Seating and Safety Restraints
2. Grasp the shoulder portion and
pull downward until the entire belt
is extracted.
3. Allow the belt to retract. As the belt retracts, you will hear a clicking
sound. This indicates the safety belt is now in the automatic locking
mode.
How to disengage the automatic locking mode
Disconnect the combination lap/shoulder belt and allow it to retract
completely to disengage the automatic locking mode and activate the
vehicle sensitive (emergency) locking mode.
After any vehicle collision, the safety belt systems at all outboard
seating positions (except the driver position, which does not
have this feature) must be checked by an authorized dealer to verify
that the automatic locking retractor feature for child seats is still
functioning properly. In addition, all safety belts should be checked for
proper function.
BELT AND RETRACTOR ASSEMBLY MUST BE REPLACED if
the safety belt assembly "automatic locking retractor" feature or
any other safety belt function is not operating properly when checked
by an authorized dealer. Failure to replace the Belt and Retractor
assembly could increase the risk of injury in collisions.
Safety belt pretensioner
Your vehicle is equipped with safety belt buckle pretensioners at the
driver and front outboard passenger seating positions.
Do NOT place objects between the seats, as this could interfere
with the functioning of the pretensioner.
The driver and front outboard passenger safety belt pretensioners are
designed to activate only during certain frontal or near-frontal collisions
