First drive cycle

The first time a leak is detected a "TIGHTEN FUEL CAP" message appears in the multi-information display (A). To scroll to another message, press the select/reset button. The "TIGHTEN FUEL CAP" message will appear each time you restart the engine until the system turns the message off. Turn the engine off then replace or tighten the fuel fill cap until it clicks at least once.
