What handbook?

Although I don't think anything could have hit the switch because the van was empty as I was fetching it back from the garage.

Sometimes an effect from LED Lights on TV. The only appear to flash.

I clearly remember buying a used Mk III Zodiac fifty years ago, and the shock and confusion when first visiting a filling station. You'll be well ahead of me here, but that was my first car with the filler cap hidden behind the rear number plate. Took me a while to find :-)

The flicker you see on TV from some LEDs is much faster than flashers.

Making the tank ideally placed for a rear end shunt. ;-)

Trust me, I have never been in a Zodiac.

And it took me a while to work out how to open the Octavias glovebox.

And that's where the handbook is. ;-)

What got me going was how to replace a headlight bulb. As the headlight is inside the front wing. Eventually found a tool in the toolbox which pops the entire headlight unit out. Making it actually an easier job to change than some. After reading the handbook.

There probably isn't a switch as such. A lot use accelerometer chips like the ones in mobile phones. Its how the electronic stability programs work out what's happening.

They can detect sudden deceleration and turn the hazard lights on. Some do it for hard braking some only if you hit something.

The older Smart cars required you to remove the entire front to get to the headlight bulbs.

The newer ones don't.

I have a handbook for the Octavia but not for the Scudo.

The Octavia handbook says that the hazard lights will turn on if the airbags deploy.

Lots of cars had such badly placed tanks. Some were right at the front, much worse. The Pinto was if anything better than many others at the time, it just became the whipping boy.

I'd have thought it easier to use the ABS? That's only going to operate when you panic brake.

Just because you have activated the ABS doesn't mean you are braking hard or panicking.

Much better to use the sensors that they probably have for stability control. That's how they measure the yaw rate so they can use the ABS to correct for it. It obviously doesn't work on BMWs though.

So how then are you supposed to switch the hazards on manually when needed?

Not necessarily. It can deploy under lighter braking on a very slippery surface.

I think it's the Mondeo where you have to turn the Ford badge to open the bonnet.

12 year old Citroen C3 has that as well.

Twas a "Superb". It had James Bond water guns that emerged from the front bumper to wash the headlights!
