Something misleading is something which communicates the wrong idea. The signposting at Heathrow Airport is very misleading.
Deception and deceit involve being deliberately misreading - usually for bad purposes. Strangely, though, we usually use 'deceptive' to mean 'misleading' without necessarily implying any deceitful purpose, i.e. they mean the same. When driving at speed on the motorway, the car in front is deceptively close.
