Speedometer and Odometer
Your speedometer lets you see your speed in
both miles per hour (mph) and kilometers per
hour (km/h). Your odometer shows how far your
vehicle has been driven, in either miles (used
in the United States) or kilometers (used in
Canada).
Your vehicle has a tamper-resistant odometer.
You may wonder what happens if your vehicle
needs a new odometer installed. The new one can
be set to the mileage total of the old odometer.
Trip Odometer
The trip odometer can display how far you have
driven since you last reset it.
For more information seeDIC Operation and
Displays on page 249.
Tachometer
The tachometer displays the engine speed in
revolutions per minute (rpm).
Safety Belt Reminder Light
When the key is turned to RUN or START, a
chime will come on for several seconds to remind
people to fasten their safety belts.
The safety belt light will
also come on and stay
on for several
seconds, then it will
ash for several more.
If the driver remains unbuckled when the ignition
is on and the vehicle is in motion, the chime
and safety belt light will be repeated. You should
buckle your seat belt. If the driver’s belt is
already buckled, neither the chime nor the light
will come on.

Your vehicle has an airbag system. Before
attempting to do your own service work, see
Servicing Your Airbag-Equipped Vehicle on
page 112.
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 552.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your
vehicle can affect the air ow 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
Use of the recommended fuel is an important part
of the proper maintenance of your vehicle. To
help keep your engine clean and maintain optimum
vehicle performance, GM recommends the use
of gasoline advertised as TOP TIER Detergent
Gasoline.
The 8th digit of your Vehicle Identi cation Number
(VIN) shows the code letter or number that
identi es your engine. You will nd the VIN at the
top left of the instrument panel. SeeVehicle
Identi cation Number (VIN) on page 526.
If your vehicle has the 3.9L V6 engine (VIN Code
W only), you may use either regular unleaded
gasoline or ethanol fuel containing up to 85%
ethanol (E85); also seeFuel E85 (85% Ethanol)
on page 431. If your vehicle has the 3.9L V6
engine (VIN Code 1), use only regular unleaded
gasoline.

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 the engine at extremely low temperatures.
Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the starburst symbol meet GM Standard
GM6094M 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 lter.
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 CHANGE OIL SOON message will
come on. SeeDIC Warnings and Messages on
page 256. Change your 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, your engine oil
and lter must be changed at least once a year and
at this time the system must be reset. Your dealer
has GM-trained people who will perform this work
using genuine GM parts and reset the system. It is
also important to check your oil regularly and keep
it at the proper level.
If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5 000 km)
since your last oil change. Remember to reset the
oil life system whenever the oil is changed.
