The CX-9 Touring/Grand Touring/Signature has standard Smart Brake Support, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn't react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Sequoia doesn't offer collision warning or crash mitigation brakes.
Full-time four-wheel drive is optional on the CX-9. Full-time four-wheel drive gives added traction for safety in all conditions, not just off-road, like the only system available on the Sequoia.
The CX-9 Grand Touring/Signature's lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The Sequoia doesn't offer a lane departure warning system.
To help make backing safer, the CX-9 Touring/Grand Touring/Signature's cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Sequoia doesn't offer a cross-path warning system.
For better protection of the passenger compartment, the CX-9 uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The Sequoia uses a body-on-frame design, which has no frame members above the floor of the vehicle.
The CX-9 has standard E911 Automatic Emergency Notification, which uses a global positioning satellite (GPS) receiver and a cellular system to send emergency personnel to the scene if any airbags deploy. The Sequoia doesn't offer a GPS response system, only a navigation computer with no live response for emergencies, so if you're involved in an accident and you're incapacitated help may not come as quickly.
Both the CX-9 and the Sequoia have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, available blind spot warning systems and rear parking sensors.
