Starting the engine
NOTICE - Accelerator pedal stroke (optional) If the vehicle is equipped with a sudden acceleration control on the accelerator pedal, it prevents unintentional driving with the throttle fully open, as it requires the driver to apply more force when pressing the accelerator pedal. However, if the pedal is pressed to about 80%, the vehicle will be driven with the throttle fully open and the accelerator pedal will be easier to press. This is not a malfunction, but a normal condition.
