On my 2011 Equinox, The high beam headlights are activated by pushing the lever forward. So far so good, but to turn them off, I have to push FORWARD again.
According to my manual
Push the run/lane change lever away from you to turn the high beams on.
Pull the lever toward you to return to low beams.
The Push-Push I'm seeing on my vehicle is unlike most other cars on the road - I drive lots of rentals. The first time I tried this, I was on the road, and luckily figured it out before blinding the oncoming driver. Which is correct - the way it actually is working, or as described in the manual? Everything feels correct, and not like there is a malfunction.
