The Metris Passenger doesn’t offer a whiplash protection system.
The Odyssey EX/EX-L/Touring/Elite has standard Collision Mitigation Braking System, 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 Metris Passenger offers an available collision warning system without the automated brake feature that would prevent or reduce the collision if the driver fails to react.
To help make backing safer, the Odyssey EX/EX-L/Touring/Elite’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 Metris Passenger doesn’t offer a cross-path warning system.
The Odyssey EX/EX-L/Touring/Elite has standard HondaLink Assist, which uses a global positioning satellite (GPS) receiver and a cellular system to send emergency personnel to the scene if any airbags deploy.
