If you are locked out of the vehicle, call the Roadside
Assistance Center. SeeRoadside Assistance Program
on page 8‑7.
Remote Keyless Entry (RKE) System
SeeRadio Frequency Statementon page 8‑19for
information regarding Part 15 of the Federal
Communications Commission (FCC) Rules and
RSS-210/211 of Industry and Science Canada.
Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
If there is a decrease in the RKE operating range,
try this:
.Check the distance. The transmitter may be too far
from the vehicle. Stand closer during rainy or
snowy weather.
.Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the left
or right, hold the transmitter higher, and try again.
.Check the transmitter's battery. See “Battery
Replacement” later in this section.
.If the transmitter is still not working correctly, see
your dealer/retailer or a qualified technician for
service.
Remote Keyless Entry (RKE) System
Operation
The Remote Keyless Entry (RKE) transmitter functions
work up to 195 feet (60 m) away from the vehicle.
There are other conditions which can affect the
performance of the transmitter. See Remote Keyless
Entry (RKE) System on page 3‑4.

Starting Procedure
1. With your foot off the accelerator pedal, turn theignition to START. When the engine starts,
let go of the key. The idle speed will slow down
as the engine warms. Do not race the engine
immediately after starting it. Operate the engine
and transmission gently to allow the oil to warm up
and lubricate all moving parts.
The vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine
and protects components. If the ignition key is
turned to the START position, and then released
when the engine begins cranking, the engine will
continue cranking for a few seconds or until the
vehicle starts. If the engine does not start and the
key is held in START, cranking will be stopped
after 15 seconds to prevent cranking motor
damage. To prevent gear damage, this system also
prevents cranking if the engine is already running.
Engine cranking can be stopped by turning the
ignition switch to the ACC/ACCESSORY or
LOCK/OFF position.
Notice: Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheat
and damage the cranking motor, and drain the
battery. Wait at least 15 seconds between each try,
to let the cranking motor cool down. 2. If the engine does not start after 5‐10 seconds,
especially in very cold weather (below 0°F or
−18°C), it could be flooded with too much gasoline.
Try pushing the accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for up to a maximum of 15 seconds. Wait at
least 15 seconds between each try, to allow the
cranking motor to cool down. When the engine
starts, let go of the key and accelerator. If the
vehicle starts briefly but then stops again, repeat
these steps. This clears the extra gasoline from the
engine. Do not race the engine immediately after
starting it. Operate the engine and transmission
gently until the oil warms up and lubricates all
moving parts.
Notice: The engine is designed to work with the
electronics in the vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer/retailer. If you
do not, the engine might not perform properly.
Any resulting damage would not be covered by the
vehicle warranty.

.Make sure to fuel the vehicle with quality fuel.
Poor fuel quality causes the engine not to run
as efficiently as designed and can cause:
stalling after start-up, stalling when the vehicle
is changed into gear, misfiring, hesitation on
acceleration, or stumbling on acceleration.
These conditions might go away once the engine
is warmed up.
If one or more of these conditions occurs, change
the fuel brand used. It will require at least one full
tank of the proper fuel to turn the light off.
SeeGasoline Octane on page 6‑6.
If none of the above have made the light turn off, your
dealer/retailer can check the vehicle. The dealer/retailer
has the proper test equipment and diagnostic tools to fix
any mechanical or electrical problems that might have
developed.Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on the vehicle. Failure to pass this
inspection could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
.The vehicle will not pass this inspection if the
check engine light is on with the engine running,
or if the key is in ON/RUN and the light is not on.
.The vehicle will not pass this inspection if the
OBD II (on-board diagnostic) system determines
that critical emission control systems have not
been completely diagnosed by the system.
The vehicle would be considered not ready for
inspection. This can happen if the battery has
recently been replaced or if the battery has run
down. The diagnostic system is designed to
evaluate critical emission control systems during
normal driving. This can take several days of
routine driving. If this has been done and the
vehicle still does not pass the inspection for lack of
OBD II system readiness, your dealer/retailer can
prepare the vehicle for inspection.

To listen to files by another artist, press the softkey
located below either arrow tab. The disc goes to the
next or previous artist in alphabetical order. Continue
pressing either softkey below the arrow tab until the

player moves to the next album in alphabetical order on
the CD and begins playing MP3 files from that album.
To exit music navigator mode, press the softkey below
the Back tab to return to normal MP3 playback.Connecting a USB Storage Device
or iPod®
The USB Port can be used to control an iPod or a
USB storage device.
To connect a USB storage device, connect the device to
the USB port located on the instrument panel or in the
center console.
To connect an iPod, connect one end of the USB cable
that came with the iPod to the iPod’ s dock connector
and connect the other end to the USB port located in
the center console. If the vehicle is on and the USB
connection works, “OK to disconnect” and a GM logo
may appear on the iPod and iPod appears on the
radio's display. The iPod music appears on the radio’s
display and begins playing.
The iPod charges while it is connected to the vehicle if
the vehicle is in the ACC/ACCESSORY or ON/RUN
position. When the vehicle is turned off, the iPod
automatically powers off and will not charge or draw
power from the vehicle's battery.
If you have an older iPod model that is not supported, it
can still be used by connecting it to the Auxiliary Input
Jack using a standard 3.5 mm (1/8 in) stereo cable.
See “Using the Auxiliary Input Jack” earlier for more
information.
