12 00 ... Instructions on starting aid
Do not start the engine with help of starting sprays.
Preparation
Conform with the following when starting engine with starting cable.
- Ensure that jump lead wires are to appropriate cross-section size.
- Only use fuse-protected jump leads.
- Check whether the current supplying battery has 12 V voltage.
- If engine is started from battery of another vehicle, ensure that there is no contact between the bodies of both vehicles.
| CAUTION | Never touch ignition system components and current - dangerous high tension! |
If the battery in the vehicle supplying power is weak, start the engine of this vehicle and let it run at idling speed.
Carrying out
Always conform with the procedures to avoid injury to persons or damage to parts.
- On automatic transmission, select "P" setting, apply handbrake.
- Move the shift lever of vehicles with manual transmission into neutral and apply the parking brake.
- Ensure that the jump leads cannot get caught in rotating parts, e.g. fan.
- First connect positive terminals of both batteries with one jump lead (red).
- Use positive connection point in engine compartment for vehicles with one battery in trunk.
- Then attach second jump lead (black) to negative terminal of donor battery and to engine ground or body ground on vehicle to be started.
| CAUTION | Never connect second jump lead (black) to negative terminal of battery in vehicle to be started. This would produce explosive gas which could be ignited by sparks. |
Danger of explosion!
After engine of vehicle to be started has started up, first disconnect the jump lead on the negative terminal/ground connection. Then remove jump lead from positive terminals.

Battery care and maintenance
In low-maintenance batteries, check the acid level at least once a year. If necessary, top up with distilled water up to the top marking.
The increasing number of electronic control units in the car reduces the self-discharging time of the battery (even in standby mode). To maintain the battery service life and to avoid exhaustive discharging, recharge laid-up vehicles every 6 weeks at the latest (refer to battery recharging schedule here, SI 6 10 398 387). The time for self-discharging depends on vehicle type and equipment specification.
Battery test
The battery acid density can be used to measure the charge state. However this test produces uncertainty caused by a design-related range of variation. The acid density e.g. for a charged battery is 1.28 kg/l (in the tropical version the acid density is 1.23 kg/l).
Another interference factor is the acid lamination immediately after filling with distilled water.
Battery wear with partially sulfated and/or heavily contaminated plates will also lead to incorrect acid density test results.
61 00 ... BATTERY CHARGING
If a normal or quick charger is used to charge the battery, the battery must be disconnected from the vehicle electrical system and removed. This prevents damage to paintwork and upholstery.
Ideally, battery charging is performed with BMW-approved charging computers, refer to
SI 2 03 98 350 and
SI 2 06 02 854.
| IMPORTANT | In order to prevent the intelligent battery sensor from malfunctioning, the charging terminals in the engine compartment must be used without fail in vehicles from E60 and should be used if possible in other vehicles. |
| IMPORTANT | Before charging the battery while it is installed, first carry out a closed-circuit current test. Refer to 61 20 ... BATTERY OPEN-CIRCUIT CURRENT TEST . If here the voltage is 10 V or less, one or more of the cells may be faulty or the entire battery may already be damaged. In this case, always remove the battery as escaping gases during charging could damage the interior equipment and trim. Attempt to regenerate faulty cells with low charging current. |
If necessary, open existing plugs on the individual cells.
61 00 ... Safety instructions for handling vehicle battery
Battery acid is highly corrosive
Do not allow any battery acid to come into contact with the eyes, the skin or clothing. Therefore wear protective clothing, gloves and goggles.
Do not tilt the battery, acid may emerge from the vent opening.
In event of contact with acid
If acid is splashed into the eyes, rinse them immediately for several minutes with clear water. You must then consult a doctor without delay.
If acid is splashed onto the skin or clothing, neutralize it immediately with a soapy solution and rinse with lots of water.
Seek medical attention immediately if battery acid is accidentally swallowed.
Explosion hazard
Strictly no flames, sparks, naked light or smoking!
A highly explosive mixture of electrolytic gas is created when batteries are charged. The rooms where charging is carried out must therefore always be well ventilated.
Avoid the formation of sparks when handling cables, wiring and electrical devices.
Turn the ignition lock to the 0 position before disconnecting or connecting the battery.
Do not place tools or any similar object on the battery (danger of short-circuiting and explosion!).

