For enhanced safety, the front and rear seat shoulder belts of the Nissan Leaf 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 Toyota Prius Prime doesn’t offer pretensioners for its rear seat belts.
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 Leaf are reminded to check the back seat if they opened the rear door before starting out. The Prius Prime doesn’t offer a back seat reminder.
The Nissan Leaf has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps 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 Prius Prime doesn’t offer a front passenger side knee airbag.
The Leaf SV PLUS has a standard Around View® Monitor to allow the driver to see objects all around the vehicle on a screen. The Prius Prime only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
The Leaf has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. Only the Prius Prime Limited offers a blind spot warning system.
To help make backing out of a parking space safer, the Leaf has standard Rear Cross Traffic Alert, helping the driver avoid collisions. Only the Prius Prime Limited offers Rear Cross Traffic Alert.
Both the Leaf and the Prius Prime have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee 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, lane departure warning systems, rearview cameras, available daytime running lights and driver alert monitors.
