Does anyone else have trouble with lights. I live in the country with very dark roads and automatic lights do not work. I have been told by my dealer that where I live is too dark. Warning light come on saying crash detection not available even when I switch the lights to manual. My swift is one year old and previous swifts did not do this. Scary when you driving along and suddenly no full beam

It sounds to me like your dealer is BSing you.

Let me start by saying I'm not familiar with the newer Swifts, but, that said, most auto light systems (we've got three or four different vehicles with auto lights including a 2024 Jimny) are driven by an ambient light sensor on the dash, and they will NOT turn off because the road is too dark, if anything, they will turn on when you don't really need them.

I notice you say "suddenly no full beam", which makes me wonder if what you are calling "automatic lights" is a feature known as "high beam assist", which automatically switches between high & low beam and not the auto light feature that turns the lights on/off - suddenly no full beam should not be an issue, because when the full beam goes off the dipped beam should be on, which shouldn't be randomly switching unless there is a vehicle coming towards you.

Thank you and yes I mean high beam assist, I think as the switch is set on auto I presumed that was what you call it. I have been told that this will NOT work if it is too dark. Same thing happens in heavy rain. Have to change to manual in the dark but warning lights still keep coming on!!! Very frustrating. I have had it back at the dealers several times and they keep saying nothing is wrong. Is there a Suzuki customer service?

I agree with Fordem the lights should NOT turn off because the road is too dark the dealer is lying.
Is there a Suzuki customer service

Auto lights (not high beam assist) has been around for literally decades and in my experience, it doesn't cause an issue if the roads are too dark, the lights will just come on and stay on - when the systems first came out, if you drove under an overpass the momentary change in light intensity could trigger the system causing the headlights to flash on & off, which confused some drivers and the solution to that was to build a time delay into them, turn the lights on immediately, but hold them on for five or ten seconds. It's now what I would call tried & proven technology.

High beam assist is much newer and part of a suite of features known collectively as ADAS or Advanced Driver Assist Systems, the intent being to make motor vehicles safer, but I feel it has the opposite effect. The technology to a large extent is unreliable, and whilst it is optional, if the manufacturers don't fit it, they end up with a lower NCAP safety rating and lose sales to brands that do. As mentioned earlier, even if the high beam assist switches to low beam suddenly the lights should not go out, I understand it can be disconcerting, but it is what it is. Presumably you still have an option to manually select low beam - the turn signal stalk should have three positions, so to speak, front to rear, furthest away from you is high beam, mid is low beam, and toward you flashes the high beams - what happens if you drive with it in the low beam position?

If I drive with the low beam and I manually put on high beam because it is dark the lights are fine. But the warning still come on the screen that collision detection is not available and flashes on and off. This is very distracting. If as you say this is how it is then it's a backwards step. My previous swift (2019 model) worked fine as did my previous one to this. Dealer keeps saying I live on area with no street lights or cats eyes and in some cases no white centre light and this confuses the car!!! Surely not

Let's back track for a minute - this discussion started with automatic lights and whilst you did mention the crash/collision detection message the focus so far (or my focus so far) has been on determining what you mean by automatic lights, I believe we have established that it's high beam assist, and as far as the high beam assist goes, that is what it is.

Your last post seems to suggest that your concern has nothing to do with either automatic lights or high beam assist, but rather with a crash/collision detection not available message, and quite frankly I am puzzled as to what the linkage between the two is. Collision detection/avoidance, as far as I know, is not linked to the automatic lighting features other than they are both part of the ADAS suite, and I'm not going to suggest to you that that is how it should work. I am, however, going to point you back to your owner's manual, there will be a list of conditions that can trigger that message, which I believe on a Swift will include such things as a dirty windscreen - I believe the Swift uses a pair of "stereoscopic" cameras mounted up on the windscreen near the rear view mirror and the system is prone to issues when those cameras do not have a clear view of the road ahead.

That list is also going to recommend you go back to the dealer, which you have done, and if you get no satisfaction there escalating to Suzuki GB would be the appropriate action.
