A vehicle starting system for activating an ignition of a vehicle. The system includes a remote transmitting device operable to communicate a start signal in response to a user input, and a control at a vehicle that receives the start signal. The control processes images captured by at least one imaging device to determine if the images are indicative of the vehicle being parked in an enclosed environment. The control activates an ignition of the vehicle in response to the start signal and the image processing.
