OUTSIDE REAR VIEW MIRRORDEFOGGER SWITCH
To turn the electric outside rear view mirror defogger on,
push the switch.
The ignition key must be in the ªONº position.
The thin heater wires on the heater panels in the outside rear
view mirrors will quickly clear the surface. Keep your hands off
the mirror faces when the switch is on. An indicator light will
illuminate to indicate the defogger is operating.
The system will automatically shut off when the defogger has
operated about 5 minutes.
CAUTION
Since the mirror surfaces can get hot, do not touch them
when the switch is on.
If further defrosting or defogging is desired, simply actuate the
switch again. When the surface has cleared, push the switch
once again to turn the defogger off. Continuous use may cause
the battery to discharge, especially during stop±and±go
driving. The defogger is not designed to dry rain water or to
melt snow.
If the outside rear view mirrors are heavily coated with ice, use
a spray de±icer before operating the switch.
NOTICE
To prevent the battery from being discharged, turn the
switch off when the engine is not running.

ENGINE COOLANT
TEMPERATURE GAUGE
Normal range
The gauge indicates the engine coolant temperature when
the ignition switch is on. The engine operating
temperature w ill 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 coolingsystem 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 ªIf your vehicle overheatsº on page 496.

TACHOMETERThe 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. Thismay cause severe engine damage.

(a) Brake System Warning Light and Buzzer
This light comes on in the following cases when the ignition key
is in the ªONº position.
 When the parking brake is applied...
This light comes on for a few seconds when the ignition key is
in the ªONº position even after the parking brake is released.
 When the brake fluid level is low...
CAUTION
It is dangerous to continue driving normally when the
brake fluid level is low.
When the hydraulic brake booster fails...
If the hydraulic booster causes a problem resulting in poor
braking performance, the warning light comes on and buzzer
sounds continuously.
Have your vehicle checked at your Lexus dealer in the
following cases:
 The light does not come on even if the parking brake is
applied when the ignition key is in the ªONº position.
 The light does not come on even if the ignition key is turned
on with the parking brake released.
A warning light turning on briefly during operation does not
indicate a problem.
CAUTION
If any of the following conditions occurs, immediately
stop your vehicle at a safe place and contact your Lexus
dealer.
 The light does not turn off even after the parking
brake is released while the engine is running.
 The warning buzzer comes on together with the

work properly and your stopping distance will become
longer. Depress the brake pedal firmly and bring the
vehicle to an immediate stop.
 The brake system warning light remains on together
with the ªABSº warning light.
In this case, not only the anti±lock brake system will fail,
but also the vehicle will become extremely unstable
during braking.
