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.
ESP control switch
ESP control switch located on center console.
To improve the vehicle’s traction when driving with
snow chains, or starting off in deep snow, sand or gravel,
switch off ESP by pressing the upper half of the ESP
switch. The ESP warning lamp , located in the
speedometer dial, is continuously illuminated.
