Light control Lexus ES300 1998 s (in English) Owner's Guide

STARTING AND DRIVING
146
Resetting to a slower speed
Press the control lever downward in the ºSET/COASTº direction and hold \
it.
Release the lever when the desired speed is attained. While the lever is held
downward, the vehicle speed will gradually decrease.
When the difference between the actual vehicle speed and the set speed is less
than 5 km/h (3 mph), the set speed can be lowered 1.6 km/h (1 mph) e\
ach time
by pressing the control lever downward in the ºSET/COASTº direction
quickly.
However, a quicker way to reset is to depress the brake pedal and then press
the control lever downward in the ºSET/COASTº direction.
Even if you turn off the overdrive switch with the cruise control on, engine
braking will not be applied because the cruise control is not cancelled. To
decrease the vehicle speed, reset to a slower speed with the cruise control lever\
or depress the brake pedal. If you use the brake pedal, cruise control \
is
cancelled.
Resuming the preset speed
If the preset speed is cancelled by pulling the control lever or by depr\
essing
the brake pedal, pushing the lever up in the ºRES/ACCº direction will\
restore
the speed set prior to cancellation. However, once the vehicle speed falls
below about 40 km/h (25 mph), the preset speed will not be resumed.
Cruise control failure warning
If the ºCRUISEº indicator light in the instrument cluster flashes fi\
ve times and
then goes out when using the cruise control, it means that there is trouble in
the cruise control system. Contact your Lexus dealer.
ELECTRONIC MODULATED SUSPENSION
This electronic modulated suspension adjusts the damping effect on the
shock absorbers with the control switch. Select one of the 4 modes which
is suited to the driving conditions with the control switch to provide good
riding comfort and stability.

speed driving
2For moderate high speed driving
3For ordinary driving such as in the city traffic
4For driving on a bumpy road

STARTING AND DRIVING147
TRACTION CONTROL SYSTEM
The traction control system automatically helps control the spinning of
the front wheels which may occur when accelerating on slippery road
surfaces, thus assisting driver to control the driving power of the front
wheels.
31E013
When you turn the ignition switch on, this system always turns on. Leave
the system on during ordinary driving so that it can operate when needed.
When traction control is applied, the slip indicator light blinks.
31E014±1
You can turn off the traction control system by pushing the ºTRAC OFFº
switch. The ºTRAC OFFº indicator/warning light will then come on. Pushing
the ºTRAC OFFº switch a second time turns the system back on
and extinguishes the ºTRAC OFFº indicator/warning light.
When the traction control system is operating, you may feel vibration or nois\
e
of your vehicle, caused by operation of the brakes. This indicates the sy\
stem
is functioning properly.
When getting the vehicle out of mud or new snow, etc. the traction control
system will help operate to prevent the wheels from spinning.
Traction control failure warning
If the ºTRAC OFFº indicator/warning light flashes, contact your Lexus dealer
as soon as possible. There may be trouble in the traction control syste\
m.
CAUTION
Under certain slippery road conditions, full traction of the
vehicle and power to the front wheels cannot be maintained,
even though the traction control system is in operation. Do not
drive the vehicle under any speed or maneuvering conditions
which will cause the vehicle to lose traction. In situations
where the road surface is covered with ice or snow, your
vehicle should be fitted with snow tires or tire chains. Always
drive at an appropriate and cautious pace.

STARTING AND DRIVING
148
BRAKE SYSTEM
The tandem master cylinder brake system is a hydraulic system with two
separate sub±systems. If either sub±system should fail, the other will still
work. However, the pedal will be harder to press, and your stopping distance
will be longer. Also, the brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a single brake system.
Have your brakes fixed immediately.
Brake booster
The brake booster uses engine vacuum to power±assist the brakes. If the
engine should quit while you are driving, you can bring the vehicle to a stop
with normal pedal pressure. There is enough reserve vacuum for one or t\
wo
stops but no more!
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 f\
or you, just
hold the brake pedal down more firmly. Do not pump the brake. This will
result in reduced braking performance.
The brake pedal pulsation caused by the anti±lock brake system may indic\
ate
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 physic\
s
that act on your vehicle:
 Braking capability is dependent on tire friction with the road surface.

