OIL LIFE
Press the information button until OIL LIFE is displayed.
The engine oil life system shows an estimate of the
oil’s remaining useful life. It will show 100% when the
system is reset after an oil change. It will alert you
to change your oil on a schedule consistent with your
driving conditions.
In addition to the engine oil life system monitoring the
oil life, additional maintenance is recommended in
the Maintenance Schedule in this manual. SeeEngine
Oil on page 5-13andPart A: Scheduled Maintenance
Services on page 6-4.
Always reset the engine oil life system after an oil
change. See “How to Reset the Engine Oil Life
System” underEngine Oil Life System on page 5-16
and “OIL–LIFE RESET” underDIC Vehicle
Personalization on page 3-40.
COOLANT
Press the information button until COOLANT is
displayed. This mode shows the temperature of the
engine coolant in either degrees Fahrenheit (°F)
or degrees Celsius (°C).
DIC Warnings and Messages
These warning messages will appear in the DIC display
if there is a problem detected in one of your vehicle’s
systems. With most messages, a warning chime
will sound when the message is displayed.
The messages will clear from the display when the
condition no longer exists. You can also acknowledge
and clear some messages from the display by pressing
and holding either the reset or information buttons.
The message will come back on the next time the
vehicle is turned off and back on if the condition still
exists. Your vehicle may have other warning messages.
AUTO (Automatic) LIGHTS OFF
This message will display if the automatic headlamp
system is disabled with the headlamp switch.
AUTO (Automatic) LIGHTS ON
This message will display if the automatic headlamp
system is enabled with the headlamp switch.

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 your engine
at extremely low temperatures.
Engine Oil Additives
Do not add anything to your oil. The recommended oils
with the starburst symbol that meet GM Standard
GM6094M are all you will need for good performance
and engine protection.
When to Change Engine Oil (Vehicles
Without a Driver Information Center)
If your vehicle does not have a Driver Information
Center (DIC), change the engine oil and lter at the
intervals speci ed in the maintenance schedule. See
Scheduled Maintenance on page 6-4.
If your vehicle has a Driver Information Center, it has
the Engine Oil Life System. SeeEngine Oil Life System
on page 5-16for information on when to change your
engine oil.
Engine Oil Life System
When to Change Engine Oil (Vehicles
With Driver Information Center)
If your vehicle has a Driver Information Center (DIC), it
has the Engine Oil Life System, 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 3-38.
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 your oil regularly and keep it at the proper level.

The following explains your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, seeEngine Overheating on
page 5-23.
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
®may
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at the rst maintenance
service after each 25,000 miles (41 500 km) or
24 months, whichever occurs rst. Any repairs
would not be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your vehicle.
What to Use
Use a mixture of one-half clean, drinkable water and
one-half DEX-COOL®coolant which will not damage
aluminum parts. If you use this coolant mixture, you do
not need to add anything else.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle’s coolant warning system is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you would not get the overheat warning.
Your engine could catch re and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.

Overheated Engine Protection
Operating Mode
This emergency operating mode allows your vehicle to
be driven to a safe place in an emergency situation. If an
overheated engine condition exists, an overheat
protection mode which alternates ring groups of
cylinders helps prevent engine damage. In this mode, you
will notice a signi cant loss in power and engine
performance. An engine coolant temperature warning
light will come on in the instrument panel to indicate that
an overheat condition exists. Driving extended miles (km)
in the overheat 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 5-13.
Cooling System
When you decide it is safe to lift the hood, here is what
you will see:
A. Electric Engine Cooling Fans
B. Coolant Surge Tank and Pressure Cap

Footnotes
†The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to
the completion of the vehicle’s useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the
maintenance be recorded.
*If your vehicle has a Driver Information Center (DIC),
it also has the GM Oil Life System, a computer system
that lets you know when to change the 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 on the
Driver Information Center (DIC) will come on. See DIC
Warnings and Messages on page 3-38.Change
your oil as soon as possible within the next two times
you stop for fuel. See Engine Oil on page 5-13.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,
your engine oil and lter must be changed at least once
a year and at this time the system must be reset. It is
also important to check your oil regularly and keep it at
the proper level.
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. See Engine Oil Life System
on page 5-16 for information on resetting the system.
+A good time to check your brakes is during tire
rotation. See Brake System Inspection on page 6-20.
