BMW Service Symbols

What are the Service Icons on my Dashboard?

You may be new to owning a BMW, you may have had one for years and you still don’t know. Please see below information on what the icons mean and what action you need to take to remedy them. Depending on the age of your BMW, your vehicle will be fitted with either the Condition Based Servicing (CBS) or Service Interval Indicator (SII) system; both of which will alert you through dashboard symbols, when your BMW needs attention.
