Observe the following precautions.
Failure to do so may cause the driver’s floor mat to slip, possibly interfering with the ped-
als while driving. An unexpect edly high speed may result or it may become difficult to
stop the vehicle. This could lead to an acc ident, resulting in death or serious injury.
■When installing the driver’s floor mat
●Do not use floor mats designed for other models or different model year vehicles,
even if they are Lexus Genuine floor mats.
●Only use floor mats designed for the driver’s seat.
●Always install the floor mat securely using the retaining hooks (clips) provided.
●Do not use two or more floor mats on top of each other.
●Do not place the floor mat bottom-side up or upside-down.
■Before driving
●Check that the floor mat is securely fixed in
the correct place with all the provided retain-
ing hooks (clips). Be especially careful to per-
form this check after cleaning the floor.
●With the hybrid system stopped and the shift
lever in P, fully depress each pedal to the floor
to make sure it does not interfere with the
floor mat.

Observe the following precautions.
Failure to do so may result in death or serious injury.
●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 posture from being achieved, and reduce the effec-
tiveness of the seat belt and head restraint.
●Do not place anything under the front seats.
Objects placed under the front seats may be come jammed in the seat tracks and stop
the seat from locking in place. This may lead to an accident and the adjustment mech-
anism 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 drivin g, do not force yourself to continue driving
and take a break immediately.

Push the seat belt shoulder anchor
down while pressing the release but-
ton.
Push the seat belt shoulder anchor
up.
Move the height adjuster up and down
as needed until you hear a click.
For children or smaller-than-average
people, slide the seat belt comfort
guide forward so that the shoulder belt
does not sit close to the person’s neck.
The pretensioner helps the seat belt to
quickly restrain the occupant by
retracting the seat belt when the vehi-
cle is subjected to certain types of
severe frontal collision.
The front seat pretensioners also acti-
vate when the vehicle is subjected to
certain types of severe side collision.
The pretensioner does not activate in the event of a minor frontal impact, a minor side
impact, a rear impact or a vehicle rollover.

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 serious 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, including 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 necessary. 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. 3 8 )
Women who are pregnant should position 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 avoiding 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 collision.

impact with interior components
SRS knee airbags
Can help provide driver and front passenger protection
An SRS knee airbag for the front passenger’s seat is built into the glove box door.
◆SRS side and curtain shield airbagsSRS front side airbags
Can help protect the torso of the front seat occupants
SRS rear side airbags
Can help protect the torso of oc cupants in the rear outer seats
SRS curtain shield airbags
Can help protect primarily the head of occupants in the outer seats
The SRS airbags inflate when the vehicle is subjected to certain types of
severe impacts that may cause significant injury to the occupants. They work
together with the seat belts to help reduce the risk of death or serious injury.

■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 seri-
ous injury especially if the driver is very close to the airbag.
Since the risk zone for the driver’s airbag is the first 50 - 75 mm (2 - 3 in.) of inflation,
placing yourself 250 mm (10 in.) 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 250 mm (10 in.) 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 com-
fortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many drivers can achieve the 250 mm (10 in.) dis-
tance, even with the driver seat all the wa y 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, tilt it downward. This points the airbag toward
your chest instead of your head and neck.
The seat should be adjusted as recommend ed above, while still maintaining control
of the foot pedals, steering wheel, and yo ur view of the instrument panel controls.
