The brightness of the instrument panel lights
When the tail lights are turned on, the meter’s brightness will be re duced slightly unless
the meter brightness leve l adjustment is set to the brightest setting.
If the tail lights are turned on when the surr oundings are dark, the meter’s brightness will
be reduced slightly. However, when the surro undings are bright, such as during the day-
time, the meter’s brightness w ill not be reduced even if th e tail lights are turned on.■
Customization

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, th e information display monitor may respond
slowly, and display changes may be delayed.
For example, there is a lag between the dr iver’s shifting and the new gear number
appearing on the display. This lag could ca use the driver to downshift again, causing
rapid and excessive engine braking and possibly an accident resulting in 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. 552)■
Voltmeter
When the voltmeter indicates 19 V or higher or 9 V or lower while the engine is run-
ning, there may be a battery or charging system malfunction. Have the vehicle
inspected at your Lexus dealer. ■
Engine oil pressure gauge
When the value of the engine oil pressure gauge drops while the engine is running,
stop the vehicle in a safe place immediat ely and check the amount of engine oil.
( → P. 475)
When the oil pressure drops even though th e engine oil amount has not decreased, or
if the oil pressure does not increase when engine oil is added, contact your Lexus
dealer, as there may be a problem with the lubrication system.
