IntelliBeam™ Intelligent High-Beam
Headlamp Control System
If your vehicle has this feature, be sure to read this
entire section before using it.
IntelliBeam™ is an enhancement to your vehicle’s
headlamp system. Using a digital light sensor on your
rearview mirror, this system will turn the vehicle’s
high-beam headlamps on and off according to
surrounding traffic conditions.
The IntelliBeam™ system will turn your high-beam
headlamps on when it is dark enough, there is no other
traffic present, and the IntelliBeam system is enabled.
Turning On and Enabling IntelliBeam™
Press and release the IntelliBeam™ button on the inside
rear view mirror. The IntelliBeam™ indicator on the
mirror will turn on to let you know the system has
been turned on. Once the system has been turned
on, it will remain on each time the vehicle is started.
Additionally, the IntelliBeam system must be enabled.
To enable the IntelliBeam™ system, turn the exterior
lamp control to AUTO, with the turn signal/multifunction
lever in its neutral position. The High-Beam On Light
will appear on the instrument panel cluster when
the high-beams are on. SeeHighbeam On Light on
page 3-70.

When you are backing the vehicle and objects are
detected at the same time near both the front and rear
bumpers, both color-coded light displays will notify
you of objects close to each bumper. If there are objects
detected near both bumpers, the beeps will only be
sounded to notify that objects are close to the rear
bumper. However, if while you are backing and an object
comes within 1 ft (0.3 m) of the front bumper, and at
the same time there is another object further than
1 ft (0.3 m) from the rear bumper, then the beeps will
only be sounded to notify you of the closer object that is
near the front bumper.
When the System Does Not Seem to
Work Properly
If the UFRPA system will not activate due to a temporary
condition, the message PARKING ASSIST OFF will
be displayed on the DIC and a red light will be shown on
the rear UFRPA display when the shift lever is moved
into REVERSE (R). This occurs under the following
conditions:
The driver disables the system. SeeDIC Controls
and Displays on page 3-72.
The parking brake pedal is depressed.
A trailer was attached to your vehicle, or a bicycle
or an object was hanging out of your trunk during
your last drive when you turned off the vehicle. If the
attached objects are removed from your vehicle
before the start of your next drive, the system will
return to normal operation unless an object is
detected when the vehicle is shifted out of park.
If this occurs, you will have to wait until the vehicle
is driven forward above 15 mph (25 km/h) before
UFRPA will return to normal operation.
A bicycle or an object is attached to the front
bumper during your last drive when you turned off
the vehicle. If the attached objects are removed
from your vehicle before the start of your next drive,
the system will return to normal unless an object
is detected when the vehicle is shifted out of park.
If this occurs, UFRPA will return to normal
operation when the vehicle is driven forward
above 15 mph (25 km/h).
The ultrasonic sensors are not kept clean.
So be sure to keep your vehicle’s front and rear
bumpers free of mud, dirt, snow, ice and slush.
For cleaning instructions, seeWashing Your Vehicle
on page 5-86. If after cleaning the front and rear
bumpers and driving forward at a speed of
at least 15 mph (25 km/h), the DIC displays the
PARKING ASSIST OFF message, see your dealer.

Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part isn’t working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
If the warning light comes on, there is a brake problem.
Have your brake system inspected right away.
This light should come on briey when you turn the
engine on. If it does not come on then, have it xed
so it will be ready to warn you if there is a problem.When the ignition is on, the brake system warning light
will also come on when you set your parking brake.
The light will stay on if your parking brake does
not release fully. If it stays on after your parking brake is
fully released, it means you have a brake problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push, or the pedal may go closer to the
oor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeTowing
Your Vehicle on page 4-37.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is on.
Driving with the brake system warning light on
can lead to an accident. If the light is still on
after you have pulled off the road and stopped
carefully, have the vehicle towed for service. United StatesCanada

Anti-Lock Brake System
Warning Light
With the anti-lock brake
system, the light will come
on when your engine is
started and may stay on
for several seconds.
That is normal.
If the ABS warning light comes on and stays on, there
may be a problem with the antilock portion of the
brake system. If the red BRAKE light is not on, you still
have brakes, but you do not have antilock brakes.
SeeBrake System Warning Light on page 3-62.
If the light stays on, turn the ignition to OFF/ACC. If the
light comes on when you are driving, stop as soon as
possible and turn the ignition off. Then start the engine
again to reset the system. If the light still stays on, or
comes on again while you are driving, your vehicle needs
service. If the regular brake system warning light is not
on, you still have brakes, but you do not have anti-lock
brakes. If the regular brake system warning light is also
on, you do not have anti-lock brakes and there is a
problem with your regular brakes. SeeBrake System
Warning Light on page 3-62.The anti-lock brake system warning light should come
on briey when you turn the ignition key to RUN. If
the light does not come on then, have it xed so it
will be ready to warn you if there is a problem.
Low Tire Pressure Warning Light
This light will come on
briey as you start the
engine, for vehicles
equipped with the Tire
Pressure Monitor System.
It will then come on only when a at or low tire pressure
condition exists.
SeeTire Pressure Monitor System on page 5-59for
more information.

SERVICE BRAKE ASSIST
This message will display if there is a problem with the
brake system. The brake system warning light and the
anti-lock brake system warning light may also be
displayed on the instrument panel cluster. SeeBrake
System Warning Light on page 3-62andAnti-Lock Brake
System Warning Light on page 3-63for more information.
If this happens, stop as soon as possible and turn off the
vehicle. Restart the vehicle and check for the message
on the DIC display. If the message is displayed or
appears again when you begin driving, the brake system
needs service. See your GM dealer as soon as possible.
SeeBrakes on page 5-35for more information.
SERVICE BRAKE SYSTEM
This message will display if the ignition is on to inform
the driver that the brake uid level is low. Have the
brake system serviced by your GM dealer as soon
as possible.
SERVICE PARKING ASSIST
If your vehicle has the Ultrasonic Front and Rear
Parking Assist (UFRPA) system, this message will
display if there is a problem with the UFRPA system.
Do not use this system to help you park. SeeUltrasonic
Front and Rear Parking Assist (UFRPA) on page 3-38
for more information. See your GM dealer for service.
SERVICE POWER STEERING
Your vehicle may have a speed variable assist steering
system. SeeSteering on page 4-11.
This message will display if a problem is detected with
the speed variable assist steering system. When this
message is displayed, you may notice that the effort
required to steer the vehicle decreases or feels lighter,
but you will still be able to steer the vehicle.
SERVICE RADAR CRUISE
This message will display when the Adaptive Cruise
Control (ACC) system and the Forward Collision
Alert (FCA) system are disabled and need service.
See your GM dealer.

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.
