Odometer
The odometer shows the total
distance your vehicle has been
driven. It measures miles in U.S.
models and kilometers in Canadian
models. It is illegal under U.S.
federal law and Canadian provincial
regulations to disconnect, reset, or
alter the odometer with the intent to
change the number of miles or
kilometers indicated.

Trip Meter
This meter shows the number of
miles (U.S.) or kilometers (Canada)
driven since you last reset it. There
are two trip meters: Trip A and Trip
B. Each trip meter works
independently, so you can keep track
of two different distances.
Switch between Trip A and Trip B by
pressing the SEL/RESET button.
SEL/RESET BUTTON
To reset a trip meter, display it, then
press and hold the SEL/RESET
button until the number resets to
''0.0''.
