591-2. Child safety
1
For safety and security
buckle. Make sure that the
belt is not twisted.
Check that the shoulder belt is cor-
rectly positioned over the child’s
shoulder and that the lap belt is as
low as possible. (P.31)
■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.

681-3. 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.

Plug-in hybrid system
WARNING
●Never try to open the service
plug access hole located in the
luggage compartment. The ser-
vice plug is used only when the
vehicle is serviced and is sub-
ject to high voltage.
■Road accident cautions
Observe the following precautions
to reduce the risk of death or seri-
ous injury:
●Stop the vehicle in a safe place
to prevent subsequent acci-
dents. While depressing the
brake pedal, apply the parking
brake and shift the shift position
to P to stop the Plug-in hybrid
system. Then, slowly release
the brake pedal.
●Do not touch the high voltage
parts, cables and connectors.
●If electric wires are exposed
inside or outside your vehicle,
an electric shock may occur.
Never touch exposed electric
wires.
●Do not touch the battery if liquid
is leaking from or adhering to it.
If electrolyte (carbonic-based
organic electrolyte) from the
hybrid battery (traction battery)
comes into contact with the
eyes or skin, it could cause
blindness or skin wounds. In the
unlikely event that it comes into
contact with the eyes or skin,
wash it off immediately with a
large amount of water, and seek
immediate medical attention.
●If electrolyte is leaking from the
hybrid battery (traction battery),
do not approach the vehicle.
Even in the unlikely event that
the hybrid battery (traction bat-
tery) is damaged, the internal
construction of the battery will
prevent a large amount of elec-
trolyte from leaking out. How-
ever, any electrolyte that does
leak out will give off a vapor.
This vapor is an irritant to skin
and eyes and could cause acute
poisoning if inhaled.
●Do not bring burning or high-
temperature items close to the
electrolyte. The electrolyte may
ignite and cause a fire.
●If a fire occurs in the Plug-in
Hybrid Electric 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 dan-
gerous.
●If your vehicle needs to be
towed, do so with front 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.550)
●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)
●Your vehicle contains a sealed
lithium-ion battery.

2485-1. Before driving
(6) If your vehicle will be towing
a trailer, load from your trailer
will be transferred to your vehi-
cle. Consult this manual to
determine how this reduces the
available cargo and luggage
load capacity of your vehicle.
(P.249)
Toyota does not recommend
towing a trailer with your vehicle.
Your vehicle is not designed for
trailer towing.
Cargo capacity
Total load capacity (vehicle
capacity weight) ( P.600) When 2 people with the com-
bined weight of A lb. (kg) are rid-
ing in your vehicle, which has a
total load capacity (vehicle
capacity weight) of B lb. (kg),
the available amount of cargo
and luggage load capacity will
be C lb. (kg) as follows:
B
*2 lb. (kg) - A*1 lb. (kg) = C*3 lb.
(kg)
*1: A = Weight of people
*2: B = Total load capacity
*3: C = Available cargo and luggage load
In this condition, if 3 more passen-
gers with the combined weight of D
lb. (kg) get on, the available cargo
and luggage load will be reduced E
lb. (kg) as follows:
C lb. (kg) - D*4 lb. (kg) = E*5 lb.
(kg)
*4: D = Additional weight of people
*5: E = Available cargo and luggage load
As shown in the example above,
if the number of occupants
increases, the cargo and lug-
gage load will be reduced by an
amount that equals the
increased weight due to the
additional occupants. In other
words, if an increase in the num-
ber of occupants causes an
excess of the total load capacity
(combined weight of occupants
plus cargo and luggage load),
you must reduce the cargo and
luggage on your vehicle.
WARNING
■Capacity and distribution
●Do not exceed the maximum
axle weight rating or the total
vehicle weight rating.
●Even if the total load of occu-
pant’s weight and the cargo
load is less than the total load
capacity, do not apply the load
unevenly. Improper loading may
cause deterioration of steering
or braking control which may
cause death or serious injury.

■Total load capacity and seating
capacity
These details are also described on
the tire and loading information
label. ( P.532)
Vehicle load limits
Vehicle load limits include
total load capacity, seating
capacity, towing capacity
and cargo capacity.
 Total load capacity (vehicle
capacity weight): P.600
Total load capacity means the
combined weight of occu-
pants, cargo and luggage.
 Seating capacity: P.600
Seating capacity means the
maximum number of occu-
pants whose estimated aver-
age weight is 150 lb. (68 kg)
per person.
 Towing capacity
Toyota does not recommend
towing a trailer with your vehi-
cle.
 Cargo capacity
Cargo capacity may increase
or decrease depending on the
weight and the number of
occupants.
WARNING
■Overloading the vehicle
Do not overload the vehicle. It
may not only cause damage to
the tires, but also degrade steer-
ing and braking ability, resulting in
an accident.
