are turned on.
NOTICE■
To prevent damage to the engine and its components ●
Do not let the indicator needle of the ta chometer enter the red zone, which indi-
cates the maximum engine speed. ●
The engine may be overheating if the engine coolant temperature gauge is in the
red zone (“H”). In this case, immediatel y stop the vehicle in a safe place, and
check the engine after it has cooled completely. ( P. 8 7 3 )■
Vo l t m e t e r
When the voltmeter indicates 19 V or higher or 9 V or lower while the engine is
running, there may be a battery or chargi ng 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 immediately and check the amount of engine oil.
( P. 74 9 )
When the oil pressure drops even though the 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.
