For a relatively small vehicle, the 2009 Scion xD earns respectable scores in front impact crash tests and excellent scores in side impact tests.
In National Highway Traffic Safety Administration (NHTSA) crash testing, the xD scored four of five stars for both driver and passenger side frontal impact, and the same rating for rollover resistance. The vehicle earned five stars for both side impact ratings, driver and rear passenger. The Insurance Institute for Highway Safety (IIHS) awarded the 2008 xD an "acceptable" rating for its crash offset test and a "good" for both side and rear impact. At the time of this writing, it has not tested the 2009 model, but since there have been no structural changes, the 2008 test is representative.
Unlike some cars costing thousands more, the 2009 Scion xD boasts a long list of standard safety features. Edmunds calls the xD's roster of standard safety features "impressive." This includes anti-lock brakes with brake assist, traction control, front seat side airbags, full-length side curtain airbags, and front active head restraints, which Kelley Blue Book notes "push the occupants back into their seats in the event of an accident." Also standard is a tire pressure monitoring system. Not standard (but available together as an option) are traction control and an electronic stability system, according to Cars.com, who also point out the brakes "use a disc/drum setup, not the stronger four-wheel-disc type." Visibility is "bad to the rear corners due to thick roof pillars but is OK otherwise," declares ConsumerGuide.
