|
|
|
| Item | Designation |
| 1 | ABS warning lamp -K47- |
| 2 | ESP warning lamp -K155- |
| 3 | Brake system warning lamp -K118- |
| 1 - | ABS warning lamp -K47- |
|
q
| Lights up for a few seconds when the ignition is switched on and goes out after the automatic ABS self-test has been completed, providing no faults have been detected in the ABS. |
|
q
| There is a malfunction of the ABS if the warning lamp: |
| t
| does not light up when the ignition is switched on, |
| t
| does not go out again after a few seconds, |
| t
| lights up while the vehicle is in motion. |
|
q
| Malfunctions in the ABS system do not influence the brake system itself. However, a change in braking behaviour must be reckoned with. |
| If the ABS warning lamp -K47- does not go out after the ignition has been switched on and test sequence has been completed, the cause of the fault may be: |
| t
| Voltage supply is below 10 Volt. |
| t
| There is a fault in the ABS. |
| t
| In the event of an ABS fault, the anti-lock brake system remains switched off, but the brake system remains fully operational. |
| t
| A speed sensor fault has occurred since the last time the vehicle was started. |
| t
| In the event of a speed sensor fault, the ABS warning lamp -K47- will go out after the engine is restarted when road speed exceeds 2.75 km/h. |
| ABS warning lamp -K47- and brake system warning lamp -K118- |
| If the ABS warning lamp -K47--1- goes out but the brake system warning lamp -K118--3- remains on, the causes of the fault may be: |
| t
| The handbrake is applied. |
| t
| The brake fluid level is too low. |
WARNING | If the ABS warning lamp -K47- and the brake system warning lamp -K118- have lit up, it is possible that the rear wheels will lock up earlier. |
|
| 2 - | ESP warning lamp -K155- |
|
q
| Flashes while driving when the ESP or traction control system is taking control action |
|
q
| Lights up when the ignition is switched on and goes out after a short self-test has been completed |
|
q
| Lights up if there is a malfunction in the ESP |
|
q
| Lights up if there is a malfunction in the ABS (the ESP and ABS systems work together) |
|
q
| Lights up during automatic self-adaption of the sensor systems when: |
| t
| the battery has been disconnected and then re-connected |
| t
| the vehicle has been jump-started |
| t
| the battery charge level is very low |
|
q
| The ESP warning lamp goes out after the vehicle has been driven a short distance as soon as the automatic self-adaption of the sensor system is completed |
Note
| t
| If the ABS warning lamp lights up together with the warning lamp for ESP/ASR (electronic stabilisation program and traction control system), this indicates a fault in the ABS and electronic differential lock. |
| t
| The vehicle can still be braked with normal braking power, but the ABS function is not available. |
| 3 - | Brake system warning lamp -K118- |
|
q
| Lights up if the brake fluid level is too low |
|
q
| Lights up if there is a fault in the ABS system |
|
q
| Lights up if there is a fault in the electromechanical parking brake |
|
q
| Lights up if a brake pad has reached its wear limit |
|
q
| Lights up together with ABS warning lamp if ABS should fail |
|
q
| Flashes if there is a fault in the brake system |
