2015 Nissan Murano: Decent Adaptive Cruise, But Could Be Better
May 7, 2015
As something of a persnickety cruise control-er, I made a few notes about the Murano's cruise control system, which does some things very well, but has room for improvement.
The Murano's cruise control is adaptive, and in this capacity it works pretty well. It always correctly discerned between vehicles that weren't actually in my lane and those that were. No false positives. Not once was it tricked by curves in the road, which is not something that all systems can claim. Pretty solid showing here.
It also does its slowing, like when approaching a slower vehicle, with minimal abruptness. It sheds speed smoothly and without drama. Like all adaptive cruise control systems, the Murano's following distance is more conservative than I'd prefer, which also means that it begins slowing sooner than I'd prefer. I get it — lawyers, after all — but it doesn't mean I have to like it.
Where it could improve is on 'Resume.' The Murano takes its sweet time initiating the Resume process after a slower car finally moves (completely) out of the lane, and then the actual resuming occurs too leisurely at freeway speeds. I found myself adding throttle manually to speed things along, which revealed another quirk of the Murano's cruise.
Rather than my throttle input supplementing the car's built-in rate of resuming (which is the way it works in most cars I can think of), it appeared to override it. Meaning the car ceased its own resuming activities when it saw my throttle input.
I discovered this thusly. When my desired set speed was looming, I'd lift and let the car, which really ought to have been contributing its baseline amount of throttle this whole time, take care of the rest. The car however, having paused its Resume process, would then be caught unawares and fall on its face momentarily until it realized what was going on and could re-initiate the resuming process for the last few remaining mph.
It's just kind of sloppy calibration, that's all, but these are the things you fixate on during a long, dull drive up Interstate 5.
No adaptive cruise works ideally for all drivers in all conditions, which is why all adaptive cruise control systems should (and often do) enable you to revert to conventional cruise. The Murano's system unfortunately doesn't. It's adaptive cruise or none at all. Well, poop. Adaptive cruise is part of the Murano's optional Technology Package, something to be aware of if you're a cruise nerd.
