Main Message Centre Warnings - Axle

Hi. I've got a Freelander 2. Sometimes when on terrain where the camber and direction of travel changes suddenly and sharply I get a picture of an axle in the message centre. It disappears when the ground levels out. There's no reference to this is the handbook, I assume it means I've reached the end of the suspension travel? But can anyone help me with these messages? Is there a complete list anywhere? Thanks

You need to jack up the diesel filler cap, roll out the FL2 and roll an FL1 in place.

Then gently lower the filler cap back again...........

Think its telling you which way you have the steering turned.

Yes. Thanks. Stupid of me not to realise. Now worked out. Only appears when special programs on and steering wheel turned. Can't understand why not mentioned in handbook though.
