When the engine switch is turned to IGNITION ON mode, the red indicator
light comes on for 2 seconds then turns
off. Afterward, the green indicator light
comes on, indicating that the service is active.
The following indicator light patterns indicate specific system usage conditions:
●Green indicator light on = Active service
●Green indicator light flashing = Safety Connect call in process
●Red indicator light (except at vehicle start-up) = System malfunction (contact
your Lexus dealer)
●No indicator light (off) = Safety Connect service not active
■Automatic Collision Notification
In case of either airbag deployment or severe rear-end collision, the system is
designed to automatically call the re sponse center. The responding agent
receives the vehicle’s location and attempts to speak with the vehicl\
e occu-
pants to assess the level of emergency. If the occupants are unable to commu-
nicate, the agent automatically treats the call as an emergency, contacts the
nearest emergency services provider to describe the situation, and requests
that assistance be sent to the location.
■Stolen Vehicle Location
If your vehicle is stolen, Safety Conn ect can work with local authorities to
assist them in locating and recovering the vehicle. After filing a police report,
call the Safety Connect response ce nter at 1-800-25-LEXUS (1-800-255-
3987) and follow the prompts for Safety Connect to initiate this service.
In addition to assisting law enforcemen t with recovery of a stolen vehicle,
Safety-Connect-equipped vehicle locatio n data may, under certain circum-
stances, be shared with third parties to locate your vehicle. Further informa-
tion is available at Lexus.com.
■Emergency Assistance Button (“SOS”)
In the event of an emergency on the ro ad, push the “SOS” button to reach the
Safety Connect response center. Th e 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 response-center agent that you
are not experiencing an emergency.

GS350_300_GS F_OM_OM30G34U_(U)
WARNING
■Driving to spread the liquid sealant evenly
●Drive the vehicle carefully at a low speed. Be especially careful when turning and cor-
nering.
●If the vehicle does not drive straight or you feel a pull through the steering wheel, stop
the vehicle and check the following:
• Tire condition. The tire may have separated from the wheel.
• Tire inflation pressure. If tire inflation pressure is 19 psi (130 kPa, 1.3 kgf/cm
2 or
bar) or less, the tire may be severely damaged.
NOTICE
■When performing an emergency repair
●Perform the emergency repair without removi ng the nail or screw that has punctured
the tread of the tire. If the object that has punctured the tire is removed, repair by the
emergency tire puncture repair kit may not be possible.
●The repair kit is not waterproof. Make sure that the repair kit is not exposed to water,
such as when it is be ing used in the rain.
●Do not put the repair kit directly onto dusty ground such as sand at the side of the
road. If the repair kit vacuums up dust etc., a malfunction may occur.
■Handling the emergency tire puncture repair kit
●The repair kit power source should be 12 V DC suitable for vehicle use. Do not con-
nect the repair kit to any other source.
●If gasoline splatters on the repair kit, the repair kit may deteriorate. Take care not to
allow gasoline to contact it.
●Store the emergency tire puncture repair kit in the trunk.
The kit may be thrown around during sudden braking and so forth, damaging the kit.
●Store the repair kit in the tr unk out of reach of children.
●Do not disassemble or modify the repair kit. Do not subject parts such as the air pres-
sure indicator to impacts. This may cause a malfunction.
■To avoid damage to the tire pressu re warning valves and transmitters
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 your Lexus dealer or
other qualified service shop as soon as possible. Make sure to replace the tire pressure
warning valve and transmitter when replacing the tire. ( →P. 394)

Vehicle specifications
■Recommendation of the use of low emissions gasoline
Gasolines containing oxygenates such as ethers and ethanol, as well as reformulated
gasolines, are available in some cities. Thes e fuels are typically acceptable for use, pro-
viding they meet other fuel requirements.
Lexus recommends these fuels, since the form ulations allow for reduced vehicle emis-
sions.
■Non-recommendation of the use of blended gasoline
●If you use gasohol in your vehicle, be sure that it has an octane ra ting no lower than 91.
●Lexus does not recommend the use of gasoline containing methanol.
■Non-recommendation of the use of gasoline containing MMT
Some gasoline contains an octane enhancing additive called MMT (Methylcyclopenta-
dienyl Manganese Tricarbonyl).
Lexus does not recommend the use of gasoline that contains MMT. If fuel containing
MMT is used, your emission control system may be adversely affected.
The malfunction indicator lamp on the instru ment cluster may come on. If this happens,
contact your Lexus dealer for service.
■If your engine knocks
●Consult your Lexus dealer.
●You may occasionally notice light knocking for a short time while accelerating or driv-
ing uphill. This is normal and there is no need for concern.
●Use only gasoline containing up to 15% etha-
nol.
DO NOT use any flex-fuel or gasoline that
could contain more than 15% ethanol, includ-
ing from any pump labeled E30, E50, E85
(which are only some examples of fuel con-
taining more than 15% ethanol).DO NOT use gasoline con-
taining more than 15% ethanol.
(30% ethanol)
(50% ethanol)
(85% ethanol)
