Winter DRCC use temperature sensitive?

Maybe a connector is defective or for some other reason not making contact in the low temp? A trip to the dealer is in order IMO.

I have more rattles in the winter. The cold could have made something loose, or even break something.I'd have a dealer look at it. Until then, check the DRCC section of the manual, that should include the times the system won't work on purpose.

 

If you haven't tried to use the regular cruise control yet, you might want to double check that it is working even when the DRCC is unavailable.

Hold the Cruise Control button for 5 seconds for the regular cruise control functions.

This current weather situation sure is a learning experience for a lot of people, me included - I hope that goes without sayin.

 

This is just a wild guess, but I think I notice your fog lights are ON in the pics. Could it be this locks out DRCC because it thinks it can't see reliably in fog?

 

I leave my fog lights on all the time. That's never prevented me from using DRCC.

By the way, I'm guessing the "CA" in your location is for Canada, rather than California, correct? Maybe whatever function is preventing you from using DRCC is unique to Canadian cars, which is why we haven't seen it reported before in this forum, where most members are in the US.

I should also mention that I've tried to use DRCC in heavy rain (even though I think there is a warning against that in the manual), and I've noticed the car edging dangerously close to the car in front, to the point where I have to brake, convincing me that the radar system is not functioning at that point. This is all without seeing any messages on the dash.

 

Which of the 3 distance setting for DRCC ? Does it make a difference if set to 1 or 3?

I used DRCC for the first year or so, and it's OK most of the time. DRCC sure has some unique functions builtin. The one I thought was the most interesting was holding the cruise stick down for 5 seconds while traveling at highway speeds, then keep holding the cruise stick down until cruise shuts off at 28 mph. But you have to make sure there is nothing behind you when you do it.

 

On the highway, I generally use the middle setting, not trusting the system well enough to use the lowest setting (1), as I do when I'm in slower traffic. I'm quite sure I would have hit the car in front on those couple of occasions in heavy rain, if I was on setting 1. I was probably within a car length or 2, going 55 or 60 mph, when I hit the brakes. It was quite obvious the radar has lost its focus. I had been following at a speed considerably slower than the 65 I normally use when I set cruise control, and suddenly my car would begin to accelerate towards the car in front. Fortunately, each time the car in front was traveling at a constant speed. If it had also been braking, my car would not have escaped unscathed.

 

That's scary when the car accelerates towards an obstacle in front of it for no apparent reason.
I only switched out of the default distance setting a few times and it was way to close following for my comfort level, while in cruise. I don't mind following at most distances current traffic dictates, but sometimes it just gets nuts during rush.
Slushy roads and wet snow combination is another time DRCC messes up, but when it happened to me it gave me the warning on the MID.

 

Вітаю,чи вирішили проблему з DRCC.

 

"Congratulations on solving the problem with DRCC."

 

I asked how to solve the problem with DRCC, because I have such a problem with Prime.
