Only picked up my RRS 2012 today and awaiting a copy of the owners manual to arrive in the post so apologies for the silly questions

It's currently in the high setting, does it make any difference if I drive it day to day in the low setting?

Does it add any extra wear and tear to either setting?

PS - will get some pics of my motor up on here asap

There are three basic heights: access, normal, off road.

Access height is available only at low speed and the car will automatically raise to normal height once the speed threshold is reached.

Normal height is the day-to-day height. This is what the car defaults to.

Off road is a raised height intended to give increased ground clearance when on uneven terrain. Off road height has a speed limitation as well and will automatically drop back to normal height if the speed threshold is reached.

You can lock access height at very low speeds e.g. for getting in to low car parks, but it won't stay there if you speed up. Off road height increase if the car thinks it's bottomed out (stuck on a rock, for example). This mode (extended mode) is not driver selectable and only happens automatically. There is an additional super extended mode aka "give me whatever height is left in the suspension" that can selected once extended mode has been activated.

You can change the default settings in three ways - using rods (these replace the links in the height sensors and fool the system in to thinking it's at a particular height); using software such as an IID Tool to calibrate the height up or down; or by using a third party device that sits in the wiring and allows the driver to select any height he wants whenever he wants.

A 2012 will sit in normal mode all the time unless you ask it to change using the ride height switch on the centre console. Some people will select access height as they approach a parking spot to make getting in and out easier. Most don't bother. Most have never likely used off road height as they never go off road. And almost no one will have seen / needed the extended mode or the super extended mode.

If you want to fool the car in to giving you extended mode, go to off road height, place an axle stand (or a brick) under the cill and ask it to lower to normal height. It will detect the obstruction and raise to extended mode. You can then apply the footbrake and the height raise button for at least 3 seconds to go in to super extended mode.

Whenever you're moving between heights, don't do it in park. As the suspension raises and lowers, the effective wheelbase changes (not by much) and a lot of strain is put in to the components unless they're able to rotate/move. Best to do any changes when moving slowly if possible. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

I put together a PDF copy of the Owner's Handbook and Quick Start Guide for the 2012/13 cars, which you can download from here if you wish.

Wow, thanks for this reply, very useful and good to know. Cheers

Many thanks for this Col, I'll have a flick through some of the sections while I wait for the hard copy to come through

I never knew this and had been doing so - just without the brake on. Thank you

Never bothered about vehicle moving, only ever changed it with brakes off and transmission in neutral if I've wanted to change it, although never really use it that much.

Cheers

Yes Col, brakes off, transmission in neutral is just as good, but I to tell people to do it on the move as many sit with a foot on the brake unconsciously when stationary with the engine running. By moving slowly, you know nothing is going to get stressed in the suspension. 2012 SDV6 - it's missing a couple of cylinders

What setting do we set the RRS from the control buttons inside? I do not have an owners manual sorry

Just leave them alone.

It will adjust automatically for road use
