Rear Seat Audio (RSA)
(Option B, Uplevel)
Your vehicle may have this type of rear seat
audio (RSA) system, if it has this feature, it will
allow rear seat passengers to listen to and control
any of the following audio sources: AM/FM
tuner, front CD player, and XM™ Satellite Radio
Service (if equipped). However, the rear seat
passengers can only control the sources that the
front seat passengers are not listening to. For
example, rear seat passengers may listen to a CD
in the front radio and control it while the driver
listens to the radio through the front speakers.
The rear seat passengers have control of
the volume for each set of headphones.

Selecting Your Mobile Digital Media as the
Active Source
Your radio and rear seat entertainment system
communicate with the GM Mobile Digital Media
system, as one compact unit that can be accessed
by everyone seated inside the vehicle. The GM
Mobile Digital Media system can hold thousands of
songs, hours of videos, and hundreds of games.
To help use this system, see the following
“Quick Start” information:
Front seat driver and passenger, use the radio
and steering wheel controls to access the music
collection with PhatNoise Voice Index™
technology. The preset buttons can be used to
select the browsing category. The Next,
Previous, and Seek buttons can be used to
browse within a browsing category. Browse the
music collection by artist, album, genre, or
custom playlist as the system uses the voice
mode to announce these selections. See “Using
the GM Mobile Digital Media System for Front
Seat Audio Entertainment” later in this manual.
Rear seat passengers, use the wireless DVD
remote control to navigate the menu displayed
on the overhead DVD video screen, then selectto play music, videos, or games. A dedicated
game controller is included with the Mobile
Digital Media package. See “Using the GM
Mobile Digital Media System for Rear Seat
Entertainment” later in this manual.
Your vehicle may have audio steering wheel
controls. Some audio controls can be adjusted at
the steering wheel. SeeAudio Steering Wheel
Controls on page 341in your owner manual.
If your vehicle has the OnStar
®/Mute audio
steering wheel control, read the following
instructions.

According to the American Medical Association, a
180 lb (82 kg) person who drinks three 12 ounce
(355 ml) bottles of beer in an hour will end up with
a BAC of about 0.06 percent. The person would
reach the same BAC by drinking three 4 ounce
(120 ml) glasses of wine or three mixed drinks if
each had 1-1/2 ounces (45 ml) of liquors like
whiskey, gin, or vodka.It is the amount of alcohol that counts. For
example, if the same person drank three double
martinis (3 ounces or 90 ml of liquor each)
within an hour, the person’s BAC would be close
to 0.12 percent. A person who consumes food
just before or during drinking will have a somewhat
lower BAC level.
There is a gender difference, too. Women
generally have a lower relative percentage of body
water than men. Since alcohol is carried in body
water, this means that a woman generally will
reach a higher BAC level than a man of her same
body weight will when each has the same
number of drinks.
The law in most U.S. states, and throughout
Canada, sets the legal limit at 0.08 percent. In
some other countries, the limit is even lower. For
example, it is 0.05 percent in both France and
Germany. The BAC limit for all commercial drivers
in the United States is 0.04 percent.
The BAC will be over 0.10 percent after three to
six drinks (in one hour). Of course, as we have
seen, it depends on how much alcohol is in the
drinks, and how quickly the person drinks them.

The traction you can get in a curve depends on
the condition of your tires and the road surface, the
angle at which the curve is banked, and your
speed. While you are in a curve, speed is the one
factor you can control.
Suppose you are steering through a sharp curve.
Then you suddenly apply the brakes. Both
control systems — steering and braking — have
to do their work where the tires meet the road.
Unless you have four-wheel anti-lock brakes,
adding the hard braking can demand too much of
those places. You can lose control.
The same thing can happen if you are steering
through a sharp curve and you suddenly
accelerate. Those two control systems — steering
and acceleration — can overwhelm those
places where the tires meet the road and make
you lose control. SeeTraction Control System
(TCS) on page 353andStabiliTrak
®System on
page 355.What should you do if this ever happens? Ease up
on the brake or accelerator pedal, steer the
vehicle the way you want it to go, and slow down.
Speed limit signs near curves warn that you
should adjust your speed. Of course, the posted
speeds are based on good weather and road
conditions. Under less favorable conditions you will
want to go slower.
If you need to reduce your speed as you approach
a curve, do it before you enter the curve, while
your front wheels are straight ahead.
Try to adjust your speed so you can “drive”
through the curve. Maintain a reasonable, steady
speed. Wait to accelerate until you are out of
the curve, and then accelerate gently into
the straightaway.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modi cations on page 400.
