Keep away from fire and naked flames. Do not
lean over the battery. Never charge the battery
if it is still fitted to the vehicle, unless you are
using a battery charger that has been tested and
approved by Mercedes-Benz. A battery charger
unit specially adapted for Mercedes-Benz vehi-
cles and tested and approved by Mercedes-
Benz is available as an accessory. This device
permits charging of the battery while it is instal-
led. Contact a Mercedes-Benz Service Centre
for information and availability. Read the battery
charger's operating instructions before charg-
ing the battery.
All vehicles except vehicles with a lithium-
ion battery: if the warning and indicator lamps
on the instrument cluster do not light up at low
temperatures, it is very likely that the dis-
charged battery has frozen. In this case, you
may neither jump-start the vehicle nor charge
the battery. The service life of a battery that has
been thawed may be reduced. The starting char-
acteristics may be impaired, especially at low
temperatures. Have the thawed battery
checked at a qualified specialist workshop.
Vehicles with a lithium-ion battery: at low
temperatures, do not use a battery charger to
charge a battery that has been removed. Allow
the battery to warm up gently first, if necessary.
Otherwise, the service life may be reduced and
the starting characteristics impaired, especially
at low temperatures.
Jump-starting
For the jump-starting procedure, use only the jump-starting connection point, consisting of a pos-
itive terminal and an earth point, in the engine compartment.
