2002 PONTIAC BONNEVILLE oil change

2-29
NOTICE:
Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer. If you don't,
your engine might not perform properly.
Engine Coolant Heater (If Equipped)
In very cold weather, 0
F (-18
C) or colder, the engine
coolant heater can help. You'll get easier starting and
better fuel economy during engine warm
-up. Usually, the
coolant heater should be plugged in a minimum of four
hours prior to starting your vehicle. At temperatures above
32
F (0
C), use of the coolant heater is not required.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The engine coolant heater cord is located on
the passenger's side of the vehicle, above the
headlamp assembly.3. Plug it into a normal, grounded 110
-volt AC outlet.
CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three
-prong
11 0
-volt AC outlet. If the cord won't reach, use a
heavy
-duty three-prong extension cord rated for
at least 15 amps.
4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it away
from moving engine parts. If you don't, it could
be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact
your dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

Fuel Range: Press the SELECT button until the display
shows FUEL RANGE. The fuel range will calculate the
remaining distance you can drive without refueling. This
calculation is based on the average fuel economy for the
last 25 miles (40.25 km) driven, and the fuel remaining
in the fuel tank. If the fuel range drops below 40 miles
(64.4 km), the display will show FUEL RANGE LOW.
The RESET button does not function in this mode.
Fuel Used: Press the SELECT button until the display
shows FUEL USED. The value indicates how much fuel
has been used since the last reset. Don't confuse fuel
used with the amount of fuel in your tank. To learn how
much fuel will be used from a specific starting point,
press the RESET button for five seconds while the fuel
used is displayed on the DIC.
Battery Volts: On vehicles with a supercharged engine,
press the SELECT button until the display shows
BATTERY VOLTS. If the voltage is normal the display
will show BATTERY ## VOLTS. If the voltage drops
below 10.5 volts for 30 seconds, the battery volts
display will show BATTERY LOW. If the voltage is
above 16.2 volts for 30 seconds, the battery volts display
will show BATTERY HIGH. If the display shows the
high or low message, you need to have your battery
and/or electrical system checked.GM Oil Life System
: Press the SELECT button until
OIL LIFE appears in the display. The OIL LIFE
NORMAL display will show an estimate of the oil's
remaining useful life. When the oil life index is less than
10%, an ENGINE OIL CHANGE SOON message will
be displayed and the oil life display will show OIL LIFE
CHANGE. When you have the oil changed according to
the maintenance schedule, you will have to reset the Oil
Life System. To reset the Oil Life System, see ªOil Life
Systemº in the Index. Also, see ªEngine Oil, When to
Changeº and ªMaintenance Scheduleº in the Index.
Tire Pressure Status: Press the SELECT button until
TIRE PRESSURE appears in the display. TIRE
PRESSURE NORMAL is displayed when the Check
Tire Pressure System believes your vehicle's tire
pressures are normal. If a potential problem is detected,
the display will show CHECK TIRE PRESSURE and
the tire pressure status will show TIRE PRESSURE
LOW. If you see the CHECK TIRE PRESSURE
message, you should stop as soon as you can and check
all your tires for damage. (If a tire is flat, see ªIf a Tire
Goes Flatº in the Index.) Also check the tire pressure in
all four tires as soon as you can. See ªInflation
-- Tire
Pressureº and ªCheck Tire Pressure Systemº in
the Index.

it means there may be a problem with your stability
enhancement system. If you see this message, try to
reset the system (stop; turn off the engine; then start the
engine again). If the SERVICE STABILITY SYSTEM
message still comes on, it means there is a problem.
You should see your dealer for service. Reduce your
speed and drive accordingly.

7. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.
CAUTION:
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.
CAUTION:
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.
8. Place the compact spare tire on the
wheel
-mounting surface.

6-14 What Kind of Engine 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 (API). Do not use any
oil which does not carry this starburst symbol.
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:

6-15
SAE 10W-30 is best for your vehicle. However, you can
use SAE 5W
-30 if it's going to be colder than 60F
(16C) before your next oil change. When it's very cold,
you should use SAE 5W
-30. These numbers on an oil
container show its viscosity, or thickness. Do not use
other viscosity oils, such as SAE 20W
-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
starburst symbol. Failure to use the
recommended oil can result in engine damage not
covered by your warranty.
GM Goodwrench oil meets all the requirements for
your vehicle.
If you are in an area where the temperature falls below
-20F (-29C), consider using either an SAE 5W-30
synthetic oil or an SAE 0W
-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.
Engine Oil Additives
Don't add anything to your oil. The recommended oils
with the starburst symbol are all you will need for good
performance and engine protection.
When to Change Engine Oil (Vehicles
Without the GM Oil Life System)
If any one of these is true for you, use the short trip/city
maintenance schedule:

Most trips are less than 5 miles (8 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).

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.

6-16
If none of them is true, use the long trip/highway
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 will cause engine oil
to break down slower.
When to Change Engine Oil (Vehicles With
the GM Oil Life System
Option)
If so equipped, your vehicle has a computer system that
lets you know when to change the engine oil and filter.
This is based on engine revolutions and engine
temperature, and not on mileage. Based on driving
conditions, the mileage at which an oil change will be
indicated can vary considerably. For the oil life system
to work properly, you must reset the system every time
the oil is changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. An ENGINE OIL CHANGE SOON message
will come on. Change your oil as soon as possible
within the next two times you stop for fuel. It is possible
that, if you are driving under the best conditions, the oil
life system may not indicate that an oil change is
necessary for over a year. However, your engine oil and
filter must be changed at least once a year and at thistime the system must be reset. It is also important to
check your oil regularly and keep it at the proper level.
If the system is ever reset accidentally, you must change
your oil at 3,000 miles (5 000 km) since your last oil
change. Remember to reset the oil life system whenever
the oil is changed.
How to Reset the Oil Life System (Option)
The GM Oil Life System
calculates when to change
your engine oil and filter based on vehicle use. Anytime
your oil is changed, reset the system so it can calculate
when the next oil change is required. If a situation
occurs where you change your oil prior to an ENGINE
OIL CHANGE SOON message being turned on, reset
the system.
Always reset the engine oil life to 100% after every oil
change. It will not reset itself. To reset the Oil Life
System, do the following:
1. Display OIL LIFE on the DIC.
2. Press and hold the RESET button for more than five
seconds. The oil life will change to 100%.

6-17 What to Do with Used Oil
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 threat to the environment. If you
change your own oil, be sure to drain all the oil from
the filter before disposal. Never 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.
Engine Air Cleaner/Filter
The engine air cleaner/filter is in the engine
compartment on the driver's side of the vehicle. See
ªEngine Compartment Overviewº in the Index for more
information on location.
