WARNING
■General precautions while driving
Driving under the infl uence: Never drive
your vehicle when under the influence of
alcohol or drugs that have impaired your
ability to operate your vehicle. Alcohol
and certain drugs delay reaction time,
impair judgment an d reduce coordina-
tion, which could lead to an accident that
could result in death or serious injury.
Defensive driving: Always drive defen-
sively. Anticipate mi stakes that other
drivers or pedestrians might make and
be ready to avoid accidents.
Driver distraction: Always give your full
attention to driving. Anything that dis-
tracts the driver, such as adjusting con-
trols, talking on a cellular phone or
reading can result in a collision with
resulting death or serious injury to you,
your occupants or others.
■General precaution regarding chil-
dren’s safety
Never leave children unattended in the
vehicle, and never allow children to have
or use the key.
Children may be able to start the vehicle
or shift the vehicle into neutral. There is
also a danger that children may injure
themselves by playing with the windows,
the moon roof (if equipped) or other fea-
tures of the vehicle. In addition, heat
build-up or extremely cold temperatures
inside the vehicle can be fatal to children.

depress the pedals fully and so that
your arms bend slightly at the
elbow when gripping the steering
wheel. ( P.102)
Lock the head restraint in place
with the center of the head restraint
closest to the top of your ears.
(  P.107)
Wear the seat belt correctly.
(  P.24) Make sure that all occupants are wear-
ing their seat belts before driving the
vehicle. (

Use a child restraint system appropri-
ate for the child until the child becomes
large enough to properly wear the
vehicle’s seat belt. ( P.41)
Make sure that you can see backward
clearly by adjusting the inside and out-
side rear view mirrors properly.
(  P.110, 112)

WARNING
■For safe driving
Observe the following precautions.
Failure to do so may result in death or
serious injury.
A
B
C
D
●Do not adjust the position of the
driver’s seat while driving.
Doing so could cause the driver to lose
control of the vehicle.
●Do not place a cushion between the
driver or passenger and the seatback.
A cushion may prevent correct pos-
ture from being achieved, and reduce
the effectiveness of the seat belt and
head restraint.
●Do not place anything under the front
seats.
Objects placed under the front seats
may become jammed in the seat
tracks and stop the seat from locking in
place. This may lead to an accident
and the adjustment mechanism may
also be damaged.
●Always observe the legal speed limit
when driving on public roads.
●When driving over long distances, take
regular breaks before you start to feel
tired.
Also, if you feel tired or sleepy while
driving, do not force yourself to con-
tinue driving and take a break immedi-
ately.

241-1. For safe use
Seat belts
Make sure that all occupants are
wearing their seat belts before driv-
ing the vehicle.
WARNING
Observe the following precautions to
reduce the risk of injury in the event of
sudden braking, sudden swerving or an
accident.
Failure to do so may cause death or seri-
ous injury.
■Wearing a seat belt
●Ensure that all passengers wear a seat
belt.
●Always wear a seat belt properly.
●Each seat belt should be used by one
person only. Do not use a seat belt for
more than one person at once, includ-
ing children.
●Lexus recommends that children be
seated in the rear seat and always use
a seat belt and/or an appropriate child
restraint system.
●To achieve a proper seating position,
do not recline the seat more than nec-
essary. The seat belt is most effective
when the occupants are sitting up
straight and well back in the seats.
●Do not wear the shoulder belt under
your arm.
●Always wear your seat belt low and
snug across your hips.
■Pregnant women
Obtain medical advice and wear the seat
belt in the proper way. (
P.25)
Women who are pregnant should posi-
tion the lap belt as low as possible over
the hips in the same manner as other
occupants, extending the shoulder belt
completely over the shoulder and avoid-
ing belt contact with the rounding of the
abdominal area.
If the seat belt is not worn properly, not
only the pregnant woman, but also the
fetus could suffer death or serious injury
as a result of sudden braking or a colli-
sion.
■People suffering illness
Obtain medical advice and wear the seat
belt in the proper way. (
P.25)
■When children are in the vehicle
P.48
■Seat belt damage and wear
●Do not damage the seat belts by allow-
ing the belt, plate, or buckle to be
jammed in the door.
●Inspect the seat belt system periodi-
cally. Check for cuts, fraying, and loose
parts. Do not use a damaged seat belt
until it is replaced. Damaged seat belts
cannot protect an occupant from
death or serious injury.

