The passenger compartment of the Tarraco remained stable in the frontal offset test.  Dummy readings indicated good protection of the knees and femurs of the driver and passenger.  SEAT showed that a similar level of protection would be provided to occupants of different sizes and to those sitting in different positions.  In the full-width rigid barrier test, protection of the driver was good for all critical body areas.  For the rear dummy, protection was goof or adequate for all critical parts of the body. In both the side barrier test and the side pole impact, protection of all critical body areas was good and the Tarraco scored maximum points.  Tests on the front seats and head restraints demonstrated good protection against whiplash injury in the event of a rear-end collision.  A geometric assessment of the rear seats indicated marginal whiplash protection.  The standard-fit autonomous emergency braking (AEB) system performed well in tests at the low speeds, typical of city driving, at which many whiplash injuries are caused.

In the frontal offset test, protection of all critical body areas was good or adequate for both the 6 year and 10 year dummies. In the side barrier test, protection of both child dummies was good and maximum points were scored. The front passenger airbag can be disabled to allow a rearward-facing child restraint to be used in this seating position. Clear information is provided to the driver regarding the status of the airbag and the system was rewarded. All of the restraint types for which the Tarraco is designed could be properly installed and accommodated in the front passenger seat and the second row. However, the optional third row seats were too small to accommodate universal child restraints properly.

The protection provided by the bonnet to the head of a struck pedestrian was good or adequate over most of its surface, with areas of good and poor performance. Protection of pedestrian's legs and of the pelvis area was good in all test areas and the Tarraco scored maximum points. The AEB system can detect pedestrians and cyclists, as well as other vehicles. The system performed well when tested for its reaction to vulnerable road users such as these.

The AEB system gave generally good results in tests of its functionality at highway speeds. The car has a lane assistance system which helps prevent inadvertent drifting out of lane but can also intervene in some more critical situations. A driver-seat speed assistance system allows the limiter to be manually set to the appropriate speed. A seatbelt reminder is standard for front and rear seats.
