(January 6, 2010) LAS VEGAS — Chevrolet and OnStar unveiled the auto industry’s first working smartphone application that will allow Chevrolet Volt owners 24/7 connection and control of vehicle functions and OnStar features remotely.

OnStar’s Mobile Application allows drivers to communicate with their Volt from Droid by Motorola, Apple iPhone and Blackberry Storm smartphones. It uses a real-time data connection to perform tasks from setting the charge time to unlocking the doors.

The Chevrolet Volt OnStar smartphone application is designed to enhance the overall Volt ownership experience with interaction and control never offered before on any electric vehicle. The application:

    * displays charge status – plugged in or not, and voltage (120V or 240V)
    * provides flexibility to “Charge Now” or schedule charge timing
    * displays percentage of battery charge level, electric and total ranges
    * allows owner to manually set grid-friendly charge mode for off-peak times when electricity rates are lowest
    * sends text or email notifications for charge reminders, interruptions and full charge
    * displays miles per gallon, electric only miles, and odometer readings
    * shows miles per gallon, EV miles and miles driven for last trip and lifetime
    * remotely start the vehicle to pre-condition the interior temperature

“The Chevrolet Volt ushers in a new era of automotive technology and calls for a new level of connectivity and control,” said Walt Dorfstatter, president, OnStar. “Nearly 6 million vehicles on the road today use OnStar to stay connected, and our new smartphone app will make that even easier for Volt drivers.”

OnStar’s real-time data connection also helps drivers maximize the environmental benefits of owning a Volt, even when not in the vehicle. The application’s intuitive Charge Status feature simplifies setting the charge time. Rather than using battery power, the application allows owners to start the Volt remotely to pre-condition the interior temperature using power from the grid. This preserves the battery charge for driving without gasoline.

When a charge command is activated, the Volt owner will receive a confirmation message on the application alerting the owner that a command has been successfully sent to the vehicle. If in view of the Volt, a green LED charge light on the dash will indicate the charge state.

Traditional OnStar features such as door lock, unlock and remote horn and lights – which have typically been accessible only through a call into the OnStar call center – will now be available via the application.
