■There is a malfunction in the system
*1: The system judges a person of adult size as an adult. When a smaller
adult sits in the front passenger seat, the system may not recognize
him/her as an adult depending on his/her physique and posture.
*2: In the event the front passenger is wearing a seat belt.
*3: In the event the front passenge r does not wear a seat belt.
*4: For some children, child in seat, child in booster seat or chi ld in convert-
ible seat, the system may not recognize him/her as a child. Fac tors
which may affect this can be the physique or posture.
*5: Never install a rear-facing ch ild restraint system on the front passenger
seat. A forward-facing child restraint system should only be in stalled on
the front passenger sea t when it is unavoidable. ( P.50)

481-1. For safe use
Exhaust gas precau-
tions
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 closed.
●If you smell exhaust gases in
the vehicle even when the back
door is closed, open the win-
dows and have the vehicle
inspected at your Toyota dealer
as soon as possible.
■When parking
●If the vehicle is in a poorly venti-
lated 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 sys-
tem 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 corro-
sion, damage to a joint or abnor-
mal exhaust noise, be sure to
have the vehicle inspected and
repaired by your Toyota dealer.

541-2. Child safety
Move the seat to the rearmost
position
 Raise the seatback as much
as possible
 If the head restraint interferes
with the installation of the
child restraint system, and the
head restraint can be
removed, remove the head
restraint
WARNING
■When using a child restraint
system
Observe the following precau-
tions.
Failure to do so m ay result in
death or serious injury.
●Never install a rear-facing child
restraint system on the front
passenger seat even if the
“PASS AIR BAG OFF” indicator
light is illuminated. In the event
of an accident, the force of the
rapid inflation of the front pas-
senger airbag can cause death
or serious injury to the child if
the rear-facing child restraint
system is installed on the front
passenger seat.
●A forward-facing child restraint
system may be installed on the
front passenger seat only when
it is unavoidable. A child
restraint system that requires a
top tether strap should not be
used in the front passenger seat
since there is no top tether strap
anchor for the front passenger
seat.
●A forward-facing child restraint
system may be installed on the
front passenger seat only when
it is unavoidable. When install-
ing a forward-facing child
restraint system on the front
passenger seat, raise the seat-
back as much as possible, and
move the seat to the rearmost
position, even i f the “PASS AIR
BAG OFF” indicator light is illu-
minated.
If the head restraint interferes with
the installation of the child
restraint system, and the head
restraint can be removed, remove
the head restraint.
If the head restraint cannot be
removed, raise it to the uppermost
position.

■Running out of fuel
When the vehicle has run out of fuel
and the hybrid system cannot be
started, refuel th e vehicle with at least enough gasoline to make the
low fuel level warning light (
P.448)
go off. If there is only a small
amount of fuel, the hybrid system
may not be able to start. (The stan-
dard amount of fuel is about 2.9 gal.
Hybrid system precautions
Take care when handling the hybrid system, as it is a high
voltage 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.
System components

761-4. Hybrid system
limited and the distance that the
vehicle can be driven using the
electric motor (traction motor) is
reduced, the fuel economy may
be reduced.
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 mini-mize the risk of electrocution
and fuel leakage. If the emer-
gency shut off system activates,
your vehicle will not restart. To
restart the hybrid system, con-
tact your Toyota dealer.
A message is automatically dis-
played 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.456)
■If a warning light comes on, a
warning message is displayed,
or the 12-volt battery is discon-
nected
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.
NOTICE
■Hybrid battery (traction bat-
tery) air intake vent
●Make sure not to block the air
intake vent with anything, such
as a seat cover, plastic cover, or
luggage.
The input/output of the hybrid
battery (traction battery) may be
restricted, leading to a reduction
in hybrid battery (traction bat-
tery) output and a malfunction.
●Periodically clean the air intake
vents to prevent them from clog-
ging. ( P.420)
●Do not allow liquid or foreign
material to enter the air intake
vent as this may cause a short
circuit and damage the hybrid
battery (traction battery).
