page 433. After an oil change, the engine oil
life system must be reset. See “Engine Oil Life”
underDIC Controls and Displays on page 208.
Also, seeEngine Oil on page 333andEngine Oil
Life System on page 340for more information.
CHECK BRAKE FLUID
This message displays, a chime sounds, and the
brake system warning light on the instrument
panel cluster turns on if the ignition is on to inform
the driver that the brake uid level is low. See
Brake System Warning Light on page 196. Have
the brake system serviced by your dealer as
soon as possible. SeeBrakes on page 361.

If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you
want the vehicle to go. If you start steering quickly
enough, your vehicle may straighten out. Always
be ready for a second skid if it occurs.
Of course, traction is reduced when water, snow,
ice, gravel, or other material is on the road.
For safety, you will want to slow down and adjust
your driving to these conditions. It is important
to slow down on slippery surfaces because
stopping distance will be longer and vehicle
control more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration,
or braking, including reducing vehicle speed by
shifting to a lower gear. Any sudden changes could
cause the tires to slide. You may not realize the
surface is slippery until your vehicle is skidding.
Learn to recognize warning clues — such as
enough water, ice, or packed snow on the road
to make a mirrored surface — and slow down
when you have any doubt.
Remember: Any Anti-Lock Brake System (ABS)
helps avoid only the braking skid.Racing or Other Competitive Driving
See your warranty book before using your
vehicle for racing or other competitive driving.
Notice:If you use your vehicle for racing or
other competitive driving, the engine may
use more oil than it would with normal
use. Low oil levels can damage the engine.
For information on how to add oil, see
Engine Oil on page 333.
Z06 Only: Be sure to check the oil level often
during racing or other competitive driving
and keep the level at or near the upper mark
that shows the proper operating range on
the engine oil dipstick.
Except Z06: Be sure to check the oil level
often during racing or other competitive driving
and keep the level at or near 1 quart (1 L)
above the upper mark that shows the proper
operating range on the engine oil dipstick.
After the competitive driving, remove excess
oil so that the level on the dipstick is not
above the upper mark that shows the proper
operating range.

Your vehicle’s engine is lled at the factory
with a Mobil 1®synthetic oil, which meets all
requirements for your vehicle.
Substitute Engine Oil: When adding oil to
maintain engine oil level, oil meeting GM
Standard GM4718M may not be available.
You can add substitute oil designated SAE 5W-30
with the starburst symbol at all temperatures.
Substitute oil not meeting GM Standard GM4718M
should not be used for an oil change.
Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet GM
Standard GM4718M are all you need for good
performance and engine protection.
Engine Oil Life System
When to Change Engine Oil
Your vehicle has a computer that lets you know
when to change your 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.
Z06 models are equipped with a racetrack-ready
dry sump engine lubrication system. This
high-performance system operates differently
than a standard engine lubrication system
and requires a special procedure when changing
the engine oil and lter. SeeEngine Oil
on page 333.
340

When the system has calculated that oil life has
been diminished, it will indicate that an oil change
is necessary. A CHANGE ENGINE OIL message
will come on. Change your 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, your 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.
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.How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to
change your engine oil and lter based on vehicle
use. Anytime your oil is changed, reset the
system so it can calculate when the next oil
change is required. If a situation occurs where
you change your oil prior to a CHANGE ENGINE
OIL message being turned on, reset the system.
To reset the CHANGE ENGINE OIL message
after an oil change, do the following:
1. Press the TRIP button so the OIL LIFE
percentage is displayed.
2. Press RESET and hold for two seconds.
OIL LIFE REMAINING 100% will appear.
If the CHANGE ENGINE OIL 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
your used oil, ask your dealer, a service station,
or a local recycling center for help.
Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 330
for the location of the engine air cleaner/lters.Notice:If you spray water into the engine
air cleaner/lter intake and water enters
the engine air cleaner/lter housing, you
could damage your vehicle’s engine.
The repairs would not be covered by your
warranty. Do not spray water into the engine
air cleaner/lter intake and/or housing.
If you are cleaning your vehicle with the hood
open, take care not to spray water directly
into either end of the air cleaner/lter housing,
as shown in the illustration, as this could damage
your vehicle’s engine.

When to Inspect the Engine
Air Cleaner/Filters
Inspect the air cleaner/lters at the MaintenanceII
intervals and replace them at the rst oil change
after each 50,000 mile (83 000 km) interval.
SeeScheduled Maintenance on page 433for
more information. If you are driving in dusty/dirty
conditions, inspect the lters at each engine
oil change.
How to Inspect the Engine
Air Cleaner/Filters (6.0L V8 Engine)
To inspect the air cleaner/lters, remove the lters
from the vehicle and lightly shake the lters to
release loose dust and dirt. If the lters remain
caked with dirt, new lters are required.
To inspect or replace the engine air cleaner/lters,
do the following:1. Pull the latches on each side of the cover to
open, then move the latches up and out of
the way.
2. Push the air cleaner/lter cover toward the front
of the vehicle and then pull it up and away.
3. Inspect or replace the lter. SeeNormal
Maintenance Replacement Parts on page 445.
4. Reverse Steps 1 and 2 to replace the
air cleaner/lter cover.
5. Repeat the procedure for the second
air cleaner/lter.
343

If you no longer have the overheat warning,
you can drive. Just to be safe, drive slower for
about 10 minutes. If the warning does not
come back on, you can drive normally.
If the warning continues and you are not
stopped, pull over, stop, and park your vehicle
right away.
If there is still no sign of steam, you can idle the
engine for three minutes while you are parked.
If you still have the warning, turn off the engine
and get everyone out of the vehicle until it
cools down. Also, see “Overheated Engine
Protection Operating Mode” later in this section.
You may decide not to lift the hood but to get
service help right away.Overheated Engine Protection
Operating Mode
If an overheated engine condition exists and the
messages COOLANT OVER TEMPERATURE
and REDUCED ENGINE POWER are displayed,
along with the Check Engine light, an overheat
protection mode which alternates ring groups of
cylinders helps prevent engine damage. In
this mode, you will notice a loss in power and
engine performance. This operating mode allows
your vehicle to be driven to a safe place in an
emergency; you may drive up to 50 miles (80 km).
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 333.
