Question Help is needed with with Collision Prevention Assis Plus

Hello All,

I have a 2015 GLA250 4Matic USA Region. It does NOT have Distronic nor Lane Keeping Assist.

I have enabled Radar Sensor and Collision Prevention Assist in car's menu. But when I go to "Assistance Graphic" it shows "off" which is a sign for collision prevention being off! I read the manual. I am not sure if I am missing something or anything might be broken!

I attached a snapshot that shows snippets from manual and 3 snapshots from car's menu.

Would you please let me know what might be wrong?
BTW, I left the menu at "Assistance Graphic" and drove for 10 minutes; still it was showing "off"; so being in park should not be the issue!

Thanks,

Welcome to the GLA forum. IIRC, Collision Prevention System Assist Plus is part of the Distronic system. However, if I'm not mistaken there is still a standard collision prevention system operating, which is what might be confusing. Guessing the Plus system doesn't activate because you have don't have Distronic.

MB seems to do that with other things. For example, my early 2016 production model (September 2015) has the menu options and jacks to activate Apple CarPlay and Android Auto, yet the wiring and connectivity for it wasn't available until production after 1 December 2015 as a special order option.

Recommend you verify with a MB service facility to be sure. Otherwise, there's probably an issue that needs attention. Please let us know what you learn.

Thank you Turbolink for the reply.
I will take it to a MB shop and have them check it out. I will post the results here. Meanwhile, if someone else has a different idea/clue, please let me know.

Peace ✌

The third screen "Assistance Graphic" is for cars with Distronic where they can set the distance to follow another car. MB in this case has only one display to do all, in place of multi displays systems for only what is on a car.

Thanks for the reply 👍.
Does this mean that my car has the "Collision Prevention Assist Plus" or as turbolink said, it only comes with Distronic?

Plus only comes with Distronic. To find out how your GLA is equipped, you can look up the original equipment detail from any of the free online VIN decoders.

I believe all GLAs have Collison Assist as standard equipment. I say believe since I can't vouch for all platforms I all countries ... But Collision Assist is an entirely independent system from Distronic.

Like Wayne says all GLA comes with COLLISION PREVENTION ASSIST to the best of our knowledge in the USA/ This detects you are about to run into something in front of you. If it detects that you are taking action on your own it will not do anything. This means you do not change your speed, apply brakes or turn to avoid a hit it stops your car. MY salesman said in demo training they set up a wall of foam blocks and when a person did something like slowing down or touching the brakes they ran into the wall, he closed his eyes and kept driving toward the wall and the car stop. There will be a light flash on the dash and a beep will be a warning.

If on a divide road with a grass divider and a car turns into a cross over in front of you you can get a warning or if the is a deep dip in the road could get you a warning.

The thing I hate about this feature is that it doesn't give any feedback about how it's working, or even IF it's working. I realize it's a last resort failsafe, but I currently have ZERO faith in it.

Ours has beeped at me multiple times driving in traffic but has never activated. I figure it's nice to have but I would never depend on it.
