Operation Driving instructions All checks and service work on the brake system should be carried out by qualified technicians only. Contact an authorized Mercedes-Benz Center. Only install brake pads and brake fluid recommended by Mercedes-Benz. Warning! High-performance brake system (CLK 63 AMG only) The high-performance brake system is designed to operate under the extremely high operating demands required to accommodate the performance capabilities of the vehicle. The brakes may produce a squeaking-type noise depending on the vehicle speed brake force applied ambient conditions, e.g. temperature and humidity As with any brake system, the wear of individual brake system components such as brake pads or discs strongly depends on your driving style and the conditions under which you operate the vehicle. Thus, a driving style calling for high demand braking will cause your vehicle's brakes to wear more quickly. Warning! G 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) ( page 90). Brake pad wear or a leak in the system may be the reason for low brake fluid level in the reservoir. The brake fluid level in the reservoir may be too low if the brake warning lamp in the instrument cluster comes on and an acoustic warning sounds although the parking brake is released ( page 368). Observe additional messages in the multifunction display that may appear ( page 389). Have the brake system inspected immediately. Contact an authorized Mercedes-Benz Center. G 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. ! When driving down long and steep grades, relieve the load on the brakes by shifting into a lower gear to use the engine's braking power. This helps prevent overheating of the brakes and reduces brake pad wear. After hard braking, it is advisable to drive on for some time, rather than immediately park, so that the air stream can cool down the brakes faster. 303
