The yellow ESP warning lampv 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. 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 292.
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 
d ial com es on ). For  t his reas on,  all wheels,  in cludin g t he 
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.
