Theft-Deterrent Feature
THEFTLOCK®is designed to discourage theft
of your vehicle’s radio. The feature works
automatically by learning a portion of the Vehicle
Identication Number (VIN). If the radio is
moved to a different vehicle, it will not operate
and LOCKED will appear on the display.
When the radio and vehicle are turned off, the
blinking red light indicates that THEFTLOCK
®is
armed.
With THEFTLOCK
®activated, the radio will not
operate if stolen.
Audio Steering Wheel Controls
Your vehicle has audio
steering wheel controls,
they may differ
depending on your
vehicle’s options. Some
audio controls can
be adjusted at
the steering wheel.
They include the
following:
xw(Next/Previous):Press the up or the down
arrow to go to the next or to the previous radio
station stored as a favorite.

Radio Reception
You may experience frequency interference and
static during normal radio reception if items
such as cellphone 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.
336

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 will 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 will give the best sound, but FM signals
will reach only 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.
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 XM SIGNAL to indicate
interference.

Care of Your CDs and DVDs
Handle CDs carefully. Store them in their original
cases or other protective cases and away from
direct sunlight and dust. The CD player scans the
bottom surface of the disc. If the surface of a
CD is damaged, such as cracked, broken,
or scratched, the CD will not play properly or not
at all. If the surface of a CD is soiled, take a
soft, lint free cloth or dampen a clean, soft cloth in
a mild, neutral detergent solution mixed with
water, and clean it. Make sure the wiping process
starts from the center to the edge.
Do not touch the bottom side of a CD while
handling it; this could damage the surface. Pick up
CDs by grasping the outer edges or the edge of
the hole and the outer edge.
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.
Rear Side Window Antenna
Your AM-FM antenna is located in the passenger
rear side window. Be sure that the inside
surfaces of the rear side window is not scratched
and that the lines on the glass are not damaged.
If the inside surfaces are damaged, they could
interfere with radio reception.
Notice:Using a razor blade or sharp object to
clear the inside of the rear side windows
may affect radio reception or damage the
antenna. Repairs would not be covered by your
warranty. Do not clear the inside of the rear
side windows with sharp objects.
338

Notice:Do not apply aftermarket glass tinting
with metallic lm. The metallic lm in some
tinting materials will interfere with or distort the
incoming radio reception. Any damage
caused to your antenna due to metallic tinting
materials will not be covered by your
warranty.
Because this antenna is built into your rear side
window, there is a reduced risk of damage caused
by car washes and vandals.
If you choose to add an aftermarket cellular
telephone to your vehicle, and the antenna needs
to be attached to the glass, be sure that you
do not damage the grid lines for the AM-FM
antennas or place the cellular telephone antenna
over the grid lines.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.

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.
3. 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!4. Open the hood on the other vehicle and
locate the positive (+) and negative (−)
terminal locations on that vehicle.
Your vehicle has a remote positive (+) jump
starting terminal and a remote negative (−)
jump starting terminal. You should always use
these remote terminals instead of the
terminals on the battery.
The remote positive (+) terminal, if equipped, is
located under a red plastic cover at the positive
battery post. To uncover the remote positive (+)
terminal, open the red plastic cover.
The remote negative (−) terminal is a stud
located on the right front of the engine, where
the negative battery cable attaches.

High-Speed Operation
{CAUTION:
Driving at high speeds, 100 mph
(160 km/h) or higher, puts an additional
strain on tires. Sustained high-speed
driving causes excessive heat build up
and can cause sudden tire failure. You
could have a crash and you or others
could be killed. Some high-speed rated
tires require ination pressure adjustment
for high speed operation. When speed
limits and road conditions are such that
a vehicle can be driven at high speeds,
make sure the tires are rated for high
speed operation, in excellent condition,
and set to the correct cold tire ination
pressure for the vehicle load.If your vehicle has P265/65R18 or P275/55R20
size tires and you will be driving at high speeds,
speeds of 100 mph (160 km/h) or higher, set
the cold ination pressure to 3 psi (20 kPa) above
the recommended tire pressure shown on the
Tire and Loading Information Label. When you
end this high-speed driving, return the tires to the
cold ination pressure shown on the Tire and
Loading Information label. SeeLoading Your
Vehicle on page 392andInation - Tire Pressure
on page 488.
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.
