Hyundai Tucson passenger airbag on and check exhaust warning lights

I need to know if my car is safe to drive from London to the Isle of Wight tomorrow. The main concern is a Passenger Airbag On sign illuminated with, after a delay, SRS in red underneath it. Not on the dashboard. If I am able to disarm that Airbag, should I do that? A lesser concern is a Check Exhaust warning sign. We have got a local garage to do a diagnostic check on that and they can find nothing of concern. But we cannot get the car to a Hyundai garage for another 10 days. I would be most grateful for any advice on next steps.
