The regulation is clear about a chime every two minutes when above 80 KMPH and below 120 KMPH. I think most people won't notice it. I also noticed it only after driving my car for nearly 30,000 KMs and in conversation with a Mercedes representative. I could be wrong though. Let me know if you or any other member here is able to verify this behavior. I'd love to get it out!

2.1 The audible warning shall warn the driver with frequency not less than 1 cycle/ 2 minute when vehicle speed indicated in the speedometer exceeds 80 km/h (primary level) and continuously or intermittently with frequency not less than 1 cycle/ 2 sec when the vehicle speed indicated in the speedometer exceeds 120 km/h (secondary level).

Haha, now you’ve piqued my curiosity. Will definitely check for this the next time I drive the car on Atal Setu or Pune Expressway. You can get an easy 2 mins plus at 100 kmph on Atal Setu for sure.

On a separate note, has anyone managed to get their info cluster to display tyre pressure in PSI instead of KPA?

No luck on the tyre pressure thing. It is in Kpa in all Mercedes vehicles. I had a C Class prior to this where I tried all possible options including peeking through options on their software in the Service Center when it was connected for updates and checks. They too tried but could not find any options to change it. (The MB Mercedes Me app on the phone shows in psi though)

The only option is to go and edit the Hex code sets as we used to do in Ford Endeavour using Forscan but for that we need to know the right codes and the right equivalent software like Forscan for Mercedes. The Service Center dashboards have no options just like the Ford ASC software had no options.

Another thing I have noticed is that even some of the smarter and knowledgeable technicians have little understanding of things beyond what Mercedes "trains" them for. I spent a couple of hours with a senior technician looking for new Fuse Box diagrams and Fuse allocations and came up with zilch. This was to connect a Dual Channel dashcam to the new GLC (MB does not have the dashcam for GLC any more till an updated version is released next year and they do not commit any date for availability either). Given the number of Road Rage cases in Bangalore lately, it is important we have a dash cam for our own security.

Then I did some research on the web and on MB Forums and, voila, I found the entire Fuse allocation chart neatly folded in the Boot Fuse box compartment of my own car. Apparently this is mandatorily included in all cars as per EU and US laws and none of the local folks were even aware of it.

Attached couple of pics of the folded and opened chart which was in the boot fuse box. (That is an A3 sheet)

I managed to connect the VIOFO A229 Pro Dual Channel neatly after that.

Yeah that’s what I’ve gathered too.

That’s disappointing to hear but somehow I’m not surprised.

This is my feeling as well (that a dash cam is essential nowadays). I have been following up with Mercedes dealers here and I’m told they’re in the thick of some paperwork on this and it should be available in the next month or so. Its expensive as stink to go Mercedes OEM but I’m just too reluctant to go with an aftermarket and risk warranty. Want to bite the bullet and pick the Mercedes one if it comes back on sale in India.

Thanks for sharing and updating on this.

Two points:

1. Warranty should not be an issue if you seek guidance from MB Service folks on the right fuse to tap. They are quite supportive knowing the importance of Dashcam in today's situation across Indian roads. I got the same done even in my C Class a few years back and they only helped me find the right fuses to tap so that it has no effect on other electricals.

Even if the specific ASC/Dealer is being difficult, the same can be easily challenged i.e. if it comes to that. Any automobile electrical engineer can articulate how a low wattage device wired correctly using right taps or spare fuse slots can not impact other circuits or the battery (if ever it goes legal).

2. MB Dashcam has inherent flaws compared to some of the newer models in the market. The ones I am aware of are (a) limited size storage support - currently 32 GB (b) unable to display both front and rear on the same screen on any connected wi-fi device (c) inability to connect 3rd car interior channel if so needed

Last but not the least, it costs more than twice of the some of the best advanced dashcams in the market.

My only recommendation is to not use Parking mode regularly (unless absolutely necessary for short periods when you park in unknown places) to avoid battery drain. Also set the auto cut-off on the connecter voltage regulator to 12.2V or 12.4V so it can never affect the battery. It will switch off the dashcam when it senses battery below that voltage.

