Re: Cylinder deactivation mode

...all your horsepower goes away...?

I would assume some kind of light will come on...I'd check the owner's manual to find out what it is.

I have a 2015 with the V8 - there is no indicator to tell you when cylinder deactivation has happened.

Re: Cylinder deactivation mode

It just does. There is no way to really tell on the 2014+ models without an aftermarket exhaust or programmer/scanner. Even with ECO mode off, it still does it, just not as aggressively.

Too bad there is no indicator that pops up in the dash when enabled.

That looks like a lot of work! I guess I'll just pay attention to the rpms and the sound of the engine

Re: Cylinder deactivation mode

my 2012 has an ECO light that shows up in the Evic when it trips into 4cyl mode. You can hear the difference in the engine.

Re: Cylinder deactivation mode

Why would you want an indicator?
