Electrical System
Fuses
The fuse box (1) is accommodated
in the R-H side floor space.
A table in the fuse box cover (2)
depicts all the protected electrical
units.
Fuses must not be repaired or
bridged.
Spare fuses for emergencies
(observe amperage and color) are
stored with the tools.
Diagnose the cause of a short cir­
cuit before replacing a burned-out
fuse.
Battery
The battery is located in the trunk.
Check fluid level in each cell
approximately every four weeks,
and more frequently during the
summer and in hot climates.
Refill battery only with distilled
water. Do not use metal funnels nor
push through the overfill-protection
diaphragms in filler holes.
The battery is completely filled
when the water stops draining
through the overfill-protection
diaphragm.
To check the battery charge with a
hydrometer, push its tip through
the overfill-protection diaphragm
and take the electrolyte sample.
Coat battery terminal clamps with
acidproof grease. Keep battery
clean and dry.
Only tow vehicle with the battery
connected.
Only charge battery with a battery
charger when it is disconnected
from the vehicle electrical circuit.
Caution:
While the engine is running the bat­
tery terminal clamps must not be
loosened or detached as otherwise
the alternator and other electronic
units would be damaged.
Spark Plugs
This vehicle is equipped with spark
plugs as required for driving in the
USA. Should additional information
be necessary, your MERCEDES-
BENZ dealer will be happy to offer
advice.
