ENGINE COOLANT
TEMPERATURE GAUGE
13E018

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.

GAUGES, METERS AND SERVICE REMINDER INDICATORS

Your vehicle may overheat during severe operating
conditions, such as:

Driving up a long hill on a hot day.
 Reducing speed or stopping after high speed driving.
 Idling for a long period with the air conditioning on in
stop±and±go traffic.
 Towing a trailer.
NOTICE
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 thetemperature of the engine within the specifiedoperating range.
Do not continue driving with an overheatedengine. See ªIf your vehicle overheatsº onpage 348.

AIR CONDITIONING
225
The air intake control button is used to switch the air
intake between the OUTSIDE AIR mode and
RECIRCULATED AIR mode.
With the button in the OUTSIDE AIR mode, the
OUTSIDE AIR mode indicator light will come on and the
system will take fresh outside air into the vehicle.
If quick circulation of cooled air is desired, push the air
intake control button for RECIRCULATED AIR. The
RECIRCULATED AIR mode indicator light will come on.
For normal use, it is best to keep the air intake control
button set to OUTSIDE AIR mode. If recirculated air is
used
during heating, the windows will fog up more easily.
When the air conditioning is ON, if the engine coolant
temperature becomes extremely high, the
RECIRCULATED AIR mode is automatically selected.
This is not a malfunction. When the engine coolant
temperature is lowered, the previous mode resumes.
If manual on±off of the air conditioning is desired ±
Push the ªA/Cº button to turn the air conditioning on and
push it again to turn the air conditioning off.
The air conditioning does not work if the outside
temperature is lowered down to around 0 C (32F).
If the system is used for ventilation, heating in dry
weather or removing frost or exterior fog on the
windshield, turn the air conditioning off once it is no
longer required. This will improve fuel economy. The air
conditioning can be used for year±round automatic temperature
control including cooling and dehumidifying
operation.
If the air conditioning compressor does not operate, the
indicator of the ªA/Cº button will blink. If the indicator of
the ªA/Cº button blinks even when the ªA/Cº button is
pushed again, have the compressor checked by your
nearest Lexus dealer.
Displaying the outside temperature ±
When you push the ªOUTSIDE TEMPº knob, the
temperature display shows the outside temperature. To
return to the display of the current set temperature, push
the knob again. The temperature display ranges from
±30 C (±22 F) up to 50C (122F).
