GAUGES, METERS AND SERVICE REMINDER INDICATORS29
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 traf\
fic.
 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 ºIf your
vehicle overheatsº on page 166.
TACHOMETER
13E003
The tachometer indicates engine speed in thousands of rpm (revolutions
per minute). Use it while driving to prevent engine overrevving.
Driving with the engine running too fast causes excessive engine wear and
poor fuel economy. Remember, in most cases the slower the engine speed, the
greater the fuel economy.
NOTICE
Do not let the indicator needle get into the red zone. This may cause
severe engine damage.

If the brake fluid level is correct ...
Have the warning system checked by your Lexus dealer.
(b) Seat Belt Reminder Light and Buzzer
Once the ignition key is turned to ºONº or ºSTARTº, the reminder light and
buzzer come on if the driver's seat belt is not fastened. Unless the driver
fastens the belt, the light stays on and the buzzer stops after about 4 to 8
seconds.
(c) SRS Warning Light
The indicator comes on when the ignition key is turned to the ºACCº o\
r
ºONº position. It goes off after about 6 seconds. This means the SRS is
operating properly.
The SRS warning light system monitors the airbag sensor assemblies,
inflators, seat belt pretensioners, 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.

The light does not come on as described above.
 The light stays 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 air\
bags fail.
If the light flashes, the side airbags and/or seat belt pretensioners fa\
il.
(d) 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.
