when Safety Connect is active and in use.
●Safety Connect is available beginning Fall 2009 on select Toyota models (in
the contiguous United States only). Contact with the Safety Connect
response center is dependent upon the telematics device being in operative
condition, cellular connection availability, and GPS satellite signal reception,
which can limit the ability to reach the response center or receive emer-
gency service support. Enrollment and Telematics Subscription Service
Agreement required. A variety of subscription terms is available; charges
vary by subscription term selected and location.
●Automatic Collision Notification, Emergency Assistance and Stolen Vehicle
Location are available in the United States, including Hawaii and Alaska,
Puerto Rico and Canada, and Enhanced Roadside Assistance are available
in the United States, Puerto Rico and Canada.
●Automatic Collision Notification, Emergency Assistance, Stolen Vehicle and
Enhanced Road Assistance are not available in the U.S. Virgin Islands.
For vehicles first sold in the U.S. Virgin Islands, no Safety Connect services
will function in or outside the U.S. Virgin Islands.
●Safety Connect services are not subject to section 255 of the Telecommuni-
cations Act and the device is not TTY compatible.
■Languages
The Safety Connect response center will offer support in multiple languages.
The Safety Connect system will offer voice prompts in English, Spanish, and
French. Please indicate your language of choice when enrolling.
■When contacting the response center
You may be unable to contact the response center if the network is busy.
When the power switch is turned to 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
conditions:
●Green indicator light on = Active service

●By keeping the indicator within Eco area, more Eco-friendly driv-
ing can be achieved.
●Charge area indicates regeneration
*4 status. Regenerated
energy will be used to charge the hybrid battery (traction battery).

*2: Not displayed on the sub-screen.
*3: The EV indicator function can be turned off in the “Meter Customize”
settings. (P. 248)
*4: When used in this manual, “regeneration” refers to the conversion of
energy created by the movement of the vehicle into electrical energy.

“ECO Accelerator Guidance”
A blue zone is displayed in the Eco area which can be used as a
reference operation range for using the accelerator pedal according
to driving conditions such as starting off and cruising.
The “ECO Accelerator Guidance” display changes according to the driv-
ing status, such as when starting off or cruising.
It is easier to drive in an Eco-friendly manner by driving according to the
display showing the accelerator pedal operations and staying within the
“ECO Accelerator Guidance” range. (P. 322)
The “ECO Accelerator Guidance” function can be turned off in the
“Meter Customize” settings. (P. 248)

■When operation of each function stops
●The Hybrid System Indicator stops operating in the following situations.
• The “READY” indicator is not illuminated.
• The shift position is not D or B.
●The Eco score and “ECO Accelerator Guidance” stop operating in the fol-
lowing situations.
• The Hybrid System Indicator is not operating.
• Dynamic radar cruise control with full-speed range is being used.
■Display of the remaining hybrid battery (traction battery)
●The current amount of the remaining hybrid battery (traction battery) is dis-
played in the Hybrid System Indicator or the sub-screen on the main display.
(P. 217)
• The remaining battery for EV driving in EV mode is displayed in green,
and the remaining battery used in HV mode is displayed in blue.
• The amount of the remaining battery displayed decrease as the vehicle is
driven and increase when the hybrid battery (traction battery) is charged,
electrical energy is regenerated using the regenerative braking (P. 94)
or electricity is generated by the gasoline engine.
• If the remaining battery is not displayed in green, HV mode is automati-
cally selected and EV mode cannot be used. To enable EV driving,
charge the hybrid battery (traction battery). (P. 110)
●The amount of the hybrid battery (traction battery) in HV mode is automati-
cally controlled by the hybrid system. The amount of remaining hybrid battery
(traction battery) in HV mode may not reach the top line
* even if electrical
energy is regenerated using the regenerative braking (P. 94) or electricity
is generated by the gasoline engine. However, this does not indicate a mal-
function. Also, even if the display of the remaining hybrid battery (traction
battery) exceeds the top line, the display is shown in blue until the vehicle
returns to EV mode.

●Depending on the charging situation, when the display of the remaining
hybrid battery (traction battery) is shown during charging, charging contin-
ues even after the display of the remaining hybrid battery (traction battery)
shows a fully charged state. However, this does not indicate a malfunction.
