Emergency height doesn't activate

[DiscoSteve]

I remember when doing GOE course and we tried the emergency height selection, my car didn't do it. Not to take up time I just moved on but was worried it may be malfunctioning.
Wel yesterday I needed it for real and again it didn't work.
Anyone else had any problems and advice before I go and try my luck with land rover service department!?

Emergency height is only available if it has already gone into extended height. I suggest you need to try it in your driveway, by putting your D4 into offroad height - then place a jack/block of wood under the chassis rails. Then press the lower height button - the D4 will pick up it is grounded and raise itself to extended height. Once that has happened - then you can select emergency height.

My guess is you were not at extended height, so it wasn't selectable.

I tried it in my driveway when I was trying to wash underside - couldn't get it to work - but mine did work on Gordon's course

What was your terrain response set to on your driveway?

I also have not used extended mode since Gordons course but maybe I should practice. I remember the brake being required, I assume you followed the manual it might be the first thing the dealer asks. See the extract below.

EXTENDED MODE
If the vehicle's body is raised (e.g., by jacking)
or grounded in severe off-road conditions, the
system may automatically enter Extended mode.
Symbols in the raise/lower switch will flash and
the Message centre will display SUSPENSION
IN EXTENDED MODE. The suspension can rise
automatically to assist in clearing the obstacle.
Once Extended mode height has been achieved,
the driver may request additional lifting, if
required. This is achieved by pressing up and
holding the raise/lower switch for longer than
3 seconds, while pressing the brake pedal.
Extended mode is cancelled by pressing down
on the raise/lower switch or when the vehicle's
speed confirms that the body is no longer lifted
or grounded.

Agh normal - no special programs selected !!

I washe a few kilos of mud off it this morning and tried the extended/ emergency setting again. 1st try no luck. Then a reread of GOE book and found it said to be in rock crawl mode, did this and success!!!
So much easier to wash with the extra height!
I'm going to get some of GOEs height adjusters

Until you try to wash the roof!

Then you put it into access height

If you have Llams fitted then you can have access height -20mm at the turn of a knob, which feels like it is sitting on the bump stops.
Another good reason for Llams is you don't need a Jack or block of wood to get to extended height, again just a turn of the knob in the other direction.

Personally I reckon a Llams kit is the most useful and convenient accessory a D3/4/RRS can have fitted.
