engine MERCEDES-BENZ E-CLASS SALOON 2015 Owners Manual

Observe the service intervals in the Service
Booklet or contact aqualified specialist
workshop for more information.
! You should have all work involving the
battery carried out at aqualified 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. You
can then no longer move the vehicle.
The battery and the cover of the positive
terminal clamp must be fitted securely dur- ing operation.
Comply with safety precautions and take pro-
tective measures when handling batteries. WARNING
Fire, naked flames and smoking
are prohibited when handling the
battery. Avoid creating sparks.
Battery acid is caustic. Avoid con-
tact with the skin, eyes or clothing.
Wear suitablep rotective clothing,
in particularg loves, an apron and a
face mask.
Immediately rinse acid splashes
off with clean water. Consult adoc-
tor if necessary. Wear eye protection.
Keep children away.
Observe this Owner's Manual.
HYBRID vehicles: make sure that you read
the "HYBRID" Supplement included in the
vehicle literature. You could otherwise fail to
recognise dangers, e.g. due to high voltage.
For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which have been tested and approved for your vehicle by
Mercedes-Benz.T hese batteries provide
increased impact protection to prevent vehi-
cle occupants from suffering acid burns
should the battery be damagedint he event of
an accident.
In order for the battery to achieve the maxi-
mum possibles ervice 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 such cases, have the battery dis-
connected at aqualified specialist workshop.
You can also charge the battery with a
charger recommended by Mercedes-Benz.
For more information, pleasec ontactaquali-
fied specialist workshop.
Have the battery charge checked more fre-
quently if you use the vehicle mainly for short
trips or if you leave it standing idle for a
lengthy period. Consult aqualified specialist
workshop if you wish to leave your vehicle
parked up for along period of time.
i When you park the vehicle, remove the
key if you do not require any electrical con-
sumers. The vehicle will then use very little energy, thus conserving battery power. Battery (vehicle)

Jump-starting
For the jump-starting procedure, use only the jump-starting connection point, consisting of a positive terminal and an earth point, in the engine compartment. G
WARNING
Battery acid is caustic. There is arisk 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. G
WARNING
During charging and jump-starting, explosive gases can escape from the battery. There is arisk
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 abattery. G
WARNING
During the charging process, abattery produces hydrogen gas. If ashort circuit occurs or sparks
are created, the hydrogen gas can ignite. There is arisk of an explosion.
R Make sure that the positive terminal of aconnected battery does not come into contact with
vehicle parts.
R Never place metal objects or tools on abattery.
R It is important that you observe the described order of the battery terminals when connecting
and disconnecting abattery.
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 disconnecting
the jump leads.
R Never connect or disconnectt he battery terminals while the engine is running.G
WARNING
Ad ischarged 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 arisk of an explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
! Vehicles with
apetrol engine: avoid repeated and lengthy startinga ttempts. Otherwise,
the non-combusted fuel may damage the catalytic converter.
HYBRID vehicles: make sure that you read the "HYBRID" Supplement included in the vehicle
literature. You could otherwise fail to recognise dangers, e.g. due to high voltage. Jump-starting

Important safet
ynotes G
WARNING
If you manipulate, bridge or replace afaulty
fuse with afuse of ahigher amperage, the
electric cables could be overloaded. This may result in afire. There is arisk of an accident
and injury.
Always replace faulty fuses with specified new fuses of the correct amperage.
! Only use fuses that have been approved
for Mercedes-Benz vehicles and which
have the correct fuse ratin gfor the system
concerned. Otherwise, components or sys-
tem scould be damaged.
The fuses in your vehicle serv etodisconnect
faulty circuits. If afuse blows, all the compo-
nents on the circuit and their function swill
fail.
Blown fuses must be replaced with fuses of
the same rating, which you can recognise by
the colour and fuse rating. The fuse ratings
are listed in the fuse allocation chart.
If the newly inserted fuse also blows, have the
cause traced and rectified at aqualified spe-
cialist workshop, e.g. aMercedes-Benz Ser-
vice Centre. Befor

WARNING
If RF transmitter sare tampered with or not

WARNING
If you operate RF transmitter sincorrectly in
the vehicle, the electromagnetic radiation
could interfer ewith the vehicle electronics,
e.g.:
R if the RF transmitter is not connected to an
exterior aerial
R the exterior aerial has been fitted incor-
rectly or is not alow-reflection type
This could jeopardis ethe operatin gsafet yof
