CAUTION
■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal informa-
tion 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 shifting 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.
