The passenger compartment of the Swift remained stable in the frontal offset test.  Dummy readings indicated good protection of the knees and femurs for both the driver and passenger.  Suzuki showed that a similar level of protection would be provided to occupants of different sizes and to those sat in different positions.  In the full-width rigid barrier test, protection of the chest was marginal, both for the driver and the rear seat passenger.  Otherwise, protection of critical body areas was rated a good or adequate.  The Swift scored maximum points in both the side barrier test and the more severe side pole impact, with good protection of all critical body regions.  Tests on the front seats and head restraints demonstrated good protection against whiplash injuries in the event of a rear-end collision.  However, a geometric assessment of the rear seats indicated poor whiplash protection for occupants in those seating positions.  The Swift has, as part of its 'Radar Brake Support' option pack, autonomous emergency braking.  The system works at the low speeds, typical of city driving, at which many whiplash injuries are caused and, in tests of this functionality, the system performed adequately.

In the frontal offset test, readings from the 6 year dummy indicated poor chest protection and weak protection of the neck.  For the 10 year dummy, neck protection was marginal.  In the side barrier test, decelerations in the chest indicated poor protection of the 10 year dummy.  Protection in this test was, otherwise, good.  The front passenger airbag can be disabled to allow a rearward-facing child restraint to be used in that seating position.  Clear information is provided regarding the status of the airbag and the system was rewarded.  All of the restraint types for the which the Swift is designed could be properly installed and accommodated.

The protection provided by the bonnet to the head of a struck pedestrian was predominantly good or adequate, with poor results recorded on the stiff windscreen pillars.  The bumper scored maximum points, offering good protection to pedestrians' legs at all test locations.  Protection of the pelvis was predominantly good but some weak and poor results were also recorded.

The Swift has, as standard, as seatbelt reminder system for the front and rear seats.  Autonomous emergency braking is included in the 'Radar Brake Support' option pack.  Tests of its functionality at highway speeds showed good performance.  A driver-set speed limiter is available as an option, separate from the pack.
