Both the Vistiq and CX-90 have child safety locks to prevent children from opening the rear doors. The Vistiq 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 CX-90’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.
The Vistiq has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The CX-90 doesn’t offer front seat center airbags.
A passive infrared night vision system standard on the Vistiq Premium Luxury/Platinum helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The CX-90 doesn’t offer a night vision system.
The Cadillac Vistiq’s rear backup camera has a standard washer for maintaining a clear view under various conditions. In contrast, the Mazda CX-90 does not offer a rear camera washer, meaning its effectiveness relies on manual cleaning by the user when necessary.
To help make backing out of a parking space safer, the Vistiq has standard Rear Cross Traffic Alert with Rear Cross Traffic Braking, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. Only the CX-90 Premium Plus/Turbo S offers Rear Cross Traffic Braking.
Both the Vistiq and the CX-90 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, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.
The Cadillac Vistiq weighs 1083 to 1480 pounds more than the Mazda CX-90. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
