■Tire pressure
●It may take a few minutes to display the tire inflation pressure after the power switch is
turned to ON mode. It may also take a few minutes to display the tire inflation pressure
after inflation pressure has been adjusted.
●“---” may be displayed if the tire position information cannot be determined due to
unfavorable radio wave conditions.
●Tire inflation pressure changes with temperat ure. The displayed values may also be dif-
ferent from the values measured using a tire pressure gauge.
■Liquid crystal display
Small spots or light spots may appear on the display. This phenomenon is characteristic
of liquid crystal displays, and there is no problem continuing to use the display.
■Customization
Some functions can be customized. ( P. 109, 607)
WARNING
■Caution for use while driving
●When operating the multi-information display while driving, pay extra attention to the
safety of the area around the vehicle.
●Do not look continuously at the multi-info rmation display while driving as you may fail
to see pedestrians, objects on the road, etc. ahead of the vehicle.
■The information display at low temperatures
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 dr iver’s shifting and the new gear number
appearing on the display. This lag could ca use the driver to downshift again, causing
rapid and excessive engine braking and possibly an accident resulting in death or
injury.
■Cautions during setting up the display
As the hybrid system needs to be operating during setting up the display, ensure that
the vehicle is parked in a place with adequa te ventilation. In a closed area such as a
garage, exhaust gases including harmful carbon monoxide (CO) may collect and enter
the vehicle. This may lead to death or a serious health hazard.
NOTICE
■While setting up the display
To prevent 12-volt battery discharge, ensure that the hybrid system is operating while
setting up the display features.
