ENGINE COOLANT
TEMPERATURE GAUGE
SV13012

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:
 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.
NOTICE
Do not remove the thermostat in the engine cooling
system as this may cause the engine to overheat. Thethermostat is designed to control the flow of coolantto keep the temperature of the engine within thespecified operating range.
Do not continue driving with an overheated engine.See ºIf your vehicle overheatsº on page 202.

(d) SRS Warning Light
The indicator comes on when the ignition key is turned to
the ºACCº or ºONº position. It goes off after about 6
seconds. This means the SRS airbags and front seat belt
pretensioners are operating properly.
The warning light system monitors the airbag sensor
assembly, front airbag sensors, side airbag sensors, door side
airbag sensors, front seat belt pretensioner assemblies,
inflators, warning light, interconnecting wiring and power
sources.
If either of the following conditions occurs, this indicates a
malfunction somewhere in the parts monitored by the warning
light system. Contact your Lexus dealer as soon as possible
to service the vehicle.
 When the ignition key is turned to the ºACCº or ºONº
position, the light does not come on, remains on or flashes.
 The light comes on or starts flashing while driving.
If the light stays on, it indicates that the driver and front
passenger airbags fail. If the light flashes, the side airbags
and/or seat belt pretensioners fail.
(e) Discharge Warning Light
This light warns that the battery is being discharged.
If it comes on while you are driving, stop the vehicle, turn off the
engine, and check for the cause. Look first at the engine drive
belt.
 If it is loose or broken, the generator will not charge the
battery properly.
 If the belt is O.K., there is a problem somewhere in the
charging system.
The engine ignition will continue to operate, however, until the
battery is discharged. Turn off the air conditioning, blower,
radio, etc., and drive directly to the nearest Lexus dealer or
repair shop.
NOTICE
Do not continue driving if the engine drive belt is broken or loose.
