GAUGES, METERS AND SERVICE REMINDER INDICATORS
47
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
stopandgo 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 263.
TACHOMETER
13E064
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.

(c) Front Passenger’s Seat Belt ReminderLight
This light reminds you to buckle up the front passenger’s seat
belt.
Once the ignition key is tur ned to the “ON” position, the
reminder light flashes if a front passenger sits in the front
passenger seat and does not fasten the seat belt. Unless the
front passenger fastens the belt, the light keeps flashing.
If luggage load is placed on the front passenger seat,
depending on its weight and how it is placed on the seat,
builtin sensors in the seat cushion may detect the pressure,
causing the reminder light to come on.
(d) SRS Warning Light
This light comes on when the ignition key is turned to the
“ON” position. It goes off after about 6 seconds. This
means the SRS airbags and seat belt pretensioners are
operating properly.
This warning light system monitors the airbag sensor
assembly, front airbag sensors, side and curtain shield airbag
sensor assemblies, curtain shield airbag sensor assemblies,
driver’s seat position sensor, driver’s seat belt buckle switch,
front seat belt pretensioner assemblies, inflators, warning light,
interconnecting wiring and power sources. 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 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 airbags fail. If the light flashes, the side and curtain
shield 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.
