Hi,

I was just trying this out today.

The 1st Low range centre light comes on okay.
The 2nd Centre diff lock comes on okay.
The 3rd Rear diff lock does not illuminate when I move the lever for a third time.

It says in the book that Rear diff only engages while engine is running, and I have done this, does the car need to be moving, or am I missing something?

Thanks

 

Unless your Cayenne has the "Advanced Off Road Technology Package" (very few do), you don't actually have a rear diff lock. All the Cayennes have the indicator light; it just doesn't illuminate on cars that don't actually have the locking rear diff.

 

Oh!, thanks!, wish the book stated that!

Happy New Year!

 

It does:

Interesting, my book does not have this statement.
