246 Driving instructions Only install brake pads and use brake fluid recommended by Mercedes-Benz. system which is not covered by the Mercedes-Benz Limited Warranty. If your brake system is only subjected to moderate loads, you should occasionally test the effectiveness of the brakes by applying above-normal braking pressure at higher speeds. This will also enhance the grip of the brake pads. G Warning! If other than recommended brake pads are installed, or other than recommended brake fluid is used, the braking properties of the vehicle can be degraded to an extent that safe braking is substantially impaired. This could result in an accident. G Warning! Operation ! Vehicles with 4MATIC: Only conduct operational or performance tests on a two-axle dynamometer. If such tests are necessary, contact an authorized 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. ! Vehicles without 4MATIC: 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 or the vehicle is being towed with one axle raised. Active braking action through the ESP® may otherwise seriously damage the brake system which is not covered by the Mercedes-Benz Limited Warranty. ! Vehicles with 4MATIC: 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 Make sure not to endanger any other road users when carrying out these braking maneuvers. Refer to the description of the Brake Assist System (BAS) (Y page 63). High-performance brake system The high-performance brake system is only available on ML 63 AMG. G Warning! New vehicle brake pads and disks, and replacement brake pads and disks may take several hundred miles of driving until they provide optimum braking efficiency. Until that time, you may need to use increased brake pedal pressure while braking. Please be aware of this and adjust your driving and braking accordingly during this break-in period. Excessive high-demand braking will cause correspondingly high brake wear. Please be attentive to the brake warning lamp in the instrument cluster and brake condition messages in the multifunction display. Especially for high-performance driving, it is important to maintain and have the brake system checked regularly. The high-performance brake system is designed to operate under the extremely high operating demands required to accommodate the performance capabilities of the vehicle.
