LOCKED could display.
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.
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.

Traction Control System (TCS)
Your vehicle may have a Traction Control System (TCS)
that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if it
senses that one or both of the front wheels are
spinning or beginning to lose traction. When this
happens, the system works the front brakes and reduces
engine power to limit wheel spin. It may also upshift
the transmission to limit wheel spin. You may feel
or hear the system working, but this is normal.
The TRACTION CONTROL ACTIVE message on the
Driver Information Center (DIC) will be displayed
when the system is limiting wheel spin.
If the vehicle is in cruise control when the TCS begins
to limit wheel spin, the cruise control will automatically
disengage. When road conditions allow safe use of
the cruise control, it can be used again. SeeCruise
Control on page 3-10.
The TCS operates in all transmission shift lever
positions. But the system can upshift the transmission
only as high as the shift lever position that was chosen,
so use the lower gears only when necessary. See
Automatic Transmission Operation on page 2-29.This light, along with the
TRACTION CONTROL
OFF message, will display
on the DIC for three
seconds when the TCS is
not on.
If there is a problem with the system, the SERVICE
TRACTION SYSTEM message will also come on in the
DIC. When this warning light is on, the system will
not limit wheel spin. Adjust driving accordingly.
To limit wheel spin, especially in slippery road
conditions, you should always leave the TCS on. But
you can turn the system off if you ever need to. The TCS
should be turned off if the vehicle ever gets stuck in
sand, mud or snow and rocking the vehicle is required.
SeeRocking Your Vehicle to Get It Out on page 4-21
andIf Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on page 4-20.
To turn the TCS on or off, press the TCS button located
above the radio.
