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. 34)

When installing a child restraint system
Follow the directions given in the child restraint system installation 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 sudden
braking, sudden swerving or an accident.

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.

Adjust the front passenger seat or sec-
ond seats so that it does not interfere
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).

WARNING

When installing a child restraint system

When installing a child restraint system on the third center seat, adjust
both seatbacks at the same angle. Otherwise, the child restraint system
cannot be securely restrained and this may cause death or serious injuries
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 (8-passen-
ger models) or third row 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 dose 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

When installing a child restraint system to the AUTO ACCESS SEAT
(if equipped)

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 restraint 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 a sudden braking, sudden swerving or an accident.

Do  not  operate  the  AUTO  ACCESS
SEAT  while  a  child  restraint  system  is
fixed  to  the  seat  by  the  child  restraint
lock function belt.
If you force the seat operation, the seat,
seat  belt  or  child  restraint  system  may
be damaged, or may cause an injury.

If a child restraint system is fixed to the
AUTO ACCESS SEAT by the LATCH
system, be careful that the child’s head,
hands and legs do not hit the body of
the vehicle when operating the seat.
Injuries may be caused.

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 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 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 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.
