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 the 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, front sensors,
or airbag wiring can affect the
operation of the airbag system.
In addition, the vehicle has a
passenger sensing system for the
right front passenger 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 also interfere
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). See
Passenger Sensing System
on page 1-30.
If you have any questions about
this, you should contact Customer
Assistance before you modify
your vehicle. The phone numbersand addresses for Customer
Assistance are in Step Two of the
Customer Satisfaction Procedure
in this manual. SeeCustomer
Satisfaction Procedure on
page 11-1.
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.
SeeCustomer Satisfaction
Procedure on page 11-1.
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.

Radio Reception
Frequency interference and static
can occur during normal radio
reception if items such as cell phone
chargers, vehicle convenience
accessories, and external electronic
devices are plugged into the
accessory power outlet. If there is
interference or static, unplug the item
from the accessory power outlet.
AM
The range for most AM stations is
greater than for FM, especially at
night. The longer range can cause
station frequencies to interfere with
each other. For better radio
reception, most AM radio stations
boost the power levels during the
day, and then reduce these levels
during the night. Static can also
occur when things like storms and
power lines interfere with radio
reception. When this happens, try
reducing the treble on your radio.
FM Stereo
FM stereo gives the best sound,
but FM signals only reach about
10 to 40 miles (16 to 65 km).
Tall buildings or hills can interfere
with FM signals, causing the
sound to fade in and out.
Fixed Mast Antenna
The xed mast antenna can
withstand most car washes without
being damaged, or it can be
removed. If the mast should ever
become slightly bent, straighten
it out by hand. If the mast is badly
bent, replace it.
Check occasionally to make sure
the mast is still tightened to the
antenna base located on the roof of
the vehicle.

PassengerTires
Your new vehicle comes with
high-quality tires made by
a leading tire manufacturer.
If you ever have questions about
the tire warranty and where to
obtain service, see the “Limited
Warranty, Maintenance and
Owner Assistance Information”
manual for details.
{CAUTION
Poorly maintained and
improperly used tires are
dangerous.
Overloading your tires can
cause overheating as a
result of too much exing.
You could have an air-out
and a serious accident.
SeeLoading the Vehicle
on page 8-30.
(Continued)
CAUTION (Continued)
Underinated tires pose
the same danger as
overloaded tires.
The resulting accident
could cause serious
injury. Check all tires
frequently to maintain the
recommended pressure.
Tire pressure should be
checked when your tires
are cold. SeeInflation - Tire
Pressure on page 9-46.
Overinated tires are more
likely to be cut, punctured,
or broken by a sudden
impact — such as when
you hit a pothole. Keep
tires at the recommended
pressure.
