If the windows are left open on the Expedition Max the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can also lower the windows the same way. The driver of the Suburban can only operate the windows from inside the vehicle, with the ignition on.
In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Expedition Max’s exterior PIN entry system. The Suburban doesn’t offer an exterior PIN entry system, and its OnStar® can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.
The Expedition Max (except XLT)’s optional Enhanced Active Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Suburban doesn’t offer an automated parking system.
