or serious injury. Have the vehicle inspected by your Toyota dealer immedi-
ately if this occurs.

■The multi-information display illuminate when
Vehicles without a smart key system:
The engine switch is in the “ON” position.
Vehicles with a smart key system:
The engine switch is in IGNITION ON mode.
■ The brightness of the in strument panel lights
When the tail lights are turned on, the display’s brightness will be reduced
slightly unless the meter brightness level adjustment is set to the brightest
setting.
■ Outside temperature display
●In the following situations, the correct outside temperature ma y not be dis-
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 .
Take your vehicle to your Toyota dealer.
■ Liquid crystal display
Small spots or light spots may appear on the display. This phen omenon is

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 the 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.
NOTICE
■ To prevent damage to the engine and its components
● Do not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
● The engine may be overheating if the engine coolant temperature gauge is
in the red zone (H). In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. ( P. 534)