12 00... Instructions for disconnecting and connecting battery
Observe safety instructions for handling vehicle battery. Refer to 61 00 ... SAFETY INSTRUCTIONS FOR HANDLING VEHICLE BATTERY .
Before disconnecting battery
Switch off ignition.
Note. If the ignition is not turned off when the battery is disconnected, fault memories may be set in some control units.
| IMPORTANT | There is a danger of mixing up battery leads: If the battery positive and negative leads are the same color and you are in doubt, follow the polarity to the battery, then mark and cover the leads. On vehicles with radio code: After disconnecting the battery, the radio code must be re-entered. Therefore obtain the radio code card from the customer beforehand. Note stored stations and restore them after connecting the battery. Stored settings of the on-board computer and clock will also be lost. All available central keys must be recoded for cars with first generation infrared transmitter locking systems. |
General notes on disconnecting battery
- Do not disconnect battery leads and leads from alternator and starter motor while engine is running.
- Cars with IBS on battery negative terminal: Do not under any circumstances pull/lever off pole shoes by force. Do not under any circumstances release socket-head cap screw of IBS.
- Detach terminal of battery negative lead from car battery and second battery if fitted. Cover battery negative terminal(s) and secure.
- When work is carried out on the electrical system, faults may be caused in the fault memories of some control units when the battery is connected.
- When fitting terminal for battery negative lead: Tightening torque 61 21 1 AZ. Refer to «GENERAL ELECTRICAL SYSTEM - TIGHTENING TORQUES»(/bmw/m3/e46-1999-2006/remont/horns/#general-electrical-system-tightening-torques) .
After connecting battery
| IMPORTANT | After a power supply interruption some equipment is disabled and must be reactivated. Likewise, individual settings are lost and must be activated. Example: Activate sliding sunroof, refer to 54 0 NOTES ON STEEL AND GLASS SLIDE/TILT SUNROOFS (INITIALIZATION/NORMALIZATION/LEARNING OF CHARACTERISTIC CURVE) Vehicles with AFS only: Activate steering angle If necessary, activate power windows If necessary, activate mirror with compass |
Vehicles with a two-battery system
Starter and equipment batteries
A two-battery system has a starter battery circuit and an equipment battery circuit. A secondary control unit monitors both battery circuits. Depending on the situation, the battery circuits are connected to or isolated from the secondary control unit via an isolating relay.
| IMPORTANT | These batteries must not under any circumstances be charged with a voltage in excess of 14.8 V. Rapid programs must not be used either. |
Receiving/giving starting assistance via jump start terminal
The engine can be jump-started with an external voltage supply via the jump start terminal on the right side of the engine compartment.
Note. The starter battery is isolated from the alternators when the engine hood/bonnet is open.
Giving starting assistance via the jump start terminal is thus limited by the capacity of the starter battery when the engine hood/bonnet is open.
Charging starter and equipment batteries via jump start terminal
The starter battery is charged as a matter of priority with a charger connected to the jump start terminal. The voltage at the starter battery is the decisive factor in determining whether the equipment battery is also included in the charging operation. The secondary control unit automatically detects a charging operation at a charging voltage at the starter battery of graterthenequale ace; 13.5 V. The isolating relay is closed and thus the equipment battery is connected in parallel. Both batteries are now charged.
Prerequisite
- Terminal 61 inactive
- Terminal 15 inactive
If terminal 15 becomes "active" during the charging operation, the isolating relay is opened immediately and again only the starter battery is charged.
Note. When the engine hood is open, the isolating relay is also opened in normal operation when the engine is running. A special mode can be set by means of diagnosis for workshop/garage operation. The isolating relay is closed from terminal R in this operating mode. This mode is automatically reset once a distance of 5 km has been driven.
Trickle charging
Increased closed-circuit current consumption can be compensated with the aid of the battery trickle charger (special tool 61 2 410) via the jump start terminal.
| IMPORTANT | The cigarette lighter is isolated from the electrical system after terminal R "OFF" on a timed basis (60 mins.), thereby interrupting charging of the equipment battery via the cigarette lighter. This is prevented if the battery master switch (on the right side of the luggage compartment behind the panel) is turned on and off again twice within 2 seconds. (Cigarette light battery charging function). |
Do not start the engine with help of starting sprays.
Preparation
Conform with the following when starting engine with starting cable.
- Ensure that jump lead wires are to appropriate cross-section size.
- Only use fuse-protected jump leads.
- Check whether the current supplying battery has 12 V voltage.
- If engine is started from battery of another vehicle, ensure that there is no contact between the bodies of both vehicles.
| CAUTION | Never touch ignition system components and current - dangerous high tension! |
If the battery in the vehicle supplying power is weak, start the engine of this vehicle and let it run at idling speed.
Carrying out
Always conform with the procedures to avoid injury to persons or damage to parts.
- On automatic transmission, select "P" setting, apply handbrake.
- Move the shift lever of vehicles with manual transmission into neutral and apply the parking brake.
- Ensure that the jump leads cannot get caught in rotating parts, e.g. fan.
- First connect positive terminals of both batteries with one jump lead (red).
- Use positive connection point in engine compartment for vehicles with one battery in trunk.
- Then attach second jump lead (black) to negative terminal of donor battery and to engine ground or body ground on vehicle to be started.
| CAUTION | Never connect second jump lead (black) to negative terminal of battery in vehicle to be started. This would produce explosive gas which could be ignited by sparks. |
Danger of explosion!

Battery acid is highly corrosive
Do not allow any battery acid to come into contact with the eyes, the skin or clothing. Therefore wear protective clothing, gloves and goggles.
Do not tilt the battery, acid may emerge from the vent opening.
In event of contact with acid
If acid is splashed into the eyes, rinse them immediately for several minutes with clear water. You must then consult a doctor without delay.
If acid is splashed onto the skin or clothing, neutralize it immediately with a soapy solution and rinse with lots of water.
Seek medical attention immediately if battery acid is accidentally swallowed.
Explosion hazard
Strictly no flames, sparks, naked light or smoking!
A highly explosive mixture of electrolytic gas is created when batteries are charged. The rooms where charging is carried out must therefore always be well ventilated.
Avoid the formation of sparks when handling cables, wiring and electrical devices.
Turn the ignition lock to the 0 position before disconnecting or connecting the battery.
Do not place tools or any similar object on the battery (danger of short-circuiting and explosion!).
