CD Messages
CHECK CD:If this message displays and/or the CD
comes out, it could be for one of the following reasons:
It is very hot. When the temperature returns to
normal, the CD should play.
You are driving on a very rough road. When the
road becomes smoother, the CD should play.
The CD is dirty, scratched, wet, or upside down.
The air is very humid. If so, wait about an hour and
try again.
The format of the CD might not be compatible.
There could have been a problem while burning
the CD.
The label could be caught in the CD player.
If the CD is not playing correctly, for any other reason,
try a known good CD.
If any error occurs repeatedly or if an error cannot be
corrected, contact your dealer/retailer. If the radio
displays an error message, write it down and provide it
to your dealer/retailer when reporting the problem.
XM Radio Messages
xL (Explicit Language Channels):These channels, or
any others, can be blocked at a customer’s request,
by calling 1-800-852-XMXM (9696).

updated, and no action is required. This process
should take no longer than 30 seconds.
No Signal:The system is functioning correctly, but the
vehicle is in a location that is blocking the XM™
signal. When the vehicle is moved into an open area,
the signal should return.
Loading XM:The audio system is acquiring and
processing audio and text data. No action is needed.
This message should disappear shortly.
CH Off Air:This channel is not currently in service.
Tune in to another channel.
CH Unavail:This previously assigned channel is no
longer assigned. Tune to another station. If this station
was one of the presets, choose another station for
that preset button.

information is available at this time on this channel.
The system is working properly.
3-60

Not Found:There are no channels available for the
selected category. The system is working properly.
XM Locked:The XM™ receiver in your vehicle may
have previously been in another vehicle. For security
purposes, XM™ receivers cannot be swapped between
vehicles. If this message is received after having
your vehicle serviced, check with your dealer/retailer.
Radio ID:If tuned to channel 0, this message will
alternate with the XM Radio 8 digit radio ID label.
This label is needed to activate the service.
Unknown:If this message is received when tuned to
channel 0, there may be a receiver fault. Consult
with your dealer/retailer.
Chk XMRcvr:If this message does not clear within a
short period of time, the receiver may have a fault.
Consult with your dealer/retailer.
Navigation/Radio System
Your vehicle may have a navigation radio system.
The navigation system has built-in features intended to
minimize driver distraction. Technology alone, no
matter how advanced, can never replace your own
judgment. See the Navigation System manual for some
tips to help you reduce distractions while driving.
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 does
not operate and LOCKED displays.
When the radio and vehicle are turned off, the blinking
red light indicates that THEFTLOCK
®is armed.
With THEFTLOCK
®activated, the radio does not
operate if stolen.
Radio Reception
Frequency interference and static during normal radio
reception can occur 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.
3-61

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 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
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.

Your Driving, the Road,
and Your Vehicle
Defensive Driving
Defensive driving means “always expect the
unexpected.” The rst step in driving defensively
is to wear your safety belt — SeeSafety Belts: They
Are for Everyone on page 1-10.
{CAUTION:
Assume that other road users (pedestrians,
bicyclists, and other drivers) are going to be
careless and make mistakes. Anticipate what
they might do and be ready. In addition:
Allow enough following distance between
you and the driver in front of you.
Focus on the task of driving.
Driver distraction can cause collisions
resulting in injury or possible death. These
simple defensive driving techniques could
save your life.
Drunk Driving
{CAUTION:
Drinking and then driving is very dangerous.
Your reexes, perceptions, attentiveness, and
judgment can be affected by even a small
amount of alcohol. You can have a serious — or
even fatal — collision if you drive after drinking.
Do not drink and drive or ride with a driver who
has been drinking. Ride home in a cab; or if
you are with a group, designate a driver who
will not drink.
Death and injury associated with drinking and driving
is a global tragedy.
Alcohol affects four things that anyone needs to drive
a vehicle: judgment, muscular coordination, vision,
and attentiveness.
Police records show that almost 40 percent of all motor
vehicle-related deaths involve alcohol. In most cases,
these deaths are the result of someone who was
drinking and driving. In recent years, more than
17,000 annual motor vehicle-related deaths have
been associated with the use of alcohol, with about
250,000 people injured.
4-2

For persons under 21, it is against the law in every
U.S. state to drink alcohol. There are good medical,
psychological, and developmental reasons for
these laws.
The obvious way to eliminate the leading highway
safety problem is for people never to drink alcohol
and then drive.
Medical research shows that alcohol in a person’s
system can make crash injuries worse, especially
injuries to the brain, spinal cord, or heart. This means
that when anyone who has been drinking — driver
or passenger — is in a crash, that person’s chance
of being killed or permanently disabled is higher than
if the person had not been drinking.
Control of a Vehicle
The following three systems help to control your vehicle
while driving — brakes, steering, and accelerator.
At times, as when driving on snow or ice, it is easy to
ask more of those control systems than the tires and
road can provide. Meaning, you can lose control of your
vehicle. SeeTraction Control System (TCS) on page 4-5.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3.
Braking
SeeBrake System Warning Light on page 3-33.
Braking action involves perception time and reaction
time. First, you have to decide to push on the brake
pedal. That is perception time. Then you have to bring
up your foot and do it. That is reaction time.
Average reaction time is about three-fourths of a
second. But that is only an average. It might be less
with one driver and as long as two or three seconds or
more with another. Age, physical condition, alertness,
coordination, and eyesight all play a part. So do alcohol,
drugs, and frustration. But even in three-fourths of a
second, a vehicle moving at 60 mph (100 km/h) travels
66 feet (20 m). That could be a lot of distance in an
emergency, so keeping enough space between
your vehicle and others is important.
And, of course, actual stopping distances vary greatly
with the surface of the road, whether it is pavement or
gravel; the condition of the road, whether it is wet, dry,
or icy; tire tread; the condition of the brakes; the weight
of the vehicle; and the amount of brake force applied.
Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic.
4-3

This is a mistake. The brakes might not have time to
cool between hard stops. The brakes will wear out
much faster if you do a lot of heavy braking. If you
keep pace with the traffic and allow realistic following
distances, you will eliminate a lot of unnecessary
braking. That means better braking and longer
brake life.
If your vehicle ever loses electrical power while you
are driving, brake normally but do not pump the brakes.
If you do, the pedal could get harder to push down.
If your vehicle loses electrical power, you will still have
some power brake assist. But you will use it when
you brake. Once the power assist is used up, it can take
longer to stop, the brake pedal will be harder to push,
and you might experience longer pedal travel.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3.Antilock Brake System (ABS)
Your vehicle has the Antilock Brake System (ABS),
an advanced electronic braking system that will
help prevent a braking skid.
When you start the engine and begin to drive away,
ABS will check itself. You might hear a momentary
motor or clicking noise while this test is going on.
This is normal.
If there is a problem with
ABS, this warning light will
stay on. SeeAntilock
Brake System Warning
Light on page 3-34.
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down.
If one of the wheels is about to stop rolling, the computer
will separately work the brakes at each wheel.
