When inspecting a vehicle that has been involved in a collision, be sure to check all of the seat belt systems regardless of whether or not the system was activated in the collision. Replace any damaged or malfunctioning systems.

ROAD TEST (IN SAFE AREA)

CAUTION:

Conduct this test in a safe area.

(a) Fasten the front seat belts.

(b) Drive the Toyota Prius vehicle at 16 km/h (10 mph) and firmly depress the brake pedal. Check that the front seat outer belt assemblies lock and cannot be extended.

If a front seat outer belt assembly does not lock, replace it.
