Service intervals are indicated on a digital display located on the dashboard. The first indication of the need for maintenance appears approximately one month or 3,000 km before the current maintenance date.
Service indication on the universal display appears automatically after switching on the ignition or while driving.
The following messages may appear:
- «SERVICE A» «IN xx DAYS» (LIST A... IN xx DAYS)
- «SERVICE A» «IN xx KM» (LIST A... AFTER mileage xx km)
- «SERVICE A» «EXCEEDED BY xx DAYS!» (LIST A SERVICE... OVERDUE BY xx DAYS!)
- «SERVICE A» «EXCEEDED BY xx KM!» (LIST A SERVICE... OVERDUE BY xx KM!)
- «SERVICE A» «CARRY OUT!» (LIST A SERVICE... DO IT!)
Indication «SERVICE A» (LIST A SERVICE) or «SERVICE B» (LIST B SERVICE) provide information on what maintenance needs to be done.
Depending on the driving style, the maintenance period is displayed in days or in kilometers (km).
If the maintenance period is overdue, an additional sound signal is activated.
Service indication automatically turns off after 30 seconds or by pressing the reset button on the dashboard (Section 9 Chapters «Controls and techniques for safe operation»).
Service display call
Turn the key in the ignition switch to position 1 or 2.
Using the or button on the multifunction steering wheel, call up the indication of the mileage meter since the reset and the total mileage counter (Chapter Multifunction steering wheel, universal display).
Press the or button until the TO indication appears.
By pressing the or button, the next or previous system is displayed.
Important! The service indicator does not display the engine oil level. The call for indicating the level of impellent oil is discussed below.
The mileage between two service intervals depends on the driving style.
A relaxed driving style at medium engine speeds and a reduction in the number of trips for short distances increase the vehicle's life (more information in «service book»).
Note. If the battery is disconnected, the service indicator does not take into account idle time.
To comply with the terms of maintenance, it is necessary to take into account this period of time.
Resetting the maintenance indicator after maintenance
Turn the key in the ignition switch to position 1.
Use the or button on the multifunction steering wheel to display the mileage meter since reset and the total mileage counter.
Press the or button until the TO indication appears.
Reset button on dashboard (Chapter Dashboard) press and hold for approximately 2 seconds.
The universal display prompts: «DO YOU WANT TO RESET SERVICE INTERVAL?» «CONFIRM BY PRESSING R» (DO YOU WANT TO START A NEW COUNTDOWN THAT? - CONFIRM BY PRESSING THE RESET BUTTON).
Press the reset button on the dashboard again, the indication of the maintenance period is reset.
The TO indication appears with a new countdown of the mileage since the start.
If the TO indicator was reset by mistake, the indicator readings can be updated at the service station «Mercedes-Benz».
Engine oil level indicator
When checking the oil level, the vehicle must be in a horizontal position.
Check the oil level approximately 5 minutes after stopping warmed up to operating temperature.
Turn the key in the ignition switch to position 2.
Use the or button on the multifunction steering wheel to display the mileage meter since reset and the total mileage counter (Chapter Multifunction steering wheel, universal display).
Press the or button on the multifunction steering wheel until the engine oil level indicator appears «MEASUREMENT CORRECT ONLY IF VEH. LEVEL!» (ACCURATE MEASUREMENT IS POSSIBLE ONLY IN THE HORIZONTAL POSITION OF THE VEHICLE!) This indication appears only as a reminder; if the car is not in a horizontal position, the measurement can be interrupted by pressing the or buttons. If the measurement is not interrupted, this will lead to an erroneous measurement - bring the car to a horizontal position and repeat the measurement.
If a message appears «ENGINE OIL LEVEL» «SWITCH ON IGNITION!" (ENGINE OIL LEVEL - SWITCH OFF THE IGNITION!), then the key in the ignition switch is not in position 2.
Approximately 3 seconds later, the display appears «ENGINE OIL LEVEL» «MEASURING NOW!» (ENGINE OIL LEVEL - MEASURING IN PROGRESS!)
The following indications may appear on the display:
- «ENGINE OIL LEVEL» «OK» (ENGINE OIL LEVEL OK). Topping up oil is not required.
- «ENGINE OIL LEVEL» «ADD 1,0 LITER!» (ENGINE OIL LEVEL - ADD 1.0 LITERS OF OIL!)
- «ENGINE OIL LEVEL» «ADD 1,5 LITER!» (ENGINE OIL LEVEL - ADD 1.5 LITERS OF OIL!)
- «ENGINE OIL LEVEL» «ADD 2,0 LITER!» (ENGINE OIL LEVEL - ADD 2.0 LITERS OF OIL!)
- «ENGINE OIL LEVEL» «REDUCE OIL LEVEL!» (ENGINE OIL LEVEL - LOWER OIL LEVEL!) appears only when the engine is warmed up to operating temperature.
Excess oil must be drained or pumped out. There is a risk of engine or catalytic converter damage.
«WAITING TIME» «OBSERVE!» (KEEP THE WAIT TIME!)
This display appears if the required waiting time after switching off the engine has not been taken into account.
After turning off the engine, wait the following time:
- When the engine is warmed up to operating temperature - about 5 minutes;
- When the engine is not warmed up to operating temperature - up to 30 minutes.
Repeat the oil level measurement after the appropriate waiting time has elapsed.
Note. If the oil level indication appears on the universal display while the engine is running, see «Warning system and fault signaling» (Chapter Warning and warning lamps, as well as information display messages about registered faults).
The oil level cannot be monitored while the engine is running, the indication appears «ENGINE OIL LEVEL» «NOT WHEN ENGINE ON» (DO NOT CHECK THE ENGINE OIL LEVEL WHILE THE ENGINE IS RUNNING).
On models with a four-cylinder petrol engine, the oil level can also be measured with an oil dipstick (refer to section Checking fluid levels, leak control).
