What it means
The vehicle has limited engine output, often to protect the engine or drivetrain or to allow limited operation after a fault. Amber commonly means check the vehicle soon, but the colour and exact behaviour vary by manufacturer.
What the symbol looks like: A warning message such as “Reduced engine power” or “Engine power limited”; wording and graphics vary by manufacturer.
Why it comes on
- Throttle or accelerator-pedal control fault
- Engine sensor fault
- Turbocharger or boost-control problem
- Overheating or another condition that triggers protection
- Transmission or emissions-system fault
What to do
- Ease off the accelerator and avoid demanding rapid acceleration.
- Check the owner's manual and any accompanying warning messages.
- If temperature or oil-pressure warnings appear, stop safely and follow the manual's instructions.
- Arrange diagnosis promptly; seek roadside assistance if the vehicle cannot maintain a safe speed.
Can I keep driving?
Continue only as far as needed to reach a safe place if the vehicle remains controllable and no serious warning is present. Avoid high speeds, overtaking, steep climbs, and heavy loads.
Symbols and colours differ between makes and models. Your owner’s manual shows the exact lights of your car.
