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 may 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 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. Failure to do so 

may result in death or serious 

injury.

●

When installing a child restraint 

system in the center 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.

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. (

■

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 

sudden braking, sudden swerv-

ing or an accident.

●

Third seats: Never attach two 

child restraint systems to the 

center seat and left-hand side 

outboard seat at the same time. 

Child restraint systems may 

interfere with each other and 

may not be possible to properly 

install the child restraint sys-

tems in positions.

●

8-passenger models: Never 

attach child restraint system to 

the second center seat strikers, 

which are exposed when sec-

ond center seat is removed.

When attaching child restraint 

system to the second center 

seat, ensure the second center 

seat is securely installed and 

attach child restraint system to 

the LATCH anchors of the seat.

●

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. Failure to do so 

may result in death or serious 

injury.

Automatic Collision Notifi-
cation

In case of either airbag deploy-
ment or severe rear-end colli-
sion, the system is designed to 
automatically call the response 
center. The responding agent 
receives the vehicle’s location 
and attempts to speak with the 
vehicle occupants to assess the 
level of emergency. If the occu-
pants are unable to communi-
cate, the agent automatically 
treats the call as an emergency, 
contacts the nearest emer-
gency services provider to 
describe the situation, and 
requests that assistance be sent 
to the location.

■

Stolen Vehicle Location

If your vehicle is stolen, Safety 
Connect can work with local 
authorities to assist them in 
locating and recovering the 
vehicle. After filing a police 
report, call the Customer Experi-
ence Center at 1-800-331-4331 
in the United States, 1-877-855-
8377 in Puerto Rico or 1-888-
869-6828 in Canada, and follow 
the prompts for Safety Connect 
to initiate this service.
In addition to assisting law 
enforcement with recovery of a 
stolen vehicle, Safety-Connect-
equipped vehicle location data 
may, under certain circum-
stances, be shared with third 
parties to locate your vehicle. 
Further information is available

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-

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.

when the vehicle is stopped. 
During start off, the electric 
motor (traction motor) drives the 

vehicle. At slow speeds or when 
traveling down a gentle slope, 
the engine is stopped

electric motor (traction motor) is 
used.

Hybrid system features

Your vehicle is a Hybrid Electric 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.
