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 downshifting 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.

■Daytime running light system
●To make your vehicle more visible to other drivers, the parking light turn on
automatically (at a increased intensity) whenever the engine is started and the
parking brake is released. Daytime running lights are not designed for use at

greater durability and consumes less electricity, so it can help improve fuel
economy.
■Headlight control sensor
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.
