Speedometer and Odometer
The speedometer lets you see your speed
in both miles per hour (mph) and kilometers
per hour (km/h).
The vehicle’s odometer works together with the
Driver Information Center (DIC), if your vehicle has
one. A Trip A and Trip B odometer can be set.
See “Trip Information” underDIC Operation
and Displays on page 146.
The odometer mileage can be checked without the
vehicle running. Open the driver’s door and the
mileage will be displayed brie y.
If your vehicle ever needs a new odometer
installed, the new one will be set to the correct
mileage total of the old odometer.
Tachometer
The tachometer
displays the engine
speed in revolutions per
minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your
vehicle could be damaged, and the damages
would not be covered by your warranty. Do not
operate the engine with the tachometer in
the shaded warning area.

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.
CAUTION: (Continued)
CAUTION: (Continued)
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 380.
Your vehicle has an airbag system. Before
attempting to do your own service work, see
Servicing Your Airbag-Equipped Vehicle
on page 54.
You should keep a record with all parts receipts
and list the mileage and the date of any service
work you perform. SeePart E: Maintenance
Record on page 357.

Engine Oil Life System
When to Change Engine Oil (Vehicles
With Driver Information Center)
If your vehicle has a Driver Information Center
(DIC), it has the Engine Oil Life System, 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 148. Change the 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 lter 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 your oil regularly and keep it at the
proper level.
If the system is ever reset accidentally, you must
change the oil at 3,000 miles (5 000 km) since
the last oil change. Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to
change your engine oil and lter 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 CHANGE OIL SOON
message being turned on, reset the system.
