Installation of a mobile two-way radio system
As the installation of a mobile two-way radio system in your vehicle could affect
electronic systems such as the multiport fuel injection system/sequential multiport
fuel injection system, cruise control system, anti-lock brake system, SRS airbag sys-
tem and seat belt pretensioner system, be sure to check with your Lexus dealer for
precautionary measures or special instructions regarding installation.
Scrapping of your Lexus
The SRS airbag and seat belt pretensioner devices in your Lexus contain explosive
chemicals. If the vehicle is scrapped with the airbags and seat belt pretensioners left
as they are, this may cause an accident such as fire. Be sure to have the systems of
the SRS airbag and seat belt pretensioner removed and disposed of by a qualified
service shop or by your Lexus dealer before you scrap your vehicle.
Perchlorate Material
Special handling may apply, See www.dtsc.ca.gov/hazardouswaste/perchlorate.
Your vehicle has components that may contain perchlorate. These components may
include airbag, seat belt pretensioners, and wireless remote control batteries.

●Always lock all doors.
●Ensure that all doors are properly closed.
●Do not pull the inside handle of the doors while driving.
The doors may be opened and the passengers are thrown out of the vehicle and it

CAUTION
■Seat adjustment
●Do not recline the seat more than necessary when the vehicle is in motion to
reduce the risk of sliding under the lap belt.
If the seat is too reclined, the lap belt may slide past the hips and apply restraint
forces directly to the abdomen or your neck may contact the shoulder belt,
increasing the risk of death or serious injury in the event of an accident.
●Manual seat only: After adjusting the seat, make sure that the seat is locked in
position.
