About the vehicle information screen
• Subjecting the control buttons or liquid crystal display to excessive
shock could result in vehicle information screen deformation or other
damage.
• Keep any heat source (including lighted cigarettes) away from the
vehicle information screen. If a heat source is brought into contact
with the vehicle information system cabinet and panel, they could
be deformed or otherwise degraded.
• In extreme cold, the vehicle information screen may operate slug-
gishly and the display may dim. Such conditions do not indicate a
problem. They will disappear when the cabin temperature rises to a
normal temperature.
• Tiny black and white dots may occasionally appear in the liquid crys-
tal display. These dots are a normal characteristic of the display. They
do not indicate a problem.
• When the vehicle information screen requires cleaning, gently wipe it
with a silicone cloth or other soft cloth. If necessary, spray the cloth
with neutral cleaning fluid. Be sure to wipe away any cleaning fluid
left on the vehicle information screen. Do not spray the cleaning fluid
directly onto the vehicle information screen. Spraying cleaning fluid
directly onto the vehicle information screen could cause an adverse
effect on internal components. It is also not a good idea to wipe the
vehicle information screen with a stiff cloth or attempt to clean it
using thinners, alcohol, or any other volatile solvent. Doing so could
leave scratches and/or erase the control button labels.
• Do not allow the vehicle information screen to get wet. If it gets wet
(allowing, for example, to a spilled drink or wet umbrella), its internal
electronic circuitry may malfunction.
• In hot weather, cool the passenger compartment down before using
the vehicle information system. The liquid crystal display operates
correctly at temperatures between 0°C and 60°C (32°F and 140°F).
When the temperature exceeds 60°C (140°F), the vehicle information
system circuit protection function is activated, causing the display to
dim.
NOTE
• In the interest of safety, the use of some functions may be unavailable while in
driving. The button for a touch screen that cannot be used will be displayed in
tint color (toned down).
• Liquid-crystal displays may be difficult to read when wearing polarized
glasses.
