Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this inspection
could prevent you from getting a vehicle registration.
Here are some things you need to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection if the check
engine light is on or not working properly.
Your vehicle will not pass this inspection if the
OBD (on-board diagnostic) system determines that
critical emission control systems have not been
completely diagnosed by the system. The vehicle
would be considered not ready for inspection.
This can happen if you have recently replaced the
battery or if the battery has run down. The diagnostic
system is designed to evaluate critical emission
control systems during normal driving. This can take
several days of routine driving. If you have done this
and your vehicle still does not pass the inspection for
lack of OBD system readiness, your dealer/retailer
can prepare the vehicle for inspection.
Oil Pressure Light
{CAUTION:
Do not keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be covered
by your warranty. Always follow the maintenance
schedule in this manual for changing engine oil.
This light will come on
briey when you start
your engine. If it does
not, have your vehicle
serviced.
When the light comes on and stays on, it means
that oil is not owing through your engine properly.
You could be low on oil and you might have some
other system problem.

When the remaining oil life is low, the CHANGE
ENGINE OIL SOON message will appear on the
display along with the Change Engine Oil Light on the
instrument panel cluster. See “CHANGE ENGINE
OIL SOON” underDIC Warnings and Messages on
page 3-49andChange Engine Oil Light on page 3-38.
You should change the oil as soon as possible. See
Engine Oil on page 5-15. In addition to the engine oil life
system monitoring the oil life, additional maintenance
is recommended in the Maintenance Schedule in
this manual. SeeScheduled Maintenance on page 6-4
for more information.
Remember, you must reset the OIL LIFE yourself
after each oil change. It will not reset itself. Also, be
careful not to reset the OIL LIFE accidentally at any
time other than when the oil has just been changed.
It cannot be reset accurately until the next oil change.
To reset the engine oil life system, seeEngine Oil
Life System on page 5-18.

CHECK TIRE PRESSURE
This message displays when the pressure in one or
more of the vehicle’s tires needs to be checked.
This message also displays LEFT FRONT, RIGHT
FRNT (Front), LEFT REAR, or RIGHT REAR to
indicate which tire needs to be checked. You can
receive more than one tire pressure message at
a time. To read the other messages that may have
been sent at the same time, press the set/reset button.
If a tire pressure message appears on the DIC, stop
as soon as you can. Have the tire pressures checked
and set to those shown on the Tire Loading Information
label. SeeTires on page 5-52,Loading Your Vehicle
on page 4-22, andInflation - Tire Pressure on
page 5-59. The DIC also shows the tire pressure
values. SeeDIC Operation and Displays on page 3-43.
If the tire pressure is low, the low tire pressure
warning light comes on. SeeTire Pressure Light
on page 3-34.
DRIVER DOOR OPEN
This message displays when the driver door is
not closed properly. Close the door completely.
ENGINE HOT A/C
(Air Conditioning) OFF
This message displays when the engine coolant
becomes hotter than the normal operating temperature.
To avoid added strain on a hot engine, the air
conditioning compressor is automatically turned off.
When the coolant temperature returns to normal,
the A/C operation automatically resumes. You can
continue to drive your vehicle.
ENGINE OVERHEATD (Overheated)
IDLE ENGINE
Notice:If you drive your vehicle while the engine
is overheating, severe engine damage may occur.
If an overheat warning appears on the instrument
panel cluster and/or DIC, stop the vehicle as soon
as possible. Do not increase the engine speed
above normal idling speed. SeeEngine Overheating
on page 5-24for more information.
This message displays when the engine coolant
temperature is too hot. Stop and allow the vehicle
to idle until it cools down.
3-51

Antilock Brake System (ABS)
Your vehicle has the Antilock Brake System (ABS), an
advanced electronic braking system that will help
prevent a braking skid.
When you start the engine and begin to drive away,
ABS will check itself. You might hear a momentary
motor or clicking noise while this test is going on, and
you might even notice that the brake pedal moves
a little. This is normal.
If there is a problem with
ABS, this warning light will
stay on. SeeAntilock
Brake System Warning
Light on page 3-32.Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down.
If one of the wheels is about to stop rolling, the computer
will separately work the brakes at each wheel.
ABS can change the brake pressure faster than any
driver could. The computer is programmed to make the
most of available tire and road conditions. This can help
you steer around the obstacle while braking hard.
As you brake, the computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
Remember: ABS does not change the time you need
to get your foot up to the brake pedal or always
decrease stopping distance. If you get too close to the
vehicle in front of you, you will not have time to apply
the brakes if that vehicle suddenly slows or stops. Always
leave enough room up ahead to stop, even though you
have ABS.

Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet
GM Standard GM6094M are all you 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 engine oil light and a CHANGE
ENGINE OIL SOON message will come on. 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 might 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/retailer has trained service people who will
perform this work using genuine 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. Whenever
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 engine oil light
or CHANGE ENGINE OIL SOON message being turned
on, reset the system.
1. Turn the ignition key to ON/RUN with the
engine off.
2. Fully press and release the accelerator pedal three
times within ve seconds.
The change engine oil light will ash while the
system is resetting.
3. When the light stops ashing, turn the key to
LOCK/OFF.
5-18

Scheduled Maintenance
When the change engine oil light and/or CHANGE
ENGINE OIL SOON message comes on, it means that
service is required for your vehicle. 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, the engine oil and lter must be changed at
least once a year and at this time the system must be
reset. Your dealer/retailer has trained service technicians
who will perform this work using genuine parts and reset
the system.
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. See
Engine Oil Life System on page 5-18for information on
the Engine Oil Life System and resetting the system.When the change engine oil light and/or CHANGE
ENGINE 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
light/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 light/message comes on
10 months or more since the last service or if the
light/message has not come on at all for one year.

Maintenance Footnotes
(a)Visually inspect brake lines and hoses for proper
hook-up, binding, leaks, cracks, chafing, etc. Inspect
disc brake pads for wear and rotors for surface
condition. Inspect other brake parts, including calipers,
parking brake, etc. Check parking brake adjustment.
(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing parts or
signs of wear. Visually check constant velocity joints,
rubber boots, and axle seals for leaks. With 3.4L
V6 engine: Inspect electric power steering cables for
proper hook-up, binding, cracks, chafing, etc. With 3.6L
V6 engine: Inspect hydraulic power steering lines and
hoses for proper hook-up, binding, leaks, cracks,
chafing, etc.
(c)Visually inspect hoses and have them replaced if
they are cracked, swollen, or deteriorated. Inspect
all pipes, fittings and clamps; replace with genuine parts
as needed. To help ensure proper operation, a pressure
test of the cooling system and pressure cap and cleaning
the outside of the radiator and air conditioning condenser
is recommended at least once a year.(d)Inspect wiper blades for wear, cracking, or
contamination. Clean the windshield and wiper blades, if
contaminated. Replace wiper blades that are worn or
damaged. See Windshield Wiper Blade Replacement on
page 5-50andWindshield and Wiper Blades on
page 5-95for more information.
(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 Checking the
Restraint Systems on page 1-72.
(f)Lubricate all key lock cylinders, hood latch
assemblies, secondary latches, pivots, spring anchor
and release pawl, hood and door hinges, rear folding
seats, and liftgate hinges. 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)If you drive regularly under dusty conditions, the
filter may require replacement more often.
