Trip Computer
The buttons for the trip
computer are located to
the right of the gages and
the display is located
directly beneath the gages.
The basic, more commonly used functions of the trip
computer are shown following. Tap the MODE button to
scroll between the different sets of display.
You will notice that speed related displays are in the left
window, distance related displays in the center, and
fuel related windows on the right.
When the ignition is turned on, the trip computer
displays the same functions as when the ignition was
last turned off.The trip computer can be reset when AVG SPEED or
TRIP TIME are shown on the left window. To reset,
press the SET button for less than two seconds.
Resetting does not affect the Odometer, Overspeed,
Distance to Empty, Time to Arrival, Distance to Arrival,
Instantaneous Fuel, or Remaining Fuel.
Vehicle personalization is available through the trip
computer controls and display. SeeVehicle
Personalization on page 2-32.
AVG SPEED
This function shows the average speed, while the
engine is running, since the trip computer was reset.
Odometer
This function records miles travelled since the car
was built.
AVG FUEL
This function shows average fuel used since the trip
computer was reset. After resetting, a high number may
initially be shown, due to the short distance travelled
and the high fuel used when accelerating.

Altering Overspeed Presets
The default overspeed settings can be changed for your
individual preference.
The car must be standing still when changing a preset.
Ensure the preset you wish to change is showing.
Then briefly press the SET button. The display starts to
flash. Use the up or down arrows to adjust the setting.
When correct, 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 standing still) 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 standing still, overspeed is turned
completely off or on.
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.
To start/stop the stop watch, press SET to reset it, then
press and hold MODE for more than three seconds.
The trip computer must be on Trip Time for this function
to work.
DIGITAL SPEEDO
If digital speedo mode is activated, the mph (km/h) are
shown in a large digital mode.
Rest Reminder
This feature alerts you when you may have been
travelling for too long without a break. After the ignition
is turned on, a timer will start, and after two hours of
continuous driving, the trip computer automatically
shows the rest reminder display. The default on this
feature is off.

Trip A/B
When the Time to Arrival/Distance to Arrival/Fuel
Remaining set of windows 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 (labeled 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/Remaining Fuel 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 2-32. 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 window to show a display other
than normal, turn the ignition off then on again
when the vehicle is standing still.
•Several warning lights are linked to the trip
computer displays. SeeWarning Lights, Gages, and
Indicators on page 3-23.
•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 required. 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.
•If the X symbol or a Service Error message is
shown in the display, it indicates a fault in the
trip computer and you should see your vehicle
dealer.

Master Reset
Your radio has a reset feature that allows you to return
certain settings back to the factory default settings.
Use this feature when adjustments have been made that
affect the sound quality or operation of the radio and
you are unsure of how to return to the original settings.
This master reset feature will reset the following:
•Bass, Treble, Fade, and Balance
•Confirmation beeps to on
•SDV to setting 2
•DDL to on
•EQ to off.
To perform the master reset, do the following:
1. Turn off the radio by pressing the OFF button.
2. Press the ON button and pushbutton 4 at the same
time for about two seconds.
After the radio has finished resetting, the radio will

Mobile Telephone
Your radio includes a telephone adapter. The phone
adapter and the radio are connected. If a mobile phone
hands-free kit with the correct features, such as mute
line and wiring for a separate speaker has been
connected to it, the sound of the radio or CD will be
muted when the phone rings, the voice of the caller will
then be heard through the vehicle’s speakers, and
VOICE ON will appear on the display. When the call
ends, the radio or CD will come back on.
If the radio is off, it will turn on for a phone call if the
vehicle’s ignition is in ON or ACCESSORY.
If a call is in progress when the vehicle is turned off, the
radio will remain on until the call is completed.
You can adjust the volume, bass, treble, fade, and
balance when a phone call is in progress without
affecting the radio settings.

Theft-Deterrent Feature
Your radio has an electronically coded security system.
The system recognizes the vehicle which your 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 4-digit PIN
code to be entered.
The PIN is supplied on your 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 your glovebox. The PIN should also
be written down and kept with other important
documents.
If your security card is lost and the PIN is not recorded,
the PIN can be requested from your 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 your radio is armed.
Security Release Procedure
To type in your PIN code, do the following:
1. Turn the ignition to ACCESSORY.
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.
3-52

