Radio Data System (RDS)
The audio system has a Radio Data System (RDS). The
RDS feature is available for use only on FM stations
that broadcast RDS information. This system relies upon
receiving specic information from these stations and
only works when the information is available. While the
radio is tuned to an FM-RDS station, the station
name or call letters displays. In rare cases, a radio
station could broadcast incorrect information that causes
the radio features to work improperly. If this happens,
contact the radio station.

the lower right side of the faceplate. This is not an
audio output; do not plug the headphone set into the
front auxiliary input jack. An external audio device such
as an iPod, laptop computer, MP3 player, CD player,
or cassette tape player, etc. can be connected to
the auxiliary input jack for use as another audio source.
Drivers are encouraged to set up any auxiliary device
while the vehicle is in PARK (P). SeeDefensive Driving
on page 4-2for more information on driver distraction.
To use a portable audio player, connect a 3.5 mm
(1/8 inch) cable to the radio’s front auxiliary input jack.
When a device is connected, press the radio CD/AUX
button to begin playing audio from the device over
the vehicle speakers.

device’s volume to the loudest level.
It is always best to power your portable audio device

and does not indicate “No Aux Input Device”. If a
front auxiliary device is connected, the DVD/CD AUX
button cycles through all available options, such
as: DVD slot, CD slot, Front Auxiliary, and Rear Auxiliary

Using ABS
Do not pump the brakes. Just hold the brake pedal
down rmly and let antilock work for you. You might feel
the brakes vibrate or notice some noise, but this is
normal.
Braking in Emergencies
With ABS, you can steer and brake at the same time. In
many emergencies, steering can help you more than
even the very best braking.
Locking Rear Axle
If your vehicle has this feature, your locking rear axle
can give you additional traction on snow, mud, ice, sand
or gravel. It works like a standard axle most of the
time, but when one of the rear wheels has no traction
and the other does, this feature will allow the wheel with
traction to move the vehicle.
StabiliTrak®System
Your vehicle may have the StabiliTrak®system which
combines antilock brake, traction and stability control
systems and helps the driver maintain directional control
of the vehicle in most driving conditions.When you rst start your vehicle and begin to drive away,
the system performs several diagnostic checks to ensure
there are no problems. You may hear or feel the system
working. This is normal and does not mean there is a
problem with your vehicle. The system should initialize
before the vehicle reaches 20 mph (32 km/h). In some
cases, it may take approximately two miles of driving
before the system initializes.
If the system fails to turn on or activate, the StabiliTrak
®
light along with one of the following messages will be
displayed on the Driver Information Center (DIC):
TRACTION CONTROL OFF, SERVICE TRACTION
CONTROL, STABILITRAK OFF, SERVICE
STABILITRAK. If these DIC messages appear, make
sure the StabiliTrak
®system has not been turned off
using the StabiliTrak®on/off button. Then turn the
steering wheel clockwise from the nine o’clock position to
the three o’clock position. If this clears the message(s),
your vehicle does not need servicing. If this does not
clear the message(s), then turn the vehicle off, wait
15 seconds, and then turn it back on again to reset the
system. If any of these messages still appear on the
Driver Information Center (DIC), your vehicle should be
taken in for service. For more information on the DIC
messages, seeDriver Information Center (DIC) on
page 3-55.

Steering in Emergencies
There are times when steering can be more effective than
braking. For example, you come over a hill and nd a
truck stopped in your lane, or a car suddenly pulls out
from nowhere, or a child darts out from between parked
cars and stops right in front of you. You can avoid these
problems by braking — if you can stop in time. But
sometimes you cannot; there is not room. That is the time
for evasive action — steering around the problem.
Your vehicle can perform very well in emergencies like
these. First, apply the brakes. SeeBraking on
page 4-4. It is better to remove as much speed as you
can from a possible collision. Then steer around the
problem, to the left or right depending on the space
available.
An emergency like this requires close attention and a
quick decision. If you are holding the steering wheel at
the recommended 9 and 3 o’clock positions, you
can turn it a full 180 degrees very quickly without
removing either hand. But you have to act fast, steer
quickly, and just as quickly straighten the wheel
once you have avoided the object.
The fact that such emergency situations are always
possible is a good reason to practice defensive driving
at all times and wear safety belts properly.
