WARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery, gases
can escape from the battery. There is a risk of
an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
If the indicator/warning lamps do not light up in
the instrument cluster when temperatures are
low, it is probably because the discharged bat-
tery has frozen. Should this be the case, do not
jump-start the vehicle or charge the battery. The
service life of a thawed battery may be shorter.
Start-up behaviour may deteriorate, particularly
at low temperatures. Have the thawed battery
checked at a qualified specialist workshop.
G
WARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a
risk of an explosion.
Particularly avoid fire, naked flames, creating
sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting.
Do not lean over a battery.
G
WARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with the skin, eyes or clothing.
Do not breathe in any battery gases. Do not
lean over the battery. Keep the batteries out
of the reach of children. Immediately rinse off
battery acid thoroughly with plenty of clean
water and seek medical attention at once.
!
Only charge the fitted battery with a battery
charger that has been tested and approved by
Mercedes-Benz. This device allows the bat-
tery to be charged when it is fitted in the vehi-
cle. The vehicle's electronics system may oth-
erwise be damaged.
! Only charge the battery using the jump-start
connection point.
A battery charger unit specially adapted for
Mercedes-Benz vehicles and tested and
approved by Mercedes-Benz is available as an
accessory. Only this device permits the charging
of the battery in its installed position. Contact a
Mercedes-Benz Service Centre for information
and availability. Read the operating instructions
for your charger before charging the battery.
Recharge the battery more frequently if you use
the vehicle mainly for short trips and/or drive at
low outside temperatures.
Only charge the fitted battery with a battery
charger that has been tested and approved by
Mercedes-Benz, using the jump-start connec-
tion point in the engine compartment.
X
Connect the battery charger to the positive
terminal and earth terminal in the same order
as when connecting the donor battery in the
jump-starting procedure (
Y
page 358).
i If a battery is not fitted and not in service,
you should charge it every three months. This
helps to counteract self-discharging and pre-
vent damage to the battery.
Care
! Dirty battery terminals and battery surfaces
cause creepage current. This can cause the
batteries to discharge.
! Do not use any cleaning agents containing
fuel. Cleaning agents containing fuel corrode
the battery housing.
! If dirt enters the battery cell, self-discharg-
ing of the battery is increased and the battery
may be damaged.
The following points on battery care must be
observed:
X Regularly check the battery terminals and the
fastening of the negative cable to the chassis
to ensure that they are firmly seated.
X Always keep the battery terminals and battery
surfaces clean and dry.
X
Lightly grease the undersides of the battery
terminals with acid-resistant grease.
X
Only clean the battery casing with a commer-
cially available cleaning product.
