Electrolyte or battery acid is corro-
sive. Avoid contact with the skin,
eyes and clothing.

particular, gloves, an apron and a
face mask.
Immediately rinse electrolyte or acid
splashes off with clean water. Con-
sult a doctor if necessary.

Observe this Owner's Manual.
For safety reasons, Mercedes-Benz recom-
mends that you use only batteries that 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.
In order for the battery to achieve the maximum
possible service life, it should always be suffi-
ciently charged.
Like other batteries, the vehicle battery may
discharge over time if you do not use the vehicle.
In such cases, have the battery disconnected at
a qualified specialist workshop. However, you
can also charge the battery with a charger rec-
ommended by Mercedes-Benz. For more infor-
mation, please contact a qualified specialist
workshop.
Have the battery charge checked more fre-
quently if you use the vehicle mainly for short
trips or if you leave it standing idle for an exten-
ded period. Consult a qualified specialist work-
shop if you wish to leave your vehicle parked up
for a long period of time.
When you park the vehicle, remove the key if you
do not require any electrical consumers. The
vehicle will then use very little energy, thus con-
serving battery power.
