Tachometer
The tachometer shows engine revolutions per minute. This
allows the driver to determine the most efficient selector posi-
tion and engine speed combinations.
This gauge also assists in evaluating engine performance.

CAUTION
!
The red zone indicates an engine speed beyond the
range of safe operation.
Select the correct shift position (manual transaxle)
or selector position (CVT) to control the engine
speed so that the tachometer indicator does not
enter the red zone.

Rheostat meter illumination button
N00519200263
Each time you press this button, there is a sound and the bright-
ness of the instruments changes.
NOTE
You can adjust to 8 different levels respectively for when
the front side-marker and parking lights are illuminated
and when they are not.
If the vehicle is equipped with the automatic light control,
when the light switch is in a position other than the "OFF"
position, the meter illumination switches automatically to
the adjusted brightness, depending on the brightness out-
side the vehicle.
The brightness level of the instruments is stored when the
ignition switch is turned to the "LOCK" position or the
operation mode is put in OFF.
If you press and hold the button for longer than about 1
second when the front side-marker and parking lights are
illuminated, the brightness level changes to the maximum
level. Pressing and holding the button for longer than
about 1 second again returns the brightness level to the
previous level.
