Changing units for the digital speedometer (right-hand drive vehicles only)
Units for the digital speedometer can be changed between km/h and mph by
pushing and holding the odometer/trip meter reset button while the odome-
ter is displayed. At this time, all the units for the multi-information display

CAUTION
When the temperature of the display is extremely low
Allow the interior of the vehicle to warm up before using the shift position
and shift range/gear display. At extremely low temperatures, the display
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.
