WARNING
■Child restraint precautions
● For effective protection in automobile accidents and sudden stops, a child
must be properly restrained, using a seat belt or child restrai nt system
depending on the age and size of the child. Holding a child in your arms is
not a substitute for a child restraint system. In an accident, the child can be
crushed against the windshield, or between you and the vehicle’ s interior.
● Vehicles without rear seats: Toyota strongly urges the use of a proper child
restraint system that conforms to the size of the child.
● Vehicles with rear seats: Toyota strongly urges the use of a proper child
restraint system that conforms to the size of the child, instal led on the rear
seat. According to accident statistics, the child is safer when properly
restrained in the rear seat than in the front seat.
● Never install a rear-facing child restraint system on the front passenger
seat even if the “AIR BAG OFF” i ndicator 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-fac-
ing child restraint system is installed on the front passenger seat.
● Vehicles without rear seats: A forward-facing child restraint s ystem may be
installed on the front passenger seat only when it is unavoidab le. Adjust
the seatback as upright as possible and always move the seat as far back
as possible even if the “AIR BAG OFF” indicator light is illumi nated,
because the front passenger airbag could inflate with considerable speed
and force. Otherwise, the child may be killed or seriously injured.
● Vehicles with rear seats: A forward-facing child restraint syst em 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. Adjust the seatback as upright as possible and always
move the seat as far back as possible even if the “AIR BAG OFF” indicator
light is illuminated, because the front passenger airbag could inflate with
considerable speed and force. Otherwise, the child may be kille d or seri-
ously injured.

621-1. For safe use
With flexible lower attachments
Widen the gap between the seat cushion and seatback slightly.
Latch the hooks of the lower
attachments onto the LATCH

has a top tether strap, the top
tether strap should be latched
onto the top tether strap anchor.

The symbol on a child restraint
system indicates the presence of a
lower connector system.
With rigid lower attachments
Widen the gap between the seat cushion and seatback slightly.
Latch the buckles onto the
LATCH anchors. If the child
restraint has a top tether strap,

■Laws and regulations pertaining to anchorages
The LATCH system conforms to FMVSS225 or CMVSS210.2.
Child restraint systems conforming to FMVSS213 or CMVSS213 specifica-
tions can be used.
This vehicle is designed to conform to the SAE J1819.
WARNING
■ When installing a booster seat
To prevent the belt from going into ALR lock mode, do not fully extend the
shoulder belt. ALR mode causes the belt to tighten only. This could cause
injury or discomfort to the child. ( P. 32)
■ When installing a child restraint system
Follow the directions given in the child restraint system insta llation manual
and fix the child restraint system securely in place.
If the child restraint system is not correctly fixed in place, the child or other
passengers may be seriously injured or even killed in the event of a sudden
braking or an accident.
● Vehicles with rear seats: If the driver’s
seat interferes with the child restraint
system and prevents it from being
attached correctly, attach the child
restraint system to the right-hand rear
seat.
● Vehicles with rear seats: Adjust the front
passenger seat so that it does not inter-
fere with the child restraint system.
● Only put a forward-facing child restraint
system on the front seat when unavoid-
able. When installing a forward-facing
child restraint system on the front pas-
senger seat, move the seat as far back
as possible even if the “AIR BAG OFF”
indicator light is illuminated. Failure to
do so may result in death or serious
injury if the airbags deploy (inflate).

Exhaust gas precautions
Harmful substance to the human body is included in exhaust
gases if inhale.
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 to enter the vehicle a nd may lead
to an accident caused by light-headedness, or may lead to death or a serious
health hazard.
■ Important points while driving
● Vehicles with a sliding type back window: Keep the back window closed.
● If you smell exhaust gases in the vehicle even when the back window
(vehicles with a sliding type) is closed, open the windows and have the
vehicle inspected at your Toyota dealer as soon as possible.
● Toyota does not recommend occupying the rear cargo area when it is fitted
with a slide-in camper, camper shell or other type cover while the engine is
running. This caution applies to both driving and stopped, or parked situa-
tions with the engine running. Particular care should be taken to prevent
exhaust gases from entering camper bodies, trailers or other enclosures
on or around your vehicle. If exhaust fumes are detected, open all win-
dows and thoroughly ventilate the area.
■ When parking
● If the vehicle is in a poorly ventilated 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 vehicle.
■ 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.
