Thread: hill decent not working

You say appears ?
How have you tested to say it appears to not , Either it is or it is`nt .
Hill decent only works in low range

if you push the button while in high range, does it beep at you?

if not, look at the button

HDC seems to cut in at quite a high speed. Faster than I was happy with. I used engine braking, much slower.

IMO as long as the proper gear is selected HDC will work in addition to engine braking if you see what i mean.... it wont move faster with HDC than the engine lets it, so it can kick in or not the engine brake is the same,

insufficient to maintain a comfortable speed.......

In second gear I was at 10kph, too fast for the slope. In first gear, nice and gentle and the HDC did not kick in for either gear. I's always take a lower gear and go slooowly.

all those systems work off the same input,,

But traction control works via ABS...

Some answers to items previously mentioned may help to narrow it down....

But I do agree with Bohica, D2 HDC cuts in at a speed way to high for a serious steep hill. From memory I think you are be doing 7 km/hr before HDC cuts in... which in some places is twice the speed you want to be doing! I think it was improved in the D2 update....

Like any other ABS feature HDC will work well only with std dimension tyres, the bigger the tyres are the worst the system will work
