The SRS airbag and seat belt pretensioner devices in your Lexus contain explosive
chemicals. If the vehicle is scrapped with th e 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 retailer or Lexus au thorized repairer, or any reliable repairer
before you scrap your vehicle.

■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 the
seats, the glove box, 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.
●Vehicles with ERA-GLONASS: If the SRS ai rbags deploy, the system is designed to
send an emergency call * to the Public Safety Answer ing Point (PSAP), notifying them
of the vehicle’s location (without needing to push the “SOS” button) and an agent will
attempt to speak with the occupants to ascertain the level of emergency and assistance
required. If the occupants are unable to communicate, the agent automatically treats
the call as an emergency and helps to di spatch the necessary emergency services.
(  P. 435)
* : In some cases, the call cannot be made. ( P. 437)
■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:

■Automatic Collision Notification
If any airbag deploys, the system is designed to automatically call the Public
Safety Answering Point (PSAP).
*
The responding agent receives the vehicle’s
location and attempts to speak with the vehicle occupants to assess the level
of emergency. If the occupants are unable to communicate, the agent auto-
matically treats the call as an emer gency, contacts the nearest emergency
services provider to describe the situation, and requests that assistance be
sent to the location.
* : In some cases, the call cannot be made. ( P. 437)
: If equipped
ERA-GLONASS is a telematics service that uses Global Navigation Satellite
System (GLONASS) data and embedded cellular technology to enable the
following emergency calls to be ma de: Automatic emergency calls (Auto-
matic Collision Notification) and manu al emergency calls (by pressing the
“SOS” button). This service is require d by Eurasian Customs Union Regula-
tions.

■Emergency Assistance Button (“SOS”)
In the event of an emergency, push the “SOS” button to reach the Public
Safety Answering Point (PSAP). The answering agent will determine your
vehicle’s location, assess the emergency, and dispatch the necessary assis-
tance required.
If you accidentally press the “SOS” button, tell the agent that you are not experi-
encing an emergency.
When the engine switch is turned to IGNITION ON mode, the red indicator
light will illuminate for 10 seconds and then the green indicator light will illum i-
nate for 2 seconds, indicating that the system is enabled. The indicator lights indi-
cate the following: ● If the green indicator light illuminates and stays on, the system is enabled.
● If the green indicator light flashes, an emergency call is being made (either
automatically or manually).
● If no indicator lights illuminate, the system is not enabled.
● If the red indicator light illuminates any time other than immediately after the
engine switch is turned to IGNITION ON mode, the system may be malfunc-
tioning or the backup battery may be depleted. Contact any authorized Lexus
retailer or Lexus authorized repairer, or any reliable repairer.
The service life of the backup battery is 3 years or more.

GS350_200t_GS F_OM_OM30F83E_(EE)
NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valves, transmitters and
tire valve caps (vehicles with the tire pressure warning system)
●When removing or fitting the wheels, tires or the tire pressure warning valves and
transmitters, contact any authorized Lexus retailer or Lexus authorized repairer, or
any reliable repairer as the tire pressure warning valves and transmitters may be dam-
aged if not handled correctly.
●Make sure to install the tire valve caps. If the tire valve caps are not installed, water
could enter the tire pressure warning valv es and the tire pressure warning valves
could be bound.
●When replacing tire valve caps, do not use tire valve caps other than those specified.
The cap may become stuck.
■To avoid damage to the tire pressure warning valves and transmitters (vehicles with
the tire pressure warning system)
When a tire is repaired with liquid sealants, the tire pressure warning valve and trans-
mitter may not operate properly. If a liquid sealant is used, contact any authorized
Lexus retailer or Lexus authorized repairer, or any reliable repairer or other qualified
service shop as soon as possible. After use of liquid sealant, make sure to replace the
tire pressure warning valve and transmitte r when repairing or replacing the tire.
(  P. 473)
■Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
These conditions may cause losses in tire inflation pressure, reducing the cushioning
ability of the tires. In addition, driving on rough roads may cause damage to the tires
themselves, as well as the vehicle’s wheels and body.
■Low profile tires (except 225/50R17 tires)
Low profile tires may cause greater damage than usual to the tire wheel when sustain-
ing impact from the road surface. Therefore, pay attention to the following:
●Be sure to use proper tire inflation pressu re. If tires are under-inflated, they may be
damaged more severely.
●Avoid potholes, uneven pavement, curbs an d other road hazards. Failure to do so
may lead to severe tire and wheel damage.
■If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.
