Huh? TC system is a four wheel system and I wouldn't think it would matter wether or not they are disc or drum. I wonder if drums are used on a Fusion AWD with TC?

If it's a 4WD it will have rear brake drums but I think that if its only a FWD, all be disc brakes.

That may not always be true as far as the CAN buss system goes. During my continuing quest for knowledge on the Escape 4WD systems, I pulled the fuse for the 4WD module. That lites the wrench dash icon, replacing the fuse turns it OFF. CarlD told me what magical numbers to plug into my SG-II and it seems that the DTC was still there. Some DTCs will remain till the said code that turned it ON "sees" that the problem no longer exsists. It's possible that I didn't drive it enough after replacing the fuse. The CAN buss system seems to retain faults even though there are no dash indicators showing any problems. Since there was the 4WD module DTC stuck in the system, was the 4WD system operating correctly? I don't know!! Again CarlD told me what magical numbers to program into my SG-II to clear that DTC from my vehicle.

The following from the Tire Rack is like most others found doing a simple search on tire pressure. Yeah, run higher pressure if your racing on a smooth track but that's it! Some say that overinflation reduces braking, some don't. Disadvantages of Underinflation An underinflated tire can't maintain its shape and becomes flatter than intended while in contact with the road. If a vehicle's tires are underinflated by only 6 psi it could weaken the tire's internal structure and eventually lead to tire failure. Lower inflation pressures will allow more deflection as the tire rolls. This will build up more internal heat, increase rolling resistance (causing a reduction in fuel economy of up to 5%) and reduce the tire's tread life by as much as 25% while increasing the probability of irregular treadwear. Drivers would also find a noteworthy loss of steering precision and cornering stability. While 6 psi doesn't seem excessively low, it typically represents about 20% of a passenger car tire's recommended pressure. Disadvantages of Overinflation An overinflated tire is stiff and unyielding and the size of its footprint in contact with the road is reduced. If a vehicle's tires are overinflated by 6 psi, they could be damaged more easily when encountering potholes or debris in the road, as well as experience irregular tread wear. Higher inflated tires cannot isolate road irregularities as well causing the vehicle to ride harsher and transmit more noise into its interior. However, higher inflation pressures reduce rolling resistance slightly and typically provide a slight improvement in steering response and cornering stability. This is why participants who use street tires in autocrosses, track events and road races run higher than normal inflation pressures.

I don't know about all that data. If this was the case, everybody would be running 50psi. Had a friend that ran a high pressure in his tires on a F-250 and I commented that'll burn the center of the rear tires. Sometime later he said that the cords were showing on his rear tires! I just smiled. So if you don't do that on your family car, you must strictly be after the increased milage, correct? You wouldn't make two miles where I live driving on 50psi. I remember one time in my '97 Ranger Splash SuperCab 4X4 after getting a oil change. I hit some kind of bump or something with both front/back wheels on one side. It darn near turned me sideways and scared me to death! I got home and checked my air pressure in my tires and they were way over MAX. Not me, you can keep your extra MPG.

The times that I called, no problem at all. I was even told to wait closer to my 6 month expire date as I'd receive better deals in the mail. I was also told with the Lifetime Plan after three years, it's free. Although 6 months later the Lifetime Plan price went up a bit and now is free after 3 1/2 years.

I'm sure that 50psi is way above what's marked on your door sticker for unloaded but not sure what tires your running but that still seems a bit high! I assume your doing this just for milage sake? Doesn't it ride like a pogostick?

I ran across a website one time that explains the different 4WD/AWD systems out there and mentioned some of the vehicles that use each system. None of the systems described works like the Ford Escape does! The difference is in "when" its enabled more than how it's powered.

Well, 4WD is driven by a PTU which is a transmission output. What drives the transmission at that time? It really could be either but I'm pretty sure that there is only one electric motor and no seperate motor for the rear wheels.

I was under the impression that "only" driving conditions with front wheel slippage would enable the 4WD but that isn't the case. Frankly, I don't see the point of enabling 4WD on dry pavement. I'm almost looking forward to winter and some snow to see how much rear wheel I really get.

There's no basic difference in operation of 4WD between the a Hybrid and non-Hybrid. Both have a elctro-mechanical clutch in the rearend driven by a PTU. I started a thread at GreenHybrid about 4WD in both. All kinds of theories came up and I think somebody also mentioned a seperate motor for the rear wheel but that disproved. Here's a link to the thread: GH thread Are you sure your not confused with the electric motor being used in reverse??

I don't own a FEH but it is 4WD FE and have monitored the rear wheel torque with a scope connected to the output on the 4WD module. I have a Scanguage II setup to monitor rear wheel torque now which I've adjusted to match my scope readings. The 4WD engages every time you leave a dead stop, most often reaching 25% or so and slowly drops to zero as you reach a steady cruising speed. At a steady speed no torque goes to the rear wheels.

It sure is in the video but sure not where it's at in a Fusion! Sure looks like a awkward spot to reach with either hand, doesn't it??

You had better reread that yourself! That says the same thing as a Mariner, inboard side of the seat back with a picture of the knob only and not of where it is located. But the Fusion has a picture of the knob on the side of the seat cushion near the front. I'm just not sure where the inboard side of the seat back is!

Pictures, showing what? The Fusion owner's manual shows the lumbar knob on the door side of the seat cushion. In the '09 Mariner owner's manual there aren't even any pictures. It just gives the location of on the inboard side of the seat back. Would that put it between the seat and the console? Hardly room for a hand to get in there.

The 2009 Mariner owner's manual describes the manual lumbar support but the 2009 Mariner Hybrid doesn't! The particular site I was at doesn't list the 2010s yet.

The '09 brochure and window sticker refer to it as a six-way power driver's seat with no lumbar mentioned. The six-way power set either comes with it or not! I never heard of this before until mentioned in this thread and somebody said that the Mariner has it. I started looking and found the "six-way power lumbar/manual" mentioned for the Escape, Mariner and Fusion. The knob is shown in the Fusion owner's manual but not in the Escape owner's manual. I don't remember the exact site where this was listed but it was one associated with Ford.

I assume that's what they mean because that's all there is. Lumbar/Manual is listed for my vehicle along with the 6-position power seat but there isn't any knob!

Yes way! This is right from the features on a '09 Escape and Ford refers to it as "lumbar/manual" and I think that's where the confusion lies! I wouldn't call that a manual lumber support at all but that's what Ford calls it.

On a six-position electric seat, Ford calls that lever that tilts the back in steps as lumbar/manual.

I found out several weeks ago that I had access to the TSBs themselves and didn't even know it!

I have a Husky Cargo Liner listed for the '08 in my '09 but I'm unsure if you can say that a '06 would fit! I called Husky and asked about the Weather Beater floor mats for my '09 and was told that nothing was available yet. Your saying that they were wrong, correct? I know that they are available now.

I didn't know there was a way to even look at titles. I've been watching/waiting for AllDataDIY to add the '09s but they have changed their site making it harder to find anything if you ask me!!

I see what you mean about the Fusion but what does the knob really do? The '10 FEH lists a 6-way power, manual lumbar/recline but so does my '09 FE! All that means is that the seat's back reclines. I thought that you were refering to the inflatable type lumbar support.

With the addition of side airbags which are in the seats, that may have stopped the use of lumbar supports.
