CLEAN RADAR
When this message displays, it means that the Adaptive
Cruise Control (ACC) system and the Forward Collision
Alert (FCA) system are disabled because the radar
is blocked and cannot detect vehicles in your path.
It may also activate during heavy rain or due to road
spray. To clean the system, see “Cleaning the System”
underAdaptive Cruise Control on page 3-19.
CRUISE SET TO XXX MPH (km/h)
This message will display whenever the cruise control
is set. SeeCruise Control on page 3-16andAdaptive

normal idling speed. SeeEngine Overheating
on page 5-25for more information.
This message will display when the engine has
overheated. Immediately look for a safe place to pull
your vehicle over and turn the engine off right away to
avoid severe engine damage. SeeEngine Overheating
on page 5-25andOverheated Engine Protection
Operating Mode on page 5-27. A chime will also sound
when this message is displayed.
ENGINE POWER REDUCED
This message will display when the engine power is
being reduced to protect the engine from damage. There
could be several malfunctions that might cause this
message. Reduced engine power can affect the vehicle’s
ability to accelerate. If this message is on, but there is no
reduction in performance, proceed to your destination.
The performance may be reduced the next time the
vehicle is driven. The vehicle may be driven at a reduced
speed while this message is on, but acceleration and
speed may be reduced. Anytime this message stays on,
the vehicle should be taken to your GM dealer for service
as soon as possible.
3-79

vehicle as soon as possible. Do not drive the vehicle
until the cause of the low oil pressure is corrected.
SeeEngine Oil on page 5-13for more information.
A multiple chime will sound when this message is
displayed. SeeEngine Oil on page 5-13for more
information.

Here are some ways in which you can help avoid
distraction while driving.
While your vehicle is parked:
Familiarize yourself with all of its controls.
Familiarize yourself with its operation.
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
radio stations using the presets and steering wheel
controls if the vehicle has them.
Notice:Before adding any sound equipment to
your vehicle, such as an audio system, CD player,
CB radio, mobile telephone, or two-way radio, make
sure that it can be added by checking with your
dealer. Also, check federal rules covering mobile
radio and telephone units. If sound equipment can
be added, it is very important to do it properly.
Added sound equipment may interfere with
the operation of your vehicle’s engine, radio, or
other systems, and even damage them. Your
vehicle’s systems may interfere with the operation
of sound equipment that has been added.Notice:The chime signals related to safety belts,
parking brake, and other functions of your vehicle
operate through the radio/entertainment system.
If that equipment is replaced or additional equipment
is added to your vehicle, the chimes may not
work. Make sure that replacement or additional
equipment is compatible with your vehicle before
installing it. SeeAccessories and Modifications
on page 5-3.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, the audio system can be
played even after the ignition is turned off. SeeRetained
Accessory Power (RAP) on page 2-24for more
information.
Setting the Time (Radio with Single
CD Player)
Enabling the Digital Radio Clock
Your vehicle has an analog clock as well as the digital
radio clock. At the time of new vehicle delivery, the
digital radio clock display should be disabled. If
you decide to use the digital radio clock as well as the
analog clock, you can change the setting to enable
the radio clock display.
3-98

Braking
SeeBrake System Warning Light on page 3-62.
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That is perception time. Then you have to bring up your
foot and do it. That is reaction time.
Average reaction time is about three-fourths of a
second. But that is only an average. It might be less
with one driver and as long as two or three seconds or
more with another. Age, physical condition, alertness,
coordination, and eyesight all play a part. So do alcohol,
drugs, and frustration. But even in three-fourths of a
second, a vehicle moving at 60 mph (100 km/h) travels
66 feet (20 m). That could be a lot of distance in an
emergency, so keeping enough space between
your vehicle and others is important.
And, of course, actual stopping distances vary greatly
with the surface of the road, whether it is pavement
or gravel; the condition of the road, whether it is
wet, dry, or icy; tire tread; the condition of your brakes;
the weight of the vehicle; and the amount of brake
force applied.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. Your brakes may not have time to cool between
hard stops. Your 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 engine ever stops while you are driving, brake
normally but do not pump your brakes. If you do,
the pedal may get harder to push down. If your 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 5-3.

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 your engine and begin to drive away,
ABS will check itself. You may hear a momentary motor
or clicking noise while this test is going on, and you may
even notice that your brake pedal moves a little.
This is normal.
If there is a problem with
ABS, this warning light will
stay on. SeeAnti-Lock
Brake System Warning
Light on page 3-63.
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 front wheel
and at both rear wheels.
4-7

Traction Control System (TCS)
Your vehicle has a traction control system that limits
wheel spin. This is especially useful in slippery road
conditions. The system operates only if it senses that the
front wheels are spinning too much or beginning to lose
traction. When this happens, the system works the front
brakes and reduces engine power (by closing the throttle
and managing engine spark) to limit wheel spin.
The traction control system and StabiliTrak
®warning
light will ash when the traction control system is limiting
wheel spin. SeeTraction Control System (TCS)
Warning Light on page 3-64andStabiliTrak
®Indicator
Light on page 3-64for more information. You may feel or
hear the system working, but this is normal.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
re-engage the cruise control. SeeCruise Control
on page 3-16orAdaptive Cruise Control on page 3-19
for more information.The SERVICE TRACTION CONTROL message, the
traction control system warning light and the StabiliTrak
®
warning light will come on to let you know if there is a
problem with the traction control system. SeeDIC
Warnings and Messages on page 3-76.
When this light and the SERVICE TRACTION
CONTROL message are on, the system will not limit
wheel spin. Adjust your driving accordingly.
The traction control system automatically comes on
whenever you start your vehicle. To limit wheel
spin, especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system off if you ever need to.
You can turn the system on or off at any time by
pressing the traction control system button located on
the console or on the end of the column shifter. The DIC
will display TRACTION CONTROL OFF when you
press the button.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modications
on page 5-3for more information.
