CAUTION
To avoid serious personal injury, you must do the
following.
Before you close the power windows, always make
sure there is nobody around the power windows. You
must also make sure the heads, hands and other
parts of the bodies of all occupants are kept
completely inside the vehicle. If someone's neck,
head or hands get caught in a closing window, it
could result in a serious injury. When anyone closes
the power windows, make sure he or she operates the
windows safely.
 When small children are in the vehicle, never let them
use the power window switches without supervision.
Use the window lock switch to prevent them from
making unexpected use of the switches.
 Never leave small children alone in the vehicle,
especially with the ignition key still inserted. They
could use the power window switches and get
trapped in a window. Unattended children can be
involved in serious accidents.
 Never try jamming any part of your body to make the
jam protection function work intentionally.
 The jam protection function may not work if
something gets caught just before the window fully
closed.
EMERGENCY FLASHER SWITCH
SV12023
To turn on the emergency flashers, push the switch.
All the turn signal lights will flash. The emergency flashers will
work with the engine running or off and with or without the

Turn on the emergency flashers to warn other drivers if you
must stop your vehicle where it might be a traffic hazard.
Always pull your vehicle as far off the road as possible.
The turn signal light switch will not work when the emergency
flashers are in operation.
NOTICE
To prevent the battery from being discharged, do not
leave the switch on longer than necessary when theengine is not running.

FUEL GAUGE
SV13017

Low fuel level warning light
The gauge indicates the approximate quantity of the fuel
remaining in the tank when the ignition switch is on.
It is a good idea to keep the tank over 1/4 full.
If the fuel level approaches ºEº or the low fuel level warning light\
comes on, fill the fuel tank as soon as possible.
On inclines or curves, due to the movement of fuel in the tank,
the fuel gauge needle may fluctuate or the low fuel level
warning light may come on earlier than usual.
If the fuel tank is completely empty, the malfunction indicator
lamp comes on. Fill the fuel tank immediately.The indicator lamp goes off after driving several times. If the
indicator lamp does not go off, contact your Lexus dealer as
soon as possible.
See the inner back cover for fuel capacity and recommended
fuel selection.

ENGINE COOLANT TEMPERATUREGAUGE
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 271.

VOLTMETER
SV13021

1Discharge warning light 2Normal range
The voltmeter tells whether the battery is charged or
discharged. Check it while the engine is running ± the
needle should always indicate as shown above.
If the needle reads below or above the normal range while the
engine is running, it indicates that the charging system needs
immediate repair.
However, it is normal for the needle to drop below the normal
range during engine starting.
MOMENTARY FUEL CONSUMPTIONMETER

GAUGES, METERS AND SERVICE REMINDER INDICATORS

The momentary fuel consumption is calculated and
indicated based on the driving distance and the fuel
consumption with the engine running.
If you are driving at low speeds just before stopping, the
accurate figure may not be shown.
TACHOMETER
SV13016
The tachometer indicates engine speed in thousands of
rpm (revolutions per minute). Use it while driving to
prevent engine over±revving.
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.
