1351-8. Safety information
1
Before driving Your vehicle is equipped with AD VANCED AIRBAGS designed based
on the US motor vehicle safety st andards (FMVSS208). The airbag sen-
sor assembly (ECU) controls airbag deployment based on information
obtained from the sensors etc. show n in the system components diagram
above. This information includes cras h severity and occupant informa-
tion. As the airbags deploy, a chemica l reaction in the inflators quickly fills
the airbags with non-toxic gas to he lp restrain the motion of the occu-
pants. ■
If the SRS airbags deploy (inflate) ●
Bruising and slight abrasions may result from contact with a deploying (inflating)
SRS airbag.●
A loud noise and white powder will be emitted.●
Parts of the airbag module (steering wheel hub, airbag cover and inflator) as
well as the seats, parts of the front and rear pillars, and roof side rails, may be hot
for several minutes. The airbag itself may also be hot.●
The windshield may crack.●
For Safety Connect subscriber s, if the SRS airbags deploy or in the event of a
severe rear-end collision, the system is designed to send an emergency call to
the response center, notifying them of the vehicle’s location (without needing to
push the “SOS” button) and an agent will attempt to speak with the occupants
to ascertain the level of emergency and assistance required. If the occupants
are unable to communicate, the agent automatically treats the call as an emer-
gency and helps to dispatch the necessary emergency services. (  P. 6 2 6 )■
SRS airbag deployment conditions (SRS front airbags) ●
The SRS front airbags will deploy in the event of an impact that exceeds the
set threshold level (the level of force corresponding to an approximately 12 -
18 mph [20 - 30 km/h] frontal collision with a fixed wall that does not move or
deform).
However, this threshold velocity will be considerably higher in the following situa-
tions:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which
can move or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in which
the front of the vehicle “underrides”, or goes under, the bed of a truck

Before driving ●
The surface of the seats with the side air-
bag is scratched, cracked, or otherwise
damaged.
●
The portion of the front pillars, rear pillars
or roof side rail garnishes (padding) con-
taining the curtain shield airbags inside is
scratched, cracked, or otherwise dam-
aged.

Before driving CAUTION■
SRS airbag precautions
●
The SRS front passenger airbag also depl oys with considerable force, and can
cause death or serious injury especially if the front passenger is very close to the
airbag. The front passenger seat should be as far from the airbag as possible with
the seatback adjusted, so the front passenger sits upright.●
Improperly seated and/or restrained infants and children can be killed or seri-
ously injured by a deploying airbag. An infant or child who is too small to use a
seat belt should be properly secured using a child restraint system. Lexus strongly
recommends that all infants and children be placed in the rear seats of the vehicle
and properly restrained. The rear seats ar e safer for infants and children than the
front passenger seat. (  P. 1 5 0 ) ●
If the seat belt extender has been con-
nected to the front seat belt buckles but the
seat belt extender has not also been fas-
tened to the latch plate of the seat belt, the
SRS front airbags will judge that the driver
and front passenger are wearing the seat
belt even though the seat belt has not been
connected. In this case, the SRS front air-
bags may not activate correctly in a colli-
sion, resulting in death or serious injury in
the event of a collision. Be sure to wear the
seat belt with the seat belt extender.

1421-8. Safety information
CAUTION■
SRS airbag precautions ●
Do not sit on the edge of the seat or lean
against the dashboard.
●
Do not allow a child to stand in front of the
SRS front passenger ai rbag unit or sit on
the knees of a front passenger. ●
Do not allow the front seat occupants to
hold items on their knees.
●
Do not lean against the door, the roof side
rail or the front, side and rear pillars.
●
Do not allow anyone to kneel on the pas-
senger seats toward the door or put their
head or hands outside the vehicle.

1441-8. Safety information
CAUTION■
SRS airbag precautions ●
Do not place anything, such as a cushion, on the front passenger's seat. Doing so
will disperse the passenger's weight, wh ich prevents the sensor from detecting
the passenger's weight properly. As a re sult, the SRS front passenger airbag may
not deploy in the event of a collision.■
Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perfor m any of the followin g modifications with-
out consulting your Lexus dealer.
The SRS airbags may malfunction or deploy (inflate) accidentally, causing death or
serious injury. ●
Installation, removal, disassembly and repair of the SRS airbags●
Repairs, modifications, removal or replac ement of the steering wheel, instrument
panel, dashboard, seats or seat upholstery, front, side and rear pillars or roof side
rails●
Repairs or modifications of the front fend er, front bumper, or side of the occupant
compartment●
Installation of a grille guard (bull bars, kangaroo bar, etc.), snow plows or winches●
Modifications to the vehi cle's suspension system●
Installation of elec tronic devices such as mobile two-way radios or CD players●
Modifications to your vehicle for a person with a physical disability

Before driving CAUTION■
Front passenger occupant classi fication system precautions●
Do not recline the front passenger seatback so far that it touches a rear seat. This
may cause the “AIR BAG OFF” indicator ligh t to be illuminate d, which indicates
that the passenger’s airbags will not deploy in the event of a severe accident. If the
seatback touches the rear se at, return the seatback to a position where it does
not touch the rear seat. Keep the front pa ssenger seatback as upright as possible
when the vehicle is moving. Reclining the seatback excessively may lessen the
effectiveness of the seat belt system.●
If an adult sits in the front passenger se at, the “AIR BAG ON” indicator light is illu-
minated. If the “AIR BAG OFF” indicator is illuminated, ask the passenger to sit
up straight, well back in the seat, feet on the floor, and with the seat belt worn cor-
rectly. If the “AIR BAG OFF” indicator still rema ins illuminated, either ask the pas-
senger to move to the rear seat, or if th at is not possible, move the front passenger
seat fully rearward.●
When it is unavoidable to install the forw ard-facing child restraint system on the
front passenger seat, install the child rest raint system on the front passenger seat
in the proper order. (  P. 1 5 4 )●
Do not modify or remove the front seats.●
Do not kick the front passenger seat or subject it to severe impact. Otherwise,
the SRS warning light may come on to indicate a malfunction of the detection sys-
tem. In this case, contact your Lexus dealer immediately.●
Child restraint systems installed on the rear seat should not contact the front seat-
backs.●
Do not use a seat accessory, such as a cushion or seat cover, that covers the seat
cushion surface.●
Do not modify or replace the upholstery of the front seat.

1541-8. Safety information

When driving NOTICE■
To prevent water damage
Take all necessary safety measures to ensure that water damage to the hybrid bat-
tery, hybrid system or other components does not occur. ●
Water entering the engine compartment may cause severe damage to the hybrid
system. Water entering the interior may cause the hybrid battery stowed under
the rear seats to short circuit.●
Water entering the hybrid transmission will cause deterioration in transmission
quality. The malfunction indicator may come on, and the vehicle may not be driv-
able.●
Water can wash the grease from wheel bearings, causing rusting and premature
failure, and may also enter the hybrid transmission case, reducing the gear oil’s
lubricating qualities.■
When you drive through water
If driving through water, such as when crossing shallow streams, first check the
depth of the water and the bottom of the riverbed for firmness. Drive slowly and
avoid deep water.■
Inspection after off-road driving ●
Sand and mud that has accumulated around brake discs may affect braking effi-
ciency and may damage brake system components.●
Always perform a maintenance inspection after each day of off-road driving that
has taken you through rough terrain, sand, mud, or water. For scheduled mainte-
nance information, refer to the “Warra nty and Services Guide/Owner’s Manual
Supplement/Schedul ed Maintenance”.
