This is my first full day of playing with the Karma. I charged it overnight, and left today with a full charge and full tank of gas.
After a few seconds on the road, I realized that my CEL light was on in place of the speedometer. Uh oh! I pulled over and called the dealer, who said that it's nothing to worry about, they always do that on a full charge; go for a mile or two, and it goes away.
It turns out that he was right, except that it took more like 15 miles for it to go away. I toggled between Stealth and Sport a few times, but that didn't seem to make a difference. I drove to the in-laws, turned it off and turned it back on, and it was still there, but then I drove to a restaurant, went in to eat, and when I came back out the CEL went off and the speedometer came back.
Is he right that I just have to live with this each time I fully charge the battery? If so, does it really take 15 miles to go away, or does it vary based on temperature, speed, etc?
If it matters, I charged it using the portable charger that came with it on a 110V. I didn't do anything special when it finished; just unplugged it from the car, then the wall, then started the car.
If it really does take 15 miles to go away, is there any way to turn off the warning manually? The analog speedometer is a lot harder to read.
