GENERAL
A three point safety belt is installed at each seat position.
Except in North American Specification (NAS) markets, all of the safety belts
have Emergency Locking Retractors (ELR). In NAS markets, only the driver seat is
fitted with an ELR; all of the passenger safety belts have Automatic Locking
Retractors (ALR).
Both types of retractor 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.
The ALR has a mode of
operation where the retractor will take up slack in the webbing, but not allow
any slack to be paid out. This mode of operation can be used to secure a child
seat.
- To engage the ALR child seat mode of operation: Pull the webbing
out of the retractor to its full extent.
- To cancel the ALR child seat mode of operation: Allow the retractor
to fully rewind the webbing.
A safety belt warning indicator is
installed in the instrument cluster to remind the front seat occupants to fasten
their safety belts. On NAS vehicles, when the ignition switch is turned to
position II, the warning indicator illuminates if the safety belt of an occupied
front seat is not fastened. The warning indicator remains illuminated until the
safety belt of each occupied front seat is fastened, or the ignition is switched
off. In all markets except NAS, a belt minder function provides a more intrusive
reminder to fasten the front safety belts.
FRONT SAFETY BELTS
The retractor of each front safety belt is attached
to the related B pillar. The webbing runs from the retractor through an upper
mounting, attached to a shoulder height adjuster on the B pillar, to an anchor
point on the front seat.
On NAS vehicles, a tension sensor is integrated
into the anchor point of the passenger front safety belt. The tension sensor is
part of the occupant classification system.
Air Bag and Safety Belt Pretensioner Supplemental Restraint System
(SRS) (501-20B Supplemental Restraint System)
The retractor
for each front safety belt incorporates a load limiter that allows the retractor
reel to partially unwind when the load on the webbing exceeds a predetermined
limit.
The buckle for each front safety belt is attached to a
pretensioner secured to the inboard side of the related front seat frame. Each
buckle incorporates a safety belt buckle sensor that provides a status input to
the restraints control module, which uses the input to determine the air bag and
pretensioner activation strategies. The restraints control module also relays
the status of the safety belts to the instrument cluster on the high speed CAN
bus.
Belt Minder Function (Where Fitted)
The belt minder function provides
warnings to the driver if the appropriate front safety belts are not fastened
when driving. The belt minder function is controlled by the instrument cluster
using medium speed CAN bus messages, from the restraints control module, to
monitor the status of the front safety belts.
When the ignition switch is
turned to position II, the instrument cluster illuminates the safety belt
warning indicator until one of the front safety belts is fastened or the belt
minder function is triggered. The belt minder function is triggered when the
ignition switch is in position II and the following conditions
coexist:
- The belt minder function is enabled.
- Vehicle speed is 8 km/h (5 mph) or more.
- The vehicle is not in reverse.
- The driver safety belt or, if the front passenger seat is occupied, the
front passenger safety belt, is unfastened.
When the belt minder is
triggered, the instrument cluster generates the following warnings for 10
seconds.
- Flashes the safety belt warning indicator at 2 Hz.
- Sounds a repeating chime in sequence with the flashing safety belt warning
indicator.
After 10 seconds, the repeating chime is discontinued and
the safety belt warning indicator changes from flashing to continuously
illuminated. While the trigger conditions still coexist, the warnings are
repeated every 30 seconds until one of the following
occurs:
- 5 minutes has elapsed from when the warnings were first triggered.
- The safety belt of each occupied front seat is fastened.
- The ignition switch is turned to position 0.
- The vehicle speed decreases to 5 km/h (3 mph).
The belt minder
function can be enabled and disabled using the driver safety belt switch. The
instrument cluster changes the state of the belt minder function if, within 60
seconds of first turning the ignition switch to position II, the driver safety
belt is fastened and unfastened nine times. Successful completion of the change
is indicated by a single chime and the safety belt warning indicator flashing
five times, at 2 Hz. The belt minder function can also be enabled and disabled
using T4.

SECOND ROW SAFETY BELTS
The retractor of each outboard second row safety
belt is attached to the body immediately behind the D pillar. The webbing runs
from the retractor, through an upper mounting on the D pillar, to an anchor
point at the front of the related wheel arch.
The retractor for the
center second row safety belt is installed in the top of the seat back. The
webbing runs from the retractor, over the top of the seat, to an anchor point at
the base of the seat frame.
The buckles for the second row safety belts
are attached to the related seat frame.
THIRD ROW SAFETY BELTS (WHERE FITTED)
The retractor of each third row
safety belt is attached to the E pillar. The webbing runs from the retractor,
through a mounting on the E pillar to an anchor point on the floor.
The
buckles for the third row safety belts are attached to the related seat
frame.
