Depending onthe engine, theoildipstick maybe
in adifferent location.
When checkingthe oillevel:
R park thevehicle onalevel surface
R the engine shouldbeswitched offfor approx-

Only
replace abattery withabattery thathas
been recommended byMercedes-Benz .
Remove theSmartKey ifyou park thevehicle
and donot require anyelectrical consumers.
The vehicle willthen usevery little energy, thus
conserving batterypower.
If the power supply hasbeen interrupted, e.g.if
you reconnec tthe battery, youwillhave to:
R set the clock using themultimedia system
(see theDigital Operator's Manual)
R reset thefunction forfolding theexterior mir-
rors in/out automaticall y,by folding themir-
rors outonce (Ypage 98) Charging

WARNING
During charging andjump-startin g,explosive
gases canescape fromthebattery. Thereisa
risk ofan explosion.
Particularl yavoid fire,open flames, creating
sparks andsmoking. Ensurethereissufficient
ventilation whilecharging andjump-startin g.
Do not lean over abattery. G
WARNING
Battery acidiscaustic. Thereisarisk ofinjury.
Avoid contactwith skin, eyesorclothing. Do
not inhale anybattery gases.Donot lean over
the battery. Keepchildren awayfrom batter-
ies. Wash awaybattery acidimmediately with
plenty ofclean water andseek medical atten-
tion. G
WARNING
A discharged batterycanfreeze attempera-
tures below freezing point.Whenjump-start-
ing the vehicle orcharging thebattery, gases
can escape fromthebattery. Thereisarisk of
an explosion.
Allow thefrozen battery tothaw outbefore
charging itor jump-startin g.
! Only
usebattery chargers withamaximum
charging voltageof14.8 V.
! Only
charge thebattery usingthejump-
starting connectionpoint. The
jump-startin gconnec tionpoint isin the
engine compartment (Ypage 282).
X Open thehood.
X Connect thebattery charger tothe positive
