Every Altima features dual SRS front air bags as standard equipment. These protect the driver and front passenger in the event of a frontal collision.

Air bags mounted on the outboard sides of the front seatbacks deploy immediately when air bag sensors detect that a significant side impact is occurring,

3-point (lap and shoulder) seat belts are the primary restraint system in any vehicle, helping reduce the occupants' likelihood of contact with interior components or ejection from the vehicle in the event of a crash.

Sensors in each front seat belt detect whether the seat belt is in use by an occupant. Seat belt use, other air bag system sensors, and the severity of the impact determine whether the air bag will inflate.

When a driver suddenly brakes very hard, the pre-crash system tightens the front seat belts - then releases this tension if braking stops and no impact occurs.

Double pretensioners and load limiters work with other components of the restraint system to help protect passengers in certain frontal impacts.

Altima's active head restraints provide additional protection against serious injury from the effects of whiplash for front seat passengers.

Zone Body construction optimizes the vehicle's structural design and material selection, incorporating front and rear crushable zones and a reinforced occupant zone to help protect occupants in the event of a crash.

Column design helps absorb crash energy by compressing during certain frontal impacts, which helps reduce the risk of injury.

Front and rear crumple zones absorb impact energy, helping to reduce the risk of injury to passengers by helping to maintain passenger compartment structural integrity.

Placement helps protect occupants in the event of certain side impacts.
