WARNING
■When installing a child restraint system
● When installing a child restraint system on the center second and third
seat, adjust both seat cushions to the same position (second seat only)\
and align both seatbacks at the same angle. The seatbacks must be
adjusted to the same angle. Otherwise, the child restraint system cannot
be securely restrained and this may cause death or serious injury in the
event of sudden braking, sudden swerving or an accident.
● When using the LATCH anchors for a child restraint system, move the seat
as far back as possible (second seat only), with the seatback close to the
child restraint system.
● 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. Failing to do so may result in death or serious injury in the event
of sudden braking, sudden swerving or an accident.
● 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.
● Follow all installation instructions provided by the child restraint system
manufacturer.
● When securing some types of child restraint systems in second or third
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
effectiveness. 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
injury.

WARNING
■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 sud-
den braking, sudden swerving or an accident.
■ To correctly attach a child r estraint system to the anchors
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. Make sure the child restraint system is securely attached,
or it may cause death or serious injury to the child or other passengers in
the event of sudden braking, sudden swerving or an accident.

Exhaust gas precautions
Harmful substance to the human body is included in exhaust
gases if inhaled.
WARNING
Exhaust gases include harmful carbon monoxide (CO), which is colorless and
odorless. Observe the following precautions.
Failure to do so may cause exhaust gases enter the vehicle and may lead to
an accident caused by light-headedness, or may lead to death or a serious
health hazard.
■Important points while driving
● Keep the back door and glass hatch closed.
● If you smell exhaust gases in the vehicle even when the back door and
glass hatch are closed, open the windows and have the vehicle inspected
at your Toyota dealer as soon as possible.
■ When parking
● If the vehicle is in a poorly ventilated area or a closed area, such as a
garage, stop the hybrid system.
● Do not leave the vehicle with the hybrid system on for a long time.
If such a situation cannot be avoided, park the vehicle in an open space
and ensure that exhaust fumes do not enter the vehicle interior.
● Do not leave the hybrid system operating in an area with snow build-up, or
where it is snowing. If snowbanks build up around the vehicle while the
hybrid system is operating, exhaust gases may collect and enter the vehi\
-
cle.
■ Exhaust pipe
The exhaust system needs to be checked periodically. If there is a hole or
crack caused by corrosion, damage to a joint or abnormal exhaust noise, be
sure to have the vehicle inspected and repaired by your Toyota dealer.

◆When stopped/during start off
The gasoline engine stops
* 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
* and the electric motor (traction motor) is used.
When the shift lever is in N, the hybrid battery (traction battery) is
not being charged.
*: When the hybrid battery (traction battery) requires charging or the engine is warming up, etc., the gasoline engine will not automatically
stop. ( →P. 83)
◆During normal driving
The gasoline engine is predomin antly used. The electric motor
(traction motor) charges the hybrid battery (traction battery) as nec-
essary.
◆When accelerating sharply
When the accelerator pedal is depressed heavily, the power of the
hybrid battery (traction battery) is added to that of the gasoline
engine via the electric motor (traction motor).
◆When braking (regenerative braking)
The wheels operate the electric motor (traction motor) as a power
generator, and the hybrid battery (traction battery) is charged.
When the gasoline engine is off while driving, a sound is produced to
warn pedestrians, people riding bi cycles or other people and vehicles
in the surrounding area that the vehi cle is approaching. The pitch of
the sound adjusts according to vehi cle speed. When vehicle speed is
approximately 16 mph (25 km/h) or more, the warning system turns
off.

Hybrid system precautions
Take care when handling the hybrid system, as it is a high volt-
age system (about 650 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.

There are air intake vents under
the second seats for the purpose
of cooling the hybrid battery (trac-
tion battery). If the vents become
blocked, the hybrid battery may
overheat, leading to a reduction in
hybrid battery output.
When a certain level of impact is detected by the impact sensor, the
emergency shut off system blocks the high voltage current and stops
the fuel pump to minimize the risk of electrocution and fuel leakage. If
the emergency shut off sy stem activates, your vehicle will not restart.
To restart the hybrid system, contact your Toyota dealer.
A message is automatically displa yed when a malfunction occurs in
the hybrid system or an improper operation is attempted.
If a warning message is shown on
the multi-information display, read
the message and follow the
instructions. ( →P. 577)

■If a warning light comes on, a warn ing message is displayed, or the 12-
volt battery is 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 dealer.
■ When refueling, the fuel filler door may take a few moments to open
As part of emission system operation, it may take up to 10 seconds for the
fuel filler door to automatically release after the opener switch is pressed.
Before refueling is possible, a message will be shown on the multi-informa-
tion display. ( →P. 256)
■ Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started,
refuel the vehicle with at least enough gasoline to make the low fuel le\
vel
warning light ( →P. 568) 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
2.6 gal. [9.7 L, 2.1 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 the vehi-
cle is inclined.)
■ Electromagnetic waves
●High voltage parts and cables on hybrid vehicles incorporate electromag-
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-produced
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
■High voltage precautions
This vehicle has high voltage DC and AC systems as well as a 12-volt sys-
tem. DC and AC high voltage is very dangerous and can cause severe
burns and electric shock that may result in death or serious injury.
● Never touch, disassemble, remove or replace the high voltage parts,
cables or their connectors.
● The hybrid system will become hot after starting as the system uses high
voltage. Be careful of both the high voltage and the high temperature, and
always obey the warning labels attached to the vehicle.
●Never try to open the service plug
access hole located on the left-hand
side of the second seat base. The ser-
vice plug is used only when the vehicle
is serviced and is subject to high volt-
age.
