response center, which operates 24 hours per day, 7 days per
week.
Safety Connect service is available by subscription on select,
telematics hardware-equipped vehicles.

■Safety Connect Services Information
●Phone calls using the vehicle’s Bluetooth® technology will not be possible
when Safety Connect is active and in use.
● Safety Connect is available beginning Fall 2009 on select Toyot a models (in
the contiguous United States only). Contact with the Safety Con nect
response center is dependent upon the telematics device being i n operative
condition, cellular connection availability, and GPS satellite signal reception,
which can limit the ability to reach the response center or rec eive emer-
gency service support. Enrollment and Telematics Subscription S ervice
Agreement required. A variety of subscription terms is availabl e; 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 a nd Alaska,
Puerto Rico and Canada, and Enhanced Roadside Assistance are av ailable
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 I slands.
For vehicles first sold in the U.S. Virgin Islands, no Safety C onnect services
will function in or outside the U.S. Virgin Islands.
● Safety Connect services are not subject to section 255 of the T elecommuni-
cations Act and the device is not TTY compatible.
■ Languages
The Safety Connect response center will offer support in multip le 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 l ight
comes on for 2 seconds then turns off. Afterward, the green ind icator
light comes on, indicating t hat the service is active.
The following indicator light patterns indicate specific system usage
conditions:
● Green indicator light on = Active service

1012-1. Plug-in hybrid system

Plug-in hybrid system
■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. 673) 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.
■ Effect of magnetic forces
If objects that generate strong magnetic forces, such as large speakers, are
placed inside the luggage compartment or installed nearby, the generated
magnetic forces may negatively affect the hybrid system.
■ 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. 144, “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.

7-2. Maintenance

Maintenance and care
Emission inspection and maintenance (I/M)
programs
The OBD system determines that a problem exists somewhere in th e
emission control system. Your vehicle may not pass the I/M test and
may need to be repaired. Contact your Toyota dealer to service the
vehicle.
● When the 12-volt battery is disconnected or discharged
Readiness codes that are set duri ng ordinary driving are erased.
Also, depending on your driving habits, the readiness codes may
not be completely set.
● When the fuel tan k cap is loose
The malfunction indicator lamp comes on indicating a temporary
malfunction and your vehicle m ay not pass the I/M test.
The error code in th e OBD system will not be cleared unless the vehi-
cle is driven 40 or more times.
Contact your Toyota dea ler to prepare the vehicle for re-testin g.
Some states have vehicle emission inspection programs which
include OBD (On Board Diagnostics) checks. The OBD system
monitors the operation of t he emission control system.
If the malfunction indicator lamp comes on
Your vehicle may not pass the I/M test in the following situations:
When the malfunction indicator lamp still remains on after sev-
eral driving trips
If your vehicle does not pass the I/M test

9-1. Specifications
■Recommendation of the use of low emissions gasoline
Gasolines containing oxygenates such as ethers and ethanol, as well as
reformulated gasolines, are available in some cities. These fue ls are typically
acceptable for use, providing they meet other fuel requirements .
Toyota recommends these fuels, since the formulations allow for reduced
vehicle emissions.
■ Non-recommendation of the use of blended gasoline
●If you use gasohol in your vehicle, be sure that it has an octa ne rating no
lower than 87.
● Toyota does not recommend the use of gasoline containing methan ol.
■ Non-recommendation of the use of gasoline containing MMT
Some gasoline contains an octane enhancing additive called MMT
(Methylcyclopentadienyl Manganese Tricarbonyl).
Toyota does not recommend the use of gasoline that contains MMT. If fuel
containing MMT is used, your emission control system may be adversely
affected.
The malfunction indicator lamp on the instrument cluster may come on. If this
happens, contact your Toyota dealer for service.
■ If your engine knocks
●Consult your Toyota dealer.
● You may occasionally notice light knocking for a short time whi le accelerat-
ing or driving uphill. This is normal and there is no need for concern.
●
Use only gasoline containing up to 15%
ethanol.
DO NOT use any flex-fuel or gasoline
that could contain more than 15% etha-
nol, including from any pump labeled
E30, E50, E85 (which are only some
examples of fuel containing more than
15% ethanol).
DO NOT use gasoline
containing more than
15% ethanol.
(30% ethanol)
(50% ethanol)
(85% ethanol)
