1999 Lexus ES300 coolant

STARTING AND DRIVING
2664. Release the parking brake and brake pedal.
Depress the accelerator pedal slowly for smooth
starting.
The vehicle will start in the first gear and automatically
shift to the most suitable gear for the running conditions,
such as the vehicle speed, hill climbing, hard towing, etc.
However, while the engine coolant temperature is low
and the vehicle is traveling at low speed, the
transmission will not shift into the overdrive gear even
with the overdrive switch on.
In ºDº position, the automatic transmission system will
select the most suitable gear for the running conditions
such as hill climbing, hard towing, etc.
If you need to accelerate rapidly while driving, push the
accelerator pedal all the way to the floor. The
transmission will automatically downshift to the third,
second or first gear, according to the vehicle speed.
If engine braking is needed, such as in descending a
long hill, see º(b) Using engine brakingº.

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.

DRIVING TIPS
307
wheels will be closer than the vehicle wheels to the
inside of the turn. Therefore, compensate for this by
making a larger than normal turning radius with your
vehicle.

Crosswinds and rough roads will adversely affect
handling of your vehicle and trailer, causing sway.
Pay attention to the rear from time to time to prepare
yourself for being passed by large trucks or buses,
which may cause your vehicle and trailer to sway. If
swaying happens, firmly grip the steering wheel and
reduce speed immediately but gradually. Never
increase speed. If it is necessary to reduce speed,
brake slowly. Steer straight ahead. If you make no
extreme correction with the steering or brakes, your
vehicle and trailer will stabilize.
 Be careful when passing other vehicles. Passing
requires considerable distance. After passing a
vehicle, do not forget the l ength of your trailer and be
sure you have plenty of room before changing lanes.
 In order to maintain efficient engine braking and
electrical charging performance, do not use
overdrive.
 Because of the added load of the trailer, your vehicle's
engine may overheat on hot days (at temperatures
over 30C [85F]) when going up a long or steep
grade with a trailer. If the engine coolant temperature
gauge indicates overheating, immediately turn off the
air conditioning (if in use), pull your vehicle off the
road and stop in a safe spot. See ºIf your vehicle
overheatsº on page 319 of this manual.
 Always place wheel blocks under both the vehicle
and trailer wheels when parking. Apply the parking
brake firmly. Put the transmission in ºPº. Avoid

(black) cable to a solid, stationary, unpainted
metallic point (e.g. cylinder head) away from the
battery. Do not connect it to or near any part that
moves when the engine is cranked.
CAUTION
When making the connections, to avoid serious injury,
do not lean over the battery or accidentally let the
jumper cables or clamps touch anything except the
correct battery terminals or the ground.
5. Start your engine in the normal way. After starting,
run it at about 2000 rpm for several minutes with the
accelerator pedal lightly depressed.
6. Carefully disconnect the cables in the exact reverse
order: the negative cable and then the positive cable.
7. Carefully dispose of the battery cover cloths which
may now contain sulfuric acid.
8. If removed, replace all the battery vent plugs.
If the cause of your battery discharging is not apparent
(for
example, lights left on), you should have it checked.IF YOUR VEHICLE OVERHEATS
If your engine coolant temperature gauge indicates
overheating, if you experience a loss of power, or if
you hear a loud knocking or pinging noise, the
engine has probably overheated.

IN CASE OF AN EMERGENCY
320
When the engine overheats
Pull safely off the road, stop the vehicle and turn on your
emergency flashers. Put the transmission in ºPº and
apply the parking brake.
A: If steam is coming from your engine:
Turn off the engine. Leave the hood closed until there
is no sign of steam or coolant. Your engine could have
been seriously damaged already. Call your Lexus
dealer for assistance.
CAUTION
To help avoid personal injury, keep the hood closed until
there is no steam. Escaping steam or coolant is sign of
very high pressure.
B: If no steam is coming from your engine:
Leave the engine running and turn off the air
conditioning. Check the following.
 Is the cooling fan operating?
 Is the coolant in the acceptable range?
 Is the engine drive belt O.K.?

IN CASE OF AN EMERGENCY
321
CAUTION
When the engine is running, keep hands and clothing
away from the moving fan and engine drive belt.
 Do not attempt to remove the radiator cap when the
engine and radiator are hot. Serious injury could
result from scalding hot fluid and steam blown out
under pressure.
If the cooling fan is not operating or the coolant is not in
the acceptable range, turn off the engine and call your
Lexus dealer.
If both conditions are O.K., after the engine coolant
temperature has cooled to normal, continue driving your
vehicle.
If the engine coolant temperature does not cool down, or
your vehicle overheats again, have it checked as soon
as possible by your Lexus dealer.IF YOU HAVE A FLAT TIRE
1. Reduce your speed gradually, keeping a straight line.
Move cautiously off the road to a safe place ± well away
from the traffic. Avoid stopping on the center divider of
a highway. Park on a level spot with firm ground.
2. Stop the engine and turn on your emergency flashers.
3. Firmly set the p arking brake and put the transmission
in ºPº.
4. Have everyone get out of the vehicle on the side away
from traffic.
5. Read the following instructions thoroughly.

MAINTENANCE
355
Engine compartment
Items listed below should be checked from time to
time, e.g. each time when refueling.
Washer fluid
Make sure there is sufficient fluid in the tank. See page
432 for additional information.
Engine coolant level
Make sure the coolant level is between the ºFULLº and
ºLOWº lines on the see±through reservoir when the
engine is cold. See page 383 for additional information.
Battery
Your Lexus has a maintenance free battery. You do not
have to add distilled water. For longer life of the battery,
however, see page 415 for additional information.
Brake fluid level
Make sure the brake fluid level is correct. See page 391
for additional information.
Engine oil level
Check the level on the dipstick with the engine turned off
and the vehicle parked on a level spot. See page 378 for
additional information.
Power steering fluid level
Check the level through the reservoir. The level should
be in the ºHOTº or ºCOLDº range depending on the fluid temperature. See page 393 for additional information.
Exhaust system
Look
for cracks, holes and loose supports. If you notice
any change in the sound of the exhaust or smell exhaust
fumes, have the cause located and corrected
immediately. (See engine exhaust cautions in Section
3±1.)

MAINTENANCE
356
DOES YOUR VEHICLE NEEDREPAIRING?
Be on the alert for changes in performance and sounds,
and 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, pedal almost touches floors, vehicle pulls to
one side when braking

Engine coolant temperature continually higher than
normal If you notice any of these clues, take your vehicle to your
Lexus dealer as soon as possible. It probably needs
adjustment or repair.
