little energy, thus conserving battery

WARNING

During charging and jump-starting, explosive

gases can escape from the battery. There is a

risk of an explosion.
Particularly avoid fire, open 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 inhale any battery gases. Do not lean

over the battery. Keep children away from

batteries. Wash battery acid immediately with

water and seek medical attention.

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.

!

Only use battery chargers with a maxi-

mum charging voltage of 14.8 V.

!

Only charge the battery using the jump-

starting connection point.

The jump-starting connection point is in the

engine compartment (

Open the hood.

Connect the battery charger to the positive

order as when connecting the donor bat-

tery in the jump-starting procedure

(

page 353).

If, at low temperatures, the indicator lamps/

warning lamps in the instrument cluster do

not light up, it is highly likely that the dis-

charged battery has frozen. In this case, you

may neither charge the battery nor jump-start

the vehicle. The service life of a thawed-out

battery may be shorter. The starting charac-

teristics may be impaired, especially at low

temperatures. Have the thawed-out battery

checked at a qualified specialist workshop.
Never charge a battery still installed in the

vehicle unless a battery charger unit

approved by Mercedes-Benz is being used. A

battery charger unit specially adapted for

Mercedes-Benz vehicles and tested and

approved by Mercedes-Benz is available as an

accessory. It permits the charging of the bat-

tery in its installed position. Contact an

authorized Mercedes-Benz Center for further

information and availability. Read the battery

charger's operating instructions before

charging the battery.
