Battery care

The battery is absolutely maintenance-

free, that is, the original electrolyte will

normally last for the service life of the

battery under moderate climatic condi-

tions.

For all questions that regard the

battery, please consult your BMW

center. Since the battery is mainte-

nance-free, the following is for your

information only.<

Symbols

You will find the following symbols on

your car battery. To avoid injury, please

comply with the corresponding precau-

tions whenever you work with or near

the battery.

Before handling the battery,

please read the following infor-

mation.

Wear eye protection. Do not

allow particles containing bat-

tery acid or lead to come into

contact with your eyes, your skin, or

your clothing.

Battery acid is extremely corro-

sive. Wear eye protection and

protective gloves. Do not tip the

battery. Battery acid can leak from the

ventilation openings.

Do not allow children access to

batteries and battery acid.

Never allow sparks or open

flame in the vicinity of the bat-

tery. Avoid sparks from electri-

cal cables or electrical equipment. Turn

the key to position 0 in the steering lock

when disconnecting or connecting the

battery. Do not short-circuit the battery

terminals. This creates a risk of injury

from high-energy sparks.

A highly-explosive gas is gener-

ated when the battery is charged.

If battery acid is splashed into

your eyes, rinse them thor-

oughly with clear water for at

least 15 minutes. Consult a physician

immediately. If your skin or clothing are

splashed by acid, rinse immediately

with ample clear water. If electrolyte is

accidentally swallowed, consult a phy-

sician immediately.

In order to protect the battery

case from ultraviolet radiation,

do not place it in direct sunlight.

A discharged battery can freeze. Store

the battery in areas where temperature

remains above freezing.

Removal and installation

Do not disconnect the battery

when the engine is running. If you

do so, the ensuing voltage surge will

damage the vehicle's onboard electron-

ics.

Do not make any modifications in the

wires to the positive terminal. If you do

so, the protective function of the safety

battery terminal is no longer ensured.

Repair and disposal must be performed

by trained technicians only.<

When removing the battery, disconnect

the cable on the negative terminal first,

then the cable on the positive terminal.

Loosen the center adjusting screw on

the battery retaining strap (use the

screwdriver included with the onboard

tool kit) and disconnect the strap.

When installing a battery, connect the

positive terminal first, then connect the

negative terminal.

When installing a battery, be sure

that it is mounted properly and

that the retaining bracket is installed

with the center adjustment screw. If this

is not done, the battery will not be ade-

quately secured in case of an acci-

dent.<
