The Instrument Panel: Your Speedometer and Odometer
Information System Your speedometer lets you see your speed in both miles I I“ , _’ .... __ . I, . -’ ~ ” per hour (mph) and kilometers per hour (lun/h). Your
odometer shows how far
your vehicle has been driven,
in either miles (used in the
U.S.) or kilometers (used in
Canada).

Your instrument panel is designed to let’you know at a
glance how your car
is running. You’ll know how fast
you’re going, how much fuel you’re using, and many
other
things you’ll need to know to drive safely and
economically. Your Buick has
a “tamper-resistant odometer.” Your
odometer will read
ERROR if someone has tampered
with it.
You may wonder what happens if your Buick has to
have a new instrument panel cluster installed. The new
odometer doesn’t need to be reset because your car has a
body computer module (BCM) which stores the mileage
in its memory.
If the BCM is changed the chip with the
mileage
is transferred to the new BCM. If the BCM is
damaged and the mileage is lost, then a label on the
driver’s door must show the old reading and when the
new one was installed.
