If the 4-matic light comes on and then goes off when the engine is started then the 4-matic system should be functional. Test it by finding a gravel patch and spinning the rear wheels taking off. It should illuminate the triangle warning in the speedo and immediately lock the t-case and pull off without further spinning. Under the hood check the fluid level in the hydraulic reservoir on the drivers fender. It should be at least 2/3s full, pull the dipstick and check its level.

Check the SLS by sitting on the rear with a (portly) friend while idling. You should feel it slowly pump up as it levels out your weight.

Also check that the rear hatch holds itself up. The struts are buried and a real PITA to replace. Additionally check the function of the rear wiper motor. A sluggish motor is cause for concern as they aren't cheap or easy to replace. Check that the rear washer works as well. They break the hose in the right tailgate hinge and that isn't an easy fix either. Lastly make sure the tailgate power latches. You don't slam them, just set the tailgate down on the latch and it should pull down and latch automaticly.

If it has the factory sound system.... they tend to crap out due to water leaking in around the antenna seal. Open the cover in the right rear and inspect the audio components in that vicinity for corrosion or water ingress damage.
