2023 MB GLA 250 with Nav and every option available except HeadsUp display (apparently only AMG mod gets this option).

Giving my two cents to MB hoping they read this and learn.

Why would a car like mine that cost $49.5K before taxes not have an audible alarm when backing up and
an object (car, person, baby carriage, etc.) is likely to be struck?? Let alone one that would not automatically brake to
avoid contact?

Fortunately for me, it was only a shopping cart I hit that cracked the rear tail light housing.

MB you should be ashamed to make a car with just a backup camera as your only safety feature in this day and age.

Does this car have ultrasonic obstacle detection sensors (small round circles in the front and rear bumpers)?

JayJayEff

No. I guess that should have been something I looked for before buying this car.

I’m not going to wade through that option list, but if you have everything then you have the 360 degree camera. Something is not working. The cars with 360 all have automatic braking. All the GLA models have forward collision warning and automatic braking standard, but 360 degree is an option. The FCW is sensitive to the point of being aggravating.

That being said, something like an empty shopping buggy might not be detected because it’s not very solid. My daughter’s MB (not a GLA/B) brakes automatically when anything enters the 360 preset distance. My wife’s GLB brakes automatically when the neighbor’s Yorkie walks behind it. I had a GLA250 rental that jerked me to a stop backing out of a parking spot when a car crossed behind.

Serhan

It doesn't look like you have the parking sensors that usually comes with the parking assist system... My GLK didn't have the parking sensors, so I was specifically looking for the parking sensors when I was buying the GLB. My GLB came with the parking assist that has the parking sensors and 360 camera, not with the driver's assist option. New generation GLC300 that I had as a loaner has the 360 camera+sensors with the active collision warning while even it is in parking mode.

GLB sensors beeps for everything eg a stone/barriers/bushes/stationary cars, etc close to the car and auto-breaks for any approaching pedestrians and cars both from front and rear of the car even before I see them. Parking assist has similar auto break function to driver's assist system as below eg breaks for crossing vehicles, pedestrians in rear. I don't know if it auto breaks to a shopping cart or stationary object as the hard breaks might be for pedestrians, cars, cyclists..







Also there is Drive Away Assists when I start the car or the Parking Assist is activated. Drive Away Asist with 360 cameras does not work above 5 mph speeds.

No system is fail safe yet unless you get a MB with self driving option with level 3 autonomy:

JayJayEff

Thanks for the info OP. I HAVE experienced the automatic braking when driving and the car senses I am drifting
over the lane markers. But as for backing up, other than the cart, I get no beep or buzz if a car is passing behind.

JayJayEff

The parking assist may well be the thing that is missing. The options only show "Active Steering Assist".
My other vehicle is a Jeep Cherokee that has the automatic parking and it
beeps whenever a object (vehicle, person, etc.) is close. Plus, there are settings for the range of the proximity sensors in the menus.

Serhan

GLA/GLB parking assistant comes with 12 sensors around the car to detect any obstacles:

Read the 2023 GLA manual on mbusa. What does it say about parking assist?

gmanz e500

To OP;
it was difficult to wade through all of those options, however if ' 501 ' is not there, you do not have the 360 degree camera.
if the camera is required [I'm not sure if that is a fact], then you do not have the active braking.

JayJayEff

No, I do not have option 501. I do have the Driving Assistance Package which I paid extra for and it includes:

Mercedes-Benz Driver Assistance Package Features:

• Active Distance Assist DISTRONIC®: Keeps you moving at a set speed, and adjusts your speed in response to the presence of other drivers
• Active Steering Assist: Keeps you centered in your lane at all times
• Evasive Steering Assist: Executes more controlled emergency maneuvers when you take evasive action
• Active Brake Assist with Cross-Traffic Function: Detects potential collisions and adjusts your braking pressure accordingly
• Active Emergency Stop Assist: Automatically slows and stops your vehicle if an imminent collision is likely to occur
• Active Speed Limit Assist: Automatically detects changes in the speed limit and adjusts your set speed accordingly
• Active Lane Keeping Assist: Returns you to the center of your lane if you cross over a road line
• Active Blind Spot Assist: Returns you to the center of your lane if you start to move while another vehicle is in your blind spot
• Active Lane Change Assist: Automatically transfers you to the lane of your choice when you leave the turn signal active for several seconds
• PRESAFE® PLUS: Closes the windows and adjusts settings in order to minimize the threat of a collision
• PRESAFE® Sound: Emits a sonic tone that protects the ears from damage in a collision
• Route-based Speed Adaptation

Lots of inaccurate posts on this thread.

Active braking and active emergency stop are used when the vehicle is driving at speed, and are not the same as parking assist at near-zero vehicle speed.

If @JayJayEff 's car does not have ultrasonic sensors in the bumpers, it will not detect a shopping cart.

The GLA is an economy car and MB has chosen to offer a not-fully-equipped base model. The parking assist option was not chosen by whoever ordered the vehicle.

Serhan

Part of Parking Assist / PARKTRONIC system is Function of Cross Traffic Alert:
Vehicles with Blind Spot Assist or Active Blind Spot Assist: Cross Traffic Alert can warn drivers of any crossing traffic when backing up and maneuvering out of a parking space. The radar sensors in the bumper also monitor the area adjacent to the vehicle. If a critical situation is detected, the symbol appears in the media display. If the driver does not respond to the warning, the vehicle's brakes can be applied automatically.

