Beep sound for B Mode?

Do not use B mode for routine driving (ie, level roads, normal stop and go). There is NO need to use B mode for 'sparing the brakes'. It is used for regenerative braking on long down grades. The actual disc brakes are only (only) applied on your Prius when you are at 7 mph or below or when applying brakes HARD for an emergency stop, thus, Prius brakes (discs and pads) routinely last for 100,000 miles or more. Under normal stop and go conditions, when you apply the brake pedal, regenerative braking comes into play, and the disc brakes are not even applied. Have you read your owner's manual? Highly recommended...

 

no, there is no beep, or (known) way to make it beep. agree with ed^^^ no need for b mode to slow down, just use the brakes early and gently.
i try to anticipate stops by letting off the gas (regen) and using the brakes as little as possible (more regen)

 

I experimented with B mode when I first got my Prius. But the more I learned about how the car worked, the less I had a good reason to use it...

 

its only for long steep downhill grades

 

It is there by federal law, useful or not. A 'downshift' gear is required, this is the closest a Prius could do.

 

I do not have a literal beep for B mode, but you can't engage cruise control in B mode.
For some one who spends 95% of the time with CC engaged, it is a tip off.

 

That doesn't logically follow at all.

Long downhills are the intended use. But even in flatland markets where it is totally useless, federal law still requires it to be present.

But only 75k on factory Prius brakes? Something is amiss here, many PC members get double that. Absent winter road salt corrosion problems, both the spouse and I got 100k on the original brakes of our traditional non-hybrids.

While it makes no sense when accelerating, it also hurts nothing, not even fuel efficiency. Not a problem.

The only downsides of unnecessary B use are loss of efficiency (lost energy harvest) on downgrades shorter than when it is needed, and loss of ICE auto-stop (unnecessary engine idling). When accelerating, or when running steady speeds where the ICE must be on, it does nothing more than lock out cruise control. No harm, not foul.

 

That's a bit of manual editing. The best way I found is to quote the original, then insert a quote-close BBcode tag at the point where you wish to "interrupt" for an inline reply.

Then open a new, unattributed quote and paste the remainder of the original post between that and a final quote-close tag.

Example:

Code:

[QUOTE="PriusOnTheFence, post: 2970199, member: 56983"]But if you could tell me what the code is[/QUOTE]

:whistle: Little bunny foo-foo :whistle:

[quote]so that I can insert responses within someone's quote, that would be very helpful![/QUOTE]

renders as:

Little bunny foo-foo

 

Maybe highway vs city driving? Our driving is mostly local; and extrapolating from previous checks, the latest I'd expect to be changing is around 100K miles. This is extrapolating from my previous inspection, at 66K kms, where I found pad depth around 7 mm (3.0 mm's of wear).

Also considering minimum usable pad depth of 2mm, not Toyota spec 1mm. Really: if I opened them up and measured even 3 mm, I'd be inclined to replace anyway.

The two bottom values are useful too I think. Again, our usage is mostly urban, not a lot of easy rolling highway driving.



Addendum: I had in my head that new front pad thickness was 10.5 mm. It is in fact 10.0 mm. Screen grab from spreadsheet reposted, and minor edit to the text, to suit.

no beef with b mode, more power to you

 

You very much misunderstand B mode. It does none of that. There are no simultaneous contrary forces applied to the engine.

(FWIW, plenty of us on this forum are engineers.)
