Deep Sleep Mode

[HGH]

Our 2021 Navigator has been giving us Deep Sleep Mode notifications when we try to turn it on remotely. Is anyone else having that problem? We've had the car a little over a year.

Hi HGH and welcome to the Lincoln Forums. Deep sleep mode is activated in order to shut off non-critical power drains (including the ability to Remote Start), and save enough battery charge to allow the vehicle to start when necessary. The factors affecting and leading to "Deep Sleep Mode" being triggered are described in detail in the Owners Manual.

Some of them include...

- The vehicle not being started for a period of 14 days.
- Ambient temperatures. Freezing, below freezing conditions may cause it to occur within a shorter time span.
- The battery voltage falling below a predetermined level, as measured by the vehicle battery saver systems.

Essentially, "Deep Sleep Mode" being activated can be normal, according to the factors described above, along with how often and how far you are driving your vehicle on a regular basis (to keep the battery sufficiently charged). How often are you driving your vehicle, how far etc?
This feature serves a valid purpose. If the battery charge is beginning to be depleted due to any of the aforementioned variables (and possibly one or two more), it shuts down certain non-vital features which drain off battery power while the car sits unused for extended periods. It does this in order to try and save enough battery power to allow the car to be started next time it needs to be driven.

It can also be a sign of a weak/failing battery if it happens too often. Take a look at your Owners Manual description for more detail, then decide whether your battery may be on its way out.

And batteries can fail at any time. So if you feel this is occurring too often, t may be a good idea to set up a service appointment to have your battery tested. If it fails and you are within the 4 year/50,000 mile New Vehicle Warranty, it will be replaced under warranty.

Let us know how you make out and good luck.

I have had that problem twice of the past year. The battery was replaced each time. I believe something is using power while the vehicle is off as I sometimes get in and the screen tells me to turn the vehicle on or it is going to cut power.

Hi Ell. The message you are describing is normal and not a sign of a problem. It is simply telling you that the ignition is on, but will be turned off shortly if the vehicle is not started. It is part of the "Battery Saver" feature in our vehicles.

You may have some sort of parasitic battery drain, but that message does not necessarily mean you do. Inother words, it does not confirm or eliminate a battery/charging issue.

The messages and the meanings are described in our Owner Manuals.

If you still feel you do have some sort of parasitic drain issue, you should make a service appointment to have it looked at again.

Good luck.

That’s good info; thank you. I read the Corsair threads, and one owner mentioned that his key fob was too close to the car when it was parked in the garage and that the proximity sensing feature was reacting to the closeness of the fob (hanging on a key holder right inside the garage door). I’m moving the key fob further into the house to see if that will make any difference, and hopefully eliminate one of the drains on the battery.

Thank you for the info. We drive the car around 20-25 miles max at any given time, but mostly just trips to shop in the local area. This has happened in the cold (but garage doesn’t get below 45 degrees), and also in the heat of summer. This time of year we’re using seat and steering wheel heat daily.

Hi HGH. Moving the keyfob further away would not be a bad idea in general.

However, as the Owner Manual explains...After a preset number of "Lincoln Welcome Embrace" activations without the vehicle being entered and started (3...5...I forget at the moment?), the Battery Saver system shuts down that feature.

This is programmed in specifically to avoid such battery drain situations. For example: You are mowing the lawn and working in your yard with the keyfob in your pocketa nd your vehcle parked in the drivewway. In this scenario, every time you walk by the vehicle, all day long...perhaps dozens and dozens, your vehicle would light up and get ready to welcome you. But you have no intention of getting in, so it is simply wasted battery power.
So Lincoln has programmed the system to cease the welcome sequence after a set number of activations, without a vehicle entry and start-up.

So the key being within about 10' or so is not a huge worry. Further than ~10' and the vehicle can not sense its presence anyway. You can test the distance by slowly approaching your vehicle, and noting when the "Lincoln Embrace" lights illuminate.

But again, moving it further away certainly can not hurt.

Good luck.

I always have put my keys in a lead lined bag you can get on Amazon. Our cars are 15-20 feet away from the door we leave those on so I have found it better to just hide the keys protected from talking to the cars. Has worked great for years now with my other modern cars.

I am also a fan of connecting a trickle battery charger at night and when not using the car so that the 12 volt battery is always in tip top shape. I did that with my Sport Trac and my Fusion Hybrid. Never had a problem until I got lazy and did not drive the Sport Trac for 3 weeks and found fair new AGM gel battery dead. The various electronics are on all the time and they drain it. So now all my cars have a trickle battery charger (get them on Amazon or car parts dealers). This is quite common these days.

My battery was replaced twice under warranty for what it's worth.

Same here. Always keep a trickle charger on the Navigator when it’s not in use. Like you said, these cars always have some sort of drain on them- even if it’s small.

Thanks for the tip. I just went on Amazon and ordered a Faraday-type bag. I hadn't thought about needing the trickle charger, but think it is a good idea.

Hey, spend your money how you see fit, but I have none of these things and have never had any issues with my battery, 2 years in.

I agree. I just found that because I work at home it can we weeks between drives and at the time I had two vehicles so maybe one of them (the pickup) would sit for a month or more and the battery would go dead. I checked for any leakage but it was normal. It does have an alarm system and a camera that records activity around the truck so I know those both use power all the time.

Understandable that being the case. For me, someone who drives daily, just not something I would use.

Has anyone measured the battery voltage at the battery after it sits overnight?
After reading this thread i decided to measure my 21 black label L navigator this AM. 11.9 v.

I do not get any warnings and everything seems fine but i would rather see 12.25 or so.

Just a little confused.

No, I haven’t.

However, I do know that the center console interior light and the blue light in the wireless charging compartment remain on for 10 minutes after you exit the vehicle/open a door. Seems like a waste.

Not sure if this would drop the voltage that low, since I’m sure the drain is small; but it’s still a drain on the battery.

Battery technology has sure become much more complex in the last few decades with the advent of all the types other than the traditional flooded lead acid. For a AGM type which is what our 2021 Navigator has the following is the relationship of the measured voltage, a few hours after no load or charging, to its capacity or state of charge:

The voltage may vary depending on the manufacturer’s material, temperature, or new/old battery.

SOC(State of Charge)	OCV(Open-Circuit Voltage)
100%	12.85V
75%	12.55V
50%	12.25V
25%	11.95V
0%	11.65V

Table 01-SOC VS OCV

With all the loads being placed on our batteries in newer cars I think you'd be doing pretty good to get 4yrs out of a battery. If you drive infrequently or only do short trips your battery is not going last as long you might be used to from a car that you would have owned 5-10 years ago.

 

[Mark-P]

12.6 V is about the highest voltage i have ever measured on a battery that has sat a bit. Sure right after you turn the car off i can get a slightly higher voltage.

Even my brand new AGM camper batteries pulled off the trickle charger for more that 12 hours that are hooked up to nothing may only read 12.5 V.

I feel like hooked up to a vehicle a fully charged battery reads about 12.3 V.

Maybe i will get mine load tested and just aatch it for a while.

It may be worth trying to find the exact manufactures data for a specific AGM battery to fully understand their specifications and I'm sure you are also aware that AGM batteries require a "smart charger" one that knows how to vary the voltage and amperage base on the temperature and the battery's SOC, nothing seems to be as simple as it used to be.
