CAUTION
■SRS airbag precautions
●Do not hang coat hangers or 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.
●If a vinyl cover is put on the area where the SRS knee airbag will deploy, be sure to
remove it.
●Do not use seat accessories which cover the parts where the SRS side airbags inflate
as they may interfere with inflation of the airbags. Such accessories may prevent the
side airbags from activating correctly, disable the system or cause the side airbags to
inflate accidentally, resulting in death or serious injury.
●Do not allow anyone to kneel on the passen-
ger seats toward the door or put their head or
hands outside the vehicle.
●Do not attach anything to or lean anything
against areas such as the dashboard, steering
wheel pad and lower portion of the instru-
ment 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,
windshield glass, side door glass, front or rear
pillar, roof side rail and assist grip. (Except for
the speed limit sticker →P. 5 1 0 )

When the sensors located at the back of the front bumper detect an impact with
a body, such as a pedestrian, which meets or exceeds the threshold level while
the vehicle is being driven within the operational speed range, the system
becomes operational and raises the rear portion of the hood.
Sensors
Hood
Lifters
Pop Up Hood
In the event of a frontal collision with a body, such as a pedestrian, the Pop Up
Hood system raises the rear portion of the hood to reduce the possibility of a
serious impact to the pedestrian’s head area by adding clearance to the
engine compartment.

The Pop Up Hood will operate when the vehicle detects an impact such as the
following:
●The front bumper detects a frontal impact equivalent to or greater than that of
a pedestrian while the vehicle being driven within the operational speed range
of approximately 25 to 55 km/h (16 to 34 mph). (The system is operated by
an impact of threshold level or greater, even in the case of a minor collision
that may not leave a trace on the front bumper. Also, depending on the impact
conditions or vehicle speed, the system may be operated by a collision with a
light or small object or a small animal.)
●In other situations the system may operate when an impact is applied to the
lower part of the vehicle or front bumper, such as the following:
• Colliding with a curb
• Falling into a deep hole
•Landing hard
• Hitting the slope of a parking lot, an undulating road, a protruding object or
falling object
Pop Up Hood operational conditions
CAUTION
■When the Pop Up Hood is operated
●Do not pull the hood lock release lever. Doing so after the Pop Up Hood has oper-
ated will further raise the hood and may cause an injury.
Do not drive with the hood raised, as doing so may block the driver’s vision, possibly
causing an accident.
Do not forcibly push down the hood. As the popped up hood cannot be lowered by
hand, doing so may deform the hood or cause an injury.
If the Pop Up Hood has operated, have the vehicle inspected by any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional. If the
Pop Up Hood has operated, stop the vehicle in a safe place and contact authorized
Lexus dealer or repairer, or another duly qualified and equipped professional.
●Do not touch the lifters immediately after the Pop Up Hood has operated, as the lift-
ers may be hot and burn you.

CAUTION
■When installing a child restraint system
Follow the directions given in the child restraint system installation manual and fix the
child restraint system securely in place.
If the child restraint system is not correctly fixed in place, the child or other passengers
may be seriously injured or even killed in the event of a sudden braking, sudden swerv-
ing 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 (left-hand
drive vehicles) or the left-hand rear seat
(right-hand drive vehicles).
●Adjust the front passenger seat so that it does
not interfere with the child restraint system.
●When installing a forward-facing child
restraint system on the front passenger seat,
move the seat as far back as possible.
Failure to do so may result in death or serious
injury if the airbags deploy (inflate).

■Tilt sensor detection considerations (if equipped)
The sensor may trigger the alarm in the following situations:
●The vehicle is transported by a ferry, trailer, train, etc.
●The vehicle is parked in a parking garage.
●The vehicle is inside a car wash that moves the vehicle.
●Any of the tires loses air pressure.
●The vehicle is jacked up.
●An earthquake occurs or the road caves in.
NOTICE
■To ensure the intrusion sensor function correctly
●Installing accessories other than genuine Lexus parts or leaving objects between the
driver’s seat and front passenger’s seat may reduce the detection performance.
●To ensure that the sensors operate properly,
do not touch or cover them.
●Do not spray air fresheners or other products
directly into the sensor holes.
