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
U.S.) or kilometers
(used in Canada).
Tamper-Resistant Odometer
Your odometer
is
tamper-resistant. The odometer will show silver lines
between the numbers if someone tries to turn it back.
You may wonder what happens if your vehicle needs a new odometer
installed. Laws vary as to the procedure that must be followed, so check
with your state or provincial vehicle registration office. But generally, if the
new odometer 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 trip odometer can
tell you how far your
vehicle has been
driven since you last
set the trip odometer
to zero.

To reset the trip odometer, fully press the reset button located near the trip
odometer readout. If the reset button is not fully pressed, the trip odometer
may
not go
all the way back to zero. If it doesn't, you may have to press the
reset button again
to
reset the readout to zero.
