Thread: D4 - low cranking battery warning after nights camping?

When I start going away a few days at a time I might wire in a switch in series to the passenger door so the thing is always open. Not the sort of thing you'll be able to forget when you leave. The dash will remind you and the door won't lock

Don’t believe it, be wary crawling under it with a door open.
It CAN and WILL settle if it sees a change in any corner or end.

Never, ever crawl under an EAS car without a fail safe to prevent the body lowering onto you. I raise the D4 to the highest LLAMS setting (gives you heaps of clearance) and place stands at about each of the four jacking points if I need to get under the car without taking a wheel off.
You don't want something like the famous Windows blue screen of death causing the car to drop on top of you!
The first time I experienced the EAS going into extended mode (in a P38) was when I was temporarily stuck crossing a washed out gully on a farm. The fact that the car first lowered to the bump stops (or thereabouts) before rising into extended mode was a light bulb moment for me in the sense that I realised it wouldn't take much of a glitch for that to happen in the workshop when you were happily camped under it.

That’s my SWMS too.
Full lift and stands at suitable points to stop it dropping.

Straight from the workshop manual:
______________________
Door Open
The air suspension control module will stop all height change requests while any of the doors are open. Vehicle leveling continues with a door open by keeping the vehicle at the height when the door was opened if the vehicle load changes. Door open status is ignored when the vehicle speed is above 8 km/h (5 mph).
______________________
In practice, suspension changes are inhibited when you open a door (I don't think this applies to the tailgate) unless you remove or add a load heavy enough to raise or lower a corner, then the car corrects the height. It's pretty marginal, though, you just hear a few clicks and the car wobbles a bit and you do wonder why it bothered to do that, but it's a neat party trick.

That can only happen if the engine is running, if the engine is off,the vehicle can only go down.So in some situations,it can't be kept at the same height,with engine off.It will try to level,but go down,so won't be 'at the height when door was opened',as per the manual.Put a load in the rear,as an example,engine off,it will go down, relevelling.

They also seem to relevell pretty quickly after stopping,engine off and people have exited the vehicle.

Maybe something is wrong with ours,but numerous times we notice it relevels right down,in say 2 to 3 days in one place,sleeping in RTT,all doors shut
Open a door,first click,and it doesn't seem to happen,or it could slightly,but not much at all.

Sure getting under a vehicle with EAS,for whatever reason, is very dangerous,thats common sense(for most).

That is not correct - it can level up if there is enough air pressure in the tank. On flat ground try jacking the back up on one side a small amount - with a full air tank the car will rise to match the raised corner.

The whole thing about not adjusting height with the door open is about height changes originating from the console switch - eg onroad to off road, etc.

Self leveling is different and can occur not matter if the engine is on or off - the vehicle does not level with respect to the horizontal but to the ground - ie it levels so height input from the height sensors are the same.

My drive is at an angle of 15degrees - my car does not auto level so the car is horizontal eg 15 degrees nose high - but levels so all sensors are the same so the car height from the ground is equidistant all round.

I have to agree..drove the car into the paddock to connect the trailer..lowered the car to access height backed under the coupling.. ...turned the car off...walked to the back and 3 of us watched as the car moments later dropped a little more at the back.. then settled. We all wondered why'd it do that😞. My daughter said that car is possessed😃

Instead of leaving doors or tailgate open, why not just leave the windows down?
