Re: The Best, Least-Known Tips & Tricks

Arnis, I think we are talking about two different things. In Auto CC mode the car may well be choosing a partial recirculate mode as it sees fit. Most of us don't use Auto Mode, though, because it likes to draw lots of power. The Partial Recirculate mode to which the FAQ refers is manually engaged with the climate control in one of the manual modes.

If you click AUTO and then select fan speed, temperature or even direction, recirculation still stays in auto.
It doesn't default back to fresh if AUTO LED is not lit.


AUTO mode is not some special mode that draws power. It just tries to maintain selected temperature.
This is why one should reduce temperature selection. CC understands that and will lower fan speed on its own
(after warmup cycle). It is possible to reduce consumption if fan speed is reduced (not always true for hybrid heater).

PS! Holding recirc button does not activate "partial recirculation mode", it activates "automatic recirculation mode" aka
the same mode that is activated with AUTO button. During summertime holding recirc will not engage any recirc.

I find that Auto seems to overdo it for me. I wish there were a 50° selection. When it's super cold outside and inside it doesn't matter if I set it at 60°F or 90°F. The heater runs full blast. And since we have to dress for -20°F weather by the time it warms up to 60°F it actually seems too hot. 50°F would be just about right.

The undertray is made from some kind of fiberboard and simply tore. Most likely caused by the previous owner pulling too far into parking barriers or curbs and scraping it repeatedly. Just throwing away kilowatts with this not fastened correctly.


My Wife had the same issue with hers. Called the dealer, $130 for the part. I'm thinking about it. I want to wait until the winter is over to fix what is left of the tray.

Exactly. This is correct. I would recommend enabling full recirculation mode in auto+lowest temp setting+feet. Up until it starts to fog up.
This will speed up heatup and also will limit heating element even more (due to the fact that input air gets very warm very fast).
The more/faster drivers footwell heats up the faster CC thinks "enough of full blast hot". Temp sensor is there.
If you don't have heat pump then it is also reasonable to reduce fan speed to maybe 2-3 bars. With heat pump down to 4 bars.
Feet only direction will heat up the sensor faster and will reduce heating sooner.
Low fan speed (AFAIK) speeds up water heating element degradation. It does have "max temp setting" but that is reached way
too fast if air doesn't cool down return coolant. Air PTC element also just stops as soon as it gets to max temp (105C I believe),
but it is not so prone to failure.

PS! I believe it is possible to adjust displayed temperature to real sensor data. Ask dealer to adjust CC temperature selection display value.
Depends what is the lowest cabin temperature sensor limit, it might work. BMW for example has +10C as minimum sensor value,
16C as minimum selection. But it can be adjusted so 16C shown actually means for example keeping 13C in the cabin.

Of course the best way to is to preheat the vehicle for 5 minutes. This dramatically reduces peak load at startup.
It is also much more efficient than heating while driving due to recirculation activated most of the time, with no fogging up.

IF this is the case for you then it's either different for the 2016 SV or different for Europe. Here in the US the Recirculate button acts the same regardless of season. And again, most of us would rather tell the car what we want via the Mode buttons than tell the car "Auto!" and then try to restrain its exuberance with multiple adjustments.

This post is to "bump" the topic up, and explain how to use it. Those looking for Leaf driving Tips & Tricks just have to go to the first post in this topic and read that. The rest is discussion of that FAQ-type document.

On Page 4-26 of the US Leaf manual it states that the press and hold engages auto mode. The intake flap will operate the same as it does in full auto. So in summer it may indeed be full open. I know when the AC system starts in auto in the summer it is on recirculate for a time so there may be some modulation of the flap.
I do know to engage the auto re circulation mode you must first press to engage full recirculate. then press and hold till the light flashes.
Hope this clears up some missunderstandings.
