280 Practical hintsBattery
Batteries contain materials that can harm
the environment if disposed of improperly.

lead. Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.
iThe following procedures must be car-
ried out following any interruption of
battery power (e.g. due to reconnec-
tion):
Set the clock (
page 118).
Set the date in trip computer
(page 186).
Calibrate the compass
(page 188).
Resynchronize the ESP
(page 246).
Resynchronize side power windows
(page 146).
