"apply brakes now"

[mcmaddy]

Boils my pi44 when people pull onto the opposite lane when cars are turning left. Patience is a virtue

I meant to say CanalMike....

Do you often seem to see a strange icon on your dash that is the one that means you are driving to close to the vehicle in front?

If you do, its probably linked...

[deltarikk]

Mine has come on just the once and it was whilst I was coming down Sutton Bank in North Yorks in rather exuberant style  ....rather twisty and quite a gradient, presume it saw the next bend (trees & hedge) looming large and was concerned I hadn't?! 

[fredgroves]

From the VW manual (tsk, who reads the manual eh?):

The area monitoring system (Front Assist) has physical and system-related limitations. The driver may therefore feel that, in certain circumstances, some reactions of the area monitoring system occur unexpectedly or with a delay. You should therefore always be prepared to take full control of the vehicle if necessary.

    In tight bends.

    If the accelerator is fully depressed.

    If the area monitoring system is switched off or faulty.

    If TCS is manually switched off.

    If the ESC is taking corrective action.

    If there is a fault in multiple brake lights on the vehicle or on a trailer with an electrical connection to the vehicle ⇒  .

    If the radar sensor is dirty or covered.

    If there are metal objects, e.g. tracks in the road or metal plates used in roadworks, or traffic signs above or next to the road.

    If the vehicle is reversing.

    Under hard acceleration.

    In snow or heavy rain.

    In case of narrow vehicles, e.g. motorbikes.

    If vehicles are travelling slightly to the left or right of your vehicle.

    If vehicles are crossing in front of your vehicle.

    If there is oncoming traffic.

    With pedestrians that are standing, approaching or moving in the direction of travel.

    In complex driving situations e.g. at traffic islands.

    In traffic situations that are unclear, e.g. vehicles ahead are heavily braking or turning off.

    When loads or attachment parts on other vehicles protrude to the side, rear or above the normal dimensions of the vehicle.

Switch off the area monitoring system:

    If the vehicle is being towed.

    If the vehicle is on a rolling road test bed.

    If the vehicle is driven in areas other than public roads.

    If the radar sensor is faulty.

    After external force on the radar sensor, e.g. after a rear-end collision.

    In the event of multiple unwanted interventions.

    If the radar sensor is covered temporarily by any auxiliary equipment, e.g. auxiliary headlights.

    If the vehicle is being loaded onto a truck, car ferry or motorail train.

Might've been easier for them to list when it will work

You should read the limitations on ACC:

When not to use Adaptive Cruise Control

    Driving in heavy rain, snow or when there are large amounts of spray

    Driving through tunnels

    Driving through roadworks

    Driving on winding roads, e.g. mountain roads

    Driving off-road

    Driving in multi-storey car parks

    Driving on roads with embedded metallic objects, e.g. train/tram tracks

    Driving on roads with loose chippings

    ​Vehicles without Inside Overtaking Prevention System: Driving on multi-lane roads if there are vehicles
    travelling more slowly in the fast lane.

Objects that cannot be detected

    Persons

    Animals

    Stationary vehicles

    Crossing and oncoming vehicles

    Other obstacles that do not move

For example, if a vehicle that has been detected by the Adaptive Cruise Control turns off the road or changes lane and there is stationary vehicle in front of this vehicle, the ACC will not react to the stationary vehicle

Bends

The radar sensor continuously measures straight ahead. This means that when travelling around tight bends, vehicles may be detected by mistake, or vehicles driving in front may not be recognised.

Vehicles outside the sensor range

    Vehicles that are outside the sensor range but travelling close to your own vehicle e.g. motorbikes

    Vehicles that move into your lane directly in front of your vehicle

    Vehicles with extensions or attachments that project above the vehicle.

You can get some interference from other parking sensors should they send a ping out at the same times. I've been sat behind a number of cars completely stationary in traffic and suddenly the parking sensors will start going mental for a second and then disappear. It's feasible that this is also happening when ACC is on.

F*$king hurts though when it pulls a full emergency brake routine out on you at random.

[Jeffers40]

This is probably the only feature of the car I don't like. The ACC is terrible on busy motorway and is constantly slowing me down. I've also had the apply brakes now flash at me a few times but the car broke for itself for the 1st time the other day and it was not good. Was driving enthusiastically on a country road and approaching a 90deg bend, I was already applying the brakes and was about to turn in with a little trail braking when it suddenly applied them harder for a split second.

Not sure how it can be a safety feature if it can pull off random emergency stops on you when it's fooled into it by other circumstances !!!

Love the ACC limitations list though, Driving in multi-story car parks  really 

[mcmaddy]

If your acc is slowing you down on motorways then you're too close to vehicles in front of you. It's exactly what this safety feature is supposed to do to stop you rear ending someone.

Really ? Mine reduces my speed way before getting close to other cars even when set to the lowest setting. It’s not like I’m about to drive into the back of someone !!!
