1999 Lexus ES300 brake

DRIVING TIPS
298See page 382 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 help.
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 freezing.
Use a washer fluid containing an antifreeze solution.
This product is available at your Lexus dealer and most
auto parts stores. Follow the manufacturer's directions
for how much to mix with water.
NOTICE
Do not use engine antifreeze or any other
substitute because it may damage your vehicle'spaint.
Do not use your parking brake when there is a
possibility it could freeze.
When parking, put the transmission into ºPº and block
the rear wheels. Do not use the parking brake, or snow
or water accumulated in and around the parking brake
mechanism may freeze the parking brake, making it hard to release.
Keep ice and snow from accumulating under the
fenders.
Ice and snow built up under your fenders can make
steering difficult. During bad winter driving, stop and
check under the fenders occasionally.

Brakes and safety chains
Lexus recommends trailers with brakes that
conform to any applicable federal and
state/provincial regulations.
 A safety chain must always be used between the
towing vehicle and the trailer. Leave sufficient
slack in the chain for turns. The chain should
cross under the trailer tongue to prevent the
tongue from dropping to the ground in case it
becomes damaged or separated. For correct
safety chain procedures, follow the hitch or trailer
manufacturer's recommendations.
CAUTION
 If the total trailer weight exceeds 450 kg (1000 lb.),
trailer brakes are required.
 Never tap into your vehicle's hydraulic system as it
will lower its braking effectiveness.
 Never tow a trailer without using a safety chain
securely attached to both the trailer and the vehicle.
If damage occurs to the coupling unit or hitch ball,
there is possible danger of the trailer wandering over
into another lane.

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

DRIVING TIPS
308parking on a slope with a trailer, but if it cannot be
avoided, do so only after performing the following:
1. Apply the brakes and keep them applied.
2. Have someone place wheel blocks under both the
vehicle and trailer wheels.
3. When the wheel blocks are in place, release your
brakes slowly until the blocks absorb the load.
4. Apply the parking brake firmly.
5. Shift into ºPº and turn off the engine.
When restarting out after parking on a slope:
1. With
the transmission in ºPº position, start the engine.
Be sure to keep the brake pedal depressed.
2. Shift into the º2º, ºLº or ºRº position.
3. Release the parking brake and brake pedal and
slowly pull or back away from the wheel blocks. Stop
and apply your brakes.
4. Have someone retrieve the blocks.
CAUTION
 Do not exceed 72 km/h (45 mph) or the posted towing
speed limit, whichever is lower. Because instability
(swaying) of a towing vehicle±trailer combination
usually increases as the speed increases, exceeding
72 km/h (45 mph) may cause loss of control.

DRIVING TIPS
309
Slow down and downshift before descending
steep or long downhill grades. Do not make
sudden downshifts.
 Avoid holding the brake pedal down too long or
too frequently. This could cause the brakes to
overheat and result in reduced braking
efficiency.
HOW TO SAVE FUEL AND
MAKE YOUR VEHICLE LAST
LONGER
Getting more kilometer/mileage from a liter/gallon of fuel
is easy ± just take it easy. It will help make your vehicle
last longer, too. Here are some specific tips on how to
save money on both fuel and repairs:
 Keep your tires inflated at the correct pressure.
Check the pressure every two weeks, or at least once
a month. Underinflation causes tire wear and wastes
fuel.
 Do not carry unneeded weight in your vehicle.
Excess weight puts a heavier load on the engine,
causing greater fuel consumption.
 Avoid lengthy warm±up idling. Once the engine is
running smoothly, begin driving ± but gently.
Remember, however, that on cold winter days this
may take a little longer. 
Accelerate slowly and smoothly. Avoid jackrabbit
starts.
 Avoid long engine idling. If you have a long wait
and you are not in traffic, it is better to turn off the
engine and start again later.
 Avoid engine overrevving . Use a gear position
suitable for the road on which you are traveling.
 Avoid continuous speeding up and slowing
down. Stop±and±go driving wastes fuel.
 Avoid unnecessary stopping and braking.
Maintain a steady pace. Try to time the traffic si gnals
so you only need to stop as little as possible or take
advantage of through streets to avoid traffic lights.
Keep a proper distance from other vehicles to avoid
sudden braking. This will also reduce wear on your
brakes.
 Avoid heavy traffic or traffic jams whenever
possible.
 Do not rest your foot on the brake pedal. This
causes needless wear, overheating and poor fuel
economy.
 Maintain a moderate speed on highways. The
faster you drive, the greater the fuel consumption. By
reducing your speed, you will cut down on fuel
consumption.
 Keep the front wheels in proper alignment. Avoid
hitting the curb and slow down on rough roads.

DRIVING TIPS
310Improper alignment not only causes faster tire wear
but also puts an extra load on the engine, which, in
turn, wastes fuel.
 Keep the bottom of your vehicle free from mud,
etc. This not only lessens weight but also helps
prevent corrosion. 
Keep your vehicle tuned±up and in top shape. A
dirty air cleaner, improper valve clearance, dirty
plugs, dirty oil and grease, brakes not adjusted, etc.
all lower engine performance and contribute to poor
fuel economy. For longer life of all parts and lower
operating costs, keep all maintenance work on
schedule, and if you often drive under severe
conditions, see that your vehicle receives more
frequent maintenance. (For scheduled maintenance
information, please refer to the separate ºOwner's
Manual Supplement/Maintenance Scheduleº.)
CAUTION
Never turn off the engine to coast down hills. Your
power steering and brake booster will not function
without the engine running. Also, the emission control
system operates properly only when the engine is
running.

IN CASE OF AN EMERGENCY
313
IF YOUR ENGINE STALLSWHILE DRIVING
If your engine stalls while driving . . . .
1. Reduce your speed gradually, keeping a straight line.
Move cautiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see ºIf your vehicle will not
startº.
CAUTION
If the engine is not running, the power assist for the
brakes and steering will not work, so steering and
braking will be much harder than usual.

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.?
