BMW 5 series E39

1. Before the beginning of procedure of service always at first switch off the engine and disconnect all electrodevices, then disconnect a negative wire from the battery.

If the radio receiver of your car is equipped by system of protection against larceny, make sure that you have typed a correct code before a battery detachment.

2. Usually cars BMW are equipped by the batteries which are not demanding special leaving. It is possible to remove covers банок and to add the distilled water. Latest models can be equipped by the batteries which absolutely not are not demanding leaving which are completely sealed.

3. The storage battery is in a luggage carrier under the right lateral facing. Cast away for the handle facing back.

4. Uncover over the battery. For this purpose disconnect a collar.

5. Remove covers and check up electrolit level in each of банок batteries. It should be above plates approximately on 5 mm, i.e. To reach approximately the bottom edge If level more low, it is necessary to add the distilled water. For this purpose turn out stoppers (arrows on an accompanying illustration) and fill in a liquid in everyone to bank to labels, visible in apertures.
Then close covers банок.

Overflow банок can lead to transfusion of electrolit during the accelerated gymnastics that will cause corrosion and damage of the components nearest to the battery.

4. If the positive plug and a collar of a wire of the battery of your car are equipped by a rubber protector, make sure that it is not torn and not damaged. It should close the plug completely.
8 It is necessary to examine periodically an external condition of the battery on presence of such damages, as cracks in the case.
9 Check up reliability of a tightening of collars of wires of the battery, providing good electric connection. Check up each of wires on all length on presence of cracks and attritions of isolation and wires.

5. At detection of traces of corrosion (usually representing a friable touch of white colour) disconnect wires from plugs, smooth out their special brush and again connect. Corrosion occurrence can be reduced to a minimum by installation of specially processed washers which are available on sale in shops of autospare parts, or by drawing on plugs and collars of wires of a layer бескислотного vaseline or suitable greasing after their connection.
   -   Corrosion of plugs of the battery is usually shown in the form of an easy, friable powder

   -   The detachment of a wire from the plug of the battery by means of a key - sometimes when corrosion has destroyed a nut, for this procedure is required special flat-nose pliers (always the first disconnect also the last connect a grounding wire!)

   -   Irrespective of type of the adaptation for зачистки result always there should be a pure, brilliant surface of the plug

   -   At зачистке tips of wires it is necessary to remove all traces of corrosion (the internal part of a tip has конусность, repeating form of the plug of the battery, therefore do not remove too much material)

4. Make sure that the battery pallet is in a satisfactory condition, and the bolt of a fixing collar is reliably tightened. If the battery acted in film from the pallet (address to materials Has undressed Removal and installation of the storage battery, describing removal and installation procedure), track, that in an installation time on it details or other extraneous subjects did not lie. At зажимании a fixing collar do not tighten its bolt too hardly.
5. Traces of corrosion from the pallet, cases of the battery and surrounding surfaces can be removed by means of a water solution of baking soda. Put a mix a small brush, allow to it to stand and then смойте plentiful quantity at its finest.
6. Metal surfaces of the car, подвергшиеся corrosion, it is necessary to cover with a first coat on a zinc basis and then to paint.

1. Remove all covers with банок batteries (if they are available) and close apertures pure rags to prevent an electrolit spillage. Disconnect a negative wire of the battery and connect wires зарядного devices to its plugs (positive to positive, negative to negative), then include зарядное the device in a network. If it has the switch, make sure that it is established in position “12 volt”.

If the radio receiver of your car is equipped by system of protection against larceny, make sure that you have typed a correct code before a battery detachment.

2. If you use зарядным the device with a current more than two amperes, regularly check the battery during gymnastics to make sure that it has not overheated. Using slow зарядное the device, you can easy leave the battery to be charged on all night long after regular check within first two hours. At gymnastics of the batteries which are not demanding leaving, certain safety measures (for example, application very much низкоамперного зарядного devices) can be demanded. On such battery can be precautionary шильдик but if it is not present, address for consultation in dealer branch BMW or to the electrician from a repair truck.
3. If battery banks have the demountable covers, each hour within last several hours зарядного a cycle check density of electrolit with the help ареометра. Inexpensive ареометры are available on sale in shops of autospare parts - at their application follow applied instructions. It is possible to consider the battery charged if within two hours indicators of density of its electrolit do not change, and the electrolit in banks freely bubbles. The electrolit density in separate banks should be almost identical. If this not so, means, one or the several банок batteries have failed also them it is necessary to replace.
4. Some batteries not demanding leaving have above built in ареометр, having a window - the colour indicator of degree of gymnastics of the battery. The usually brightly painted window means that the battery is completely charged, and dark colour testifies to necessity of additional gymnastics. More exact instructions are resulted in the instruction of the manufacturer of the battery.
5. If the battery is sealed and has no built in ареометра, you can check up degree of gymnastics by means of connected to plugs of the battery of the digital voltmeter. Completely charged battery will show 12.6 and more volt.

1. Replace the battery if on the self-diagnostics indicator there is a message “Funkschluessel-Batt.” (A radio key Battery)

Remote control should be initialized, if battery replacement lasted more than one minute, address to materials more low.

2. Remove a casing a small screw-driver. Address to an accompanying illustration
3. Turn out two screws and uncover.

4. Replace the battery with the battery of the same type (type CR1220). Thus observe polarity. Establish the battery in too position, as old.
5. Fix a cover screws, fix a casing.
6. If necessary initialize remote control

1. Sit down for a wheel and close behind itself a door
2. Having inserted a key into the ignition lock, for a short while (a maximum for 5 seconds) turn it in position 1, and then turn in position 0
3. Take a key from the lock, press and keep the button 1 on the transmitter. Within 10 seconds execute three consecutive short-term pressing the button 2, without releasing, however, thus the button 1
4. Release the button 1
5. Operation of the uniform lock on lock-out with the subsequent immediate unlocking will be a signal of successful initialization of the transmitter
