cialist workshop or a special
collection point for used bat-
teries.
Observe the following notes:
R Have the condition of charge checked for
the batteries more frequently if you use the
vehicle mainly for short trips or if you leave
it parked for an extended period.
In order for the batteries to achieve their
maximum possible service life, they must
always be sufficiently charged.
R When replacing a battery, only use batter-
ies that are recommended for use in
Sprinter vehicles.
R Have the battery removed at a qualified
specialist workshop.
R If you intend to leave your vehicle parked
for a long period:
- consult a qualified specialist workshop
or
- switch off the electrical system using the
battery main switch (Y page 136).
i When you park the vehicle, remove the
key if you do not require any electrical con-
sumers. The vehicle will then use very little
energy, thus conserving battery power. Installation locations