Blind Spot Assist and Active Blind Spot Assist use two lateral, rear-facing radar sensors to monitor the area up to 130 ft (40 m) behind and 10 ft (3 m) next to your vehicle.

I had several hard breaks when a crossing car in the rear is approaching from 100' away while backing out between 2 cars... 360 camera is not detailed for that far and car applies the hard break like you hit something... The rear cross traffic alert functions same as the front cross traffic hard/emergency break...

superswiss

Your car is missing the Parking Assistance Package, which is why you don't have the parking sensors. That system is called PARKTRONIC and it's part of the Parking Assistance Package, even though it's not specifically called out in the order guide. A basic backup camera is mandatory now in the USA, which is why you only have that. There are no parking sensors or any other parking assistance features, unless you option the Parking Assistance Package. This package will also add the 360 camera and the Active Parking Assist, with which the car can park itself.

Odd Piggy

Good points. The active brake assist shuts off at about 4 MPH. I haven’t researched the 360 camera option in detail, but every one I’ve driven won’t go anywhere if it detects anything with the camera in that preset distance. That Yorkie has stopped us from backing out of the driveway many times.

The GT43, which lives somewhere between E and S and has every option known to the gods, won’t even let me pull into a tight parking spot. But I wouldn’t expect that performance from A and B cars.

As for the OP’s complaint, I would have to place at least some of the blame on the dealer for not fully explaining what functions were or weren’t included in the option list. That’s especially important for a buyer coming from a domestic. One of the big surprises is that garage door openers are optional on MBs.

JayJayEff

So, by all the information in the post's you guys have made, I am missing the parking assist feature. Being that I specifically asked the dealer to include all the safety feature options, and
besides not doing my own research, this is the result.

I want to thank all of you for the education and appreciate all the help you have given. I will probably look to replace this vehicle in the near future for reasons other than the missing options
anyway, so thanks again and consider this thread answered.

OldManAndHisCar

I read post #1 and thing - Okay, this idiot millennial does not belong on the roads....YOU are supposed to drive the car, not the car.

OldManAndHisCar

Odd Piggy - on my E63S with 360 it does NOT hit the brakes, just tells me something is there. Then again, I pay attention and dont count on technology to drive.....

Odd Piggy

Curious about that. What year is the E63S? The GT43 is built on an E chassis and I would have thought the system would be identical.

When something is in the 360 cam “danger zone” it doesn’t slam on the brakes like the collision warning does. It just won’t let you go anywhere. I didn’t even see the Yorkie the first time it happened. I got out of the GLB to try to figure out what was wrong.

I’m with you on the technology point. The owner’s manual makes the note that it’s just there to assist. My GLA base model has none of the optional stuff, just the standard backup cam, FCW, blind spot warning. Backup cam is nice, the other two are aggravating. Just don’t be too hard on the OP, he probably grew up surrounded by technology.

superswiss

I do unfortunately agree. Today's younger drivers don't know what they are doing. I've driven most of the 25+ years w/o parking assistance systems and have never run over a shopping cart or similar. I will say this, though. Part of the problem are the ever larger vehicles. With SUVs in particular, you can't really see what's behind you, which has lead to the mandatory backup camera in the USA, because too many people have run over small children they couldn't see. Although, the GLA is not particularly large, it is higher up off the ground than a typical hatchback.

OldManAndHisCar

I am just 50...I learned to drive in a Jaguar XJS V12 Convert. (1989????)...that car was about 15' long. We had station wagons (equally as long), Suburbans, Jimmy and on and on. Not until the "Gas Crisis" did the smaller cars hit the scene. The K car, Omni, Pinto and on and on and on....they were driving blind spots. No seat belts, no air bags, and DUAL cigarette lighters! Oddly, we made it. The OP on the other hand is disappointed by the lowest model car made by MB because its robots did not protect him from him. IMO, the only reason this car was purchased is that so the MB logo could be in a few selfies.....

OldManAndHisCar

We shall email a trophy ;-)

And no, we NEED to be hard on these folks......

Odd Piggy

Guess I am getting soft in my old age. 😉 Vid reminds me of why I like Australia so much. Reminds me of the ‘50s US. There’s something to be said for selfies with the tri-star. At 1.8% of US sales it must be exclusive, right? And how about learning to drive on a ‘53 Plymouth Cranbrook Coupe? Its high tech features were a 3 on the tree and turn signals. My first ride was a ‘64 Olds 88. It had a helm instead of a steering wheel. 😉again!

I'm curious to understand why looking at your back up camera screen is too difficult for you? I have no problem looking at my back up camera screen when driving my daily driver to make sure that it's safe for me to back out of a parking space, etc. all of the time. I don't need an additional alarm to tell me when it's safe to back up because I can see with my eyes. My MB is old enough that it doesn't even have a back up camera. I guess driving older cars won't be an option for you. To be honest I find your complaint about not having an alarm in addition to your back up camera with a screen that you can actually look at with your eyes to be totally ridiculous.
