After installing the child restraint system, rock it back and forth to
ensure that it is in stalled securely. ( P. 70)
■Laws and regulations pertaining to anchors
The LATCH system conforms to FMVSS225 or CMVSS210.2.
Child restraint systems conforming to FMVSS213 or CMVSS213 spec ifica-
tions can be used.
This vehicle is designed to conform to SAE J1819.
WARNING
■ When installing a child restraint system
Observe the following precautions.
Failure to do so may result in death or serious injury.
● After securing a child restraint system, never adjust the seat.
● When using the LATCH anchors, be sure that there are no foreign objects
around the anchors and that the seat belt is not caught behind the child
restraint system.
● Follow all installation instructions provided by the child rest raint 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 ef fectiveness. 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 different
position. Failure to do so may result in death or serious injur y.

on
manual enclosed with the child restraint system.
Remove the luggage cover (if equipped). ( P. 3 9 7 )
Remove the head restraint. ( P. 155)
Open the anchor bracket
cover, latch the hook onto the
anchor bracket and tighten
the top tether strap.

WARNING
■When installing a child restraint system
Observe the following precautions.
Failure to do so may result in death or serious injury.
● Firmly attach the top tether strap and make sure that the belt is not twisted.
● Do not attach the top tether strap to anything other than the anchor
bracket.
● After securing a child restraint system, never adjust the seat.
● Follow all installation instructions provided by the child rest raint system
manufacturer.
● When a child restraint system with a top tether strap is installed, do not
install the head restraint. The head restraint may interfere wi th the top
tether strap preventing secure installation of the child restraint system.
● Make sure to properly store the removed head restraint in a secure place
when you use the child restraint system on the rear seat.
NOTICE
■Anchor brackets (for top tether strap)
When not in use, make certain to close the lid. If it remains open, the lid
may be damaged.

◆When stopped/during start off
The gasoline engine stops
* when the vehicle is stopped. During
start-off, the electric motor (traction motor) drives the vehic le. At
slow speeds or when traveling down a gentle slope, the engine i s
stopped
* and the motor is used.
When the shift lever is in N, the hybrid battery (traction batt ery) is
not being charged.
*: When the hybrid battery (traction battery) requires charging o r the engine
is warming up, etc., the gasoline engine will not automatically stop.
( P. 78)
◆During normal driving
The gasoline engine is predominantly used. The electric motor
(traction motor) charges the hybr id battery (traction battery) as nec-
essary.
◆When accelerating sharply
The power of the hybrid battery (traction battery) is added to that of
the gasoline engine via the ele ctric motor (traction motor).
◆When braking (regenerative braking)
The wheels operate the electric motor (traction motor) as a pow er
generator, and the hybrid battery (traction battery) is charged.
When the gasoline engine is off while driving, a sound is produ ced to
warn pedestrians, people riding bicycles or other people and ve hicles
in the surrounding area that the vehicle is approaching. The pi tch of
the sound adjusts according to v ehicle speed. When vehicle spee d is
approximately 22 mph (35 km/h) or more, the warning system turn s
off.

Charging the hybrid batt ery (traction battery)
As the gasoline engine charges the hybrid battery (traction bat tery), the bat-
tery does not need to be charged from an outside source. Howeve r, i f t h e
vehicle is left parked for a long time the hybrid battery (trac tion battery) will
slowly discharge. For this reason, be sure to drive the vehicle at least once
every few months for at least 30 minutes or 10 miles (16 km). I f the hybrid
battery (traction battery) becomes fully discharged and you are unable to start
the hybrid system, contact your Toyota dealer.
■ Charging the 12-volt battery
P. 525
■ After the 12-volt battery has discharged or when the terminal h as been
removed and installed during exchange, etc.
The gasoline engine may not stop even if the vehicle is being driven by the
hybrid battery (traction battery). If this continues for a few days, contact your
Toyota dealer.

Hybrid system precautions
Take care when handling the hybrid system, as it is a high volt -
age system (about 520 V at maximum) as well as contains parts
that become extremely hot when the hybrid system is operating.
Obey the warning labels attached to the vehicle.

■If a warning light comes on, a warning message is displayed, or the 12-
volt battery has been disconnected
The hybrid system may not start. In this case, try to start the system again. If
the “READY” indicator does not come on, contact your Toyota dea ler.
■ Running out of fuel
When the vehicle has run out of fuel and the hybrid system cann ot be started,
refuel the vehicle with at least enough gasoline to make the lo w fuel level
warning light ( P. 482) go off. If there is only a small amount of fuel, the
hybrid system may not be able to start. (The standard amount of fuel is about
1.3 gal. [5.0 L, 1.1 Imp. gal.] when the vehicle is on a level surface. This value
may vary when the vehicle is on a slope. Add extra fuel when th e vehicle is
inclined.)
■ Electromagnetic waves
●High voltage parts and cables on hybrid vehicles incorporate el ectromag-
netic shielding, and therefore emit approximately the same amount of elec-
tromagnetic waves as conventional gasoline powered vehicles or home
electronic appliances.
● Your vehicle may cause sound interference in some third party-p roduced
radio parts.
■ Hybrid battery ( traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of
the hybrid battery (traction battery) can change in accordance with driving
style and driving conditions.

WARNING
■Road accident cautions
Observe the following precautions to reduce the risk of death o r serious
injury:
● Pull your vehicle off the road, apply the parking brake, shift the shift lever
to P, and turn the hybrid system off.
● Do not touch the high voltage parts, cables or connectors.
● If electric wires are exposed inside or outside your vehicle, an electric
shock may occur. Never touch exposed electric wires.
● If a fluid leak occurs, do not touch the fluid as it may be str ong alkaline
electrolyte from the hybrid battery (traction battery). If it c omes into contact
with your skin or eyes, wash it off immediately with a large am ount of water
or, if possible, boric acid solution. Seek immediate medical attention.
● 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 the 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. Th is may
cause a fire. ( P. 472)
● 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.
