Battery (vehicle)

Important safety notes

Special tools and expert knowledge are

required when working on the battery, e.g.

removal and installation. You should there-

fore have all work involving the battery car-

ried out at a qualified specialist workshop.

WARNING

Work carried out incorrectly on the battery

can lead, for example, to a short circuit and

thus damage the vehicle electronics. This can

lead to function restrictions applying to

safety-relevant systems, e.g. the lighting sys-

tem, ABS (anti-lock braking system) or ESP

(Electronic Stability Program). The operating

safety of your vehicle may be restricted. You

could lose control of the vehicle, for example:

braking

in the event of abrupt steering maneuver

and/or when the vehicle's speed is not

adapted to the road conditions

There is a risk of an accident.

In the event of a short circuit or a similar inci-

dent, contact a qualified specialist workshop

immediately. Do not drive any further. You

should have all work involving the battery car-

ried out at a qualified specialist workshop.

For further information about ABS and ESP

see (Y page 65) and (Y page 68).

WARNING

Electrostatic build-up can lead to the creation

of sparks, which could ignite the highly explo-

sive gases of a battery. There is a risk of an

explosion.

Before handling the battery, touch the vehicle

body to remove any existing electrostatic

build-up.

The highly flammable gas mixture forms when

charging the battery as well as when jump-

starting.

Always make sure that neither you nor the

battery is electrostatically charged. A build-

up of electrostatic charge can be caused, for

example:

by wearing clothing made from synthetic

fibers

due to friction between clothing and seats

if you push or pull the battery across the

carpet or other synthetic materials

if you wipe the battery with a cloth

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.

Make sure that the positive terminal of a

connected battery does not come into con-

tact with vehicle parts.

Never place metal objects or tools on a bat-

tery.

It is important that you observe the descri-

bed order of the battery terminals when

connecting and disconnecting a battery.

When jump-starting, make sure that the

battery poles with identical polarity are

connected.

It is particularly important to observe the

described order when connecting and dis-

connecting the jumper cables.

Never connect or disconnect the battery

terminals while the engine is running.

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.

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:

you switch off the engine and remove the

SmartKey. Check that all the indicator

lamps in the instrument cluster are off.

Otherwise, electronic components, such

as the alternator, may be damaged.

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.

on vehicles with automatic transmission,

the transmission is locked in position P

after disconnecting the battery. The vehi-

cle is secured against rolling away. You

can then no longer move the vehicle.

The battery and the cover of the positive

terminal clamp must be installed securely

during operation.

Comply with safety precautions and take pro-

tective measures when handling 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 with skin, eyes or clothing.

Wear suitable protective clothing,

especially gloves, apron and face-

guard.

Rinse any acid spills immediately

with clear water. Contact a physi-

cian if necessary.

Battery (vehicle)

Breakdown assistance

Wear eye protection.

Keep children away.

Observe this Operator's Manual.

For safety reasons, Mercedes-Benz recom-

mends 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 vehi-

cle occupants from suffering acid burns

should the battery be damaged in the event of

an accident.

In order for the battery to achieve the maxi-

mum possible service life, it must always be

sufficiently charged.

Like other batteries, the vehicle battery may

discharge over time if you do not use the

vehicle. In this case, have the battery discon-

nected 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 infor-

mation.

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 spe-

cialist workshop if you wish to leave your

vehicle parked for a long period of time.

Only replace a battery with a battery that has

been recommended by Mercedes-Benz.

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:

set the clock (audio system/COMAND,

see the separate operating instructions).

reset the function for folding the exterior

mirrors in/out automatically, by folding

the mirrors out once (Y page 104).

Charging the 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.

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 (Y page 315).

Breakdown assistance

Open the hood.

Connect the battery charger to the positive

terminal and ground point in the same

order as when connecting the donor bat-

tery in the jump-starting procedure

(Y page 315).

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 jump-start the vehicle nor charge

the battery. The service life of a thawed-out

battery may be shorter. The starting charac-

teristics can be impaired, particularly at low

temperatures. Have the thawed-out battery

checked at a qualified specialist workshop.

Only charge the installed battery with a bat-

tery charger which has been tested and

approved by Mercedes-Benz. An accessory

battery charge unit specially adapted for

Mercedes-Benz vehicles and tested and

approved by Mercedes-Benz is available. It

permits the charging of the battery in its

installed position. Contact an authorized

Mercedes-Benz Center for further informa-

tion and availability. Read the battery charg-

er's operating instructions before charging

the battery.
