(a) Brake System Warning Light and Buzzer
This light comes on in the following cases when the ignition key
is in the “ON” position.
 When the parking brake is applied...
This light comes on for a few seconds when the ignition key is
turned to the “ON” position even after the parking brake is
released.
If the vehicle speed rises above 5 km/h (3 mph) with the parking
brake applied, a buzzer sounds.
 When the brake fluid level is low...
CAUTION
It is dangerous to continue driving normally when the
brake fluid level is low.
Have your vehicle checked at your Lexus dealer in the
following case:
The light does not come on even if the parking brake is
applied when the ignition key is in the “ON” 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 either 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.
In this case, the brakes may not 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 “ABS” warning light.
In this case, not only the antilock brake system will
fail but also the vehicle will become extremely
unstable during braking.

visual tip −offs that indicate service is needed. Some important
clues are:
 Engine missing, stumbling, or pinging
 Appreciable loss of power
 Strange engine noises
 A fluid leak under the vehicle (However, water dripping from
the air conditioning after use is normal.)
 Change in exhaust sound (This may indicate a dangerous
carbon monoxide leak. Drive with the windows open and
have the exhaust system checked immediately.)
 Flat−looking tires, excessive tire squeal when cornering,
uneven tire wear
 Vehicle pulls to one side when driving straight on a level
road
 Strange noises related to suspension movement
 Loss of brake effectiveness, spongy feeling brake pedal,

INTRODUCTION

Use eye protection whenever you work on or under
your vehicle where you may be exposed to flying or
falling material, fluid spray, etc.
 Take care when filling the brake fluid reservoir
because brake fluid can harm your eyes and damage
painted surfaces. If fluid gets in your eyes, flush your
eyes with clean water immediately. If you still feel
uncomfortable with your eyes, go to the doctor.
 Be extremely cautious when working on the battery.
It contains poisonous and corrosive sulfuric acid.NOTICE
Remember that battery and ignition cables carry high
currents or voltages. Be careful of accidentally
causing a short circuit.
 Before closing the engine hood, check to see that you
have not forgotten any tools, rags, etc.
 Do not drive with the air cleaner removed, or
excessive engine wear could result. Also backfiring
could cause a fire in the engine compartment.
 If you spill the fluid, be sure to wash it off with water
to prevent it from damaging the parts or paint.
 Do not overfill automatic transmission fluid and
power steering fluid, or the transmission and power
steering could be damaged.
 Be careful not to scratch the glass surface with the
wiper frame.
