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 deal er 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.

1-7. Safety information
In certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chemica l reaction in the inflators quickly
fills the airbags with non-toxic gas to he lp restrain the motion of the occu-
pants.
■SRS warning light
This warning light system monitors the airb ag sensor assembly, front airbag sensors,
side airbag sensor assemblies , driver's seat position sensor, driver's seat belt buckle
switch, seat belt pretensioner assemblies, inflators, interconnecting wiring and
power sources. ( P. 4 7 0 )
■If the SRS airbags deploy (inflate)
●Bruising and slight abrasion s may result from contact with a deploying (inflating)
SRS airbag.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel , airbag cover and inflator) as well as
the front seats may be hot for several minu tes. The airbag itself may also be hot.
●The windshield may crack.
●For Safety Connect subscribers, if the SRS airbags deploy or in the event of a
severe rear-end collision, the system is designed to send an emergency call to
the response center, 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 emer-
gency and helps to dispatch the necessary emergency services. ( P. 3 7 2 )

2-5. Driving information
Winter driving tips
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate to the
prevailing weather conditions.
■ Pre-winter preparations
●Use fluids that are appropria te to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the level and specific gravity of
battery electrolyte.
● Have the vehicle fitted with four snow tires or purchase a set of
tire chains for the rear tires.
Ensure that all tires are the specified size and the same brand, and that
chains match the size of the tires.
■ Before driving the vehicle

front of the windshield.
