The seat belts provide maximum protection in a frontal or rear collision when the passengers are sitting up straight and well back in the seats. If you are reclined, the lap belt may slide past your hips and apply restraint forces directly to the abdomen or your neck may contact the shoulder belt. In the event of a frontal colli- sion, the more the seat is reclined, the greater the risk of death or per- sonal injury.

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 127 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.

When a passenger’s shoulder belt is com- pletely extended and retracted even slightly, the belt is locked in that position and cannot be extended. This fea- ture is used to hold the child restraint system securely. (For details, see “Child restraint” on page 127 in this Section.) To free the belt again, fully retract the belt and then pull the belt out once more. If the seat belt cannot be pulled out of the retractor, firmly pull the belt and release it. You will then be able to smoothly pull the belt out of the retractor.

To connect the extender to the seat belt, insert the tab into the seat belt buckle so that the “PRESS” signs on the buckle release buttons of the ex- tender and the seat belt are both facing outward as shown. You will hear a click when the tab locks into the buckle. When releasing the seat belt, press on the buckle release button on the extender, not on the seat belt. This helps prevent damage to the vehicle interior and extend- er itself.

CAUTION

D After inserting the tab, make sure the tab and buckle are locked and that the lap and shoulder portions of the belt and the seat belt extend- er are not twisted.

D Do not insert coins, clips, etc. in the buckle as this may prevent you from properly latching the tab and buckle.

D If the seat belt does not function normally, immediately contact your Toyota dealer. Do not use the seat until the seat belt is fixed, because it cannot protect an adult occupant or your child from injury.

The driver and front passenger seat belt pretensioners are designed to be activated in response to a severe fron- tal impact. When the sensor detects a severe frontal impact, the front seat belts are quickly drawn back by the retractors so that the belts snugly restrain the occupants.

The SRS (Supplemental Restraint Sys- tem) front airbags are designed to pro- vide further protection for the driver and front passenger in addition to the primary safety protection provided by the seat belts. In response to a severe frontal impact, the SRS front airbags work together with the seat belts to help reduce injury by inflating. The SRS front airbags help re- duce injuries mainly to the driver’s or front passenger’s head or chest caused by hit- ting the vehicle interior.

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.

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 SRS front airbags are generally not 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.

fills

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 im- mediately.

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.

The SRS side airbag on the passenger seat will not activate if there is no pas- senger sitting in the front passenger seat. However, the side airbag on the passen- ger seat may deploy if luggage is put on the seat, or the seat belt is buckled up regardless of the presence of the occu- pant in the seat. (As for the front passen- ger occupant classification system, see “—Front passenger occupant classification system” on page 123 in this Section.) The SRS curtain shield airbag on the pas- senger side are activated even with no passenger in the front seat or all window− side seat.
