Safety and Security Driving safety systems The electro-hydraulic brake system is automatically activated when you unlock the vehicle with the SmartKey or the SmartKey with KEYLESS-GO* open the driver's or passenger door turn the SmartKey in the starter switch to position 1 in vehicles with KEYLESS-GO*, press the start/stop button on the gear selector lever once depress the brake pedal release the parking brake Warning! G The electro-hydraulic 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 335) comes on and warning messages ( page 366) 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 electro-hydraulic 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 421). 93
