Now you're really confusing me. "Settings"?? When I use the remote, (FOB), the headlights do flash on, and the horn beeps when I lock or unlock the vehicle. The headlights also come on temporarily when I put my hand on the handle to open the door and get in the car. I don't want or need any of this.

Is there a simple way to walk through the procedure to stop this nonsense? I would like for none of this to happen. That is have the lights stay off all the time, unless I have to drive at night. Call me crazy, but I always thought that's what headlights were for. And horns were to blow at people to get out of your way. Not to blink and beep when you lock and unlock your car. I didn't know this could be all disconnected. I see so many of the new cars doing this, I figured it was just something I had to live with. You know, like $45.00 a quart transmission fluid that used to cost $2.50.

I don't know because I never did. I thought the circle symbol, ("O"), was "MANUAL", but apparently not. Again, the owners manual is as clear as mud on this matter.

So..... You're saying if I crank the headlight knob all the way to the right, that is the "OFF" position? I ask because I've read and reread the owners manual regarding the function of the headlight "dial" or "knob", and nowhere is the word "OFF" even mentioned. God forbid someone unfamiliar with the vehicle drove it and simply wanted to turn the lights "OFF" by hand. I think a blind person has as a good of a shot operating this thing as a fighter pilot with 20/10 vision and night goggles.

Re: Fuel Tank Level & Fuel Pump Life ?

your lights will be off but possibly your daytime run lights are on of which you can only turn off by removing the fuse/relay its listed in the manual. also all other entry/exit settings are switchable via your personal settings.

I'm not going to pull any fuses, but I am going to read on shutting as much of this crap off with the U-Connect 8.4 as I possibly can. I think it's silly having all of these dual controls for everything like headlights, heater, A/C, and all this other stuff. This is so much overkill it reminds me of something devised by Rube Goldberg.

Re: Fuel Tank Level & Fuel Pump Life ?

the fuses have been designed to be pulled if you dont want them running!! it wouldnt be suggested in the manual if they didnt want you doing it.
might make your alternator stress less and last longer lmao yanks sure do stress alot you guys need to chill and live down under for sometime just maybe you brought the wrong vehicle and should have brought something a little more vintage obviously without all the ever worrying electronics, ie mechanical fuelpump and total loss ignition no alternator or rectifier to worry about

I have that in my 1991 F-150. When I want headlights I just pull the knob. When I want them off I push it in. In the middle of the steering wheel there is a picture of a horn...... Press it and it blows...... ONLY when you press it. I didn't think that needed "improvement".

On the main screen, press "controls", then "settings" on the screen that pops up:



Under the "Lights" menu, press the minus buttons on the first two controls to turn them to zero. Uncheck the rest.



Under "Doors and Locks", uncheck "Flash Lights with Lock" and "Sound Horn with Lock":



You can also turn off Passive Entry and disable the Power Lift Gate Alert beep by scrolling down to those options:



As far as the headlights, the switch needs to be in the second spot from the left to be "Off". Anything to the right of that are the manual on settings for Parking Lights and Headlights.

Re: Fuel Tank Level & Fuel Pump Life ?

Yes

You do not want to run the tank low or run it dry on the new returnless systems.

And the fuel does cool the pump, one of the reasons they put the pumps in the tanks and if you have ever replaced a pump in a 90's vintage tank, many still had external regulators and return lines, they have shielding in the tank with the return line to dump fuel back around the pump.

Good link
AGCO Automotive Repair Service - Baton Rouge, LA - Detailed Auto Topics - What Causes Fuel Pumps to Fail



"To cool and lubricate the internal components, fuel must flow continuously through the fuel pump. Insufficient flow limits cooling and lubrication of the pump. A leading cause of fuel pump failure is running the fuel tank low. This is particularly critical on late model vehicles without a fuel pressure return system. Running such a vehicle out of fuel once can permanently damage the fuel pump."

AGCO Automotive Repair Service - Baton Rouge, LA - Detailed Auto Topics - What Causes Fuel Pumps to Fail

A leading cause of fuel pump failure is running the fuel tank low. This is particularly critical on late model vehicles without a fuel pressure return system. A low fuel level also means less fuel to dissipate heat and lubricate the pump. The combination of an overworked pump, reduced cooling and lubrication will likely damage the fuel pump. Another factor is not allowing the tank to fall below one-quarter. Keeping the tank above this level can greatly extend the life of the fuel pump.
Thanks much for the link Turbo, very informative. It goes to show that sometimes people don't always know what they think they know. There are many reasons not to run around with a low fuel level. This is one of them.

Re: Fuel Tank Level & Fuel Pump Life ?

For those paranoid about fuel pumps burning up, let's try some simple math. Let's say you're driving down the road at 60 mph and you're averaging 15 mpg. So that means the fuel pump is moving 1 gallon of fuel every 15 minutes, or roughly one cup (8 ounces) per minute. It is not particularly hard on a pump to move 8 ounces per minute.

Relax and quit over-analyzing trivial things. I usually fill up between 1/8th and 1/4 of a tank. I've never replaced a fuel pump or had one fail.
