ON-VEHICLE INSPECTION
1. INSPECT BRAKE BOOSTER
(a) Air tightness check.
(1) Start the engine and stop it after 1 or 2 minutes. De-
press the brake pedal several times slowly.
HINT:
If the pedal goes down farthest the 1st time, but gradually rises
after the 2nd or 3rd time, the booster is air tight.
(2) Depress the brake pedal while the engine is run-
ning, and stop the engine with the pedal depressed.
HINT:
If there is no change in the pedal reserve distance after holding
the pedal for 30 seconds, the booster is air tight.
(b) Operating check.
(1) Depress the brake pedal several times with the igni-
tion switch OFF and check that there is no change
in the pedal reserve distance.
(2) Depress the brake pedal and start the engine.
HINT:
If the pedal goes down slightly, operation is normal.
2. INSPECT VACUUM CHECK VALVE
(a) Check vacuum check valve.
(1) Slide the clip and disconnect the vacuum hose.
(2) Remove the vacuum check valve.
(3) Check that there is ventilation from the booster to
engine, and no ventilation from the engine to the
booster.
(4) If any fault is found, replace the vacuum check
valve.

PASSENGER AIRBAG INDICATOR LAMP
Models:
'04 ± '05 ES 330 & RX 330
Technical Service
Information Bulletin
February 22, 2005
EL002-05
The passenger airbag indicator lamp may switch from ON to OFF for front seat
passengers weighing approximately less than 100 pounds, depending on their seating
position. It is important for the front seat passengers to know that proper operation of the
advanced frontal airbag system is highly dependent on the pressure placed on the seat
bottom. Situations that add or subtract sensed weight can result in occupant
misclassification. To minimize this situation:
Check seating posture.
± Passengers should be seated upright with their back against the seatback and
feet on the floor.
Check loading conditions.
± Extra weight from items such as bags or groceries or toys hanging on the
seatback can add to the sensed weight of the front seat passenger.
± A rear seat passenger lifting the front seat with their legs, objects placed under
the front seat, or the front seatback in contact with the rear seat can subtract from
the sensed weight of the front seat passenger.
If the passenger airbag indicator lamp continues to switch ON to OFF after checking the
above conditions, perform the following repair procedure.
NOTE:
The safest place for children is in the rear seat.
Please note that Lexus recommends
that you NEVER
install a rear±facing child restraint in the front passenger seat, even if
the passenger ªAirbag OFFº lamp is illuminated. Please refer to the Owner's Manual
for additional details.
