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.
How To Disengage The Automatic Locking
Mode
Unbuckle the combination lap/shoulder belt and
allow it to retract completely to disengage the
Automatic Locking Mode and activate the ve-
hicle sensitive (emergency) locking mode.
WARNING!
• The seat belt assembly must be replaced if
the switchable Automatic Locking Retrac-
tor (ALR) feature or any other seat belt
function is not working properly when
checked according to the procedures in the
Service Manual.
• Failure to replace the seat belt assembly
could increase the risk of injury in colli-
sions.
WARNING! (Continued)
• Do not use the Automatic Locking Mode to
restrain occupants who are wearing the
seat belt or children who are using booster
seats. The locked mode is only used to
install rear-facing or forward-facing child
restraints that have a harness for restrain-
ing the child.
Supplemental Active Head Restraints (AHR)
These head restraints are passive, deployable
components, and vehicles with this equipment
cannot be readily identified by any markings,
only through visual inspection of the head re-
straint. The head restraint will be split in two
halves, with the front half being soft foam and
trim, the back half being decorative plastic.
How The Active Head Restraints (AHR) Work
The Occupant Restraint Controller (ORC) deter-
mines whether the severity or type of rear
impact will require the Active Head Restraints
(AHR) to deploy. If a rear impact requires de-
ployment, both the driver and front passenger
seat AHRs will be deployed.
When AHRs deploy during a rear impact, the
front half of the head restraint extends forward
to minimize the gap between the back of the
occupant's head and the AHR. This system is
designed to help prevent or reduce the extent of
injuries to the driver and front passenger in

certain types of rear impacts.
NOTE:
The Active Head Restraints (AHR) may or may
not deploy in the event of a front or side impact.
However, if during a front impact, a secondary
rear impact occurs, the AHR may deploy based
on the severity and type of the impact.
