Lincoln 1999 Town Car - Manual (Page 85)

All occupants of the vehicle, including the driver, should always
properly wear their safety belts, even when an air bag SRS is
provided.
It is extremely dangerous to ride in a cargo area, inside or
outside of a vehicle. In a collision, people riding in these areas
are more likely to be seriously injured or killed. Do not allow people to
ride in any area of your vehicle that is not equipped with seats and
safety belts. Be sure everyone in your vehicle is in a seat and using a
safety belt properly.
Each seating position in your vehicle has a specific safety belt
assembly which is made up of one buckle and one tongue that
are designed to be used as a pair. 1) Use the shoulder belt on the
outside shoulder only. Never wear the shoulder belt under the arm. 2)
Never swing the safety belt around your neck over the inside shoulder.
3) Never use a single belt for more than one person.
Combination lap and shoulder belts
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.
