oil MERCEDES-BENZ B-CLASS HATCHBACK 2015 Owners Manual

To avoid hazardous situations, observe the
following:
R Only connect the charging cable to a wall-
box:
- which has been properly installed and
- which has been inspected by a qualified
electrician
R For safety reasons, only use charging
cables that have been tested and approved
by the manufacturer for charging the high-
voltage battery in an electric vehicle.
R Never use damaged charging cables.
R Do not extend the charging cable.
R Never use adapters.
R Observe the safety notes in the operating
instructions for the wallbox.
The vehicle's high-voltage electrical system is
under high voltage.
R Do not handle high-voltage components or
the orange cables of the vehicle's high-volt-
age electrical system.
R Do not touch high-voltage components or the
orange cables of the high-voltage electrical
system when a vehicle has been involved in a
crash.
R Do not touch any damaged components or
damaged orange cables of the vehicle's high-
voltage electrical system.
R Do not remove the covers of the high-voltage
electrical system components that are
marked with a warning sticker. Notes on the charging cable
Handling the charging cable and charg-
ing cable controls Do not leave the charging cable controls
(Y page 140) hanging loose from a mains
socket. Otherwise, this could result in a poor
contact with the mains socket and malfunctions
when charging the vehicle. To ensure that the brackets within the charging
cable controls are not subjected to incorrect
loads, observe the following:
R never lift or carry the controls by the charging
cable connector or the mains plug
R to transport the charging cable, the coiled
part can be:
- wrapped around the controls or
- secured to the housing of the controls
Heat generated by the charging cable
and charging cable connector Observe the important safety notes
(Y
page 134).
During the charging process, the charging cable
and charging cable connector may heat up.
The charging cable and charging cable connec-
tor will only heat up within the permissible lim-
iting values, provided that:
R the mains power supply and the charging
cable are not damaged
R the instructions for handling the charging
cable and controls on the charging cable are
observed
Should the permissible heating temperature lim-
its be exceeded, have the mains power supply
checked.
Protection device against overvoltage !
Voltage surges in the mains supply can dam-
age the vehicle. The vehicle is therefore
equipped with a device which protects it from voltage surges in the mains supply. This
device may be triggered during severe thun-
derstorms, for example, and may lead to the
building's fuse being tripped and an interrup-
tion in the power supply. These functions pro-
tect the vehicle. After the building fuse is
switched on again, the charging process
resumes automatically. Following an interrup-
tion in the power supply without tripping of
the building's fuse, it may take up to
15 minutes for charging to resume automat-
ically.
Switch on the building's fuse again after the
protection device against overvoltage has been triggered. Otherwise, the charging process can-not be continued. The high-voltage battery will
not be charged and you may not be able to drive
the vehicle. High-voltage battery

Damaged seals or electrical components can
lead to leaks or failures.
Cleaning the paintwork !
Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
Scratches, corrosive deposits, areas affected by
corrosion and damage caused by inadequate
care cannot always be completely repaired. In
such cases, visit a qualified specialist workshop.
X Remove impurities immediately, where pos-
sible, whilst avoiding rubbing too hard.
X Soak insect remains with insect remover and
rinse off the treated areas afterwards.
X Soak bird droppings with water and rinse off
the treated areas afterwards.
X Remove coolant, brake fluid, tree resins, oils,
fuels and greases by rubbing gently with a
cloth soaked in petroleum ether or lighter
fluid.
X Use tar remover to remove tar stains.
X Use silicone remover to remove wax.
Care and treatment of matt paintwork !
Never polish the vehicle or the light alloy
wheels. Polishing makes the paintwork shiny.
! The following may cause the paint to
become shiny and thus reduce the matt
effect:
R vigorous rubbing with unsuitable materials
R frequent use of car washes
R washing the vehicle in direct sunlight
! Never use paint cleaner, buffing or polishing
products, or gloss preserver, e.g. wax. These
products are only suitable for high-gloss sur-
faces. Their use on vehicles with matt finish
leads to considerable surface damage (shiny, spotted areas).
Always have paintwork repairs carried out at a
qualified specialist workshop.
! Do not use wash programs with a hot wax
treatment under any circumstances. Observe these notes if your vehicle has a clear
matt finish. This will help you to avoid damage to
the paintwork due to incorrect treatment.
These notes also apply to light-alloy wheels witha clear matt finish.
The vehicle should preferably be washed by
hand using a soft sponge, car shampoo and
plenty of water.
Use only insect remover and car shampoo from
the range of approved Mercedes-Benz care
products. Cleaning vehicle parts
Cleaning the wheels G
WARNING
The water jet of circular-jet nozzles (dirt grind- ers) can cause damage not visible from the
outside to tyres or chassis components. Com-
ponents damaged in this way can unexpect-
edly fail. There is a risk of an accident.
Do not use high-pressure cleaners with circu-
lar-jet nozzles to clean the vehicle. Have dam- aged tyres or chassis components replaced
immediately.
! Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
! Do not park up the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after cleaning. Braking heats the brake discs and the brake
pads/linings, thus drying them. The vehicle
can then be parked up.
Cleaning the windows G
WARNING
If the windscreen wipers are set in motion
when cleaning the windscreen or wiper
blades, you could become trapped. There is a danger of injury. 244

