Types of collisions that may not deploy the SRS airbags (SRS side and curtain
shield airbags)
The SRS side and curtain shield airbags may not activate if the vehicle is sub-
jected to a collision from the side at certain angles, or a collision to the side of the
vehicle body other than the passenger compartment.
The SRS side airbags do not generally inflate if the vehicle is involved in a fron-
tal or rear collision, if it rolls over, or if it is involved in a low-speed side colli-
sion.
The SRS curtain shield airbags do not generally inflate if the vehicle is involved
in a rear collision, if it rolls over, or if it is involved in a low-speed side or low-
speed frontal collision.

“PASSENGER AIR BAG” indicator information
If any of the following problems occur, it is possible that there is a malfunction in
the system. Have the vehicle inspected by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
Neither “ON” nor “OFF” comes on.
The indicator light does not change when the airbag manual on-off switch is
switched to “ON” or “OFF”.
CAUTION
When installing a child restraint system
For safety reasons, always install a child restraint system in a rear seat. In the
event that the rear seat cannot be used, the front seat can be used as long as the
airbag manual on-off system is set to off.
If the airbag manual on-off system is left on, the strong impact of the airbag
deployment (inflation) may cause serious injury or even death.
When a child restraint system is not installed on the front passenger seat
Ensure that the airbag manual on-off system is set to on.
If it is left off, the airbag may not deploy in the event of an accident, which may
result in serious injury or even death.

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.

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 opera-
tional 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
operated 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 low-
ered 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 autho-
rized Lexus dealer or repairer, or another duly qualified and equipped profes-
sional. If the Pop Up Hood has operated, stop the vehicle in a safe place and
contact any 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 lifters may be hot and burn you.

Pop Up Hood precautions
Before scrapping your vehicle, make sure to contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
The Pop Up Hood system cannot be reused once it has operated. Have it
replaced by any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional.
Conditions under which the Pop Up Hood may not operate properly
The Pop Up Hood may not operate properly under the following conditions:
If a pedestrian collides with the right or left corner of the front bumper or the
side of the vehicle. As such impacts may be difficult to detect, the system may
not operate.
If the vehicle speed is not detected correctly, such as if the vehicle is sliding
sideways, the system may not operate properly.
Conditions under which the Pop Up Hood may not operate
The Pop Up Hood may not operate in the following situations:
Colliding with a lying pedestrian
A frontal impact applied to the front bumper while driving at speeds outside of
the operational speed range
A side impact or rear impact
A vehicle rollover (In some accident situations, the Pop Up Hood may operate.)

NOTICE
Pop Up Hood precautions
Make sure to close the hood before driving, as the system may not operate
properly if the hood is not fully closed.
Make sure that all 4 tires are of the specified size and inflated to the specified
tire pressure (P. 570). If tires of a different size are used, the system may
not operate properly.
If something has hit the area around the front bumper, the sensors may be
damaged even if the Pop Up Hood has not operated. Have the vehicle
inspected by any authorized Lexus dealer or repairer, or another duly quali-
fied and equipped professional.
Do not remove or repair the parts or wiring of the Pop Up Hood, as doing so
may cause accidental operation or prevent the system from operating prop-
erly. If repair or replacement is necessary, contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
Do not remove such components as the front bumper, hood or suspension, or
replace them with non-genuine parts, as doing so may prevent the system
from operating properly.
Do not install anything to the front bumper or hood, as doing so may prevent
the sensors from detecting an impact correctly and prevent the system from
operating properly.
Do not close the hood with force or apply load to the lifters, as doing so may
damage the lifters and prevent the system from operating properly.
Do not modify the suspension, as changes made to the vehicle height may
prevent the system from operating properly.

It is recommended that children sit in the rear seats to avoid accidental
contact with the shift lever, wiper switch etc.
Use the rear door child-protector lock or the window lock switch to
avoid children opening the door while driving or operating the power
window accidentally.
Do not let small children operate equipment which may catch or pinch
body parts, such as the power window, hood, trunk, seats etc.
Safety information for children
Observe the following precautions when children are in the vehicle.
Use a child restraint system appropriate for the child, until the child
becomes large enough to properly wear the vehicle’s seat belt.
CAUTION
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 win-
dows, the moon roof or other features of the vehicle. In addition, heat build-up
or extremely cold temperatures inside the vehicle can be fatal to children.
