Check and leaving

During the work with the battery it is necessary to undertake certain security measures. At banks of the battery there is always extremely a flammable hydrogen therefore do not allow approach to the battery with the lit cigarette or other types of naked flame at all. Electrolyte of the battery represents solution of sulfuric acid which at hit in eyes or on open parts of the body causes serious injuries. Besides, acid corrodes clothes and paints. At shutdown of the battery always the first disconnect a negative wire, and connect it in the last turn!

Care of the battery is very important procedure allowing to avoid stops in way because of its discharge. Implementation of the procedure of service requires several tools.

Tools and materials necessary for care of the battery

1 — a front guard / goggles
   - during removal by a brush of traces of corrosion of a particle of the crystallized acid easily can get into eyes
2 — baking soda
   - water solution of baking soda can be used for corrosion neutralization
3 — acid-free vaseline
   - the layer of vaseline applied on battery plugs will help to avoid their corrosion
4 — the device for cleaning of plugs / tips of wires
   - such adaptation with a wire brush will remove all traces of corrosion from plugs of the battery and tips of wires

5 — the impregnated felt washers
   - installation of such washers on each plug of the battery directly under tips of wires will help to avoid corrosion
6 — a stripper
   - sometimes tips of wires appear to be removed very difficult from battery plugs, even after full weakening of nuts / bolts. This tool will help to remove tips vertically up without damages
7 — the device for cleaning of plugs / tips of wires
   - one more type of the smoothing-out tool, slightly changed version of point 4 performing the same functions
8 — rubber gloves
   - one more security measure during the work with the battery; remember that in the battery there is acid!


 PERFORMANCE ORDER

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

If the radio receiver of your car is equipped with system of protection against theft, make sure that you gathered the correct code before a battery detachment.

2. Usually the BMW cars are equipped with the batteries which are not demanding special leaving. It is possible to uncover cans and to add the distilled water. Latest models can be equipped with the batteries which are not demanding leaving at all which are completely sealed.

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

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

5. Uncover and check electrolyte level in each of battery cans. It has to be above plates approximately on 5 mm, i.e. reach approximately the lower edge If level is lower, it is necessary to add the distilled water. For this purpose turn out traffic jams (arrows on an accompanying illustration) and fill in liquid in each can the tags seen in openings.
Then close covers of cans.

Overflow of cans can lead to transfusion of electrolyte during the accelerated charging that will cause corrosion and damage of the components, next to the battery.

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

5. At detection of traces of the corrosion (which is usually representing a friable raid of white color) disconnect wires from plugs, smooth out them a special brush and again connect. Emergence of corrosion can be minimized by installation of specially processed washers which are available on sale in shops of auto parts, or by drawing on plugs and collars of wires of a layer of acid-free vaseline or suitable lubricant after their connection.
   -  Corrosion of plugs of the battery is usually shown in the form of light, friable powder

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

   -  Irrespective of type of device for cleaning the pure, brilliant surface of the plug has to be result always

   -  When cleaning tips of wires it is necessary to remove all traces of corrosion (an internal part of a tip has the conicity repeating the battery plug form therefore do not remove too much material)

4. Make sure that the pallet of the battery is in satisfactory condition, and the bolt of a fixing collar is reliably tightened. If the battery was removed from the pallet (address the materials of the Section Removal and installation of the rechargeable battery describing the procedure of removal and installation), track that in installation time on it details or other foreign objects did not lie. At a latching of a fixing collar do not tighten its bolt too hardly.
5. Corrosion traces from the pallet, the case of the battery and surrounding surfaces can be removed by means of water solution of baking soda. Apply mix with a small brush, let's it stand and then wash away plentiful amount of clear water.
6. The metal surfaces of the car which underwent corrosion should be covered with primer on a zinc basis and then to paint.

Charging

Producers recommend to remove the battery from the car for its charging since the gas which is emitted during this procedure can damage the painted surfaces or an interior of the car, depending on a battery arrangement. Bystry charging with the connected wires of the battery can lead to damages of electric system of the car.


 PERFORMANCE ORDER

1. Remove all covers from battery cans (if they are available) and close openings pure rags to prevent an electrolyte spillage. Disconnect a negative wire of the battery and connect charger wires to its plugs (positive to positive, negative to negative), then turn on the charger in network. If it has the switch, make sure that it is installed in situation "12 volts".

If the radio receiver of your car is equipped with system of protection against theft, make sure that you gathered the correct code before a battery detachment.

2. If you use the charger with current more than two amperes, regularly check the battery during charging to make sure that it did not overheat. Using the slow charger, you can quietly leave the battery to be loaded on all night long after regular check within the first two hours. When charging batteries, not demanding leaving, certain precautionary measures can be required (for example, use very much of the low-ampere charger). On such battery can be precautionary шильдик, but if it is absent, address for consultation in dealer office of BMW or the electrician from auto repair shop.
3. If banks of the battery have removable covers, each hour within the last several hours of a charging cycle check electrolyte density by means of the areometer. Inexpensive areometers are available on sale in shops of auto parts - at their application follow the enclosed instructions. The battery can be considered loaded if within two hours indicators of density of its electrolyte do not change, and electrolyte in banks freely bubbles. Electrolyte density in separate banks has to be almost identical. If this not so, so one or several cans of the battery failed and they should be replaced.
4. Some batteries which are not demanding leaving have above the built-in areometer having a window - the color indicator of extent of battery charging. Usually brightly painted window means that the battery is completely charged, and dark color testifies to need of additional charging. More exact instructions are provided in the instruction of the manufacturer of the battery.
5. If the battery is sealed and has no built-in areometer, you can check charging degree by means of the digital voltmeter connected to plugs of the battery. Completely charged battery will show 12.6 and more than a volts.

Fuller information on the battery and on start of the engine from an auxiliary source can be found in the Head Elektrooborudovaniye of the engine and in Introduction.

Replacement of a battery brelka of remote control

 PERFORMANCE ORDER

1. Replace the battery if on the indicator of self-diagnostics the message "Funkschluessel-Batt appears." (Radio key battery)

Remote control has to be initialized if replacement of the battery lasted more than one minute, address materials below.

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

4. Replace the battery with the battery of the same type (CR1220 type). At the same time observe polarity. Install the battery in too situation, as old.
5. Fix a cover by screws, record a casing.
6. If necessary initialize remote control

 

Initialization of the transmitter

After replacement of batteries the transmitter of remote radio control has to be newly initialized (in it, however, there is no need if replacement took no more than a minute and at the same time any button was not pressed). Told treats the new transmitter (for example if old breaks).

Operation is carried out in the following order.

 PERFORMANCE ORDER

1. Take the wheel and close behind yourself a door
2. Having inserted a key into the ignition lock, for a while (at most for 5 seconds) turn it in situation 1, and then turn in situation 0
3. Take a key from the lock, press and hold the button 1 on the transmitter. Within 10 seconds execute three consecutive short-term pressing the button 2, without releasing, however, at the same time the button 1
4. Release the button 1
5. Operation of the uniform lock on locking with the subsequent immediate unlocking will be a signal of successful initialization of the transmitter

If does not follow reaction of the uniform lock, then process of initialization needs to be repeated.

If you have several transmitters, then all of them (no more than four) are also subject to initialization within 30 seconds everyone. At the same time you do not make manipulations with a key in the ignition lock.

At malfunctions address on CTOA BMW where it is possible to buy spare transmitters.

Do not allow unauthorized use of the DU panel, transferring it, for example, to the employee of parking in hotel. For this purpose use only a key 3 from a door and the lock of ignition or a spare key.
