My 2013 Citigo last night made the beep the 4 degree warning light came on , then next to that it started counting up to 5 with an arrow or dot at the side , it’s not gone today and it’s carried on counting up and down as I’m driving , hand book has no idea , main dealer neither , anyone on here know what it is ?

Gear indicator, up telling you to go up a gear dot saying ya in right gear and down for down a gear. All about the economy

The little number that counts up and down is the gear indicator. It shows what gear you are in, the dot shows the car 'recommends' staying in that gear, an up arrow means change up and down arrow means change down. 

Ive had the car a year first time I’ve seen it !! Thankyou so much .
