The two batteries are located behind
the side trim panels in the luggage
compartment. There is a positive ter-
minal connection in the engine com-
partment, to which a jump-start lead
can be attached if necessary (see
Page 110).
The batteries are maintenance-free to
German DIN 43539/2 standard, that is
to say their acid content normally lasts
for the lifetime of the battery.
If the acid level drops too low, for
instance if the car is used for lengthy
periods in a hot climate, top up with
distilled water (not acid).
Acid level: up to the MAX mark on the
outside of the battery in each cell
(app. 5mm above the tops of the
plates of the cells).
Keep the tops of the batteries clean
and dry.
a
Never disconnect one of the
batteries only. Before removing, either
detach the negative terminals at both
batteries or their common earth
(ground) strap at the body (see
arrow).
c
Before taking off the right-hand lug-
gage compartment side trim, separate
the plug connector for the manual fuel
filler flap release at the cable (arrow).
