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 SIGNAL to indicate
interference.
Care of Your CDs
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 Player
Do not use CD lens cleaners for CD players
because the lens of the CD optics can become
contaminated by lubricants.

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 transaxle 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 154.The TCS operates in all transaxle shift lever
positions. But the system can upshift the transaxle
only as high as the shift lever position that was
chosen, so use the lower gears only when
necessary. SeeAutomatic Transaxle Operation
on page 114.
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.

The ETS operates in all transaxle shift lever
positions. But the system can upshift the transaxle
only as high as the chosen shift lever position,
so use the lower gears only when necessary. See
Automatic Transaxle Operation on page 114.
This light, along with the
TRACTION CONTROL
OFF message, will
display on the DIC for
three seconds when the
ETS 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 your
driving accordingly.
To limit wheel spin, especially in slippery road
conditions, you should always leave the ETS on.
But you can turn the system off if you ever
need to. The ETS should be turned off if the
vehicle ever gets stuck in sand, mud or snow and
rocking the vehicle is required.To turn the ETS on or off, press the ETS button
located above the radio.
When the ETS is turned off, the ETS warning light
will come on along with the TRACTION
CONTROL OFF message on the DIC. It will
disappear when the ETS is turned back on. If the
ETS is limiting wheel spin when the traction
control button is pressed, the ETS warning light
will come on and the ETS will turn off right away.
StabiliTrak®System
Your vehicle may be equipped with a vehicle
stability enhancement system called StabiliTrak®.
It is an advanced computer controlled system
that assists you with directional control of
the vehicle in difficult driving conditions.
StabiliTrak
®activates when the computer senses
a discrepancy between your intended path
and the direction the vehicle is actually traveling.
StabiliTrak
®selectively applies braking pressure
at any one of the vehicle’s brakes to help steer the
vehicle in the direction which you are steering.
