RX450h_RX450hL _U_OM48F85UWARNING ■
SRS airbag precautions
●
Do not hang coat hangers or other hard obje cts on the coat hooks. All of these items
could become projectiles and may cause deat h or serious injury, should the SRS cur-
tain shield airbags deploy. ●
If a 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 and
SRS seat cushion airbag inflate as they may interfere with inflatio n of the SRS airbags.
Such accessories may prevent the side airbags and SRS seat cushion airbag from
activating correctly, disable the system or cause the side airbags and SRS seat cush-
ion airbag to inflate accidentally, re sulting in death or serious injury.●
Do not strike or apply significant levels of force to the areas around the SRS airbag
components or the front doors.
Doing so can cause the SRS airbags to malfunction. ●
Do not touch any of the component part s immediately after the SRS airbags have
deployed (inflated) as they may be hot. ●
If breathing becomes difficult after the SR S airbags have deployed, open a door or
window to allow fresh air in, or leave the vehicl e 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 and
front and rear pillar garnishes, are damaged or cracked, have them replaced by your
Lexus dealer. ●
Do not place anything, such as a cushion, on the front passenger’s seat. Doing so will
disperse the passenger’s weight, which prevents the sensor from detecting the pas-
senger’s weight properly. As a result, the SRS front airb ags for the front passenger
may not deploy in the event of a collision. ●
Do not attach anything to or lean anything
against areas such as the dashboard, steering
wheel pad and lower po rtion of the instru-
ment panel.
These items can become projectiles when the
SRS driver, front passeng er and knee airbags
deploy. ●
Do not attach anything to areas such as a
door, windshield, side windows, front or rear
pillar, roof side rail and assist grip.
