GMC 2012 Canyon Owner's Manual page 118

The speedometer shows the
vehicle's speed in either kilometers
per hour (km/h) or miles per
hour (mph).
The odometer shows how far the
vehicle has been driven, in either
miles (used in the United States) or
kilometers (used in Canada).
The odometer mileage can be
checked without the vehicle running
by pressing the trip information
stem. See Odometer under
for more information.
If the cluster is replaced the new
one will automatically detect and
update the vehicle's accumulated
mileage.
The vehicle has a trip odometer that
indicates how far the vehicle has
been driven since the trip odometer
was last set to zero.
See Trip Odometer under
for more information.
The tachometer displays the engine
speed in revolutions per
minute (rpm).
When the ignition is on, the fuel
gauge shows how much fuel the
vehicle has remaining in the
fuel tank.
An arrow on the fuel gauge
indicates the side of the vehicle
the fuel door is on.
