Combination lap and shoulder belts
Before fastening the safety belt,
make sure the shoulder belt passes
through the belt holder on the top
of the seatback.
1. Insert the belt tongue into the
proper buckle (the buckle closest to
the direction the tongue is coming
from) until you hear a snap and feel
it latch. Make sure the tongue is
securely fastened in the buckle.
2. To unfasten, push the release
button and remove the tongue from
the buckle.
