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 warning 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 ne ck, 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 re placed. 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 correctly, 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 Lexusauthorized repairer, or any reliable repa irer. Inappropriate handling may lead to
incorrect operation.

The main SRS airbag system components are shown above. The SRS airbag sys-
tem is 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.

WARNING
■SRS airbag precautions
Observe the following precautions regarding the SRS airbags. Failure to do so may cause death or serious injury.
●The driver and all passengers in the vehicl e must wear their seat belts properly. The SRS airbags are supplemental 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 driv er 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 yourdriving 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 drivers can achieve the 250 mm (10 in.) dis- tance, even with the driver seat all the way forward, simply by reclining the back ofthe 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 adjustable, tilt it downward. This points the airbag toward
your chest instead of your head and neck. The seat should be adjusted as recommend ed above, while still maintaining control of the foot pedals, steering wheel, and your view of the instrument panel controls.

WARNING
■When installing a child restraint system
For safety reasons, always install a child rest raint 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.

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 reliable 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 vehicleinspected 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 authorized 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. 462) go off. If there is only a small amount of fuel, the hybrid system may not be able to start.(The standard amount of fuel is about 9.9 L [2 .6 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 asconventional 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 lim ited service life. The lifespan of the hybrid
battery (traction battery) can change in accordance with driving style and driving condi- tions.
■Declaration of conformity
This model conforms to hydrogen emissions according to regulation ECE100 (Battery electric vehicle safety).
WARNING
■High voltage precautions
This vehicle has high voltage DC and AC systems as well as a 12-volt system. DC and
AC high voltage is very dangerous and can cause severe burns and electric shock that may result in death or serious injury.
●Never touch, disassemble, remove or replace the high voltage parts, cables or their
connectors.
●The hybrid system will become hot after starting as the system uses high voltage. Be careful of both the high voltage and the hi gh temperature, and always obey the warn-
ing labels attached to the vehicle.
●Never try to open the service plug access
hole located behind the rear seats. The ser- vice plug is used only when the vehicle is ser-viced and is subject to high voltage.
