It monitors the vehicle's traction (force of adhesive friction between the tires and the road surface) and handling. The ESP® recognizes that the vehicle deviates from the direction of travel as intended by the driver. By applying brakes to individual wheels and by limiting the engine output, the ESP® works to stabilize the vehicle. The ESP® is especially useful while driving off and on wet or slippery road surfaces. The ESP® also stabilizes the vehicle during braking and steering maneuvers. The ESP® warning lamp d in the instrument cluster comes on when you switch on the ignition. It goes out when the engine is running. The ESP® warning lamp d in the instrument cluster flashes when the ESP® is engaged. Never switch off the ESP® when you see the ESP® warning lamp d flashing in the instrument cluster. In this case proceed as follows: RWhen RWhile 65 G Observe Safety notes, see page 63. Mercedes-Benz Center. You could otherwise seriously damage the brake system or the transfer case which is not covered by the Mercedes-Benz Limited Warranty. ! Because the ESP® operates automatically, the engine and ignition must be shut off (SmartKey in starter switch position 0 or 1 or KEYLESS-GO start/stop button in position 0 or 1) when the parking brake is being tested on a brake test dynamometer. Such testing should be no longer than 10 seconds. Active braking action through the ESP® may otherwise seriously damage the brake system which is not covered by the Mercedes-Benz Limited Warranty. ! The ESP® will only function properly if you use wheels of the recommended tire size as specified in the "Technical data" section of this Operator's Manual. i The Distronic system and cruise control switch off automatically when the ESP® engages. Electronic Traction System (4-ETS) G Observe Safety notes, see page 63. The 4-ETS (four-wheel Electronic Traction System) is a component of the ESP®. The 4-ETS improves the vehicle's ability to utilize available traction, especially under slippery road conditions by applying the brakes to a spinning wheel. In addition, more power is transferred to the wheel(s) with traction. When you switch off the ESP®, the 4-ETS is still enabled. Switching off the ESP® G Warning! The ESP® should not be switched off during normal driving other than in the G Warning! driving off, apply as little throttle as possible. driving, ease up on the accelerator pedal. RAdapt your speed and driving style to the prevailing road conditions. Failure to observe these guidelines could cause the vehicle to skid. The ESP® cannot prevent accidents resulting from excessive speed. ! Only conduct operational or performance tests on a two-axle dynamometer. If such tests are necessary, contact an authorized Z Safety and security
