651-1. For safe use

For safety and security
WARNING
■When installing a child restraint system
● 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 a child restraint system with a top tether strap is installed, do not
install the head restraint. The head restraint may interfere with the top
tether strap preventing secure installation of the child restraint system.
● Make sure to properly store the removed head restraint in a secure place
when you use the child restraint system on the rear seat.
● When securing some types of child restraint systems in rear 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 does 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.
■ 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 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 swerve or an accident.

■ Luggage compartment light
The luggage compartment lights turn on when the back door is opened.
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■Before driving
● Make sure that the back door is fully closed. If the back door is not fully
closed, it may open unexpectedly while driving and hit near-by objects or
luggage in the luggage compartment may be thrown out, causing an acci-
dent.
● Do not allow children to play in the luggage compartment.
If a child is accidentally locked in the luggage compartment, they could
have heat exhaustion or other injuries.
● Do not allow a child to open or close the back door.
Doing so may cause the back door to open unexpectedly, or cause the
child’s hands, head, or neck to be caught by the closing back door.
■ Important points while driving
● Keep the back door closed while driving.
If the back door is left open, it may hit near-by objects or luggage in the
luggage compartment may be thrown out, causing an accident.
● Never let anyone sit in the luggage compartment. In the event of sudden
braking or a collision, they are susceptible to death or serious injury.

963-2. Opening, closing and locking the doors
WARNING
■Operating the back door
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in death
or serious injury.
● Remove any heavy loads, such as snow and ice, from the back door
before opening it. Failure to do so may cause the back door to suddenly
shut again after it is opened.
● When opening or closing the back door, thoroughly check to make sure
the surrounding area is safe.
● If anyone is in the vicinity, make sure they are safe and let them know that
the back door is about to open or close.
● Use caution when opening or closing the back door in windy weather as it
may move abruptly in strong wind.
● Do not pull on the back door damper stay to close the back door, and do
not hang on the back door damper stay.
Doing so may cause hands to be caught or the back door damper stay to
break, causing an accident.
● If a bicycle carrier or similar heavy object is attached to the back door, it
may suddenly shut again after being opened, causing someone’s hands,
head or neck to be caught and injured. When installing an accessory part
to the back door, using a genuine Toyota part is recommended.
●The back door may suddenly shut if it is
not opened fully. It is more difficult to
open or close the back door on an
incline than on a level surface, so
beware of the back door unexpectedly
opening or closing by itself. Make sure
that the back door is fully open and
secure before using the luggage com-
partment.
● When closing the back door, take extra
care to prevent your fingers, etc., from
being caught.
● When closing the back door, make sure
to press it lightly on its outer surface. If
the back door handle is used to fully
close the back door, it may result in
hands or arms being caught.

1003-3. Adjusting the seats
WARNING
■When adjusting the seat position
● Take care when adjusting the seat position to ensure that other passen-
gers are not injured by the moving seat.
● Do not put your hands under the seat or near the moving parts to avoid
injury.
Fingers or hands may become jammed in the seat mechanism.
■ Seat adjustment
● Be careful that the seat does not hit passenger or luggage.
● To reduce the risk of sliding under the lap belt during a collision, do not
recline the seat more than necessary.
If the seat is too reclined, the lap belt may slide past the hips and apply
restraint forces directly to the abdomen, or your neck may contact the
shoulder belt, increasing the risk of death or serious injury in the event of
an accident.
Adjustments should not be made while driving as the seat may unexpect-
edly move and cause the driver to lose control of the vehicle.
● After adjusting the seat, make sure that the seat is locked in position.
● Never allow anyone to touch seatback lock release levers while the vehi-
cle is moving.
● If anyone is in the vicinity, make sure they are clear of the seat back path
and let them know that the seat is about to move.
■ After returning the seatback to the upright position
Make sure the seatback is securely locked by pushing it forward and rear-
ward. Failure to do so may result in death or serious injury.
NOTICE
■ To prevent the seat lock mechanism malfunction
Do not use the seatback angle adjustment lever and seatback lock release
lever at the same time. If they are used together, the seat lock mechanism
may be damaged.

1023-3. Adjusting the seats
Pull the seatback lock release
knob and fold the seatback
down.
Each seatback may be folded sep-
arately.
Lift up the seatback until it locks.
Remove the outside seat belt from the seat belt hanger.

Returning the rear seatbacks
WARNING
■When folding the rear seatbacks down
Observe the following precautions. Failure to do so may result in death or
serious injury.
● Do not fold the seatbacks down while driving.
● Stop the vehicle on level ground, set the parking brake and shift the shift
lever to P (automatic transmission) or N (manual transmission).
● Do not allow anyone to sit on a folded seatback or in the luggage compart-
ment while driving.
● Do not allow children to enter the luggage compartment.
● Do not allow anyone to sit on the rear center seat if the rear right seat is
folded down, as the seat belt buckle for the rear center seat belt is th\
en
concealed under the folded seat and cannot be used.
● Be careful not to catch your hand when folding the rear seatbacks.
● If it is necessary to detach the head restraints, remove it from the vehicle
or store it securely in the luggage compartment. This will prevent it from
injuring passengers in the event of sudden braking, sudden swerving or an
accident.
● Depending on the position of the front seat, it may interfere when trying to
fold down the rear seatbacks. If this happens, adjust the position of the
front seat.
