Power steering Lexus ES300 2000 Owner's Manuals (in English)

STARTING AND DRIVING
307
CAUTION
Do not pump the brake pedal if the engine stalls.
Each push on the pedal uses up your reserved
vacuum.
 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 help
prevent lock±up of the wheels during a sudden
braking or braking on slippery road surfaces. This
assists in providing stability and steering
performance of the vehicle under these
circumstances.
Effective way to press the ABS brake pedal: When the
anti±lock brake system function is in action, just hold the
brake pedal down more firmly. Especially, in a panic stop,
you need to keep it depressed more firmly, and do not pump
the brake. Pumping the brake pedal makes the stopping
distance longer.

DRIVING TIPS
334
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
336
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 ªIf 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
368
CAUTION
Use extreme caution when towing the vehicle. Avoid
sudden starts or erratic driving maneuvers which would
place excessive stress on the emergency towing eyelet
and towing cable or chain. The eyelet and towing cable
or chain may break and cause serious injury or damage.
NOTICE
Use only a cable or chain specifically intended for use in towing vehicles. Securely fasten the cableor chain to the towing eyelet provided.
Before towing, release the parking brake and put the
transmission in ªNº. The ignition key must be in ªACCº
(engine off) or ªONº (engine running).
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.

MAINTENANCE
378
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
459 for additional information.
Engine coolant level
Make sure the coolant level is between the ªFULLº and
ªLOWº lines on the see±through reservoir when the
engine is cold. See page 407 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 443 for additional information.
Brake fluid level
Make sure the brake fluid level is correct. See page 416
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 402 for
additional information.
Power steering fluid level
Check the level through the reservoir. The level should
be in the ªHOTº or ªCOLDº range depending on the fluid temperature. See page 418 for additional information.
Exhaust system
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.)

CAUTION

When the engine is running, keep hands, clothing,
and tools away from the moving fan and engine drive
belt. (Removing rings, watches, and ties is
advisable.)

Right after driving, the engine compartment ± the
engine, radiator, exhaust manifold and power
steering fluid reservoir, etc. ± will be hot. So be
careful not to touch them. Oil and other fluids may
also be hot.

Do not smoke, cause sparks or allow open flames
around fuel or the battery. Their fumes are
flammable.

Be extremely cautious when working on the battery.
It contains poisonous and corrosive sulfuric acid.

Do not get under your vehicle with just the body jack
supporting it. Always use automotive jack stands or
other solid supports.

Use eye protection whenever you work on or under
your vehicle where you may be exposed to flying or
falling material, fluid spray, etc.
