What to Do with Used Oil
Used engine oil contains certain
elements that can 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 andwater, 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 used
oil, ask your dealer/retailer, a
service station, or a local recycling
center for help.
Engine Air Cleaner/Filter
SeeEngine Compartment
Overview on page 9-6for the
location of the engine air
cleaner/lter.
When to Inspect the Engine
Air Cleaner/Filter
Inspect the air cleaner/lter at the
MaintenanceIIintervals and replace
it at the rst oil change after each
50,000 mile (83 000 km) interval.
See “Schedule Maintenance”
in Service and Maintenance for
more information. If you are driving
in dusty/dirty conditions, inspect
the lter at each engine oil change.
Vehicle Service and Care 9-11
2008 - Pontiac G8 Owner Manual

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.
Automatic Transmission
Fluid
It is not necessary to check the
transmission uid level. A
transmission uid leak is the only
reason for uid loss. If a leak occurs,
take your vehicle to a dealer/retailer
and have it repaired as soon as
possible.
Change the uid and lter at the
intervals listed in the Maintenance
Schedule. SeeScheduled
Maintenance on page 11-4. Be sure
to use the transmission uid
listed inRecommended Fluids and
Lubricants on page 11-12.Notice:Use of the incorrect
automatic transmission uid may
damage your vehicle, and the
damages may not be covered by
your warranty. Always use the
automatic transmission uid
listed inRecommended Fluids
and Lubricants on page 11-12.
Engine Coolant
The cooling system in your vehicle is
lled with DEX-COOL®engine
coolant. This coolant is designed to
remain in your vehicle for ve years
or 150,000 miles (240 000 km),
whichever occurs rst, 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 on page 9-16.A 50/50 mixture of clean, drinkable
water and DEX-COOL
®coolant 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.
Let the warning lights and gages
work as they should.
Notice:Using coolant other than
DEX-COOL
®can cause premature
engine, heater core, or radiator
corrosion. In addition, the engine
coolant may require changing
sooner, at the rst maintenance
service after each 30,000 miles
(50 000 km) or 24 months,
whichever occurs rst. Any
repairs would not be covered by
the vehicle warranty. Always
use DEX-COOL
®(silicate-free)
coolant in the vehicle.

Maintenance
Requirements
Notice:Maintenance intervals,
checks, inspections, replacement
parts, and recommended uids
and lubricants as prescribed
in this manual are necessary to
keep your vehicle in good
working condition. Any damage
caused by failure to follow
scheduled maintenance might not
be covered by warranty.
Your Vehicle and the
Environment
Proper vehicle maintenance not only
helps to keep your vehicle in good
working condition, but also helps the
environment. All recommended
maintenance is important. Improper
vehicle maintenance can even affect
the quality of the air we breathe.
Improper uid levels or the wrong tire
ination can increase the level of
emissions from your vehicle. To help
protect our environment, and to keepyour vehicle in good condition, be
sure to maintain your vehicle
properly.
Using the Maintenance
Schedule
We want to help you keep your
vehicle in good working condition.
But we do not know exactly how you
will drive it. You might drive very
short distances only a few times a
week. Or you might drive long
distances all the time in very hot,
dusty weather. You might use your
vehicle in making deliveries. Or
you might drive it to work, to
do errands, or in many other ways.
Because of all the different ways
people use their vehicles,
maintenance needs vary. You might
need more frequent checks and
replacements. So please read the
following and note how you
drive. If you have any questions on
how to keep your vehicle in good
condition, see your dealer/retailer.This schedule is for vehicles that:
carry passengers and cargo
within recommended limits.
You will nd these limits on the
Tire and Loading Information
label. SeeLoading the Vehicle on
page 8-28.

(e)Make sure the safety belt
reminder light and safety belt
assemblies are working properly.
Look for any other loose or
damaged safety belt system parts. If
you see anything that might keep
a safety belt system from doing
its job, have it repaired. Have any
torn or frayed safety belts replaced.
Also see Airbag System Check
on page 1-31.
(f)Lubricate all key lock cylinders,
door hinges and latches, hood
hinges and latches and trunk lid
hinges and latches. More frequent
lubrication may be required
when exposed to a corrosive
environment. Applying silicone
grease on weatherstrips with a clean
cloth will make them last longer,
seal better, and not stick or squeak.
(g)Visually inspect belt for fraying,
excessive cracks, or obvious
damage. Replace belt if necessary.(h)Change automatic transmission
fluid and filter 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.
(i)Drain, flush, and refill cooling
system. This service can be
complex; you should have your
dealer/retailer perform this service.
See Engine Coolant on page 9-13 for
what to use. Inspect hoses. Clean
radiator, condenser, pressure cap,
and filler neck. Pressure test the
cooling system and pressure cap.(j)A fluid loss in any vehicle system
could indicate a problem. Have
the system inspected and repaired
and the fluid level checked. Add
fluid if needed.
(k)If you drive regularly under dusty
conditions, inspect the filter at
each engine oil change.
(l)If you drive regularly under dusty
conditions, the filter may require
replacement more often.
(m)Drain, flush, and refill brake
hydraulic system at a regular service
interval (IorII) every two years.
This service can be complex;
you should have your dealer/retailer
perform this service. See Brakes
