Frequently Asked Questions
Why is the Service Vehicle Soon Light on in my Porsche 718 Boxster?
On a Porsche 718 Boxster, the Service Vehicle Soon Light comes on because a monitored value crossed a threshold the car considers abnormal.

Can I keep driving with the Service Vehicle Soon Light on?
It depends on the urgency (moderate) and how your Porsche 718 Boxster is behaving. If the light is red or flashing, or the car drives differently, stop safely and get help. If it is amber and everything feels normal, you can usually drive to a workshop soon — just do not put off the diagnosis.
