Parking Sensors

Stagone · November 8, 2014

Purchased a second hand Lexus is 250 this week (2006) United Kingdom

I cannot set parking sensors as per manual because satellite switch only shows speed and tach settings.

Any help please?

Also have trouble locking it. Press lock on fob and it does not lock

Your car may not have the full parking assist sensor system. Do you just have rear sensors, or front ones too?

My car just has rear sensors, which beep as you'd expect, but that's it. And my satellite switch only allows speed and tach settings.

Fob - maybe the Battery is failing - do you have two fobs? Does the other one work? Try replacing the Battery or batteries - CR1625.

You can always just press the button on the door handle (once for normal lock, twice for deadlock). I never use the fob locking function. (But it does work)

Thanks John. When car was purchased I was told it had front/rear sensors. Re the locking problem I will give what you say a try..

Thanks

Yes - but does it actually have the front sensors? You can see them if it does - little circular things in the bumper - as in the rear (although not all IS250s have them either!)

With John on this one

2007 seems to be a facelift year - mine has the 4 fitted but I have noticed when looking for parts for the car from this year that there are a couple of options especially for parts for the braking system.

Do the pre 2007 models have the reversing camera fitted which links to the rear sensors?

Stagone · November 9, 2014

John it does have the sensors circular near front t bumper. perplexing this

is200 Newbie · November 9, 2014

If that's the case and you do have the front and back parking sensors fitted (which is the same as mine) then I have an option for adjusting the range the sensors activate on the main console unit amoungst other sensor settings (through the touchscreen) along with the driving distance sensor you can adjust the settings here.

Not sure what menu its under but its definitely on there (I would go have a look but its raining at the moment ... will get my hair wet !!!)

Have a look through your manual for the option.

johnatg · November 9, 2014

It depends on whether the car is a (rare) basic IS250, a SE or a SE-L. Mine is an SE - doesn't have touchscreen, nav, etc and doesn't have front parking sensors. (OK - I know - but less to go wrong! :eerrrmm: )

I don't think there was an actual facelift in 2007 - the main change was to rear brakes - went from solid discs to ventilated - not sure at what VIN. (Fronts of course always ventilated)

Stagone · November 9, 2014

Its a late 2006 and does not have touchscreen. Its is 250. It has satellite switch but this only adjusts speed and tach.

johnatg · November 10, 2014

It'll be a SE. It should say that in the V5, but I guess you won't have that yet. Anyway, not definitive.

I think you won't have the adjustable parking sensors - just the basic operation ones front and rear. As I said, mine just has the rear ones (it is an SE).

So now just down to the lock function of the fob(s). Let us know how you get on!

Stagone · November 10, 2014

Thanks John not got V5 back yet will check when it arrives.

Will try the locks today, poured down here all weekend. Many thanks

Hi sorry sorry for delay

It is SE (GSE) found small button size toggle switch under dash RHS and this switches front sensors on.

Re locking I have worked this out

Many thanks Stagone

I have exactly the same problem as Stagone and would appreciate any advice: 2008 (57) IS 250 SE. Have the sensors (or what looks very much like them!) on the rear bumper only - satellite buttons show only revs and speed indication. They may be automatic but upon reversing against anything - like a wall - nothing happens! Is there a fuse to check, maybe?

Linas.P · December 8, 2016

I have 2008 SE-L, both front and rear sensors, but without navigation/touchscreen and I have no sensor sensitivity adjustment either. Maybe that is related to navigation then? Other question is it AT or MT?

I was never aware there was IS250 .. full stop. John do you have more details? I though for pre-facelift it was only SE, SE-L and Sport, later SR.

On mine I can adjust sound,distance from my sat Nav touch screen and got sensors back @ front. linus is right only adjust through touch screen

On my is220d had sensors back and front but couldn't adjust sound,distances had no sat sav.

My 2010 250 sei with sat nav only has the reverse camera. Even though I have the sensors fitted to the front I only have rear park assistance or maybe I'm missing something .

Linas.P · December 8, 2016

Not sure what you mean by parking assistance. So I guess you have visual guidance on your rear view camera and in front you only have beeping sound which would be expected.

Shahpor · December 8, 2016

Do you have the green light on the bottom right of the instrument cluster lit up?

If you have the front parking sensors, it should alert you when something is close (up to 5mph). Annoyingly, at least on mine, the sensors don't seem to cover the front bumper straight ahead with only the corners being monitored.

Linas.P · December 8, 2016

Same for me, few times I have literally touched something with my number plates. There is dead zone in the rear as well, if you parking by the metal rails of certain height sensors doesn't see them..

peachy · December 8, 2016

If my car does have front sensors than they don't work .the green light comes on the dash when activated from the satellite switch but the beeps don't activate no matter how close I park up to an obstacle .

Shahpor · December 8, 2016

Does the multi function display in the cluster not change to show something is close? Should flash up showing which corner is near to anything.

is200 Newbie · December 8, 2016

Is there an option to turn the sound off - also an option for the back sensors only I think to set the operating distance

peachy · December 8, 2016

Actually I've just had a play with the sensors . It's does actually bleep when it detects anything near the front side of the car but nothing directly ahead of the vehicle . is this normal ?

Shahpor · December 8, 2016

This was mentioned above.

There doesn't seem to be any sensor coverage on the front of the bumper, just at the sides.

Linas.P · December 9, 2016

Yes, because there are 4 sensors on the back and only 2 in the front (sides). By the way it is typical arrangement on many cars as I guess it is expected that driver should see what is directly in front of the car.

This is example of my "lucky" park when rear sensors didn't detect the barrier:
