vehicle literature. You could otherwise fail to

recognize dangers e.g. due to high voltage.

For safety reasons, Mercedes-Benz

recommends that you only use batteries

which 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 must always

be sufficiently charged.

The vehicle battery, like other batteries, can

discharge over time if you do not use the

vehicle. In this case, have the battery

disconnected at a qualified specialist

workshop. You can also charge the battery

with a charger recommended by Mercedes-

Benz. Contact a qualified specialist workshop

for further information.

Have the battery condition of charge checked

more frequently if you use the vehicle mainly

for short trips or if you leave it standing idle

for a lengthy period. Consult a qualified

specialist workshop if you wish to leave your

vehicle parked for a long period of time.

i

Remove the SmartKey if you park the

vehicle and do not require any electrical

consumers. The vehicle will then use very

little energy, thus conserving battery

power.

i If the power supply has been interrupted,

e.g. if you reconnect the battery, you will

have to:

R

set the clock. Information on setting the

clock can be found in the separate

operating instructions.

On vehicles with COMAND and a

navigation system, the clock is set

automatically.

R

reset the function for folding the exterior

mirrors in/out automatically, by folding

the mirrors out once (Y page 123).

WARNING

A discharged battery can freeze at

temperatures below freezing point. When

jump-starting 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

maximum 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 (Y page 362).

X

Open the hood.

X

Connect the battery charger to the positive

terminal and ground point in the same

order as when connecting the donor

battery in the jump-starting procedure

(Y page 362).

If, at low temperatures, the indicator lamps/

warning lamps in the instrument cluster do

not light up, it is highly likely that the

discharged battery has frozen. In this case,

you may neither charge the battery nor jump-
