Notes: The yellow ESP warning lamp v in the speedometer dial comes on with the electronic key in starter switch position 2. It should go out with the engine running. If the ESP warning message is displayed, a malfunction has been detected in the system. Pressing the accelerator pedal will require greater effort. Only partial engine output will be available. Have the ESP checked at your authorized Mercedes-Benz Center as soon as possible. For ESP warning message, see page 273. 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 size. 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 ESP warning message may be displayed with the engine running. Turn steering wheel completely to the left and then to the right. The ESP warning message should go out.
