How do I keep the motor running?

Asked by Jun 05, 2017 at 08:26 AM about the 2009 Mercury Mariner Hybrid Base

Question type: Maintenance & Repair

So I got an 09 mercury mariner hybrid and it's just
miserable in the heat in town because it goes into
EV mode so often and shuts off the ac. Does fine
on the freeway when the motor stays on.
I heard that unless the econ button is pressed that
it's supposed to keep the motor running until the
desired cabin temp is reached and only then allow
it to go into EV. Mine does not do that. It seems
like the econ button is stuck on or something as
actually pressing econ has no apparent effect on
anything. What should i try to fix this issue? I can't
take sweating in stop and go traffic anymore.

Being green sucks! I would talk to your local Ford/Mercury dealer to find out what the proper operating mode is.
