Radio Data System (RDS)
The audio system has a Radio Data System (RDS).
RDS features are available for use only on FM stations
that broadcast RDS information.
With RDS, the radio can do the following:
Seek to stations broadcasting the selected type of
programming.
Receive announcements concerning local and
national emergencies.
Display messages from radio stations.
Seek to stations with traffic announcements.
This system relies upon receiving specic information
from these stations and works only when the information
is available. In rare cases, a radio station can broadcast
incorrect information that causes the radio features
to work improperly. If this happens, contact the radio
station.
While the radio is tuned to an RDS station, the station
name or call letters display. RDS stations can also
provide the time of day, a program type (PTY) for current
programming, and the name of the program being
broadcast.
Playing the Radio
Top Knob (Power/Volume):Press to turn the system
on and off. Turn clockwise or counterclockwise to
increase or decrease the volume.

display while using RDS. The display options are station
name, RDS station frequency, PTY, and the name of
the program (if available).
For XM™ (if equipped), press while in XM™ mode to
retrieve four different categories of information related to
the current song or channel: Artist, Song Title,
Category or PTY, Channel Number/Channel Name.
To change the default on the display, press until you
see the desired display, then hold for two seconds.
The radio produces one beep and the selected display
is now the default.
AUTO
n(Automatic Volume):Automatic volume
automatically adjusts the audio system to make up
for road and wind noise as you drive, by increasing the
volume as vehicle speed increases.
Set the volume at the desired level. Press this button
to select AUTO VOLUME MIN (minimum), AUTO
VOLUME MED (medium), or AUTO VOLUME MAX
(maximum). Each higher setting provides more volume
compensation at faster vehicle speeds. To turn
automatic volume off, press this until AUTO VOLUME
OFF displays.

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 (ABS) Warning
Light on page 3-42.
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.
Using ABS
Do not pump the brakes. Just hold the brake pedal
down rmly and let antilock work for you. You might hear
a motor or clicking noise and feel the brake pedal
move a little during a stop, but this is normal.
Braking in Emergencies
With ABS, you can steer and brake at the same time.
In many emergencies, steering can help you more than
even the very best braking.

Selective Ride Control
You may have a ride control system on your vehicle
called Magnetic Selective Ride Control. The system
provides the following performance benets:
Reduced Impact Harshness
Improved Road Isolation
Improved High-Speed Stability
Improved Handling Response
Better Control of Body Ride Motions
This knob is located on the
center console. Turn it to
select the suspension
of your choice.TOUR:Use for normal city and highway driving.
This setting provides a smooth, soft ride.
SPORT:Use where road conditions or personal
preference demand more control. This setting provides
more “feel”, or response to the road conditions.
You can select a setting at any time. Based on road
conditions, steering wheel angle and your vehicle speed,
the system automatically adjusts to provide the best
ride and handling. Select a new setting whenever driving
conditions change.

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 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.Z06 models have 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 5-17.
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
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 your
last oil change. Remember to reset the oil life system
whenever the oil is changed.
5-23

Brake Wear
Your vehicle has disc brakes. Disc brake pads have
built-in wear indicators that make a high-pitched warning
sound when the brake pads are worn and new pads
are needed. The sound can come and go or be heard all
the time your vehicle is moving, except when you are
pushing on the brake pedal rmly.
{CAUTION:
The brake wear warning sound means that soon
the brakes will not work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
Notice:Continuing to drive with worn-out brake
pads could result in costly brake repair.
Some driving conditions or climates can cause a brake
squeal when the brakes are rst applied or lightly applied.
This does not mean something is wrong with the brakes.
Brake linings should always be replaced as complete
axle sets.
Brake Pedal Travel
See your dealer/retailer if the brake pedal does not
return to normal height, or if there is a rapid increase in
pedal travel. This could be a sign that brake service
might be required.
Brake Adjustment
As you make brake stops, the disc brakes automatically
adjust for wear.
Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. Your vehicle
was designed and tested with top-quality brake parts.
When you replace parts of the braking system — for
example, when the brake linings wear down and you
need new ones put in — be sure you get new approved
replacement parts. If you do not, the brakes might not
work properly. For example, if someone puts in brake
linings that are wrong for your vehicle, the balance
between the front and rear brakes can change — for the
worse. The braking performance you have come to
expect can change in many other ways if someone puts
in the wrong replacement brake parts.

The TPMS operates on a radio frequency and complies
with RSS-210 of Industry and Science Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.
Tire Pressure Monitor Operation
The Tire Pressure Monitor System (TPMS) is designed
to warn the driver when a low tire pressure condition
exists. TPMS sensors are mounted onto each tire
and wheel assembly on your vehicle. The TPMS
sensors monitor the air pressure in the vehicle’s tires
and transmits the tire pressure readings to a receiver
located in the vehicle.When a low tire pressure
condition is detected, the
TPMS illuminates the
low tire pressure warning
light, located in the
instrument panel cluster.
At the same time a message to check the pressure in a
specic tire appears on the Driver Information Center
(DIC) display. The low tire pressure warning light
and the DIC warning message appear at each ignition
cycle until the tires are inated to the correct ination
pressure. Using the DIC, tire pressure levels can
be viewed by the driver. For additional information and
details about the DIC operation and displays see
DIC Operation and Displays on page 3-52andDIC
Warnings and Messages on page 3-57.
The low tire pressure warning light may come on in cool
weather when the vehicle is rst started, and then
turn off as you start to drive. This could be an early
indicator that the air pressure in the tire(s) are getting
low and need to be inated to the proper pressure.
