{CAUTION:
·On winding roads, ACC may not detect a
vehicle ahead. You could crash into a
vehicle ahead of you. Do not use ACC on
winding roads.
·In heavy stop-and-go traffic, ACC may not
have time to slow your vehicle enough to
avoid a collision because of the rapidly
changing traffic conditions. Do not use
ACC in heavy stop-and-go traffic.
·On slippery roads, fast changes in tire
traction can cause needless wheel
spinning, and you could lose control. Do
not use cruise control on slippery roads.
·When visibility is low, such as in fog, rain
or snow, you can not tell how far away
things are and ACC performance is limited.
There may not be enough distance to
adapt to the changing traffic conditions.
Do not use cruise control when visibility
is low.Some of the ACC controls
are located on the end of
the multifunction lever.
9(Off):This position turns the system off.
R(On):This position turns the system on.
S(Resume/Increase):Push the switch to this symbol

Selecting the Follow Distance (GAP)
When ACC detects a slower moving vehicle, it will
adjust your vehicle's speed and maintain the follow
distance (gap) you select.
Use the GAP button on
the steering wheel to
adjust the follow distance.
Press the top of the button to increase the distance or
the bottom of the button to decrease the distance.
The ®rst button press will show you the current follow
distance setting on the HUD. Your current follow
distance setting will be maintained until you change it.
There are six follow distances to choose from. The
follow distance selection ranges from near to far
(1 second to 2 seconds follow time).The distance maintained for a selected follow distance
will vary based on vehicle speed. The faster the
vehicle speed the further back you will follow. Consider
traffic and weather conditions when selecting the
follow distance. The range of selectable distances may
not be appropriate for all drivers and driving conditions.
If you choose to travel at a distance farther than
ACC allows, disengage ACC and drive manually.
A graphic on the HUD indicates the selected follow
distance. This picture shows a maximum follow distance.
The vehicles will move closer as you select a smaller
follow distance.

!- (Brightness):This button is used to adjust the
brightness of the HUD and the instrument panel cluster.
DIMMER:This button is used to select the HUD or
the instrument panel cluster to adjust the brightness.
HUD:This button is used to adjust the vertical position
of the HUD display.
To adjust the HUD so you can see it properly, do the

is at a speci®c angle and position, the sun's rays can
shine back into the HUD. When this occurs, the display
device within the HUD will be temporarily illuminated.
The event will end when the vehicle's angle to the
sun changes.

Operation Tips
·
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ¯ow of air into your vehicle.
·Use of non-GM approved hood de¯ectors may
adversely affect the performance of the system.
·Keep the area around the base of the instrument
panel console and air path under the seats clear
of objects to help circulate the air inside of
your vehicle more effectively.
Passenger Compartment Air Filter
The passenger compartment air ®lter removes certain
odor and particles from the air including pollen and dust
particles. Reductions in air¯ow, which may occur
more often in dusty areas, indicate that the ®lter may
need to be replaced early.
The ®lter should be replaced as part of the routine
scheduled maintenance. See
Scheduled Maintenance
on page 6-4for more information.
The passenger compartment air ®lter is located on the
passenger's side of the engine compartment near
the battery. See
Engine Compartment Overview on
page 5-12for more information on location.
To check or replace the air ®lter, do the following:
1. With the hood open, unlatch and remove the access
panel.
2. Pull the old ®lter out of the housing.
3. Insert the new ®lter into the housing. The ®lter
should be fully inserted with the arrows pointing up.
4. Reinstall the air ®lter access panel.

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 light stays on, turn the ignition off. Or, 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. See
ªService ABSº under
DIC Warnings and Messages
on page 3-57.
The anti-lock brake system warning light will come on
brie¯y when you turn the ignition on. This is normal.
If the light does not come on then, have it ®xed so it will
be ready to warn you if there is a problem.

The light will also come on while the Stabilitrak
žsystem
warms up and the STABILITRAK WARMING message
will be displayed in the Driver Information Center (DIC).
If it stays on, or comes on and the DIC shows a
SERVICE TRACTION SYS message when you are
driving, there is a problem with your TCS and your
vehicle needs service. When this light is on, the system
will not limit wheel spin. Adjust your driving accordingly.
If the driver turns off TCS by pressing the button on
the console, the TCS system light will come on and the
TRACTION SYSTEM-OFF message will show on
the DIC.
