The Mirai has standard Whiplash Injury Lessening Seats (WIL), which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the WIL system moves the headrests forward to prevent neck and spine injuries. The Air doesn’t offer a whiplash protection system.
The Mirai has standard Safety Connect™, which uses a global positioning satellite (GPS) receiver and a cellular system to help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Air doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the Mirai and the Air have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, around view monitors, rear cross-path warning and driver alert monitors.
