Adaptive Steering Column (XC90 USA/CDN Only)
Never use an ohmmeter or similar tool to test airbags, inflatable curtains, the adaptive steering column or seat belt tensioners. Disconnect airbags, inflatable curtains, the adaptive steering column or seat belt tensioners before testing them. Failure to do so may result in accidental deployment. This could result in serious injury or death.
When the adaptive steering column in the collision protection system is activated, a pin is deployed which makes the steering column longitudinally adjustable and thus collapsible. If the frontal collision exceeds a certain level the steering wheel is pressed into the dashboard to a greater degree than if the steering column were rigid.
The steering is not affected by the deployment of the pin. The pin is deployed by a pyrotechnical charge and is located in the center of the steering column. The collision protection system in the adaptive steering column only functions if the driver is wearing the seatbelt and if the airbag deploys. The entire steering column must be replaced if the collision protection system in the adaptive steering column has deployed.
