Driver Information Center (DIC)
If your vehicle is equipped with the Driver Information
Center (DIC), the display is located on the instrument
panel cluster in the tachometer gage. The DIC will show
information about the vehicle and the surroundings.
The DIC is capable of displaying English or French.
To change the language, press and hold the MODE
button until the language you want is displayed.
The MODE button is located on the instrument panel,
to the left of the steering column. Release the button to
set your choice. SeeDIC Controls and Displays on
page 3-62to change the display from English to metric.
The DIC contains a compass display to show you
which direction the vehicle is driving.
Compass Variance
Compass variance is the difference between magnetic
north and geographic north. In some areas of the
country, the difference is great enough to cause the
compass to give false readings. If this occurs, the
compass must be recalibrated. United States

DIC Controls and Displays
When the ignition is turned to ON or START, the DIC
will display the following:
BUICK:BUICK will be displayed for three seconds.
DRIVER #:This message will be displayed for another
three seconds after BUICK appears in the display.
This display lets the driver know which driver’s remote
keyless entry transmitter is being used and the
driver’s customization features.
The DIC controls are
located to the left of the
steering column on
the instrument panel.
The DIC will be in the last mode displayed when the
engine was turned off. To select a different mode, press
MODE. The display will cycle through its options at
each press of MODE.MODE:This button lets you cycle through the options
on the display.
SET:This button is used to select and set the options
to your preference.
The DIC will always display the compass reading and
the outside temperature. If the temperature is below
38°F (3°C), the temperature reading will toggle between
displaying the temperature and the word ICE for
two minutes.
AVG ECONOMY (Average Economy):Average fuel
economy is viewed as a long term approximation of your
overall driving conditions. To learn the average fuel
economy from a new starting point, press and hold
the SET button while the average fuel economy
is displayed on the DIC. The average fuel economy will
set to zero.
INST ECONOMY (Instant Economy):Instant fuel
economy reects the fuel economy that the vehicle
has right now. Instant fuel economy varies with
your driving conditions, such as acceleration, braking
and the grade of the road being traveled. Unlike average
fuel economy, instant fuel economy cannot be reset.

Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is a
mistake. Your brakes may not have time to cool between
hard stops. Your brakes will wear out much faster if you
do a lot of heavy braking. If you keep pace with the traffic
and allow realistic following distances, you will eliminate
a lot of unnecessary braking. That means better braking
and longer brake life.
If your engine ever stops while you are driving, brake
normally but do not pump your brakes. If you do, the
pedal may get harder to push down. If your engine stops,
you will still have some power brake assist. But you will
use it when you brake. Once the power assist is used up,
it may take longer to stop and the brake pedal will be
harder to push.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modications
on page 5-3.Anti-Lock Brake System (ABS)
Your vehicle may have anti-lock brakes. ABS is an
advanced electronic braking system that will help
prevent a braking skid.
If your vehicle has anti-lock brakes, this warning light on
the instrument panel will come on briey when you
start your vehicle.
When you start your engine, or when you begin to drive
away, your anti-lock brake system will check itself.
You may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that
your brake pedal moves or pulses a little. This is normal.United States

If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
reengage the cruise control. SeeCruise Control
on page 3-10.
If this message comes on and stays on or comes on
while you are driving, there’s a problem with your
traction control system.
SeeService Traction System Warning Message on
page 3-51. When this warning message is on, the TRAC
OFF light will come on to remind you that the system
will not limit wheel spin. Adjust your driving accordingly.The traction control system automatically comes on
whenever you start your vehicle. To limit wheel
spin, especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system off if you ever need to. You
should turn the system off if your vehicle ever gets stuck
in sand, mud or snow and rocking the vehicle is
required. SeeIf Your Vehicle is Stuck in Sand, Mud,
Ice or Snow on page 4-30.
To turn the system off, press the TRAC OFF button
located on the instrument panel switchbank.
If the system is limiting wheel spin when you press the
button, the message will go off, but the system will
not turn off until there is no longer a current need to limit
wheel spin. The TRAC OFF light will come on to
remind you the system is off. You can turn the system
back on at any time by pressing the button again.
The traction control system warning message should
go off.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modications
on page 5-3for more information. United States

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have
extra wiring.
The arrows on your instrument panel will ash whenever
you signal a turn or lane change. Properly hooked up,
the trailer lamps will also ash, telling other drivers
you are about to turn, change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will ash for turns even if the bulbs on the
trailer are burned out. Thus, you may think drivers
behind you are seeing your signal when they are not.
It is important to check occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you do not shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
If you are towing a trailer that weighs more than 1,000 lbs
(450 kg), drive in AUTOMATIC OVERDRIVE (D) or,
as you need to, a lower gear. This will minimize heat
build-up and extend the life of your transaxle.
Parking on Hills
{CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People
can be injured, and both your vehicle and the
trailer can be damaged.
But if you ever have to park your rig on a hill, do the
following:
1. Apply your regular brakes, but do not shift into
PARK (P) yet.
2. Have someone place chocks under the trailer
wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your
parking brake, and then shift to PARK (P).
5. Release the regular brakes.

