The passenger compartment of the Ka+ remained stable in the frontal offset test.  Dummy readings showed good protection of the knees and femurs of both the driver and passenger.  However, structures in the dashboard were thought likely to pose a risk to occupants of different sizes and to those sat in different positions and the score was penalised.  Dummy readings of chest compression indicated a marginal level of protection for this part of the body for both the driver and passenger.  In the full-width rigid barrier test, protection of the driver was good for all areas apart from the chest, protection of which was adequate.  However, measurement of compression indicated poor protection for the chest of the rear passenger dummy and head decelerations demonstrated weak head protection.  In contrast, the Ka+ scored maximum points in both the side barrier test and the more severe side pole impact, with good protection of all critical body areas.  Tests on the front seats and head restraints demonstrated good protection against whiplash injuries in the event of a rear-end collision.  A geometric assessment of the rear seats indicated a marginal level of whiplash protection.  The Ka+ does not have an autonomous emergency braking system.

In the frontal offset test, readings from the 6 year dummy indicated good head protection, marginal chest protection and a weak level of protection for the neck.  The 10 year dummy also showed weak protection of the neck.  Dummy readings indicated good protection of the chest and head but the score was penalised owing to the diagonal part of the seatbelt slipping off the dummy's shoulder in the test.  In the side barrier test, protection of all critical body areas was good and the Ka+ scored maximum points.  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 to the driver regarding the status of the airbag and the system was rewarded.  Child restraints could not be properly installed in the rear centre seating position and the iSize anchorages could not be easily engaged for one restraint in the rear outboard seats.

The bonnet provided predominantly good or adequate protection to the head of a struck pedestrian, with poor results recorded on the front edge of the windscreen and on the stiff windscreen pillars.  The bumper scored maximum points for its protection of pedestrians' legs with good results at all test points.  Protection of the pelvis was mixed, with good and poor results.

The Ka+ has a seatbelt reminder system for the front seats only, and a standard-fit driver-set speed limitation device.  Neither autonomous emergency braking nor lane assistance is available.
