Seat belts— —Seat belt precautions Toyota strongly urges that the driver and passengers in the vehicle be properly re- strained at all times with the seat belts provided. Failure to do so could increase the chance of injury and/or the severity of injury in accidents. The seat belts provided for your vehicle are designed for people of adult size, large enough to properly wear them. Child. Use a child restraint system ap- propriate for the child until the child be- comes large enough to properly wear the vehicle’s seat belts. See “Child restraint” on page 96 in this Section for details. If a child is too large for a child restraint system, the child should sit in the rear seat and must be restrained using the vehicle’s seat belt. According to accident statistics, the child is safer when properly restrained in the rear seat than in the front seat. If a child must sit in the front seat, the seat belts should be worn properly. If an accident occurs and the seat belts are not worn properly, the force of the rapid infla- tion of the airbag may cause death or serious injury to the child.


Do not allow any children to stand up or kneel on either rear or front seats. An unrestrained child could suffer serious in- jury or death during emergency braking or a collision. Also, do not let the child sit on your lap. Holding a child in your arms does not provide sufficient restraint. Pregnant woman. Toyota recommends the use of a seat belt.

CAUTION


D The SRS front airbag system is de- signed only as a supplement to the primary protection of the driver and front passenger seat belt systems. The driver and front passenger can be killed or seriously injured by the inflating airbags if they do not wear the available seat belts properly. During sudden braking just before a collision, an unrestrained driver or front passenger can move for- ward into direct contact with or close proximity to the airbag which may then deploy during the colli- sion. To ensure maximum protection in an accident, the driver and all passengers the vehicle must wear their seat belts properly. Wear- ing a seat belt properly during an accident reduces the chances of death or serious injury or being thrown out of the vehicle.

The SRS front airbags are not generally designed to inflate if the vehicle is in- volved in a side or rear collision, if it rolls over, or if it is involved in a low− speed frontal collision. But, whenever a collision of any type causes sufficient forward deceleration of the vehicle, de- ployment of the SRS front airbags may occur.


The SRS front airbags may also deploy if a serious impact occurs to the under- side of your vehicle. Some examples are shown in the illustration.


The SRS front airbags are designed to deploy in severe (usually frontal) colli- sions where the magnitude and duration of the forward deceleration of the ve- hicle exceeds the designed threshold level. The SRS front airbags will deploy if the severity of the impact is above the de- signed threshold level, comparable to an approximate 25 km/h (15 mph) collision when the vehicle has the impact straight into a fixed barrier that does not move or deform. However, threshold velocity will be considerably higher if the vehicle strikes an object, such as a parked vehicle or sign pole, which can move or deform on impact, or if the vehicle is involved in an underride collision in which the front of the vehicle “underrides”, or goes under, the bed of a truck, etc.). It in some collisions where the forward deceleration of the ve- hicle is very close to the designed thresh- old level, the SRS front airbags and the seat belt pretensioners may not activate together. Always wear your seat belts properly.

The airbag sensor assembly consists of a safing sensor and airbag sensor. The front airbag sensors constantly moni- tor the forward deceleration of the vehicle. If an impact results in a forward decelera- tion beyond the designed threshold level, the system triggers the airbag inflators. At this time a chemical reaction in the infla- tors very quickly the airbags with non−toxic gas to help restrain the forward motion of the occupants. The front airbags then quickly deflate, so that there is no obstruction of the driver’s vision should it be necessary to continue driving. When the airbags inflate, they produce a loud noise and release some smoke and residue along with non−toxic gas. This does not indicate a fire. This smoke may remain inside the vehicle for some time, and may cause some minor irritation to the eyes, skin or breathing. Be sure to wash off any residue as soon as possible to prevent any potential skin irritation with soap and water. If you can safely exit from the vehicle, you should do so imme- diately.

injuries, especially


Deployment of the airbags happens in a fraction of a second, so the airbags must inflate with considerable force. While the system is designed to reduce serious inju- ries, primarily to the head and chest, it may also cause other, less severe injuries to the face, chest, arms and hands. These are usually in the nature of minor burns or abrasions and swelling, but the force of a deploying airbag can cause more seri- ous if an occupant’s hands, arms, chest or head is in close proximity to the airbag module at the time of deployment. This is why it is important for to: avoid placing any object or part of the body between the occupant and the airbag module; sit straight and well back into the seat; wear the available seat belt properly; and sit as far as possible from the airbag module, while still maintaining control of the ve- hicle. Parts of the airbag module (steering wheel hub, airbag cover and inflator) may be hot for several minutes after deployment, so do not inflate only once. The windshield may be damaged by absorbing some of the force of the inflat- ing airbag.

(This function can be turned off if inflation is not desired. See “Roll sensing of curtain shield airbags off switch” on page 95 in this Section.) The SRS curtain shield airbags may acti- vate even when the side airbags are not activated. Always wear your seat belt properly.

To ensure maximum protection in an accident, the driver and all passen- gers in the vehicle must wear their seat belts properly. Wearing a seat belt properly during an accident reduces the chances of death or serious injury or being thrown out of the vehicle. For instructions and precautions concerning the seat belt system, see “Seat belts” on page 64 in this Section.

SRS side airbags and curtain shield airbags considerable force. To reduce the possibility of death or serious injury when they in- flate, the driver, front passenger and rear/second passengers must: D Wear their seat belts properly. D Remain properly seated with their backs upright and against the seats at all times.


Improper sitting and wearing of the seat belts may not retain you inside the vehicle.


When the airbags inflate, they produce a fairly loud noise and release some smoke and residue along with non−toxic gas. This does not indicate a fire. This smoke may remain inside the vehicle for some time, and may cause some minor irritation to the eyes, skin or breathing. Be sure to wash off any residue as soon as possible to prevent any potential skin irritation with soap and water. If you can safely exit from the vehicle, you should do so imme- diately. Deployment of the airbags happens in a fraction of a second, so the airbags must inflate with considerable force. While the system is designed to reduce serious inju- ries, it may also cause minor burns or abrasions and swelling. Front seats as well as parts of the front and rear pillars, front, center and rear garnish and roof interior may be hot for several minutes, but them- selves will not be hot. The airbags are designed to inflate only once.
