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 ªIf your vehicle overheatsº on page
165.
TACHOMETER
The tachometer indicates engine speed in thousands of
rpm (revolutions per minute). Use it while driving to
prevent engine overrevving.
Driving with the engine turning too fast causes excessive
engine wear and poor fuel econmy. 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.

32If the brake fluid is correct ...
Have the warning system checked by your Lexus dealer.
(b) Seat Belt Reminder Light and Buzzer
Once the ignition key is turned ªONº or ªSTARTº, 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 Airbag Warning Light
This indicator comes on when the ignition key is turned
to the ªACCº or ªONº position. It goes off after about 6
seconds. This means the SRS airbag system is
operating properly.
The SRS airbag warning light system monitors the airbag
sensor assembly, 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.
The light does not come on as described above or remains
on.
The light comes on while driving.
(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 is broken
or loose.
