FRONT SEATS
Front seat precautions
CAUTION
The SRS side airbags are installed in the driver and front
passenger seats. Observe the following precautions.
Do not lean over the front door when the vehicle is in use.
The side airbag inflates with considerable speed and force;
you may be killed or severely injured.
 Do not modify or replace the seats or the surface of the seats
with side airbags. Such changes may disable the system, or
cause the side airbags to inflate, resulting in death or
serious injury. Consult your Lexus dealer.
 Do not use accessories for the seats which cover the parts
where the side airbags should inflate. Such accessories may
prevent the side airbags from activating correctly, causing
death or serious injury.
Seat adjustment precautions
Adjust the driver's seat so that the foot pedals, steering wheel and instrument
panel controls are within easy reach of the driver.
CAUTION
 Do not adjust the seat while the vehicle is moving as the seat
may unexpectedly move and cause the driver to lose control
of the vehicle.
 Be careful not to hit the seat against a passenger, luggage or
the rear seat.
NOTICE
Do not operate the control switch in more than one dimension at a time.
It may cause electrical overload.

COMFORT ADJUSTMENT59
Adjusting seatback angle
16E143
Move the control switch in the desired direction.
Releasing the switch will stop the seatback in that position.
CAUTION
To reduce the risk of sliding under the lap belt during a
collision, avoid reclining the seatback any more than needed.
The seat belts provide maximum protection in a frontal or rear
collision when the driver and the passenger are sitting up
straight and well back in the seats. If you are reclined, the lap
belt may slide past your hips and apply restraint forces
directly to the abdomen. Therefore, in the event of a frontal
collision, the risk of personal injury may increase with
increasing recline of the seatback.
Adjusting seat cushion angle and height
16E144
Move the control switch in the desired direction.
Releasing the switch will stop the seat cushion in that position.

16E013

1Day 2Night
When driving at night, pull the lever toward you to reduce the glare from
the headlights of vehicles behind you.
Before adjusting the mirror to the position with most clarity, push the
day±night change lever forward (daylight driving position).
Remember that by reducing glare you also lose some rear view clarity.
SEAT BELTS
Seat belt precautions
Lexus strongly urges that the driver and passengers in the vehicle be properly
restrained at all times with the seat belts provided. Failure to do so could
increase the chance of injury and/or the severity of injury in accidents.
Child. Use a child restraint system appropriate for the child until the child
becomes large enough to properly wear the vehicle's seat belts. See ºChild
restraintº for details.
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. According to accident
statistics, the child is safer when properly restrained in the rear seat than in the\
front seat.
If a child must sit in the front seat, the seat belts should be worn properl\
y. Do
not let the child sit on your lap. It does not provide sufficient restraint. If an
accident occurs and the seat belts are not worn properly, the force of the rapid
inflation of the airbag may cause severe injury to the child.
Do not allow the child to stand up or kneel on either rear or front seats. An
unrestrained child could suffer serious injury during emergency braking or a
collision.

COMFORT ADJUSTMENT69
SUPPLEMENTAL RESTRAINT SYSTEM(SRS)
The Supplemental Restraint System (SRS) consists of driver and front
passenger airbags, side airbags and seat belt pretensioners. The
combination of these 3 systems is designed to provide further protection
for the driver and front passenger when added to the primary pr otection
provided by the seat belts.
16E124

Driver and front passenger airbags, and seat belt pretensioners
Driver and front passenger airbags:
In response to a severe frontal impact, the driver and front passenger
airbags work together with the seat belts to help preventing or reduce
injury by inflating, in order to decrease the likelihood of the driver's or
front passenger's heads or chests from directly hitting the steering wheel
or dashboard. Seat belt pretensioners:
In response to a severe frontal impact, the seat belts are quickly drawn
back in by the retractors so that the belts snugly restrain the driver and
front passenger.
The front passenger airbag is activated even with no passenger in the front\
seat.
The seat belt pretensioners are activated together with the driver and fron\
t
passenger airbags, even with no passenger in the front seat.
Be sure to wear your seat belt.
CAUTION
The driver or front passenger too close to the steering wheel
or dashboard during airbag deployment can be killed or
seriously injured. Lexus strongly recommends that:

The driver sit as far back as possible from the steering
wheel while still maintaining control of the vehicle.
 The front passenger sit as far back as possible from the
dashboard.
 All vehicle occupants be properly restrained using the
available seat belts.

16E125±1

Side airbags
Side airbags:
In response to a severe side impact, the side airbag for the driver or front
passenger works together with the seat belt to help preventing or
reducing injury by inflating, in order to decrease the impact mainly on the
driver or front passenger's chest.
The side airbag on the passenger seat is activated even with no passenge\
r in
the front seat.
Be sure to wear your seat belt.
CAUTION
SRS side airbags inflate with considerable force. To avoid
potential death or serious injury during inflation of a side
airbag, Lexus strongly recommends that the driver and front
passenger;
 Wear their seat belt.
 Remain properly seated with their back against the seat at
all times.
16E022
The indicator comes on when the ignition key is turned to the ºACCº o\
r
ºONº position. It goes off after about 6 seconds. This means the SRS is
operating properly.
The SRS warning light system monitors the airbag sensor assemblies,
inflators, seat belt pretensioners, warning light, interconnecting wiring and
power sources.

