Nissan Navara has improved its Euro Ncap adult occupation protection rating to three stars, following a modification to the pickup truck's airbag control unit software.

The vehicle achieved a maximum score in the side impact test, and for its protection of a three-year-old. In pedestrian protection, the vehicle scored two out of four stars.

Previous results saw the Navara's rating in adult occupant protection affected by the delay in the front airbags deploying.

Following the first test, Nissan developed a modification the software which controls the airbags to correct the problem which was limited to model year 2008 Navaras built between May and December 2007.
