Had a 17 Expedition rental for 10 days last Mo. Rode like a bouncy house until put in 4wd hi. Someone likely blew the struts on the way from WA to CA as the plates indicated. Is it just me or does the AWD soak up some of the terrain? If it does I’m a AWD junkie.

It looks like a four wheel drive

My AWD Tahoe suits me fine in PA, the system has three open diffs with no way to lock. It relies on the brakes to be applied on any wheel spinning faster than the others. I'm starting to have some issues with the encoder motor and the inertia sensor now, at its age and miles 180K. The AWD system on mine has always been noisy. I've had both front and rear diffs rebuilt, the noise must be the transfer case.

Does putting it into 4 lo lock the center differential in the transfer case?

Looks to me like AWD with a 2 speed transfer case. That top button is traction control on/off. If you push it, do you get a message or light about the stability system being off?
IF YOU REALLY WANT TO KNOW WHAT YOU GOT (everything, its got):
Here are two GM RPO CODE MASTER LISTS,
https://www.silveradosierra.com/resources/file/3817
https://www.marshu.com/images-websi...codes/gm-firebird-camaro-GM-RPO-car-codes.pdf
You might have got the build sheet included with your vehicle, but probably not. There are several ways to contact GM to have them send you a copy so you know what every option is... Otherwise all your RPO codes (the individual codes that tell every option your vehicle has) is listed in your glovebox.

From a quick scan it looks like suspension and driveline are F** and G** Codes. Transmission is an M** code, not sure if that might be your transfer case to answer it.

During business hours select: question about a vehicle I already own. Give them your VIN and ask for the RPO build sheet.
