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
This system relies upon receiving specific
information from these stations and only works
when the information is available. In rare cases, a
radio station may 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 appear on the display
instead of the frequency. RDS stations may
also provide the time of day, a program type (PTY)
for current programming, and the name of the
program being broadcast.

Section 4 Driving Your Vehicle
227

Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic.
This is a mistake. The brakes may not have time to
cool between hard stops. The brakes will wear out
much faster if you do a lot of heavy braking. If you
keep pace with the traffic and allow realistic
following distances, you will eliminate a lot of
unnecessary braking. That means better braking
and longer brake life.
If your vehicle’s engine ever stops while you are
driving, brake normally but do not pump the
brakes. If you do, the pedal may get harder to
push down. If the engine stops, you will still have
some power brake assist. But you will use it
when you brake. Once the power assist is used
up, it may take longer to stop and the brake pedal
will be harder to push.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 290.Anti-Lock Brake System (ABS)
Your vehicle has the Anti-Lock 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. This is normal.
If there is a problem
with the ABS, this
warning light will stay
on. SeeAnti-Lock Brake
System Warning Light
on page 176.
233

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 firmly and let anti-lock work for you.
You might feel the brakes vibrate or notice
some noise, 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.
Locking Rear Axle
If your vehicle has this feature, your locking rear
axle can give you additional traction on snow, mud,
ice, sand or gravel. It works like a standard axle
most of the time, but when one of the rear wheels
has no traction and the other does, this feature will
allow the wheel with traction to move the vehicle.
StabiliTrak®System
If your vehicle has StabiliTrak®, it combines
anti-lock brake, traction and stability control
systems and helps the driver maintain directional
control of the vehicle in most driving conditions.
When you first start your vehicle and begin to drive
away, the system performs several diagnostic
checks to ensure that it is working properly. You
may hear or feel the system working. This is normal
and does not mean there is a problem with your
vehicle. The system should initialize before the
vehicle reaches 20 mph (32 km/h). In some cases,
it may take approximately 2 miles (3.2 km) of driving
before the system initializes.
