WARNING
■People suffering illness
Obtain medical advice and wear the seat belt in the proper way. (P. 38)
■When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes twisted around a child’s neck, it may lead to choking or othe r serious injuries that could result in death.
If this occurs and the buckle cannot be unfa stened, scissors should be used to cut the
belt.
■Seat belt pretensioners
If the pretensioner has activated, the SRS wa rning light will come on. In that case, the
seat belt cannot be used again and must be replaced at any authorized Lexus retailer or Lexus authorized repairer , or any reliable repairer.
■Adjustable shoulder anchor
Always make sure the shoulder belt is positioned across the center of your shoulder. The belt should be kept away from your neck , but not falling off your shoulder. Failure to
do so could reduce the amount of protection in an accident and cause death or serious
injuries in the event of a sudden stop, sudden swerve or accident. (P. 39)
■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 correctl y, immediately contact any authorized Lexus
retailer or Lexus authorized repa irer, or any reliable repairer.
●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 the seat belts. Have any necessary repairs carried out by any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repa irer. Inappropriate handling may lead to
incorrect operation.

The main SRS airbag system and Pop Up Hood components are shown above.
The SRS airbag system and Pop Up Hood are controlled by the airbag sensor
assembly. As the airbags deploy, a chemi cal reaction in the inflators quickly fills
the airbags with non-toxic gas to help restrain the motion of the occupants.
When the Pop Up Hood is activated, a no n-toxic gas is released due to a chemi-
cal reaction in the lifters, which causes the pistons to eject quickly and raise the
rear portion of the hood. (Pop Up Hood: P. 55)

WARNING
■SRS airbag precautions
Observe the following precaution s 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 supple mental devices to be used with the seat belts.
●The SRS driver airbag deploys with considerable force, and can cause death or seri-
ous injury especially if the driver is very close to the airbag.
Since the risk zone for the driver’s airbag is the first 50 - 75 mm (2 - 3 in.) of inflation,
placing yourself 250 mm (10 in.) 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 250 mm (10 in.) 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 pedals com- fortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many driv ers can achieve the 250 mm (10 in.) dis- tance, even with the driver seat all the wa y 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 ad justable, tilt it downward. This points the airbag toward
your chest instead of your head and neck. The seat should be adjusted as recommen ded above, while still maintaining control
of the foot pedals, steering wheel, and your view of the instrument panel controls.

■“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).
