6 cyl to 4cyl ECO with 3.7L

My 2010 Liberty Renegade is equipped with the EVIC (Electronic Vehicle Info Center). One of the displays reads out the compass heading and outside temp. Below the temp, an ECO reading will be indicated when "you are driving in a fuel efficient manner". When I was test driving the vehicle the dealer told me that at this time the computer shuts down the fuel injectors to 2 cylinders to increase fuel milage. I have the ECO displayed after I have reached cruise speed, the tach indicates the torque converter has locked up, and I ease off the throttle to only maintain speed. Neither the Owners Manual that came in the glove compartment nor the 520 page expanded owners manual that I ordered (free) after delivery mention 6 to 4 cyl operation.

Does anyone know if this actually happens?

Also, I have read on this forum, I believe, that the injectors are deactivated when decelerating. Is this true, and if so, is it all 6 injectors?

Your salesmam doesnt have a clue what he's selling.The only vehicles that shut off cylinders are the Hemis,called MDS.Here is what the Liberty has- Chrysler has introduced iDFSO, Interactive Decel Fuel Shut-Off, software that cuts fuel to the engine while decelerating, to increase gas mileage. The amount of fuel shutoff is increased with certain engine speeds. This system increases both city and highway gas mileage, and lights a Fuel Saver indicator light when active.

Thank you for clarifying this for me. This point did not have anything to do with my purchase. But it does show that a lot of misinformation is thrown out in an attempt to make a sale.

I've been in sales before.

That's pretty much part of... selling. Lying. That's what they train you to do. Sad, really. I never lied. I used other methods to sell my products.

OT, where did you get the manual from? I think the move to disc is completely stupid.

I agree with stupid way to present detailed info. I tried to use the disc and wasted my time searching. I noted a phone number on the disc lable :1-(800) 992-1997 (in US). I called and got through to someone who mailed me the 520 page Owners Manual and also a Warranty Manual with very detailed warranty info, a must to understand ahead of time. The Owners Manual is very easy to use. Be sure to have your VIN number at hand.
