Speedometer And Odometer - Chevrolet 2008 Impala Owner's Manual

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 in kilometers (used in Canada).
Your vehicle has a tamper-resistant odometer.
If you see ERROR, you'll know someone has
probably tampered with it and the numbers may not
be accurate.
You may wonder what happens if your vehicle needs a
new odometer installed. If the new one can be set to
the mileage total of the old odometer, then that will
be done. But if it can't, then it will be set at zero and a
label must be put on the driver's door to show the
old mileage reading when the new odometer was
installed.
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.
