ume. This corresponds to antifreeze protection
down to
Ò
35 ‡ (
Ò
37 †).
Do not exceed 55% by volume (antifreeze
down to approximately
Ò
49 ‡) (
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.

Service Products, Sheet No. 310.1.

road safety can be obtained from any Freight-

Important safety notes
Your vehicle's climate control system is filled
with R
‑
134a refrigerant and contains fluorina-
ted greenhouse gas.
The instruction label regarding the refrigerant
type used can be found behind the mainte-
nance flap.
!
Only R
‑
134a refrigerant as well as PAG oil
approved by Daimler Trucks North America
may be used. The approved PAG oil must
not be mixed with any PAG oil that is not
approved for R
‑
134a coolant. Otherwise, the
climate control system may be damaged.
Maintenance work such as refilling refrigerant
or replacing components may only be carried
out at a qualified specialist workshop. All
applicable regulations as well as SAE standard
J639 must be adhered to.
Always have all work on the climate control
system carried out at a qualified specialist
workshop.

WARNING
If you mix diesel fuel with gasoline, the flash
point is lower than that of pure diesel fuel.
When the engine is running, exhaust system
components could overheat without being
noticed. There is a risk of fire.
Never refuel with gasoline. Never mix gaso-
line with diesel fuel.
Even small amounts of the wrong fuel may
cause damage to the fuel system, engine and
emission control system.
!
Refuel only with commercially available
vehicle diesel fuel that conforms to the
European standard EN 590 (or equivalent
national fuel standards).

Vehicles with diesel particulate filter: in
countries without sulfur-free diesel fuel,
