If you plan to own a 2011 General Motors Co. vehicle, then chances are that you'll be delighted with a feature that enables you to use a smartphone to start your vehicle remotely, activate the horn and lights, and remotely lock and unlock your doors.
These functions are typically found on a key fob but with the mobile applications that were developed with OnStar, owners of new Chevrolet, Cadillac, Buick and GMC models can use Apple's iPhone and phones using Google's Android operating system to control their vehicles.
The use of a mobile phone indicates that these features can be controlled no matter what the distance is between the driver from the vehicle.
For example, if you forget to lock your car and you're already at the airport terminal, you can easily send a locking signal.
OnStar subscribers will also be able to get diagnostic information on their phones, such as the fuel-tank level, remaining oil life, recommended tire pressure and average mile per gallon driven.
Last January, OnStar revealed a smartphone application for Chevrolet Volt owners that will allow them to manage charging and perform other functions remotely.
