For enhanced safety, the front and second-row seat shoulder belts of the Hyundai Santa Fe Hybrid have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Volkswagen Tiguan doesn’t offer pretensioners for its second-row seat belts.
Both the Santa Fe Hybrid and Tiguan have child safety locks to prevent children from opening the rear doors. The Santa Fe Hybrid has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Tiguan’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Santa Fe Hybrid are reminded to check the back seat when a sensor determines the back seat is occupied. The Tiguan doesn’t offer a back seat reminder.
The Hyundai Santa Fe Hybrid has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Tiguan doesn’t offer knee airbags.
The Santa Fe Hybrid’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Tiguan doesn’t offer a driver alert monitor.
Both the Santa Fe Hybrid and the Tiguan have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive and around view monitors.
The Hyundai Santa Fe Hybrid weighs 491 to 843 pounds more than the Volkswagen Tiguan. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
