376 Practical advice
Battery
!Switch offthe engine and remove thekey
before you loose nor disconnect the terminal
clamps from the batter y.You may otherwise de-
st roy electronic components, e.g. the alternator.
Have the starter batter yche cked and, ifneces-
sary, replaced every two years or at least every
20,000 km ata qualified specialist workshop,
e.g. a Merce des-Be nz Service Centre. The battery
islocated in the engine com-
partment on the right-hand side, when
vi ewed inthe direction of travel, on the
front bulk head and under the fil ter bo x.

Risk of inju ry For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which
have bee
nsp ecially tested and approved for
your vehicl eby Mercedes-Benz. These bat-
teries are more impact-re sistant so that oc-
cup ants do not suffer acid burns if a battery
is damaged in the event of an accident.
To prevent acid burn sand scald ing, you
must obse rve the following safety precau-
tions wh enhandling batteries:
! Do not lean over the battery.
! Do not place any metal objects on the
battery. You could otherwise cause a
short circuit and the highly explosive gas
mixture in the battery could ignite.
! Make sure that you do not become elec-
trostatically charged, e.g. by wearing
synthetic clothing or due to friction be-
tween fabric s.Do not therefore pull or
pu sh the battery over carpete dfloors or
other synthetic materials. !
Do not touch the battery under any ci r-
cums tances. To eliminate any electro-
static charge, first get out of the vehicle
and touch the bodywork.
! Do not rub the batt ery with a cloth. The
battery could explode due to electro-
static charging when you touch the bat-
tery or even by sparks ar cing between
you and the battery.
