The 2008 Cadillac DTS scores well in front impact crash tests, but less so in side impact tests.
The National Highway Traffic Safety Administration (NHTSA) gives the DTS five stars for driver-side front impact protection; all other front and side impact tests, as well as rollover tests, are rated at four stars. The Insurance Institute for Highway Safety (IIHS), meanwhile, gives the DTS a “good” rating for its more stringent front-impact test, but only an “acceptable” rating for side impacts.
There are plenty of standard safety features on the 2008 Cadillac DTS as outlined by Cars.com. Anti-lock brakes and "StabiliTrak electronic stability system with brake assist" are among them, as are six airbags (side impact, curtain, and front passenger unit). This includes the "new dual-depth" front airbags that deploy "either shallow or deep depending on crash severity, seat belt usage and occupant position," according to Cadillac.
Impressive as the standard 2008 Cadillac DTS trim is, some of the optional safety features are more interesting. For instance, Edmunds is impressed by the 2008 Cadillac rear bumper sonar system that uses radio waves to detect objects while in reverse. There are also Lane Departure Warning and Side Blind Zone Alert systems. These options are designed to alert Cadillac 2008 DTS drivers to the state of traffic around them with a series of alarms.
For an extra $2,000, the Cadillac DTS may be equipped with a night-vision option installed to project "onto the lower section of the windshield using a 'heads-up' display"; Motor Trend considers it especially useful "in inclement weather, when visibility is sharply reduced."
