2007 GMC SIERRA radio

Care of the CD and DVD Player
The use of CD lens cleaners for CDs is not
advised, due to the risk of contaminating the lens
of the CD optics with lubricants internal to the
CD mechanism.
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.
A vehicle with a sunroof might not get the
best performance from the XM™ system 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.

Notice:If the other vehicle’s system is not a
12-volt system with a negative ground,
both vehicles can be damaged. Only use
vehicles with 12-volt systems with negative
grounds to jump start your vehicle.
2. If you have a vehicle with a diesel engine with
two batteries, you should know before you
begin that, especially in cold weather, you may
not be able to get enough power from a
single battery in another vehicle to start your
diesel engine. If your vehicle has more
than one battery, use the battery that is closer
to the starter — this will reduce electrical
resistance. This is located on the passenger
side, in the rear of the engine compartment.
3. Get the vehicles close enough so the jumper
cables can reach, but be sure the vehicles are
not touching each other. If they are, it could
cause an unwanted ground connection.
You would not be able to start your vehicle,
and the bad grounding could damage the
electrical systems.To avoid the possibility of the vehicles rolling,
set the parking brake rmly on both vehicles
involved in the jump start procedure. Put
the automatic transmission in PARK (P) or a
manual transmission in NEUTRAL before
setting the parking brake. If you have a
four-wheel-drive vehicle, be sure the transfer
case is in a drive gear, not in NEUTRAL.
Notice:If you leave your radio or other
accessories on during the jump starting
procedure, they could be damaged. The repairs
would not be covered by your warranty.
Always turn off your radio and other
accessories when jump starting your vehicle.
4. Turn off the ignition on both vehicles.
Unplug unnecessary accessories plugged into
the cigarette lighter or the accessory power
outlets. Turn off the radio and all the
lamps that are not needed. This will avoid
sparks and help save both batteries. And it
could save the radio!

Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses
radio and sensor technology to check tire pressure
levels. If your vehicle has this feature, sensors
are mounted on each tire and wheel assembly,
except the spare tire. The TPMS sensors monitor
the air pressure in your vehicle’s tires and
transmit tire pressure readings to a receiver
located in the vehicle.
The TPMS is designed to alert the driver, if a low
tire pressure condition exists. If your vehicle has the
Driver Information Center (DIC), the driver may also
check tire pressure levels using the DIC.
When a low tire pressure condition is detected,
the TPMS will illuminate the low tire pressure
warning symbol located on the instrument panel
cluster. If your vehicle has the DIC feature, a
message to check the pressure in a specic tire
will also appear on the DIC display. The low
tire pressure warning symbol on the instrument
panel cluster and the CHECK TIRE PRESSURE
warning message on the DIC display will appear at
each ignition cycle until the tires are inated to
the correct ination pressure.For additional information and details about the
DIC operation and displays seeDIC Operation and
Displays (With DIC Buttons) on page 268orDIC
Operation and Displays (Without DIC Buttons)
on page 275andDIC Warnings and Messages on
page 279.
You may notice, during cooler weather conditions,
that the tire pressure monitor light, located on
the instrument panel cluster, and the CHECK TIRE
PRESSURE message will appear when the
vehicle is rst started and then turn off as you
start to drive the vehicle. This could be an early
indicator that the tire pressures are getting low and
need to be inated to the proper pressure.
Each tire, including the spare (if provided), should
be checked monthly when cold and inated to
the ination pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
ination pressure label. (If your vehicle has tires of
a different size than the size indicated on the
vehicle placard or tire ination pressure label, you
should determine the proper tire ination
pressure for those tires.)

Federal Communications Commission
(FCC) and Industry and Science

The Tire Pressure Monitor System (TPMS)
operates on a radio frequency and complies with
Part 15 of the FCC Rules. Operation is subject
to the following two conditions:
1. This device may not cause harmful
interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation.
The Tire Pressure Monitor System (TPMS)
operates on a radio frequency and complies
with RSS-210 of Industry and Science 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.
Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your
tires as soon as possible and check wheel
alignment. Also check for damaged tires or wheels.
SeeWhen It Is Time for New Tires on page 568
andWheel Replacement on page 573for
more information.
Make sure the spare tire is stored securely. Push,
pull, and then try to rotate or turn the tire. If it
moves, use the wheel wrench/hoist shaft to tighten
the cable. SeeChanging a Flat Tire on page 576.
If your vehicle has dual rear wheels, also see
Dual Tire Operation on page 560.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The
rst rotation is the most important. SeeScheduled
Maintenance (Gasoline Engine) on page 623.

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer
rst. Some electrical equipment can damage
your vehicle and the damage would not
be covered by your warranty. Some add-on
electrical equipment can keep other
components from working as they should.
Add-on equipment can drain your vehicle’s battery,
even if your vehicle is not operating.
Your vehicle has an airbag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 102.
Windshield Wiper Fuses
The windshield wiper motor is protected by an
internal circuit breaker and a fuse. If the motor
overheats due to heavy snow, etc., the wiper will
stop until the motor cools. If the overload is
caused by some electrical problem and not snow,
etc., be sure to get it xed.
Power Windows and Other Power
Options
Circuit breakers protect the power windows and
other power accessories. If the current load is too
heavy, the circuit breaker opens and then
closes after a cool down period, protecting the
circuit until the problem is xed or goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected
from short circuits by a combination of fuses,
circuit breakers and fusible thermal links.
This greatly reduces the chance of res caused by
electrical problems.
Look at the silver-colored band inside the fuse. If
the band is broken or melted, replace the fuse.
Be sure you replace a bad fuse with a new one of
the identical size and rating.
If you ever have a problem on the road and do not
have a spare fuse, you can borrow one that has the
same amperage. Just pick some feature of your
vehicle that you can get along without, like the radio
or cigarette lighter, and use its fuse if it is the
correct amperage. Replace it as soon as you can.
