Let's try and clear this up once and for all.
Don’t know if I am setting the bar high or low with my experience!
Jazz, ,May22, EX, Manual gearbox, (I lied about that bit, but at least I have your attention) , 3200 miles.
Arrived back in the U.K. a fortnight ago, having left my car, parked up, on my driveway, for 29 days.
Looking at the Manchester weather, from sunnier climes,( as you do ); I saw that they were having the equivalent of, The Beast from the East. It’s difficult not to feel smug, but I try.
The bones of all this...
I always park the car in the drive at home, with the electric handbrake off. This saves that annoying clunk, when you first drive away; the pads having glued themselves to the discs.
The only other thing, that is not automatic for me, is that I switched off the keys. (Thanks for the tip on here)
I always turn off the headlights last job, to save that last 15 seconds depletion of the 12v. battery.
So there we have it. A month in bitterly cold weather. (The car, not me!)
Without any hesitation, pushed the launch button, YES, and reversed out of the drive, cleaning the rust off the discs as I went.
So the only 12v. battery saving, that I am SURE gives a small help, is the lights off.
So there’s my experience, a month in the bitter cold, without the starting handle, or the AA.
Just love the car.
