When to use the automatic locking mode
This mode should be used any time a child safety seat, except a
booster, is installed in passenger front or rear seating positions. Children
12 years old and under should be properly restrained in a rear seating
position whenever possible. Refer to Safety restraints for children or
Safety seats for children later in this chapter.
How to use the automatic locking mode
1. Buckle the combination lap and
shoulder belt.
2. Grasp the shoulder portion and
pull downward until the entire belt
is pulled out.
• 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.
WARNING: After any vehicle collision, the safety belt system at
all passenger seating positions 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.
WARNING: 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.
