GWarning!
The electrolyte, i.e. the battery fluid, is toxic
and caustic. Do not allow this fluid to come in
contact with eyes, skin or clothing, for
example in case of an accident.
In case it does, immediately flush affected
area with water and seek medical help
immediately.
For information on the location of the 12-volt
battery and the high-voltage battery, see
(Y page 13).
! Deep discharge caused by prolonged
periods of the vehicle not being used, can
damage the high-voltage battery.
During such periods, operate the vehicle
every 4 weeks for several minutes in order
to charge the high-voltage battery.
During the charging process, switch off
electrical consumers that are currently not
needed, e.g. climate control system or seat
heating.
If necessary, get a jump start.
GWarning!
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and lead to death. Do not
run the engine in confined areas (such as a
garage) which are not properly ventilated.
If you do not intend to operate your vehicle
for an extended period of time, contact an
authorized Mercedes-Benz Center about
steps you need to observe.
