■If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may be sustained from SRS airbags, due to the
extremely high speed deployment (inflation) by hot gases.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel hub, airbag cover and inflator) as well as the
front seats, parts of the front and rear pillars, and roof side rails, may be hot for several minutes. The airbag itself may also be hot.
●The windshield may crack.
●Vehicles with ERA-GLONASS: If the SRS airbags deploy, the system is designed tosend an emergency call* to the Public Safety Answering Point (PSAP), notifying them
of the vehicle’s location (without needing to push the “SOS” button) and an agent will
attempt to speak with the occupants to asce rtain the level of emergency and assistance required. If the occupants are unable to communicate, the agent automatically treats
the call as an emergency and helps to dispatch the necessary emergency services.
( P. 496)
*: In some cases, the call cannot be made. (P. 498)
■SRS airbag deployment conditions (SRS front airbags)
●The SRS front airbags will deploy in the event of an impact that exceeds the set thresh-
old level (the level of force corresponding to an approximately 20 - 30 km/h [12 - 18 mph] frontal collision with a fixed wa ll that does not move or deform).
However, this threshold veloci ty will be considerably higher in the following situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which can move or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in which the
front of the vehicle “underrides”, or goes under, the bed of a truck
●Depending on the type of collision, it is possible that only the seat belt pretensioners will
activate.
■SRS airbag deployment conditions (S RS side 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 1500 kg [3300 lb.] vehicle colliding with the vehicle
cabin from a direction perpendicular to th e vehicle orientation at an approximate
speed of 20 - 30 km/h [12 - 18 mph]).
●The SRS curtain shield airbags will deploy in the event of a severe frontal collision.

■“PASSENGER AIR BAG” indicator information
If any of the following problems occur, it is possible that there is a malfunction in the sys-
tem. Have the vehicle inspected by any au thorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
●Neither “ON” nor “OFF” comes on.
●The indicator light does not change when th e airbag manual on-off switch is switched to “ON” or “OFF”.
WARNING
■When installing a child restraint system
For safety reasons, always inst all 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 seriou s 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.

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 driv en 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 fron t 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 oper ate 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
WARNING
■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 h ood and may cause an injury. Do not drive with the hood raised, as doin g 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 th e hood or cause an injury.
If the Pop Up Hood has operated, have the vehicle inspected by any authorized
Lexus retailer or Lexus author ized repairer, or any reliable repairer. If the Pop Up Hood has operated, stop the vehicle in a sa fe place and contact any authorized Lexus
retailer or Lexus authorized repa irer, or any reliable repairer.
●Do not touch the lifters immediately after the Pop Up Hood has operated, as the lift- ers may be hot and burn you.

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 precautions.
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 vehicle even when the trunk lid is closed, open the windows and have the vehicle inspected at any authorized Lexus retailer or Lexus
authorized repairer, or any reliab le repairer as soon as possible.
■When parking
●If the vehicle is in a poorly ventilated area or a closed area, such as a garage, stop the
hybrid system.
●Do not leave the vehicle with the hybrid system on 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 hybrid system operating in an area with snow build-up, or where it is snowing. If snowbanks build up around the vehicle while the hybrid system is operat-
ing, exhaust gases may collect and enter the vehicle.
■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 Le xus retailer or Lexus authorized repairer, or any reliable repairer.

■If a warning light comes on, a warning message is displayed, or the 12-volt battery is dis-
connected
The hybrid system may not start. In this case, try to start the system again. If the “READY” indicator does not come on, contact any au thorized Lexus retailer or Lexus authorized
repairer, or any reliable repairer.
■Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started, refuel the
vehicle with at least enough gasoline to make the low fuel level warning light (P. 577)
go off. If there is only a smal l amount of fuel, the hybrid system may not be able to start. (The standard amount of fuel is about 10 L [2.7 gal., 2.2 Imp. gal.], when the vehicle is on
a level surface. This value may vary when the vehicle is on a slope. Add extra fuel when
the vehicle is inclined.)
■Electromagnetic waves
●High voltage parts and cables on hybrid ve hicles incorporate electromagnetic shield-
ing, and therefore emit approximately the same amount of electromagnetic waves as conventional gasoline powered vehicles or home electronic appliances.
●Your vehicle may cause sound interference in some third party-produced radio parts.
■Hybrid battery (traction battery)
The hybrid battery (traction battery) has a li mited service life. The lifespan of the hybrid
battery (traction battery) can change in acco rdance with driving style and driving condi-
tions.
■Declaration of conformity
This model conforms to hydrogen emission s according to regulation ECE100 (Battery
electric vehicle safety).

indicate that the system is operating.
The indicator light stops flashing after
the power switch has been turned to
ACCESSORY or ON mode to indi-
cate that the system has been canceled.
■System maintenance
The vehicle has a maintenance-fr ee type immobilizer system.
■Conditions that may cause the system to malfunction
●If the grip portion of the key is in contact with a metallic object
●If the key is in close proximity to or touching a key registered to the security system (key
with a built-in transponde r chip) of another vehicle
Immobilizer system
The vehicle’s keys have built-in transponder chips that prevent the hybrid sys-
tem from starting if a key has not been previously registered in the vehicle’s
on-board computer.
Never leave the keys inside the ve hicle when you leave the vehicle.
This system is designed to help prev ent vehicle theft but does not guarantee
absolute security against all vehicle thefts.

●Places with extreme vibrations or noises, or situations in which the vehicle is subject to
repeated impacts or vibrations:
• When parked in a parking garage
• When the vehicle is transported on a ferry, trailer, train, etc.
• When ice adhering to the vehicle is removed • When the vehicle is in an auto matic or high-pressure car wash
• When in a hail or lightning storm
●A window or the moon roof is open.
In this case, the sensor may detect the follow- ing:
• Wind or the movement of objects such as
leaves and insects inside the vehicle • Ultrasonic waves emitted from devices
such as the intrusion sensors of other vehi-
cles • The movement of peop le outside the vehi-
cle
●Unstable items, such as dangling accessories
or clothes hanging on the coat hooks, are in the vehicle.
