Roll Over

The MRS system does not specifically detect roll over conditions, but if as a consequence of the crash situation the system front or side trigger thresholds are exceeded, the relevant airbags and front seat belt pre-tensioners are deployed.

Workshop Hint 

After repair of damage caused by a collision in which the airbag(s) did not deploy, the integrity of the MRS system must be checked using GT1.

Workshop Hint 

Following deployment of the MRS within the vehicle, under any circumstances, all system components must be replaced.
