75-10 DESCRIPTION AND OPERATION
SRS warning lamp
The SRS warning lamp illuminates for 5 seconds during system readiness check on starting the engine. The SRS
warning lamp extinguishes for one second after the system readiness check is performed. If a fault is present the
warning lamp then illuminates continuously. If no fault is present, the SRS warning lamp remains extinguished. If a
system fault occurs in excess of two seconds after the readiness check has been completed, the SRS warning lamp
illuminates for that ignition cycle. It remains illuminated for a minimum of 12 seconds
± 4 seconds for all fault
conditions.
The SRS warning lamp will only illuminate for low voltage concerns while the low voltage condition is present. If the
low voltage condition is corrected, the SRS warning lamp extinguishes and the fault is recorded in the DCU's memory.

DESCRIPTION AND OPERATION 75-11
DESCRIPTION AND OPERAT ION
Description - seat belts
An inertia reel, three point seat belt is installed at each seat position. The inertia reels incorporate a liftshaft locking
system with webbing sensor and car sensor activating mechanisms. The webbing sensor activates the locking system
if the webbing is subjected to a sharp pull. The car sensor activates the locking system if the vehicle is subjected to
sudden deceleration or a severe tilt angle.
Front seat belts
The inertia reel of each front seat belt is attached to the related B/C post, behind the finishers. The webbing runs from
the inertia reel, through a height adjuster, to an anchor point at the base of the B/C post. The buckle assembly for
each belt is attached to the inboard side of the seat and contains the SRS pretensioner.
Rear seat belts
The inertia reels for the outboard rear seats are attached to the body behind the loadspace side trim casings. The
webbing runs from each inertia reel through an upper mounting, suspended from the cantrail, to an anchor point on
the rear wheel arch.
The inertia reel of the centre rear seat is mounted in the back of the seat. The webbing runs through a guide on the
top of the seat and is anchored to one of the seat hinge points. The buckles for the rear seat belts are also attached
to the seat hinge points.
Third row seat belts
The inertia reel of each third row rear seat belt is attached to the related E post, behind the loadspace side trim
casing.The webbing runs from the inertia reel, through an upper mounting on the E post to an anchor point on the
loadspace floor. The buckle is mounted on the inboard side of the seat.
