301-1. For safe use
Make sure that all occupants are
wearing their seat belts before
driving the vehicle. (P.32)
Use a child restraint system
appropriate for the child until the
child becomes large enough to properly wear the vehicle’s seat
belt. (
P.51)

WARNING
Observe the following precau-
tions.
Failure to do so may result in
death or serious injury.
●Do not adjust the position of the
driver’s seat while driving.
Doing so could cause the driver
to lose control of the vehicle.
●Do not place a cushion between
the driver or passenger and the
seatback. A cushion may pre-
vent correct posture from being
achieved, and reduce the effec-
tiveness of the seat belt and
head restraint.
●Do not place anything under the
front seats.
Objects placed under the front
seats may become jammed in
the seat tracks and stop the
seat from locking in place. This
may lead to an accident and the
adjustment mechanism may
also be damaged.
●Always observe the legal speed
limit when driving on public
roads.
●When driving over long dis-
tances, take regular breaks
before you start to feel tired.
Also, if you feel tired or sleepy
while driving, do not force your-
self to continue driving and take
a break immediately.

belt. ( P.51)
●When the child becomes large
enough to properly wear the vehi-
cle’s seat belt, follow the instruc-
tions regarding seat belt usage.
( P.31)
■Seat belt extender
If your seat belts cannot be fastened
securely because they are not long
enough, a personalized seat belt
extender is available from your
Toyota dealer free of charge.
WARNING
●Inspect the seat belt system
periodically. Check for cuts,
fraying, and loose parts. Do not
use a damaged seat belt until it
is replaced. Damaged seat belts
cannot protect an occupant
from death or serious injury.
●Ensure that the belt and plate
are locked and the belt is not
twisted.
If the seat belt does not function
correctly, immediately contact
your Toyota dealer.
●Replace the seat assembly,
including the belts, if your vehi-
cle has been involved in a seri-
ous accident, even if there is no
obvious damage.
●Do not attempt to install,
remove, modify, disassemble or
dispose of the seat belts. Have
any necessary repairs carried
out by your Toyota dealer. Inap-
propriate handling may lead to
incorrect operation.
Correct use of the seat

WARNING
■Using a seat belt extender
Observe the following precautions
to reduce the risk of injury in the
event of sudden braking, sudden
swerving or an accident.

1
For safety and security
1To fasten the seat belt, push
the plate into the buckle until a click sound is heard.
2 To release the seat belt,
press the release button .
■Emergency locking retractor
(ELR)
The retractor will lock the belt during
a sudden stop or on impact. It may
also lock if you lean forward too
quickly. A slow, easy motion will
allow the belt to extend so that you
can move around fully.
■Automatic locking retractor
(ALR)
When a passenger’s shoulder belt is
completely extended and then
retracted even slightly, the belt is
locked in that position and cannot
be extended. This feature is used to
hold a child restra int system (CRS)
firmly. To free the belt again, fully
retract the belt and then pull the belt
out once more.
1 Push the seat belt shoulder
anchor down while pressing
the release button .
2 Push the seat belt shoulder
anchor up while pressing the
release button .
WARNING
●Do not wear the seat belt
extender if you can fasten the
seat belt without the extender.
●Do not use the seat belt
extender when installing a child
restraint system because the
belt will not securely hold the
child restraint system, increas-
ing the risk of death or serious
injury in the event of an acci-
dent.
●The personalized extender may
not be safe on another vehicle,
when used by another person,
or at a different seating position
other than the one originally
intended.
NOTICE
■When using a seat belt
extender
When releasing the seat belt,

Riding with children
Observe the following pre-
cautions when children are
in the vehicle.
Use a child restraint system
appropriate for the child,
until the child becomes
large enough to properly
wear the vehicle’s seat belt.
It is recommended that chil-
dren sit in the rear seats to
avoid accidental contact
with the shift lever, wiper
switch, etc.
 Use the rear door child-pro-
tector lock or the window
lock switch to avoid children
opening the door while driv-
ing or operating the power
window accidentally.
( P.189, 229)
 Do not let small children
operate equipment which
may catch or pinch body
parts, such as the power
window, hood, back door,
seats, etc.
WARNING
■When children are in the vehi-
cle
Never leave children unattended
in the vehicle, and never allow
children to have or use the key.
Children may be able to start the
vehicle or shift the vehicle into
neutral. There is also a danger
that children ma y injure them-
selves by playing with the side
windows or other features of the
vehicle. In addition, heat build-up
or extremely cold temperatures
inside the vehicle can be fatal to
children.

■Installing child restraint
system using a seat belt
(child restraint lock func-
tion belt)
Install the child restraint system
in accordance to the operation
WARNING
●A forward-facing child restraint
system may be installed on the
front passenger seat only when
it is unavoidable. When install-
ing a forward-facing child
restraint system on the front
passenger seat, adjust the seat-
back angle to the most upright
position, move the seat to the
rearmost position, even if the
“PASSENGER AIR BAG OFF”
indicator light is illuminated.
If the head restraint interferes
with the child restraint system
installation and the head
restraint can be removed,
remove the head restraint.
●Do not allow the child to lean
his/her head or any part of
his/her body against the door or
the area of the seat, front or rear
pillars, or roof side rails from
which the SRS side airbags or
SRS curtain shield airbags
deploy even if the child is
seated in the child restraint sys-
tem. It is dangerous if the SRS
side and curtain shield airbags
inflate, and the impact could
cause death or serious injury to
the child.
●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.
●Use a child restraint system
suitable to the age and size of
the child and install it to the rear
seat.
●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
so that it does not interfere with
the child restraint system.

stowing position.
WARNING
■When installing a child
restraint system
Observe the following precau-
tions.
Failure to do so may result in
death or serious injury.
●Do not allow children to play
with the seat belt. If the seat belt
becomes twisted around a
child’s neck, it may lead to
choking or other serious injuries
that could result in death.
If this occurs and the buckle
cannot be unfastened, scissors
should be used to cut the belt.
●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.
●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,
