If your MG4 has one-pedal driving, it's easy to miss — the toggle lives inside the infotainment menus. One reviewer of the 2026 MG4 Urban (a related but distinct model) wrote that it took him a good ten minutes to find it (source). And even once you find it, the car won't always let you switch it on. Here's what you need to know.
Note up front: this guide applies to MG4s that actually ship with the One-Pedal function. Some early production cars (often called Phase 1 / MY22) don't have the option at all — more on that below.
How to turn it on
Per the MG4 owner's handbook, the One-Pedal function is switched ON or OFF through the entertainment (infotainment) display: find the One-Pedal toggle in the driving/vehicle settings and enable it. (Menu layout varies with software version, so if the path looks different on your car, that's expected.)
With it enabled, you control speed with the accelerator alone: press to accelerate, ease off to slow down, and the car decelerates to a complete stop.
Keep your foot hovering near the brake pedal regardless. One-pedal driving is a convenience feature — in an emergency you still brake the old-fashioned way.
Now the four catches
1. Many owners have to re-enable it every drive
This is a recurring complaint on owner forums: switch the car off and back on, and the setting is gone — you have to turn it on again. Some owners say their car remembers it, which suggests behaviour varies with software version. Treat it as a start-up step, not a set-and-forget.
It annoys people enough that a community developer published a small Android app (mg4customauto) that auto-enables OPD on boot — an unofficial workaround, not an MG product.
2. It may refuse to engage when the battery can't take more charge
Tap the toggle with a high state of charge and you may see a message like "Unavailable, low charge power". The reason: one-pedal driving slows the car by feeding energy back into the battery, and when the battery's charge acceptance is limited — high SOC, or cold conditions — the function can be unavailable.
Owner reports put the cutoff roughly between 85% and 92% (SOC discussion, temperature discussion), moving with temperature and conditions rather than sitting at one fixed number. That's forum experience, not an official threshold. So if the button says no right after a full charge, that's the car behaving as designed; try again once you've driven the charge down a bit.
3. Early cars may not have the option at all
Some early cars were built without the One-Pedal function. Availability varies by production batch and market — MG has at times added the function to existing cars via dealer software updates (reported in Australia), so it's genuinely worth asking rather than assuming. If your menu has no One-Pedal entry, ask your dealer to check against your VIN.
4. Know when it backs off on its own
The handbook lists conditions where the function is limited or exits: seat belt unfastened, a door ajar, a brake-system or power-system fault, Snow mode ON, or while an intelligent-driving function is active. The European MY23 handbook additionally lists low charge power as a limiting condition, with high charge level and low ambient temperature given as examples — so the "Unavailable, low charge power" message is handbook-backed behaviour, at least on EU-spec cars. Worth remembering in winter: switching drive modes into Snow will disable it.
And the safety fine print, straight from the manual: even though OPD can bring the car to a stop, there is still a risk of sliding on steep slopes. On a steep hill, use the brake pedal and proper parking measures — don't rely on OPD to hold the car.
Three habits owners find useful
Use the brake pedal in reverse. Owners report that OPD doesn't give the same one-pedal control when reversing — the car may creep on its own. When backing up, just drive it with the brake pedal like a conventional car.
Expect the power meter to read something at a standstill. Some owners have noticed the power meter showing a draw while the car sits "stopped" on OPD, which drops after a firm brake press engages AutoHold. That's an observation from forum posts, not a measured efficiency finding — don't read it as a general energy-saving tip.
Keep your friction brakes in use. Because regenerative braking can reduce how much the friction brakes are used, owners discuss surface corrosion as a possible side effect. The sensible version: use the brake pedal normally and regularly when conditions allow; if you notice rust, noise, or odd braking behaviour, have the brakes inspected.
The bottom line
MG4 one-pedal driving works well once it's on — the friction is all around getting it on. It hides in the infotainment menus, many cars forget the setting between drives, high charge levels can block it, and some early cars simply don't have it. Know those four, and it's a routine, not a mystery.
