The XC40’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The CX-30 doesn’t offer pre-crash pretensioners.
Both the XC40 and CX-30 have child safety locks to prevent children from opening the rear doors. The XC40 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-30’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 XC40 has standard Post-impact braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The CX-30 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
When descending a steep, off-road slope, the XC40’s standard Hill Descent Control allows you to creep down safely. The CX-30 doesn’t offer Hill Descent Control.
To help make backing out of a parking space safer, the XC40 has standard Cross Traffic Alert with Braking Intervention, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. Only the CX-30 Turbo Premium Plus offers Smart Braking Support - Rear Crossing.
Both the XC40 and the CX-30 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, 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, driver alert monitors and available around view monitors.