COMFORT ADJUSTMENT71
16E023
The driver and front passenger airbags and seat belt pretensioners are
designed to activate in response to a severe frontal impact within the
shaded area between the arrows in the illustration.
There may be the case that the driver and passenger airbags and seat belt
pretensioners will not activate with such an impact in which the occupan\
t
wearing the seat belt correctly would not get serious injury.
The driver and front passenger airbags and seat belt pretensioners will wor\
k
if the severity of the impact is above the designed threshold level, compa\
rable
to an approximate 20 km/h (14 mph) collision when impacting straight i\
nto
a fixed barrier that does not move or deform.
If the severity of the impact is below the above threshold level, the driv\
er and
front passenger airbags and seat belt pretensioners may not work. However, this threshold velocity will be considerably higher if the vehicle
strikes an object, such as a parked vehicle or sign pole, which can move or
deform on impact, or if it is involved in an underride collision (e.g. a collisio\
n
in which the nose of the vehicle ºunderridesº, or goes under, the bed of a
truck).
It is possible with collision severity at the marginal level of driver and
passenger airbag sensor detection and activation that only one of your
vehicle's driver and front passenger airbags and seat belt pretensioners will
work.
For the safety of all occupants, be sure to always wear seat belts.

1Collision from the rear
2Vehicle roll±over
The driver and front passenger airbags and seat belt pretensioners are
not designed to inflate if the vehicle is subjected to a rear impact, if it r olls
over, or if it is involved in a low±speed frontal collision.
The side airbags are designed to inflate when the passenger compartment
gets a severe impact from the side.
The side airbags may rather not to activate in the impact in which the occu\
pant
wearing the seat belt correctly would not get serious injury.
16E135

1 Collision from the side at an angle
2Collision from the side to the vehicle body other
than the passenger compartment
The side airbags may not inflate if the vehicle is subjected to a collis\
ion from the side at an angle, or a collision to the side of the vehicle body ot\
her
than the passenger compartment, which impact is not severe enough for
the passenger compartment.

COMFORT ADJUSTMENT73
16E136

Vehicle roll±over
The side airbags are not designed to inflate if the vehicle is rolled over.
If the impact on the body of the passenger compartment is not strong as
illustrated above, the relevant side airbag may not inflate.

6SRS warning light
7Driver and front passenger airbag sensor assembly
The SRS airbag sensor assemblies consist of a safing sensor and driver and
front passenger airbag sensor.
In a severe frontal impact, the driver and front passenger airbag sensor d\
etects
deceleration and the system triggers the front airbag inflators and seat belt
pretensioners. In a severe side impact, the side airbag sensor triggers the side
airbag inflator. Then a chemical reaction in the inflators momentarily fills the
airbags with non±toxic gas to help restrain the forward or lateral motion of \
the
occupants. Then the inflators fill the airbags and the seat belts are quickly
drawn back in by the retractors to help restrain forward motion of the
occupants.
When the SRS operates, it produces a fairly loud noise and release some
smoke along with non±toxic gas. This does not indicate a fire. Be sure to wash
off any residue as soon as possible to prevent minor skin irritation.
Deployment of the airbags happen in a fraction of a second, so the airbags
must inflate with considerable force. While the system is designed to reduc\
e

COMFORT ADJUSTMENT

serious injuries, it may also cause minor burns or abrasions and swellings.
Parts of the airbag module (steering wheel hub, dashboard, front seats)\
may
be hot for several minutes, but the airbags themselves will not be hot. \
The
airbags are designed to inflate only once.
A crash severe enough to inflate the driver and front passenger airbags \
may
break
the windshield as the vehicle buckles. In vehicles with a front passeng\
er
airbag, the windshield may also be damaged by absorbing some of the force
of the inflating airbag.
CAUTION
 The SRS is designed only as a supplement to the primary
protection of the driver side and front passenger side seat
belt systems. The front seat occupants can be killed or
seriously injured by an inflating airbag if they do not wear
the available seat belts. During sudden braking just before
a collision, an unrestrained driver or front passenger can
move forward into direct contact with or close proximity to
the airbag which may then deploy during the collision. To
obtain maximum protection in an accident, the driver and
all passengers in the vehicle must wear their seat belts.
Wearing a seat belt during an accident reduces the chances
of death or serious injuries or being thrown out of the
vehicle. For instructions and precautions concerning the
seat belt system, see ºSeat beltsº on page 64.
 Improperly seated and/or restrained infants and children
can be killed or seriously 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 seat of the vehicle and properly
restrained. The rear seat is the safest for infants and
children. For instructions concerning the installation of a
child restraint system, see ºChild restraintº on page 80 .
