■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 emer-
gency. If the occupants are unable to
communicate, the ag ent automatically
treats the call as an emergency, con-
tacts 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 Connect
can work with local authorities to assist
them in locating and recovering the
vehicle. After filing a police report, call
the Safety Connect response center at
1-800-25-LEXUS (1-800-255-
3987) in the United States, 1-877-
539-8777 in Puerto Rico or 1-800-
265-3987 in Canada, and follow the
prompts for Safety Connect to initiate
this service. In addition to assisting law enforce-
ment with recovery of a stolen vehicle,
Safety-Connect-equipped vehicle
location data may, under certain cir-
cumstances, be shared with third par-
ties to locate your vehicle. Further
information is available at Lexus.com.
■Emergency Assistance Button
(“SOS”)
In the event of an emergency on the
road, push the “SOS” button to reach
the Safety Connect response center.
The answering agent will determine
your vehicle’s location, assess the
emergency, and dispatch the neces-
sary assistance required.
If you accidentally press the “SOS” button,
tell the response-center agent that you are
not experiencing an emergency.
■Enhanced Roadside Assistance

before using Safety Connect;
The Safety Connect system installed in
your vehicle is a low-power radio trans-
mitter and receiver. It receives and also
sends out radio frequency (RF) signals.
In August 1996, the Federal Commu-
nications Commission (FCC) adopted
RF exposure guidelines with safety lev-
els for mobile wireless phones. Those
guidelines are consistent with the
safety standards previously set by the
following U.S. and international stan-
dards bodies.
ANSI (American National Stan-
dards Institute) C95.1 [1992]
 NCRP (National Council on Radia-
tion Protection and Measurement)
Report 86 [1986]
 ICNIRP (International Commission
on Non-Ionizing Radiation Protec-
tion) [1996]
Those standards were based on com-
prehensive and periodic evaluations of
the relevant scientific literature. Over
120 scientists, engi neers, and physi-
cians from universi ties, and govern-
ment health agencies and industries
reviewed the available body of
research to develop the ANSI Stan-
dard (C95.1).
The design of Safety Connect com-
plies with the FCC guidelines in addi-
tion to those standards.

shielding, and therefore emit approxi-
mately the same amount of electromag-
netic waves as conventional gasoline
powered vehicles or home electronic
appliances.
●Your vehicle may cause sound interfer-
ence in some third party-produced radio
parts.
■Hybrid battery (traction battery)
The hybrid battery (traction battery) has a
limited service life. The lifespan of the
hybrid battery (traction battery) can
change in accordance with driving style and
driving conditions.
WARNING
■High voltage precautions
This vehicle has high voltage DC and AC
systems as well as a 12-volt system. DC
and AC high voltage is very dangerous
and can cause severe burns and electric
shock that may result in death or serious
injury.
●Never touch, disassemble, remove or
replace the high voltage parts, cables
or their connectors.
●The hybrid system will become hot
after starting as the system uses high
voltage. Be careful of both the high
voltage and the high temperature, and
always obey the warning labels
attached to the vehicle.
●Never try to open the service plug
access hole located under the rear
seat (right side). The service plug is
used only when the vehicle is serviced
and is subject to high voltage.
■Road accident cautions
Observe the following precautions to
reduce the risk of death or serious injury:
●Stop the vehicle in a safe place to pre-
vent subsequent accidents. While
depressing the brake pedal, apply the
parking brake and sh ift the shift lever
to P to stop the hybrid system. Then,
slowly release the brake pedal.
●Do not touch the high voltage parts,
cables and connectors.
●If electric wires are exposed inside or
outside your vehicle, an electric shock
may occur. Never touch exposed elec-
tric wires.
●If a fluid leak occurs, do not touch the
fluid as it may be st rong alkaline elec-
trolyte from the hybrid battery (trac-
tion battery). If it comes into contact
with your skin or eyes, wash it off
immediately with a large amount of
water or, if possible, boric acid solu-
tion. Seek immediate medical atten-
tion.
●If electrolyte is leaking from the hybrid
battery (traction battery), do not
approach the vehicle.
Even in the unlikely event that the
hybrid battery (traction battery) is
damaged, the internal construction of
the battery will prev ent a large amount
of electrolyte from leaking out. How-
ever, any electrolyte that does leak out
will give off a vapor. This vapor is an
irritant to skin and eyes and could
cause acute poisoning if inhaled.
●Do not bring burning or high-tem-
perature items close to the electrolyte.
The electrolyte may ignite and cause a
fire.
●If a fire occurs in the hybrid vehicle,
leave the vehicle as soon as possible.
Never use a fire extinguisher that is not
meant for electric fires. Using even a
small amount of water may be danger-
ous.
