GAUGES, METERS AND SERVICE REMINDER INDICATORS

ENGINE COOLANT
TEMPERATURE GAUGE
 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.
 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 the temperature of the engine within the
specified operating range.
 Do not continue driving with an overheated engine.
See “If your vehicle overheats” on page 303.

GAUGES, METERS AND SERVICE REMINDER INDICATORS
61
If any 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.
 The light does not come on when the ignition key is turned
to the “ON” position or remains on for more than 6 seconds.
 The light comes on while driving.
(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.
(f) Low Engine Oil Pressure Warning Light
This light warns that the engine oil pressure is too low.
If it flickers or stays on while you are driving, pull off the road
to a safe place and stop the engine immediately. Call a Lexus
dealer or qualified repair shop for assistance.
The light may occasionally flicker when the engine is idling or
it may come on briefly after a hard stop. There is no cause for
concern if it then goes out when the engine is accelerated
slightly.
The light may come on when the oil level is extremely low. It
is not designed to indicate low oil level, and the oil level must
be checked using the oil level dipstick.
NOTICE
Do not drive the vehicle with the warning light on —
even for one block. It may ruin the engine.
