Bas/slr light is on and car seems disabled won't move over 5-10 miles per hour. on 1999 Mercedes-Benz S320

Battery went dead while car was parking. When I did the jump start it ran OK but lost throttle as the bas/slr light came on. Installed new battery but still light is on and throttle is not operational.
