Exhaust gas precautions
Harmful substance to the
human body is included in
exhaust gases if inhaled.
WARNING
Exhaust gases include harmful car-
bon monoxide (CO), which is color- less 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 windows and have
the vehicle inspected at any autho- rized Toyota retailer or Toyota authorized repairer, or any reliable
repairer 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 engine.
●Do not leave the vehicle with the engine 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 engine running in an area with snow build-up, or where it is snowing. If snowbanks
build up around the vehicle while the engine is running, exhaust gases may collect and enter the

ings, as well as the laws and reg-
ulations for child restraint
systems.
 Use a child restraint system until
the child becomes large enough
to properly wear the vehicle’s
seat belt.
 Choose a child restraint system
appropriate to the age and size
of the child.
 Note that not all child restraint
systems can fit in all vehicles.
Before using or purchasing a
child restraint system, check the

( P. 4 9 )
Child restraint systems
Before installing a child
restraint system in the vehicle,
there are precautions that need
to be observed, different types
of child restra int systems, as
well as installation methods,
etc., written in this manual.
 Use a child restraint system
when riding with a small child
that cannot properly use a seat
belt. For the child’s safety,
install the child restraint sys-
tem to a rear seat. Be sure to
follow the installation method
that is in the operation manual
enclosed with the restraint sys-
tem.
 The use of a Toyota genuine
child restraint system is rec-
ommended, as it is safer to
use in this vehicle. Toyota gen-
uine child restraint systems
are made specifically for
Toyota vehicles. They can be
purchased at a Toyota dealer.

■When installing a child
restraint system to a front pas-
senger seat
For the safety of a child, install a
child restraint system to a rear seat.
When installing a child restraint
system to a front passenger seat is
unavoidable, adjust the seat as fol-
lows and install the child restraint
system:
 Move the front seat fully rear-
ward.
 Adjust the seatback angle to the
most upright position.
When installing a forward-facing child
seat, if there is a gap between the child
seat and the seatback, adjust the
seatback angle until good contact is
WARNING
●For effective protection in automo- bile accidents and sudden stops, a
child must be properly restrained, using a seat belt or child restraint system which is correctly installed.
For installation details, refer to the operation manual enclosed with the child restraint system. General
installation instruction is provided in this manual.
●Toyota strongly urges the use of a proper child restraint system that conforms to the weight and size of
the child, installed on the rear seat. According to accident statistics, the child is safer when properly
restrained in the rear seat than in the front seat.
●Holding a child in your or someone else’s arms is not a substitute for a child restraint system. In an acci-
dent, the child can be crushed against the windshield or between the holder and the interior of the
vehicle.
■Handling the child restraint sys-
tem
If the child restraint system is not properly fixed in place, the child or
other passengers may be seriously injured or even killed in the event of sudden braking, sudden swerving, or
an accident.
●If the vehicle were to receive a
strong impact from an accident, etc., it is possible that the child restraint system has damage that is
not readily visible. In such cases, do not reuse the restraint system.
●Depending on the child restraint system, installation may be difficult or impossible. In those cases,
check whether the child restraint system is suitable for installment in the vehicle. ( P.49) Be sure to
install and observe the usage rules after carefully reading the child restraint system fixing method in
this manual, as well as the opera- tion manual enclosed with the child restraint system.
●Keep the child restraint system properly secured on the seat even if
it is not in use. Do not store the child restraint system unsecured in the passenger compartment.
●If it is necessary to detach the child restraint system, remove it from the
vehicle or store it securely in the luggage compartment.

■When using a child restraint sys- tem
Observe the following precautions. Failure to do so may result in death or serious injury.
●Never use a rear-facing child restraint system on the front pas-
senger seat when the airbag man- ual on-off switch is on. ( P.43) The force of the rapid inflation of the
front passenger airbag can cause death or serious injury to children in the event of an accident.
●There is a label(s) on the passen-ger side sun visor, indicating it is forbidden to attach a rear-facing
child restraint system to the front passenger seat.Details of the label(s) are shown in

*1: Move the front seat fully rearward. If
the passenger seat height can be
adjusted, move it to the upper most
position.
*2: Adjust the seatback angle to the
most upright position. When install-
ing a forward-facing child seat, if
there is a gap between the child seat
and the seatback, adjust the
seatback angle until good contact is
achieved.

the upper most position.
When securing some types of child
restraint systems in rear seat, 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 effec-
tiveness. 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 seri-
ous injury.
 When installing a child restraint
in the rear seats, adjust the front
seat so that it does not interfere
with the child or child restraint
system.
 When installing a child seat with
support base, if the child seat
interferes with the seatback
when latching it into the support
base, adjust the seatback rear-
ward until there is no interfer-
ence.
