Please note that this manual applies to all models and explains all equipment,
including options. Therefore, you may find some explanations for equipment
not installed on your vehicle.
All specifications provided in this manual are current at the time of printing.
However, because of the Toyota policy of continual product improvement, we
reserve the right to make changes at any time without notice.
Depending on specifications, the vehicle shown in the illustrations may differ
from your vehicle in terms of equipment.
Approximately five hours after the hybrid system is turned off, you may hear
sound coming from under the vehicle for several minutes. This is the sound of
a fuel evaporation leakage check and, it does not indicate a malfunction.
A wide variety of non-genuine spare parts and accessories for Toyota vehi-
cles are currently available in the market. You should know that Toyota does
not warrant these products and is not responsible for their performance,
repair, or replacement, or for any damage they may cause to, or adverse
effect they may have on, your Toyota vehicle.
This vehicle should not be modified with non-genuine Toyota products. Modi-
fication with non-genuine Toyota products could affect its performance, safety
or durability, and may even violate governmental regulations. In addition,
damage or performance problems resulting from the modification may not be
covered under warranty.

The installation of a mobile two-way radio system in your vehicle could affect
electronic systems such as:
●Multiport fuel injection system/sequential multiport fuel injection system
●Toyota Safety Sense P
●Anti-lock brake system
●SRS airbag system
●Seat belt pretensioner system
Be sure to check with your Toyota dealer for precautionary measures or spe-
cial instructions regarding installation of a mobile two-way radio system.
High voltage parts and cables on the hybrid vehicles emit approximately the
same amount of electromagnetic waves as the conventional gasoline pow-
ered vehicles or home electronic appliances despite of their electromagnetic
shielding.
Unwanted noise may occur in the reception of the mobile two-way radio.

721-2. Emergency assistance
■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 automati-
cally treats the call as an emergency, contacts the nearest emer-
gency 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 author-
ities to assist them in locating and recovering the vehicle. After filing
a police report, call the Customer Experience Center at 1-800-331-
4331 in the United States, 1-877-855-8377 in Puerto Rico or 1-888-
869-6828 in Canada, and follow the prompts for Safety Connect to
initiate this service.
In addition to assisting law enforcement with recovery of a stolen
vehicle, Safety-Connect-equipped vehicle location data may, under
certain circumstances, be shared with third parties to locate your
vehicle. Further information is available at Toyota.com in the United
States, Toyotapr.com in Puerto Rico and Toyota.ca in Canada.
■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 necessary assistance required.
If you accidentally press the “SOS” button, tell the response-center
agent that you are not experiencing an emergency.
■
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 Connect
response-center agent, who can help with a wide range of needs,
such as: towing, flat tire, fuel delivery, etc. For a description of the
Enhanced Roadside Assistance services and 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 and Toyota.ca in Canada.

Your vehicle is a hybrid vehicle. It has characteristics different
from conventional vehicles. Be sure you are closely familiar with
the characteristics of your vehicle, and operate it with care.
The hybrid system combines the use of a gasoline engine and
an electric motor (traction motor) according to driving condi-
tions, improving fuel efficiency and reducing exhaust emis-
sions.
