(In this situation, the transmission will operate in the same manner as when the shift
lever is in D.)
■Downshift restriction warning buzzer (S mode)
To help ensure safety and driving perfor mance, downshifting operation may some-
times be restricted. In some circumstances, downshifting may not be possible even
when the shift lever is operated. (A buzzer will sound twice.)

The instrument cluster brightne ss levels when the tail lights are on and off can be
adjusted.

When the tail lights are on, the brightness will change. However, when the sur-
roundings are bright (daytime, etc.) turning on the tail lights will not change the
instrument cluster brightness. 
In addition, the brightness of the instrument cluster lights is automatically adjusted
based on the light sensor detecting how bright the surroundings are.

The trip meter data will be reset. 
If the trip meter was displayed last, the ODO screen will be displayed after reset-
ting.
■Customization
Setting of sensitivity of the ambient light sensor used for dimming the meter lights
can be changed. (Customizable features P. 7 8 1 )
NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which indi-
cates the maximum engine speed.
●The engine may be overheating if the engine coolant temperature gauge is in the
red zone (H). In this case, immediately stop the vehicle in a safe place, and check
the engine after it has cooled completely. ( P. 744)
