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 Sentra are reminded to check the back seat if they opened the rear door before starting out. The Jetta doesn’t offer a back seat reminder.
The Nissan Sentra has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Jetta doesn’t offer knee airbags.
Over 200 people are killed each year when backed over by motor vehicles. The Sentra (except S/SV) offers optional Rear Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Jetta doesn’t offer automatic braking for stationary objects directly to the rear.
The Sentra (except S/SV) offers an optional HD Around View® Monitor to allow the driver to see objects all around the vehicle on a screen. The Jetta only offers a rear monitor.
The Sentra’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 Jetta doesn’t offer a driver alert monitor.
Both the Sentra and the Jetta have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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 and rear cross-path warning.
