E39 Rear Head Protection System (HPS)
For 2001, rear head protection airbags (HPS)
will be available for sedans ordered with rear
side airbags.
The airbags are a cushion (not an ITS) that is
deployed from the C-pillar. The HPS will n no
ot
t
be
de-activated along with the side airbags from
the factory since there is no danger to small
children sitting out of position.
A vehicle with rear HPS can be identified by
observing “HPS” embossed in the C-pillar
cover.
Rear airbags with HPS will be standard equipment on the 2001 E39 M5.