I would suggest you talk to them and if you have a good relationship with the ASC, they should be supportive. MB Service and Customer support is extremely helpful and very supportive. The very reason I got second car from them.

I have been using a 512 GB SD Card [Amazon Link] without issues for a couple years now. There are times when the camera somehow starts rotating videos as if the card was only 256 GB but even that is plenty compared to the default 32 GB card provided with it. I have a single channel front only Mercedes Dashcam installed sometime in 2022. It was a the last of the lot I think. Mercedes stopped selling it afterwards.

I have a dual channel Mercedez Benz Dashcam installed in my GLC, though initially they said it was not available, suddenly it became available for a few weeks. As Naresh mentioned, a dashcam is an absolute necessity nowadays; in fact in the UK, GLC is enabled to connect to an external device to download the front camera views. Another drawback of the MB dashcam is that it shuts down if the car is parked in direct sunlight for a while and will not restart until the interior cools.

Btw. I was on a 600+ KM drive this weekend, it is clear that the continuous audible chime only happens after crossing 120 KMPH. Most of the time I drove about 100 KMPH on the BLR/Salem/Theni highway.

I have a quick question about how long we can keep the car parked without putting it on standby.

The reason I ask is that I normally use the car for out-of-town drives only; Otherwise, I take it for a short drive once a week. Is this ok? Or must we start or drive the car more frequently? Considering all the electronics that are active while in parking mode. Is anyone keeping the car parked for a week or longer regularly?

Thanks.

My 2022 GLC 220D has moved a total of 900kms in last six months with a total ignition on time of 34 hours, staying idle for weeks at a time. I have not noticed anything troublesome so far. Not an advice, just sharing an observation.

[sknair]

Quick update: After all the software updates, I have left the car parked for more than two weeks at a stretch a few times now, and so far, there have been no low battery warnings. The latest door control module updates seem to have solved the problem.

Guys

Sorry for the basic question. Can someone please explain how the 4matic system works on the 2024 GLC 300?

Thanks in advance.

From the MB website, this appears to be a permanent 4x4 All wheel drive.

There are three Mercedes-Benz 4MATIC AWD systems that can appear on Mercedes-Benz models. Take a moment to explore the differences between these three systems:

Permanent 4MATIC All-wheel Drive: This system can be found on the Mercedes-Benz GLC SUV, Mercedes-Benz C-Class, and other models. It continuously supplies all four of your wheels with a steady, evenly divided stream of torque for consistently superior handling.

Variable 4MATIC All-wheel Drive: This system can be found on the Mercedes-Benz GLA SUV, CLA coupe, and E-Class. It shifts between FWD and AWD as needed, allowing you to reap the benefits of AWD on slippery roads and the efficiency of FWD on more tractable terrain.

4MATIC All-wheel Drive: This system intelligently monitors your wheels for slippage and sends torque to your wheels as needed, which allows for the consistently sharper handling of permanent 4MATIC AWD, with the better efficiency of variable 4MATIC AWD.

Not sure where I read or saw it but I believe GLC 4Matics are equipped with a simpler permanent 4x4 with 60-40 split between front and rear axle. I think there's not much intelligence under the hood as to which wheel needs more or less torque.

I had sent my 2024 GLC for free inspection today (3 months from the purchase). The service advisor has informed me that the rear shock absorbers are not functioning well (though I haven't faced any issue) and that they will be replaced free of cost under warranty.

Has anyone else faced this issue?

Also, on dash cam, I have been quoted Rs.65000 (with labour) and it will require 2 days for the installation.

Got the GLC300 fairly recently and have been loving everything about it. I have a question regarding upshift and downshift to and from D3 and D4. Has anyone noticed a shifting sound (really mild one) coming from the transmission tunnel at the back of the vehicle? I asked the SA and she mentioned that it is common in this segment but I wanted to double check with the actual experts here.
