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. The
digital odometer will read 999,999 if someone tries to
turn it back.
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 it must
be. But if it can't, then it's 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.

Trip Odometer
The reset button is located next to the trip odometer.
To reset the trip odometer to zero, press and hold
the reset button for one or two seconds. Also, by
pressing this button, you can toggle between the
odometer and the trip odometer.
The trip odometer can
tell you how far you
have driven since you
last reset it.