Doing Your Own Service Work
{CAUTION:
You can be injured and your vehicle could be
damaged if you try to do service work on a
vehicle without knowing enough about it.
Be sure you have sufficient knowledge,
experience, the proper replacement parts,
and tools before you attempt any vehicle
maintenance task.
Be sure to use the proper nuts, bolts,
and other fasteners. English and metric
fasteners can be easily confused. If you
use the wrong fasteners, parts can later
break or fall off. You could be hurt.
If you want to do some of your own service work,
you will want to use the proper service manual. It tells
you much more about how to service your vehicle
than this manual can. To order the proper service
manual, seeService Publications Ordering Information
on page 7-14.Your vehicle has an airbag system. Before attempting
to do your own service work, seeServicing Your
Airbag-Equipped Vehicle on page 1-85.
You should keep a record with all parts receipts and
list the mileage and the date of any service work
you perform. SeeMaintenance Record on page 6-14.
Adding Equipment to the Outside
of Your Vehicle
Things you might add to the outside of your vehicle
can affect the airow around it. This may cause
wind noise and affect windshield washer performance.
Check with your dealer before adding equipment to
the outside of your vehicle.
Fuel
The 8th digit of your vehicle identication number (VIN)
shows the code letter or number that identies your
engine. You will nd the VIN at the top left of the
instrument panel. SeeVehicle Identication
Number (VIN) on page 5-99.

Checking Things Under
the Hood
{CAUTION:
An electric fan under the hood can start up
and injure you even when the engine is not
running. Keep hands, clothing and tools away
from any underhood electric fan.
{CAUTION:
Things that burn can get on hot engine parts
and start a re. These include liquids like fuel,
oil, coolant, brake uid, windshield washer
and other uids, and plastic or rubber. You or
others could be burned. Be careful not to drop
or spill things that will burn onto a hot engine.
Hood Release
To open the hood, do the following:
1. Pull the hood release
handle with this symbol
on it. It is located
under the instrument
panel on the driver’s
side of the vehicle.
2. At the front of the vehicle, pull up on the center
of the hood, and push the secondary hood
release to the right.
3. After you have partially lifted the hood, gas struts
will automatically take over to lift and hold the
hood in the fully open position.
Before closing the hood, be sure all ller caps are
on properly. Then, pull the hood down to close.
5-9

Adding Coolant
If you need more coolant, add the proper DEX-COOL®
coolant mixture at the coolant recovery tank, but be
careful not to spill it.
{CAUTION:
Turning the radiator pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
With the coolant recovery tank, you will almost
never have to add coolant at the radiator.
Never turn the radiator pressure cap — even a
little — when the engine and radiator are hot.
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.Occasionally check the coolant level in the radiator.
For information on how to add coolant to the radiator,
seeCooling System on page 5-26.
Radiator Pressure Cap
Notice:The radiator cap on your vehicle is a
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating. Be sure the arrows on the cap line
up with the overow tube on the radiator ller neck.
The radiator pressure cap for the 3.5L V6 engine and
the 3.6L V6 engine are located in different areas of
the engine compartment. SeeEngine Compartment
Overview on page 5-10for more information on location.
Engine Overheating
You will nd a coolant temperature warning and a
coolant temperature gage on your vehicle’s instrument
panel. SeeEngine Coolant Temperature Warning
Message on page 3-52andEngine Coolant
Temperature Gage on page 3-46.
If your vehicle is equipped with the 3.6L V6 engine,
you will also have a reduced engine power message.
SeeReduced Engine Power Message on page 3-53.
5-23

If any of the soil remains, a commercial fabric cleaner
or spot lifter may be necessary. When a commercial
upholstery cleaner or spot lifter is to be used, test
a small hidden area for colorfastness rst. If the locally
cleaned area gives any impression that a ring
formation may result, clean the entire surface.
After the cleaning process has been completed, a paper
towel can be used to blot excess moisture from the
fabric or carpet.
Leather
A soft cloth dampened with water may be used to
remove dust. If a more thorough cleaning is necessary,
a soft cloth dampened with a mild soap solution can
be used. Allow the leather to dry naturally. Do not use
heat to dry. Never use steam to clean leather. Never
use spot lifters or spot removers on leather. Many
commercial leather cleaners and coatings that are sold
to preserve and protect leather may permanently
change the appearance and feel of your leather and are
not recommended. Do not use silicone or wax-based
products, or those containing organic solvents to clean
your vehicle’s interior because they can alter the
appearance by increasing the gloss in a non-uniform
manner. Never use shoe polish on your leather.
Instrument Panel, Vinyl, and Other
Plastic Surfaces
A soft cloth dampened with water may be used to
remove dust. If a more thorough cleaning is necessary,
a clean soft cloth dampened with a mild soap solution
can be used to gently remove dust and dirt. Never use
spot lifters or removers on plastic surfaces. Many
commercial cleaners and coatings that are sold to
preserve and protect soft plastic surfaces may
permanently change the appearance and feel of your
interior and are not recommended. Do not use silicone
or wax-based products, or those containing organic
solvents to clean your vehicle’s interior because
they can alter the appearance by increasing the gloss
in a non-uniform manner.
Some commercial products may increase gloss on your
instrument panel. The increase in gloss may cause
annoying reections in the windshield and even make
it difficult to see through the windshield under certain
conditions.
