Problem with front screen misting up using auto stop/start
2 2

12 posts in this topic

Afternoon,

Does anyone else have a problem with the front windscreen misting up when your vehicle is stationary with auto stop/start activated? Aircon and air recirculation on at the time.

 

My signature nav does it all the time, yesterday I had to drive off in a line of traffic with the screen misted up having been at a standstill for no more than 2 mins, which was a bit iffy as we were heading towards the sun set and I couldn't see a great deal.

 

Interested to see if I am doing something wrong or if it is a common occurrence with the Kadjar.

Thank you for the advice. Aircon on it is from now on. :)

I believe that if you have the front and/or rear screen demist function activated, it disables the auto start/stop.

Wonder if this is why the stop/start sometimes doesn't activate?

Our previous car had start/stop function and didn't activate if the aircon was required also if the engine was cold, that said it used to have a little indicator on the dash board informing you that the function was enabled.

Certain conditions prevent the system

from using the engine standby function,

including when:

– reverse gear is engaged;

– the bonnet is not locked;

– the driver’s door is not closed;

– the driver’s seatbelt is not fastened;

– the outdoor temperature is too low or

too high (less than around 0 °C or

higher than around 30 °C);

– the battery is not sufficiently charged;

– if available, “4WD Lock” mode is

activated (please see the section

“Transmission: 4-wheel drive (4WD)”

in Section 2);

– the difference between the vehicle

interior temperature and the automatic

climate control instruction is

– parking distance control is in operation;

 

– for vehicles with automatic gearboxes,

the gradient is steeper than

approximately 12%;

– the “Clear View” function is activated

(please see “Automatic Climate

Control” in Section 3);

– the engine temperature is too low;

– the emission control system is being

regenerated;

I suspect it's the air recirculation that's the problem.  I've done around 4000 miles in my car and not had this happen at all whether the air con or the climate control is activated but I don't have recirculation on.

I've never used recirculation since I found out it causes the car to mist up. If you think about it, all the air exhaled by the occupant(s) contains moisture, so recirc just moves it back into the car. Turn it off, turn aircon on & the issue will go away.

I have the problem in slow traffic with ECO on. This is generally the energy saving side as its switching off the Aircon more frequently to save fuel and not maintaining such tight tolerance on the ambient temp stabilization. The end result is you air con off most of the time and the Renault system seems to be quite aggressive at it.

 

I find it really bad when its raining out.
