or exhaust system parts, starting a fire. Be
sure to get an accurate reading if you check your
~ transmission fluid.
Wait at least 30 minutes before checking the
transmission fluid level if you have been driving:
0 When outside temperatures are above 90°F (32°C).
0 At high speed for quite a while.
0 In heavy traffic -- especially in hot weather.
0 While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which
is 180°F to 200°F
(82°C to 93°C).

When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often
to check the lubricant and when to change it. See
“Scheduled Maintenance Services” in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole,
you’ll need
to add some lubricant. Add enough lubricant
to raise
the level to the bottom of the filler plug hole. Refer to the Maintenance Schedule to
determine what
kind of lubricant to use. See “Recommended Fluids and
Lubricants”
in the Index.
Engine Coolant
The cooling s stem in your vehicle is filled with new
DEX-COOL
J engine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km) whichever occurs first, if you add only
DEX-COOL’ extended life coolant.
The following explains your cooling system and how to
add coolant when
it is low. If you have a problem with
engine overheating, see “Engine Overheating”
in
the Index.
A 50/50 mixture of water and DEX-COOL@ coolant for
your vehicle
will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
0 Let the warning lights and gages work as they should.

NOTICE:
When adding coolant, it is important that you use
only
DEX-COOL’ (silicate-free) coolant.
If coolant other than DEX-COOL’ is added to
the system, premature engine, heater core or radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the
use
of coolant other than DEX-COOL@ is not
covered by your new vehicle warranty.
What to Use
Use a mixture of one-half clean wuter (preferably
distilled) and one-half
DEX-COOL@ coolant which
won’t damage aluminum parts.
If you use this mixture,
you don’t need to add anything else.
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix will, Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you or
others could be burned, Use a
50/50 mix of clean
water and DEX-COOL@ antifreeze.
