1999 Lexus ES300 brake

STARTING AND DRIVING
287
CAUTION
Do not pump the brake pedal if the engine stalls.
Each push on the pedal uses up your vacuum
reserve.
 Even if the power assist is completely lost, the brakes
will still work. But you will have to push the pedal
hard ± much harder than normal. And your braking
distance will be longer.

Anti±lock brake system
The anti±lock brake system is designed to
automatically help prevent lock±up of the wheels
during a sudden brake or braking on slippery road
surfaces. This assists in providing directional
stability and steering performance of the vehicle
under these circumstances.
The anti±lock brake system becomes operative after the
vehicle has accelerated to a speed in excess of
approximately 10 km/h (6 mph). It stops operating when
the vehicle decelerates to a speed below approximately
5 km/h (3 mph).
You may hear a sound in the engine compartment for a
few seconds when the engine is started or just after the
vehicle is started. This means that the anti±lock brake
system is in the self±check mode, and does not indicate
a malfunction.
Effective way to press the ABS brake pedal: When the
anti±lock brake system function is in action, you may feel the
brake pedal pulsating and hear a noise. In this situation, to
let the anti±lock brake system work for you, just hold the
brake pedal down more firmly. Do not pump the brake in a
panic stop. Pumping the brake pedal makes the stopping
distance longer.

STARTING AND DRIVING
289
The brake pedal pulsation caused by the anti±lock brake
system may indicate hazardous road surface
conditions. Although the anti±lock brake system assists
in providing vehicle control, it is still important to drive
with all due care, because the anti±lock brake system
cannot overcome the laws of physics that act on your
vehicle:

Braking capability is dependent on tire friction with the
road surface. 
Even though the anti±lock brake system is operating,
a driver cannot maintain full control on certain
slippery road surfaces, when cornering at high
speeds, or in violent maneuvers.
 Avoid high speeds on wet roads. The anti±lock brake
system cannot eliminate the risk of hydroplaning and
loss of tire friction.
Always maintain a safe distance from the vehicle in front
of you. Compared with vehicles not fitted with an
anti±lock brake system, your vehicle may require a
longer stopping distance in the following cases:
 Driving on rough, gravel or snow±covered roads.
 Driving with tire chains installed.
 Driving on roads where the road surface is pitted or
has other differences in surface height.

STARTING AND DRIVING
291
This light comes on when the ignition key is turned
to the ºONº position. After about a few seconds, the
light will go off.
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.
Even if the anti±lock brake system should fail, the brake
system will still operate conventionally. But when the
ºABSº warning light is on (and the brake system warning
light is off), anti±lock brake system is not assisting brake
performance so that the wheels could lock up during a
sudden brake or braking on slippery road surfaces.
Have your vehicle checked by your Lexus dealer as
soon as possible.
Drum±in±disc type parking brake system
Your vehicle has a drum±in±disc type parking brake
system. This type of brake system needs
bedding±down of the brake shoes periodically or
whenever the parking brake shoes and/or drums are
replaced.
Have your Lexus dealer perform the bedding±down.

BRAKE PAD WEAR LIMITINDICATORS
31E016
The brake pad wear limit indicators on your disc
brakes give a warning noise when the brake pads
are worn to the extent that replacement is required.
If you hear a squealing or scraping noise while driving,
have the brake pads checked and replaced by your
Lexus dealer as soon as possible. Expensive rotor
damage can result if the pads are not replaced when
needed.TYPES OF TIRES
Determine what kind of tires your vehicle is originally
equipped with.

DRIVING TIPS
295
BREAK±IN PERIOD
Drive gently and avoid high speeds.
You need not follow a break±in schedule with your new
Lexus. But following a few simple tips for the first 1600
km (1000 miles) can add to the future economy and long
life of your vehicle:
Do not drive over 88 km/h (55 mph).
 Avoid overrevving. Maintain engine speed between
2000 and 4000 rpm.
 Avoid full±throttle starts.
 Try to avoid hard stops during the first 300 km (200
miles).
 Do not drive for a long time at any single speed, either
fast or slow.
 Do not tow a trailer during the first 800 km (500 miles).
OPERATION IN FOREIGN
COUNTRIES
If you plan to drive your Lexus in another country ...
First, comply with the vehicle registration laws.
Second, confirm the availability of the correct fuel
(unleaded and minimum octane rating).
TIPS FOR DRIVING IN VARIOUS CONDITIONS
Always slow down in gusty crosswinds. This will
allow you much better control.
 Drive slowly onto curbs and, if possible, at a right
angle. Avoid driving onto high, sharp±edged objects
and other road hazards. Failure to do so can lead to
severe tire damage resulting in tire bursts.
 When parking on a hill, turn the front wheels until they
touch the curb so that the vehicle will not roll. Apply
the parking brake, and place the transmission in ºPº.
If necessary, block the wheels.
 Washing your vehicle or driving through deep water
may get the brakes wet. To see whether they are wet,
check that there is no traffic near you and then press
the pedal lightly. If you do not feel a normal braking
force, the brakes are probably wet. To dry them, drive
the vehicle cautiously while lightly pressing the brake
pedal with the parking brake applied. If they still do
not work safely, pull to the side of the road and call a
Lexus dealer for assistance.

DRIVING TIPS
296
CAUTION
Before driving off, make sure the parking brake is
fully released and that the parking brake reminder
light is off.
 Do not rest your foot on the brake pedal while driving.
It can cause dangerous overheating, needless wear,
and poor fuel economy.
 To drive down a long or steep hill, reduce your speed
and downshift. Remember, if you ride the brakes
excessively, they may overheat and not work
properly. See page 267.
 Be careful when accelerating, upshifting,
downshifting or braking on a slippery surface. The
abrupt change in engine speed, such as sudden
acceleration or engine braking, could cause the
vehicle to spin or skid.
 Do not drive in excess of the speed limit. Even if the
legal speed limit permits it, do not drive over 140 km/h
(85 mph) unless your vehicle has high±speed
capability tires. Driving over 140 km/h (85 mph) may
result in tire failure, loss of control and possible
injury. Be sure to consult a tire dealer to determine
whether the tires on your vehicle are high±speed
capability tires or not before driving at such speeds.

DRIVING TIPS
297
Do not continue normal driving when the
brakes are wet. If they are wet, your vehicle will
require a longer stopping distance, and it may
pull to one side when the brakes are applied.
Also, the parking brake will not hold the vehicle
securely.WINTER DRIVING TIPS
Make sure you have a proper freeze protection of
engine coolant.
Your coolant must contain ethylene±glycol type coolant
for a proper corrosion protection of aluminum
components. Use ºToyota Long Life Coolantº or
equivalent. See ºChecking the engine coolant levelº on
page 383 for instructions.
NOTICE
Do not use alcohol type antifreeze or plain water alone.
When it is extremely cold, we recommend to use 60%
solution for your Lexus, to provide protection down to
about ±50 C (±58 F). Do not use more than 70%
solution for better coolant performance.
Check the condition of the battery and cables.
Cold temperatures reduce the capacity of any battery, so
it must be in top shape to provide enough power for
winter starting. Page 415 tells you how to visually
inspect the battery. Your Lexus dealer and most service
stations will be pleased to check the battery charge
level.
Make sure the engine oil viscosity is suitable for the
cold weather.
