Safety Connect LED light Indicators
When the “ENGINE START STOP” 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 con-
ditions:
●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
Safety Connect services
■Automatic Collision Notification
In case of either airbag deployment or severe rear-end collision, the
system is designed to automatically call the response center. 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 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.

Safety information for Safety Connect
Important! Read this information before using Safety Connect.
■Exposure to radio frequency signals
The Safety Connect system installed in your vehicle is a low-power
radio transmitter and receiver. It receives and also sends out radio fre-
quency (RF) signals.
In August 1996, the Federal Communications Commission (FCC)
adopted RF exposure guidelines with safety levels for mobile wireless
phones. Those guidelines are consistent with the safety standards pre-
viously set by the following U.S. and international standards bodies.
●ANSI (American National Standards Institute) C95.1 [1992]
●NCRP (National Council on Radiation Protection and Measure-
ment) Report 86 [1986]
●ICNIRP (International Commission on Non-Ionizing Radiation Pro-
tection) [1996]
Those standards were based on comprehensive and periodic evalua-
tions of the relevant scientific literature. Over 120 scientists, engineers,
and physicians from universities, and government health agencies and
industries reviewed the available body of research to develop the
ANSI Standard (C95.1).
The design of Safety Connect complies with the FCC guidelines in
addition to those standards.

Maintenance and care
■Bumpers
Do not scrub with abrasive cleaners.
■To prevent deterioration and body corrosion
●Wash the vehicle immediately in the following cases:
• After driving near the sea coast
• After driving on salted roads
• If you see coal tar or tree sap on the paint surface
• If you see dead insects, insect droppings or bird droppings on the paint
• After driving in an area contaminated with soot, oily smoke, mine dust, iron
powder or chemical substances
• If the vehicle becomes heavily soiled in dust or mud
• If liquids such as benzene and gasoline are spilled on the paint surface
●If the paint is chipped or scratched, have it repaired immediately.
CAUTION
■Exhaust pipes and rear bumper exhaust diffusers
Exhaust gasses cause the exhaust pipes and rear bumper exhaust diffusers to
become quite hot. Therefore, do not touch them while the engine is running or
immediately after turning the engine off.
When washing the vehicle, be careful not to touch the exhaust pipes and rear
bumper exhaust diffusers until they have cooled sufficiently, as touching hot exhaust
pipes and diffusers can cause burns.

Maintenance and care
■Allow inspection and repairs to be performed by a Lexus dealer
●Lexus technicians are well-trained specialists and are kept up to date with the
latest service information. They are well informed about the operations of all
systems on your vehicle.
●Keep a copy of the repair order. It proves that the maintenance that has been
performed is under warranty coverage. If any problem should arise while your
vehicle is under warranty, your Lexus dealer will promptly take care of it.
CAUTION
■If your vehicle is not properly maintained
It could result in serious damage to the vehicle and possible serious injury or death.
■Warning in handling of battery
●Engine exhaust, some of its constituents, and a wide variety of automobile com-
ponents contain or emit chemicals known to the State of California to cause can-
cer and birth defects and other reproductive harm. Work in a well ventilated area.
●Oils, fuels and fluids contained in vehicles as well as waste produced by compo-
nent wear contain or emit chemicals known to the State of California to cause
cancer and birth defects or other reproductive harm. Avoid exposure and wash
any affected area immediately.
●Battery posts, terminals and related accessories contain lead and lead com-
pounds which are known to cause brain damage. Wash your hands after han-
dling. (P. 3 8 2 )
