■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.

671-2. Child safety
1
For safety and security
■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.
●After securing a child restraint
system, never adjust the seat.
●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 s eat 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.
●When installing a child restraint
system in the ce nter rear seat,
adjust both seatbacks at the
same angle. Otherwise, the
child restraint system cannot be
securely restrained and this
may cause death or serious
injuries in the event of sudden
braking, sudden swerving or an
accident.

781-3. Emergency assistance
■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 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.
Important! Read this informa-
tion before using Safety Con-
nect.
■Exposure to radio fre-
quency 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 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.

851-4. Hybrid system
1
For safety and security
There are air intake vents under
the front seats for the purpose of
cooling the hybrid battery (trac-
tion battery). If the vent
becomes blocked, the hybrid
battery (traction battery) may
overheat, leading to a reduction
in hybrid battery (traction bat-
tery) output.
WARNING
●If a fire occurs in the hybrid
vehicle, leave the vehicle as
soon as possible. Never use a
fire extinguisher that is not
meant for electric fires. Using
even a small amount of water
may be dangerous.
●If your vehicle needs to be
towed, do so with four wheels
raised. If the wheels connected
to the electric motor (traction
motor) are on the ground when
towing, the motor may continue
to generate electricity. This may
cause a fire. ( P.460)
●Carefully inspect the ground
under the vehicle. If you find
that liquid has leaked onto the
ground, the fuel system may
have been damaged. Leave the
vehicle as soon as possible.
■Hybrid battery (traction bat-
tery)
●Never resell, hand over or mod-
ify the hybrid battery. To prevent
accidents, hybrid batteries that
have been removed from a dis-
posed vehicle are collected
through Toyota dealer. Do not
dispose of the battery yourself.
Unless the battery is properly col-
lected, the follo wing may occur,
resulting in dea th or serious
injury:
• The hybrid battery may be ille- gally disposed of or dumped,
and it is hazardous to the envi-
ronment or someone may touch
a high voltage part, resulting in
an electric shock.
• The hybrid battery is intended to be used exclusively with your
hybrid vehicle. If the hybrid bat-
tery is used out side of your
vehicle or modified in any way,
accidents such as electric
shock, heat generation, smoke
generation, an explosion and
electrolyte leakage may occur.
When reselling or handing over
your vehicle, the possibility of an
accident is extremely high
because the person receiving the
vehicle may not be aware of these
dangers.
●If your vehicle is disposed of
without the hybrid battery hav-
ing been removed, there is a
danger of serious electric shock
if high voltage parts, cables and
their connectors are touched. In
the event that your vehicle must
be disposed of, the hybrid bat-
tery must be disposed of by
your Toyota dealer or a qualified
service shop. If the hybrid bat-
tery is not disposed of properly,
it may cause electric shock that
can result in dea th or serious
injury.
