Both the Nautilus and Rav4 Hybrid have child safety locks to prevent children from opening the rear doors. The Nautilus 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 Rav4 Hybrid’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 Nautilus are reminded to check the back seat. The Rav4 Hybrid doesn’t offer a back seat reminder.
The Lincoln Nautilus 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 Rav4 Hybrid doesn’t offer a front passenger side knee airbag.
The Nautilus 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. A system to reveal vehicles in the Rav4 Hybrid’s blind spot costs extra.
To help make backing out of a parking space safer, the Nautilus has standard Cross-Traffic Alert and Rear Cross Traffic Braking automatically engages the brakes to help avoid a collision. Toyota charges extra for Rear Cross Traffic Alert on the Rav4 Hybrid.
Both the Nautilus and the Rav4 Hybrid have standard driver and passenger frontal airbags, front side-impact airbags, driver 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, rearview cameras, driver alert monitors and available all wheel drive.
The Lincoln Nautilus weighs 544 to 807 pounds more than the Toyota Rav4 Hybrid. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