STARTING AND DRIVING149

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. ºABSº warning light
31E015
This light comes on when the ignition key is turned to the ºONº po\
sition.
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.

DRIVING TIPS
152
BREAK±IN PERIOD
Drive gently and avoid high speeds.
You need not follow a break±in schedule with your new Lexus. But follow\
ing
a few simple tips for the first 1600 km (1000 miles) can add to the fu\
ture
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 TIPS153
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 140.
 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.
 Do not continue normal driving when the brakes are wet. If they are
wet, your vehicle will r equire 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 ethylene±glycol antifreeze in the radiator.
NOTICE
Do not use alcohol type antifreeze.
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 219 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.
See page 200 for recommended viscosity. Leaving a heavy summer oil in your
vehicle during winter months may cause harder starting. If you are not sure
about which oil to use, call your Lexus dealer ± they will be pleased to h\
elp.
Check the electronic ignition system for loose connections or obvious
damage.
Keep the door locks from freezing.
Squirt lock de±icer or glycerine into the locks to keep them from fre\
ezing.

DRIVING TIPS157
Trailer towing tips
When towing a trailer, your vehicle will handle differently than when not
towing. The three main causes of vehicle±trailer accidents are driver
error, excessive speed and improper trailer loading. Keep these in mind
when towing: 
Before starting out, check the operation of the lights and all vehicle±trai\
ler
connections. After driving a short distance, stop and recheck the lights and
connections. Practice turning, stopping and backing with a trailer in an
area away from traffic until you learn the feel.
 Backing with a trailer is difficult and requires practice. Grip the bottom of
the steering wheel and move your hand to the left to move the trailer to\
the
left. Move your hand to the right to move the trailer to the right. (This
procedure is generally opposite to that when backing without a trailer.)
Also, just turn the steering wheel a little at a time, avoiding sharp or
prolonged turning. Have someone guide you when backing to reduce the
risk of an accident.
 Because stopping distance may be increased, vehicle±to±vehicle distance
should be increased when towing a trailer. For each 16 km/h (10 mph) of
speed, allow at least one vehicle and trailer length between you and the
vehicle ahead. Avoid sudden braking as you may skid, resulting in
jackknifing and loss of control. This is especially true on wet or slippery
surfaces.
 Avoid jerky starts or sudden acceleration.
 Avoid jerky steering and sharp turns. The trailer could hit your vehicle in
a tight turn. Slow down before making a turn to avoid the need of sudde\
n
braking.
 Remember that when making a turn, the trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Therefore, compensate for th\
is
by making a larger than normal turning radius with your vehicle.

MAINTENANCE
182
Tire rotation
Rotate the tires every 12000 km (7500 miles). See page 208 for additional
information.
Fluid leaks
Check underneath for leaking fuel, oil, water or other fluid after the vehicl\
e
has been parked for a while. If you smell fuel fumes or notice any leak, h\
ave
the cause found and corrected immediately.
Doors and engine hood
Check
that all doors, including trunk lid, operate smoothly and all latches lo\
ck
securely. Make sure the engine hood secondary latch secures the hood when
the primary latch is released.
Vehicle interior
Items listed below should be checked regularly, e.g. while performing
periodic services, cleaning the vehicle, etc.
Lights
Make sure the headlight, stop lights, tail lights, turn signal lights, and o\
ther
lights are working. Check headlight aim.
Service reminder indicators and warning buzzers
Check that all service reminder indicators and warning buzzers function
properly.
Steering wheel
Check that it has the specified freeplay. Be alert for changes in steering
condition, such as hard steering, excessive freeplay or strange noise.
Seats
Check that all front seat controls such as seat adjusters, seatback recliner, etc.
operate smoothly. Check that the head restraints move up and down smoothly
and that the locks hold securely in any latched position.
Seat belts
Check that the seat belt system such as buckles, retractors and anchors operat\
e
properly and smoothly. Make sure the belt webbing is not cut, frayed, worn
or damaged.

