PONTIAC BONNEVILLE 2005 Owners Manual

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 Engine Oil
Life System
The Engine Oil Life System calculates when to change
your engine oil and lter 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 DIC 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 Engine
Oil Life System, do the following:
1. Display OIL LIFE on the DIC.
2. Press and hold the RESET button for more than
ve seconds. The oil life will change to 100%.
3. Turn the key to OFF.
If the ENGINE OIL CHANGE SOON DIC message
comes back on when you start your vehicle, the Engine
Oil Life System has not reset. Repeat the procedure.
What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Do not 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 dispose of 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
lter 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
(3.8L V6 Engine)
SeeEngine Compartment Overview on page 5-12
for the location of the engine air cleaner/lter.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/lter every 15,000 miles
(25 000 km) and replace every 45,000 miles
(75 000 km). If you are driving in dusty/dirty conditions,
inspect the lter at each engine oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/lter remove the lter from the
vehicle and lightly shake the lter to release loose
dust and dirt. If the lter remains caked with dirt, a new
lter is required.
To inspect or replace the engine air cleaner/lter do
the following:
1. Loosen the two clips on top of the engine air
cleaner/lter housing and lift the lter cover tabs out
of the housing.
2. Push the housing cover toward the engine,
compressing the hose.
3. Pull out the lter. Inspect or replace the engine air
cleaner/lter.
5-22

4. To reinstall the housing cover, make sure the lter
cover tabs position through the slots in the housing.
A notch on the sides of the lter cover will indicate
the correct engagement.
5. Fasten the two clips on the top of the housing when
you are nished.
{CAUTION:
Operating the engine with the air cleaner/lter
off can cause you or others to be burned.
The air cleaner not only cleans the air; it helps
to stop ame if the engine backres. If it is
not there and the engine backres, you could
be burned. Do not drive with it off, and be
careful working on the engine with the air
cleaner/lter off.
Notice:If the air cleaner/lter is off, a backre can
cause a damaging engine re. And, dirt can easily get
into your engine, which will damage it. Always have
the air cleaner/lter in place when you are driving.

while pulling toward you. This is necessary due to
the three tabs located on the rear of the cover.3. Remove the engine air cleaner/lter element and
any loose debris that may be found in the air
cleaner base.
4. Inspect or replace the air lter element.

Automatic Transaxle Fluid
(3.8L V6 Engine)
When to Check and Change
A good time to check your automatic transaxle uid
level is when the engine oil is changed.
Change both the uid and lter every 50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police or
delivery service.
If you do not use your vehicle under any of these
conditions, change the uid and lter at 100,000 miles
(166 000 km).
SeePart A: Scheduled Maintenance Services on
page 6-4.
5-25

How to Check
Because this operation can be a little difficult, you
may choose to have this done at the 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 uid can damage the
transaxle. Too much can mean that some of the
uid could come out and fall on hot engine or
exhaust system parts, starting a re. Too little uid
could cause the transaxle to overheat. Be sure
to get an accurate reading if you check the
transaxle uid.
Wait at least 30 minutes before checking the transaxle
uid level if you have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic — especially in hot weather.
While pulling a trailer.To get the right reading, the uid should be at normal
operating temperature, which is 180°F to 200°F
(82°C to 93°C).
Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above 50°F
(10°C). If it is colder than 50°F (10°C), you may have to
drive longer.
Checking the Fluid Level
Prepare your vehicle as follows:
Park your vehicle on a level place. Keep the
engine running.
With the parking brake applied, place the shift lever
in PARK (P).
With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds in each range. Then, position the shift
lever in PARK (P).
Let the engine run at idle for three to ve minutes.
5-26

Then, without shutting off the engine, follow these steps:
The transaxle uid dipstick
top is a round, red loop
and is located next to the
brake master cylinder
behind the engine block.
SeeEngine Compartment
Overview on page 5-12
for more information
on location.
1. Pull out the dipstick and wipe it with a clean rag or
paper towel.
2. Push it back in all the way, wait three seconds and
then pull it back out again.3. Check both sides of the dipstick, and read the
lower level. The uid level must be in the
cross-hatched area.
4. If the uid level is in the acceptable range,
push the dipstick back in all the way.
5-27

How to Add Fluid
Refer to the Maintenance Schedule to determine
what kind of transaxle uid to use. SeePart D:
Recommended Fluids and Lubricants on page 6-24.
If the uid level is low, add only enough of the proper
uid to bring the level into the cross-hatched area
on the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough uid at the
dipstick hole to bring it to the proper level.
It does not take much uid, generally less than
one pint (0.5 L).Do not overll.
Notice:Use of automatic transaxle uid labeled
other than DEXRON
®-III, Approved for the
H-Specication, may damage your vehicle, and the
damages may not be covered by your warranty.
Always use automatic transaxle uid labeled
DEXRON
®-III, Approved for the H-Specication.
3. After adding uid, recheck the uid level as
described under “How to Check,” earlier in
this section.
4. When the correct uid level is obtained, push the
dipstick back in all the way.

Then, without shutting off the engine, follow these steps:
The transaxle uid cap is
located next to the radiator
hose and below the
engine air cleaner/lter
assembly on the driver’s
side of the vehicle.
SeeEngine Compartment
Overview on page 5-12
for more information
on location.
1. After removing the engine air cleaner/lter assembly
to reach the transaxle uid cap, turn the cap
counterclockwise to remove. Pull out the dipstick
and wipe it with a clean rag or paper towel.
2. Push it back in all the way, wait three seconds, and
then pull it back out again.3. Check both sides of the dipstick, and read the
lower level. The uid level must be in the
cross-hatched area.
4. If the uid level is in the acceptable range, push the
dipstick back in all the way and turn the handle
clockwise. Reinstall the engine air cleaner/lter
assembly.
