B mode driving

[ndavey1]

Hi

I am a new owner of Jazz SR and absolutely love it. It’s my first hybrid and it’s such a great drive, not to mention the fuel economy!  I just wondered about the b mode.  Is it ok to drive in b mode on speed bump roads for example as I find the automatic braking useful, or should it only be used on downhill slopes? 

Also, can I switch between d and b mode while driving or do I have to be fully stopped with my foot on the brake?

Many thanks.

Nathan.

You can drive in B mode up to around 45 without any problem. Once you go above it will give you a warning on the speedo, also if you try to turn on the cruise control it will also give you a warning.

Yes, you can move between D and B whilst driving.

I've not explored the limits of B mode but my perception is that it makes more agressive use of the braking through regeneration when pressure on the accelerator is reduced than D. I find in D that accelerator position is almost an indicator of required speed which makes it easier to maintain the required speed on an undulating road. B is almost one pedal driving wherein lifting the accelerator applies the brakes.

I've found B mode great for around town, it's a nice level of speed reduction when approaching roundabouts for example. Sometimes I've driven almost entirely with one pedal in a town only trip.

I switch back to D when leaving town. The only other time I use it is on downhill slopes as you mentioned.

Returning to my theme on a similar post on this forum
Does driving in 'B' mode have the same effect, as changing down to a low gear, when descending steep hill?
I would normally use the paddles to drop down 2 sometimes 3 'gears' on my Mk3 CVT Jazz, in such situations.

Yep, exactly what I’ve been doing, b mode when driving on roads with speed humps, and when lots of mini roundabouts. Too much speeding up and slowing down required otherwise! 

Many thanks for all the replies.

I second that: it's my favourite driving mode in everyday town driving, basically going from on roundabout to another, and being overridden by e-bicyclists at traffic lights in between.

Cruise control can't be used in B mode though. Which figures.

Tried it out today - OK - felt comfortable. Used it most of time around local area - 45 mph roads and down - soon got the knack of judging when to take foot off throttle when approaching traffic lights - got it so well that most changed just as I approached them so was able to zoom off thru them. Did see no problems and it seemed as if the battery was charged better nearer to full capacity - it didn't seem to go out of EV mode so often - time will tell - but I am a convert at the moment.

You will also see a huge improvement in your Fuel Efficiency. Every time you brake you generate heat (as well as dust) which can only come from one source - the petrol you have just consumed.

Yes, as some of you have said it is just like changing down - say from 4th to 3rd or even 2nd on a manual car, but has the bonus of returning energy to the car and saving the brake pads

We only use 'B' mode. The only exception: when we want to use the ACC.

...You can use B all the time. There is no warning shown at any speed. You will feel greater brake retardation in B compared to D
You can just move the lever between B & D at anytime, no need to press any pedals or other buttons.
The only thing you can't do in B is use Active Cruise Control, you'll have to be in D for that.
You may find that there is a strange noise and a bit of a complaint from the car if you have a full battery and it is trying to charge it, just switch to D to stop that until the battery depletes slightly (probably within yards if you aren't going downhill )

The comment about 45mph isn't referring to B mode but the Lane Keep Assist which on the up to 2023 models will engage at 45mph (when switched on) but will still operate down to 40mph.

You will love the Crosstar. I have been driving it for two years now & the car is as smooth as the day I bought it.
