XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio
reception from coast-to-coast in the 48 contiguous
United States, and in Canada. Just as with FM,
tall buildings or hills can interfere with satellite radio
signals, causing the sound to fade in and out. In
addition, traveling or standing under heavy foliage,
bridges, garages, or tunnels may cause loss of the XM™
signal for a period of time. The radio may display NO
SIGNAL to indicate interference.
Fixed Mast Antenna
The xed mast antenna can withstand most car washes
without being damaged. 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 its base. If tightening is required, tighten
by hand, then with a wrench one quarter turn.
XM™ Satellite Radio Antenna
System
The XM™ Satellite Radio antenna is located on the roof
of your vehicle. Keep this antenna clear of snow and
ice build up for clear radio reception.
If your vehicle has a sunroof, the performance of the
XM™ system may be affected if the sunroof is open.
Loading items onto the roof of your vehicle can interfere
with the performance of the XM™ system. Make sure
the XM™ Satellite Radio antenna is not obstructed.
Chime Level Adjustment
The radio is used to adjust the vehicle’s chime level.
To change the volume level of the chime, press and hold
pushbutton 6 with the ignition on and the radio power off.
The volume level will change from the normal level to
loud, and LOUD CHIME will appear on the radio display.
To change back to the default or normal setting, press
and hold pushbutton 6 again. The volume level will
change from the loud level to normal, and NORMAL
CHIME will appear on the radio display. Removing the
radio and not replacing it with a factory radio or chime
module will disable vehicle chimes.

High pressure car washes may cause water to enter the
vehicle. Avoid using high pressure washes closer
than 12 inches (30 cm) to the surface of the vehicle.
Use of power washers exceeding 1,200 psi (8 274 kPa)
can result in damage or removal of paint and decals.
Cleaning Exterior Lamps/Lenses
Use only lukewarm or cold water, a soft cloth and a car
washing soap to clean exterior lamps and lenses.
Follow instructions underWashing Your Vehicle on
page 5-103.
Finish Care
Occasional waxing or mild polishing of your vehicle by
hand may be necessary to remove residue from the
paint nish. You can get approved cleaning products
from your dealer/retailer. SeeVehicle Care/Appearance
Materials on page 5-107.
If your vehicle has a basecoat/clearcoat paint nish, the
clearcoat gives more depth and gloss to the colored
basecoat. Always use waxes and polishes that are
non-abrasive and made for a basecoat/clearcoat paint
nish.Notice:Machine compounding or aggressive
polishing on a basecoat/clearcoat paint nish may
damage it. Use only non-abrasive waxes and
polishes that are made for a basecoat/clearcoat paint
nish on your vehicle.
Foreign materials such as calcium chloride and other
salts, ice melting agents, road oil and tar, tree sap, bird
droppings, chemicals from industrial chimneys, etc.,
can damage your vehicle’s nish if they remain on
painted surfaces. Wash the vehicle as soon as possible.
If necessary, use non-abrasive cleaners that are marked
safe for painted surfaces to remove foreign matter.
Exterior painted surfaces are subject to aging, weather
and chemical fallout that can take their toll over a period
of years. You can help to keep the paint nish looking
new by keeping your vehicle garaged or covered
whenever possible.
Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly to keep
their luster. Washing with water is all that is usually
needed. However, you may use chrome polish on
chrome or stainless steel trim, if necessary.
Use special care with aluminum trim. To avoid damaging
protective trim, never use auto or chrome polish,
steam or caustic soap to clean aluminum. A coating of
wax, rubbed to high polish, is recommended for all
bright metal parts.

To read data recorded by an EDR, special equipment is
required, and access to the vehicle or the EDR is
needed. In addition to the vehicle manufacturer, other
parties, such as law enforcement, that have the special
equipment, can read the information if they have
access to the vehicle or the EDR.
GM will not access this data or share it with others
except: with the consent of the vehicle owner or, if the
vehicle is leased, with the consent of the lessee; in
response to an official request of police or similar
government office; as part of GM’s defense of litigation
through the discovery process; or, as required by
law. Data that GM collects or receives may also be used
for GM research needs or may be made available to
others for research purposes, where a need is shown
and the data is not tied to a specic vehicle or
vehicle owner.
OnStar®
If your vehicle has OnStar and you subscribe to the
OnStar services, please refer to the OnStar Terms and
Conditions for information on data collection and
use. See alsoOnStar
®System on page 2-48in this
manual for more information.
Navigation System
If your vehicle has a navigation system, use of the
system may result in the storage of destinations,
addresses, telephone numbers, and other trip
information. Refer to the navigation system operating
manual for information on stored data and for deletion
instructions.
Radio Frequency
Identication (RFID)
RFID technology is used in some vehicles for functions
such as tire pressure monitoring and ignition system
security, as well as in connection with conveniences
such as key fobs for remote door locking/unlocking and
starting, and in-vehicle transmitters for garage door
openers. RFID technology in GM vehicles does not use
or record personal information or link with any other
GM system containing personal information.
