O/SPEED (Overspeed)
Overspeed sets the speed you do not want to exceed.
For example, if driving in a 45 mph zone, set
OVERSPEED to 45 mph by tapping the up or down
arrows. The overspeed setting is shown in the left
display. When your vehicle’s speed exceeds the setting,
the overspeed warning message and an audible
chime warn you that you are speeding. At that time,
the trip computer automatically shows the overspeed
display, allowing you to make adjustments if desired.
If in the Overspeed preset mode, press and hold
the MODE button for two seconds to make adjustments.
Preset O/Speed (Overspeed)
Instead of adjusting overspeed up and down in
increments of 3 mph (5 km/h), you can set
four commonly used speeds. Hold down the MODE
button for two seconds when the overspeed display is
shown. The display changes from normal overspeed
operation to preset overspeed. Preset 1 has a default
setting of 25 mph (40 km/h). Tap the up arrow to see the
other three presets.
The overspeed preset display has now replaced the
normal overspeed display. Tap the MODE button
to scroll through the other displays.
To change the display back to normal overspeed, hold
down the MODE button for two seconds while the
overspeed preset display is shown.
Altering Overspeed Presets
The default overspeed settings can be changed for your
individual preference.
The vehicle must be stopped when changing a preset.
Ensure the preset you wish to change is showing.
Then briefly press the SET button. The display will start
to flash. Use the up or down arrows to adjust the
setting. When at the desired speed, briefly press the
SET button. Each PRESET can be changed in this way.
The presets are automatically arranged in
ascending order.
One or more presets can be assigned to OFF, by
reducing the preset down to 0 (OFF). When driving, you
then only have three or less presets to choose from.
To turn back on, select the OFF preset when the vehicle
is stopped, briefly press the SET button, and use the
up arrow to increase the number.
If the up or down arrows are briefly pressed while
driving, the overspeed setting is changed to the speed
at which you are travelling.
If the SET button is pressed for two seconds, either
while driving or stopped, overspeed is turned completely
off or on.

Underspeed Chime
Overspeed provides a chime when your vehicle’s
travelling speed exceeds the overspeed value, whereas
underspeed provides a chime to indicate when your
vehicle’s travelling speed drops below the overspeed.
Range
Range is an estimate of how far your current fuel level
will last. It is based on your previous fuel usage and is
frequently updated. Therefore, as conditions become
suited to more economical driving, the range may actually
increase, for example from city to highway driving.
INST (Instantaneous) FUEL
This function shows instantaneous fuel usage in miles
per gallon or liters per 100 km when driving. When
speed drops below 6 mph (10 km/h) the usage is shown
in gallons per hour or liters per hour.
Display Units
Display units allows you to select the units of
measurement in which the trip computer and instrument
panel cluster will display information. Tap the up or
down arrows to select between ENG (English) or
MET (metric) units.
DIGITAL SPEEDO (Speedometer)
If digital speedo mode is activated, the mph (km/h) are
shown in a large digital mode.
Stop Watch
The stop watch function, when enabled, records
elapsed time. It can be used, for example, to measure
the time taken to travel between two points on a
trip. If you will be starting and stopping your vehicle, the
stop watch will automatically start timing where it left
off when you last stopped.
To start or stop the stop watch, press the SET button.
To reset the stop watch, press and hold the MODE
button for more than three seconds. The trip computer
must be on Trip Time for this function to work.

Trip A/B
When the Time to Arrival/Distance to Arrival/Fuel
Remaining set of displays are turned on, using vehicle
personalization, and are showing on the display,
hold the MODE button down for two seconds. Now,
instead of the Time to Arrival set of displays, the
trip computer shows Trip B details.
Press the MODE button to view your displays. You now
have two different sets of trip displays counting, your
original set of trip displays — labelled A while B is
turned on — and a new set of trip displays, labelled B.
This is useful on a long trip, as Trip B can be reset
at the beginning of the journey and then locked away
by pressing the MODE button for two seconds when
Trip B is shown. Time to Arrival/Distance to Arrival/Fuel
Remaining will again be shown on the display, but
Trip B is still counting away in the background and the
original trip display can be used for short distances
during the journey. Trip B can be viewed at any time by
pressing the MODE button for two seconds when
Distance to Arrival is shown.
Trip A/B can also be enabled/disabled in vehicle
personalization. SeeVehicle Personalization on
page 2-30. If the Trip A and B function is selected,
the Average Speed and Average Fuel displays
indicate Trip A.
Trip Computer Notes:
•If the wrong buttons are accidentally pressed,
causing the display to show a display other
than normal, turn the ignition off and then on again
when the vehicle is stopped.
•Several warning lights are linked to the trip
computer displays. SeeWarning Lights, Gages, and
Indicators on page 3-22.
•When the overspeed warning symbol is first shown,
the overspeed trip computer display is automatically
shown for 10 seconds. This is to show what your
pre-selected speed is and allow you to adjust
it if desired. After 10 seconds, the trip computer
returns to its previous display.
•Some displays change the units of measurement
over time. For example, the Time to Arrival shows
hours only above 99 hours and 59 minutes, and
hours and minutes below. Time to Arrival also
shows 10 minute units above 2 hours, 5 minute
units below 2 hours and 1 minute units below
10 minutes.

