| Side crash test ratings can be compared across vehicle categories.

This rating applies to vehicles other than the specific model and body style tested.
The Chevrolet TrailBlazer was introduced in the 2002 model year, and the GMC Envoy was redesigned the same year. The Buick Rainier and Isuzu Ascender (5-passenger) were introduced in the 2004 model year.
Beginning with 2005 models, front and rear side head curtain airbags became available as options. The Saab 9-7X was introduced late in the 2005 model year with standard head curtain airbags. The Buick Rainier was discontinued after the 2007 model year. Beginning with the 2008 model year, side airbags were made standard on all remaining models.
Injury measures
Driver — Measures taken from the dummy indicate that rib fractures and/or internal organ injuries would be likely in a crash of this severity. Serious neck injuries would also be possible.
Passenger — Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.
Head protection
Driver — The dummy's head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof.
Passenger — The dummy's head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof.
