storing the wheel and tools.

sible and have the new wheel balanced.

Maintenance
The battery needs no routine maintenance
whatsoever, in other words the quantity of acid
it contains will normally last for the full operating
life of the battery in temperate climates. BMW
Service will gladly advise you on all matters
relating to batteries.

Recharging the battery

Recharge the battery only with the engine
stopped, via the connections in the engine
compartment. Connections, see Starting with a
flat battery on page 236.
Battery switch
If the car is to remain out of use for several
weeks, push the battery switch behind the
right-hand side trim in the luggage compart-
ment to the OFF position. This reduces current
consumption while the car is out of use. A mes-
sage appears on the info display. Observe the
supplementary information on the control dis-
play.
