To turn the wipers on, move the lever down until you reach
the desired speed setting.
The ignition switch must be in the ONº position.
There are 3 settings:
AUTOº position: Automatic operation
LOº position: Low speed operation
HIº position: High speed operationAutomatic operation
The wiper speed is determined by the amount of raindrops
and sunlight detected by the automatic wiper control
sensor.
Twist the automatic control adjuster in the ±º direction to
lower the sensitivity, and the +º direction to boost the
sensitivity.
The sensor is on the inside of the windshield as shown above.
Even if the wiper lever is in the AUTOº position, the system will
switch to intermittent operations in the following conditions:
When the windshield gets extremely cold (at less than
±10C or 14F)
When the system malfunctions
However, when the windshield gets extremely hot (at more
than 90C or 194F), the wipers do not operate even if the
wiper lever is in the AUTOº position.

This light and buzzer remind you to buckle up the driver's seat
belt.
Once the ignition key is turned to ONº or STARTº, the
reminder light and buzzer come on if the driver's seat belt is not
fastened. Unless the driver fastens the belt, the light stays on
and the buzzer stops after about 4 to 8 seconds.
(c) Front Passenger's Seat Belt Reminder Light
This light reminds you to buckle up the front passenger's seat
belt.
Once the ignition key is turned to the ONº position, the
reminder light flashes if a front passenger sits in the front
passenger seat and does not fasten the seat belt.
If luggage or other load is placed on the front passenger seat,
depending on its weight, the reminder light may come on.
(d) SRS Warning Light
This light comes on when the ignition key is turned to the
ONº position. It goes off after about 6 seconds. This
means the SRS airbags and front seat belt pretensioners
are operating properly.
This warning light system monitors the airbag sensor
assembly, front airbag sensors, side and curtain shield airbag
sensor assemblies, curtain shield airbag sensor assemblies,
driver's seat position sensor, driver's seat belt buckle switch,

passenger's seat belt buckle switch, front seat belt
pretensioner assemblies, inflators, warning light,
interconnecting wiring and power sources.

OCCUPANT RESTRAINT SYSTEM
120
Seat belt pretensioners
The driver and front passenger's seat belt pretensioners
are designed to be activated in response to a severe
frontal impact.
When the sensor detects a severe frontal impact, the front seat
belts are quickly drawn back by the retractors so that the belts
snugly restrain the front seat occupants.
The front passengers's seat belt pretensioner will not activate
if no passenger is detected in the front passenger seat by the
front passenger occupant classification system. However, the
front passenger's seat belt pretensioner may activate if
luggage is put on the seat, or the seat belt is buckled up
regardless of the presence of an occupant in the seat. (As for
the front passenger occupant classification system, see page
152.)
The seat belt pretensioners and SRS airbags may not operate
together in case of collisions at a certain speeds and angles.

OCCUPANT RESTRAINT SYSTEM
121 The front seat belt pretensioner system consists mainly of the
above components, and their locations are shown in the
illustration.
The front seat belt pretensioners are controlled by the airbag
sensor assembly. The airbag sensor assembly consists of a
safing sensor and airbag sensor.
When the front seat belt pretensioners are activated, an
operating noise may be heard and a small amount of non-toxic
gas may be released. This does not indicate that a fire is
occurring. This gas is normally harmless.Once the front seat belt pretensioners have been activated, the
seat belt retractors remain locked.
CAUTION
Do not modify, remove, strike or open the front seat belt
pretensioner assemblies, airbag sensor or surrounding
area or wiring. Failure to follow these instruction may
prevent the seat belt pretensioners from activating
correctly, cause sudden operation of the system or
disable the system, which could result in death or
serious injury. Consult your Lexus dealer about any
repairs and modifications.
