2011 Toyota Prius II

Convenience

• Cruise control maintains a preset vehicle speed; automatically increasing or decreasing throttle to maintain that speed.
• A proximity key with keyless entry and push button start allows the driver to unlock the vehicle by approaching it and/or touching the door handle. A keyfob or keycard carried by the driver identifies the person to the vehicle. The driver is then able to start the engine by twisting the ignition switch, pressing a button, or touching a select portion of the vehicle's interior.

Powertrain and Mechanical

• Variable valve control allows the lift, duration and/or timing of the intake or exhaust valves to be altered while the engine is in operation.

Safety and Security

• Brake assist senses panic braking from the speed of the brake pedal's travel and applies all available power brake boost.
• Ignition immobilizer is a passive means of security. It consists of a transmitter embedded within the ignition key and a sensor located in the vehicle. These two circuits must be present, and must recognize each other before the vehicle will start.
• When starting from an incline position, the vehicle automatically applies brake force to prevent itself from rolling back.
• Typically on hybrid, plug-in hybrid, or full-electric vehicles, it is an external sound designed to alert pedestrians of the vehicle.

Technology and Telematics

• Otherwise known as Bluetooth, this technology allows electronic devices to integrate with the vehicle systems without the need for a physical connection between them.
