I get a warning that Pre-Collision assist won't work because the Radar Sensor is obstructed on frosty mornings.

I'm not clear on where the sensor is. The owners manual shows a camera in the windshield and an OPTIONAL radar sensor in the front end. Being that my car is a base I was presuming to not have such an option...

Has anyone else had this happen yet? How does one go about resolving the issue? Wipe off the front grille and windshield before I roll out for the morning?

I've also seen on other forums where cruise control may not work with the sensor obstructed. I'm not going to be using cruise in the rain or the snow, and thankfully my commute doesn't involve highway driving, but some of my planned mountainous excursions might be affected by such a stupid constraint...

yes mother nature can be a “stupid constraint.” It’s important people don’t become dependent these assisting safety systems. In times where weather and bad road conditions it’s important to drive with extra care (the original “pre collision assist).

if you have reflexes on the slower side, and you wouldn’t be able to stop or avoid the car in front of you if they were to slam on the brakes.. back off a little.

For your specific issue of off highway driving in mountainous excursions.. if you are afraid of colliding into another object without the assistance of pre collision assist.. should you really be driving?

It’s like gun safety. Even though you know your gun is either empty or the safety is on, you still act like it’s loaded at all times and that the safety will fail by never pointing it at anyone that you don’t intend to hurt. You should always drive your vehicle like it has no safety features or assistance even if you have the most safety equipped vehicle. Ok lesson over.

Here is a list of actions to resolve the issue you have straight from the owners manual.

I'm sorry if my point was unclear;

I wish the car didn't HAVE pre-collision assist. I bought a Base model to avoid as much 'tech' as possible. I've disabled lane-keeping and diligently turn off Auto Start Stop, but I'm stuck with this, at least at the lowest sensitivity.

When I said I didn't want my access to cruise control hampered the point I was trying to make was that if I wake up in the cold and l need to hit the highway I don't particularly like the idea of not having access to cruise control until the error clears itself out.

Also, I noticed the entry in the manual, and I referenced it in the OP... my question should've been 'does the base model have the radar sensor?'

the manual says that you can turn it pre-collision off. You should not be “stuck” with this and I hope you are wrong because I am the same I do not want any of that tech turned on.

Are you referring to basic cruise control or adaptive or intelligent cruise control. Adaptive cruise control works with the same concept as the pre collision assist where the radar and camera needs to be unobstructed. Note the fact that adaptive cruise control slows the car down and adapts your speed due to the car in front of you. If neither you using your foot or the system not able to use the sensors, the vehicle will not be able to stop from collisions. One of you need to drive the car. I suggest if you must use cruise control, you use basic cruise control and adjust speed when necessary and turn those systems off that require unobstructed sensors especially if you want to “avoid as much tech as possible.”

I see that, but the question is whether or not the radar sensor, listed in the owner's manual as "optional" exists on the Base model. I don't like out-of-context quotes from unverifiable sources, but I found this on the Ranger 5g forum:

edit: just found this in the Owners Manual, suggesting that the Radar Sensor is only included with ACC, and ACC is only an option on Big Bend and above.

Right above the previous owners manual info:

Sounds like you can turn the sensitivity down and the setting is remembered, but you have to go in and disable active braking every time you start the car, and it's not as simple as the conveniently placed Start Stop button.

I should've screenshot the similar post I found (which inspired my creation of this post,) but the only post I can find at this point referencing the regular cruise being linked to the assist is:

Edit: here's another. Obviously second hand info but curiousity provoking:

if that’s true, hopefully the lowest setting is unintrusive. Can you show the process of manually disabling AdvanceTrac. Once disabled, surely you‘ll be able to use normal cruise control when sensor is obstructed. Not that I’m interested in using cruise control but understand you and others are.

I'll see what I can figure out about AdvanceTrac; don't see anything about how to disable it in the manual, so I'll have to get my hands dirty and click some screens, haha.

All in all I love this little car, but man oh man do I long for the days when the most annoying thing about newfangled safety features was getting used to the brake pedal pumping back at you with ABS.

I completely agree with you on that. Wish I could get my hands dirty. All I have is the owners manual to learn about it. Cant find it either. I ordered a paper copy. Tired of scrolling back and forth

It sounds like AdvanceTrac is just a fancy term for Ford's combination Traction control and rollover avoidance control, and that it comes on just like everything else, every time you start the car.

To disable 'AdvanceTrac' is to disable the entirety of the TCS, and I'm not sure I want to do that by default.

As for how to, though, I'll fiddle with it tonight once I'm home and post some photos.

I turned mine off in vehicle/settings on the infotainment screen. No drama no problem, it was simple.
Turned it back on at the softest setting after we warmed up a bit and the snow stopped.
Base model here......

Check it again... It should turn back on every time you start the car, just like the Auto Start/Stop.

True, after I turned it off that one time and back on when I got to town I realized It's simpler to Ignore it all together now that I know It was Ice/snow that caused it. Not much winter here so It's a non Issue for me.
