 The accelerator handbrake combination works on my 2.2 (2008 build, 2010 registered) (tried it overnight) but I need to work on the technique as it's not smooth. I'm doing "push uncertainly, lift switch" which may be the problem

 What by pressing the foot brake?

Yes that always works, press the foot brake and lift up the handbrake lever at the same time to release the parking brake

To move off
With the engine running, release the electric parking brake, by pressing the brake pedal or the accelerator pedal and pulling then releasing the control

I think you might have a problem with and /or precedence

(pressing the brake pedal or the accelerator pedal) and pulling then releasing the control
not
pressing the brake pedal or (the accelerator pedal and pulling then releasing the control)


It also says
The gear lever can only be disengaged from position P if you are pressing the brake pedal.

Until this came up I always assumed it was foot brake only to release the hand brake.

I had a minor bump in C6 #1 because waiting on a hill I had my foot on the brake, and pulled the EPB a second time, then took my foot off the brake with the handbrake now dissengaged.

I still like the handbrake arrangement the XM had, even though you needed the footwork of Fred Astaire to do a hill start with a manual box

And I think I'm still going to use neutral at the lights even if is technically "wrong".

I read something similar about the auto box selecting neutral and it certainly feels as if there is no engine pull when stationary with the footbrake on - very different in my Merc 300GD Auto - when I select neutral in that at a set of traffic lights the engine revs. rise as the strain of pulling is released.



If the auto box selects 'neutral' then why does the dashboard indicator stay in drive?

When stopped on a hill in drive, foot brake on. Taking your foot off the brake should mean that the car rolls back, but it doesn't, it holds on the hill....

There is no engine note change, no car movement whilst it goes back into drive if it had decided by itself to go into neutral. That all means it's still in drive as far as far as I'm concerned.

The dashboard indicator will show the position of the gear selector, not the gearbox condition.

 It shows 'D' for drive so is still in drive mode.

 Tested today and can confirm that for a november 2006 (model 2007) C6 the parking brake will release with accelerator and parking brake control activation. Actually pretty good... Didn't know that.

About the Neutral / Drive discussion, in Drive mode (lever in D) and foot brake on for over 20 seconds at 0 speed causes the gearbox to no longer put torque on the wheels, it actually takes an annoying fraction of a second to get torque back on it (on slight hill: slight reverse and then creep forward after brake release).

At least that's my experience...

 Hmm, over 20 seconds, I'll try that out on mine to confirm

It would help explain some peoples comments about slow pick up when pulling out at junctions when they have been waiting for a gap in traffic.

brilliant explanation.

not noticed a delay? or perhaps not stationary for more that 20 secs in "D" foot on brake?

C6Dave I'll check this out.

 The handbrake technique also works in my '06. I'll practice using it.

 Hi

I checked mine out on a slight incline in "D" right foot on brake, released brake no throttle and no roll back. Just stayed put!

I don't think the tick over moved from the 650/700rpm, but will check next time I'm strating on an incline. (Essex) so not very often.
