Re setting service ASSYST following service W168 only
See my CD Rom details for W169 reset procedure


Following each service it will be necessary to re-set the service Assyst, this should be undertaken as part of the service, by the garage or persons under taking the service.

Next service due (ASSYST) Active Service System
Service Indicator
Service type
'A' small service will be denoted by a single spanner
'B' is Service will be indicated by a double spanner and is a larger service.
Mercedes-Benz recommend that services be undertaken by their service centres at which time the Assyst will be re-set. However should you not have the service undertaken by them, the Assyst indicator can be re-set by the owner or the garage where the car is serviced.


Procedure for re-setting Assyst.(W168 only)
*Turn the ignition key to position two(2) and immediately press the select button situated to the left and behind the steering wheel. twice within the space of one(1) second.
* Turn to key to position off (0 in the ignition
* Press and hold the button Turn the ignition key to position two (2) Keep select button Pressed.
* The service indicator with the current remaining distance or remaining time appears
* After about ten seconds an acoustic signal will be heard and the service indicator with the new starting distance or time appears for about ten seconds
* Release select button.

Note If the service is not carried out within the period indicated by the ASSYST the display will flash with a minus - sign in front and a warning tone will sound when the ignition is turned on.
If the battery is disconnected the period of disconnection will not be recorded by the service indicator.
* the distance between individual services depends on the style of driving. A moderate style of driving with medium engine speeds and avoiding short journeys will allow a greater mileage between services. Mercedes-Benz handbook page 111 edition 30/04/2001


The following advise is given by Mercedes where the ASSYST service indicator cannot be re-set, don't confuse this with the fact that you are not using the correct procedure or just haven't got the knack!
*Turn the ignition key to position ) and remove
* Pull fuses 28, 30 ( be aware that you alarm may go off)
* wait for 2 seconds
*Insert Key and turn to position two
*Continue with re-set procedure as above.

Note Despite what Mercedes-Benz say in the owners manual, the car's assyst will request a service 'A' or 'B' every year almost to the day or after 10000 miles, driving style as mentioned above appears to make very little difference and changing the oil between services does not increase the period. So if you have your car serviced , garage it and go on your twelve months cruise! when you start you car the instrument cluster sign and the credible alarm will tell you the car wants servicing.

Procedure to be followed having removed Battery or where the Battery has gone flat.(fully discharged)

Where the voltage supply has been interrupted, the electric windows and ESP/ABS will need to be re-set.

Re-setting ABS/ESP
* With the ignition key in position 2 turn the steering wheel fully left then fully right.
* The ESP/ABS warning light on the dash board display should go out.

*Moving the car slowly will reduce the amount of force required to turn the steering wheel.(Two shiny covered magazines placed under the tyre of each front wheel will also reduce the amount of force placed on steering components when turning the steering wheel if stationary.

Re-Setting Windows
* Turn the ignition key to position two (2)

* Fully press on the switches, in turn, in the direction until the widow is fully closed.
* Then hold the switch in that position for approx 1 second.
* Repeat this procedure for all side windows using the appropriate switch.

Setting the Clock



















To set the clock both of the features shown are used.:-
*Press and hold Button marked A
 *When the numerals in the hour display flash, correct the hour display using buttons C or D + or -
* To set the minutes, briefly press button A *The minute display will flash, to correct use buttons C or D + or -
*When the clock is correct briefly press button A
* The time displayed should now be correct.



Activating display

*Information such as time , outside temperature, remaining distance to next service, trip meter recording or oil level can be called up even when the vehicle is stationary. The display is activated by :- * Turning the ignition key to position 1 or 2.in the ignition lock.

*Opening the drivers door.
*Briefly pressing one of the buttons 1,2,3,or 4
*Switching on the vehicle lights

(The display switches off automatically after approx.30 secs.)

