Lap/Shoulder Belt
PART 5: SEAT AND RESTRAINT SYSTEMS
Lap/Shoulder Belt
02998
Person In Crash, Unbelted
The combination lap-shoulder belt is equipped with a locking
mechanism. The system adjusts automatically to a person’s
size and movements as long as the pull on the belt
is slow. Hard braking or a collision locks the belt. The belt
will also lock when driving up or down a steep hill or in a
sharp curve. To fasten the belt,
1. Grasp the belt tongue and pull the belt in a continuous
slow motion across your chest and lap.
2. Insert the belt tongue into the buckle on the inboard
side of the seat.
3. Push down until the tongue locks securely (with an audible
click). Pull on the belt to check for proper fastening.
• Pull the shoulder section to make sure the belt fits
snugly across the chest.
• The shoulder belt must be positioned over the
shoulder— it must never rest against the neck.
• Belts should fit snugly across the pelvis and chest.
Make sure any slack is wound up on the retractor.
To unfasten the belt:
1. Push in the release button on the buckle. The belt will
spring out of the buckle.
