Checking and refilling levels
only be replaced with a battery of the same
specifications.
Y
our vehicle is equipped with an intelligent
power management system to control the
distribution of electrical energy

page 342.
The power management function ensures
that the battery is charged much more effi-
ciently than on vehicles without a power
management system. To maintain this func-
tion after replacing the battery, we recom-
mend that the replacement battery used is of
the same make and type as the original fitted
battery. To make proper use of the power
management function after the battery has
been changed, have the battery coded to the
power management mode at a specialised
workshop.
