Well, am I the first victim of Californias new headlight law? You must now have your headlights on during the day - during rain.

It been raining for days locally. I've had my headlights, heater, radio - is there any thing else?

Now who thinks battery conservation, yeah I know short trips & this has happened to me before.

This morning - a dead battery. Called 800-Porsche for help; three times and circuits down no help. Called AAA direct got a boost within half hour. Less time than I wasted on 800 Porche....

It's too bad they have to legislate this.

It's common sense, yes. But driving in the pouring rain for the past few days, I see so many that still haven't figured it out. Turning on your lights in the rain actually DOES make it easier for others to see you.

You may consider buying one of those battery chargers that Porsche offers, especially if you drive infrequently

I'm not complaining about the law thats fine I always put my running lights on during rain. The s is my daily driver. Either PAG should reduce electric load or put bigger alternators in the single battery S.

Originally the S came with two batteries and no room for spare. Then it came with one battery and room for spare, I thought I was lucky to get one with room for spare. Boy was I wrong.

Last year the same thing happened after a rainy evening

BTW I have the tender and its great for my 996.

Just ventilating...........

That sucks Torags, I also have AAA plus havent cancelled it just in case thanks for the input on this. Doesnt Porsche roadside also uses AAA?

SF CAYENNE S 05

why we don't have day light running lights like on most suv vechicle i see out there?

alex911s

Can we do that option just by changing the headlight switch? Or do we have to have the Xenon option?

For my Carrera 4 I installed a DRL relay that was standard in cars shipped to Canada. Popped it in and now I have DRL's. I even get an insurance discount.

Is there anything like that for the Cayenne?

Canadian Cayennes have daytime running lights, so it should be an easy conversion.

BaysideC4

If it's as simple as installing a relay I would get it.

Yongster- Do the main headlights illuminate or do they use the fog lights as DRL's (like my 911)?

Torags

Yes they do. I like to call Pcar first so the call is noted. "first" listen to me, I'm talking like I have prior experience.... damn I do!

I think the problem is in the alternator output capacity. It seems the draw is greater than the output, so the battery is drained.

I wouldn't recommend turning on running lights during the day, especially if you're doing short trips.

Just my .02 based on my experience.

Have an 04 CS and use my Xenons every day (I live in Canada and as previously mentioned, they automatically come on). My commute to work is very short (10 mins) and I never had any issue. I am told that Xenons have long life so I would not worry about using them (I has them on my last 2 cars as well and never had issues). They make you a lot more visible than regular driving lights, even in regular daylight.

BaysideC4

ML,

I agree with you, they definitely make the car safer. Do you know if the US model can be retrofitted?

PTEC

From what I know, all Cayennes are capable of having DRLs, though you'll have to go to your dealership so they can "code" your car for DRLs.

ML

No idea, but suspect (like everything else on the car) that it can be done at a prohibitive cost!

BaysideC4

ML, Your probably right, thought the relay for my 911 was only $35
