Low Mode on 4 Wheel Air Suspension

Sometimes I like to have my truck on the low mode. But when it hits a certain speed it raises itself.

What's the reasoning behind this? Can you override it so you can drive in the low mode even at highway speed?

That's the way its supposed to work. Things you'll find in the owner's manual:

- Middle position is called Normal mode. This is your default ride height.
- Lower position is called Access mode. This is for ease of ingress/egress or loading the vehicle.
- Higher position is called Off-Road mode. This is used when you need more ground clearance.

All modes, except Normal, is temporary. Above a certain speed, around 20mph, it goes back to Normal mode.

In order to manually change modes, certain conditions need to be met:
- Engine must be on.
- Doors must be closed (except tailgate/liftgate).
- Vehicle must be below speed threshold.

Wow, I pretty much regurgitated what's in the manual. Please go read your manual. That's what I should have said instead!

As far as overriding things. Quick search will net you different options. Good luck!

I've read the manual. Perhaps you didn't really get my question.

I know how it works. I'm wondering why? Why does it default back to normal? Why can't I just drive around in the lower mode? At highway speeds I would think the low mode would would provide better handling...

Sorry, I misunderstood your question but ...

Because that's how BMW designed it. You'll have to ask BMW for a definitive answer but I suspect it has to do with compromised handling caused by less air pressure in the air struts/springs at the lower position.

Again, there are plenty of options to lower your X and/or overriding the default Normal mode.
