The 639s did not receive it until post-2014. Our 2014 Viano lacks that feature.
E classes possessed it during the same period that C classes lacked it. I am uncertain when C acquired it, but I suspect it would be the 204.
Certain individuals are unaware that they possess it. Upon purchasing the 2009 E, I stated my intention to evaluate the hold. The vendor enquired about its nature, and I demonstrated it to him (it was my initial usage, although I was familiar with it from this source). He subsequently aimed to evaluate his peer S for it.
Minor inconvenience, suitable for intermittent traffic conditions. Depress the brake more firmly to engage; as traffic progresses, apply the brake once more to disengage and advance slowly.
I do not observe any reference in the VIN decoding. I would search for it online; artificial intelligence can be quite precise, though not consistently.
