Standard safety features include anti-lock disc brakes, stability control, and a full complement of airbags with dual-stage frontal and thorax side-impact, driver and front passenger, and protection for head curtain side-impact at both front and rear outboard seating positions.
After all those good points, there's one noteworthy flaw worth pointing out: rearward visibility can be downright horrible for some drivers, and rear-seat headrests don't remove or fold down to open up vision in the rear-view mirror. Optional rear parking sensors round out the available safety gear, combining with the standard rearview camera to make it easier to see obstacles behind the vehicle. The display is mounted in the rearview mirror in non-navigation-equipped vehicles. All GMC Terrains come standard with a PASS-Key III Theft Deterrent System as well.
