In the cooling system, the corrosion inhibi-
tor/antifreeze agent is responsible for:
I
Corrosion protection
I
Antifreeze protection
I
Raising the boiling point
The coolant must remain in the cooling
system all year round for corrosion protec-
tion purposes and to increase the boiling
point – even in countries with hot cli-
mates.
Check the corrosion inhibitor/antifreeze
concentration in the coolant every
6 months.
Have the coolant renewed every 15 years.
When the coolant is being renewed, the
coolant must contain
50 percent by volume of anti-corrosion/
antifreeze agent. This provides antifreeze
protection down to -37 †.
Do not exceed a proportion of
55 percent by volume (antifreeze protec-
tion to approx. -45 †) as otherwise heat
dissipation is reduced.
If there is a loss of coolant, do not replen-
ish with water only, but also add an ap-
proved corrosion inhibitor/antifreeze
agent. The water in the coolant must meet
certain requirements, which are often ful-
filled by drinking water. If the water quality
is not sufficient, you must treat the water.
Observe the Mercedes-Benz Specifica-
tions for Service Products, sheet num-
ber 310.
Further information on the operating reli-
ability and road safety of your vehicle can
be obtained from any Mercedes-Benz
Service Centre.
Coolant additive without antifreeze
protection
! As an exception, if antifreeze protection is
not required (e.g. in countries with continu-
ously hot climates), it is permissible to add a
coolant additive in accordance with sheet num-
ber 312.0 of the Mercedes-Benz Specifica-
tions for Service Products instead of a corro-
sion inhibitor /antifreeze agent. In this case, re-
new the coolant annually. Improvers (corro-
sion-inhibiting oils) are not permitted.
Further information about the necessary water
quality and approved coolant additives without
antifreeze properties can be obtained from all
Mercedes-Benz Service Centres.
Fuel
G
Risk of fire and injury
Fuel is highly flammable.
Fire, naked flames and smoking as well as
the use of auxiliary heaters (sparks) are
therefore prohibited when handling fuel.
For this reason, switch off the auxiliary heat-
ing when refuelling.
G
Risk of injury
Do not allow fuel to come into contact with
skin or clothing.
Allowing fuels to come into direct contact
with your skin or inhaling fuel vapours is
damaging to your health.
! Filter the fuel before transferring it to the
vehicle if you are refuelling the vehicle from
barrels or containers.
This will prevent malfunctions in the fuel sys-
tem due to contaminated fuel.
Fuel for petrol engines
Only use unleaded premium grade fuel of
at least 95 ROZ/85 MON which complies
with European standard EN 228.
