The passenger compartment of the T-Cross remained stable in the frontal offset test. Dummy readings indicated good protection of the knees and femurs of the driver and passenger. VW 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 dummy was good for all critical body areas and was at least adequate for the rear passenger. In both the side barrier and the more severe side pole impacts, protection of all critical body regions was good and the T-Cross scored maximum points in both tests. 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 also indicated good whiplash protection. The standard-fit 'Front Assist' autonomous emergency braking (AEB) system performed well in tests of its functionality at the low speeds, typical of city driving, at which many whiplash injuries occur.

In the frontal offset test, readings of neck tension in the 10 year dummy indicated marginal protection for that part of the body. Otherwise, protection was good or adequate for the 6 and 10 year dummies. In the side barrier test, protection of both dummies was good, for all critical parts of the body. The front passenger airbag can be disabled to allow a rearward-facing airbag 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. All of the restraints for which the T-Cross is designed could be properly installed and accommodated in the car.

The protection provided to the head of a struck pedestrian was predominantly good or adequate over the bonnet surface. Good protection was provided to pedestrians' legs but protection of the pelvis was mixed. The T-Cross has an AEB system which can detect vulnerable road users, as well as other vehicles. Good results were seen in tests of the system's performance when detecting pedestrians and cyclists, with collisions avoided or mitigated in most scenarios.

The T-Cross has a seatbelt reminder for the front and rear seats, as standard. The AEB system performed well in tests of its reaction to other vehicles at highway speeds. A driver-set speed limiter is standard equipment, as is a lane support system which helps to prevent inadvertent drifting out of lane, and also intervenes in some more critical situations.
