COMFORT ADJUSTMENT For your safety, be sure to always wear your seat belts. The SRS airbag system is designed to activate in response to a severe frontal impact within the shaded area between the arrows in the illustration. The SRS airbags will deploy if the severity of the impact is above the designed threshold level, comparable to an approximate 20 km/h (14 mph) collision when impacting straight into a fixed barrier that does not move or deform. If the severity of the impact is below the above threshold level, the SRS airbags may not deploy. However, this 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 it is involved in an underride collision (a collision in which the nose of the vehicle "underrides", or goes under, the bed of a truck). It is possible with collision severity at the marginal level of airbag sensor detection and activation that only one of your vehicle's two airbags will deploy. The SRS airbags are not designed to inflate if the vehicle is subjected to a side or rear impact, if it rolls over, or if it is involved in a low-speed frontal collision. The airbag sensor assembly consists of a safing sensor and airbag sensor. 66
