The Subaru Ascent is equipped with an advanced SRS frontal airbag system engineered to provide effective protection during specific types of collisions. The driver's and front passenger's SRS frontal airbags are carefully calibrated to deploy only under conditions where additional protection beyond seatbelts is necessary.
The Subaru Ascent frontal airbag system is designed with the following operational characteristics:
However, the Subaru Ascent SRS frontal airbags are not intended to operate under the following conditions:
*1: In such cases, the seatbelt system alone usually provides sufficient protection.
*2: Frontal airbag deployment would not effectively protect occupants in these types
of impacts.
The deployment of the Subaru Ascent airbags depends on the actual force transmitted to the passenger compartment during a crash. It is important to note that visible damage to the vehicle may not accurately reflect the level of force experienced by occupants.
Example of accident in which the driver's/driver's and front passenger's SRS frontal airbag(s) will most likely deploy

In the Subaru Ascent, a direct head-on collision with a rigid object such as a concrete barrier at speeds of approximately 12 to 19 mph (20 to 30 km/h) or higher will typically result in deployment of the driver’s airbag or both driver and front passenger airbags. Similar frontal impacts with equivalent force characteristics may also trigger deployment.
Examples of the types of accidents in which it is possible that the driver's/driver's and front passenger's SRS frontal airbag(s) will deploy

In certain Subaru Ascent scenarios, airbags may deploy even without a classic frontal collision. For example, a strong impact to the underside of the vehicle—such as dropping into a deep pothole, hitting a curb, or striking a road obstacle—can generate sufficient force to activate the system.
Examples of the types of accidents in which deployment of the driver's/driver's and front passenger's SRS frontal airbag(s) is unlikely to occur

In these types of collisions, the Subaru Ascent SRS frontal airbags may or may not deploy depending on the magnitude and direction of the impact forces transmitted to the cabin.
Examples of the types of accidents in which the driver's/driver's and front passenger's SRS frontal airbag(s) are not designed to deploy in most cases

The Subaru Ascent frontal airbags are generally not designed to deploy in the following situations:

In the Subaru Ascent, SRS airbags are designed for single deployment only. In multi-impact accidents, such as when the vehicle first collides with another car and then hits a fixed object like a wall, the airbags will deploy only during the initial impact event.
For example, if the Subaru Ascent experiences a double collision, the system will activate the airbags during the first significant impact. Once deployed, the airbags will not activate again during subsequent impacts within the same event.
Understanding how and when the Subaru Ascent SRS airbag system activates helps drivers and passengers better appreciate its role in vehicle safety and reinforces the importance of proper seatbelt use in all driving conditions.
