Notes: The malfunction indicator lamp for the ESP is combined with that of the BAS. The yellow BAS/ESP malfunction indicator lamp in the instrument cluster and the yellow ESP warning lamp v in the speedometer dial come on with the key in steering lock position 2. They should go out with the engine running. If the BAS/ESP malfunction indicator lamp comes on permanently with the engine running, a malfunction has been detected in either system. Only partial engine output will be available. If the BAS malfunctions, the brake system functions in the usual manner, but without BAS. If the BAS/ESP malfunction indicator lamp comes on, have the BAS or ESP checked at your authorized Mercedes-Benz Center as soon as possible. With the ABS malfunctioning, the ESP is also switched off. Driving the vehicle with varied size tires will cause the wheels to rotate at different speeds, therefore the ESP may activate (yellow ESP warning lamp in speedometer dial comes on). For this reason, all wheels, including the spare wheel, must have the same tire outside diameter. When testing the parking brake on a brake test dynamometer, the engine must be shut off. Otherwise, the ESP will immediately be engaged and will apply the rear wheel brakes. In winter operation, the maximum effectiveness of the ESP is only achieved with Mercedes-Benz recommended M+S rated radial-ply tires and/or snow chains. Synchronizing ESP If the power supply was interrupted (battery disconnected or empty), the BAS/ESP malfunction indicator lamp may be illuminated with the engine running. Turn steering wheel completely to the left and then to the right. The BAS/ESP malfunction indicator lamp should go out.
