(vehicles with an automatic transmission only)
Indicates the current gear, and the range of gears
that is available when the shift lever is in the D
or S position. The gear range is shown by the
number of dots () and the current gear is shown
as a number. The transmission automatically
selects the gears within the driver selected gear
range.
In the illustration to the left, a range of 6 available
gears (1 through 6) has been selected by the driver.
(The shift lever is in the D or S position with 6
ranges enabled.) It is possible for the transmission
to automatically select between all 6 of the gears.
In this case, the transmission has selected third

CAUTION
When the temperature of the display is extremely low
Allow the interior of the vehicle to warm up before using the liquid crystal
information display. At extremely low temperatures, the information display
monitor may respond slowly, and display changes may be delayed.
For example, there is a lag between the driver’s downshifting and the new
gear number appearing on the display. In this case, wait until the display
changes and take care not to downshift again, causing rapid and excessive
engine braking and possibly an accident resulting in death or serious injury.

the windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction
