Trip Computer
Oil Life Indicator
This feature lets you know when to change the engine
oil. It is based on the engine oil temperatures and
your driving patterns.
To see the display, press the information button
several times until OIL LIFE appears. If you see 99%
OIL LIFE, 99 percent of your current oil life remains.
The DIC may display a CHANGE OIL NOW message.
If you see CHANGE OIL NOW, it means the oil life
is gone. For more information, seeScheduled
Maintenance on page 7-4andEngine Oil on page 6-15.
When the oil is changed, you will need to reset the
system. SeeEngine Oil Life System on page 6-18.
Always keep a written record of the mileage and date
when you changed your oil.
Audio System(s)
Determine which radio your vehicle has and then read the
pages following to familiarize yourself with its features.
Driving without distraction is a necessity for a safer
driving experience. SeeDefensive Driving on page 5-2.
By taking a few moments to read this manual and get
familiar with your vehicle’s audio system, you can use it
with less effort, as well as take advantage of its features.
While your vehicle is parked, set up your audio system by
presetting your favorite radio stations, setting the tone
and adjusting the speakers. Then, when driving
conditions permit, you can tune to your favorite stations
using the presets and steering wheel controls if the
vehicle has them.
{CAUTION:
This system provides you with a far greater
access to audio stations and song listings.
Giving extended attention to entertainment
tasks while driving can cause a crash and you
or others can be injured or killed. Always keep
your eyes on the road and your mind on the
drive — avoid engaging in extended searching
while driving.

Care of Your CDs
Handle CDs carefully. Store them in their original cases
or other protective cases and away from direct
sunlight and dust. The CD player scans the bottom
surface of the disc. If the surface of a CD is damaged,
such as cracked, broken, or scratched, the CD will
not play properly or not at all. If the surface of a CD is
soiled, take a soft, lint free cloth or dampen a clean,
soft cloth in a mild, neutral detergent solution mixed
with water, and clean it. Make sure the wiping process
starts from the center to the edge.
Do not touch the bottom side of a CD while handling
it; this could damage the surface. Pick up CDs by
grasping the outer edges or the edge of the hole
and the outer edge.
Care of the CD Player
The use of CD lens cleaners for CD players is not
advised, due to the risk of contaminating the internal
lens of the CD optics with lubricants.
Diversity Antenna System
The AM-FM antennas are located under the decklid
surface in the trunk compartment. the antennas
are hidden from view and are not accessible.
If adding an aftermarket cellular telephone to your
vehicle, do not attach the antenna to the rear glass.
This would interfere with the convertible top retraction
operation and could cause damage to the
nished/painted surfaces.
XM™ Satellite Radio Antenna
System (Trunk Mounted)
Your vehicle may have the XM™ Satellite Radio
antenna that is located on the trunk of your vehicle.
Keep this antenna clear of snow and ice build up
for clear radio reception.
XM™ Satellite Radio Antenna
System (Diversity System)
Your vehicle may have the XM™ Satellite Radio
antennas that are located in the outside rear view
mirrors. These antennas are hidden from view and
are not accessible.

Remember: Any traction control system helps avoid only
the acceleration skid. If your traction control system is
off, then an acceleration skid is also best handled
by easing your foot off the accelerator pedal.
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 (XLR-V)
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. Be sure to check the
oil level often during racing or other competitive
driving and keep the level at or near 2 quarts (2 L)
above the upper mark that shows the proper
operating range on the engine oil dipstick.
For information on how to add oil, seeEngine Oil
on page 6-15. 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.

Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir full?
Are all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you checked
all levels?
Lamps:Are they all working? Are the lenses clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inated
to the recommended pressure?
Weather Forecasts:What is the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
Maps:Do you have up-to-date maps?
Highway Hypnosis
Is there actually such a condition as highway hypnosis?
Or is it just plain falling asleep at the wheel? Call it
highway hypnosis, lack of awareness, or whatever.
There is something about an easy stretch of road with
the same scenery, along with the hum of the tires on
the road, the drone of the engine, and the rush of
the wind against the vehicle that can make you sleepy.
Do not let it happen to you! If it does, your vehicle
can leave the road in less than a second, and you
could crash and be injured.
What can you do about highway hypnosis? First, be
aware that it can happen.
Then here are some tips:
Make sure your vehicle is well ventilated, with a
comfortably cool interior.
Keep your eyes moving. Scan the road ahead and
to the sides. Check your rearview mirrors and your
instruments frequently.
If you get sleepy, pull off the road into a rest,
service, or parking area and take a nap, get some
exercise, or both. For safety, treat drowsiness
on the highway as an emergency.

Additives
To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent engine and fuel system deposits from forming,
allowing your emission control system to work properly. In
most cases, you should not have to add anything to your
fuel. However, some gasolines contain only the minimum
amount of additive required to meet U.S. Environmental
Protection Agency regulations. To help keep fuel injectors
and intake valves clean, or if your vehicle experiences
problems due to dirty injectors or valves, look for gasoline
that is advertised as TOP TIER Detergent Gasoline. Also,
your GM dealer has additives that will help correct and
prevent most deposit-related problems.
Gasolines containing oxygenates, such as ethers and
ethanol, and reformulated gasolines may be available in
your area. General Motors recommends that you use
these gasolines if they comply with the specications
described earlier. However, E85 (85% ethanol) and other
fuels containing more than 10% ethanol must not be used
in vehicles that were not designed for those fuels.
Notice:Your vehicle was not designed for fuel that
contains methanol. Do not use fuel containing
methanol. It can corrode metal parts in your fuel
system and also damage the plastic and rubber
parts. That damage would not be covered under
your warranty.Some gasolines that are not reformulated for low
emissions may contain an octane-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask the attendant where you buy gasoline
whether the fuel contains MMT. General Motors
recommends against the use of such gasolines.
Fuels containing MMT can reduce the life of spark plugs
and the performance of the emission control system
may be affected. The malfunction indicator lamp may turn
on. If this occurs, return to your authorized GM dealer
for service.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard
to nd. Never use leaded gasoline or any other fuel
not recommended in the previous text on fuel. Costly
repairs caused by use of improper fuel would not
be covered by your warranty.
To check the fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you will be driving.

Filling a Portable Fuel Container
{CAUTION:
Never ll a portable fuel container while it is in
your vehicle. Static electricity discharge from
the container can ignite the gasoline vapor.
You can be badly burned and your vehicle
damaged if this occurs. To help avoid injury
to you and others:
Dispense gasoline only into approved
containers.
Do not ll a container while it is inside a
vehicle, in a vehicle’s trunk, pickup bed,
or on any surface other than the ground.
Bring the ll nozzle in contact with the
inside of the ll opening before operating
the nozzle. Contact should be maintained
until the lling is complete.
Do not smoke while pumping gasoline.
Checking Things Under
the Hood
{CAUTION:
An electric fan under the hood can start up
and injure you even when the engine is not
running. Keep hands, clothing, and tools away
from any underhood electric fan.
{CAUTION:
Things that burn can get on hot engine parts
and start a re. These include liquids like fuel,
oil, coolant, brake uid, windshield washer
and other uids, and plastic or rubber. You or
others could be burned. Be careful not to drop
or spill things that will burn onto a hot engine.
