CAUTION■
SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury. ●
The driver and all passengers in the vehicle must wear their seat belts properly.
The SRS airbags are supplemental devices to be used with the seat belts.●
The SRS driver airbag deploys with considerable force, and can cause death or
serious injury especially if the driver is very close to the airbag. The National
Highway Traffic Safety Administration (“NHTSA”) advises:
Since the risk zone for driver’s airbag is the first 2 - 3 in. (50 - 75 mm) of inflation,
placing yourself 10 in. (250 mm) from your driver airbag provides you with a
clear margin of safety. This distance is measured from the center of the steering
wheel to your breastbone. If you sit less than 10 in. (250 mm) away now, you can
change your driving position in several ways:
• Move your seat to the rear as far as you can while still reaching the pedals
comfortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many dr ivers can achieve the 10 in. (250 mm)
distance, even with the driver seat all the way forward, simply by reclining the
back of the seat somewhat. If reclining the back of your seat makes it hard to
see the road, raise yourself by using a firm, non-slippery cushion, or raise the
seat if your vehicle has that feature.
• If your steering wheel is adjustable, ti lt it downward. This points the airbag
toward your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA above, while still main-
taining control of the foot pedals, steering wheel, and your view of the instrument
panel controls.

Front passenger occupant classi fication system precautions
Observe the following precautions regarding the front passenger occupant classifi-
cation system.
Failure to do so may cause death or serious injury. ●
Wear the seat belt properly.●
Make sure the front passenger’s seat belt tab has not been left inserted into the
buckle before someone sits in the front passenger seat.●
Make sure the “AIR BAG OFF” indicator light is not illuminated when using the
seat belt extender for the front passen ger seat. If the “AIR BAG OFF” indicator
light is illuminated, disconnect the extender tongue from the seat belt buckle,
then reconnect the seat belt. Reconnect the seat belt extender after making sure
the “AIR BAG ON” indicator light is illuminated. If you use the seat belt extender
while the “AIR BAG OFF” indicator light is illuminated, the SRS airbags for the
passenger may not activate correctly, which could cause death or serious injury
in the event of collision.
●
Do not apply a heavy load to the front passenger seat or equipment.
●
Do not put weight on the front passenger seat by putting your hands or feet on
the front passenger seat seatback from the rear passenger seat.
●
Do not let a rear passenger lift the front passenger seat with their feet or press on
the seatback with their legs.
●
Do not put objects under the front passenger seat.

1491-8. Safety information

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.

1521-8. Safety information
CAUTION■
Child restraint precautions ●
For effective protection in automobile accidents and sudden stops, a child must
be properly restrained, using a seat belt or child restraint system depending on
the age and size of the child. Holding a chil d in your arms is not a substitute for a
child restraint system. In an accident, th e child can be crushed against the wind-
shield, or between you and the vehicle's interior. This may cause death or serious
injury to the child in the event of a sudden stop or an accident.●
Lexus strongly urges the use of a proper child restraint system that 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.●
Never install a rear-facing child restraint system on the front passenger seat even
if the “AIR BAG OFF” indicator light is illumi nated. In the event of an accident, the
force of the rapid inflation of the front passenger airbag can cause death or seri-
ous injury to the child if a rear-facing child restraint system is installed on the front
passenger seat.●
A forward-facing child restraint system may be installed on the front passenger
seat only when it is unavoidable. A child restraint system that requires a top tether
strap should not be used in the front passenger seat since there is no top tether
strap anchor for the front passenger seat. Adjust the seatback as upright as possi-
ble and always move the seat as far back as possible even if the “AIR BAG OFF”
indicator light is illuminated, because th e front passenger airbag could inflate with
considerable speed and force. Otherwise, the child may be killed or seriously
injured.●
Do not use the seat belt extender when installing a child restraint system on the
front or rear passenger seat. If installing a child restraint system with the seat belt
extender connected to the seat belt, the seat belt will not securely hold the child
restraint system, which could cause death or serious injury to the child or other
passengers in the event of a sudden stop, sudden swerve or accident.
●
Do not allow the child to lean his/her head or any part of his/her body against the
door or the area of the seat, front and rear pillars or roof side rails from which the
SRS side airbags or SRS curtain shield airbags deploy even if the child is seated in
the child restraint system. It is dangerous if the side airbags and curtain shield air-
bags inflate, and the impact could cause death or serious injury to the child.

Before driving CAUTION■
When installing a child restraint system
Follow the directions given in the child re straint system installa tion manual and fix
the child restraint system securely in place.
If the child restraint system is not correctl y fixed in place, the child or other passen-
gers may be injured or even killed in the event of sudden braking, sudden swerving
or an accident.
●
When installing a child restraint system in the rear center seat, adjust both seat
cushions to the same position and align both seatbacks at the same angle. The
seatbacks must be adjusted to the same angle. Otherwise, the child restraint sys-
tem cannot be securely restrained and this may cause death or serious injuries in
the event of sudden braking, sudden swerving or an accident.
●
When using the LATCH system, move the seat as far back as possible and adjust
the seatback as upright as possible.
●
When a booster seat is installed, always ensure that the shoulder belt is posi-
tioned across the center of the child's shoulder. The belt should be kept away
from the child's neck, but not so that it could fall off the child's shoulder. Failing to
do so may result in death or serious inju ry in the event of sudden braking, sudden
swerving or an accident. ●
If the driver’s seat interferes with the child
restraint system and prevents it from being
attached correctly, attach the child restraint
system to the right-hand rear seat. ●
Adjust the front passen ger seat so that it
does not interfere with the child restraint
system. ●
Only put a forward-facing child restraint
system on the front seat when unavoidable.
When installing a forward-facing child
restraint system on the front passenger
seat, move the seat as far back as possible
even if the “AIR BAG OFF” indicator light is
illuminated. Failure to do so may result in
death or serious injury if the airbags deploy
(inflate).
