■Enhanced Roadside Assistance
Enhanced Roadside Assistance adds GPS data to the already
included warranty-based Toyota roadside service.
Subscribers can press the “SOS” button to reach a Safety Connec t
response-center agent, who can he lp with a wide range of needs,
such as: towing, flat tire, fuel delivery, etc. For a description of the
Roadside Assistance services an d their limitations, please see the
Safety Connect Terms and Conditions, which are available at
Toyota.com in the United States, Toyotapr.com in Puerto Rico an d
Toyota.ca in Canada.
Important! Read this informatio n before using Safety Connect.
■Exposure to radio frequency signals
The Safety Connect system installed in your vehicle is a low-po wer
radio transmitter and receiver. I t receives and also sends out radio
frequency (RF) signals.
In August 1996, the Federal Communications Commission (FCC)
adopted RF exposure guidelines with safety levels for mobile wi re-
less phones. Those guidelines are consistent with the safety stan-
dards previously set by the following U.S. and international
standards bodies.
● ANSI (American National Stand ards Institute) C95.1 [1992]
● NCRP (National Council on Radi ation Protection and Measure-
ment) Report 86 [1986]
● ICNIRP (International Commission on Non-Ionizing Radiation
Protection) [1996]
Those standards were based on comprehensive and periodic eval-
uations of the relevant scienti fic literature. Over 120 scientists, engi-
neers, and physicians from unive rsities, 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 i n
addition to those standards.

Plug-in hybrid system precautions
The illustration is an example for explanation and may differ from the
actual item.
Take care when handling the hybrid system, as it contains a high
voltage system (about 600V at maximum) as well as parts that
become extremely hot when th e hybrid system is operating.
Obey the caution labels attached to the vehicle.

■If a warning light comes on, a warning message is displayed or the 12-
volt battery is disconnected
The hybrid system may not start. In that case, try to start the system again. If
the “READY” indicator does not come on, contact your Toyota dea ler.
■ Running out of fuel
When the vehicle has run out of fuel and the hybrid system cann ot be started,
refuel the vehicle with at least enough gasoline to make the lo w fuel level
warning light ( P. 662) go off. If there is only a small amount of fuel, the
hybrid system may not be able to start. (The standard amount of fuel is about
2.0 gal. [7.5 L, 1.7 Imp.gal.], when the vehicle is on a level surface. This value
may vary when the vehicle is on a slope. Add extra fuel when th e vehicle is
inclined.)
■ Electromagnetic waves
●High voltage parts and cables on the hybrid vehicles incorporat e electro-
magnetic shielding, and therefore emit approximately the same amount of
electromagnetic waves as conventional gasoline powered vehicles or home
electronic appliances.
● Your vehicle may cause sound interference in some third party-p roduced
radio parts.
■ Hybrid battery (traction batt ery) (lithium-ion battery)
The hybrid battery (traction battery) has a limited service lif e.
The hybrid battery (traction battery) capacity (the ability to hold a charge)
reduces with time and use in the same way as other rechargeable batteries.
The extent at which capacity reduces changes drastically depending on the
environment (ambient temperature, etc.) and usage conditions, such as how
the vehicle is driven and how the hybrid battery (traction batt ery) is charged.
This is a natural characteristic of lithium-ion batteries, and is not a malfunc-
tion. Also, even though the distance that can be driven in EV m ode decreases
when the hybrid battery (traction battery) capacity reduces, ve hicle perfor-
mance does not significantly become worse.
In order to reduce the possibility of the capacity reducing, fo llow the directions
listed on P. 140, “Capacity reduction of the hybrid battery (tr action battery)”.
■ Starting the hybrid system in a n extremely cold environment
When the hybrid battery (traction battery) is extremely cold (b elow approxi-
mately -22 F [-30C]) under the influence of the outside temperature, it may
not be possible to start the hybrid system. In this case, try to start the hybrid
system again after the temperature of the hybrid battery increases due to the
outside temperature increase etc.

WARNING
■High voltage precautions
The vehicle has high voltage DC and AC systems as well as a 12- volt sys-
tem. DC and AC high voltage is very dangerous and can cause sev ere
burns and electric shock that may result in death or serious in jury.
● Never touch, disassemble, remove or replace the high voltage pa rts,
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 tempe rature, and
always obey the caution labels attached to the vehicle.
● Never try to open the service plug
access hole located in the luggage
compartment. The service plug is used
only when the vehicle is serviced and is
subject to high voltage.

WARNING
■Hybrid battery (traction battery)
● Your vehicle contains a sealed lithium-ion battery.
● Never resell, hand over or modify the hybrid battery. To preven t accidents,
hybrid batteries that have been removed from a disposed vehicle are col-
lected through Toyota dealer. Do not dispose of the battery yourself.
Unless the battery is properly collected, the following may occur, resulting
in death or serious injury:
• The hybrid battery may be illegally disposed of or dumped, and it is haz-
ardous to the environment or someone may touch a high voltage p art,
resulting in an electric shock.
• The hybrid battery is intended to be used exclusively with you r hybrid
vehicle. If the hybrid battery is used outside of your vehicle or modified
in any way, accidents such as electric shock, heat generation, smoke
generation, an explosion and electrolyte leakage may occur.
When reselling or handing over your vehicle, the possibility of an acci-
dent is extremely high because the person receiving the vehicle may
not be aware of these dangers.
● If your vehicle is disposed of without the hybrid battery havin g been
removed, there is a danger of serious electric shock if high vo ltage parts,
cables and their connectors are touched. In the event that your vehicle
must be disposed of, the hybrid battery must be disposed of by your Toy-
ota dealer or a qualified service shop. If the hybrid battery is not disposed
of properly, it may cause electric shock that can result in dea th or serious
injury.
