WARNING
●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.48)
●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 seat toward the door or put their head or hands outside the vehi-cle.
●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.

WARNING
●Do not attach anything to areas such as a door, windshield, side window, front or rear pillar and roof side rail.
●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 curt ain 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 air- bags inflate as they may interfere with inflation of the SRS airbags. Such
accessories may prevent the side air- bags from activating correctly, disable the system or cause the side airbags to
inflate accidentally, resulting in death or serious injury.
●Do not strike or apply significant levels of force to the area of the SRS airbag
components or the doors. Doing so can cause the SRS airbags to malfunction.
●Do not touch any of the component
parts immediately after the SRS air- bags have deployed (inflated) as they may be hot.
●If breathing becomes difficult after the
SRS airbags have deployed, open a door or window to allow fresh air in, or leave the vehicle if it is safe to do so.
Wash off any residue as soon as possi- ble to prevent skin irritation.
●If the areas where the SRS airbags are stored, such as the steering wheel pad
and front and rear pillar garnishes are damaged or cracked, have them replaced by any authorized Lexus
retailer or Lexus authorized repairer, or any reliable repairer.
■Modification and disposal of SRS air-bag system components
Do not dispose of your vehicle or per- form any of the following modifications
without consulting any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer. The SRS airbags
may malfunction or deploy (inflate) acci- dentally, causing death or serious injury.
●Installation, removal, disassembly and repair of the SRS airbags
●Repairs, modifications, removal or
replacement of the steering wheel, instrument panel, dashboard, seats or seat upholstery, front, side and rear pil-
lars, roof side rails, door panels, door trims or door speakers

■Pop Up Hood precautions
●Before scrapping your vehicle, make sure
to contact any authorized Lexus retailer or Lexus authorized repairer, or any reli-able repairer.
●The Pop Up Hood system cannot be reused once it has operated. Have it replaced by any authorized Lexus retailer
or Lexus authorized repairer, or any reli- able repairer.
■Pop Up Hood operational conditions
The Pop Up Hood will operate when the vehicle detects an impact such as the fol-lowing:
●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 le vel 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 condi-tions or vehicle speed, the system may
operate by a collision with a light or small object or a small animal.)
●In other situations, such as the following the system may operate when an impact is applied to the lower part of the vehicle
or front bumper: • 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
■Conditions under which the Pop Up Hood may not operate properly
●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 cor-rectly, such as if the vehicle is sliding side-
ways, the system may not operate properly.
■Conditions under which the Pop Up Hood will not operate
The Pop Up Hood will not operate in the following situations:
●Colliding with a lying person
Pop Up Hood
In the event of a frontal collision
with a body, such as a pedestrian,
the Pop Up Hood system raises the
hood to reduce the possibility of a
serious impact to the pedestrian’s
head area by adding clearance to
the engine compartment.
When the sensors located at the
back of the front bumper detect a
frontal 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 operates.

1-1. For safe use
●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 situ-ations, the Pop Up Hood may operate.)
WARNING
■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 caus-ing 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
it replaced by any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer. If the Pop Up
Hood has operated, stop the vehicle in a safe place and contact authorized Lexus retailer or Lexus authorized
repairer, or any reliable repairer.
●Do not touch the lifters immediately after the Pop Up Hood has operated, as the lifters may be hot and burn you.
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 speci-fied tire pressure. 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
retailer or Lexus authorized repairer, or any reliable repairer.
●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 properly. If repair or replacement is
necessary, contact any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
●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 sys-
tem from operating properly.
●Do not install anything to the front bumper or hood, as doing so may pre-vent the sensors from detecting an
impact correctly and prevent the sys- tem 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 operat-ing properly.

Exhaust gas precautions
Harmful substance to the human
body is included in exhaust gases if
inhaled.
WARNING
Exhaust gases include harmful carbon monoxide (CO), which is colorless and odorless. Observe the following precau-
tions. Failure to do so may cause exhaust gases enter the vehicle and may lead to an
accident caused by light-headedness, or may lead to death or a serious health hazard.
■Important points while driving
●Keep the trunk lid closed.
●If you smell exhaust gases in the vehi-cle even when the trunk lid is closed,
open the windows and have the vehi- cle inspected at any authorized Lexus retailer or Lexus authorized repairer,
or any reliable repairer as soon as pos- sible.
■When parking
●If the vehicle is in a poorly ventilated area or a closed area, such as a garage, stop the engine tem>.
●Do not leave the vehicle with the engine running for a long time.
If such a situation cannot be avoided, park the vehicle in an open space and ensure that exhaust fumes do not enter
the vehicle interior.
●Do not leave the engine running in an area
with snow build-up, or where it is snowing. If snowbanks build up around the vehicle while the engine is running
, exhaust gases may collect and enter the vehi-cle.
■Exhaust pipe
The exhaust system needs to be checked periodically. If there is a hole or crack
caused by corrosion, damage to a joint or abnormal exhaust noise, be sure to have the vehicle inspected and repaired
by any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.

For safety and security
WARNING
■When installing a child restraint sys- tem
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 sys- tem 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.
Riding with children
Observe the following precautions
when children are in the vehicle.
Use a child restraint system appro-
priate for the child, until the child
becomes large enough to properly
wear the vehicle’s seat belt.
 It is recommended that children
sit in the rear seats to avoid acci-
dental contact with the shift lever,
wiper switch, etc.
 Use the window lock switch to
avoid children operating the
power window accidentally.
( P.152)
 Do not let small children operate
equipment which may catch or
pinch body parts, such as the