CD Messages
CD ERROR PLAY:The CD cannot be read. The CD is
dirty, scratched, wet, or upside down.
CD ERROR MECH (Mechanism):If this message
appears on the display, it could be for one of the
following reasons:
•The CD is stuck in the player and cannot be
played, loaded, or ejected.
•It is very hot. When the temperature returns to
normal, the CD should play.
•You are driving on a very rough road. When the
road becomes smoother, the CD should play.
•The air is very humid. If so, wait about an hour and
try again.
•There may have been a problem while burning
the CD.
•The label may be caught in the CD player.
If the CD is not playing correctly, for any other reason,
try a known good CD.
If any error occurs repeatedly or if an error cannot be
corrected, contact your dealer. If the radio displays
an error message, write it down and provide it to your
dealer when reporting the problem.
Options Menu
The following features can be adjusted through the
vehicle’s options menu located in the instrument panel
cluster in the trip computer display window.
Conrmation Beeps
Beeps are used to confirm various actions of the radio
such as storing a preset. The beeps can be turned
on or off using the options menu. See “Options Menu
Adjustment” later in this section to adjust the
confirmation beeps.
BEEPS ON:The radio will make a beep sound when
storing radio stations, when it is time to insert or remove
a CD from the CD changer, or to confirm that the
LOAD ALL or EJECT ALL functions have started.
BEEP ONLY:The radio will make a beep sound when
it is time to insert or remove a CD from the CD
changer or to confirm that the LOAD ALL or EJECT ALL
functions have started.
BEEPS OFF:The radio will not produce any beeps.
3-52

Speed-Dependent Volume (SDV)
With SDV, the audio system adjusts automatically to
make up for road or wind noise as you drive.
This feature will never completely compensate for
driving noise. There are other factors such as road
surface, wind noise, windows open, and engine speed
that may alter the interior noise for any given road
speed.
You can select compensation rates between 0 (off)
and 5 (maximum compensation) in the options menu.
See “Options Menu Adjustment” later in this section
to adjust SDV.
Dynamic Distortion Limiting (DDL)
The radio has a feature that limits the amount of
amplifier distortion that you can hear. When this feature
is turned on, it continuously monitors the quality of
the signal to the speakers. When the signal distortion
exceeds the preset limits the radio will automatically limit
or reduce the volume until the distortion is minimized.
Under some circumstances, distortion may be heard for
a very short period of time until the system has taken
the necessary steps to limit it.The speakers may go off when the volume level is set
at a high or full volume for a long period of time in order
to protect the amplifier from overheating. When the
amplifier cools down, the radio will reset and you will
again hear sound through the speakers.
The main source of distortion in music is the low
frequency bass caused by drums or large instruments.
Music that features very strong bass may trigger the
distortion limiting system and the system will then
reduce the volume to minimize the distortion. Increasing
the bass control or the EQ boost may also result in a
reduced volume level due to the emphasized bass. See
“Setting the Tone (Bass/Treble)” previously in this
section. The DDL can be turned off so that the radio will
deliver a higher volume level, but distortion will also
be increased.
See “Options Menu Adjustment” later in this section to
adjust DDL.

Theft-Deterrent Feature
Your vehicle’s radio has an electronically coded security
system. The system recognizes the vehicle which the
radio has been installed. If the radio is kept in the
vehicle, the PIN should not be required, even if the
battery or the radio has been removed and reinstalled.
If the link between your vehicle and the radio is
disrupted, the radio will prompt you for a four-digit
PIN code to be entered.
The PIN is supplied on the security card. As the pin is
the only means of enabling operation of the radio, place
the security card in a safe place. Do not leave the
security card in the glovebox. The PIN should also be
written down and kept with other important documents.
If the security card is lost and the PIN is not recorded,
the PIN can be requested from your GM dealer,
after supplying proof of ownership. There may be a
charge for this service.
When the radio and vehicle are turned off, the blinking
red light indicates that the radio is armed.
Security Release Procedure
To type in the PIN code, do the following:
1. Turn the ignition to ON.
2. Turn the radio on. CODE____will appear on
the display.
3. Use the preset buttons to enter the PIN code.
If the wrong PIN code is entered, the radio will display
CODE ERR WAIT.
After a few seconds, the radio will display
CODE 2____,indicating that this is the
second attempt. The correct code should now
be entered. After three attempts, the radio will
display LOCK OUT 1 HR. After 1 hour, the radio will
allow another three attempts to enter the PIN.
3-55

Your vehicle’s engine is filled at the factory with a
Mobil 1®synthetic oil, which meets all requirements
for your vehicle.
Substitute Engine Oil: When adding oil to maintain
engine oil level, oil meeting GM Standard GM4718M
may not be available. You can add substitute oil
designated SAE 5W-30 with the starburst symbol at all
temperatures. Substitute oil not meeting GM Standard
GM4718M should not be used for an oil change.
Engine Oil Additives
Do not add anything to the oil. The recommended oils
with the starburst symbol that meet GM Standard
GM4718M are all you will need for good performance
and engine protection.
Engine Oil Life System
When to Change Engine Oil
Your vehicle has a computer system that lets you know
when to change the engine oil and filter. This is
based on engine revolutions and engine temperature,
and not on mileage. Based on driving conditions,
the mileage at which an oil change will be indicated can
vary considerably. For the oil life system to work
properly, you must reset the system every time the oil is
changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. A Service Engine Oil light on the trip
computer display will come on. SeeTrip Computer on
page 3-33. Change engine oil as soon as possible within
the next 600 miles (1 000 km). It is possible that, if
you are driving under the best conditions, the oil
life system may not indicate that an oil change is
necessary for over a year. However, the engine oil and
filter must be changed at least once a year and at
this time the system must be reset. Your dealer has
GM-trained service people who will perform this
work using genuine GM parts and reset the system. It is
also important to check engine oil regularly and keep
it at the proper level.
