Maintenance and care

Cleaning the seat covers
General notes
!Do notuse microfiber cloths to clean
genuine leather, artificial leather or
Alcantara® covers. If used often, these can
damage the cover.
iNote that regularcare is essential to
ensure that the appearance and comfort of
the covers is retained overtime.
Genuine leather seat covers
Leather is a natural product.
It exhibits natural surface characteristics, for
example:
RDifferences in the texture
RSigns of stretching and marking
RSlightnuances of color
These are characteristics of leather and not
material defects.
!To retain the natural appearance of the
leather, observe the followingcleaning
instructions:
RClean genuine leathercovers carefully
with a damp cloth and then wipe the
covers down with a dry cloth.
RMake sure that the leather does not
become soaked. It may otherwise
become rough and cracked.
ROnly use leather care agents that have
been tested and approved by Mercedes-
Benz. You can obtain these from a
qualified specialist workshop.
Seat covers of other materials
!Observe the following when cleaning:
RClean artificial leather covers with a cloth
moistened with a solution containing
1% detergent (e.g. dish washing liquid).
RClean cloth covers with a microfiber
cloth moistened with a solution
containing 1% detergent (e.g. dish
washing liquid). Rub carefully and always
wipe entire seat sections 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.
RClean Alcantara® covers with a damp
cloth. Make sure that you wipe entire
seat sections to avoid leaving visible
lines.
Cleaning the seat belts
GWARNING
Seat belts can become severely weakened if
bleached or dyed. This could cause the seat
belts to tear or fail, for instance, in the event
of an accident.This poses an increased risk
of injury or fatal injury.
Never bleach or dye the seat belts.
!Do not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts
by heating at temperatures above 176 ‡
(80 †) or in direct sunlight.

Coolant
Important safety notes
GWARNING
If antifreeze comes into contact with hot
components in the engine compartment, it
may ignite. There is a risk of fire and injury.
Let the engine cool down before you add
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 antifreezeprotection. You
could otherwise damage the engine.
Further information on coolants can be
found in the Mercedes-Benz Specifications
for Service 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.
When handling coolant, observe the
important safety notes on service products
(Ypage 345).
The coolant is a mixture of water and
antifreeze/corrosion inhibitor. It performs
the following tasks:
Rcorrosionprotection
Rantifreeze protection
Rraising the boiling point
If the coolant has antifreeze protection down
to -35 ‡ (-37†),the boiling point of the
coolant during operationis approximately
266 ‡ (130 †).
The antifreeze/corrosion inhibitor
concentration in the engine cooling system
should:
Rbe at least 50%. This will protect the engine
cooling system against freezing down to
approximately -35 ‡ (-37 †).
Rnot exceed 55% (antifreeze protection
down to -49 ‡ [-45 †]). Otherwise, heat
will not be dissipated as effectively.
If the vehicle has lost coolant, add equal
amounts of water and antifreeze/corrosion
inhibitor.
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor concentrate in
accordance with MB Specifications for
Service Products 310.1.
The coolant is checked with every
maintenance interval at a qualified specialist
workshop.
iWhen the vehicle is first delivered, it is
filled with a coolant mixture that ensures
adequate antifreeze and corrosion
protection.