ENGINE195
FUEL
Fuel type
Your vehicle must use only unleaded gasoline.
To help prevent gas station mixups, your Lexus has a smaller fuel tank
opening. The special nozzle on pumps with unleaded fuel will fit it, but the
larger nozzle on pumps with leaded gas will not.
At a minimum, the gasoline you use should meet the specifications of ASTM
D4814 in the U.S.A. and CGSB 3.5±M93 in Canada.
NOTICE
Do not use leaded gasoline. Use of leaded gasoline will cause the
three±way catalytic converter/warm up three±way catalytic converter to
lose its effectiveness and the emission control system to function
improperly. Also, this can increase maintenance costs.
Octane rating
Select Octane Rating 87 (Research Octane Number 91) or higher. For
improved vehicle performance, the use of premium unleaded gasoline
with an Octane Rating of 91 (Research Octane Number 96) or higher is
recommended.
Use of unleaded fuel with an Octane Rating or Research Octane Number
lower than stated above will cause persistent heavy knocking. If it is sever\
e,
this will lead to engine damage. If your engine knocks ...
If you detect heavy knocking even when using the recommended fuel, or if\
you hear steady knocking while holding a steady speed on level roads, consu\
lt
your Lexus dealer.
However, now and then, you may notice light knocking for a short time while
accelerating or driving up hills. This is no cause for concern.
Gasolines containing detergent additives
Lexus recommends use of gasolines that contain detergent additives to
avoid build±up of engine deposits.
For further details, ask your Lexus dealer or a local gasoline retailer.
Improved gasolines
The American Automobile Manufacturers Association (AAMA) has
developed a specification of improved gasolines. The AAMA
specification offers optimal fuel information for better vehicle
performance and better protection of your engine.
Lexus recommends the use of gasolines that meet the AAMA specification,
if available, for improved drivability and emission control system.

CHASSIS

REPLACING WHEELS
When to replace your wheels
If you have wheel damage such as bending, cracks or heavy corrosion, the
wheel should be replaced.
If you fail to replace damaged wheels, a tire may slip off a wheel or they may
cause loss of handling control.
Replacement with used wheels is not recommended as they may have been
subjected to rough treatment or high mileage and could fail without warning.
Also, bent wheels which have been straightened may have hidden structural
damage and therefore should not be used. Never use an inner tube in a leaking
wheel which is designed for a tubeless tire.
Wheel selection
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim width, and
offset.
Correct replacement wheels are available at your Lexus dealer.
A wheel of a different size or type may adversely affect handling, wheel and
bearing life, brake cooling, speedometer/odometer calibration, stopping
ability, headlight aim, bumper height, vehicle ground clearance, and tire or
snow chain clearance to the body and chassis.
ALUMINUM WHEEL PRECAUTIONS
 After driving your vehicle the first 1600 km (1000 miles), check that the
wheel nuts are tight.
 If you have rotated, repaired, or changed your tires, check that the whe\
el
nuts are still tight after driving 1600 km (1000 miles).
 When using tire chains, be careful not to damage the aluminum wheels.
 Use only the Lexus wheel nuts and wrench designed for your aluminum
wheels.
 When balancing your wheels, use only Lexus balance weights or
equivalent and a plastic or rubber hammer.
 As with any wheel, periodically check your aluminum wheels for damage.
If damaged, replace immediately.
SUSPENSION AND CHASSIS
CAUTION
Do not modify the suspension/chassis with lift kits, spacers,
springs, etc. It can cause dangerous handling characteristics,
resulting in loss of control.
