A pre-crash safety system containing a radar
sensory system, occupant seat sensor, and an
electric motor-pyrotechnic pretensioner system.
During a pre-collision event, an electric motor in
the pretensioners retracts the slack in the front
seatbelts. When conditions stabilise the electric
motor will reverse itself. When the airbags
deploy, the pyrotechnic pretensioners
function normally.
NOTES:
The front seat side impact airbags and the side
curtain airbags may deploy independently of
each other.
The knee airbags deploy simultaneously with the
frontal airbags and seat belt pretensioners.
WARNING:
The SRS may remain powered for up to 90
seconds after the vehicle is shut off or
disabled. To prevent serious injury or death
from unintentional SRS deployment, avoid
breaching the SRS components
