Tachometer - Lexus GS300 1998 Owner's Manual

"Normal range
The gauge indicates the engine coolant temperature when
the ignition switch is on. The engine operating
temperature will vary with changes in weather and engine
load.
If the needle points to the red zone or higher, stop your vehicle
and allow the engine to cool.
Your vehicle may overheat during severe operating
conditions, such as:
D Driving up a long hill on a hot day.
D Reducing speed or stopping after high speed driving.
D Idling for a long period with the air conditioning on in
stop–and–go traffic.
NOTICE
D Do not remove the thermostat in the engine cooling
system as this may cause the engine to overheat. The
thermostat is designed to control the flow of coolant to
keep the temperature of the engine within the specified
operating range.
D Do not continue driving with an overheated engine.
See "If your vehicle overheats" on page 312.
