2007 PONTIAC GRAND PRIX oil change

2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F
or−18°C), it could be ooded with too much
gasoline. Try pushing the accelerator
pedal all the way to the oor and holding it
there as you hold the key in START for up to
a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the
cranking motor to cool down. When the engine
starts, let go of the key and accelerator. If
the vehicle starts briey but then stops again,
do the same thing. This clears the extra
gasoline from the engine. Do not race the
engine immediately after starting it. Operate
the engine and transaxle gently until the
oil warms up and lubricates all moving parts.
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 do not, your engine might
not perform properly. Any resulting damage
would not be covered by your vehicle’s
warranty.Engine Coolant Heater
The vehicle may be equipped with an engine
coolant heater. In very cold weather, 0°F (−18°C)
or colder, the engine coolant heater can help.
The vehicle will start easier and get better
fuel economy during engine warm-up. Usually, the
coolant heater should be plugged in a minimum
of four hours prior to starting the vehicle. At
temperatures above 32°F (0°C), use of the coolant
heater is not required. Your vehicle may also
have an internal thermostat in the plug end of the
cord. This will prevent operation of the engine
coolant heater when the temperature is at or above
0°F (−18°C) as noted on the cord.

the need to manually set the compass. However,
under certain circumstances, such as during a long
distance cross-country trip, it will be necessary
to compensate for compass variance and reset the
zone through the DIC. SeeDIC Compass
(Uplevel DIC) on page 198for more information.
The buttons on the DIC trip computer are gages,
trip odometer, set/reset, options, and fuel.

CHANGE OIL SOON
This symbol comes on
with this message.
This message displays when service is required
for the vehicle. See your dealer. SeeEngine Oil on
page 350andScheduled Maintenance on
page 473for more information.
The CHANGE OIL SOON message is reset by
acknowledging the message. The ENGINE OIL
MONITOR SYSTEM screen under the options
menu on the DIC must also be reset. See “Engine
Oil Monitor System” in options underDIC Controls
and Displays (Base Level DIC) on page 186orDIC

for three seconds if the message has been
acknowledged, but the condition still exists when
the engine is turned off.
If the condition still exists, the message re-appears
when the engine is turned on.
CHARGING SYSTEM FAILURE
This symbol comes on
with this message.
This message displays when there is a problem
with the generator and battery charging systems.
Driving with this problem could drain the battery.
Turn off all unnecessary accessories. Stop
and turn off the vehicle as soon as it is safe to do

If you are in an area of extreme cold, where the
temperature falls below−20°F (−29°C), it is
recommended that you use either an SAE 5W-30
synthetic oil or an SAE 0W-30 oil. Both will
provide easier cold starting and better protection
for the engine at extremely low temperatures.
Engine Oil Additives
Do not add anything to the engine oil. The
recommended oils with the starburst symbol that
meet GM Standard GM6094M are all you will need
for good performance and engine protection.
Engine Oil Life System
When to Change Engine Oil
Your vehicle has a computer system that lets you
know when to change the engine oil and lter.
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. A CHANGE OIL SOON message
will come on. SeeDIC Warnings and Messages on
page 200. Change the oil as soon as possible
within the next 600 miles (1 000 km). 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, the
engine oil and lter must be changed at least
once a year and at this time the system must be
reset. Your dealer has GM-trained service
people who will perform this work using genuine
GM parts and reset the system. It is also important
to check the oil regularly and keep it at the
proper level.
If the system is ever reset accidentally, you must
change the oil at 3,000 miles (5 000 km) since
the 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 the engine oil and lter based on vehicle
use. Anytime the oil is changed, reset the system
so it can calculate when the next oil change is
required. If a situation occurs where you change the
oil prior to a CHANGE OIL SOON message
appearing on the DIC, reset the system.
To reset the oil life system, after the oil has been
changed, use the following procedure:
1. Press the options button on the DIC until
ENGINE OIL MONITOR appears on the
DIC screen.
2. Press the set/reset button to reset the system.
The next screen indicates that the engine oil
monitor system has been reset.
If the vehicle is equipped with the trip computer
DIC, when the gage button is pressed and
the OIL LIFE REMAINING mode appears, it
should read 100 percent OIL LIFE
REMAINING.
3. Turn the key to OFF.If the CHANGE OIL SOON 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
used oil, ask your dealer, a service station, or a
local recycling center for help.

Supercharger Oil
Because they are technically qualied and have
the proper tools, you should have your dealer
perform this maintenance.
When to Check
SeeAdditional Required Services on page 476for
when the oil level should be checked.
What Kind of Oil to Use
Use only the recommended supercharger oil. See
Recommended Fluids and Lubricants on
page 483.
Engine Air Cleaner/Filter
The engine air cleaner/lter is located in the
engine compartment on the driver’s side of the
vehicle. SeeEngine Compartment Overview
on page 346for more information on location.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/lter at the MaintenanceII
intervals and replace it at the rst oil change
after each 50,000 mile (83 000 km) interval. See
Scheduled Maintenance on page 473for more
information. If you are driving in dusty/dirty
conditions, inspect the lter at each engine oil
change.

5. To reinstall the cover, position the tabs
through the slots on the housing. If your
vehicle has one of the 3800 V6 engines, a
notch on the sides of the lter cover will
indicate the correct engagement.
6. Push the cover tabs on top of the housing to
lock the cover in place.
{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 ames 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.
Automatic Transaxle Fluid
When to Check and Change Automatic
Transaxle Fluid
A good time to check the automatic transaxle uid
level is when the engine oil is changed.
Change the uid and lter at the intervals listed in
Additional Required Services on page 476, and
be sure to use the transaxle uid listed in
Recommended Fluids and Lubricants on page 483.
