Installation of an RF-transmitter system
The installation of an RF-transmitter system in your vehicle could affect
electronic systems such as:
Multiport fuel injection system/sequential multiport fuel injection system
Cruise control system
Dynamic radar cruise control system
Anti-lock brake system
SRS airbag system
Seat belt pretensioner system
Be sure to check with any authorized Lexus dealer or repairer, or another

Scrapping 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 any authorized
Lexus dealer or repairer, or another duly qualified and equipped profes-
sional, before you scrap your vehicle.

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 shoul-
der belt, increasing the risk of death or serious injury in the event of an acci-
dent.

Seat belt pretensioners
The pretensioner helps the seat
belt to quickly restrain the
occupant by retracting the seat
belt when the vehicle is sub-
jected to certain types of severe
frontal collision.
The pretensioner may not acti-
vate in the event of a minor
frontal impact, a side impact or
a rear impact.
Pre-crash seat belts (front seats of vehicles with pre-crash safety sys-
tem)
If the pre-crash sensor detects that a collision is unavoidable, the
pre-crash safety system will retract the seat belt, thus enhancing
the effectiveness of the seat belt pretensioner in a crash.
The same will happen if the driver makes an emergency braking or
loses control of the vehicle. (P. 2 1 1 )
Emergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on impact. It may
also lock if you lean forward or pull out the belt too quickly. Allow the belt
to fully retract, and then slowly extend the belt. If the belt cannot be pulled
out of the retractor, firmly pull the belt and release it. You will then be able
to smoothly pull the belt out of the retractor.
