played, or the display may take longer than normal to change.
• When stopped, or driving at low speeds (less than 12 mph [20 k m/h])
• When the outside temperature has changed suddenly (at the entr ance/
exit of a garage, tunnel, etc.)
● When “--” or “E” is displayed, the system may be malfunctioning .

■ Liquid crystal display
Small spots or light spots may appear on the display. This phen omenon is
characteristic of liquid crystal displays, and there is no prob lem continuing to
use the display.
WARNING
■ 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 driver’s shifting and t he new gear
number appearing on the display. This lag could cause the drive r to down-
shift again, causing rapid and excessive engine braking and pos sibly an
accident resulting in personal death or injury.
