1-20 Seats and Restraint System
Lap-Shoulder Belt
All seating positions in the vehicle
have a lap-shoulder belt.
If you are using a rear seating
position with a detachable safety belt
and the safety belt is not attached,
see Third Row Seats on page 1-10
for instruction on reconnecting the
safety belt to the mini-buckle.
The following instructions explain
how to wear a lap-shoulder belt
properly.
1. Adjust the seat, if the seat is
adjustable, so you can sit up
straight. To see how, see "Seats"
in the Index.
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.
If this happens, let the belt go
back all the way and start again.
3. Push the latch plate into the
buckle until it clicks.
