661-1. For safe use
WARNING
■When installing a booster seat
To prevent the belt from going into ALR lock mode, do not fully extend the
shoulder belt. ALR mode causes the belt to tighten only. This could cause
injury or discomfort to the child. (P. 30)
■When installing a child restraint system
Follow the directions given in the child restraint system installation manual
and fix the child restraint system securely in place.
If the child restraint system is not correctly fixed in place, the child or other
passengers may be seriously injured or even killed in the event of sudden
braking, sudden swerving or an accident.
●If the driver’s seat interferes with the
child restraint system and prevents it
from being attached correctly, attach the
child restraint system to the right-hand
rear seat.
●Adjust the front passenger seat so that
it does not interfere with the child
restraint system.
●Only put a forward-facing child restraint
system on the front seat when unavoid-
able. When installing a forward-facing
child restraint system on the front pas-
senger seat, move the seat as far back
as possible even if the “AIR BAG OFF”
indicator light is illuminated. Failure to
do so may result in death or serious
injury if the airbags deploy (inflate).

WARNING
■When installing a child restraint system
●When a booster seat is installed, always ensure that the shoulder belt is
positioned across the center of the child’s shoulder. The belt should be
kept away from the child’s neck, but not so that it could fall off the child’s
shoulder. Failing to do so may result in death or serious injury in the event
of sudden braking, sudden swerving or an accident.
●Ensure that the belt and plate are securely locked and the seat belt is not
twisted.
●Shake the child restraint system left and right, and forward and backward
to ensure that it has been securely installed.
●After securing a child restraint system, never adjust the seat.
●Follow all installation instructions provided by the child restraint system
manufacturer.
●When securing some types of child restraint systems in rear seats, it may
not be possible to properly use the seat belts in positions next to the child
restraint without interfering with it or affecting seat belt effectiveness. Be
sure your seat belt fits snugly across your shoulder and low on your hips. If
it does not, or if it interferes with the child restraint, move to a different
position. Failure to do so may result in death or serious injury.
■Do not use a seat belt extender
If a seat belt extender is used when installing a child restraint system, the
seat belt will not securely hold the child restraint system, which could cause
death or serious injury to the child or other passengers in the event of a sud-
den braking, sudden swerving or an accident.
■To correctly attach a child restraint system to the anchors
When using the LATCH anchors, be sure that there are no foreign objects
around the anchors and that the seat belt is not caught behind the child
restraint. Make sure the child restraint system is securely attached, or it
may cause death or serious injury to the child or other passengers in the

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 are required. A variety of subscription terms are available;
charges vary by subscription term selected and location.

Important! Read this information before using Safety Connect.
■Exposure to radio frequency signals
The Safety Connect system installed in your vehicle is a low-power
radio transmitter and receiver. It 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 wire-
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 Standards Institute) C95.1 [1992]
●NCRP (National Council on Radiation 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 scientific literature. Over 120 scientists, engi-
neers, and physicians from universities, 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 in
addition to those standards.

Hybrid system features
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.

■Regenerative braking
In the following situations, kinetic energy is converted to electric energy and
deceleration force can be obtained in conjunction with the recharging of the
hybrid battery (traction battery).
●The accelerator pedal is released while driving with the shift lever in D or S.
●The brake pedal is depressed while driving with the shift lever in D or S.
■EV indicator
■Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop
automatically in the following conditions:
●During gasoline engine warm-up
●During hybrid battery (traction battery) charging
●When the temperature of the hybrid battery (traction battery) is high or low
●When the heater is switched on
■Charging the hybrid battery (traction battery)
As the gasoline engine charges the hybrid battery (traction battery), the bat-
tery does not need to be charged from an outside source. However, if the
vehicle is left parked for a long time the hybrid battery (traction battery) will
slowly discharge. For this reason, be sure to drive the vehicle at least once
every few months for at least 30 minutes or 10 miles (16 km). If the hybrid
battery (traction battery) becomes fully discharged and you are unable to start
the hybrid system, contact your Toyota dealer.
■Charging the 12-volt battery
P. 490
■After the 12-volt battery has discharged or when the terminal has been
removed and installed during exchange, etc.
The gasoline engine may not stop even if the vehicle is being driven by the
hybrid battery (traction battery). If this continues for a few days, contact your
Toyota dealer. The EV indicator comes on when the
vehicle is driven using only the electric
motor (traction motor) or the gasoline
engine is stopped.
