Before driving
CAUTION
■SRS airbag precautions
●If the vinyl cover is put on the area where the SRS knee airbag will deploy, be sure
to remove it.
●Do not use seat accessories which cover the parts where the SRS side airbags
inflate as this may interfere with inflation of these airbags.
●Do not strike or apply significant levels of force to the area of the SRS airbag
components shown on P. 61. Doing so could cause a SRS airbag to malfunction.
●Do not touch any of the component parts immediately after the SRS airbag has
deployed (inflated) as they become hot.
●If breathing becomes difficult, open a d oor or window to allow fresh air in, or
leave the vehicle if it is safe to do so. Wash off any residue as soon as possible to
prevent skin irritation.
●If the areas where the SRS airbags are stored, such as the steering wheel pad and
front pillar garnish, are damaged or cracked, have them replaced by your Lexus
dealer.
●Do not attach any heavy, sharp or hard
objects such as keys or accessories to the
ignition key. The obje cts may restrict the
SRS knee airbag inflation or be thrust into
the driver's seat area by the force of the
deploying airbag, thus causing a danger.
