58 Seats and Restraints
2. Pick up the latch plate and pull the belt
across you. Do not let it get twisted.
The lap-shoulder belt may lock if you
pull the belt across you very quickly.
If this happens, let the belt go back
slightly to unlock it. Then pull the belt
across you more slowly.
If the shoulder portion of a passenger
belt is pulled out all the way, the child
restraint locking feature may be
engaged. See Child Restraint Systems
0 75. If this occurs, let the belt go back
all the way and start again. If the
locking feature stays engaged after
letting the belt go back to stowed
position on the seat, move the seat
rearward or recline the seat until the
shoulder belt retractor lock releases.
Engaging the child restraint locking
feature in the front outboard seating
position may affect the passenger
sensing system. See Passenger Sensing
System 0 67.
3. Push the latch plate into the buckle until
it clicks.
Pull up on the latch plate to make sure
it is secure.
If the belt is not long enough, see Seat
Belt Extender 0 60.
Position the release button on the buckle
so that the seat belt could be quickly
unbuckled if necessary.
4. If equipped with a shoulder belt height
adjuster, move it to the height that is
right for you. See Shoulder Belt Height
Adjuster in this section for instructions
on use and important safety information.
5. To make the lap part tight, pull up on
the shoulder belt.
