Sniffing around on the ol' interweb,
If your car is a US car, Press the Options button until TWILIGHT-ON appears. Then using the RESET button, page through the options:
TWILIGHT - ON
TWILIGHT - OFF
With TWILIGHT - ON selected, if you press the OPTIONS button it will display DELAY TIME 1 2. You can increase or decrease the delay time using buttons #1 (FUEL) and #2 (GAGES). This will increase or decrease the bars shown on the display. The more bars, the longer the delay the fewer the bars the less delay time. Each bar equals 12 seconds.
If you cannot get to the TWILIGHT option, your car is a Canadian car and as you know, you'll have to have someone change it to a US car.
Depending on the year, others found that you can just pull fuse #44 in the passenger foot well, however, your front corner lights won't flash when you lock the car and your DRL's also won't light up when the car is running but everything else should work properly. I've never tired this or seen this, this is all just what I have read so I can't verify if this is valid or not.
