your driving conditions.When the remaining oil life is low, the system will
alert you with the message CHANGE ENGINE OIL.
Remember, you must reset the engine oil life
system yourself after each oil change. It will not
reset itself. To reset the system, seeEngine
Oil Life System on page 340. Be careful not to
reset the engine oil life system accidentally at any
time other than when the oil has just been
changed. It cannot be reset accurately until the
next oil change.

Care of the CD Player
Do not use CD lens cleaners for CD players
because the lens of the CD optics can become
contaminated by lubricants.
Diversity Antenna System
The AM-FM antenna is a hidden self tuning
system. It optimizes the AM and FM signals
relative to the vehicle’s position and radio station
source. No maintenance or adjustments are
needed.
XM™ Satellite Radio Antenna
System
If your vehicle has the XM™ Satellite Radio
Service, it will have an XM™ Satellite Radio
antenna. This type of antenna is located on
the roof or on the trunk lid of your vehicle.
Keep this antenna clear of snow and ice build
up for clear radio reception.
272
Vehicles with the Z51 performance package
have greaseable outer ends on both of the rear
toe-links. Under normal use, lubrication should
be performed as described in the maintenance
schedule. SeeScheduled Maintenance on
page 433andRecommended Fluids and
Lubricants on page 443. If you use the vehicle
for racing, lubrication should be performed at the
end of each racing day. See your dealer/retailer
for lubrication and make sure any needed
repairs are made at once. Proper procedures for
performing these services can be found in the
service manual. SeeService Publications
Ordering Information on page 468.Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to
be impaired — by alcohol or drugs, with night
vision problems, or by fatigue.
Here are some tips on night driving.
Drive defensively.
Do not drink and drive.
Adjust the inside rearview mirror to reduce
the glare from headlamps behind you.
Since you cannot see as well, slow down
and keep more space between you and
other vehicles.
Slow down, especially on higher speed roads.
Your vehicle’s headlamps can light up only so
much road ahead.
In remote areas, watch for animals.
If you are tired, pull off the road in a safe
place and rest.

California Proposition 65 Warning
Most motor vehicles, including this one, contain
and/or emit chemicals known to the State of
California to cause cancer and birth defects
or other reproductive harm. Engine exhaust,
many parts and systems (including some
inside the vehicle), many uids, and some
component wear by-products contain and/or
emit these chemicals.
Doing Your Own Service Work
{CAUTION:
You can be injured and your vehicle
could be damaged if you try to do
service work on a vehicle without
knowing enough about it.
Be sure you have sufficient
knowledge, experience, the proper
replacement parts, and tools
before you attempt any vehicle
maintenance task.
Be sure to use the proper nuts, bolts,
and other fasteners. English and
metric fasteners can be easily
confused. If you use the wrong
fasteners, parts can later break or
fall off. You could be hurt.
320
If you want to do some of your own service
work, you should use the proper service manual.
It tells you much more about how to service
your vehicle than this manual can. To order the
proper service manual, seeService Publications
Ordering Information on page 468.
Your vehicle has an airbag system. Before
attempting to do your own service work,
seeServicing Your Airbag-Equipped Vehicle
on page 64.
You should keep a record with all parts receipts
and list the mileage and the date of any service
work you perform. SeeMaintenance Record
on page 447.
Adding Equipment to the Outside
of Your Vehicle
Things you might add to the outside of your
vehicle can affect the air ow around it. This may
cause wind noise and affect windshield washer
performance. Check with your dealer before
adding equipment to the outside of your vehicle.
Fuel
Use of the recommended fuel is an important
part of the proper maintenance of your vehicle.
To help keep the engine clean and maintain
optimum vehicle performance, GM recommends
the use of gasoline advertised as TOP TIER
Detergent Gasoline.
The 8th digit of the Vehicle Identi cation
Number (VIN) shows the code letter or number
that identi es your vehicle’s engine. The VIN is at
the top left of the instrument panel. SeeVehicle
Identi cation Number (VIN) on page 418.
Gasoline Octane
If your vehicle has the 6.0L V8 engine (VIN Code U),
use premium unleaded gasoline with a posted
octane rating of 91 or higher. You may also use
regular unleaded gasoline rated at 87 octane or
higher, but your vehicle’s acceleration may be
slightly reduced, and you may notice a slight
audible knocking noise, commonly referred to as
spark knock. If the octane is less than 87, you may
notice a heavy knocking noise when you drive.
