Question about parking sensors

[ajstan]

Hi there, just bought a 56 Mondeo with rear parking sensors and they're not working quite as expected - just wondered if someone could advise me as they're totally new to me.

When reversing I start to hear the intermittent tone at about 90cm and then it gets faster until about 30cm when it becomes a solid tone.

I assumed the solid tone is supposed to sound when I'm more like 0.5cm away from an object? Am I right? Can they just be adjusted easily?

Any help much appreciated

Have you tried giving them a clean? Sometimes when dirty they can not operate to normal levels.

thats how they work. Given that no sensor is perfect they cannot risk letting you get too close.

Thanks for the speedy reply, I'll clean them tomorrow morning and report back.

30 cm is normal

The ones on the vans at work make a solid beep at around 30cm, so I assume thats normal?

 

[ajstan]

OK thanks all. I just assumed they'd be a bit more accurate than that

0.5cm ? hope you have exceptional pedal control

My mondeo is the same. I would prefer it to be about 150cm myself.

My Mondeo is the same for both front and rear. The solid tone sounds at approx 30cm/1ft. Plenty of room

Yep, I agree. My Mondeo produces a solid tone at 30cm too.

My BMW also gives a solid tone at roughly 30cm, its the norm!

You want a solid beep at 0.5cm?..
..
You must have lightning reactions man.

And when you've parked 0.5cm from the car and the next mondeo comes along and parks 0.5cm from you and you then return to your car and wish to leave, what do you do?

My merc does the solid tone at about 10cm

30 cm is next to useless!

I would argue that a woman in stupid shoes needs at least 30cm before ramming the car behind!!

I found this out when I reversed a Merc in to a post in a car park - I was used to going a certain amount over the solid beep

I'm with you op - graduated indication down to ~15cm would be much more useful. Unfortunately these things have to be designed to the lowest common denominator (with the clumpiest feet/rubbish flappy paddle box )

Might as well not have sensors!
