When the engine switch is turned to IGNITION ON mode, the red indi-
cator 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
■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 occu-
pants are unable to communicate, the agent automatically treats the
call as an emergency, contacts the nearest emergency services pro-
vider to describe the situation, and requests that assistance be sent to
the location.

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 previ-
ously 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.

6-1. Maintenance and care
CAUTION
■When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may cause
the electrical components etc. to catch fire.
■When cleaning the windshield (with rain-sensing windshield wipers)
●When the upper part of the windshield where the raindrop sensor is located is
touched by hand
●When a wet rag or similar is held close to the raindrop sensor
●If something bumps against the windshield
●If you directly touch the raindrop sensor body or if something bumps into the
raindrop sensor
■Precautions regarding the exhaust pipes and rear bumper diffusers
Exhaust gases cause the exhaust pipes and rear bumper diffusers to become quite
hot.
When washing the vehicle, be careful not to touch the pipes and diffusers until they
have cooled sufficiently, as touching hot exhaust pipes and rear bumper diffusers
can cause burns.
Set the wipers to the intermittent windshield
wipers. ( →P. 200)
If AUTO mode is selected, the wipers may
operate unexpectedly in the following situa-
tions, and may result in hands being caught
or other serious injuries and cause damage
to the wiper blades.

6-2. Maintenance
■Repair and replacement
It is recommended that genuine Lexus parts be used for repairs to ensure perfor-
mance of each system. If non-Lexus parts are used in replacement or if a repair shop
other than a Lexus dealer performs repairs, confirm the warranty coverage.
■Reset the maintenance data (U.S.A. only)
After the required maintenance is performed according to the maintenance sched-
ule, please reset the maintenance data.
To reset the data, follow the procedure described below:Switch the display to the trip meter “A” ( →P. 80) when the engine is running.
Turn the engine switch off.
While pressing the “ODO TRIP” button ( →P. 80), turn the engine switch to the
IGNITION ON mode (do not start the engine because otherwise the reset mode
will be canceled).
■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 per-
formed is under warranty coverage. If any problem should arise while your vehicle
is under warranty, your Lexus dealer will promptly take care of it. The message shown in the illustration will
appear on the display.
Continue to press and hold the button until
the trip meter displays “000000”.