Using Anti-Lock
Do not pump the brakes. Just hold the brake pedal
down firmly and let anti-lock work for you. You may hear
the anti-lock pump or motor operate, and feel the
brake pedal pulsate, but this is normal.
Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.
Traction Control System (TCS)
Your vehicle has a Traction Control System (TCS) that
limits wheel spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that one or both of the rear wheels are spinning or
beginning to lose traction. When this happens,
the system reduces engine power and applies the
brakes, as necessary.
Traction control helps you to keep control of the vehicle
and reminds you to match your speed to the road
conditions. In addition, traction control when activated,
provides feedback to the driver by pulsing the
accelerator pedal.You may feel or hear the system working, but this is
normal. The TCS is automatically turned on whenever
the ignition is turned from off to on. A Low Traction
message is displayed on the trip computer, indicating
traction control is limiting wheel spin, until the MODE
button on the trip computer is pressed. The message
then goes back to the original trip computer display with
a small low traction symbol on the left. The symbol
will remain as long as the low traction situation exists.
To limit wheel spin, especially in slippery road
conditions, you should always leave the TCS on.
But you can turn the system off if you prefer.
To turn the system off,
press the T/C button.
On manual transmission
vehicles the button is
located on the driver’s side
of the center console.
On automatic transmission
vehicles the button is
located on the passenger’s
side of the shift lever.
4-8

When you turn the system off, a Traction Ctrl Off
message is displayed on the trip computer. After
two seconds, the display goes back to the original
trip computer display with a small TRAC OFF icon
on the right.
If the Traction Ctrl Off message does not display when
the button is pressed, or if it comes on during driving,
a problem is indicated in the system and traction control
is no longer operational. You should contact your
dealer for service.
Pressing the T/C button again or the next time the
ignition is turned on, will turn the system back on.
The Traction Ctrl On message is displayed on the trip
computer. After two seconds, the display goes back
to the original trip computer display.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
Steering Tips
Driving on Curves
It is important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here is why:
Experienced driver or beginner, each of us is subject to
the same laws of physics when driving on curves.
The traction of the tires against the road surface makes
it possible for the vehicle to change its path when
you turn the front wheels. If there is no traction, inertia
will keep the vehicle going in the same direction. If
you have ever tried to steer a vehicle on wet ice, you
will understand this.
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.
4-9

If you drive regularly in steep country, or if you are
planning to visit there, here are some tips that can make
your trips safer and more enjoyable.
•Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system
and transmission. These parts can work hard
on mountain roads.
•Know how to go down hills. The most important
thing to know is this: let your engine do some of
the slowing down. Shift to a lower gear when you go
down a steep or long hill.
{CAUTION:
If you do not shift down, your brakes could get
so hot that they would not work well. You
would then have poor braking or even none
going down a hill. You could crash. Shift down
to let your engine assist your brakes on a
steep downhill slope.
{CAUTION:
Coasting downhill in NEUTRAL (N) or with the
ignition off is dangerous. Your brakes will have
to do all the work of slowing down. They could
get so hot that they would not work well. You
would then have poor braking or even none
going down a hill. You could crash. Always
have your engine running and your vehicle in
gear when you go downhill.
•Know how to go uphill. You may want to shift down
to a lower gear. The lower gears help cool your
engine and transmission, and you can climb the
hill better.
•Stay in your own lane when driving on two-lane
roads in hills or mountains. Do not swing wide
or cut across the center of the road. Drive at speeds
that let you stay in your own lane.
•As you go over the top of a hill, be alert. There
could be something in your lane, like a stalled car or
an accident.
•You may see highway signs on mountains that
warn of special problems. Examples are long
grades, passing or no-passing zones, a falling rocks
area or winding roads. Be alert to these and take
appropriate action.

How to Reset the Service Engine Oil
message
The GM Oil Life System calculates when to change
your engine oil and filter based on vehicle use. Anytime
your oil is changed, reset the system so it can
calculate when the next oil change is required. If a
situation occurs where you change your oil prior to a
Service Engine Oil message being turned on, reset the
system.
After changing the engine oil, reset the system by
performing the following steps:
1. With the engine off, turn the ignition key to ON.
2. Fully press and release the accelerator pedal slowly
two times within five seconds.
3. Turn the key to LOCK.
If the Service Engine Oil message comes back on
when you start your vehicle, the engine oil life
system has not reset. Repeat the procedure.
What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Do not let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a good
hand cleaner. Wash or properly dispose of clothing or
rags containing used engine oil. See the manufacturer’s
warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from the
filter before disposal. Never dispose of oil by putting it
in the trash, pouring it on the ground, into sewers, or into
streams or bodies of water. Instead, recycle it by
taking it to a place that collects used oil. If you have a
problem properly disposing of your used oil, ask
your dealer, a service station or a local recycling center
for help.
