2007 PONTIAC GRAND PRIX oil change

Overheated Engine Protection
Operating Mode
The overheated engine protection operating mode
allows the vehicle to be driven to a safe place in an
emergency situation. If an overheated engine
condition exists, this protection mode alternates
ring groups of cylinders to help prevent engine
damage. In this mode, there will be a signicant
loss in power and engine performance. The engine
coolant temperature gage indicator will move to the
shaded area, and the engine coolant temperature
warning light will come on, showing that an
overheated engine condition exists. Driving
extended miles (km) and/or towing a trailer in the
overheated engine protection mode should be
avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil will be
severely degraded. Repair the cause of coolant
loss, change the oil and reset the oil life system.
SeeEngine Oil on page 350.

6. Remove all wheel nuts and take off the
at tire.
{CAUTION:
Rust or dirt on the wheel, or on the parts
to which it is fastened, can make the
wheel nuts become loose after 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 needed, to
get all the rust or dirt off.7. Remove any rust or
dirt from the wheel
bolts, mounting
surfaces and spare
wheel.
8. Install the compact spare tire.
{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.

Do not clean your vehicle using the following
cleaners or techniques:
Never use a knife or any other sharp object to
remove a soil from any interior surface.
Never use a stiff brush. It can cause damage
to your vehicle’s interior surfaces.
Never apply heavy pressure or rub
aggressively with a cleaning cloth. Use of
heavy pressure can damage your interior and
does not improve the effectiveness of soil
removal.
Use only mild, neutral-pH soaps. Avoid
laundry detergents or dishwashing soaps with
degreasers. Using too much soap will leave
a residue that leaves streaks and attracts dirt.
For liquid cleaners, about 20 drops per
gallon (3.78 L) of water is a good guide.
Do not heavily saturate your upholstery while
cleaning.
Damage to your vehicle’s interior may result
from the use of many organic solvents such
as naptha, alcohol, etc.
Fabric/Carpet
Cleaning Fabric/Carpet
Use a vacuum cleaner often to get rid of dust and
loose dirt. Wipe vinyl, leather, plastic, and
painted surfaces with a clean, damp cloth.
Your dealer has cleaners for the cleaning of fabric
and carpet. They will clean normal spots and
stains very well.
If the vehicle has the Ultra Lux
®suede fabric,
follow the listed procedures except do not use any
solvents or dry cleaning products.
Here are some cleaning tips:
Always read the instructions on the cleaner
label.
Clean up stains as soon as you can, before
they set.
Carefully scrape off any excess stain.
Use a clean cloth or sponge, and change to a
clean area often. A soft brush may be used if
stains are stubborn.
To avoid forming a ring on fabric after spot
cleaning, clean the entire area immediately
or it will set.
449

Stains caused by oil and grease can be cleaned
with an approved GM cleaner and a clean,
white cloth.
1. Carefully scrape off excess stain.
2. Clean with cool water and allow to dry
completely.
3. If a stain remains, follow the cleaner
instructions described earlier.
Leather
A soft cloth dampened with water may be used to
remove dust. If a more thorough cleaning is
necessary, a soft cloth dampened with a mild soap
solution can be used. Allow the leather to dry
naturally. Do not use heat to dry. Never use steam
to clean leather. Never use spot lifters or spot
removers on leather. Many commercial leather
cleaners and coatings that are sold to preserve
and protect leather may permanently change
the appearance and feel of your leather and are
not recommended. Do not use silicone or
wax-based products, or those containing organic
solvents to clean your vehicle’s interior becausethey can alter the appearance by increasing the
gloss in a non-uniform manner. Never use
shoe polish on your leather.
Ultra Lux Suede
Cleaning Ultra Lux Suede
Use a mild solution of lukewarm water and a
neutral dish soap on a soft cloth or sponge. For
the following stains, follow these instructions:
Coffee, Tea, and Milk:Blot with a clean,
soft, white cloth. Then clean with mild soapy
water and a clean white cloth.
Cosmetics:Clean with mild soapy water and a
clean white cloth.
Jelly, Syrup, and Fruit:Remove most of the
solids, then clean with warm tap water and a clean
white cloth.
Oil and Grease:Sprinkle baking soda on the
spot, brush, then wipe with a clean white cloth.

When the CHANGE OIL SOON message comes
on, it means that service is required for your
vehicle. SeeDIC Warnings and Messages on
page 200. Have your vehicle serviced 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 engine oil life system may not
indicate that vehicle service is necessary for over a
year. However, your engine oil and lter must be
changed at least once a year and at this time the
system must be reset. Your GM Goodwrench
®
dealer has GM-trained service technicians who will
perform this work using genuine GM parts and reset
the system.
473

If the engine oil life system is ever reset
accidentally, you must service your vehicle within
3,000 miles (5 000 km) since your last service.
Remember to reset the oil life system whenever
the oil is changed. SeeEngine Oil Life System on
page 353for information on the Engine Oil Life
System and resetting the system.
When the CHANGE OIL SOON message appears,
certain services, checks, and inspections are
required. Required services are described in the
following for “MaintenanceI” and “MaintenanceII.”
Generally, it is recommended that your rst
service be MaintenanceI, your second service be
MaintenanceII, and that you alternate
MaintenanceIand MaintenanceIIthereafter.
However, in some cases, MaintenanceIImay be
required more often.MaintenanceI— Use MaintenanceIif the
CHANGE OIL SOON message comes on within
10 months since the vehicle was purchased
or MaintenanceIIwas performed.
MaintenanceII— Use MaintenanceIIif the
previous service performed was MaintenanceI.
Always use MaintenanceIIwhenever the message
comes on 10 months or more since the last
