    DRL Out When Turn Signals On

    OK, my DRLs turn off on whichever side the turn signals are activated. That DRL comes back on as soon as the turn signal stops. I've seen this occur with a CTS on the road and just assumed it was normal. However, today I noticed a 2011 SRX in my rear view mirror. It was turning. Both DRLs stayed on while the turn signal was active. I know it was 2011 because it was Mocha Steel, a color that didn't come out until 2011. Now I'm wondering if there is something wrong with mine, or if they changed this for 2011. Can everyone with a 2010 please check theirs and let me know if this is normal? If it's supposed to work like this, no biggie. I just need to know if I have to get this looked at. Thanks!

    Thanks for checking that, Steve. Either you and I coincidentally have the same defect, or they changed this for 2011. I'm leaning toward the latter. I'm trying to figure out if either design has an advantage, although it's nothing I plan on losing sleep over.

    When I first noticed this I decided it was a "feature" designed to draw attention to the flashing turn signal since it would be the only light that was illuminated on that side of the car.

    Wow! I thought the exact same thing, but dismissed that thought as rubbish. Thanks for reaffirming my original suspicion. Now that you mention it, the turn signal of the guy in my rear view mirror was harder to see with that DRL on.

    Nope, I don't think so. I'm referring specifically to the DRLs, not the regular headlights. The only option is to have them turn on automatically (Auto Setting), or to manually turn them off.

    Re: DRL Out When Turn Signals On

    Here's a link to a thread in the 2008+ CTS forum that discusses this item (i.e. same-side DRL turning off when turn signal is activated.. on vehicles equipped with the HID headlamp package). Post #5 explains it best. http://www.cadillacforums.com/forums...ng-lights.html

    It's puzzling why Cadillac would choose to change how DRL's operate on the 2011 SRX. Something seems to have been changed in body control computer software - either by intention or oversight.

    Other: As an aside.. note that the DRL's on Cadillacs built for Canada cannot be manually turned off. The only way to kill the DRL's on newer Cadillacs built for Canada (and equipped with HID headlamps) is to:
    a. Manually turn on the headlamps (which is something I sometimes do, depending on the day and/or driving mission) ..or..
    b. Remove the fuse(s) for DRL operation at the underhood fuse block (something I've never tried.. and wouldn't be legal to do in Canada)

    Re: DRL Out When Turn Signals On

    Good link, RAB! My guess is that it was by accident. The effects of changing a single command on any computer are manifold and often unanticipated in other systems. Still gotta look at mine today w/ headlites on/off, Auto/manual modes. fascinating tid-bit...........

    OK, that tells me that the SRX I saw had a defect. I wonder how long it will take the 2011 owners who have this defect to discover it. Everyone should check theirs, especially if you have a 2011 model.

    Thanks RAB and everyone else for clearing this up for me. It makes sense. I thinks the design team was ahead of the game on this one.

    This is normal, as previously stated, to allow the turn signal to stand out. This is not GM only.

    Re: DRL Out When Turn Signals On

    I believe this DRL off with blinkers effect is unique for the Premiums and above who have HIDs. Those with conventional headlamps systems (e.g. Luxury, base) have the DRLs up above at the 12:00 headlamp location; and the DRLs stay ON with blinkers. Is it possible Sube was looking at a 2011 Luxury SRX in Mocha??? This feature is even more dynamic on cars with LED DRLs (e.g. Audi A4) which takes out a row of lights to bring more attention to the turn signals. Those who have seen this; you know exactly what I'm talking about.

    Re: DRL Out When Turn Signals On

    I think ya nailed it mm9351 . I've seen the Audis. I was about to guess the fellow had put an LED light upgrade into the turn signal or DRL and left out a diode or something which affects power direction flow. Your explanation makes a lot of sense. Maybe some Lux owners will weigh in to confirm?
