Default T82 Twilight Option - Software error?

Hello,

I just got the T82 option enabled in my Z06. I noticed that it is not possible to set a "lights on delay". That was no surprise, as I had read about that here on the forum before. However, to my BIG surprise, the 2004 Owner's Manual says otherwise:

Press the OPTIONS button until TWILIGHT-OFF
appears on the display, then use the RESET button to
page through the following selections:
• TWILIGHT – ON
• TWILIGHT – OFF
If you choose TWILIGHT – ON, press the OPTIONS
button again to display DELAY TIME 1 2 in the DIC.
Use the OPTIONS button to switch between delay time
1 and 2. You can increase the delay time by pressing
button 1 (1 FUEL) or decrease the time by pressing
button 2 (2 GAGES). Each bar is equal to 12 seconds.

Notice the statement saying "Use the OPTIONS button to switch between delay time 1 and 2". It sounds like the designer originally intended us to be able to set a "lights up delay (1)" and a "lights down delay (2)" (the arrow up and arrow down also appropriately indicate this). However, it seems like due to a programming and/or design error, this was never correctly implemented. Who knows, maybe the feature is already there, all implemented, but inaccessible. (The TRIP button should switch between 1/2, not the OPTIONS button since it takes us to the next option).

Having a "lights on" delay would make this feature much more valuable. However, with the lights coming on instantly, without delay, I have to agree with all people here in the forum that find it annoying...

Does anyone have more info about the Twilight option? Is the manual wrong, or is it simply a software bug that never got fixed?

The Twilight Sentinel in our car appears to work exactly as outlined in the Owner's Manual. Granted the instructions you quoted above from the manual may be a little hard to follow and I think you may be misinterpreting what they are really saying. The DELAY TIME 1 2 in this case is not signifying that there are 2 different delay times and the "Up" and "Down" arrows are not used in reference to the positions of the headlights. Rather the number 1 with the "Up" arrow beside it is saying to use the number 1 FUEL button to increase (thus the meaning of the "UP" arrow) the delay time. The number 2 with the "Down" arrow beside it is saying to use the number 2 GAGES button to decrease (thus the meaning of the "Down" arrow) the delay time. (Note that each of the five buttons used for control/setting of the DIC is numbered 1 through 5 along with the function name.)

Also, the '03 Owner's Manual contains additional information under the heading Twilight Sentinel (Optional in United States, Standard in Canada) on page 3-15. (Check the index of your '04 Owner's Manual for this heading/information and page number for your manual.) Here are a few excerpts from this passage in the '03 manual:

When Twilight Sentinel is turned on, you will see the following happen:
[list]
When it's dark enough outside, the front turn signal lamps (DRL) will go off, and the headlamps and parking lamps will come on. The other lamps that come on with the headlamps will also come on.
[/list
    Twilight Sentinel also provides exterior illumination as you leave the vehicle. If Twilight Sentinel has turned on the lamps when you turn off the ignition, your lamps will remain on until:

        See Driver Information Center (DIC) on page 3-44 to select the delay time that you want. You can also select no delay time.
        Hope this helps.

        The Twilight Sentinel in our car appears to work as outlined in the Owner's Manual. Granted the instructions from the manual which you quoted above are hard to follow as written and I can see where one could easily misinterpret what they are trying to say. The DELAY TIME 1 2 in this case is not signifying that there are two different delay times and the "Up" and "Down" arrows are not used in reference to the positions of the headlights. Rather, the number 1 with the "Up" arrow beside it is saying to use the number 1 FUEL button to increase (thus the meaning of the "UP" arrow) the delay time.

(Note that each of the first five buttons used for control/setting of the DIC is numbered 1 through 5 along with the function name.) Try playing with the delay time, setting it up and down, and I think you will see what the instructions are attempting to say, albeit not very well.

        Also, the '03 Owner's Manual contains additional information under the heading Twilight Sentinel (Optional in United States, Standard in Canada) on page 3-15. (Check the index of your '04 Owner's Manual for this heading/information and page number for your manual.) Here are a few excerpts from this passage in the '03 manual:

        • When it's dark enough outside, the front turn signal lamps (DRL) will go off, and the headlamps and parking lamps will come on. The other lamps that come on with the headlamps will also come on.

        • When it's bright enough outside, the headlamps will go off, and the front turn signal lamps (DRL) will come on, as long as the exterior lamp switch is in the OFF positions.
        If you start your vehicle in a dark garage, the automatic headlamp system will come on immediately. Once you leave the garage, it will take approximately one minute for the automatic headlamp system to change to DRL if it is light outside........
        Twilight Sentinel also provides exterior illumination as you leave the vehicle. If Twilight Sentinel has turned on the lamps when you turn off the ignition, your lamps will remain on until:
        • The exterior lamp switch is moved from OFF to the parking lamp position, or

        • a delay time that you selected has elapsed.
        See Driver Information Center (DIC) on page 3-44 to select the delay time that you want. You can also select no delay time.
        Hope this helps.
