9O – 2 BUMPERS AND FASCIAS
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
BUMPERS
The bumper systems are installed with the body color
bumper and the general bumper according to the vehicle
grade.
The bumper systems are designed to sustain a collision
into a fixed barrier at 4 km/h (2.5 mph) without damage.
After absorbing the energy of a collision, these bumpersystems restore themselves to their original position.
Both the front and the rear bumpers feature an internal
foam energy absorber and a polymer fascia cover. The
front bumper consists of the bumper fascia and the im-
pact bar. Remove the fascia before removing the impact
bar. The rear bumper consists of the bumper fascia and
the bracket. Removal of rear bumper brackets can be
possible without removing the bumper fascia.
