How long will the engine run after a remote start, and can I extend it?

The vehicle will automatically shut off after 15 minutes if left running after a remote start. You can extend the run time by an additional 15 minutes (for a total of 30 minutes) by repeating the remote start procedure while the engine is still running. A maximum of two remote starts or one remote start with one extension are allowed between ignition cycles. (Page 37)