! To retain the natural appearance of the
leather, observe the following cleaning
instructions:
R Clean genuine leather covers carefully with
a damp cloth and then wipe the covers
down with a dry cloth.
R Make sure that the leather does not
become soaked. It may otherwise become
rough and cracked.
R Only use leather care agents that have
been tested and approved by Mercedes-
Benz. You can obtain these from a qualified specialist workshop.
Leather is a natural product.
It has natural surface properties, e.g.:
R unevenness in structure
R marks caused by growth and injury
R subtle colour differences These are characteristics of leather and not
material faults.
Seat covers from other materials
! Observe the following when cleaning:
R clean artificial leather covers with a cloth
moistened with a solution containing 1%
detergent (e.g. washing-up liquid).
R clean cloth covers with a microfibre cloth
moistened with a solution containing 1%
detergent (e.g. washing-up liquid). Rub
carefully, and always wipe entire seat sec-
tions to avoid leaving visible lines. Leave
the seat to dry afterwards. Cleaning results
depend on the type of dirt and how long it
has been there.
R Clean DINAMICA covers with a damp cloth.
Make sure that you wipe entire seat sec-
tions to avoid leaving visible lines.

i Further information can be obtained from
any Mercedes-Benz Service Centre or on the
Internet at http://bevo.mercedes-benz.com. Brake fluid
G
WARNING
The brake fluid continuously absorbs mois-
ture from the air. This results in the boiling
point of the brake fluid lowering. If the boiling
point of the brake fluid is too low, vapour
pockets may form when the brakes are sub-
jected to a heavy load. This would impair brak- ing efficiency. There is a risk of an accident.
Have the brake fluid renewed at the prescri-
bed intervals.
When handling brake fluid, observe the impor-
tant safety notes on service products
(Y page 282).
The brake fluid change intervals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes-
Benz according to MB-Freigabe or MB-Approval
331.0.
Information about approved brake fluid can be
obtained at any qualified specialist workshop or on the Internet at
http://bevo.mercedes-benz.com.
i Have the brake fluid regularly replaced at a
qualified specialist workshop and the replace- ment confirmed in the Service Booklet. Coolant
Important safety notes G
WARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you top up
the antifreeze. Make sure that antifreeze is not spilled next to the filler neck. Thoroughly
clean the antifreeze from components before
starting the engine.
! Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants can be found in the Mercedes-Benz Specifications for Ser-
vice Products, MB Specifications for Service
Products 310.1, e.g. on the Internet at
http://bevo.mercedes-benz.com. Or contact
a qualified specialist workshop.
! Always use a suitable coolant mixture, even
in countries where high temperatures prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
i Have the coolant regularly replaced at a
qualified specialist workshop and the replace- ment confirmed in the Service Booklet.
Comply with the important safety precautions
for service products when handling coolant
(Y page 282).
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It is responsible for
the following:
R anti-corrosion protection
R antifreeze protection
R raising the boiling point
If antifreeze/corrosion inhibitor is present in the
correct concentration, the boiling point of the
coolant during operation will be approximately
130 †.
The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should:
R be at least 50%. This will protect the engine
cooling system against freezing down to
approximately -37 †.
R not exceed 55% (antifreeze protection down
to -45 †). Heat will otherwise not be dissipa-
ted as effectively.
Mercedes-Benz recommends coolant or anti-
freeze/corrosion inhibitor concentrate in
accordance with
MB Specifications for Service Products 310.1.
i When the vehicle is first delivered, it is filled
with a coolant mixture that ensures adequate
antifreeze and corrosion protection. Service products and capacities