*The total mileage covered is shown when the display is activated
*To dim brighten the instrument lighting:-Press adjust button 3 or 4
*To call up the the trip meter briefly press button 1
* To display outside temperature, briefly press button 2
 *When pressing button 1 the mileage along with a single or double spanner may also appear. Single spanner = 'A' Small service, double spanner = 'B' Larger service. The mileage indicating when the next service is due.
(The mileage displayed does not take into account the driving style and engine idle time which are deducted from the credited mileage as the service period nears, in the case of my car this accounted for a deduction of some 1500 miles from the credited figure.

Re-setting trip meter
Allows you to record the mileage on a given trip or record the mileage for a tank of fuel etc. * Open drivers door
* press and hold button marked 1 above.

Examples of display








A Mileage trip recorded. B Trip zeroed. C Total mileage run.








D Outside temperature display. E Next service due = 'B' Service in 7200 miles. F Checking oil from cabin.
To check the oil from the cabin. * The vehicle must be on level standing
* Check the oil about 5 minutes after stopping the engine which should have reached it's regular operating temperature.

*Turn the ignition key to position 2 in the ignition lock and wait for 10 secs until the oil can symbol appears with the dial clock
*press button one above twice (2) within one (1) second.
* symbols OK, 1.0L 1.5L or 2.0L will appear the numerals denote the amount of oil required
in the engine.


The two symbols oil can & clock show together, press button (1) = 000.0 twice within 1 second and the display will indicate the status of the oil level,












This check would normally be done before starting the engine.

However if you start and then the stop the engine any attempt to read the oil level will fail. The clock will flash indicating that you need to allow more time to elapse before checking again.

(I for my part would always check the oil on the dip stick before putting oil into the engine. If the clock flashes as in the animated photo, leave the car for a least 5 mins before attempting to read the oil level again.
DO NOT OVERFILL )
If the engine sump is overfilled and indicator will show on the dash along with and audible warning the letter HI will appear. If should occur after a service as is more likely the case you are advised to return the car to the garage and ask for the level to be corrected . BUT check the oil level using the dip stick while the car is on level standing first. IF you overfilled it, use a piece of windscreen washer hose ,insert it down the dip stick hole into the sump and siphon the overfill out the warning will then cease

Jump Starting This is what MB say in their handbook:-
*1 Never try to start the engine if the battery has frozen, thaw the battery first.
*2 Only use batteries with the same Voltage rating.
*3 Use jump leads of adequate cross-section, with insulated battery terminal clamps.
*4 Switch off all electrical consumers.
*5 Connect the positive terminals on the batteries together first.
*6 Run the donor vehicles engine at idling speed.
*7 Connect the negative terminals of the two batteries together with the jump lead.



Charging the Battery
Disconnecting the Battery * Before attempting to remove the battery pull the breather tube from the battery, remember to refit after refitting the battery.

* DO NOT disconnect the battery connections from the battery while the engine is running. This could damage the electronic components (e.g. the alternator ) beyond repair
* Switch off all electrical consumers
* Loosen and remove the negative terminal first followed by the positive terminal.

NOTE when the battery is removed the ignition lock Cannot be turned

Reconnecting the Battery * All electrical consumers must be switched OFF

* Connect the positive terminal first followed by the negative,

*MAKE SURE THE BATTERY TERMINALS ARE NOT ACCIDENTLY INTERCHANGED

After reconnecting the battery the following operations will be required.
*Re-set the clock.

*Where appropriate enter the radio code.
* Reset the side windows
*Reset the ESP system
Editorial status;-30.04.2001 page 301.>
Please note. Following a number of instances where the ECU management light lit when the battery was reconnected, with the result that a visit has to be made to a garage with start diagnostics equipment to delete the light, It was suggested to one owner who suffered the problem, by the MB Service centre that in future the owner would be well advised to turn his side lights ON prior to reconnecting the battery, he was told that this action would reduce the surge of power going to the ECU when the negative terminal is connected. IT certainly sounds logical to me, I leave it up to owners whether they follow this advise, but unless you have a very helpful garage owner it could cost 2/3 the cost of a new battery just to get the ECU lamp fault deleted.
