The Nissan Titan XD has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection.

The Titan XD has standard Rear Automatic Braking that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The Sierra HD doesn’t offer backup collision prevention brakes.
