WARNING
Observe the following precautions to reduce the risk of injury in the event of sudden braking, sudden swerving or an accident.Failure to do so may cause death or serious injury.
■Wearing a seat belt
●Ensure that all passengers wear a seat belt.
●Always wear a seat belt properly.
●Each seat belt should be used by one pe rson only. Do not use a seat belt for more than one person at on ce, including children.
●Lexus recommends that children be seated in the rear seat and always use a seat belt
and/or an appropriate child restraint system.
●To achieve a proper seating position, do no t recline the seat more than necessary. The seat belt is most effective when the occupants are sitting up straight and well back in
the seats.
●Do not wear the shoulder belt under your arm.
●Always wear your seat belt low and snug across your hips.
■Pregnant women
Obtain medical advice and wear the seat belt
in the proper way. ( P. 38)
Women who are pregnant should position the lap belt as low as possible over the hips in the
same manner as other occupants, extending the shoulder belt completely over the shoulderand avoiding belt contact with the rounding of
the abdominal area.
If the seat belt is not worn properly, not only the pregnant woman, but also the fetus could suffer
death or serious injury as a result of sudden braking or a collision.

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 unfastened, scissors should be used to cut the
belt.
■Seat belt pretensioners
If the pretensioner has activated, the SRS warn ing light will come on. In that case, the
seat belt cannot be used again and must be replaced at any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.
■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 dealer or repairer, or another duly qualified and equipped professional.
●Replace the seat assembly, incl uding 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 dealer or repairer,
or another duly qualified and equipped professional. Inappropriate handling may lead to incorrect operation.
■When using the seat belt guide
●Always make sure that the belt is not twisted, and runs freely through the guide.
●Regardless of whether the guide is used or not, always secure the seat belt guide but-ton.
●Do not hang from or pull the guide forcefully.

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 chemical 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 non-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. 56)
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 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
■SRS airbag precautions
●The SRS front passenger airbag also deploys with considerable force, and can cause death or serious injury especially if the fron t passenger is very close to the airbag. The
front passenger seat should be as far from the airbag as possible with the seatback adjusted, so the front passenger sits upright.
●Improperly seated and/or restrained infant s 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 recom- mends that all infants and children be placed in the rear seats of the vehicle and prop-
erly restrained. The rear seats are safer for infants and children than the front passenger seat. ( P. 60)
●Do not sit on the edge of the seat or lean against the dashboard.
●Do not allow a child to stand in front of theSRS 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 railor the front, side and rear pillars.

■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 thefront 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.
■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 wall that does not move or deform).
However, this threshold velocity will be cons iderably 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 possib le that only the seat belt pretensioners will
activate.
■SRS airbag deployment conditions (SRS side and curtain shield airbags)
●The SRS side and curtain shield airbags w ill 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 vehiclecabin from a direction perpendicular to the vehicle orientation at an approximate
sp ee d o f 20 - 30 km/h [12 - 18 mph]).
●The SRS side and curtain shield airbags will de ploy in the event of a severe frontal colli- sion.

●It is recommended that children sit in the rear seats to avoid accidental con-
tact with the shift lever, wiper switch, etc.
●Use the window lock switch to avoid children 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 wea r the vehicle’s seat belt.
WARNING
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 sh ift the vehicle into neutral. There is also a danger that children may injure themselves by playing with the windows, the moon roof or other features of the vehicle. In addition, heat build-up or extremely cold tempera-
tures inside the vehicle can be fatal to children.

WARNING
■When a child is riding
Observe the following precautions. Failure to do so may result in death or serious injury.
●For effective protection in automobile accidents and sudden stops, a child must be properly restrained, using a seat belt or child restraint system depending on the age and size of the child.
●Lexus strongly urges the use of a proper child restraint system that conforms to thesize of the child, installed on the rear seat. According to accident statistics, the child is safer when properly restrained in the rear seat than in the front seat.
●Holding a child in your or someone else’s ar ms is not a substitute for a child restraint system. In an accident, the child can be crushed against the windshield or betweenthe holder and the interior of the vehicle.
●Place one child to a child restraint system and then secure the child with the harnessof the child restraint system.
■Handling the child restraint system
If the child restraint system is not properly fixed in place, the child or other passengers may be seriously injured or even killed in the event of sudden braking, sudden swerv- ing, or an accident.
●If the vehicle were to receive a strong impact from an accident, etc., it is possible thatthe child restraint system has damage that is not readily visible. In such cases, do notreuse the restraint system.
●Depending on the child restrain t system, installation may be difficult or impossible. In those cases, check whether the child restraint system is suitable for installment in the vehicle. ( P. 68, 75) Be sure to install and observe the usage rules after carefully
reading the child restraint system fixing me thod in this manual, as well as the opera- tion manual enclosed with the child restraint system.
●Keep the child restraint system properly secure d on the seat even if it is not in use. Do
not store the child restraint system un secured in the passenger compartment.
●If it is necessary to detach the child restraint system, remove it from the vehicle or store it securely in the trunk.
