GENERAL DESCRIPTION AND SYSTEM OPERATION
BUMPERS
The bumper systems are designed to sustain a collision into a fixed barrier at either 8 km/h (5 mph) or 4 km/h (2.5 mph) without damage. After absorbing the energy of a col-

lision, the bumper systems restore themselves to their original positions. The bumpers feature an internal foam energy absorber and a polymer fascia cover.
