For enhanced safety, the front and second-row seat shoulder belts of the Toyota Highlander 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 Mazda CX-9 doesn’t offer pretensioners for its second-row 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 Highlander are reminded to check the back seat if they opened the rear door before starting out. The CX-9 doesn’t offer a back seat reminder.
The Toyota Highlander has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The CX-9 doesn’t offer knee airbags.
The Highlander has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The CX-9 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 Highlander AWD’s standard Downhill Assist Control allows you to creep down safely. The CX-9 doesn’t offer Downhill Assist Control.
Both the Highlander and CX-9 have Rear Cross Traffic Alert, but the Highlander Limited/Platinum has Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The CX-9’s Rear Cross Traffic Alert doesn’t automatically brake.
Compared to metal, the Highlander’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Mazda CX-9 has a metal gas tank.
Both the Highlander and the CX-9 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, 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, available all wheel drive and around view monitors.

The Toyota Highlander achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The CX-9 has not yet been fully evaluated by the IIHS for 2024.
