The Metris Passenger has standard child safety locks to prevent children from opening the rear doors. The NV Passenger doesn’t offer child safety locks.
The Metris Passenger offers optional Active Brake Assist, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The NV Passenger doesn't offer collision warning or crash mitigation brakes.
The Metris Passenger’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The NV Passenger doesn’t offer a lane departure warning system.
The Metris Passenger’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 NV Passenger doesn’t offer a driver alert monitor.
For better protection of the passenger compartment, the Metris Passenger uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The NV Passenger uses a body-on-frame design, which has no frame members above the floor of the vehicle.
The Metris Passenger has standard Mercedes-Benz Emergency Call, which uses a global positioning satellite (GPS) receiver and a cellular system to send emergency personnel to the scene if any airbags deploy. The NV Passenger 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 Metris Passenger and the NV Passenger have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available blind spot warning systems and rear parking sensors.
