Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to or change
about the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Changing or moving any parts
of the front seats, safety belts, the airbag sensing
and diagnostic module, steering wheel, instrument
panel, roof-rail airbag modules, ceiling headliner
or pillar garnish trim, overhead console, front
sensors, side impact sensors, or airbag wiring can
affect the operation of the airbag system.
In addition, your vehicle has a passenger sensing
system for the right front passenger’s position, which
includes sensors that are part of the passenger’s
seat. The passenger sensing system may not
operate properly if the original seat trim is replaced
with non-GM covers, upholstery or trim, or with GM
covers, upholstery or trim designed for a different
vehicle. Any object, such as an aftermarket seat
heater or a comfort enhancing pad or device,
installed under or on top of the seat fabric, could alsointerfere with the operation of the passenger sensing
system. This could either prevent proper deployment
of the passenger airbag(s) or prevent the passenger
sensing system from properly turning off the
passenger airbag(s). SeePassenger Sensing
System on page 1-63.
If you have any questions about this, you should
contact Customer Assistance before you modify
your vehicle. The phone numbers and addresses for
Customer Assistance are in Step Two of the
Customer Satisfaction Procedure in this manual.
SeeCustomer Satisfaction Procedure on page 7-2.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out whether
this will affect my airbag system?
A:If you have questions, call Customer Assistance.
The phone numbers and addresses for Customer
Assistance are in Step Two of the Customer
Satisfaction Procedure in this manual. See
Customer Satisfaction Procedure on page 7-2.
In addition, your dealer/retailer and the service manual
have information about the location of the airbag
sensors, sensing and diagnostic module and airbag
wiring.

Cruise Control
With cruise control, you can maintain a speed of
approximately 25 mph (40 km/h) or more without
keeping your foot on the accelerator. This is helpful on
long trips. Cruise control does not work at speeds
below about 25 mph (40 km/h). When cruise control is
on, you will see a cruise light on the instrument
panel cluster.
When you apply your brakes, the cruise control
shuts off.{CAUTION:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do
not use your cruise control on winding roads
or in heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire
traction can cause excessive wheel slip, and
you could lose control. Do not use cruise
control on slippery roads.
If your vehicle is in cruise control when the Traction
Control System (TCS) begins to limit wheel spin,
the cruise control automatically turns off. SeeTraction
Control System (TCS) on page 4-5. When road
conditions let you safely use it again, you can turn the
cruise control back on.
3-16

Using Cruise Control on Hills
How well your cruise control works on hills depends
upon the vehicle speed, load, and the steepness of the
hills. When going up steep hills, you might have to
step on the accelerator pedal to maintain the vehicle’s
speed. When going downhill, you might have to brake or
shift to a lower gear to keep the vehicle’s speed
down. Applying the brake or shifting into a lower gear
ends cruise control. If you need to apply the brake
or shift to a lower gear due to the grade of the downhill
slope, you might not want to attempt to use the
cruise control feature.
Ending Cruise Control
To turn off the cruise control, step lightly on the brake
pedal, or press the cancel button on the steering wheel.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
Adaptive Cruise Control
If your vehicle has this feature, be sure to read this
entire section before using it.
The system operates on a radio frequency subject to
Federal Communications Commission (FCC) Rules and
with Industry Canada.This device complies with Part 15 of the FCC Rules.
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.
This device complies with RSS-210 of Industry 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.
Adaptive Cruise Control is an enhancement to traditional
cruise control. It allows you to keep cruise control
engaged in moderate traffic conditions without having to
constantly reset your cruise control. Adaptive Cruise
Control uses radar to detect a vehicle directly ahead in
your path, within a distance of 330 ft (100 m), and
operates at speeds above 25 mph (40 km/h). When it is
engaged by the driver, the system can apply limited
braking or acceleration of the vehicle automatically to
maintain a selected follow distance to the vehicle ahead.
3-19

CAUTION: (Continued)

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 weather limits visibility, such as
when in fog, rain, or snow conditions,
Adaptive Cruise Control 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.The Adaptive Cruise
controls are located on
the steering wheel.
The cruise control buttons are located on outboard side
of the steering wheel.
](On):This position turns on the system.
+ Res (Resume/Accelerate):Press this button to
make the vehicle resume to a previously set speed or to
increase the set speed when Adaptive Cruise Control
is already active.
3-21

Decreasing Set Speed While Using
Adaptive Cruise Control
Press the SET– button until you reach the lower speed
desired, then release it.
To slow down in very small amounts, briey press the
SET– button. Each time this is done, your set speed
decreases by 1 mph (1 km/h) slower.
Resuming a Set Speed
Suppose the Adaptive Cruise Control is set at a desired
speed and then the brakes are applied. This will turn
off the Adaptive Cruise Control. But it does not need to
be reset.
Once you are going about 25 mph (40 km/h) or more,
press the +RES button. Adaptive Cruise Control
will be engaged with the previously chosen set speed.
Selecting the Follow Distance (GAP)
When the system detects a slower moving vehicle, it will
adjust your vehicle’s speed and maintain the follow
distance (gap) you select.
Use the plus and minus buttons on the steering wheel
to adjust the follow distance.
Press the plus button to increase the distance or the
minus button to decrease the distance. The rst button
press shows the current follow distance setting on
the DIC. The 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
(one second to two 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 your vehicle 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 prefer to travel at a follow distance farther than
Adaptive Cruise Control allows, disengage the
system and drive manually.
3-24

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
<(Rear Defogger):Press the center of the right
control to turn the rear window defogger on or off.
Be sure to clear as much snow from the rear window
as possible. The rear window defogger will turn off
approximately 20 minutes after the button is pressed
if your vehicle is moving at slower vehicle speeds.
At higher vehicle speeds, the rear defogger may stay
on continuously. Each additional press will run the
defogger for approximately 10 minutes.
The heated outside rearview mirrors will heat to help
clear fog or frost from the surface of the mirror when
the rear window defogger is on.
Notice:Do not use a razor blade or sharp object
to clear the inside rear window. Do not adhere
anything to the defogger grid lines in the rear glass.
These actions may damage the rear defogger.
Repairs would not be covered by your warranty.
Outlet Adjustment
For the front outlets, use the thumbwheel located below
each outlet to change the direction of the airow. Use the
thumbwheel located next to the outlets to shut the airow
or to open the outlets and re-direct the air.
For the rear outlets, slide the lever left or right and up
or down to change the direction of the airow.
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 deectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of
objects to help circulate the air inside of your
vehicle more effectively.
