Vehicle Data
Average Fuel Economy:Press the SELECT button
until the display shows AVG FUEL 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 the
RESET button for ve seconds while the average fuel
economy is displayed on the DIC.
Instantaneous Fuel Economy:Press the SELECT
button until the display shows INST FUEL ECONOMY.
Instantaneous fuel economy varies with your driving
conditions, such as acceleration, braking and the grade
of the road being traveled. The RESET button does
not function in this mode.
Fuel Range:Press the SELECT button until the display
shows FUEL RANGE. The fuel range will calculate
the remaining distance you can drive without refueling.
This calculation is based on the average fuel economy
for the last 25 miles (40.25 km) driven and the fuelremaining in the fuel tank. If the fuel range drops below
40 miles (64.4 km), the display will show FUEL
RANGE LOW. The RESET button does not function in
this mode.
Fuel Used:Press the SELECT button until the display
shows FUEL USED. The value indicates how much
fuel has been used since the last reset. Do not confuse
fuel used with the amount of fuel in your tank. To
learn how much fuel will be used from a specic starting
point, press the RESET button for ve seconds while
the fuel used is displayed on the DIC.
Engine Oil Life System:Press the SELECT button
until OIL LIFE appears in the display. The OIL LIFE
NORMAL display will show an estimate of the oil’s
remaining useful life. When the oil life index is less than
10%, an ENGINE OIL CHANGE SOON message will
be displayed and the oil life display will show OIL LIFE
CHANGE. When the ENGINE OIL CHANGE SOON
message is displayed, it means that service is required
for your vehicle. See your GM dealer.
In addition to the engine oil life system monitoring the
oil life, additional maintenance is recommended in
the Maintenance Schedule in this manual. SeePart A:
Scheduled Maintenance Services on page 6-4and
Engine Oil on page 5-16for more information.

The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted. Reduce your speed
according to your speedometer, not to your sense
of motion. After driving for any distance at higher
speeds, you may tend to think you are going slower
than you actually are.
Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested. If you
must start when you are not fresh — such as after
a day’s work — do not plan to make too many miles that
rst part of the journey. Wear comfortable clothing
and shoes you can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it needs
service, have it done before starting out. Of course, you
will nd experienced and able service experts in GM
dealerships all across North America. They will be ready
and willing to help if you need it.Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir full? Are
all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you checked
all levels?
Lamps:Are they all working? Are the lenses clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inated to the
recommended pressure?
Weather Forecasts:What is the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
Maps:Do you have up-to-date maps?

Notice:Your vehicle was not designed for fuel that
contains methanol. Do not use fuel containing
methanol. It can corrode metal parts in your fuel
system and also damage the plastic and rubber
parts. That damage would not be covered under
your warranty.
Some gasolines that are not reformulated for low
emissions may contain an octane-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask the attendant where you buy gasoline
whether the fuel contains MMT. General Motors does
not recommend the use of such gasolines. Fuels
containing MMT can reduce the life of spark plugs and
the performance of the emission control system may
be affected. The malfunction indicator lamp may turn on.
If this occurs, return to your authorized GM dealer
for service.Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard
to nd. Never use leaded gasoline or any other fuel
not recommended in the previous text on fuel. Costly
repairs caused by use of improper fuel would not
be covered by your warranty.
To check the fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you will be driving.

SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is best
for your vehicle.
These numbers on an oil container show its
viscosity, or thickness. Do not use other viscosity
oils such as SAE 20W-50.
Oils meeting these
requirements should also
have the starburst
symbol on the container.
This symbol indicates
that the oil has been
certied by the American
Petroleum Institute (API).
You should look for this information on the oil container,
and useonlythose oils that are identied as meeting
GM Standard GM6094M and have the starburst symbol
on the front of the oil container.Notice:Use only engine oil identied as meeting
GM Standard GM6094M and showing the American
Petroleum Institute Certied For Gasoline Engines
starburst symbol. Failure to use the recommended
oil can result in engine damage not covered by
your warranty.
GM Goodwrench
®oil meets all the requirements for
your vehicle.
If you are in an area of extreme cold, where the
temperature falls below−20°F (−29°C) it is
recommended that you use either an SAE 5W-30
synthetic oil or an SAE 0W-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.
Engine Oil Additives
Do not add anything to your oil. The recommended oils
with the starburst symbol that meet GM Standard
GM6094M are all you will need for good performance
and engine protection.

How to Add Fluid
Refer to the Maintenance Schedule to determine
what kind of transaxle uid to use. SeePart D:
Recommended Fluids and Lubricants on page 6-24.
If the uid level is low, add only enough of the proper
uid to bring the level into the cross-hatched area
on the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough uid at the
dipstick hole to bring it to the proper level.
It does not take much uid, generally less than
one pint (0.5 L).Do not overll.
Notice:Use of automatic transaxle uid labeled
other than DEXRON
®-III, Approved for the
H-Specication, may damage your vehicle, and the
damages may not be covered by your warranty.
Always use automatic transaxle uid labeled
DEXRON
®-III, Approved for the H-Specication.
3. After adding uid, recheck the uid level as
described under “How to Check,” earlier in
this section.
4. When the correct uid level is obtained, push the
dipstick back in all the way.
Automatic Transaxle Fluid
(4.6L V8 Engine)
When to Check and Change
A good time to check your automatic transaxle uid
level is when the engine oil is changed.
Change both the uid and lter every 50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police or
delivery service.
Use such as limousine service.
If you do not use your vehicle under any of these
conditions, change the uid and lter at 100,000 miles
(166 000 km).

Engine Coolant (3.8L V6 Engine)
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs rst, if you add
only extended life coolant.
The following explains your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, seeEngine Overheating
(3.8L V6 Engine) on page 5-36orEngine Overheating
(4.6L V8 Engine) on page 5-38.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Give freezing protection down to−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
Notice:Using coolant other than DEX-COOL
®may
cause premature engine, heater core or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at 30,000 miles (50 000 km)
or 24 months, whichever occurs rst. Any repairs
would not be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your vehicle.

How to Add Coolant to the Coolant
Recovery Tank
If you have not found a problem yet, but the coolant
level is not at the FULL COLD mark, add a
50/50 mixture ofclean, drinkable waterand DEX-COOL
®
engine coolant at the coolant recovery tank. SeeEngine
Coolant (3.8L V6 Engine) on page 5-31orEngine
Coolant (4.6L V8 Engine) on page 5-34for more
information.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle’s coolant warning system is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you would not get the overheat warning.
Your engine could catch re and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.Notice:In cold weather, water can freeze and crack
the engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.
{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.
When the coolant in the coolant recovery tank is at the
FULL COLD mark, start your vehicle.

What to Add
When you do need brake uid, use only DOT-3 brake
uid. Use new brake uid from a sealed container
only. SeePart D: Recommended Fluids and Lubricants
on page 6-24.
Always clean the brake uid reservoir cap and the area
around the cap before removing it. This will help
keep dirt from entering the reservoir.
{CAUTION:
With the wrong kind of uid in your brake
system, your brakes may not work well, or
they may not even work at all. This could
cause a crash. Always use the proper
brake uid.Notice:
Using the wrong uid can badly damage brake
system parts. For example, just a few drops of
mineral-based oil, such as engine oil, in your
brake system can damage brake system
parts so badly that they will have to be
replaced. Do not let someone put in the
wrong kind of uid.
If you spill brake uid on your vehicle’s painted
surfaces, the paint nish can be damaged.
Be careful not to spill brake uid on your
vehicle. If you do, wash it off immediately.
