Safety and Security Driving safety systems SBC brake system Warning! The SBC brake system combines a hydraulic brake circuit with electronically controlled brake servo assistance. You have increased braking safety and improved braking comfort. Warning! G The SBC brake system requires electrical power to operate. A malfunction in the vehicle's power supply or electrical system may impair brake system operation and switch it into its emergency operation mode. In such a case, the red brake warning lamp ( page 326) comes on and warning messages ( page 347) appear in the multifunction display while driving. To brake, the driver must then apply significantly greater brake pedal pressure and depress the pedal much further to obtain the expected braking effect. If necessary, apply full pressure to the brake pedal. Brakes are only applied to the front wheels. Stopping distance is increased! If there is a malfunction in the SBC brake system, we recommend that the vehicle be transported with all wheels off the ground using flatbed or appropriate wheel lift/dolly equipment. A tow bar must be used if circumstances do not permit the use of the recommended towing methods and the vehicle requires towing with all four wheels on the ground. Towing the vehicle with all four wheels on the ground is only permissible for distances up to 30 miles (50 km) and at a speed not to exceed 30 mph (50 km/h). For more information, see "Towing the vehicle" ( page 408). G Never ignore a brake malfunction indicated in the speedometer display, for example by the ; (USA only) or 3 (Canada only) indicator lamp. Refer to the "Practical hints" section ( page 326). Also read and observe the messages in the instrument cluster multifunction display ( page 347). 85
