CAUTION
■Seat belt damage and wear
●Do not damage the seat belts by allowing the belt, plate or buckle to be jammed
in the door.
●Inspect the seat belt system periodically. 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.
●Ensure that the belt and plate are locked and the belt is not twisted.
If the seat belt does not function correctly, 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 a seat belts.
Have any necessary repairs carried out by your Lexus dealer. Inappropriate han-
dling of the pretensioner may prevent it from operating properly, resulting in
death or serious injury.
■Precaution for pre-collision seat belts
Do not rely on the pre-collision system to avoid accidents. Always pay attention to
the surrounding conditions, and drive safely and responsibly.

CAUTION
■Using a seat belt extender
●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 a accident.
●The personalized extender may not be safe on another vehicle, when used by
another person, or at a different seating position other than the one originally
intended.
NOTICE
■When using a seat belt extender
When releasing the seat 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.

■The steering wheel can be adjusted when
The “ENGINE START STOP” switch is in ACCESSORY or IGNITION ON
mode
*.
*: If the driver’s seat belt is fastened, the steering wheel can be adjusted regardless of “ENGINE START STOP” switch mode.
■Automatic adjustment of the steering position
A desired steering position can be entered to memory and recalled automatically
by the driving position memory system. ( →P. 7 9 )
CAUTION
■Caution while driving
Do not adjust the steering wheel while driving.
Doing so may cause the driver to mishandle the vehicle and cause an accident,
resulting in death or serious injury.

1-7. Safety information
Correct driving posture
Drive with a good posture as follows:
Sit upright and well back in
the seat. (→P. 6 4 )
Adjust the position of the seat
forward or backward to
ensure the pedals can be
reached and easily
depressed to the extent
required. ( →P. 6 4 )
Adjust the seatback so that
the controls are easily opera-
ble.
Adjust the tilt and telescopic
positions of the steering
wheel downward so the air-
bag is facing your chest.
(→ P. 9 4 )
Lock the head restraint in
place with the center of the
head restraint closest to the
top of your ears. ( →P. 8 3 )
Wear the seat belt correctly.
(→ P. 8 6 )

CAUTION
■While driving
●Do not adjust the position of the driver’s seat.
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
effectiveness of the seat belt and head restraint, increasing the risk of death or
serious injury to the driver or passenger.
●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, resulting in
death or serious injury. The adjustment mechanism may also be damaged.
■Adjusting the seat position
●Take care when adjusting the seat position to ensure that other passengers are
not injured by the moving seat.
●Do not put your hands under the seat or near the moving parts to avoid injury.
Fingers or hands may become jammed in the seat mechanism.

SRS airbags
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 front airbags
SRS driver airbag/front passenger airbag
Can help protect the head and chest of the driver and front passen-
ger from impact with interior components
SRS knee airbags
Can help provide driver and front passenger protection

1-7. Safety information
GX460_CANADA (OM60F29U)Your vehicle is equipped with ADVANCED AIRBAGS designed based
on the US motor vehicle safety standards (FMVSS208). The airbag sys-
tem controls airbag deployment power for the driver and front passen-
ger. The driver airbag system consists of the driver’s seat belt buckle
switch etc. The front passenger’s airbag system consists of the front pas-
senger occupant classification sensor etc.
The main SRS airbag system components are shown above. The SRS air-
bag system is controlled by the airbag sensor assembly. The airbag sen-
sor assembly consists of a safing sensor and a main sensor.
In certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chem
ical reaction in the inflators quickly
fills the airbags with non-toxic gas to help restrain the motion of the occu-
pants.

■SRS airbag deployment conditions (SRS front airbags)
●The SRS front airbag 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 if the vehicle strikes
an object, such as a parked vehicle or sign pole, which can move or deform on
impact, or if the vehicle is involved in an underride collision (e.g. a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a truck, etc.).
●It is possible that in some collisions where the forward deceleration of the vehi-
cle is very close to the designed threshold level, the SRS front airbags and the
seat belt pretensioners may not activate together.
●The SRS front passenger airbag will not activate if there is no passenger sitting
in the front passenger seat. However, the SRS front passenger airbag may
deploy if luggage is put in the seat, or the seat belt is fastened, even if the seat is
unoccupied. (→P. 1 4 0 )
■SRS airbag deployment conditions (SRS side airbags and curtain shield airbags)
The SRS side and curtain shield airbags will deploy in the event of an impact that
exceeds the set threshold level (the level of force corresponding to the impact force
produced by an approximately 3307 lb. [1500 kg] vehicle colliding with the vehicle
cabin from a direction perpendicular to th e vehicle orientation at an approximately
speed of 12 - 18 mph [20 - 30 km/h]).

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 pedalscomfortably.
• 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-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 recommended by NHTSA above, while still main-
taining control of the foot pedals, steering wheel, and your view of the instrument
panel controls.
