MERCEDES-BENZ SLK ROADSTER 2012 Owners Manual

Additives
!
Do no tuse any additives with the engine
oil. This could damage the engine.
Engine oil viscosity Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity
rating, it flows slowly; the lower the viscosity,
the faster it flows.
Engine oil selection is based on the respective
outside temperatures and in accordance with
the SAE classification (viscosity). The table
shows you which SAE classifications are to be
used. The low-temperature properties of
engine oils can be significantly impaired dur-
ing operation due to, for example, ageing or
soot and fuel accretion. It is therefore
strongly recommended to observe regularo
il
changes using an approved engine oil with the
appropriate SA Eclassification. Brake fluid
G
WARNING
Over a period of time, the brake fluid absorbs
moisture fro mthe air; This lowers its boiling
point.
If the boiling point of the brake fluid is too low,
vapour pockets may form in the brake system
when the brakes are applied hard (e.g. when
driving downhill). This impairs braking effi-
ciency. You should have the brake fluid renewed at
regular intervals. The brake fluid change inter-
vals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes-
Benz.I nformation abou tapproved 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 checked at
a qualified specialist workshop.
There is usually a notice in the engine com-
partment to remind you when the next
brake fluid change is due. Coolant
Important safety notes G
WARNING
Antifreeze is highly flammable. Fire, naked
flames and smoking are prohibited when han-
dling antifreeze.
If antifreeze comes into contact with hot
engine parts, it may ignite and you could burn
yourself. Do not spill any antifreeze on hot
engine parts.
! 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 Service Products, MB Specifications for
Service Products 310.1, e.g. on the Inter-
net 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 coolin gsystem is not
sufficiently protected from corrosion and
overheating.
! The engine cooling system is filled with
coolant, which mus tbe renewed after 308
Service products and capacitiesTechnical data

15 years or after 250,000 kilometres at the
latest.
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
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 operatio nwill be around
130 †.
The antifreeze/corrosio ninhibitor concentra-
tio nint he engine cooling system should:
R be at least 50%. This will protect the engine
cooling system against freezing down to
around -37 †.
R not exceed 55% (antifreeze protection
down to -45 †). Otherwise, heat will not be
dissipated as effectively.
If the vehicle has lost coolant, top it up with
equal amounts of water and antifreeze/cor-
rosion inhibitor. Mercedes-Ben zrecom-
mends an antifreeze/corrosion inhibitor con-
centrate in accordance with MB Specifica-
tions for Service Products 310.1.
The coolant is checked with every mainte-
nance interval at a qualified specialist work-
shop.
i When the vehicle is first delivered, it is fil-
led with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion. Washer fluid
G
WARNING
Windscreen washer fluid/antifreeze is highly
flammable. Avoid spilling windscreen washer
fluid/antifreeze on hot engine components as
it can ignite and burn. Severe burns could be
the result. !
Only use washer fluid that is suitable for
plastic lamp lenses, e.g. MB SummerFit or
MB WinterFit .Unsuitabl ewasher fluid
could damage the plastic lenses of the
headlamps.
! Do no tuse distilled or de-ionised water in
the washer fluid reservoir. Otherwise, the
level sensor may be damaged.
! Only the washer fluids SummerFit and
WinterFit can be mixed. Otherwise, the
spraying nozzles could become blocked.
At temperatures above freezing:
X Fill the washer fluid reservoir with a mixture
of water and washer fluid, e.g. MB Sum-
merFit.
X Mix 1 part MB SummerFit to 100 parts
water.
At temperatures below freezing:
X Fill the washer fluid reservoir with a mixture
of water and washer fluid, e.g. MB Winter-
Fit. Adapt the mixing ratio to the outside
temperatures.
X Down to Ò10 †: mix 1 part MB WinterFit to
2 parts water.
X Down to Ò20 †: mix 1 part MB WinterFit to
1 part water.
X Down to Ò29 †: mix 2 parts MB WinterFit
to 1 part water.
i Add washer fluid concentrate, e.g. MB
SummerFit or MB WinterFit, to the washer
fluid all year round. Service products and capacities

24 GHz radar sensor system (country overview)
The 24 GHz radar senso rsystem requires separat eapproval for each country. If you are driving
in a country in which the radar senso rsystem is no tapproved, you must deactivate the system
using the on-board computer (Y page 194). The current country overview can be obtained
from a Mercedes-Benz Service Centre.
Vehicles with anavigation system: the radar sensor system is deactivated automatically
near radio telescope facilities.
The currently active systems are automatically deactivated:
R DISTRONIC PLUS (Y page 156)
R PRE-SAFE ®
Brake (Y page 59)
Ad isplay message appears in the multifunction display to tell you that the radar sensor system
is being switched off (Y page 214).
BAS PLUS (Y page 54) is the nalso unavailable.
If the deactivation does not occur automatically, you must deactivate the radar sensor system
using the on-board computer (Y page 194).Country Radio telescope
