WARNING
■SRS airbag precautions
● Do not hang coat hangers or other hard objects on the coat hook s. All of
these items could become projectiles and may cause death or ser ious
injury, should the SRS curtain shield airbags deploy.
● If a vinyl cover is put on the area where the SRS knee airbag w ill deploy,
be sure to remove it.
● Do not use seat accessories which cover the parts where the SRS side
airbags inflate as they may interfere with inflation of the air bags. Such
accessories may prevent the side airbags from activating correc tly, disable
the system or cause the side airbags to inflate accidentally, r esulting in
death or serious injury.
● Do not strike or apply significant levels of force to the area of the SRS air-
bag components.
Doing so can cause the SRS airbags to malfunction.
● Do not touch any of the component parts immediately after the S RS air-
bags have deployed (inflated) as they may be hot.
● If breathing becomes difficult after the SRS airbags have deplo yed, open a
door or window to allow fresh air in, or leave the vehicle if i t is safe to do
so. Wash off any residue as soon as possible to prevent skin ir ritation.
● If the areas where the SRS airbags are stored, such as the steering wheel
pad and front and rear pillar garnishes, are damaged or cracked , have
them replaced by your Toyota dealer.
● Do not place anything, such as a cushion, on the front passenge r's seat.
Doing so will disperse the passenger's weight, which prevents t he sensor
from detecting the passenger's weight properly. As a result, th e SRS front
airbags for the front passenger may not deploy in the event of a collision.
●Vehicles without a smart key system:
Do not attach any heavy, sharp or hard
objects such as keys and accessories
to the key. The objects may restrict the
SRS knee airbag inflation or be thrust
into the driver's seat area by the force of
the deploying airbag, thus causing a
danger.

521-1. For safe use
4RUNNER (U)
●It is recommended that children sit in the rear seats to avoid acci-
dental contact wit h the shift lever, wiper switch etc.
● Use the rear door child-protector lock or the window lock switc h to
avoid children opening the door while driving or operating the
power window accidentally.
● Do not let small children operate equipment which may catch or
pinch body parts, such as the power window, hood, back door,
seats etc.
Safety information for children
Observe the following precautions when children are in the vehi -
cle.
Use a child restraint system app ropriate for the child, until the
child becomes large enough to properly wear the vehicle’s seat
belt.
WARNING
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 may injure themselves by p laying with
the windows, the moon roof or other features of the vehicle. In addition, heat
build-up or extremely cold temperatures inside the vehicle can be fatal to
children.
