Leave the coolant/antifreeze in the engine cool-
ing system all year round – even in countries
with high outside temperatures.
Check the corrosion inhibitor/antifreeze con-
centration in the coolant every six months.
Only use approved corrosion inhibitors/anti-
freeze agents in accordance with Sheet No.
325.5. This prevents damage to the engine cool-
ing system and engine.
When renewing the coolant, ensure that it con-
tains 50% antifreeze/corrosion inhibitor by vol-
ume. This corresponds to antifreeze protection
down to
Ò
37 †.
Do not exceed 55% by volume (antifreeze down
to approximately
Ò
45 †). The heat dissipation
and antifreeze may otherwise be negatively
affected.
If there is a loss of coolant, do not top it up by
using only water, also add an approved corro-
sion inhibitor/antifreeze agent.
The water in the coolant must meet certain
requirements which are often met by drinking
water. The water must be treated if its quality
does not meet the required standards.
Do not mix the water and the antifreeze/anti-
corrosion additive in the coolant circuit. After-
wards, fill the coolant expansion tank with the
mixture.
Avoid mixing different corrosion inhibitor/anti-
freeze agents.
Observe the Mercedes-Benz Specifications for
Service Products, Sheet No. 310.1.
Further information about operational and road
safety can be obtained from any Mercedes-Benz
Service Centre.
Refrigerant
Important safety notes
Your vehicle's climate control system is filled
with R ‑ 134a refrigerant and contains fluorinated
greenhouse gas.
The instruction label regarding the refrigerant
type used can be found behind the maintenance
flap.
! Only the refrigerant R ‑ 134a and the PAG oil
approved by Mercedes-Benz may be used.
The approved PAG oil may not be mixed with
any other PAG oil that is not approved for
R-134a refrigerant. The climate control sys-
tem may otherwise be damaged.
Maintenance work such as refilling refrigerant
or replacing components may only be carried
out at a qualified specialist workshop. All appli-
cable regulations as well as SAE standard J639
must be adhered to.
Always have all work on the climate control sys-
tem carried out at a qualified specialist work-
shop.
