Practical hints What to do if ... Left display Right display Possible cause/ consequence There are malfunctions, but the electro-hydraulic brake system is operating normally. You are driving with the parking brake set. The brake pads have reached their wear limit. Possible solution Contact an authorized Mercedes-Benz Center immediately. Release the parking brake ( page 49). Have the brake pads replaced as soon as possible. ; 3 (USA only) Brake Service (Canada only) Required Release Parking Brake 2 Brake Wear ! Brake pad thickness must be visually checked by a qualified technician at the intervals specified in the Maintenance Booklet. Excessive load on the brake system causes increased wear of brake pads and brake disks. If the brake pads have to be replaced multiple times within one maintenance service interval, the brake disks must be checked. Observe the information given in the Maintenance Booklet and contact an authorized Mercedes-Benz Center. Warning! G Have brake pad replacement and other work on the electro-hydraulic brake system carried out by qualified technicians only. Contact your Mercedes-Benz Center for further information. The electro-hydraulic brake system must be deactivated prior to working on the system. High pressure is intermittently built up in the system as part of its automatic self-test. In addition, the system is automatically activated when the vehicle is unlocked by remote control, when the driver or passenger door is opened, when the SmartKey in the starter switch is turned to position 1, when the brake pedal is depressed or when the parking brake is released. Failure to deactivate the system prior to maintenance will cause brake pistons to extend and brake fluid to leak, which may result in injuries (contusions and acid burns), see "Electro-hydraulic brake system" ( page 87). 339
