◆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
■Road accident cautions
Observe the following precautions to reduce the risk of death or serious
injury:
● Pull your vehicle off the road, apply the parking brake, shift the shift posi-
tion to P, and turn the hybrid system off.
● 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 battery) is dam-
aged, the internal construction of the battery will prevent a large amount of
electrolyte from leaking out. However, 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-temperat ure items close to the electrolyte.
The electrolyte may ignite and cause a fire.
● 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 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. 646)
● 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.

Cargo and luggage
Cargo capacity depends on the total weight of the occupants.
(Cargo capacity) = (Total load capacity) — (Total weight of occupants)
Steps for Determining Correct Load Limit ⎯
(1) Locate the statement “The comb ined weight of occupants and
cargo should never exceed XXX kg or XXX lbs.” on your vehicle’s
placard.
(2) Determine the combined weight of the driver and passengers that
will be riding in your vehicle.
(3) Subtract the combined weight of the driver and passengers from
XXX kg or XXX lbs.
(4) The resulting figure equals the available amount of cargo and lug- gage load capacity.
For example, if the “ XXX” amount equals 1400 lbs. and there will be
five 150 lb passengers in your v ehicle, the amount of available
cargo and luggage load capacity is 650 lbs. (1400 − 750 (5 × 150) =
650 lbs.)
(5) Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight ma y not safely exceed the available
cargo and luggage load capacity calculated in Step 4.
(6) If your vehicle will be towing a tr ailer, load from your trailer will be
transferred to your vehicle. Consult this manual to determine how
this reduces the available cargo and luggage load capacity of your
vehicle. ( →P. 321)
Toyota does not recommend towing a trailer with your vehicle. Your
vehicle is not designed for trailer towing.
Take notice of the following information about storage precau-
tions, cargo capacity and load.

Vehicle load limits
◆Total load capacity (vehicle capacity weight): →P. 708
Total load capacity means the comb ined weight of occupants, cargo
and luggage.
◆Seating capacity: 4 occupants (Front 2, Rear 2)
Seating capacity means the maxi mum number of occupants whose
estimated average weight is 150 lb. (68 kg) per person.
◆Towing capacity
Toyota does not recommend towing a trailer with your vehicle.
◆Cargo capacity
Cargo capacity may increase or decrease depending on the weight
and the number of occupants.
■Total load capacity and seating capacity
These details are also described on the tire and loading information label.
( → P. 603)
Vehicle load limits include total load capacity, seating capacity,
towing capacity and cargo capacity.
WARNING
■Overloading the vehicle
Do not overload the vehicle.
It may not only cause damage to the tires, but also degrade steering
and braking ability, resu lting in an accident.

Trailer towing
Toyota does not recommend towing a trailer with your vehicle.
Toyota also does not recommend the installation of a tow hitch
or the use of a tow hitch carrier for a wheelchair, scooter, bicy-
cle, etc. Your vehicle is not desi gned for trailer towing or for the
use of tow hitch mounted carriers.
