Right Front Passenger Position
To learn how to wear the right front passenger's safety
belt properly, see Driver Position on page 1-15.
The right front passenger's safety belt works the same
way as the driver's safety belt — except for the following.
If you ever pull the shoulder portion of the belt out all
the way, you will engage the child restraint locking
feature. If this happens, just let the belt go back all the
way and start again.
If the belt stops before it reaches the buckle, tilt the
latch plate and keep pulling until you can buckle the belt.

Rear Seat Passengers
It is very important for rear seat passengers to buckle
up! Accident statistics show that unbelted people in
the rear seat are hurt more often in crashes than those
who are wearing safety belts.
Rear passengers who are not safety belted can be
thrown out of the vehicle in a crash. And they can strike
others in the vehicle who are wearing safety belts.
Lap-Shoulder Belt
All rear seating positions have lap-shoulder belts.
Here is how to wear one properly.
