cruise control

Cruise control (also known as speed control, cruise command, autocruise, or tempomat) is a system that automatically controls the speed of an automobile. The system is a servomechanism that takes over the throttle of the car to maintain a steady speed as set by the driver.

    Adaptive Cruise Control - Braking either on or off?

    I've rarely had the opportunity (or motivation) to use ACC but a recent longish trip on fairly fast straightish highways seemed like a good time to try it again. Sadly, despite an OTA firmware update and a 20,000 km service earlier this year I found that it seems incapable of the kind of...

    Combining dynamic cruise control and traffic sign recognition

    I think it would be a game changer for MG if the Dynamic Cruise Control (DCC) and Traffic Sign Recognition (TSR) systems worked together to automatically adjust speed in response to changing traffic signs. Integrating these two systems would significantly enhance driver convenience and safety...

    Cruise control

    Can anyone explain, in simple terms, how to operate adaptive cruise control. I know what it does, but the actual operation as explained in the manual is very long-winded. By the time I get to another section I've forgotten the first.

    Active cruise control not that good

    I tried it out yesterday for the first time on 50 limit dual carriageway, it was fine and adjusted it's speed well, I did get a bit nervous when we came to the island at the end and had the brake covered but it slowed down well enough, the next bit was a 40 limit so I left it to fend for itself...

    Cruise Control Steering Wheel Stiff

    Hi, I searched in the forum and couldn't find the answer to this. For mg MG4 Trophy EV, the steering wheel appears stiff when on Adaptive Cruise Control. What I mean by stiff is if you're trying to re-align the car in the lane and move the steering wheel slightly, the steering wheel is very...

    Adaptive Cruise Control issues after update

    Several software updates were performed during my MG4 SE LR first service in April. I now notice that the ACC function is behaving differently. It appears as if switching on ACC is now also enabling LKA, with the associated unpleasant steering nudges. Anyone else seeing this? One of my...

    Loss of cruise control and collision warning

    When travelling to Edinburgh on the M90 near the turn off for Kinross B977 I lose my cruise control and collision warning. This has happened on the last 6 journeys whether travelling north or south. The car resets itself after about 2mls. The loss seems to coincide with passing a phone /...

    Cruise Control not disengaging

    On 3 occasions now, I've nudged the Cruise Control lever forward, the way I tend to disengage ACC, but it's taken up to 10 seconds before it's actually disengaged! By that I mean the car carries on at the speed set (70mph), without slowing down, despite going slightly up hill. Also, the...

    Cruise Control Not Working

    First motorway trip in the new car and I always use cruise control through the many 50mph zones. However nothing happened when I pressed the button on the steering wheel. Would this be related to my start-up habit of deactivating ELK & FCA? I tried turning them back on (whilst driving) but...

    Cruise Control Issue

    So I recently got a zs ev and have notices that when cruise contol is on and I am driving on a flat road that my car will start driving above the set cruise control limit. This has gotten me a speeding ticket the other day and I'm pretty ticked off at it. Has anyone else had this issue or knows...

    Adaptive Cruise Control

    Does anyone know when using ACC whether the brake lights come on when ACC brakes due to slow/stationary traffic please? I want to know if someone following me gets a warning of rapid deceleration. Thank you.

    Traffic Jam Assist

    We drove from a bit North of Sydney to West of Brisbane (circa 1000 km). We encountered two significant traffic jams on the motorway outside of Brisbane. I set the cruise control to the posted speed limit. The traffic jam assist was terrific! It made the stop and go driving much less...

    Adaptive cruise control ACC

    I've noticed if I drive on motorway at 70 mph and use the ACC and then use the brake to slow down, the battery will shut down. I recieve a fault and need to pull over. Shut the car down and restart and it works again. Is this a common fault or is there something I'm doing wrong?

    Settings To Get Just Cruise Control Functionality?

    Took my 4 onto the motorway for the first time and I’m used to just pressing CC and then holding that speed. But with the 4, it was trying to steer for me (causing a vibration effect through the wheel) as as well constantly doing minute alterations. Then the lane keep assist was beeping and...

    ACC without the A

    Does anyone know if it is possible to disable the Adaptive facility of the Cruise Control? Why would I want to do that you may ask. Well, living in rural Wales we now have a 20mph speed limit around town and speaking to a delivery driver he just uses his cruise control to keep within the speed...

    Fuel consumption on cruise control

    I just went on a long trip from Paris to London and back. On the motorways, I was setting the car on cruise control a lot, and I noticed that when it would slow down, the display which shows power would never go below 0%. However, when I turned off the cruise control and the car slowed down, the...

    Cruise Control

    When I activate cruise control the car takes control of the steering some times. Is there a solution for the problem? I have an MG4 trophy long range model. Just completed my first public charging at Bury St Edmunds at Waitrose who had about 10 chargers. John

    Cruise control unable to maintain speed

    Majority of our motorways are not flat, having slight bumps or inclines/declines. Our 2 month old ZS struggles on these, with a constant increase in power and immediately, decrease in power before repeating this process over and over. Feels your on a boat riding the waves. On the same roads, our...
