WARNING
■SRS airbag precautions
●Do not strike or apply significant levels of force to the area of the SRS airbag compo- nents.
Doing so can cause the SRS airbags to malfunction.
●Do not touch any of the component parts immediately after the SRS airbags have deployed (inflated) as they may be hot.
●If breathing becomes difficult after the SRS airbags have deployed, open a door orwindow to allow fresh air in, or leave the vehicle if it is safe to do so. Wash off any resi-due as soon as possible to prevent skin irritation.
●If the areas where the SRS airbags are stored, such as the steering wheel pad andfront and rear pillar garnishes are damaged or cracked, have them replaced by anyauthorized Lexus dealer or repairer, or an other duly qualified and equipped profes-
sional.
■Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications without
consulting any authorized Lexus dealer or repairer, or another duly qualified and equipped professional. The SRS airbags may malfunction or deploy (inflate) acciden-tally, causing death or serious injury.
●Installation, removal, disassembly and repair of the SRS airbags
●Repairs, modifications, removal or repl acement of the steering wheel, instrument panel, dashboard, seats or seat upholstery, fr ont, side and rear pillars or roof side rails
●Repairs or modifications of the front fender, front bumper, or side of the occupant compartment
●Installation of a grille guard (bull bars, kangaroo bar, etc.), snow plows, winches
●Modifications to the vehicle’s suspension system

■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.

*1: Adjust the front seatback to the most upright position. Move the front seat to the
rearmost position.
If the head restraint interferes with your child restraint system, and the head restraint
can be removed, remove the head restraint. If the passenger seat is equipped with a
vertical height adjuster, it must be placed in the upper most position.
Follow these procedures:
• For installing a baby se at with support base
If the baby seat interferes with the seatback when latching the baby seat into the
support base, adjust the seatback rear ward until there is no interference.
• For installing a forward-facing child seat
If there is gap between the child seat and the seatback, tilt the seatback until good
contact is achieved. If the seat belt should er anchor is ahead of the child seat belt
guide, move the seat cushion forward.
• For installing a junior seat
If the child in your child restraint system is in a very upright position, adjust the
seatback to the most comfortable position.
If the seat belt shoulder anchor is ahead of the child seat belt guide,
move the seat cushion forward.
*2: If the head restraint interferes with your child restraint system, and the head restraint
can be removed, remove the head restraint.
●Adjust the front seat so that it does not interfere with the child or child restraint
system.
●The child restraint systems mentioned in the table may not be available out-
side of the EU area.
●Other child restraint systems which are different from the systems mentioned
