Seat Belt Pretensioner
The front seat belt system is equipped with
pretensioning devices that are designed to re-
move slack from the seat belt in the event of a
collision. These devices may improve the per-
formance of the seat belt by removing slack
from the seat belt early in a collision. Preten-
sioners work for all size occupants, including
those in child restraints.
NOTE:
These devices are not a substitute for proper
seat belt placement by the occupant. The seat
belt still must be worn snugly and positioned
properly.
The pretensioners are triggered by the Occu-
pant Restraint Controller (ORC). Like the air
bags, the pretensioners are single use items. A
deployed pretensioner or a deployed air bag
must be replaced immediately.
Energy Management Feature
The front seat belt system is equipped with an
Energy Management feature that may help fur-
ther reduce the risk of injury in the event of a
collision. The seat belt system has a retractor
assembly that is designed to release webbing in
a controlled manner.
Switchable Automatic Locking Retractors
(ALR) — (If Equipped)
The seat belts in the passenger seating posi-
tions may be equipped with a Switchable Auto-
matic Locking Retractor (ALR) which is used to
secure a child restraint system. For additional
information, refer to “Installing Child Restraints
Using The Vehicle Seat Belt” under the “Child
Restraints” section of this manual. The figure
below illustrates the locking feature for each
seating position.
If the passenger seating position is equipped
with an ALR and is being used for normal usage,
only pull the seat belt webbing out far enough to
comfortably wrap around the occupant’s mid-
section so as to not activate the ALR. If the ALR
is activated, you will hear a clicking sound as the
seat belt retracts. Allow the webbing to retract
completely in this case and then carefully pull
out only the amount of webbing necessary to
comfortably wrap around the occupant’s mid-
section. Slide the latch plate into the buckle until
you hear a
" click. "
In Automatic Locking Mode, the shoulder belt is
automatically pre-locked. The seat belt will still
retract to remove any slack in the shoulder belt.
Use the Automatic Locking Mode anytime a
child restraint is installed in a seating position
that has a seat belt with this feature. Children
12 years old and under should always be prop-
erly restrained in a vehicle with a rear seat.
WARNING!
•
NEVER use a rearward facing child re-
straint on a seat protected by an ACTIVE
AIRBAG in front of it, DEATH or SERIOUS
INJURY to the CHILD can occur.
•
Only use a rear-facing child restraint in a
vehicle with a rear seat.
•
A deploying passenger front air bag can
cause death or serious injury to a child
12 years or younger, including a child in a
rear-facing child restraint.
How To Engage The Automatic Locking Mode
1. Buckle the combination lap and shoulder
belt.
2. Grasp the shoulder portion and pull down-
ward until the entire seat belt is extracted.
3. Allow the seat belt to retract. As the seat belt
retracts, you will hear a clicking sound. This
indicates the seat belt is now in the Auto-
matic Locking Mode.
