ment cluster fails to come on during the bulb self-check when switching on the
ignition, have the respective bulb checked
and replaced if necessary.

running.ABS has detected a malfunction and has
switched off. The BAS and the ESP® are also
switched off (see messages in multifunction

Battery
Connect the positive lead to the posi-
tive terminal and fasten it’s cover
(
page 509).
Connect the negative lead to the nega-
tive terminal (

lead. Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.
!Never invert the terminal connections!
iThe following procedures must be carried
out following any interruption of battery power
(e.g. due to disconnection):

Set the clock (page 176).
