This indicator comes on when the ignition key is turned to
the “ON” position. It goes off after about 6 seconds. This
means the SRS front airbags 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,
front passenger occupant classification system and indicator
light, front passenger’s seat belt buckle switch, seat belt
pretensioner assemblies, inflators, roll sensing of curtain
shield airbags off indicator light, interconnecting wiring and
power sources. (For details, see “Service reminder indicators
and warning buzzers” on page 52.)

If any of the following conditions occurs, this indicates a
malfunction of the airbags or seat belt pretensioners. Contact
your Lexus dealer as soon as possible.

The light does not come on when the ignition key is turned
to the “ON” position or remains on for more than 6 seconds
or flashes.
 The light comes on or starts flashing while driving.
The SRS warning light will come on and front passenger
occupant classification indicator light will indicate “OFF” if
there is a malfunction in the front passenger occupant
classification system.

In the following cases, contact your Lexus dealer as soon as
possible:
 The SRS front airbags have been inflated.
 The front of the vehicle (shaded in the illustration) was
involved in an accident that was not severe enough to cause
the SRS front airbags to inflate.

The SRS side airbag and curtain shield airbag system consists
mainly of the above components, and their locations are
shown in the illustration.
The SRS side airbag and curtain shield airbag system is
controlled by the airbag sensor assembly. The airbag sensor
assembly consists of a safing sensor and airbag sensors. In a severe side impact, the side and curtain shield airbag
sensor and/or the curtain shield airbag sensor trigger(s) the
side airbag inflators and/or the curtain shield airbag inflators.
In a vehicle rollover, the airbag sensor assembly triggers the
curtain shield airbag inflator. At this time a chemical reaction
in the inflators very quickly fills the airbags with non
−toxic gas
to help restrain the forward or lateral motion of the front and
second seat occupants.
When the airbags inflate, they produce a loud noise and
release some smoke and residue along with non −toxic gas.
This does not indicate a fire. This smoke may remain inside
the vehicle for some time, and may cause some minor irritation
to the eyes, skin or breathing. Be sure to wash off any residue
as soon as possible to prevent any potential skin irritation with
soap and water. If you can safely exit from the vehicle, you
should do so immediately.
Deployment of the airbags happens in a fraction of a second,
so the airbags must inflate with considerable force. While the
system is designed to reduce serious injuries, it may also
cause minor burns or abrasions and swelling.
Front seats as well as parts of the front and rear pillars, and roof
side rail may be hot for several minutes, but the airbags
themselves will not be hot. The airbags are designed to inflate
only once.

Failure to follow these instructions can result in death
or serious injury. Consult your Lexus dealer about any
repair and modification.
If you wish to modify your vehicle for a person with a
physical disability, consult your Lexus dealer. It may
dangerously interfere with the SRS side airbags and
curtain shield airbags operation.
NOTICE
Do not perform any of the following changes without
consulting your Lexus dealer. Such changes can
interfere with proper operation of the SRS side airbag
and curtain shield airbag system in some cases.
Installation of electronic devices such as a mobile
twoway radio, cassette tape player or CD player.
 Modification of the side structure of the passenger
compartment.
 Repairs made on or near the console, or front seats.

*1: The system judges a person of adult size as an adult. When a smaller adu\
lt sits in the front passenger seat, the system may
recognize him/her as a child depending on his/her physique and posture.
*2: When a larger child who has outgrown a child restraint system sits in the front\
passenger seat, the system may recognize him/heras an adult depending on his/her physique or posture.
*3: Never install a rear −facing child restraint system on the front passenger seat. A forward −facing child restraint system should only
be installed on the front passenger seat when it is unavoidable. (See “\
Child restraint” on page 162 as for installing the child restraint system.)
*4: When the front passenger does not wear a seat belt.

OCCUPANT RESTRAINT SYSTEMS
162
When it is unavoidable to install the forwardfacing
child restraint system on the front passenger seat,
install the child restraint system on the front
passenger seat in the proper order. (As for the
installation order, see “Ins tallation with 3point type
seat belt” on page 171.)
Do not remove the front seats.
Do not kick the front passe nger seat or subject it to
severe impact. Otherwise, the SRS warning light may
come on to indicate a malfunction of the detection
system. In this case, cont act your Toyota dealer
immediately.
The front passenger occupant classification indicator light may
indicate “ON” when a child sits in, or a forward −facing child
restraint system is installed on the front passenger seat. If the
“OFF” indicator is not illuminated in these circumstances, the
front passenger airbag and side airbag on the front passenger
side are in an active condition—the airbags will deploy if an
impact meets the deployment criteria. Refer to all the cautions
in this section, and “Child restraint” that follows.
CHILD RESTRAINT
Child restraint precautions
Lexus strongly urges the use of appropriate child
restraint systems for children.
The laws of all 50 states in the U.S.A. and Canada now require
the use of a child restraint system.
Your vehicle conforms to SAE J1819.
If a child is too large for a child restraint system, the child should
sit in the rear seat and must be restrained using the vehicle’s
seat belt. See “Seat belts” on page 121 for details.
CAUTION
 For effective protection in automobile accidents and
sudden stops, a child must be properly restrained,
using a seat belt or child restraint depending on age
and size of the child. Holding a child in your arms is
not a substitute for a child restraint system. In an
accident, the child can be crushed against the
windshield, or between you and the vehicle’s interior.
 Lexus strongly urges use of a proper child restraint
system which conforms to the size of the child
installed on the rear seat. According to accident
statistics, the child is safer when properly restrained
in the rear seat than in the front seat.

If this warning light comes on, the bulb of the
nearinfrared floodlight (night view projector) has blown

CRUISE CONTROL
The cruise control is designed to maintain a set cruising
speed without requiring the driver to operate the
accelerator. Cruising speed can be set to any speed
above 40 km/h (25 mph).
Within the limits of the engine’s capabilities, cruising speed can
be maintained up or down grades. However, changes in
vehicle speed may occur on steeper grades.
When the cruise control is on, the driving pattern of the
automatic transmission is fixed in the normal position,
regardless of the position of the driving pattern selector switch.
CAUTION
To help maintain maximum control of your vehicle,
do not use the cruise control when driving in heavy
or varying traffic, or on slippery (rainy, icy or
snowcovered) or winding roads.
 Avoid vehicle speed increases when driving
downhill. If the vehicle speed is too fast in relation to
the cruise control set speed, cancel the cruise
control then downshift the transmission to use
engine braking to slow down.
