HEnvironmental note
Batteries contain dangerous
substances. It is against the
law to dispose of them with
the household rubbish. They
must be collected separatelyand recycled to protect the
environment.
Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries to a qualified spe-
cialist workshop or a special
collection point for used bat-
teries.
In order for the battery to achieve the maximum
possible service life, it must always be suffi-
ciently charged.
Comply with safety precautions and take pro-
tective measures when handling batteries.
Risk of explosion.
Fire, open flames and smoking are
prohibited when handling the bat-
tery. Avoid creating sparks.
Battery acid is caustic.
Avoid contact with skin, eyes or
clothing.
Wear eye protection.
Keep children away.
Observe this Operator's Manual.
The vehicle battery, like other batteries, can dis-
charge over time if you do not use the vehicle. In
this case, have the battery disconnected at a
qualified specialist workshop. You can also
charge the battery with a charger recommended by Mercedes-Benz. Contact a qualified special-
ist workshop for further information.
For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz. These batteries provide
increased impact protection to prevent vehicle
occupants from suffering acid burns should the
battery be damaged in the event of an accident.
Have the battery condition of charge checked
more frequently if you use the vehicle mainly for
short trips or if you leave it standing idle for a
lengthy period. Consult a qualified specialist
workshop if you wish to leave your vehicle
parked for a long period of time.
iRemove the SmartKey if you park the vehi-
cle and do not require any electrical consum-
ers. The vehicle will then use very little energy,
thus conserving battery power.
iIf the power supply has been interrupted,
e.g. due to a discharged battery, you will have
to:
Rset the clock. Information on setting the
clock can be found in the separate operat-
ing instructions.
On vehicles with COMAND and a navigation
system, the clock is set automatically.
Rreset the head restraints on the front seats
(Ypage 75)
Rreset the function for folding the exterior
mirrors in/out automatically, by folding the
mirrors out once (
Ypage 81).
