Many Citroën vehicles are equipped with an onboard computer. This system will help you assess your capacity to save fuel.
The "current fuel consumption" function shows you the extent to which fuel consumption can vary depending on how you use the accelerator pedal. It shows you how you can reduce fuel consumption by taking your foot off the accelerator when you have reached your optimum gear for your speed.
If you often make the same journey, the "average consumption" function shows you how much fuel you save by anticipating traffic problems and driving at a steady speed.
