Operation Driving instructions Brake pad wear or a leak in the system may be the reason for low brake fluid 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 347). Observe additional messages in the multifunction display that may appear ( page 374). Have the brake system inspected immediately. Contact an authorized Mercedes-Benz Center. 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! G 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). 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. Be certain to read and observe the warning notices on brake pad replacement ( page 373). ! 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 will cool down the brakes faster. 273
