SIENNA_U (OM45477U)
CAUTION
■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.
● Push and pull the child restraint system from side to side and forward to be
sure it is secure.
● After securing a child restraint system, never adjust the seat.
● Follow all installation instructions provided by the child restraint system
manufacturer.

CAUTION
■
When installing a child restraint s ystem 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 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. 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.

CAUTION
■When the vehicle is parked
● Always apply the parking brake, shift the shift lever to P, stop the engine
and lock the vehicle.
Do not leave the vehicle unattended while the engine is running.
● Do not touch the exhaust pipe while the engine is running or immediately
after turning the engine off.
Doing so may cause burns.
● 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. This may lead
to death or a serious health hazard.
■ Exhaust gases
Exhaust gases include harmful carbon monoxide (CO), which is colorless
and odorless. Inhaling exhaust gases may lead to death or a serious health
hazard.
● If the vehicle is in a poorly ventilated area, stop the engine. In a closed
area, such as a garage, exhaust gases may collect and enter the vehicle.
This may lead to death or a serious health hazard.
● The exhaust system should be checked occasionally. 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.
Failure to do so may allow exhaust gases to enter the vehicle, resulting in
death or a serious health hazard.
