From warning lights to shuddering, our Car Doctor can help.
To reset the oil change warning light please follow these steps. Turn the key ignition on (not the engine) then hold down the brake and accelerator for 20 seconds. The warning light should then turn off. If this doesn’t work, it would be best to visit a dealership.
This may be due to the rechargeable nickel-metal-hydride (Ni-MH) battery in the car’s hybrid system gradually decreasing in its ability to retain charge. If the battery is holding less charge, the hybrid system is less able to use its electric drive capability and so must use the petrol engine more regularly, which would decrease the vehicle’s range. Alternatively, it could be an issue with the calibration of the car’s electronics. An automotive workshop will be able to confirm either scenario.
