Sensing System for Passenger
Airbag
The passenger sensing system, if equipped, will turn off
the right front passenger frontal airbag under certain
conditions. The driver airbags, seat‐mounted side
impact airbags and roof‐rail airbags are not affected
by this.
If the vehicle has one of the indicators pictured in the
following illustrations, then the vehicle has a passenger
sensing system for the right front passenger position.
The passenger airbag status indicator, if equipped, will
be visible on the overhead console when the vehicle is
started.

Outlet Adjustment
Use the air outlets located in the center and on the side
of the instrument panel to direct the airflow. Use the
thumbwheels near the air outlets to open or close off
the airflow.
Operation Tips
.Clear away any ice, snow, or leaves from air inlets
at the base of the windshield that could block the
flow of air into the vehicle.
.Keep the path under the front seats clear of
objects to help circulate the air inside of the vehicle
more effectively.
.Use of non‐GM approved hood deflectors can
adversely affect the performance of the system.
Check with your dealer/retailer before adding
equipment to the outside of the vehicle.
Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to the
warning lights and gages could prevent injury.
Warning lights come on when there might be or there is
a problem with one of the vehicle's functions. Some
warning lights come on briefly when the engine is
started to indicate they are working.
Gages can indicate when there might be or there is a
problem with one of the vehicle's functions. Often gages
and warning lights work together to indicate a problem
with the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there
could be a problem, check the section that explains
what to do. Follow this manual's advice. Waiting to do
repairs can be costly and even dangerous.

Using the Auxiliary Input Jack
The radio system has an auxiliary input jack located on
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, etc. can
be connected to the auxiliary input jack for use as
another source for audio listening.
Drivers are encouraged to set up any auxiliary device
while the vehicle is in P (Park). SeeDefensive Driving
on page 5‑2for more information on driver distraction.
To use a portable audio player, connect a 3.5 mm
(1/8 in) 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.
For optimal sound quality, increase the portable audio
device's volume to the loudest level.
It is always best to power the portable audio device
through its own battery while playing.
O(Power/Volume): Turn clockwise or
counterclockwise to increase or decrease the
volume of the portable player. Additional volume
adjustments might have to be made from the portable
device if the volume is not loud or soft enough. BAND :
Press to listen to the radio when a portable
audio device is playing. The portable audio device
continues playing.
CD/AUX (CD/Auxiliary) : Press to play a CD when a
portable audio device is playing. Press again and the
system begins playing audio from the connected
portable audio player. If a portable audio player is not
connected, “No Input Device Found” displays.
DVD/CD AUX (CD/Auxiliary) : Press to cycle through
DVD, CD, or Auxiliary when listening to the radio. The
DVD/CD text tab and a message showing track or
chapter number displays when a disc is in either slot.
Press again and the system automatically searches for
an auxiliary input device, such as a portable audio
player. If a portable audio player is not connected, “No
Aux Input Device” displays. If a disc is in both the DVD
slot and the CD slot the DVD/CD AUX button cycles
between the two sources and 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 (if available). See “Using the Auxiliary
Input Jack(s)” later in this section, or “Audio/Video (A/V)
Jacks” under,Rear Seat Entertainment (RSE) System
on page 4‑126for more information.

Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim of the headlamps have been preset at
the factory and should need no further adjustment.
However, if the vehicle is damaged in a crash, the aim
of the headlamps may be affected and adjustment may
be necessary.
If oncoming vehicles flash their high beams at you, this
may mean the vertical aim of your headlamps needs to
be adjusted.
It is recommended that the vehicle is taken to your
dealer/retailer for service if the headlamps need to be
adjusted. It is possible however, to re-aim the
headlamps as described.The vehicle should:.Be placed so the headlamps are 25 ft. (7.6 m) from
a light colored wall.
.Have all four tires on a level surface which is level
all the way to the wall.
.Be placed so it is perpendicular to the wall.
.Not have any snow, ice, or mud on it.
.Be fully assembled and all other work stopped
while headlamp aiming is being performed.
.Normally loaded with a full tank of fuel and one
person or 160 lbs (75 kg) sitting on the driver seat.
.Have the tires properly inflated.
.Have the spare tire is in its proper location in the
vehicle.
