ABS warning light -K47- t  If the ABS warning light -K47--1- does not go out after the ignition is switched on and after completion of the test sequence, the causes of the fault may be: a -  the supply voltage is less than 10 volts b -  an ABS fault is present   WARNING If an ABS fault -b- is present, the anti-lock brake system remains switched off while the conventional brake system remains fully operational. c -  a sporadic fault existed on a wheel speed sensor after the last vehicle start In this case the ABS warning light -K47- goes out automatically after restarting the vehicle and after a speed above 20 km/h is reached. d -  the connection from the dash panel insert to the ABS control unit -J104- is interrupted → Current flow diagrams, Electrical fault finding and Fitting locations. e -  the dash panel insert is defective

Warning light for traction control system -K86- t  If the warning light for traction control system -K86--2- does not goes out after the ignition is switched on and after completion of the test sequence, the causes of the fault may be: There is a fault which exclusively effects the TCS. The ABS and EBD safety systems on the vehicle remain fully functional ⇒ Interrogate the fault memory. a -  Short circuit to positive in traction control system switch -E132- b -  a fault in the actuation of the warning light for traction control system -K86- → Current flow diagrams, Electrical fault finding and Fitting locations. c -  the TCS system was switched off using the traction control system switch -E132-:    - on vehicles up to CW 44/09, the warning light remains lit    - on vehicles as of CW 45/09, the warning light flashes slowly If the warning light for traction control system -K86- flashes quickly while driving, the TCS system is operating in regulating mode. t  If the warning light for traction control system -K86--2- does not light up during the automatic test sequence then the following error is present: a -  the warning light for traction control system -K86- is defective, carry out electrical test.

ESP and TCS warning light -K155- t  If the warning light for ESP and TCS -K155--2- does not go out after the ignition is switched on and after completion of the test sequence, the causes of the fault may be: There is a fault which exclusively effects the TCS/ESP. The ABS/EDL and EBD safety systems on the vehicle remain fully functional. In this case undertake „Interrogate the fault memory“ → Vehicle diagnostic tester. a -  Short circuit to positive in TCS and ESP button -E256- b -  a fault in the actuation of the ESP and TCS warning light -K155- → Current flow diagrams, Electrical fault finding and Fitting locations. c -  the ESP system was switched off using the TCS and ESP button -E256- - the warning light flashes slowly.   Note If the ESP system is switched off (only the TCS system is switched off), the warning light flashes slowly.   Note If the battery was disconnected and reconnected, the ESP and TCS warning light -K155- lights up after switching on the ignition. It must go out after driving a short distance. If the warning light for ESP and TCS -K155- flashes while driving, the TCS or the ESP system is operating in regulating mode.   Note t  If the ESP system is operating in regulating mode, the warning light flashes rapidly. t  If the ESP system is switched off (only the TCS system is switched off), the warning light flashes slowly. t  If the warning light for the ESP and TCS -K155--2- does not light up during the automatic test sequence then the following error is present: a -  the warning light for the ESP and TCS -K155- is defective, carry out electrical test.

ABS warning light -K47- and dual circuit and hand brake system warning light -K7- t  If the ABS warning light -K47--1- goes out or the dual circuit and hand brake system warning light -K7--3- lights up, the causes of the fault may be: a -  the hand-brake is still applied b -  the brake fluid level is too low (warning light flashes) On switching on the ignition three warning tones are audible. c -  There is a fault on the lines to the dual circuit and hand brake system warning light -K7- → Current flow diagrams, Electrical fault finding and Fitting locations t  If the ABS warning light -K47- (-1-) and the dual circuit and hand brake system warning light -K7- (-3-) light up, the ABS system is defective. One must reckon with a somewhat changed braking characteristic.   WARNING Once the ABS warning light -K47- and the dual circuit and hand brake system warning light -K7- have lit up then the rear wheels lock quite early on when braking. t  If the dual circuit and hand brake system warning light -K7--4- does not light up during the automatic test sequence, then the following fault is present: a -  the dual circuit and hand brake system warning light -K7- is defective, carry out electrical test

Brake pad warning light -K32- t  If the warning light for the brake pad -K32--4- does not go out 3 seconds after switching the ignition on or glows during the driving operation, the following can be the causes of the fault: a -  the brake pads could be worn down –  Check the brake pads on the front and rear axles. Replace the brake pads if they are worn down. b -  there is a fault in the wiring → Current flow diagrams, Electrical fault finding and Fitting locations. t  If the brake pad warning light -K32--4- does not light up during the automatic test sequence then the following error is present: a -  the brake pad warning light -K32- is defective, carry out electrical test.   Note On vehicles with information display, the brake pad warning light -K32- does not light up after switching on the ignition, only in the event of a fault.

Warning light for tyre pressure display -K220- t  Warning light for tyre pressure inspection display -K220--5- comes on: –  Carry out tyre pressure inspection. –  Correct the tyre inflation pressure. –  Perform basic setting. Basic setting: l  Ignition on

–  Press the button for tyre pressure inspection -E226--arrow B- for more than 2 seconds. When the button for tyre pressure inspection -E226- is pressed the warning light for tyre pressure inspection display -K220- lights up in the dash panel insert. The basic setting is confirmed with an acoustic signal and when the warning light goes out. –  Switch off ignition. –  After the ignition is switched on again, the warning light for tyre pressure inspection display -K220- does no longer light up. t  Warning light for tyre pressure inspection display -K220- flashes: –  Carry out tyre pressure inspection. –  Correct the tyre inflation pressure. l  Ignition on

–  Press simultaneously the button for tyre pressure inspection -E226--arrow B- and the traction control system switch -E132- or the TCS and ESP button -E256--arrow A- for more than 2 seconds.   Note Depending on the equipment, the traction control system switch -E132- can be mounted instead of the TCS and ESP button -E256-. If the warning light for tyre pressure inspection display -K220- continues to flash: –  Undertake „Targeted fault finding“ → Vehicle diagnostic tester.

Warning light for Downhill Drive Support -K250- t  If the warning light for Downhill Drive Support -K250--6- does not go out after the ignition is switched on and after completion of the test sequence, the causes of the fault may be: a -  Short circuit to positive in button for Downhill Drive Support -E618- b -  a fault in the actuation of the warning light for Downhill Drive Support -K250- → Current flow diagrams, Electrical fault finding and Fitting locations.   Note The warning light for Downhill Drive Support -K250- lights up if the driving speed drops below 30 km/h, after the button for Downhill Drive Support was pressed. Further information can be found in the instructions for use. If the warning light for Downhill Drive Support -K250- flashes while driving, the Downhill Drive Support system is operating in regulating mode. t  If the warning light for Downhill Drive Support -K250--6- does not light up during the automatic test sequence then the following error is present: a -  the warning light for Downhill Drive Support -K250- is defective, carry out electrical test.
