..even if battery goes dead. I would hesitate to suggest a jump start though with all the sensitive and expensive-to-repair electronics in the SL500. I have disconnected battery and used a charger to bring it back to life. In a pinch or on the road, do consult manual if jumpstarting is the only option. However in the confines of your garage/driveway, err on the side of caution and use a trickle charger.
