For safety and security
1 To fasten the seat belt, push the plate into the buckle until
a click sound is heard.
2 To release the seat belt,
press the release button .
If the seat belt cannot be pulled out
of the retractor, firmly pull the belt
and release it.
■Emergency locking retractor
(ELR)
The retractor will lock the belt during
a sudden stop or on impact. It may
also lock if you lean forward too
quickly. A slow, easy motion will
allow the belt to extend so that you
can move around fully.
■Automatic locking retractor
(ALR)
When a passenger’s shoulder belt is
completely extended and then
retracted even slightly, the belt is
locked in that position and cannot
be extended. This feature is used to
hold the child restraint system
(CRS) firmly. To free the belt again,
fully retract the belt and then pull the
belt out once more. ( P. 5 3 )
■After using the seat belts on the
outboard rear seats
Stow the seat belt buckle in the
pockets.
WARNING
●Do not wear the seat belt
extender if you can fasten the
seat belt without the extender.
●Do not use the seat belt
extender when installing a child
restraint system because the
belt will not securely hold the
child restraint system, increas-
ing the risk of death or serious
injury in the event of an acci-
dent.
●The personalized extender may
not be safe on another vehicle,
when used by another person,
or at a different seating position
other than the one originally
intended.
NOTICE
■When using a seat belt
extender
When releasing the seat belt,
press on the buckle release but-
ton on the extender, not on the
seat belt.
This helps prevent damage to the
vehicle interior and the extender
itself.

For safety and security
WARNING
●Improperly seated and/or
restrained infants and children
can be killed or seriously injured
by a deploying airbag. An infant
or child who is too small to use
a seat belt should be properly
secured using a child restraint
system. Toyota strongly recom-
mends that all infants and chil-
dren be placed in the rear seats
of the vehicle and properly
restrained. The rear seats are
safer for infants and children
than the front pa ssenger seat.
(  P.53)
●Do not sit on the edge of the
seat or lean against the dash-
board.
●Do not allow a child to stand in
front of the SRS front passenger
airbag unit or sit on the knees of
a front passenger.
●Do not allow the front seat occu-
pants to hold items on their
knees.
●Do not lean against the door,
the roof side rail or the front,
side and rear pillars.
●Do not allow anyone to kneel on
the passenger seats toward the
door or put their head or hands
outside the vehicle.
●Do not attach anything to or
lean anything against areas
such as the dashboard, steering
wheel pad and lower portion of
the instrument panel.
These items can become pro-
jectiles when th e SRS driver,
front passenger and knee air-
bags deploy.

661-2. Child safety
Owners Manual_USA_M0C052_enlow as possible. (
P.29)
■Removing a child restraint
system installed with a seat
belt
Press the buckle release button
and fully retract the seat belt.
When releasing the buckle, the
child restraint system may spring
up due to the rebound of the seat
cushion. Release the buckle while
holding down the child restraint
system.
Since the seat belt automatically
reels itself, slowly return it to the
stowing position.
WARNING
■When installing a child
restraint system
Observe the following precau-
tions.
Failure to do so m ay result in
death or serious injury.
●Do not allow children to play
with the seat belt. If the seat belt
becomes twisted around a
child’s neck, it may lead to
choking or other serious injuries
that could result in death.
If this occurs and the buckle
cannot be unfastened, scissors
should be used to cut the belt.
●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.
●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.
●Follow all installation instruc-
tions 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 effective-
ness. 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 differ-
ent position. Fa ilure to do so
may result in death or serious
injury.

711-3. Emergency assistance
Owners Manual_USA_M0C052_en

For safety and security
necessary assistance required.
If you accidentally press the “SOS”
button, tell the response-center
agent that you are not experiencing
an emergency.
■Enhanced Roadside Assis-
tance
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 Roadside
Assistance services and their
limitations, please see the
Safety Connect Terms and Con-
ditions, which are available at
Toyota.com.
Important! Read this informa-
tion about exposure to radio fre-
quency signals before using
Safety Connect;
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 wireless phones. Those
guidelines are consistent with
the safety standards 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
Measurement) Report 86
[1986]
 ICNIRP (International Com-
mission on Non-Ionizing Radi-
ation Protection) [1996]
Those standards were based on
comprehensive and periodic
evaluations of the relevant sci-
entific literature. Over 120 scien-
tists, engineers, and physicians
from universities, and govern-
ment health agencies and
industries reviewed the avail-
able body of research to
develop the ANSI Standard
(C95.1).
The design of Safety Connect
complies with the FCC guide-
lines in addition to those stan-
dards.
