WARNING
■Cautions while 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 adequate 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 oper-
ating while setting up the display features.

In extremely cold environments, the display of the speedometer and the vehi-
cle speed of the head-up display may slightly differ.

The customize settings of the head-up display will be reset.
■ Route guidance display (vehicles with navigation system)
The route guidance is not displayed on both the head-up display and multi-
information display simultaneously. When the route guidance is displayed on
the head-up display, the multi-information display does not display the route
guidance even if the navigation system-linked display ( →P. 133) is selected