For safety and security
Extend the shoulder belt so that it
comes fully over the shoulder, but
does not come into contact with the
neck or slide off the shoulder.
 Position the lap belt as low as possi-
ble over the hips.
 Adjust the position of the seatback.
Sit up straight and well back in the
seat.
 Do not twist the seat belt.
■Child seat belt usage
The seat belts of your vehicle were princi-
pally designed for persons of adult size.
●Use a child restraint system appropriate
for the child, until the child becomes large
enough to properly wear the vehicle’s
seat belt. ( P.41)
●When the child becomes large enough to
properly wear the vehicle’s seat belt, fol-
low the instructions regarding seat belt
usage. ( P.24)
■Seat belt extender
If your seat belts cannot be fastened
securely because they are not long enough,
a personalized seat belt extender is avail-
able from your Lexus dealer free of charge.
WARNING
●Ensure that the belt and plate are
locked and the belt is not twisted.
If the seat belt do es not function cor-
rectly, immediately contact your Lexus
dealer.
●Replace the seat assembly, including
the belts, if your vehicle has been
involved in a serious accident, even if
there is no obvious damage.
●Do not attempt to install, remove,
modify, disassemble or dispose of the
seat belts. Have an y necessary repairs
carried out by your Lexus dealer. Inap-
propriate handling may lead to incor-
rect operation.
Correct use of the seat belts
WARNING
■Using a seat belt extender
Observe the following precautions to
reduce the risk of in jury in the event of
sudden braking, sudden swerving or an
accident.
Failure to do so may cause death or seri-
ous injury.
●Do not wear the seat belt extender if
you can fasten the seat belt without the
extender.
●Do not use the seat belt extender
when installing a child restraint system
because the belt will not securely hold
the child restraint system, increasing
the risk of death or serious injury in the
event of an accident.
●The personalized extender may not be
safe on another vehi cle, when used by
another person, or at a different seat-
ing position other than the one origi-
nally intended.

261-1. For safe use
1To fasten the seat belt, push the
plate into the buckle until a click
sound is heard.
2 To release the seat belt, press the
release button .
■Emergency locking retractor (ELR)
The retractor will lock the belt during a sud-
den stop or on impact. It may also lock if you
lean forward too quickly. A slow, easy
motion will allow the belt to extend so that
you can move around fully.
■Automatic locking retractor (ALR)
When a passenger’s shoulder belt is com-
pletely extended and then retracted even
slightly, the belt is lock ed in that position and
cannot be extended. This feature is used to
hold a child restraint system (CRS) firmly. To
free the belt again, fully retract the belt and
then pull the belt out once more. ( P.41)
■After the rear center seat belt has been
used
Stow the buckle as shown.
1 Push the seat belt shoulder anchor
down while pressing the release
button .
2 Push the seat belt shoulder anchor
up.
Move the height adjuster up and down as
needed until you hear a click.
NOTICE
■When using a seat belt extender
When releasing the se at belt, press on
the buckle release button on the
extender, not on the seat belt.
This helps prevent damage to the vehicle
interior and the extender itself.

WARNING
■Adjustable shoulder anchor
Always make sure the shoulder belt is
positioned across the center of your
shoulder. The belt should be kept away
from your neck, but not falling off your
shoulder. Failure to do so could reduce
the amount of protection in an accident
and cause death or serious injuries in the
event of a sudden stop, sudden swerve or
accident.

WARNING
■SRS airbag precautions
Observe the following precautions
regarding the SRS airbags.
Failure to do so may cause death or seri-
ous 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 (NHT SA) advises: Since
the risk zone for the dr iver’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
drivers 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-slip pery cushion, or
raise the seat if your vehicle has that
feature.
• If your steering wheel is adjustable, tilt it downward. This points the airbag
toward your chest instead of your head
and neck.
The seat should be adjusted as recom-
mended by NHTSA above, while still
maintaining control of the foot pedals,
steering wheel, and your view of the
instrument panel controls.
●If the seat belt extender has been con-
nected to the front seat belt buckles
but the seat belt extender has not also
been fastened to the latch plate of the
seat belt, the SRS front airbags will
judge that the driver and front passen-
ger are wearing the seat belt even
though the seat belt has not been con-
nected. In this case, the SRS front
airbags may not activate correctly in a
collision, resulting in death or serious
injury in the event of a collision. Be
sure to wear the seat belt with the seat
belt extender.
●The SRS front passenger airbag also
deploys with consid erable force, and
can cause death or serious injury
especially if the front passenger is very
close to the airbag. The front passen-
ger 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
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 seats of the vehicle and properly
restrained. The rear seats are safer for
infants and children than the front pas-
senger seat. (
P.41)

341-1. For safe use
WARNING
●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 airbag 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 pil-
lars.
●Do not allow anyone to kneel on the
passenger seats toward the door or
put their head or hands outside the
vehicle.
●Do not attach anything to or lean any-
thing against areas such as the dash-
board, steering wheel pad and lower
portion of the instrument panel.
These items can become projectiles
when the SRS driver, front passenger
and knee airbags deploy.
●Do not attach anything to areas such
as a door, windshie ld, side windows,
front or rear pillar, roof side rail and
assist grip.
●Do not hang coat hangers or other
hard objects on the coat hooks. All of
these items could become projectiles
and may cause death or serious injury,
should the SRS curtain shield airbags
deploy.
