Important safety notes
G WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system or exhaust
gas flow. There is a risk of fire.
Park the vehicle so that no flammable mate-
rials come into contact with parts of the vehi-
cle which are hot. Take particular care not to
park on dry grassland or harvested grain
fields.
G WARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example: R
release the parking brake. R
shift the automatic transmission out of the
parking position P .R
start the engine. In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
! Always secure the vehicle correctly
against rolling away. Otherwise, the vehicle
or its drivetrain could be damaged.
To ensure that the vehicle is secured against
rolling away unintentionally: R
the electric parking brake must be applied. R
the transmission must be in position P and
the transmission position display must
show P . R
the SmartKey must be removed from the

board voltage is low or there is a malfunction
in the system, it may not be possible to apply
the released parking brake. X
If this is the case, only park the vehicle on
level ground and secure it to prevent it roll-
ing away. X

tion P .
It may not be possible to release an applied
parking brake if the on-board voltage is low or
there is a malfunction in the system. Contact
a qualified specialist workshop.

Always make sure that neither you nor the
battery is electrostatically charged. A build-
up of electrostatic charge can be caused, for
example: R
by wearing clothing made from synthetic
fibers R
due to friction between clothing and seats R
if you push or pull the battery across the
carpet or other synthetic materials R
if you wipe the battery with a cloth
G WARNING
During the charging process, a battery produ-
ces hydrogen gas. If a short circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion. R
Make sure that the positive terminal of a
connected battery does not come into con-
tact with vehicle parts. R
Never place metal objects or tools on a bat-
tery. R
It is important that you observe the descri-
bed order of the battery terminals when
connecting and disconnecting a battery. R
When jump-starting, make sure that the
battery poles with identical polarity are
connected. R
It is particularly important to observe the
described order when connecting and dis-
connecting the jumper cables. R
Never connect or disconnect the battery
terminals while the engine is running.
G WARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with skin, eyes or clothing. Do
not inhale any battery gases. Do not lean over
the battery. Keep children away from batter-
ies. Wash away battery acid immediately with
plenty of clean water and seek medical atten-
tion. H Environmental note
Batteries contain dangerous
substances. It is against the
law to dispose of them with
the household rubbish. They
must be collected separately
and recycled to protect the
environment.
Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries to a qualified spe-
cialist workshop or a special
collection point for used bat-
teries.
! Have the battery checked regularly at a
qualified specialist workshop.
Observe the service intervals in the Main-
tenance Booklet or contact a qualified spe-
cialist workshop for more information.
! You should have all work involving the
battery carried out at a qualified specialist
workshop. In the exceptional case that it is
necessary for you to disconnect the battery
yourself, make sure that: R
you switch off the engine and remove the
key. On vehicles with KEYLESS-GO,
ensure that the ignition is switched off.
Check that all the indicator lamps in the
instrument cluster are off. Otherwise,
electronic components, such as the
alternator, may be damaged. R
you first remove the negative terminal
clamp and then the positive terminal
clamp. Never swap the terminal clamps.
Otherwise, the vehicle's electronic sys-
tem may be damaged. R
in vehicles with automatic transmission,
the transmission is locked in position P
after disconnecting the battery. The vehi-
cle is secured against rolling away. Yo u
ca n
then no longer move the vehicle.
The battery and the cover of the positive
terminal clamp must be installed securely
during operation.328

Comp ly wit h safety precautions and take pro-
tective measures when han dlin g batteries.
Risk of explosion.
Fire, open flames and smoking are
prohibited when handling the bat-
tery. Avoid creating sparks.
Battery acid is caustic. Avoid con-
tact wit h skin, eyes or clothing.
Wear suit able protective clothing,
especial ly gloves, apron and face-
guard.
Rins e any acid spills immediately
wit h clear water. Contact a physi-
cian if necessary.
Wear eye protection.
Keep children away.
Observe th is Operator's Manual.
For safety reasons, Mercedes-Benz recom-
men ds that you only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz. These batteries pro vide
increased impact protection to prevent veh i-
cle occupants from suffering acid burns
should the battery be damaged in the event of
an acc iden t.
In order for the battery to achieve the max i-
mum poss ible service life, it must always be
suff icie nt ly charge d.
Like other batteries, the vehicle battery may
disc harge over time if you do not use the
veh icle . In th is case, have the battery discon-
nected at a qualif ied specialist workshop. You
can also charge the battery with a charger
recommended by Mercedes-Benz. Contact a qualif ied spec ialist workshop for further infor-
mation.
Have the battery condition of charge checked
more frequently if you use the vehicle main ly
for short trips or if you leave it standing idle
for a lengthy per iod. Consult a qualif ied spe-
cialist workshop if you wish to leave your
vehicle parked for a long period of time.
On ly replace a battery with a battery that has
been recommended by Mercedes-Benz.
Remo ve the Sm artKey if you park the vehicle
and do not require any electrical consumers.
The vehicle will then use very lit tle energy,
t hus conserving battery power.
If the power supply has been interrupted, e.g.
if you reconnect the battery, you will have to:R
set the clock via Aud io 20 or COMAND (see
separate operating instructions). R
reset the function for folding the exterior
mirrors in/out automatically, by folding the
mirrors out once ( Y
